A Brief History of Typing and Qwerty Keyboards

A typewriter is a small machine, either electric or manual, with type keys that produced characters one at a time on a piece of paper inserted around a roller. Typewriters have been largely replaced by personal computers and home printers. Christopher Sholes Christopher Sholes was an American mechanical engineer, born on February 14, 1819, in Mooresburg, Pennsylvania, and died on February 17, 1890, in Milwaukee, Wisconsin. He invented the first practical modern typewriter in 1866, with the financial and technical support of his business partners Samuel Soule and Carlos Glidden. Five years, dozens of experiments, and two patents later, Sholes and his associates produced an improved model similar to todays typewriters. QWERTY The Sholes typewriter had a type-bar system and the universal keyboard was the machines novelty, however, the keys jammed easily. To solve the jamming problem, another business associate, James Densmore, suggested splitting up keys for letters commonly used together to slow down typing. This became todays standard QWERTY keyboard. Remington Arms Company Christopher Sholes lacked the patience required to market a new product and decided to sell the rights to the typewriter to James Densmore. He, in turn, convinced Philo Remington (the rifle manufacturer) to market the device. The first Sholes Glidden Typewriter was offered for sale in 1874 but was not an instant success. A few years later, improvements made by Remington engineers gave the typewriter machine its market appeal and sales skyrocketed. Typewriter Trivia George K.

My Improvement Project On Myself And My Weight Loss Adventure

I have been slightly overweight for a large part of my life. Since I have retired and started school full time, I have gained a few more pounds. I decided I would like to conduct my improvement project on myself and my weight loss adventure. I have researched why weight loss would benefit me, different weight loss plans, different supplements, and different ways to lose weight. I also researched different exercise regimens. After researching all the information, I committed to a plan and started my journey. Once I started my journey, I followed the Do, Study and Act phases of the PSDA concepts. Let me take you on my journey, starting with my researching and planning. How does one know they are overweight? According to the U.S. Department of Health and Human Services (n.d.), one way to tell whether you are overweight is to figure out what your body mass index (BMI) is. The formula is complicated (weight (lb) / [height (in)]2 x 703), so I utilized a BMI calculator that I found online. Once you find your BMI, then you need to compare it to the standard information on what category you are in. Normal BMI is between 18.5 to 24.9, overweight BMI is between 25 to 29.9 and BMI of 30 and higher is considered obese. To my surprise, I discovered that I was half a point over the overweight category, that put me in the obese category. Due to this information, I have serious health concerns to worry about if I do not change my lifestyle.

Island of the Sequined Love Nun Chapter 27~28 Free Essays

27 Girl Talk Sepie washed the pilot’s hair in a bowl with pounded coconut and brackish water. She had been taking care of the unconscious white man for two days and it was starting to get tedious. She was mispel of the bachelors’ house, and washing and ministering to a sick and stinky white man was not in her job description. We will write a custom essay sample on Island of the Sequined Love Nun Chapter 27~28 or any similar topic only for you Order Now This was women’s work. There are legends in the islands, and some of the old men swear they are true, that the women who service the bachelors’ houses, the mispels, were taken to the secret island of Maluuk, known only to the high navigators, where they were trained in the art of pleasuring a man. After months of training, a mispel was required to pass a test before she was allowed to return to her home island to take over the duty of tending to the sexual needs of the men of the bachelors’ house. The test? She was sent into the ocean with a ripe brown coconut clutched between her thighs, and there she floated, in heavy surf, for the entire circuit of the tides. Should the coconut pop loose or the mispel touch it with her hands, she failed the test (although there was some leeway in the event of shark attack). It is said that the inner thighs of the mispels of old were as strong as net cable. The second part of the test required the girl to find a delicate dragonfly orchid with a straight stem, and while her teachers looked on, she would lower herself over the flower until it disappeared inside of her, then rise again after a few minutes, leaving the stem unbent and the petals unbruised. The mispel held a position of honor, respected and revered among the is-landers. Sh e was not required to do housekeeping, cooking, or weaving, and while the other women toiled in taro fields from the time they could walk, a mispel was allowed to nap in the shade, conserving her energy for her nocturnal duties. A mispel often ended her tour of duty by marrying a man of high status. No stigma followed her into married life, and she would be sought out to the end of her days by the other women for advice on handling men. Sepie, however, had not been chosen because of any special skill, nor had she passed through any vigorous concubinal boot camp. Sepie had been marked for mispel from the moment of her menses, when she emerged from the women’s house with her lavalava tied a bit too high and showing a bit too much cappuccino thigh, her skin rubbed with copra until she glistened all over, and her breasts shining like polished wooden tea cups. She had painted her lips with the juice of crushed berries and peppered her long black hair with scores of sweet jasmine blossoms. She giggled coquettishly in the presence of all the men, danced dangerously close to the taboo of speaking to them in public, risked beatings by refusing to fall to her knees when her male cousins passed, and went about her chores with a wiggly energy that had caused more than one of the distracted village boys to fall out of a breadfruit tree during harvest. (She broke ankles as well as hearts.) Sepie was all titter and tease, a lazy girl who excelled at leisure, a natural at invoking and denying desire, a wet dream deferred. At fifteen she took up residence in the bachelors’ house and had lived there for four years. When Malink and the men brought the flyer and the man in the dress to her, she knew she was in for some trouble. â€Å"Take care of them,† Malink said. â€Å"Feed them. Help to make them strong.† Sepie kept her head bowed while Malink spoke, but when he finished she took his hand and led him into the bachelors’ house, gesturing to the other men to lay the flyer and his friend on the ground outside. The men smiled among themselves, thinking that old Malink was going inside to receive a special favor from the mispel. What, in fact, he was receiving was an ass chewing. â€Å"Why don’t you take them to your house, Malink? I don’t want them here.† â€Å"It’s a secret. If my wife and daughters find out they are here, then everyone will know.† â€Å"I’m the only one who can keep a secret in the bachelors’ house. Take them to old Sarapul’s house. No one goes there.† â€Å"He wants to eat them.† Malink couldn’t remember ever having to argue with a woman and he wasn’t at all prepared for it. â€Å"You’re chief. Tell him not to. I will not cook for them. If I feed them, they will shit. I’m not going to clean it up.† â€Å"Sepie, what will you do when you marry and have children? You will have to do these things then. I am asking you as your chief to do these things.† â€Å"No,† Sepie said. Malink sighed. â€Å"I am asking you to do these things because these men have been sent to us by Vincent.† Sepie didn’t know what to say. She had heard the Sky Priestess chastise Malink in front of the people, but she had been more concerned with losing coffee and sugar for a month than with the actual offense. â€Å"You will tell the men to cook for them?† â€Å"Yes.† â€Å"And they will carry them to the beach and wash them if they shit?† â€Å"I will tell them. Please, Sepie.† No man had ever said â€Å"please† to her before, let alone the chief. It was not a courtesy that women deserved. For the first time she realized how desperate Malink really was. â€Å"And you will tell Abo to wash his dick when it is his turn.† â€Å"What does that have to do with this?† â€Å"He is stinky.† â€Å"I will tell him.† â€Å"And you will tell Favo to quit making me put beads in his ass.† â€Å"Favo does that?† â€Å"He said he learned it from the Japanese.† â€Å"Really? Favo?† â€Å"Yes.† â€Å"But he’s old, and he has a wife and many grandchildren.† â€Å"He says it makes his spear stronger.† â€Å"He does? I mean, does it work?† Malink had momentarily forgotten why he was here. â€Å"I don’t like it. It is evil and unclean.† â€Å"You’re talking about my old friend Favo, right? He’s the one you’re talking about?† â€Å"I told him only bachelors were suppose to stay here, but he says his wife doesn’t understand him. His hands are like the skin of a shark.† â€Å"What kind of beads?† â€Å"Tell him,† Sepie said. â€Å"Okay,† Malink said in English. Then to himself he said: â€Å"Old Favo.† He shook his head as he walked out of the bachelors’ house. â€Å"Beads.† Sepie watched him go, wishing that she had asked for more favors. Outside the men were grinning when Malink stepped into the moonlight. He hitched up his loincloth and averted his eyes from theirs. â€Å"Take them inside. You must cook and clean for them. Don’t let the woman do it. It is too important for her.† As the men carried Tuck and Kimi into the bachelors’ house, Favo ambled up to Malink. â€Å"How was it?† Malink looked at his old friend and noticed for the first time that Favo wore a long string of ivory beads around his neck. â€Å"I have to go home now,† Malink said. Sepie was, once again, swabbing up the wooden floor where the pilot had urinated on himself, when she heard the other one speak for the first time. The men had propped the Filipino up in the corner, where he had sat drinking the coconut milk and fish broth that she had been pouring into the pilot, but except for a few grunts when he made his way outside to urinate, the man in the dress had been quiet for two days. Sepie had learned to ignore him. He didn’t smell as bad as the pilot, and she sort of liked his flowered dress. She’d said a prayer to Vincent for a dress just like it. â€Å"Where is Roberto?† the Filipino said. Sepie jumped. It didn’t surprise her so much that he had spoken, but that he had spoken in her language. Although the words were clipped, the way someone from Iffallik or Satawan might speak. â€Å"He’s right here,† she said. â€Å"Your friend stinks. You should take him outside and wash him in the sea.† â€Å"That’s not Roberto. That’s Tucker. Roberto is shorter.† Kimi crawled over to Tuck and laid his hand on the flyer’s forehead. â€Å"He has bad fever. You have medicine?† â€Å"Aspirin,† Sepie said. Malink had given her a bottle of the tablets to crush into the flyer’s broth, but after he gagged on the first dose she had stopped giving it to him. â€Å"He is more sick than aspirin. He needs a doctor. You have a doctor?† â€Å"We have the Sorcerer. He does our medicine. He was a doctor before the Sky Priestess came.† Kimi looked at her. â€Å"What island is this?† â€Å"Alualu.† â€Å"Ha! We have to get doctor for Tucker. He owes me five hundred dollars.† Sepie’s eyes went wide. No wonder he wears such a fine dress. Five hundred dollars! She said, â€Å"The chief says I have to be secret about this man. Everyone knows he is here. The boys get drunk and talk. But I can’t get the doctor.† â€Å"Why are you taking care of him? You are just a girl.† â€Å"I am not just a girl. I am mispel.† Kimi scoffed. â€Å"There are no mispels anymore.† Sepie threw down the rag she was using to wipe the floor. â€Å"What do you know? You are a man in a dress, and I don’t believe you have five hundred dollars.† â€Å"It was a nice dress before the typhoon,† Kimi said. â€Å"Wash-and-wear. No dry cleaning.† Sepie nodded as if she knew what he was talking about. â€Å"It is a very pretty dress. I like it.† â€Å"You do?† Kimi picked at the crushed pleats around his legs. â€Å"It’s just an old thing I picked up in Manila. It was on sale. You really like it?† Sepie didn’t understand. Among her people, if you admired someone’s else possession, manners bound them to give it to you. How could this silly man speak her language and still not know her customs. And he wasn’t even looking at her that way all men looked at her. â€Å"What island do you come from?† â€Å"Satawan,† Kimi said. â€Å"I am a navigator.† Sepie scoffed. â€Å"There are no more navigators.† Just then the doorway darkened and they looked up to see Abo, the fierce one, entering the bachelors’ house. He was lean and heavily muscled and he wore a permanent scowl on his face. The sides of his head were shaved and tattooed with images of hammerhead sharks. He wore his hair tied into a warrior’s topknot that had gone out of fashion a hundred years ago. â€Å"Has the pilot awakened?† he growled. Sepie looked down and smiled coyly. Abo was the one boy in the bachelors’ house who didn’t seem to accept the communal nature of her position. He was always jealous, enraged, or brooding, but he brought her many presents, sometimes even copies of People that he stole from the men’s drinking circle. Sepie thought she might marry him someday. â€Å"He is too sick for this,† Kimi said. â€Å"We need to take him to the doctor.† â€Å"Malink says he must stay here until he is well.† â€Å"He is dying.† Kimi said. Abo looked at Sepie for confirmation. â€Å"Well, he smells dead,† she said. The sooner they sent the pilot to the Sorcerer, the sooner she could get back to spending her days swimming and preening. â€Å"Malink will be angry if he dies,† she added for good measure. Abo nodded. â€Å"I will tell him.† He pointed to Kimi. â€Å"You come with me.† Kimi got up to leave, then turned back to Sepie when he reached the doorway. â€Å"If Roberto comes, tell him I’ll be right back.† Sepie shrugged. â€Å"Who is Roberto?† â€Å"He’s a fruit bat. From Guam. You can tell by his accent.† â€Å"Oh, him. I think Sarapul ate him,† Sepie said casually.† Kimi turned and ran screaming into the village. Malink looked up from his breakfast, a banana leaf full of fish and rice, to see Abo coming down the coral path toward his house. Malink’s wife and daughters shuffled to the cookhouse at the sight of the fierce one. â€Å"Good morning, Chief,† Abo said. â€Å"Food?† Malink answered, gesturing with his breakfast. Abo had already eaten, but it would have been rude not to accept. â€Å"Yes.† Malink’s wife poked her head out of the cookhouse and saw the chief nod. In a second she was giving her own breakfast to Abo, who neither thanked her or acknowledged her presence. â€Å"The pilot is sick,† Abo said. â€Å"Very bad fever. Sepie and the girl-man say that he will die soon without the Sorcerer’s help.† Malink suddenly lost his appetite. He set his breakfast on the ground and one of his daughters appeared out of nowhere to take it to the cookhouse, where the women shared what was left. â€Å"And what do you think?† Malink asked. â€Å"I think he is dying. He smells of sickness. Like when Tamu was bitten by the shark and his leg turned black.† Malink rubbed his temples. How to handle this? The Sky Priestess was angry with him for even dreaming of the pilot. What would happen if he suddenly showed up with him? â€Å"What about the girl-man?† â€Å"He is not sick, but he has gone crazy. He runs around the village looking for Sarapul.† Malink nodded. â€Å"Catch him and tie him up. Make a litter and take the pilot to the betel nut trees by the runway. Leave him there.† â€Å"Leave him there?† â€Å"Yes, quickly. And bring the litter back with you. Make it look as if he walked to the runway. Send a boy to me when it is done. Go now.† Abo put down his food and ran off down the path. Malink went into his house and pulled the ammo box out of the rafters. Inside, next to the portable phone, he found the Zippo that Vincent had given him. He clicked it open, lit it, and sat it on the floor while it burned. â€Å"Vincent,† he said, â€Å"It’s your friend Malink here. Please tell the Sky Priestess that this is not my fault. Tell her that you have sent the pilot. Please tell her for your friend Malink so she will not be angry. Amen.† His prayer finished, Malink snapped the lighter shut, put it away, then took the portable phone and went outside to wait for the boy to tell him everything was in place. 28 Choose Your Own Nightmare Tucker Case rolled through a fever dream where he was tossed in great elastic waves of bat-winged demons – crushed, smothered, bitten, and scratched – and there, amid the chaos, a pink fabric softener sheet passed by the corner of his eye, confirming that he had been stuffed into a dryer in the laundromat of Hell. He tumbled toward the pink, ascended out of the clawing mass, and awoke gasping, with no idea where he was. The pink was a dress on a heart-faced woman who said, â€Å"Good morning, Mr. Case. Welcome back to the world.† A man’s voice: â€Å"After your message and the typhoon, we thought for sure you’d been lost at sea.† He was a white blur with a head, then a lab coat wrapped around a tall, smiling middle-aged man, gray and balding, a stethoscope around his neck. The doctor had his arm around the heart-faced woman. She too was smiling, with the aspect of an angel, the vessel of human kindness. Together they looked as if they had walked off of fifties television. The man said, â€Å"I’m Dr. Sebastian Curtis, Mr. Case. This is my wife, Beth.† Tuck tried to speak, but emitted only a rasping squeak. The woman lifted a plastic cup of water to his lips and he drank. He eyed the IV bag running into his arm. â€Å"Glucose and antibiotics,† the doctor said. â€Å"You’ve got some badly infected wounds. The islanders found you washed up on the reef.† Tucker did a quick inventory of his limbs by feel, then looked at them lest he had lost a leg that was still giving off phantom feel ing. He raised his head to look at his crotch, which was sending pulses of pain up through his abdomen. The woman gently pushed him down. â€Å"You’re going to be fine. They found you in time, but you’re going to need more rest. ‘Bastian can give you something for the pain if you need it.† She smiled beatifically at her husband, who patted Tuck’s arm. â€Å"Don’t be embarrassed, Mr. Case. Beth is a surgical nurse. I’m afraid the catheter will have to stay in for a few days.† â€Å"There was another guy with me,† Tuck said. â€Å"A Filipino. He was piloting the boat.† The doctor and his wife shot each other a glance and the â€Å"Ozzie and Harriet† calm shattered into panic, but only for a second, then they were back to their reassuring cooing. Tuck wasn’t even sure he had seen the break. â€Å"I’m sorry, but the islanders didn’t find anyone else. He must have been lost in the storm.† â€Å"But the tree. He was hung in the tree†¦Ã¢â‚¬  Beth Curtis put her finger gently on his lips. â€Å"I’m sorry you lost your friend, Mr. Case, but you need to get some rest. I’ll bring you something to eat in a little while and we’ll see if you can hold down some solid food.† She pulled her hand away and put her arm around her husband’s waist as he pushed a syringe of fluid into Tuck’s IV tube. â€Å"We’ll check on you shortly,† the doctor said. Tucker watched them walk away and noticed that for all her â€Å"Little House on the Prairie† purity, Beth Curtis had a nice shape under that calico. Then he felt a little sleazy, as if he’d been caught horning on a friend’s mom. Like the time, drunk and full of himself, he’d hit on Mary Jean Dobbins. To hell with solid food. Gin – in large quantities over a tall column of ice – that’s the rub. Tonic to chase away the blues of bad dreams and men lost at sea. Tuck looked around the room. It was a small hospital ward. Only four beds, but amazingly clean considering where it was. And there was some pretty serious-looking equipment against the walls: technical stuff on casters, stuff you might use in complicated surgery or to set the timing on a Toyota. He was sure Jake Skye would know what it was. He thought about the Learjet, then felt himself starting to doze. Sleep came with the face of a cannibal, leg-jerk dreams, and finally settled in on the oiled breasts of a brown girl brushing against his face and smelling of coconut and flowers. There was a scratch and scuttle on the tin roof, followed by the bark of a fruit bat. Tuck didn’t hear it. The pig thief had been caught and Jefferson Pardee had to find a new lead story. He sat at his desk pouring over the notes he’d written on a yellow legal pad, hoping that something would jump out at him. In fact, there wasn’t a lot of jumping material there. The notes read: â€Å"They caught the pig thief. Now what?† You could run down the leads, pound the pavement, check all your facts with two sources, then structure your meticulously gathered information into the inverted pyramid form and what you got was: The pig’s owner had gotten drunk and beat up his wife, so she sold his pig to someone on the outer islands and bought a used stun gun from an ensign with the Navy Cat team. The next time her husband got rough, a group of Japanese tourists found him by the side of the road, sizzling in the dirt like a strip of frying bacon. Mistaking him for a street performer, the tourists clapped joyously, took pictures of each other standing beside the electrocuted man, and gave his wife five dollars. The whole intrigue had been exposed when police found the pig-stealing wife in front of the Continental Hotel charging tourists a dollar apiece to watch her zap her husband’s twitching supine body. The stun gun was confiscated, no charges were pressed, and the wife beater was pronounced unharmed by a Peace Corps volunteer, although he did need to be reminded several times of his name, where he lived, and how many children he had. The mystery was solved and the Truk Star had no lead story. Jefferson Pardee was miserable. He was actually going to have to go out and find a story or, as he had done so many time before, make one up. The Micro Spirit was in port. Maybe he’d go down to the dock and see if he could stir up some news out of the crew. He slid his press card into the band of his Australian bush hat and waddled out the door and down the dusty street to the pier where rock-hard, rope-muscled islanders were loading fifty-five-gallon drums into cargo nets and hoisting them into the holds of the Micro Spirit. The Micro Spirit and the Micro Trader were sister ships: small freighters that cruised the Micronesian crescent carrying cargo and passengers to the outer islands. There were no cabins other than those of the captain and crew. Passengers traveled and slept on the deck. Pardee waved to the first mate, a heavily tattooed Tongan who stood at the rail chewing betel nut and spitting gooey red comets over the side. â€Å"Ahoy!† Pardee called. â€Å"Permission to come aboard.† The mate shook his head. â€Å"Not until we finish loading this jet fuel. I’ll come down. How you doing, Scoop?† Pardee had convinced the crew of the Micro Spirit to call him â€Å"Scoop† one drunken night in the Yumi Bar. He watched the mate vault over the railing at the bow and monkey down a mooring line to the dock with no more effort than if he was walking down stairs. Watching him made Pardee sad that he was a fat man. The mate strolled up to Pardee and pumped his hand. â€Å"Good to see you.† â€Å"Likewise,† Pardee said. â€Å"Where you guys in from?† â€Å"We bring chiefs in from Wolei for a conference. Pick up some tuna and copra. Same, same.† Pardee looked back at the sailors loading the barrels. â€Å"Did you say jet fuel? I thought the Mobil tankers handled all the fuel for Continental.† Continental was the only major airline that flew Micronesia. â€Å"Mobil tankers won’t go to Alualu. No lagoon, no harbor. We going to Ulithi, then take this fuel special order to the doctor on Alualu.† Pardee took a moment to digest the information. â€Å"I thought the Micro Trader did Yap and Palau States. What are you going all the way over there for?† â€Å"Like I say, special order. Moen has jet fuel, we here in Moen, doctor wants jet fuel soon, so we go. I like it. I never been Alualu and I know a girl on Ulithi.† Pardee couldn’t help but smile. This was a story in itself. Not a big one, but when the Trader or the Spirit changed schedules it made the paper. But there was more of a story somewhere in those barrels of jet fuel, in the ru-mor of armed guards, and in the two pilots that had passed through Truk on the way to No One’s Island. The question for Pardee was: Did he want to track it down? Could he track it down? â€Å"When do you sail?† he asked the mate. â€Å"Tomorrow morning. We get drunk together tonight Yumi Bar. My boys carry you home if you want. Hey?† The mate laughed. Pardee felt sick. That was what they knew him for, a fat, drunken white man who they could carry home and then tell stories about. â€Å"I can’t drink tonight. I’m sailing with you in the morning. I’ve got to get ready.† The mate removed the betel nut cud from his cheek and tossed it into the sea, where tiny yellow fish rose to nip at it. He eyed Pardee suspiciously. â€Å"You going to leave Truk?† â€Å"It’s not that big a deal. I’ve gone off-island before for a story.† â€Å"Not in ten years I sail the Spirit.† â€Å"Do you have room for another passenger or not?† â€Å"We always have room. You know you have to sleep on deck?† Pardee was beginning to get irritated. He needed a beer. â€Å"I’ve done this before.† The mate shook his head as if clearing his ears of water and laughed. â€Å"Okay, we sail six in morning. Be on dock at five.† â€Å"When do you come back this way?† â€Å"A month. You can fly from Yap if you don’t want to come back with us.† â€Å"A month?† He’d have to get someone to run the paper while he was gone. Or maybe not. Would anyone even notice he was gone? Pardee said, â€Å"I’ll see you in the morning. Don’t get too drunk.† â€Å"You too,† the mate said. Pardee made his way down the dock, feeling every bit of his two hundred and sixty pounds. By the time he made it back to the street, he was soaked with sweat and yearning for a dark air-conditioned bar. He shook off the craving and headed for the Catholic high school to ask the nuns if they had any bright students who might keep the paper running in his absence. He was going to do it, dammit. He’d be on the dock at five if he had to stay up all night drinking to do it. How to cite Island of the Sequined Love Nun Chapter 27~28, Essay examples

Research on Haiti free essay sample

Haiti is also made up of several islands that surround the main territory. The capital is Port-au-Prince. It rains between November and March in the North of the island and between May and October in the South. Once covered by forest, the country has been heavily logged for wood and fuel and to clear land for farming, and is now largely deforested. Haiti is divided into nine administrative departments. Besides the capital, other mportant cities are Cap-Haitien and Gonaives. Haiti is the most densely populated country in Latin America and has the lowest per capital income, with about half the people unemployed and three quarters living in the severest poverty. Agriculture is the main economic activity in Haiti. The main crops grown are cassava, rice, sugarcane, sorghum, yams, corn, and plantains. The main exports are coffee, cotton, sugar, sisal, bauxite, and essences. The most predominant religion is Roman Catholicism. Catholicism is enshrined in the Haitian constitution as the official state eligion, and between 80 and 85% of Haitians are Catholics. We will write a custom essay sample on Research on Haiti or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The religion of Voodoo is also practiced. Nodou encompasses several different traditions, and consists of a mix encompassing African, European and indigenous Taino religious elements. It is unknown how many people practice Voodoo, but many practice it along with their Christian faith. Haiti has a rich culture that comes mostly from voodoo tribes. Haitian culture is a mixture of French, African elements, and native Taino, with influence from the colonial Spanish. The countrys customs essentially are a blend f cultural beliefs that derived from the various ethnic groups that inhabited the island of Hispaniola. In nearly all aspects of modern Haitian society however, the European and African elements dominate. Haiti is world famous for its distinctive art, notably painting and sculpture. The Dominican War of Independence gave the Dominican Republic independence from Haiti. Before the war, the whole island of Hispaniola had belonged to Haiti for 22 years. The Dominican War of Independence of 1844 was led by twenty year old Juan Pablo Duarte. Duarte along with Matias Ramon Mella and Francisco del Rosario Sanchez formed a group they called La Trinitaria or the Trinity. They recruited many people and kept their actions very secret to avoid detection by any Haitian authorities. The group was eventually discovered and it was forced to change its name to La Filantropica or The Philanthropic. The group continued to make trouble for the Haitians. In 1843 the group had a break as it worked with a liberal Haitian party they were able to overthrow the president. Their success continued and on February 27, 1844, Dominican rebels seized the Fortaleza Ozama in Santo Domingo. Within days all Haitian officials left Santo Domingo. The war continued and the Dominican Republic continued to defend against Haitian attacks. The Republic went on to win more wars against Haitis attacks. In November 6, 1844 a Constituent assembly drafted a constitution, based on the Haitian and United States models, which established separation of powers and legislative checks on the executive. The independence was foreseeable as tensions built over the twenty two years in which Haiti had control of the island. The relationship between Haitians and the Dominican Republic deteriorated as Haitians monopolized government power, severed the churchs ties with Rome, forced out the traditional ruling class, and all but obliterated the western European and Hispanic traditions. In addition, Haitian troops arbitrarily confiscated foodstuffs and other supplies, and ethnic tensions caused further resentment. Many Dominican historians have painted a picture of this period as cruel and barbarous. The aftermath of Haitis earthquake has had a clear devastating impact on the capital, Port-au-Prince. The National Palace, the Cathedral, the Ministry of Justice nd other important Government offices have been destroyed. Hotels, hospitals, schools and the national penitentiary have all suffered extensive damage. Buildings and infrastructure were heavily damaged throughout the capital. Basic services such as water and electricity have collapsed almost entirely. The remaining areas of Haiti appear to be largely unaffected. The destruction that the earthquake has caused is massive and the country is still very visibly shaken up as the casualties were vast, the destruction of homes immense, the water supply is short, and there are shortages of ssential items. Over 222,570 people have died, 300,572 injured and a staggering 2. 3 million, nearly one quarter of the population, displaced. The government lost thousands of civil servants and most of their key infrastructure was destroyed. Haitis present day situation is very grim. If you visit Haiti today it seems as if the earthquake had Just taken place. Less than four percent of the debris has been cleared, 1. 6 million people are still living in tents, and all of this is despite $1. 8 billion in earthquake aid, according to US government and United Nations figures. Haitis government is going to receive a significant portion of aid and its leaders will be left to fgure out how to spend the money and where to distribute it.

What History Is To A Nation, Memory Is To The Individual. Both Serve T

What history is to a nation, memory is to the individual. Both serve to locate us, to tell us who we are by reminding us of what we have been and done. And both, as Kazuo Ishiguro suggests, are open to selection, repression and revision. The Remains of the Day, Ishiguro's third novel, examines the intersections of individual memory and national history through the mind of Stevens, a model English butler who believes that he has served humanity by devoting his life to the service of a great man, Lord Darlington. The time is 1956; Darlington has died, and Darlington Hall has been let by an American businessman. As Stevens begins a solitary motor trip to the west country, traveling farther and farther from familiar surroundings, he also embarks on a harrowing journey through his own memory. What he discovers there causes him to question not only Lord Darlington's greatness, but also the meaning of his own insular life. The journey motif is a deceptively simple structural device; the far ther Stevens travels from Darlington Hall, it seems, the closer he comes to understanding his life there. But in Stevens's travel journal Ishiguro shapes an ironic, elliptical narrative that reveals far more to the reader than it does to Stevens. The butler believes, for instance, that he makes his trip for professional reasons, to persuade a former housekeeper, Miss Kenton, to return to Darlington Hall. But through deftly managed flashbacks and Stevens's naive admissions, the reader sees instead that the matter is highly personal: Stevens had loved Miss Kenton but let her marry another man; he now wishes to make up for lost time, to correct the mistakes of his past. More important than that veiled love story--but intimately connected with it--is the matter of Lord Darlington, and the degree to which Stevens's sense of self is founded upon his belief in Darlington's greatness. It becomes clear enough to the reader, though Stevens is long in admitting it to himself, that Darlington h ad been a political pawn of fascism and the Nazis--unwitting perhaps, misguided no doubt, but hardly the great man that Stevens had deceived himself into believing he served. These revelations are made through a delicate and powerful process: as Stevens's journal shifts between travelogue, personal memoir and reflections on his profession, his memory slides continually between Darlington Hall in the ruined, empty present, the height of Darlington's influence (and Stevens's pride) in the 1920s, and the tense, disturbing pre-war 1930s. Carefully elided from consideration, repressed and hidden, are the war years themselves and their immediate aftermath. We know they are there, of course, and we may guess what they meant at Darlington Hall, but Stevens's memorial archaeology leaves that particular tomb unexcavated. In the end, Stevens must come to some sense of resignation and resolution, both about Darlington and about himself. The source of Stevens's pride is also, after all, potentia lly the source of his shame. He was willing enough to shine in the light of Darlington's greatness, and now must either share in his disgrace, or--what is perhaps more difficult--admit that his own dedicated and deeply considered professionalism has had no real part to play on the stage of world history. Like all great novels, The Remains of the Day is an organic work, its parts perfectly integrated, every scene imaging the whole. In his carefully controlled prose, so perfectly suited to his narrator, in his effortless movement among several different time settings, in his almost magical evocation of simultaneous humor and pathos, Ishiguro proves himself a masterful artist in full command of his elements. And in this novel, those elements combine to form a profound psychological and cultural portrait that reveals the author's great abiding theme: the art and artifice of memory

Leading a Book Club Discussion Session

Leading a Book Club Discussion Session Whether you are an outgoing extrovert or the shy one in the group, you can lead your book club in an engaging discussion by following these few simple steps. What to Do Before the Meeting Read the book.  This may seem obvious, but it is the most important step, so it is worth stating. It is a good idea to plan on finishing the book a little earlier than you might otherwise so that you have time to think about it and prepare before your book club meets. If you get to pick the book, here are some recommendations for engaging books  that are likely to promote discussion. Write down important page numbers (or bookmark in your e-reader).  If there are parts of the book that made an impact on you or that you think may come up in the discussion, write down the page numbers so that you can access the passages easily while preparing and leading your book club discussion. Come up with eight to ten questions about the book.  There are some general book club discussion questions that should work on most books, especially popular selections and bestsellers. Print them out and you are ready to host. You can also come up with your own questions using the tips below as a guide. What to Do During the Meeting Let others answer first.  When you are asking questions, you want to facilitate discussion, not come off as a teacher. By letting others in the book club answer first, you will promote conversation and help everyone feel like their opinions matter. Its important to note that sometimes people may need to think before they answer. Part of being a good leader is being comfortable with silence. Dont feel like you have to jump in if no one answers immediately. If needed, clarify, expand or rephrase the question. Make connections between comments.  If someone gives an answer to question 2 that connects well with question 5, dont feel obligated to ask questions 3 and 4 before moving to 5. You are the leader and you can go in whatever order you want. Even if you go in order, try to find a link between an answer and the next question. By connecting peoples comments to the questions, youll help build momentum in the conversation. Occasionally direct questions toward quiet people.  You dont want to put anyone on the spot, but you want everyone to know their opinions are valued. If you have a few talkative people who always jump right in, directing a question to a specific person may help draw out the quieter people (and give the more animated people a hint that its time to give someone else a turn). Rein in tangents.  Book clubs are popular not only because people like to read, but also because they are great social outlets. A little off topic conversation is fine, but you also want to respect the fact that people have read the book and expect to talk about it. As the facilitator, it is your job to recognize tangents and bring the discussion back to the book. Dont feel obligated to get through all the questions.  The best questions sometimes lead to intense conversations. Thats a good thing! The questions are there simply as a guide. While you will want to get through at least three or four questions, it will be rare that you finish all ten. Respect peoples time by wrapping up the discussion when the meeting time is over rather than pushing on until you finish everything you planned. Wrap up the discussion.  One good way to wrap up a conversation and help people summarize their opinions of the book is to ask each person to rate the book on a scale of one to five. General Tips When writing your own book club discussion questions, avoid questions that are too general, like What did you think of the book? Also, avoid questions that have simple yes or no answers. You want to ask questions that are open-ended and help people talk about themes and how the book relates to deeper issues.Do not make dismissive statements toward other peoples comments. Even if you disagree, take the conversation back to the book rather than saying Thats ridiculous, etc. Making people feel embarrassed or defensive is a sure way to shut down the conversation.

How do you grade creativity in the classroom Essay

How do you grade creativity in the classroom - Essay Example In a classroom it is possible that creativity level in the student, who is achieving high grades, is at low level and creativity level in a student who is performing not well and achieving low grades, is at high level. In this kind situation, it is now own teacher that how he will assess the creativity level of any student. Short Introduction of Toolmin model: Stephen Edelston Toulmin who was a British philosopher presented a model for presenting the arguments in well prepared form. He stated that for the success of any good argument it is necessary to provide good presentation and justifications about argument. He expressed his philosophy in six different ways those are correlated to each other. According to Toulmin there are three necessary parts of any argument and other three are can be treated as optional or additional parts. Those six parts include claim, support, warrant, backing, rebuttal and qualifier. How do you grade creativity in the classroom? How to you grade creativity in the class room? That is the main question that is rising in these days. Creativity grading of a student is necessary for any student to judge the level of creativity in classroom. As the creativity is not the separate faculty that some people have and others do not. (Ken Robinson). Everyone is creative but the variance in the ways of work might be possible. For example a student writes 10 pages in with the help of pencil in given time period but on the other side other second student cannot write 10 pages in given time period. Simply any one can state the first student worked better than the second student. From above mentioned results can we assume that that fist student is more creative than second student? Most of the teachers those are not able to grade the creativity level of any student will answer that Yes, First student is more creative than Second student because he can write 10 pages in the given time period. But this statement is not true practically. WHY? The reason can be found as seeing on the other side of coin, second student can draw 10 drawings with help of the pencil in given time period. On the other hand same first student is unable to draw same work in given time period. In above scenarios all the things are same excluding the nature of the work. E.g. students are same, pencils are same even pages are same but the difference is that both of student can only work better in which they are creative. Generally, as described in above example creativity is not exclusive to particular activities. And the level of grading the creativity level in class room is also not exclusive to particular judgments. Students can come up with more creative ideas; this can only be possible if the student will give proper attention in the field that he thinks he can work better than others. Creativity is a key for success in entire life. The example of this can be described as people can do their best in their own work. E.g. Scientists, Technologists, busines s man, educators can only be creative in the work they do. As in current modern environment it is noted that the generation becoming ever more difficult to engage in a traditional classroom environment. These students are also referred as â€Å"digital kids†. It is the generation that needs some creative inspiration. Now the next thing depend on teachers that how they inspire creativity. How they train the students to the best things. Creative Processing for the students are rooted in imaginative

The Importance to Teach Through the Standards in Science Curriculum Essay - 2

The Importance to Teach Through the Standards in Science Curriculum - Essay Example Science curriculum should be taught by following the standards that must be designed according to the environment of students so that they can make use of their science knowledge in their practical lives. The development of science education has structured more and more recently. So, by looking back at the last century, the curriculum of schools was very basic and everybody used to think about multi-curriculum from his own angle. More in-depth, teaching strategies were clustered around the teacher himself, and he was the center of the classroom. In the beginning, scientists were the one who used to control the science curriculum, and they had the authority for choosing the content to be taught in schools. Thus, it was hard for teachers and students to handle the science subject based on the scientists’ perspective rather than science educators’ perspectives. However, the reformation that was called for by Dewey had taken place in the late 1950s. The development of teaching science as the inquiry has taken place in the 1950s, nevertheless, the years 1955-1974 were called the Golden Age in Education. Numerous findings were poured into education in order to develop curriculum. The 1960s were even enriched with more science projects toward the science curriculum but the reformation was not very clear, until late 1960s when studies showed some achievements and attitude toward science. During the 1970s, the focus of NSF (The National Science Foundation) was on exploring the impact of the new science curriculum such as improving science methods, working in labs and discovering inquiry learning. In the 1980s and 1990s, the development of technology, computer and the World Wide Web were enough to call it a new reformation besides that the beginning of 1990s, it was the beginning of something new, it was the standard era. The complexity of the lifestyle after the 1990s was not only sensed in the States but globally too and the science education became a field for competition through many different

Celebrating Thanksgiving in America Annotated Bibliography

Celebrating Thanksgiving in America - Annotated Bibliography Example This web article was authored by David Barton. The source provides a detailed historical background to the Thanksgiving Day as celebrated in America today. The source relies on several primary sources to bring to life the events that led to the institution of the last Thursday of November as a public holiday and national day of celebration. According to the author, the celebration of Thanksgiving in America is a tradition that was introduced by European Americans more than four centuries ago. Barton notes that Thanksgiving Day traces its history to the arrival of the pilgrims from England to the New England. He notes that Thanksgiving Day is not only a day to celebrate by feasting but is dedicated to giving thanks to God for His blessings. According to the source, the first congressional resolution for the institution of Thanksgiving Day as a federal holiday was declared by President George Washington in 1789. The president declared November 26, 1789, as a holiday. In this book, Colman seeks to explore the origin the celebrations that are held in the U.S. every last fourth Thursday of November. Colman ideally seeks to answer the question as to whether the Thanksgiving Day really traces its origins to the arrival of the Pilgrims in Plymouth, Massachusetts as commonly stated. The author gives different accounts of past happenings that together point at different origins of the Thanksgiving Day. Pertinent to her discourse is the symbolic eating of turkeys on Thanksgiving Day. According to the author, many Americans love to celebrate together on Thanksgiving Day and often have turkey - a symbol of abundance - as part of their diet.

Step by step design of a lock

Step by step design of a lock Introduction This paper outlines the step by step design of a lock in amplifier based micro-ohmmeter. This is very useful in measuring small resistances without applying large currents. And find its usefulness in tracing short circuits on printed boards containing sensitive components. The Audio Micro Ohm Meter uses synchronous detection to measure low value resistances. The circuit provides a variable frequency audio tone to indicate the resistance under test. Such a tone is invaluable when troubleshooting shorted tracks on multi-layer circuit boards because it is easier and quicker to observe 1. The source generates a 1KHz, 250mV peak square wave carrier signal that is injected into the unknown resistance, the resulting voltage across the resistor is amplified by the instrumentation amplifier. The phase reversing switch then rectifies the complementary square wave input, the rectified output is not all smooth so a low pass filter is needed. A Voltage controlled is then used to measure and indicate low value resistances such as track resistances on printed circuit boards. To provide a convenient indication, we want a ‘display that has high resolution (like a digital display) but is easy to read (like analogue meter) and that preferably doesnt even need to be looked at, so we can concentrate on the probes. To trace short circuits, the one thing we dont really need is high accuracy, since we are generally moving the probes 1. A muting detector then comes in to compare the control voltage with reference voltage. The Proteus ISIS software is used for the simulation of the circuit while a printed circuit board was used for the verification of the circuit. Resistor selection, analysis of waveforms , sensitivity and linearity of the device to supply voltage and possible improvements of the device were discussed. Excitation Oscillator One of the most useful ICs ever made is the 8-pin 555 timer and it is used in many projects. It can be used to build many circuits by just adding a few external components. NE555 is a popular version and it is suitable in most cases where a 555 timer is specified. Some low power types of the 555 are made, for instance the ICM7555, but can only be used when specified (to increase battery life) because their maximum output current of about 20mA (with a 9V supply) is too low for many standard 555 circuits. The ICM7555 has the same pin arrangement as a standard 555. The circuit symbol for a 555 is a box with the pins arranged to suit the circuit diagram: for example 555 pin 8 at the top for the +Vs supply, 555 pin 3 output on the right. Usually just the pin numbers are used and they are not labeled with their function. Standard 555 ICs create a significant glitch on the supply when their output changes state. This is not a problem in small circuits with no other ICs, but in a complex circuit a smoothing capacitor can be connected across the +Vs and 0V supply near the 555 . The 555 timer operates in different modes. The astable mode suits our design criteria. An astable circuit produces a square wave, this is a digital waveform with sharp transitions between low (0V) and high (+5Vs). It is possible that the durations of the low and high states may be different. The circuit is called an astable because it is not stable in any state: the output is continually changing between low and high. Our circuit needs a square waveform output of 4KHz, for this to be obtained an appropriate resistor value can be estimated by calculation to obtain the needed signal to drive the circuit Duty cycle The duty cycle of an astable circuit is the proportion of the complete cycle for which the output is high (the mark time). It is usually given as a percentage. The duty cycle of our circuit can be determined using Time period. The timeperiod (T) of the square wave is the time for one complete cycle, but it is usually better to consider frequency (f) which is the number of cycles per second 2. The time period can be split into two parts: T = Tm + Ts 5 Mark time (output high): Tm = 0.7 Ãâ€" (R1 + R2) Ãâ€" C1 Space time (output low): Ts = 0.7 Ãâ€" R2 Ãâ€" C1 we can determine our R2 using C3= 10nF, R1=1k and f= 4kHz we calculate our R2 as Tm = 0.7 X (1K + 33K) X 10 X 10^-9 = 238 ÃŽ ¼s While Space-time represents low output, Ts= 0.7 Ãâ€" R2 Ãâ€" C1 Ts = 0.7 X (1K) X 10 X 10^-9 = 0.7 ÃŽ ¼s T = Tm + Ts = 238 + 0.7 = 238.7 ÃŽ ¼s Duty cycle = = 99.7% The Quadrature Divider A quadrature divider, comprises a plurality of flip-flops, it includes at least two flip-flop, the flip-flops are interoperably coupled in series to produce a set dividing ratio 7. Each of the flip-flops includes two differential inputs I, two differential outputs O, and two differential clock inputs C, the outputs O, of one flip-flop is connected to the inputs I, of the next flip-flop, the outputs O, of the last flip-flop is connected inversely to the inputs I, of the first flip-flop, the flip-flops are clocked at their clock inputs C with differential clock signals in a consecutive manner which, for each flip-flop, are individually selected from quadrature clock input signals, 0, 90, 180, and 270, the quadrature divider is an even number divide-by-n circuit comprising a number of 2n flip-flops and providing a number of 4n output signals having 4n equidistant phases. 9 In our case the quadrature divider receives the square waveform signal from excitation oscillator as its clock signal . Figure 4 and 5 of the appendix show the pictorial representation of the quadrature divider as obtained from the circuit simulation and the oscilloscope graphic display. There are four output signals from the quadrature divider and they each have amplitude of about 5V but frequency of 1 KHz. This shows that the quadrature divider effectively divides the clock frequency into four amongst the equidistant phases. Attenuator An attenuator is a circuit that allows a known source of power to be reduced by a known factor usually expressed in decibels. The main advantage of an attenuator is that it is made from non-inductive resistors and therefore able to change a source or load, which might be reactive, into a resistive one that is know. The power reduction is achieved by the attenuator without introducing distortion. The attenuator used in our circuit is a pi type It is used to attenuate the 0 and 180 degrees antiphase 5V signal form the quadrature divider to 250mV at 1KHz. In order to get this value we need to select R5 in this attenuator circuit. Using Thevenins theorem. RTH = R5// (R3 + R4) where RTH = 100 ohms, R3 = 1K1ohms and R4 = 1K1 ohms. R5 = = 104.76 ohms. The best resistor to this to this value is a110 ohms resistor. So R5 = 110 ohms. figure 6 of the Appendix shows the graphical output of the attenuator with amplitude of about 250mV and frequency of 1 KHz. The attenuators gain in decibels is obtained by finding the ratio of the voltage corresponding to a known factor. Using the formula: , where R1 = 1100 ohms and the Z = 100, K = = 1.2 The value of attenuation, A in dB is obtained using K = 10 (A / 20) 1.2 = 10 (A / 20) A = 20 log 1.2 = 1.584 dB Instrumentation Amplifier An instrumentation amplifier is a variation of differential amplifier with input buffers that eliminates the need for input impedance matching making the amplifier suitable for use in measurement 5. It is a differential op-amp circuit providing high input impedances with the pleasure of gain adjustment through the adjustment of a single resistor. Instrumentation amplifier has very low DC offset, low drift, low noise, very high open-loop gain, very high common-mode rejection ratio, and very high input impedances. The instrumentation amplifier used in this circuit affected its accuracy and stability. The attenuated signal is applied across a resistor with very small resistance. The voltage drop across the resistor is small and needs to be amplified. The instrumentation amplifier does this, it composes of three op-amps arranged so that there is one op-amp to buffer each input signal and one to produce the desired output with adequate impedance matching for the function.3 The gain of the instrumentation amplifier circuit used for this micro-ohmmeter design is known to be 60 dB. Using the formula below then, Av =where AV = 60 dB, R = 10 k, 60 =, R9 = = 338.98 ÃŽ © The best resistor to this value is 340 ÃŽ © and it controls the gain of the instrumentation amplifier. The negative feedback of U3:A makes the voltage at pin 2 of U3:A to be equal to Voltage across R8. while, the voltage at pin 6 of U3:B is held to a value equal to Voltage across R14. This establishes a voltage drop across R9 equivalent to the voltage difference between V1 and V2 and subsequently a current through R9 and since no current is drawn by the feedback loops of the two input op-amps , the same amount of current through R9 must be going through R10 and R12 resistors above and below it. This produces a voltage drop between points A and B equal to V The ordinary differential amplifier part of the circuit then amplifies this voltage drop by a gain of 1. The post- differential amplifier circuit, with gain = R19 / R15 and differential input resistance = 2*R15. The two amplifiers on the left are the buffers. With R9 = Rgain removed (open circuited), they are simple unity gain buffers; the circuit will work in that state, with gain simply equal to R19 / R15 and high input impedance because of the buffers. The buffer gain is increased by putting resistors between the buffer inverting inputs and ground to shunt away some of the negative feedback; however, the single resistor Rgain between the two inverting inputs is a much more elegant method: it increases the differential-mode gain of the buffer pair while leaving the common-mode gain equal to 1. This increases the common-mode rejection ratio (CMRR) of the circuit and enables the buffers to handle much larger common-mode signals without clipping than would be the case if they were sep arate and had the same gain. Another benefit of the method is that it boosts the gain using a single resistor rather than a pair, thus avoiding a resistor-matching problem. The ideal common-mode gain of an instrumentation amplifier is zero. The common-mode gain of the instrumentation amplifier used in this design is near zero because of the equally numbered resistors and by the matched common-mode gains of the two buffer op-amps of the instrumentation amplifier. To obtain a closely matched resistors is difficult, as is optimizing the common mode performance of the input op-amps. All resistors are of equal value for this instrumentation amplifier except for R9. This method has the advantage of possessing extremely high input impedances on the input voltage across R=39 because they connect straight into the non-inverting inputs of their respective op-amps and adjustable gain that can be set by a single resistor. The lowest gain possible is obtained from the above circuit with R9 completely open (infinite resistance), and that gain value is 1. The output of the instrumentation amplifier is an anti-phase square wave signal from the that connects to the phase shift detector for further modification. Lock-In Amplifier A lock-inamplifier otherwise known as a phase-sensitive detector is a type of amplifier that can extract a signal with a known carrier wave from extremely noisy environment. It is a homodyne with a very low pass filter making it very narrow band. Lock-in amplifiers utilizes mixing, via a frequency mixer, to convert the signals amplitude and phase to a DC—in fact a time-varying low-frequency—voltage signal. It is often used to measure phase shift, even when the signals are of a high value and of high signal-to-noise ratio, and do not need any other improvement.To obtain signal at low signal-to-noise ratios, it is necessary that a strong, undiluted reference signal is made available at the same frequency as the signal to be measured. Phase Difference Two oscillators that have the same frequency and different phases that is, a phase difference, the oscillators are said to be out of phase with each other. The amount by which such oscillators are out of step with each other can be expressed in radians from 0 to 2Ï€ or in degrees from 0 ° to 360 °, If the phase difference is 180 degrees (Ï€ radians), then the two oscillators are said to be in antiphase. If two interacting waves meet at a point where they are in antiphase, then destructive interference will occur. It is common for waves of electromagnetic (light, RF), acoustic (sound) or other energy to become superposed in their transmission medium. When that happens, the phase difference determines whether they reinforce or weaken each other. Complete cancellation is possible for waves with equal amplitudes. Phase compensation This is the correction of phase error (i.e., the difference between the actually needed phase and the obtained phase). To obtain stability in an operational amplifier a phase compensation is required. To keep a phase margin in the phase compensation a capacitor/RC network is usually used . A phase compensator works by subtracting out an amount of phase shift from a signal which is equal to the amount of phase shift added by switching some additional amplifier stages into the amplification signal path. Low-Pass Filter A low-pass filter is a filter that passes low-frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. An ideal low-pass filter completely eliminates all frequencies above the cutoff frequency while passing those below unchanged: its frequency response is a rectangular function, and is a brick-wall filter 8. If we need to get rid of an interfering signal in order to get a lot of attenuation, several RC filters can be cascaded. Unfortunately, the impedance of one RC section affects the next. What this means is that the transition between the pass and stop bands will not be sharp. A sharp transition helps reduce the interfering signal without causing degradation to the desired signals. In this case, the Sallen-Key active filter can do the job well. This circuit uses a 2-pole filter. Cascading a number of stages can give a steep attenuation transition with a very sharp knee. This cut-off frequency aids in selecting the R20 an d R22 resistor values to be used in the low pass filter design to average noise in the DC signal 6. The required Q for the butterworth filter = 1.414. The op-amp stage is a unity gain follower when R20 = R22. if C9 and C10 are equal, then the Q = 1.5858 for Butterworth response. Using convenient near values gain of 1.56 in the formula, R20 = R22 = Q / (4 ·Ãâ‚¬Ã‚ ·fo ·C9) where, fo = cut-off frequency = 4Hz, C9 = C10 = 0.1ÃŽ ¼F R20 = R20 = 310.31kÃŽ © The nearest standard resistor value to this calcualted resistor value is 330k Voltage Controlled Oscillator A voltage-controlled oscillator is an oscillator whose frequency is determined by a control voltage. As the control voltage causes the frequency to rise slowly until it hits a maximum and then falls back to the starting frequency. The first op-amp is an integrator(U7:A). A voltage divider puts the + input at half the control voltage. The op-amp attempts to keep its input at the same voltage, which requires a current flow across the 100k to ensure that its voltage drop is half the control voltage. When the MOSFET at the bottom is on, the current from the 200k goes through the MOSFET. Since the 100k resistor has the same voltage drop as the 100k but half the resistance, it must have twice as much current flowing through it. The additional current comes from the capacitor, charging it, so the first op-amp must provide a steadily rising output voltage to source this current. When the MOSFET at the bottom is off, the current from the 200k goes through the capacitor, discharging it, so a steadily falling output voltage is needed from the first op-amp. The result of the operation of this integrator circuit is a triangular waveform confirmed by figure 13 of the appendix. The capacitance of the capacitor in our circuit is determined thus: The second op-amp is a Schmitt trigger. It takes the triangle wave as input. When the input voltage rises above the threshold of 3.33 V, it outputs 5 V and the threshold voltage falls to 1.67 V. When the input voltage falls below that, the output goes to 0 V and the threshold moves back up. The output is a square wave. Its connected to the MOSFET, causing the integrator to raise or lower its output voltage as needed 4. Figure 14 shows the graphical representation of this circuit . The variation of the supply voltage from 3V to 9V while observing the output signal frequency obtains the sensitivity of the overall voltage- controlled oscillator circuit to supply voltage. From the test observation, the VCO produced no output signal at 3Vand beyond 6.2V. The below table shows the values obtained for the during the sensitivity test of the voltage-controlled oscillator. Using the power supply sensitivity formula Sensitivity Percentage change in frequency = Percentage change in power supply voltage = Between 5V to 6V, the percentage change in power supply voltage = = 20% While the percentage change in frequency is = 3.575% VCO sensitivity to this supply voltage variation = = 17.875 % Between 4V to 5V, the percentage change in power supply voltage = = 25% While the percentage change in frequency is = 12.21% VCO sensitivity to this supply voltage variation = = 48.84% The inference from the above calculation shows that the sensitivity of this lock-in amplifier based micro-ohmmeter to power supply voltage increases with reducing supply voltage. The tuning range of the VCO refers to the range of oscillation frequencies Two important parameters in VCO design are linearity and sweep range. Linearity correlates the change in frequency or the VCO output to the change in the control voltage. The sweep range is the range of possible frequencies produced by VCO control voltage. The linearity Muting Detector Circuit The filtered output from the phase sensitive detector is a control voltage which, with Zero input ( short circuited probes) is about Vg volts . It goes more positive with increasing signal level. With maximum input(open circuited probes) the voltage will saturate near the positive supply rail. This would result in a loud high pitched tone from the oscillator, which is not what we want. We want the it to be mute when the probes are disconnected and to do this another operational amplifier is brought in to compare the control voltage with a reference voltage. Whenever the control voltage goes higher than the reference, the output will go negative. This allows a small current to be drawn through D1 and R25, which will keep the oscillator transistor switched off, stopping oscillation. The output voltage of an AM synchronous detector is compared with a reference potential level by a voltage comparator. A muting device connected with the output of the detector is controlled by a control circuit connected with the comparator. Through this control circuit, the detector output is immediately muted when the detector output level falls below the reference potential level, and the muting of the detector output is removed after a predetermined retardation when the detector output level exceeds the reference potential level.

Globalization trends

Each of these stakeholders gains when a company improves the value Hahn. The common key processes that should be used to improve the value and supply chain revolve around the customer, stakeholder, and supplier. Strategic planning to change management to customer service all serve a purpose. That purpose is to enable companies and partners to do business in such a different way that creates competitive advantage. When performance is elevated to a level in which success is imminent the company not only sees increase in profits but also sees new levels in customer service, inventory, production, and synchronization of key operations.Country Risk Analysis – Struck Entering Japan Any number of risks can affect an organization's global operations and the way to overcome these risks is by implementing advantageous strategic goals and strategies. In any new business venture a firm must take risks to achieve objectives set. When expanding into a new country a higher degree of risk mus t be taken. However, a higher degree of risk does not mean the company will be venerable to losses because of changes in the economies or political situations in countries in which they are investing.Understanding the types of risk involved and properly planning for these risks will allow the company to mitigate most problems and revert losses. As described by A. M. Best's assessment (2009) of the three categories of risk, Japan has been rated low in economic, political, and financial systems. Economic Environment Japan is the second largest economy in the world behind the United States. Yet, revised figures for the final quarter of 2009 grew by less than what was estimated, 1. 1 percent. â€Å"Japan continues to face the problem of deflation† (BBC News, 2010, Para. 6).Because deflation is bad for the economy, the tendency is for consumers and businesses to delay in making major purchases. With the value of currency rising all he higher value of currency to purchase more. Ban k of Japan board members during their February meeting had mixed views on the economy. Some members believe that upside and downside risks were becoming balanced, whereas others felt â€Å"considerable downside risks to the economy' (Toasts, 2010, Para. 2). Believing that brand recognition alone could aid in the success of expansion into Japan was not a good move for Struck.Because the Japanese have a taste for everything western Struck was sure about the marketability of the Japanese. Unfortunately, Struck suffered because of â€Å"bad predictions† (Gators, 2009, Para. 0) and not enough information gathered on Japan's economy. Political Environment Presently, Japanese Prime Minister Taro Ass is struggling to implement strategies to bolster Japan's economy. The Liberal Democratic Party (LDAP) has not passed a supplemental budget needed to fund the first economic stimulus package discussed back in October 2008 (Hashish, 2009).The political paralysis of Japan takes part in the global financial crisis causing the eroding of consumer product purchases. Once a business is up and running the worry becomes entering and enforcing contracts with errs and sellers. Even with guidelines set in formulating and enforcing contracts variations are still placed on certain ways a country views the legal system. Japan is a civil law system country encouraging shorter and less specific contracts because the general civic code deals with many pertinent issues (Daniels, Redheaded ; Sullivan, 2007).The wealth of the country decides on what business regulation procedures are required when opening a business. With free trade becoming more popular in countries that at one time placed strict regulations on foreign businesses he increase in capital has effected multinational and international companies to expand outside their home countries. The relaxed restrictions result in opportunities for people to experience global products and brands. Components of a Global Business Plan A business plan tells a story about a company's strategies and goals.Along with this information, a business plan also requires specific components. The first section must start with an executive summary. The executive summary is a brief synopsis of the business plan that includes a description of the nature of the business, a reason rodents or services is needed, description of the organization and management team, and a brief explanation on the sales and marketing approach. The next section is more detailed information taken from the executive summary including the business, market analysis, financing, and management sections.Conclusion Stakeholders can be anyone directly and indirectly associated with the company, such as customers, suppliers, employees, and shareholders. Each can benefit as well as lose. The key is making sure all activities are streamlined and work in a synchronized manner. When this happens stakeholders benefit by lower costs, new reduce design and development, and trustworthiness of the company. Economic exposure is defined as, â€Å"the extent to which a firm's market value is sensitive to unexpected changes in foreign currency' (Perry, 2009, Three Types of Foreign Exchange Exposure for Mans, Para. ). Before expanding into another country, researching the economic structure of the country is important. Economic risk comes from the inability of a country to meet financial obligations. Sustaining, and self-governing society (Daniels, Redheaded, & Sullivan, 2007, Para. 1). Creating a majority of people in society that accepts present political views an result in positive benefits including the attraction of foreign investment and international trade. When turmoil among the people and the roles of government exists, friction occur creating unpleasant unrest.

Cutting Teeth onLiterature In the perennial push to make new and over-achieving parents as paranoid as possible comes this new line of classics designed for you guessed it babies.  Baby Einstein? Pffft. Thats for all those poor children born in the last century. And besides, the claims that listening to classical music will enhance young _____________________ s (insert nom-du-jour here) intelligence proved false. So false, in fact, that consumers were refunded their money. But, like I said, it is now the twenty-first century and things are different. Now we have Baby Lit. The first two titles to be released, in board book form, are Pride and Prejudice and Romeo and Juliet. They are condensed to, I am assuming, handsome-boys-and-pretty-girls-dressed-in-primary-colors-and-smiling-a-lot. Because otherwise, a boiled-down-to-bare-essentials of Romeo and Juliet would involve a lot of yucky stabbiness. And I dont care how precocious your toddler is, two-year-olds simply cannot reliably comment on the politics of primogeniture. I have two children, aged 14 and 11, who are now top-notch readers. But when they were 0-3 years, the target audience for Baby Lit, they primarily used their board books for nomming purposes, and all were equal opportunity in the drool rotation: happy spoon, pat-able bunnies, and dump truck stories alike.  So go ahead, get a few Baby Lit titles for your diaper bag.

The Hillsborough disaster Essay Essay Example

The Hillsborough disaster Essay Essay Example The Hillsborough disaster Essay Essay The Hillsborough disaster Essay Essay The Hillsborough catastrophe was an incident that occurred on 15 April 1989 at the Hillsborough bowl in Sheffield. England. during the FA cup semi-final lucifer between Liverpool and Nottingham Forest association football nines. The crush resulted in the deceases of 96 people and hurts to 766 others. The incident has since been blamed chiefly on the constabulary. The incident remains the worst stadium-related catastrophe in British history and one of the world’s worst association football catastrophes. association football nines used to contend the semi-final of the FA Cup at a impersonal locale. and in 1989 Hillsborough was selected by the association football. While opposing protagonists were segregated in the bowl. Liverpool fans were allocated the Leppings Lane base. reached by a limited figure of turnstiles. Entry to the land was slow due to the few decrepit turnstiles available to the Liverpool fans which caused unsafe overcrowding outside the land before kick-off. In an effort to ease force per unit area outside the land. Chief Superintendent Duckenfield ordered an issue gate to be opened. The opened issue gate led to a tunnel marked â€Å"Standing† which led straight to the two already overcrowded enclosures ( pens ) . In old old ages the tunnel had been closed off by constabulary when the two cardinal pens were full. nevertheless on this juncture the tunnel was unmanned. The resulting inflow of protagonists caused suppression and some fans climbed over side fencings or were lifted by fellow protagonists onto the base above to get away the crush. Moments after kick-off. a crush barrier broke and fans began to fall on top of each other. The game was stopped after six proceedingss. To transport away the injured. protagonists tore down advertisement billboards to utilize as stretchers and exigency services were called to supply aid. Of the 96 people who died. 14 were admitted to infirmary. When the FA Chairman visited the Control Box to happen out what had happened. Chief Superintendent Duckenfield told a ‘disgraceful prevarication that the protagonists had â€Å"rushed† the gate. The 1990 functionary enquiry into the catastrophe. the Taylor Report. concluded â€Å"the chief ground for the catastrophe was the failure of constabulary control. The findings of the study resulted in the riddance of standing patios at all major football bowls in England. Wales and Scotland. On the twentieth day of remembrance of the catastrophe. authorities curate Andy Burnham called for the constabulary. ambulance and all other public bureaus to let go of paperss which were non made available to Lord Justice Taylor in 1989. This action led to the formation of the Hillsborough Independent Panel. which in September 2012 concluded that no Liverpool fans were responsible for the deceases. and that efforts had been made by the governments to hide what happened. including the change by constabulary of 116 statements associating to the catastrophe. The facts in the study prompted immediate apologies from Prime Minister David cameron ; the Chief Constable of South Yorkshire Police Chairman David Bernstein and Kelvin Mackenzie. then-editor of The Sun. for their organisations’ several functions. In September 2012. the Hillsborough Independent Panel concluded that up to 41 of the 96 human deaths might hold been avoided had they received prompt medical intervention. The study revealed â€Å"multiple failures† by other exigency services and public organic structures which contributed to the decease toll. In response to the panel’s study. Attorney General for England and Waless. Dominic Grieve MP. confirmed he would see all the new grounds to measure whether the original inquest finding of facts of inadvertent decease could be overturned. On 19 December 2012. a new inquest was granted in the High Court. to the alleviation of the households and friends of the Hillsborough deceased. 1.

Statistics 401 Mod 2 Case - Hypothesis Testing 1 Coursework

Statistics 401 Mod 2 Case - Hypothesis Testing 1 - Coursework Example Since then in the U.S. genetic engineering has expanded in various areas of food production. In 2006, among all countries of the world, United States alone grew 53% of genetically modified crop (Oak Ridge National Laboratory). The purpose of this study is to evaluate influence of GM food over non-GM food. In order to do so, this assignment has selected Tomatoes. It is claimed that genetically modified tomatoes show longer shelf lives than non-genetically modified tomatoes (Discovery). This assignment uses statistical design method to verify this claim. The design method is called hypothesis test. There are two different hypotheses; null hypothesis, and alternative hypothesis. If one hypothesis is true then the other hypothesis is false. In this design, null hypothesis is defined as Ho: The mean value of shelf lives of GM tomatoes is equal or greater than the mean value of shelf lives of non-GM tomatoes. The alternative hypothesis is defined as Ha: The mean value of shelf lives of GM tomatoes is less than the mean value of shelf lives of non-GM tomatoes. In a mathematical way, the test tends to satisfy the condition SL mean GM > = SL mean non-GM, where SL mean GM is the mean value of shelf lives of genetically modified tomatoes and SL mean non-GM is the mean value of shelf lives of non-genetically modified tomatoes. ... are less than       non-GM tomatoes non-GM shelf lives                   Hypothesis Evaluation against observations Acceptance of hypothesis Observations Ho Ha Ho Ha Test confirms null, Ho Null is TRUE Alternative is FALSE No Error Type I Error Test does not confirm null, Ho Null is FALSE Alternative is TRUE Type II Error No Error Type I error: Tomato growers do not buy GM plants and lose money from rotting tomatoes. Type II error: Tomato growers buy GM plants, which are more expensive than non-GM, but shelf lives do not increase. Tomatoes may be produced both from genetically modified or non-genetically modified plants. The study claims that shelf lives of GM tomatoes are greater than the shelf lives of non-GM tomatoes. Through statistical test it can be verified whether the distributions of shelf lives of GM and non-GM tomatoes differ from each another or not. This can be achieved through Chi-square test. The Chi-square test consists of (1) hypothesis formulation, ( 2) test design plan, (3) sample data analysis, and (4) result interpretation. The Chi-square test also assumes the following: GM tomatoes sampling is random; the population is10 times larger than the sample; the variable is categorical, and each level of the variable has at least 5 frequencies. The Chi-square study uses shelf lives values from GM tomatoes population and compares them to the shelf lives values of non-GM parameters. In Chi-square test, shelf lives of non-GM parameters are considered as expected values. The shelf lives of non-GM parameters include three levels: (1) mean value of the population, (2) greater than the mean value, and (3) less than the mean value. If the GM tomatoes do not increase the shelf lives, then the study will duplicate the non-GM results. On the contrary, if the GM

Strategic Management analysis Essay Example | Topics and Well Written Essays - 1500 words

Strategic Management analysis - Essay Example However, since the use of petroleum products began, the adoption of other forms of fuel process has been slow. With the coming of companies like Better Place, the use of electricity to replace oil has been taking root. This company is motivated by the fact that the rise use of Electric Vehicle is slow, despite the fact that these vehicles are environmental friendly. The company has its own mission and vision that refine its focus in the automotive industry. The company’s mission is to first reduce and later eventually eliminate the use and dependence of oil in automobile industry. This mission defines the company’s focus and what it does differently to create value. This is a global company captivated to creating the world a better place. It works with stakeholders in automobile industry to enhance the spread of EVs. 1.2. Vision The company’s vision is to integrate car companies with the other companies like the battery and utilities companies, and consumers in a way that will enhance an increase in the use of EVs. This vision shows the belief of the company that the only way consumers can adopt EVs in a massive way is by overcoming the main challenge behind the use of EVs, which is its mobility. This belief differentiates the company from other value creators who believed that the massive adoption of EVs will be possible only when the battery capacity is increased. This increase will help cars travel over a hundred miles that are currently possible. Therefore, the company believes that it can achieve the generating of EVs by re-engineering cars and not batteries. This is possible by working on the available technologies and involving the relevant profiles in the automobile industries (Rothaermel 2013). 1.3. Stakeholders The table below maps the stakeholders in Better Place Company Stakeholder Claims and Interests Class Investors Transport project that would have higher returns, receive positive image, and innovative. Key player Government Developing a sustainable transport system Key player Auto Manufacturers developing a sustainable transport system Key player Regulatory Bodies Receive information and regulate organization behavior Keep Satisfied Technical specialists Specify the required technologies to meet the company’s requirements Key player Customers Make successful transitions Key player Program manager Budgeting Keep Informed The government and auto manufacturers are in support of a sustainable transport system. Their failure to acknowledge EVs in some instances is a threat. Customers desire to be relieved from the high cost of oil opt for EVs. The company is interested in reducing pollution and consumption of oil. The project is vital in reducing the increasing economic costs that come with high dependency of oil in different industries including transport. To effectively address the concerns of stakeholders, the company needs to integrate the working of different stakeholders to share ideas (Abernat hy, J and Utterback 1975). In addition, customers need to be educated on the significance of EVs. Finally, the company will work to show admirable results in short period to attract more investors. 2. Industry Analysis and Scenarios 2.1. Industry Analysis Better place has can establish its strategy beyond the suppliers bargaining power. The company has numerous suppliers located in different countries who can give vehicle products and other services. In addition, the customers are located in different countries like Australia and United States of America. The main substitute for EVs is the oil. This product has received numerous criticisms regarding its emission on the environment. In a nutshell, suppliers are forced to embrace new initiatives that are environmental friendly (Thompson et al.
