Employees Motivation of Ernst & Young in Malaysia

Employees Motivation of Ernst & Young in Malaysia The purpose of this research is to study the factors that affect the motivation of Ernst Young employees in Malaysia branches. Also explore how these motivation theories influence Ernst Young to its employees and be able to recommend new motivational programs to the management that will improve the current motivational practices of the employees. Objectives: To identify the motivational factors that motivate Ernst Young employee To investigate how Maslow Hierarchy Theory affect the motivation To understand the important reasons why employees retain or leave in the company and how motivation theories have emerged in attract talent employees To find out the role of leadership and management in motivating employee in Ernst Young Research Question: How the effects of compensation/salary and rewards to employee motivation? How does teamwork affect work performance and motivation? How do achievement and recognition affect motivation and job satisfaction? Introduction: Motivation is define as The willingness to exert high levels of effort toward organizational goals, conditioned by the efforts ability to satisfy some individual need (Stephen P. Robbins, 1998). On the other hand, employee motivation is defined psychological forces that determine the direction of a persons behavior in an organization, a persons level of effort and a persons level of persistence (Gareth R, Jennifer M GEORGE Charles WL HILL, 2000). Employee motivation is a key to the overall effectiveness of an organization. In the Maslows Hierarchy of Needs consists of five different levels, which included physiological, safety, social, esteem and self-actualization. This theory explains that employees at organizations are motivated by the desire to achieve or maintain the various conditions upon which these basic satisfactions rest and by certain more intellectual desires (Maslow, 1943). If a lower level need is not met, the person is less motivates to attend the higher level needs until it has been satisfied. While the expectancy theory attempt to explain workers motivation in terms of rewards. This theory assumes that people make rational decisions based on economic realities (Kreitner, R., Kinicki, A., Cole, N., 2003). According to V. H. Vroom suggested that people on purposely choose particular courses of action, based on perceptions, attitudes, and beliefs, as a consequence of their desires (V. H. Vroom, 1964). In other words, Expectancy theory is emphasizes on individual perceptions of the surroundings and connections arising as a consequence of personal expectations. At the present, compensation is necessary to employee motivation. If a company can satisfied an employee financial needs, the employee would naturally be motivated to work harder. Besides that, leadership also affects employee motivation. A successful leader has a different view in the chain of command. He recognizes the importance of influencing the follower gently towards a desired goal (Miller, 1996). He does not force or pushed the followers to accomplish the goal of the organization (Maccoby, 1996). Company Background: Ernst Young is recognized as one of the largest professional services firms in the world and global organization of member firms in more than 140 countries (Ernst Young, 2010). Its international headquarters are located in London, UK and New York, US. Currently the company surrounded of 144,000 employees globally (Ernst Young, 2010). Ernst Young Malaysia was established in 1909 and it was one of the first internationally linked public accounting firms in the country (Ernst Young Malaysia, 2010). In 2002, one of the first Bumiputra accounting firm in Malaysia founded by Hanafiah, Raslan Mohamad in 1964 are became a member firm of Ernst Young. Ernst Young is now the largest professional services firms with more than 2,300 employees in 17 offices in West and East Malaysia (Ernst Young Malaysia, 2009). Ernst Young Malaysia is a market leader in the provision of assurance and advisory business services, tax and transaction advisory services, serving a board array of clients, cov ering all industries and market segments. Significance of Study: This research aims is to conduct research and examine the current factors that motivates the employees in Ernst Young Malaysia. Besides that, this project also explore the factor influencing work motivation and job satisfaction for getting better performance and high productivity. The essence of that approach is to create basic conditions regarding changing job characteristics that promote high performance motivation, high satisfaction at work and match the job with the individual. Literature Review: Previously employees were considered just another input into the production of goods and services in the organization point of view (James R. Lindner, 2010). Nevertheless the Hawthorne Studies has changed the way for organization to think about the employees (Elton Mayo, 1924 to 1932). These studies found out that monetary needs do not motivate employees toward full potential, but it is the employee attitudes and behavior (Elton Mayo, 1924 to 1932). To better understand the employees motivation, management has to realize the whole concept of motivation. There are many motivation theories developed by the researches and theorists examine on what motivated employees and how they were motivated. The most fundamental theory of motivation is Maslows Hierarchy of Needs. And it has become one of the most popular and frequently cited theories of human motivation. The theory consists of five different levels, which are physiological, safety, social, esteem and self-actualization. This theory explains that employees at organizations are motivated by the desire to achieve or maintain the various conditions upon which these basic satisfactions rest and by certain more intellectual desires (Maslow, 1943). According to Abraham Maslow, the most basic needs are physiological. Physiological needs are refer to those that sustain physical life, such as the need for food. Subsequently are safety needs, the want for physiological safety such as shelter. Next is a social need, is the need for friendship, social and love. In the need for self-esteem is referring to accomplish self-respect or to feel that one is  worthwhile and successful. Finally, there self-actualization is for self-fulfillm ent and to achieve all that one is potentially capable of. These two growths need to drive the person to want recognition from others, development, challenge, and the freedom to be creative and innovative. Daniels (2001) recommended that Maslows final conclusion that the self-actualization is inspiring in their nature may be one of his most important contributions to the study of human behavior and motivation (Daniels, 2001). There are several studies that have been concluded based on Maslow hierarchy to support the suggestions of William James (1892/1962) and Mathes (1981). William James theorized the levels of material, social, and spiritual. While Mathes proposed the three levels were physiological, belonginess, and self-actualization. Nevertheless he considered safety and self-esteem as unnecessary. In addition, Alderfer (1972) has developed a similar hierarchy with his ERG theory, which included Existence, Relatedness, and Growth. He adapted Maslows theory based on the effort of Gordon Allport (1960, 1961) who integrated concepts from systems theory into his work on personality. The expectancy theory assumes that people make rational decisions based on economic realities (Kreitner and Kinicki, 1998). Vaida (2003) claimed that incentives used to reward excellent performance and in work processes. Additionally, Hoy and Miskel (1991) agree that incentives such as money, power, as well as general incentives that are non-material. Acoording to V. H. Vroom (1964) suggested that people intentionally makes certain courses of action, based on their perceptions, attitudes, and beliefs, as a consequence of their desires (V. H. Vroom, 1964). In other words, Expectancy theory is emphasizes individual perceptions of the environment and subsequent interactions arising as a consequence of personal expectations (V. H. Vroom, 1964). These theories on the other hand are motivation theories that focus o n the internal attributes of the individual. Caruth Handlogten (2001) claimed that compensation can enhance the employee motivation. Compensation may refer to monetary or non-monetary, tangible or intangible, and physical or psychological, and these are offered to the employees for more productivity (Caruth Handlogten, 2001). If a company can satisfied an employee financial needs, the employee would naturally be motivated to work harder. However paying an employee will not retain them for a long period in the organization. To retain an employee and to keep him motivated and inspired, an employee must be empowered (Bratton, 1999). Empowered allows employee feels the ownership of business and make decision on their own which can increase its confidence by enhancing decision making power (Bratton, 1999). In the recent research from Watson Wyatt Worldwide, recommends that to attract the greatest employees, companies need to pay more than the average-paying in the market (Ira Kay and Bruce Pfau, 2001). Money provides most basic em ployees motivation. The leadership style of the managers also is important to implementation of the motivation programs. Quantitative studies conducted in the past showed positive relationship between leadership behavior and job satisfaction (Euske et al, 1982; Savery, 1994). A Managers leadership style contributes directly to the employees motivation and work satisfaction, and the work progress in the organization. A successful leader has a different view in the chain of command. He recognizes the importance of influencing the follower gently towards a desired goal (Miller,  1996). He does not force or pushed the followers to accomplish the goal of the organization (Maccoby, 1996). McConnell (1998) suggests that leader should spend more time to get to know his followers better. Leaders should pay attention to details regarding on their followers. Methodology: There are four major components apply into this research and shows its relationship to the employee motivation. This research consists of only 5 variables. The dependant variable would be Employee Motivation and the independent variable is included Maslow Hierarchy, Expectancy Theory, Compensation and Leadership Management. The theoretical framework for this research as bellow: Maslow Hierarchy Expectancy Theory Employee Motivation Compensation Leadership Management INDEPENDENT VARIABLE DEPENDENT VARIABLE The research method is qualitative for this study by a survey method. The total population of employees in Ernst Young Malaysia is 2300 in 2009. Further research will conducted to identify the present population. However, the target population for survey is all employees on the all the 17 office. In the data collection process, primary data is using to accomplish in this research. Employees will be sampled through convenience sampling in this research. So of the employees who do not want to participate in the study will be subtracted from the 100% original samples. A structured questionnaire will be designed for the purpose of this research. The questionnaire will contain 30 questions that would help identify the motivating factors of employees in Ernst Young.

The Record Companies Decrease in Sales :: Music

The Record Companies' Decrease in Sales The music business is experiencing a recession where record sales are reaching all-time lows. All record companies have in the last few years experienced a considerable decrease in sales. Finding the cause or causes of this has naturally become a major concern for all of them. Some blame the recession in the West in general, but that can hardly explain why one industry is losing out so much more than others. Music today is less from the heart than it used to be only ten years ago. It is mostly a purely commercial product to be used up and thrown away. A lot of modern music has a short but intense life span. People are not prepared to pay as much for a 'disposable' product as they are for a 'reusable'. The hit song of the week is fed to us all through radio and TV so intensely that we need not buy the record. And when it is no longer broadcasted no one remembers it. Attempts to change this and promote more quality, depth and originality in music have not been very successful. The whole entertainment business is ruled by trends and, quality seems to have gone out of style To simply lower the price of a CD is a commonly suggested solution, naturally advocated by the buyers. But no business favors such a remedy. Not only since it reduces their income but also because it sends out the wrong signals to people. It gives the impression that the product is worth less and that the customers have been charged too much before. And if the price can drop by ten per cent this year people might expect it to drop another ten per cent next year. A better settlement could be enhancing the product and giving people more for their money. Thanks to modern technology there can be so much more included on a CD than just music. A computer with a CD-ROM drive, which is becoming quite common, allows us to read several different kinds of information off a CD. A short interview with the artist or 'behind the scenes' features can be included as so called 'Quicktime movies'. Lyric sheets, discographies, extensive biographies and even sheet music can also be added easily. Text files have such small memory requirements compared to sound that the Bible can be stored in less space than a normal length song! There have already been several Cds released which include a

Shakespeares Othello - Desdemona in Othello Essay -- Othello essays

Desdemona in Othello  Ã‚        Ã‚  Ã‚   In William Shakespeare’s tragic drama Othello, the wife of the protagonist is Desdemona. She is a lovely, intelligent, wholesome and pious person. This essay will analyze her.    In Act 1 Scene1, Iago persuades the rejected suitor of Desdemona, Roderigo, to accompany him to the home of Brabantio, Desdemona’s father, in the middle of the night. Once there the two awaken him with loud shouts about his daughter’s elopement with Othello. In response to Iago’s vulgar descriptions of Desdemona’s involvement with the general, Brabantio arises from bed and, with Roderigo’s help, gathers a search party to go and find Desdemona and bring her home. The father’s attitude is that life without his Desdemona will be much worse than before:    It is too true an evil: gone she is;   Ã‚  Ã‚  Ã‚   And what's to come of my despised time   Ã‚  Ã‚  Ã‚   Is nought but bitterness. (1.1)    So obviously the senator has great respect for his daughter, or at least for the comforts which she has afforded him up the beginning of the play. This respect is shared by her new husband Othello, who says to Iago    that I love the gentle Desdemona,   Ã‚  Ã‚  Ã‚   I would not my unhoused free condition   Ã‚  Ã‚  Ã‚   Put into circumscription and confine   Ã‚  Ã‚  Ã‚   For the sea's worth. (1.2)    Once that Brabantio has located Othello, the father presses charges publicly in order to have Desdemona returned:      Ã‚  Ã‚  Ã‚   To prison, till fit time   Ã‚  Ã‚  Ã‚   Of law and course of direct session   Ã‚  Ã‚  Ã‚   Call thee to answer. (1.2)    The proceedings which take place before the Duke of Venice cause the father to permanently lose his daughter, mostly due to Desdemona’s own fluent presentation of her point of view in the city... ...he was heavenly true!† And upon the arrival of Iago, she publicly accuses him of lying:      Ã‚  Ã‚  Ã‚   You told a lie, an odious, damned lie;   Ã‚  Ã‚  Ã‚   Upon my soul, a lie, a wicked lie.   Ã‚  Ã‚  Ã‚   She false with Cassio! (5.2)    Then she accuses him of causing murder: â€Å"And your reports have set the murder on.† Emilia’s stunning interrogation and conviction of her own husband as the evil mastermind behind the murder results in Iago’s murder of her. Gullible Othello, grief-stricken by remorse for the tragic mistake he has made, stabs himself and dies on the bed next to his wife, his sorrow being as deep as his love for Desdemona prior to Iago’s machinations.    WORKS CITED    Shakespeare, William.

A day in a Cave in the Rocky Mountains Essay

The soft morning breeze blew over the peaks and through the tall fragrant evergreen forest. Just outside the small mountain town of Idaho Springs, Colorado on a warm mid-summer morning back in 1991 I stood on my porch watching the wildlife busily starting the day. I stepped back into my little trailer house and picked up the land line and dialed the Hunt brothers’ number. Dan picked up the phone with a cheery â€Å"Hello.† â€Å"Hey bud† I said, â€Å"are you and Devan ready to head out on this weeks spelunking adventure?† He laughed loudly and replied â€Å"We’ve been waiting for you. Let’s go.† â€Å"Okay,† I stated â€Å"I will meet you two at the bottom of the hill in fifteen minuets† and we hung up. I got my things together and hustled out the front door. I heard barking up the hill behind the house and called â€Å"Coda come.† And my four-legged Chow-mix buddy came charging down the hill full of vibrancy and joy. Coda and I walked on down the road and met up with Dan and Devan at a clearing on the other side of Clear Creek, which was the local river that eventually furnished the Coors brewery in Golden. The four of us headed up the hill through a valley to a tailing pile that laid in front of the entrance that awaited us. See more:  Perseverance essay The entrance beckoned our arrival with a musty damp scent from years of still life in darkness. We had explored this mine a few times before and found it to be the biggest one accessible to adventurers like us needing to fulfill our desire of adrenalin brought on by the many aspects of danger that lie within. Coda led the way and I carefully ducted through the low overhead opening of rock and stone that was the entry to the bowels of this mountain. The feeling of the cool damp air on my exposed skin ran a shiver down my spine as I moved forward leaving the morning sun and safety of the outside world behind. The sound of crushed rocks under our feet echoed off the solid stone walls stretching far into the distance before fading away in silence. After about 200 feet the passageway turned to the left and the day light from the outside was lost. With the flick of a switch my three-cell Mag-Light broke the darkness and the sparkle of mica and pyrite reflected off the narrow walls and ceiling. In previous journeys through this mine we had found and traveled several levels and what seemed like miles of tunnels. Coda  was leading the way and every once in awhile I would call him, â€Å"Coda come.† And a moment later his soft brown eyes would reflect in the glow of our flashlights. After about 30 minutes of travel we came to the main shaft that led to the upper levels, It was about fifteen feet in diameter and had an old wooden ladder on the left side with its rugs full of crushed rock from years of deteriation and on the right side was a chute that ore from the upper levels was dropped down and loaded into the ore cars then taken out of the mine. We decided to take a water and smoke break here and sat ourselves down on the cool rocky floor in a small circle. Dan pulled out the water bottle, took a drink and passed it around while following our traditions I lit a candle and placed it in the middle of our circle. Devan then pulled out a joint and Dan’s Bic-lighter flicked as he lit up the joint and we passed it around heightening our experience with the mind altering effects of natures own. We absorbed the stillness hearing only our own breathing and the rustle of Coda’s feet investigating the tunnel around the next corner ahead. It wasn’t long and I became aware that I could no longer hear the noises of Coda up ahead. I called out his name, â€Å"Coda† waited a moment for the sound of his paws coming down the tunnel but in return all we heard was the sound of a few stones falling and a splash. We all looked at each other in the glimmer of the candle light with the same thought. Ahead in that tunnel there was a large hole in the stone floor going down too far to see with a light. It was one of the few spots we had not ventured yet because on a previous tunnel quest we had tossed some rocks down and after watching them bounce their way down beyond the reach of the lights we heard the splash of water from below. The light of the candle was overwhelmed then extinguished as our flashlights came to life and we moved toward the hole to a lower un-traveled existence. I called for Coda again after we rounded the second corner where the cavern opened up wider, about twenty feet wide by ten feet high and there was merely a two foot wide ledge that gave access to the tunnel ahead. The rest of the ground gave way to what looked liked the throat of Hell ready to swallow its victims. What I feared was true and we could hear from below the whimpering of a  scared friend. I shined my light down the hole and to my hearts content I could see the small figure of Coda just at the last reach of my light. Behind me I heard the sound of a zipper as Devan got into the back-pack and pulled out a rope that was always kept in our survival bag. One end of the rope was tossed to Dan and he quickly tied it to one of the ore car tracks running along the floor. We all knew that this time in this mine we would see what lied beyond our view. Devan tossed the other end down the shaft and when it reached Coda he tried to catch it like a bone, lol. I called down to Coda to ensure him I was on my way down. Then I grabbed the rope in my hands turned around and began a decent down the hole as Dan shown his light below me so I could see where I was stepping. After the first hundred feet the degree of decent decreased and I was able to release one hand off the rope without slipping down to join Coda. I turned my light back on and shown it in Codas direction and another 30 feet away he was excitingly hopping up and down like a lottery winner. I moved closer towards him and when I reached the 3 foot ledge that kept him at bay from jumping on me I hopped down and praised, and cuddled him in a loving nurturing way â€Å"You are such a brave dog† I told him. Devan called down inquiring as to the plan and I hollered back that everything was ok but I would need some help getting Coda back up. Devan started carefully back stepping down the shaft and I decided I would take a quick look around. This was the level we never seen so no since in wasting the trip. The tunnel was about three feet wide by six foot tall. The walls were very damp and the splash we heard was a stream of orange rusty water running right down the middle of the floor. Devan reached the bottom and I directed his attention toward the liquid rust flowing on the floor and the view of the unexplored tunnels in both directions. Our thoughts were on the same path as usual and we called up to Dan telling him to grab the bag, he had to see this! Upon his arrival we made a mutual decision to travel to the right, the direction the flow was coming from. We followed the flow about 70 feet till the tunnel ended abruptly. The sight at the end was something we had never seen before. The whole back wall was covered with an orange, brown and black buildup that looked like it was oozing out of the wall. From the  ceiling there were stalagtites of iron rust hanging down, some of them all the way to the floor. Water dripped from the ends of each of them and a stream came from out of the wall and flowed evenly over the rusty buildup there. We took a couple pictures of this unique and different scene that was in front of us. We poked around there for a few and turned down the other way to see where this flow of water was headed. As we passed our rope leading back up the shaft the flow path of water widened on the cavern floor gradually from the 12 inches to 18 inches and 50 feet further it covered the entire floor. We stood there a moment looking down at our boots submerged in the water past our toes. The decline was gradual and within another 100 feet the water was up to our ankles and rising. Coda stayed behind not wanting to get in the water, and 50 feet further we were knee deep in water. Again we all thought the same and decided that we wouldn’t go any further with out our inflatable raft and it was time to conclude our adventure and return ourselves to the reality of the outside world and allow the sun to shine upon our skin again. When we got back to the rope and Coda was anxiously waiting to get out so we daisy chained our way back up the shaft, pushing and pulling on him till we crested the top and pulled our little friend over the edge. After a short rest and the re-coiling of the rope I led the way back toward the outside world. We halted at the main shaft going to the upper levels were there was another opening on the side of the mountain but with careful consideration the decision was made that we had had enough adventure for one day and we should just head out the way we came. Around the last bend the afternoon sun burst into view and Coda was making a break for it. I stepped out into the hot afternoon sun and looked to the clear blue sky. I thanked God for keeping us all safe one more time. When Dan and Devan came out we headed down the hillside trailing behind Coda till he spotted a rabbit and took off after it. We never made it back down to that lower level to sail forward and see where it led because soon after that trip something happened in that cave and the county department had blocked off both entrances and posted no trespassing signs on them. It’s been awhile now since I’ve made the opportunity to travel back to that community and indulge in a spelunking  adventure, but I to keep in touch with the Hunt brothers via land line and again someday soon, I will make the time to experience that thrill again.

Automatic Room Light Controller with Didirectional Visitor Counter

CHAPTER :- 1 Project Overview 1. Introduction Of Project 1. 1 Project Definition: Project title is â€Å"AUTOMATIC ROOM LIGHT CONTROLLER WITH BIDIRECTIONAL VISITOR COUNTER â€Å". The objective of this project is to make a controller based model to count number of persons visiting particular room and accordingly light up the room. Here we can use sensor and can know present number of persons. In today’s world, there is a continuous need for automatic appliances with the increase in standard of living, there is a sense of urgency for developing circuits that would ease the complexity of life.Also if at all one wants to know the number of people present in room so as not to have congestion. This circuit proves to be helpful. 1. 2 Project Overview This Project â€Å"Automatic Room Light Controller with Visitor Counter using Microcontroller is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room v ery accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one.The light will be only switched OFF until all the persons in the room go out. The total number of persons inside the room is also displayed on the seven segment displays. The microcontroller does the above job. It receives the signals from the sensors, and this signal is operated under the control of software which is stored in ROM. Microcontroller AT89S52 continuously monitor the Infrared Receivers, When any object pass through the IR Receiver's then the IR Rays falling on the receiver are obstructed , this obstruction is sensed by the Microcontroller CHAPTER :- 2 BLOCK DIAGRAM AND ITS DESCRIPTION 2. 1Basic Block DiagramEnter Exit Relay Driver A T 8 9 S 5 2 Signal Conditioning Exit Sensor Enter Sensor Light Signal Conditioning Power Supply Fig. 2. 1 Basic Block Diagram 2. 2 Blo ck Diagram Description The basic block diagram of the bidirectional visitor counter with automatic light controller is shown in the above figure. Mainly this block diagram consist of the following essential blocks. 1. Power Supply 2. Entry and Exit sensor circuit 3. AT 89S52 micro-controller 4. Relay driver circuit 1. Power Supply:- Here we used +12V and +5V dc power supply. The main function of this block is to provide the required amount of voltage to essential circuits. 12 voltage is given. +12V is given to relay driver. To get the +5V dc power supply we have used here IC 7805, which provides the +5V dc regulated power supply. 2. Enter and Exit Circuits:- This is one of the main part of our project. The main intention of this block is to sense the person. For sensing the person and light we are using the light dependent register (LDR). By using this sensor and its related circuit diagram we can count the persons. 3. 89S52 Microcontroller:- It is a low-power, high performance CMOS 8-bit microcontroller with 8KB of Flash Programmable and Erasable Read Only Memory (PEROM).The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the MCS-51TM instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic hip, the Atmel AT89S52 is a powerful Microcontroller, which provides a highly flexible and cost effective solution so many embedded control applications. 4. Relay Driver Circuit:- This block has the potential to drive the various controlled devices.In this block mainly we are using the transistor and the relays. One relay driver circuit we are using to control the light. Output signal from AT89S52 is given to the base of the transistor, which we are further energizing the particular relay. Because of this appropriate device is selected and it do its allott ed function. CHAPTER :- 3 SCHEMATIC DIAGRAM Transmission Circuit:- Fig. 3. 1 Transmitter circuit Receiver Circuit:- Fig. 3. 2 Receiver circuit * CIRCUIT DESCRIPTION: There are two main parts of the circuits. 1. Transmission Circuits (Infrared LEDs) 2. Receiver Circuit (Sensors) . Transmission Circuit: Fig. 3. 3 Transmitter circuit This circuit diagram shows how a 555 timer IC is configured to function as a basic monostable multivibrator. A monostable multivibrator is a timing circuit that changes state once triggered, but returns to its original state after a certain time delay. It got its name from the fact that only one of its output states is stable. It is also known as a ‘one-shot'. In this circuit, a negative pulse applied at pin 2 triggers an internal flip-flop that turns off pin 7's discharge transistor, allowing C1 to charge up through R1.At the same time, the flip-flop brings the output (pin 3) level to ‘high'. When capacitor C1 as charged up to about 2/3 Vcc, t he flip-flop is triggered once again, this time making the pin 3 output ‘low' and turning on pin 7's discharge transistor, which discharges C1 to ground. This circuit, in effect, produces a pulse at pin 3 whose width t is just the product of R1 and C1, i. e. , t=R1C1. IR Transmission circuit is used to generate the modulated 36 kHz IR signal. The IC555 in the transmitter side is to generate 36 kHz square wave. Adjust the preset in the transmitter to get a 38 kHz signal at the o/p. round 1. 4K we get a 38 kHz signal. Then you point it over the sensor and its o/p will go low when it senses the IR signal of 38 kHz. 2. Receiver Circuit: Fig. 3. 4 Receiver circuit The IR transmitter will emit modulated 38 kHz IR signal and at the receiver we use TSOP1738 (Infrared Sensor). The output goes high when the there is an interruption and it return back to low after the time period determined by the capacitor and resistor in the circuit. I. e. around 1 second. CL100 is to trigger the IC555 which is configured as monostable multivibrator. Input is given to the Port 1 of the microcontroller.Port 0 is used for the 7-Segment display purpose. Port 2 is used for the Relay Turn On and Turn off Purpose. LTS 542 (Common Anode) is used for 7-Segment display. And that time Relay will get Voltage and triggered so light will get voltage and it will turn on. And when counter will be 00 that time Relay will be turned off. Reset button will reset the microcontroller.

Dip trace is a circuit designing software. After completion of the designing circuit I prepared the layout. Then I programmed the microcontroller using KEIL software using hex file. Then soldering process was done. After completion of the soldering process I tested the circuit. Still the desired output was not obtained and so troubleshooting was done. In the process of troubleshooting I found the circuit aptly soldered and connected and hence came to conclusion that there was error in programming section which was later rectified and the desired results were obtained. . 2 List of Components: Following is the list of components that are necessary to build the assembly of the Digital Speedometer Cum Odometer: * Microcontroller – AT89S52 * IC – 7805 * Sensor – TSOP 1738 (Infrared Sensor) * Transformer – 12-0-12, 500 mA * Preset – 4. 7K * Disc capacitor – 104,33pF * Reset button switch * Rectifier diode – IN4148 * Transistor – BC 547, CL 100 * 7-Segment Display 4. 3 Description of Components 4. 3. 1 Microcontroller AT89S52: The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory.The device is manu factured using Atmel’s high-density nonvolatile memory technology and is compatible with the Industry-standard 80C51 instruction set and pin out.

Environmental Pollution Essay

Los Angeles, California have been experiencing a growing population within our city. The growing population in this city has caused an increased pressure on the infrastructure and natural resources that are beginning to affect our environment. The expansion of the city has cut deeper into the rural areas that are causing problems to the environment, such as a loss in our wetlands, water pollution, biological habitats, and air pollution. The cause of the growing population has led to a high density of factories, automobiles, and commercial enterprises in Los Angeles. The population growth is beginning to create many environmental problems that are giving Los Angeles economic, and environmental consequences. Theresa Carter, an associate-level environmental scientist, has suggested four measurements of the city council for addressing the pollution management. She has suggested to Encouraging alternative transportation, walking, and bicycle use, Promoting fuel-efficient cars, Improving roads, and Encouraging carpooling. The encouragement of alternative transportation is great on the earth environment and the health of human beings. The improvement of better roads can also improve the transportation of people, reduce cars accidents, and can allow people to compost what was used. Compost helps improve soil, so it holds more water and plants grow better. Carpooling is a very effective climate change, because it allows one car to be used to carry different people to work and other places. For instance, eight people wanted to drive their car from Los Angeles to Apple valley. Los Angeles is an hour and a half drive away. Instead of using eight different cars and spending money on  eight different fossil fuels to fuel their cars, one person can use a van to carry all the co-worker to one location saving, hundreds of dollars and used of savable fossil fuels. When people use walking, bicycling, and carpooling at least twice a week it can cut the greenhouse gas emission at 1,600 pound per year. The promotion of fuel efficient vehicles allows the waste of fuel not to be used and helps protect the future cost of fossil fuels. When humans trade a car for a bicycle, it do not only improve their and the ecosystem health, It allows humans to fight obesity and rely on other ways to get around. Some persons may argue that fuel efficient cars are a great expense, but it can also be a significant improvement to get their health in order. It can do this by removing pollution from the air and gathering into their lungs. Bicycling is exercise, and many people have become obese by sitting around and driving, while not doing nothing to benefit their health. Pedestrian crashes are more than twice as likely to occur in areas without sidewalks; streets with â€Å"sidewalks on both sides have the fewest crashes. â€Å"Streets without safe places to walk, cross, catch a bus, or bicycle put people at risk. Over 5,000 pedestrians and bicyclists died on U.S. roads in 2008, and more than 120,000 were injured† (Reynolds, C, p. 22, 2009). Improvements of new roads and fuel efficient cars can be a massive expense, but the is an excellent conservation of people lives, and deter of greenhouse gases being released. Better decision making on environmental issues, allow people to make a better decision to live life on earth for a longer existence. The way the Earth works is to create and recreate, not for human to produce and destroys nature natural habitat. The following quote â€Å"Decision-making about environmental issues necessitates the maintenance of a good balance between the effectiveness of measures and the public reaction towards them.† In Theresa opinion mean that if human makes a valid decision on the thing that he or she find necessary, meaning something they can not live without Only then will they know how to keep the earth and its environment clean, and the general will began to follow. When the public sees the response of them destroying the environment personally, they can take the appropriate measure it take to have others combined with the contribute to restoring and  maintain a clean environment. Los Angeles economic and environmental hazard can become improved by encouraging alternative transportation, walking, and bicycle use, promoting fuel-efficient cars, improving roads and encouraging carpooling. Many hazards come from the emission of fossil fuels from the engines of cars, by implementing the use of people not using their cars or making fuel efficient vehicles, it helps improve the inconvenience use of vehicles. When the growth of population becomes larger, more people require unnecessary materialistic items, like cars, technology, and material that cut into the field and push down trees from growing. Animals start to get pushed out their habitats, and the earth begin to become small on their environmental structure. If Los Angeles complete or clean up their street, it may cost a profit, but it is a reduction in car accidents, better bicycling paths for bicyclist, and a cleaner environment so humans can respect and take care.

“How My Brother Leon Brought Home a Wife” by Manuel E. Arguilla Essay

Baldo and his older brother Leon were both waiting for their visitor riding a carratela. When Baldo sa his older brother’s wife, who is Maria, he was amazed by her beauty as he narrates their journey to their home in Nagrebcan. Maria was felt a bit anxious because of meeting Leon and Baldo’s parents for the first time, but along their way home, she discovered the differences of the life of the people lived there and the life in the city where she met and fell in love with Leon. Characters Leon/Noel – Maria’s husband, older brother of BaldoMaria – Leon’s wife Baldo – Leon’s younger brother, also the narrator of this story Mother and Father of Leon and BaldoAurelia – Leon and Baldo’s younger sister Labang – the carabaoSetting Nagrebcan, Bauang La Union Plot Leon and Baldo waited for the arrival of Maria at the barrio. Maria was afraid that she will not be accepted by Leon’s father because she may not able to adapt their way of living in the province. Baldo was ignoring to his older brother’s question about why did they have to go to Waig instead of Camino Real. (The reason is that their father wanted to test Maria if she is worthy to be Leon’s wife.) Baldo discussed their travel to his father. Leon’s entire family talked to Maria. 1. Who among the characters in the story you appreciate most? Why? What trait/quality/characteristics you want to this character? Why? For my opinion, I think I appreciate Maria most. Because she accepted and respected Leon for what he really is. She didn’t care what Leon’s life back in Nagrebcan. She was a supportive and a loving wife to Leon. She was so endearing and kind-hearted lady. She was very keen to meet Leon’s family. The fact that the rural is different from the city can be somewhat discouraging but the closer hey get to the house, Maria still manages to overcome any trials.
