...48550 Electrical Energy Technology Chapter 6. Synchronous Machines Topics to cover: 1) Introduction 2) Synchronous machine structures 3) Rotating magnetic field 4) Equivalent circuit model 5) Performance as a generator 6) Performance as a motor Introduction A synchronous machine is an ac rotating machine whose speed under steady state condition is proportional to the frequency of the current in its armature. The magnetic field created by the armature currents rotates at the same speed as that created by the field current on the rotor, which is rotating at the synchronous speed, and a steady torque results. Synchronous machines are commonly used as generators especially for large power systems, such as turbine generators and hydroelectric generators in the grid power supply. Because the rotor speed is proportional to the frequency of excitation, synchronous motors can be used in situations where constant speed drive is required. Since the reactive power generated by a synchronous machine can be adjusted by controlling the magnitude of the rotor field current, unloaded synchronous machines are also often installed in power systems solely for power factor correction or for control of reactive kVA flow. Such machines, known as synchronous condensers, may be more economical in the large sizes than static capacitors. With power electronic variable voltage variable frequency (VVVF) power supplies, synchronous motors, especially those with permanent magnet rotors, are widely used...

...home after the previous governess died. Douglas begins to read from the written record, and the story shifts to the governess’s point of view as she narrates her strange experience. The governess begins her story with her first day at Bly, the country home, where she meets Flora and a maid named Mrs. Grose. The governess is nervous but feels relieved by Flora’s beauty and charm. The next day she receives a letter from her employer, which contains a letter from Miles’s headmaster saying that Miles cannot return to school. The letter does not specify what Miles has done to deserve expulsion, and, alarmed, the governess questions Mrs. Grose about it. Mrs. Grose admits that Miles has on occasion been bad, but only in the ways boys ought to be. The governess is reassured as she drives to meet Miles. One evening, as the governess strolls around the grounds, she sees a strange man in a tower of the house and exchanges an intense stare with him. She says nothing to Mrs. Grose. Later, she catches the same man glaring into the dining-room window, and she rushes outside to investigate. The man is gone, and the governess looks into the window from outside. Her image in the window frightens Mrs. Grose, who has just walked into the room....

...character? To what extent is her final protest justified? How do the other characters portray themselves by their attitudes toward the ritual? Mrs. Tess Hutchinson stands out right from the start: she arrives at the lottery late. She explains to Mr. Summers that she was doing her dishes and forgot what day it was. The town treats her lateness lightly, but several people comment on it, “in voices just loud enough to be heard across the crowd, ‘Here comes your Missus, Hutchinson,’ and ‘ Bill, she made it after all.’” (Jackson 501). It is ironic that she is the one who wins the lottery, and is fated to be stoned. So Tess Hutchinson has already been noticed by people as one who is not entirely part of the group. Before the drawing she is friendly with the other women, pretending to be pleased to be present. The very moment that she sees is her family that draws the black dot, though, her egotism is evident. “You didn’t give him time enough to take any paper he wanted. I saw you. It wasn’t fair!” (Jackson 504). She continues to scream about the unfairness of the ritual up until her stoning. Mrs. Hutchinson knew the lottery was wrong, but she never did anything about it. She pretends as much as she could to enjoy it, when she truly hated it all along. Maybe Jackson is suggesting that the more hypocritical one is, the more of a target they are. Mrs. Hutchinson was clearly the target of her fears. I think sometimes we have no problem remarking on people’s adultery until it is ourselves that...

...May I beg that you will write at once to the mother of this unfortunate woman--to Mrs. Catherick--to ask for her testimony in support of the explanation which I have just offered to you?" I saw Miss Halcombe change colour, and look a little uneasy. Sir Percival's suggestion, politely as it was expressed, appeared to her, as it appeared to me, to point very delicately at the hesitation which her manner had betrayed a moment or two since. I hope, Sir Percival, you don't do me the injustice to suppose that I distrust you," she said quickly. "Certainly not, Miss Halcombe. I make my proposal purely as an act of attention to YOU. Will you excuse my obstinacy if I still venture to press it?" He walked to the writing-table as he spoke, drew a chair to it, and opened the paper case. "Let me beg you to write the note," he said, "as a favour to ME. It need not occupy you more than a few minutes. You have only to ask Mrs. Catherick two questions. First, if her daughter was placed in the Asylum with her knowledge and approval. Secondly, if the share I took in the matter was such as to merit the expression of her gratitude towards myself? Mr. Gilmore's mind is at ease on this unpleasant subject, and your mind is at ease—pray set my mind at ease also by writing the note." "You oblige me to grant your request, Sir Percival, when I would much rather refuse it." With those words Miss Halcombe rose from her place and went to the writing-table. Sir Percival thanked her, handed her a...

...He went to where Miss Mijares sat, a tall, big man, walking with an economy of movement, graceful and light, a man who knew his body and used it well. He sat in the low chair worn decrepit by countless other interviewers and laid all ten fingerprints carefully on the edge of her desk. She pushed a sheet towards him, rolling a pencil along with it. While he read the question and wrote down his answers, she glanced at her watch and saw that it was ten. "I shall be coming back quickly," she said, speaking distinctly in the dialect (you were never sure about these people on their first visit, if they could speak English, or even write at all, the poor were always proud and to use the dialect with them was an act of charity), "you will wait for me." As she walked to the cafeteria, Miss Mijares thought how she could easily have said, Please wait for me, or will you wait for me? But years of working for the placement section had dulled the edges of her instinct for courtesy. She spoke now peremtorily, with an abruptness she knew annoyed the people about her. When she talked with the jobless across her desk, asking them the damning questions that completed their humiliation, watching pale tongues run over dry lips, dirt crusted handkerchiefs flutter in trembling hands, she was filled with an impatience she could not understand. Sign here, she had said thousands of times, pushing the familiar form across, her finger held to a line, feeling the impatience grow at sight of the man...

...Article 86 of the Uniform Code Of Military Justice. This Article covers Point and Place of Duty. That means from PT formation to COB that is where you will be. What a lot of Soldiers do not understand that includes appointments made by them or someone else. We have appointment times, SP times, formation times and many other start times that dictate we will be there. If a Convoy has an SP time of fifteen hundred hours and the Soldiers decide to show up late because they did not feel like getting ready on time people could die. If they rolled out on time, they may have avoided the ambush or avoided the Vbid that hit them in the bottleneck. It sounds extreme but time management plays a critical role in the Army. When you make an appointment that spot has been reserved for you. That means if you have been given the last slot someone else is going to have to wait for another one to open up. This could be one day or one month. And because you missed it someone else is still going to have to wait when they could have had that spot and been there. If you are going to miss the appointment or cannot make it due to mission they do allow us to cancel the appointment with in twenty four hours. The Army allows us to make appointments for whatever we need. Be it for a medical appointment, house goods, CIF, Smoking Sensation or whatever we need these recourses are available to us. But when Soldiers start missing appointments theses systems start to become inefficient. What a lot of Soldiers do...

Nearly 7 million residents are related to Cantonese ethnic groups,called ‘’Hakka’’and‘’Chiu Chow’’. The society of Hong Kong suffers from an aging population due to the declining birth rate. Particularly, the fertility rate dropped to 1.09 in 2012, indicates the ratio below the replacement rate of 2.1.Simultaneously, life expectancy remains elevated ,and is planned to attain 82 for men and 88 for women by 2031. Hong Kong’s old age dependency rate is expected to enlarge and to exceed Japan by 2060. Language According to the 1996 census, the official languages are Chinese and English, about 3.1% of Hong Kong citizens claimed English as the language of everyday communication and nearly 34.9% identified English as a second language.(Bolton,2000) Despite the ended British governance in 1997, Western culture is deeply entrenched in the country and harmonious with the conventional traditions and Eastern philosophy.(Buckley,1997).

...Improving Organizational Performance Kenyetta PYSCH/ 428 May 06, 2013 Marianne Narick Improving Organizational Performance Organizations prove successful by the business structure, communication with employees and job satisfaction. There are many ways to accomplish such goals with team building strategies and communication. According to www.boundless.com, “Job satisfaction can be influenced by a person's ability to complete required tasks, the level of communication in an organization, and the way management treats employees. It isn't always easy to measure job satisfaction as the definition of satisfaction can be different for different people. If an organization is concerned about job satisfaction of their employees, management may want to conduct surveys to determine what type of strategies to implement”. Airdevils Inc, is an aerial stunts performance facility in Salt Lake City, Utah. The company was founded in 1995 by one of the best female stunt performers, Celsey Evans and five other performers of the same expertise. By the next year, Airdevils’ workforce expanded to 115 crew members. With a thriving business and company workforce expansion, the founding partners retired from stunt performances and formed the top management staff. For the past two years business came to a stand-still existing and new customers not impressed with the stunts, key employee turnover was at an all-time high and to top things off current employee job satisfaction low.
