Contribution of Capital in Growth Assignment Example | Topics and Well Written Essays - 500 words - 1

Contribution of Capital in Growth - Assignment Example   b) In such a model, the growth rate of output is ∆y/y =(SAnd), and therefore arise in depreciation cause a reduction in an economies output and since the growth rate of capital is a function of such depreciation and since they the increase in depreciation decreases capital stock. And since consumption is relative to output a decrease in output impacts in a similar way to consumption as they are positively related. Therefore it can be seen that increase in depreciation will reduce the capital stock, in the long run, reducing capital, capital-output per worker and finally consumption.   At steady state the optimum capital is utilized and since the government takes up all the units produced. The labor force utilizes all the capital available which the government takes up as indicated by point A. Also at this point, the government saves nothing since it utilizes everything in purchasing the entire output.   b) increase in government purchases will cause an increase in productivity per worker but since the capital is a function of depreciation capital at the disposal of the workers will decrease in the long run causing a reduction in the output per worker and consequently a reduction in consumption an increase in â€Å"g† cannot even match the growth of population or labor force of an economy.

Management 3000 - Essay Example In addition, the book is not only crucial for a manager and an aspiring manager but also to any individual willing to effectively learn important lessons crucial to their lives. The main theme of the book revolves around interpersonal skills on a broader perspective. However, I would divide the book into three, no actually four narrow categories, based on the achievement of the essential interpersonal skills to a manager. Of these four categories, the first one is the importance of self-awareness before seeking to understand others. Consequently, self-awareness is not something that you wake up one day and claim to have accomplished, something I have learned from the book. Apparently, self-awareness is an important and crucial skill that individuals need to conceptualize and acquire through a four-pronged approach. This covered the first unit and essentially the first four chapters in the book. I answered all the questions in these four chapters and I must say, although I read the chapters before answering the questions, there were instances that I found myself marking the wrong answer based on my personal biases. The second important thing I read pertains the need for individuals seeking to acquire interpersonal skills to learn how to work well with others in diversity. This unit covers the next four chapters of the book, that is, chapters five all the way to chapter eight. The questions are crucial to answering an individual’s perceptions about diversity. Thirdly, I read the other six chapters in the book based on the unit I would classify as understanding the team and its dynamics. This is essential for a manager who works with a team in their day-to-day operations, which effectively requires them to be knowledgeable of the dynamics controlling the team. Finally, the last unit I would call it the leadership unit. This is the actual unit that I would

Thus, the journal, The Concord Review, offers the students a chance to publish the exemplary high school history essays. Another forum founded by Fitzhugh, the National Writing Board was concerned with providing an independent assessment of high school research papers and he maintains that the students of history have made good use of it. In the following sections of the article, the author recounts the nature of students’ term papers, and the significance and consequences of writing such papers, etc. He also suggests the various ‘forces’ or hazards that dumb down writing and nonfiction reading in the high schools. According to Fitzhugh, the encouragement and publicity given to serious nonfiction academic writing are not sufficient and the endeavors such as The Concord Review are n ot able to survive due to ‘very little money and few subscribers’.

Pressure Sensor Controlled Valve Based Microcontroller In General Engineering Essay

Pressure Sensor Controlled Valve Based Microcontroller In General Engineering Essay A pressure sensor measures pressure, typically of gases or liquids. Pressure sensor can also be called as pressure transducers, pressure transmitters, pressure senders, pressure indicators and piezometers. Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure Sensor Controlled Valve based Microcontroller in General A pressure sensor controlled valve based microcontroller is a pressure sensing device that is capable of controlling a desired pressure up to the set point set by the user. Besides, the pressure sensing device also allows the user to monitor and control the entire process of the system by interfacing a Microcontroller with a PC Using RS232 and the PC Serial Port. Pressure sensor and valve are required to design pressure sensing device according to their task Nowadays pressure sensors can vary in design, performance, application suitability and cost. On the other hand, pressure sensors can be classified in term of pressure ranges they measure, temperature ranges of operation, and most importantly the type of pressure they measure. Valves are used to control conditions such as flow, pressure, temperature, and liquid level. The opening or closing of the valve is depend on the signals received from the controllers that compare a set point to a process variable where the value is obtain from the sensor that monitor the change of conditions. Besides, the opening and closing of the control valve is done by electrical, hydraulic or pneumatic system. A valve also can vary in design, pressure range and temperature range of the operation, application suitability and cost. Project Objective The main objective of this project is to design and construct a prototype of pressure sensor controlled valve based microcontroller. This prototype should have the following fundamental features: Able to control the pressure through the setpoint set by the user. Able to activate the alarm if the pressure is above a setpoint. Able to shutdown the whole process if the pressure is in critical pressure. Able to monitor the process of the control through PC. Upon successful implementation of these fundamental features, enhancements are added to improve the safety of this pressure sensor controlled valve based microcontroller. The first improvement is adding manual control function to make this control valve able to control by the user even the pressure sensor is fail to give a signal to the microcontroller. Besides, a backup battery is also added into the controller to provide power when there is absence of main power supply. The backup battery will power the circuit only in the event of failure. On the other hand, a temperature sensor will also be added into this pressure sensor controlled valve based microcontroller to maintain the optimum temperature of the gas. Project Overview The pressure sensor controlled valve based microcontroller is designed to control pressure either in gas or liquid medium in any suitable application. The pressure sensor will senses the pressure from the along the tube or pipe along the application. The bottom of the pressure sensor is connected with a T-Joint connector to the tube or pipe and the analog control signal from the pressure sensor will be connected to the analog port of microcontroller. The analog signal received by microcontroller will be analyzed by the microcontroller. The microcontroller will then control the control valve by with the signal received by the sensor. Besides, a temperature sensor (LM35) will also be added into the prototype to enhance the performance of the prototype. The temperature sensor will be mounted at the surface of the tube or pipe. The temperature sensor will sense the temperature of gas or liquids inside the tube or pipe and send a control signal to microcontroller. The analog control signal from the temperature sensor will be connected to the analog port of microcontroller. The microcontroller then will control the control valve according to the temperature received by sensor. Recently, serial port of computer slowly phase out from the market and to be replaced with USB. Nowadays, most developer will favor USB to serial converter to obtain virtual serial port. So, in order to for general and convenient use, a USB to UART converter (UC00A) which offers USB plug and play, direct interface with microcontroller will also be added to the prototype to create a monitoring system through PC. The Transmit Signal (TX) from UC00A will be connect to the microcontroller receiver pin (RX/RC7) . While the Receive Signal (RX) from UC00A will be connect to the microcontroller transmitter pin (TX/RC6) . Then, a GUI( Global User Interface) will be develop using Microsoft Visual Basic for user to monitor the process operation of the prototype. On the other hand, a backup battery of 24Vdc will also be connected parallel with the main power supply. This is to provide the prototype with a backup power supply when there is no power provided from main power supply .This is to prevent and protect the prototype from trip of circuit and critical shut down of the prototype that might cause damage to the hardware of the prototype. Besides, a LCD display (216 characters) is used to display the pressure and temperature measured from the sensors and indicates the condition or status of the control valve and the air compressor which useful for calibration, monitoring, debugging and testing. A buzzer is embedded in the prototype is used as an alarm when the pressure or temperature is above the setpoint set by the user. Project Scope and Methodology This project consisted both of the hardware and software implementation. According to the schedule, construction of the final prototype was ensured to achieve the projects objective. At the same time, software also designed to meet all the fundamental requirements. When the prototype that met the primary objectives was successfully constructed, the remaining projects duration was spent on enhancements of the prototype to make it more durable and reliable. In part one, projects objectives identification and planning had been done. After that, research on some the theoretical background of the project such as types of pressure sensor, temperature sensor, type and size of fittings and tube, types of control valve and the basic electric component for the controller that needed for this project. Electronic components were carefully selected to construct the prototype based of its functionality, reliability and cost. When hardware selection was finalized and decided, a layout for printed circuit board (PCB) was designed and fabricated. After that, a simple program was written to test, calibrate and debug the prototype to make it worked as described in the primary objective. In part two, further enhancements to the prototype were planned and implemented. The mechanical drawing of the prototype had been designed. The mechanical part of the hardware such as pressure sensor, tubing, fitting, control valve is joint up together and the wiring is connected to the into the main board(Controller) of the prototype. Besides, monitoring system of the operation is also embedded to the prototype to ease the user to monitor the operation using a PC in a control room. After all features, were completed, testing was undertaking to ensure the reliability of the whole system. Troubleshooting and debugging phase on software and hardware were necessary to make all the system become more reliable and safe. Structure of the Report This report is divided into six chapters. At the Chapter 1, Introduction to the project which includes Pressure Sensor Controlled Valve Based Microcontroller in general, Project objective, Project overview, Project scope and Methodology had been discussed.

In Chapter 5, results and discussion will be shown to explain how the pressure sensor control valves based microcontroller performs its operation. On the other hands, the problems encountered while designing the prototype either in hardware or software and how these problems solved will be also discussed in this chapter. Chapter 6 will be the summary and conclusion of the report whether all the fundamental requirements and objectives achieved for Final Year Project. Then, there will be a short recommendation or suggestion to further improve this project so that it can be used in various types of industry environment. Chapter 2: Theoretical Background 2.1 Introduction to Pressure Sensor A pressure sensor is one that will measure the pressure either gasses or liquids. Pressure is an expression of the force required to stop a fluid or gas from expanding, and it can be express as the equation below. [1] P=F/A Where: P  is the pressure, F  is the  normal force, A  is the area. Pressure Units can be expressed as the table below: Table 1: Pressure Unit 2.1.1 Types of Pressure Measurement Basically, pressures sensor can be classified in term of pressure ranges, temperature ranges and most importantly the pressure type. Pressure sensor can be classified in 5 types of pressure measurement which are : Absolute pressure sensor -Whereby the sensor measure the pressure relative to perfect vacuum pressure (0 Psi or no pressure) 2) Gauge pressure sensor -Whereby the sensor measure the pressure relative to given atmospheric pressure. For example when a tire pressure gauge read 0 Psi meaning to say there is 14.7 Psi (atmospheric pressure) in the tire. 3) Vacuum pressure sensor -The sensor is used to measure pressure less than the atmospheric pressure. 4) Differential pressure sensor -The sensor measures the difference between two or more pressures introduced as inputs to the sensing unit. 5) Sealed pressure sensor Whereby the sensor is used to measure the pressure relative to sea level pressure. 2.1.2 Types of Control Signal from Pressure sensor There are two types of Control signal from pressures sensor which are current output and voltage output signal. Current output normally ranged from 4-20ma while the voltage output normally ranged from 1-5Vdc or 1-6Vdc (The voltage output range mostly is depend by the manufacturer or the type of application). The current output and voltage output always start from 4ma and 1Vdc is to check whether the wiring of the pressure sensor is done correctly and to check whether there is faulty at the pressure sensor. For example, if the pressure sensor output a current below 4ma or 1Vdc, we have to check at the pressure sensor because they might be faulty at the pressure sensor. The current output control signal is widely used in many kind of industry compared to voltage output control signal. This is because there is no voltage drop when current output control signal travel a very long distance compare to voltage output control signal. When travelling at a very long distance, voltage output control signal will have disadvantage due to the resistance of the long wire will cause a voltage drop and might give an inaccurate result to the controller. So, the current output control signal tends to give a more accurate result compare to voltage output control signal. Due to limitation at PIC microcontroller which only has Analog-to-Digital Converter, so a voltage output control signal will be more suitable for the project. Types of Application of Pressure sensor A pressure sensor can be widely used in many types of application.For example: [2] 1) Pressure Sensing -The pressure is measure directly using pressure sensors. This is very useful in oil and gas industry, cars, aircraft, and other machinery that has a pressure functionality implemented. 2) Leak Testing -A pressure sensor can be used to sense the decay of pressure due to a system leak. This is done by either comparison to a known leak using differential pressure, or by means of utilizing the pressure sensor to measure pressure change over time. 3) Level Sensing A pressure sensor can also be used to calculate the level of a fluid. This technique is commonly employed to measure the level of contents in a tank (such as in a water tower). For most practical purposes, fluid level is directly proportional to pressure. In the case of fresh water where the contents are under atmospheric pressure, 1psi = 27.7 inH20 / 1Pa = 9.81 mmH20. The basic equation for such a measurement is P  =  p  *  g  *  h Where P = Pressure, p = Density of the Fluid, g = Standard Gravity, h = Height of fluid column above pressure sensor Introduction to Valve A valve is device that is used to regulate the flow of a fluid or gasses by opening and closing or partially obstructing various passageways. A valve can be operating either in manual operation or automatic operation driven by change in pressure, temperature or flow. For manual operation, the opening and closing of the valve is control by using hand wheel, lever or pedal using human force. Meanwhile for the automatic operation, the opening and closing of the valve is control using an actuator .An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements. Nowadays, Actuators are widely used for the purposes of automatic control such as in washing machine cycles, remote control such as the use of a centralised  control room, or because manual control is too difficult such as when the valve is very large. [3] 2.2.1 Types of Actuator in the Valve Valve can be classified on how they are actuated. Among them are: [3] Hydraulic Pneumatic Manual Solenoid Motor For a hydraulic system actuator valve is normally used to control a high pressure while Pneumatic system actuator valve is normally used to control a medium pressure in application. Meanwhile low pressure, solenoid or motorized system actuator valve can be used. 2.2.2 Application of Valve Valve can vary widely in form and application. The size of the valve is typically range from 0.1mm to 60cm. Some special valve can have a diameter exceeding 5 metres. The cost for a valve is depending on types of the design, material build, range of temperature and pressure and manufacturer. When a designer, engineer, or user decides to use a valve for an application, he/she should ensure the rated maximum temperature and pressure are never exceeded and that the wetted materials are compatible with the fluid the valve interior is exposed to. [3] The industries in which the majority of valves are used are oil and gas, power generation, water reticulation, sewerage and chemical manufacturing. [3] 2.3 Introduction to Tubing Tubing is pipe or a hollow cylinder for the transmission of fluid (liquid or gas). The term of pipe and tubing can be interchangeable although there are minor distinctions exist- basically, tubing imply tighter engineering requirements than pipe. Both pipe and tubing can be varies in different rigidity and permanence. For examples, a hose is normally portable and flexible. Besides, tubing and pipe can be specified by standard pipe size designation. Types of tubing are specified by the actual inside diameter, outside diameter and the wall thickness. [4] 2.3.1 Types of Tubing Basically, there are few types of tubing can be used in industry. Among them are: Copper Tubing Stainless Steel or Aluminium Tubing Plastic Tubing For copper tubing, there are two basic types of copper tubing, soft copper and rigid copper. Copper tubing can be joined using flare connection, compression connection, or sweat (solder). Soft copper tubing can be bent easily to travel around obstacles in the path of the tubing while a rigid copper cannot be bent and must use  elbow fittings  to go around corners or around obstacles. Soft copper is the most popular choice for refrigerant lines in  split-system  air conditioners and heat pumps while rigid copper is most popular choice for water line. [5] For Aluminium Tubing, it is sometimes used in industry because it is resistance to corrosion and solvents, and for its ductility. Besides, aluminium cannot create sparks when there is a transmission of flammable solvent and the weight for aluminium is lighter compare to steel and iron which make it suitable to use in many types of industry. [5] Aluminium tubing can be joined using flare connection, compression connection, or sweat (solder). Aluminium tubing can be used for heat transfer tubing such as in refrigerant systems. [6] For Plastic Tubing, there are few types of plastic tubing which are PVC(polyvinyl chloride) and CPVC, Polyethylene, Rigid Polypropylene, ABS (acrylonitrile butadiene styrene) and Nylon tubing. The most popular for plastic tubing is PVC. It is rigid, and uses thread or glue connections. Besides, it is available in several of pressure range. [5] Plastic tubing is widely used for its light weight, chemical resistance, non-corrosive properties, and ease of making connections. [6] 2.3.2 Types of Tube Fittings There are many types of connection methods for tubing application in industry. The four most common types of tube fttings connections are: Compression Tube Fittings Flare Fittings Bite-Type Tube Fittings Mechanical Grip-Type Tube Fittings The Compression Tube Fitting was the first tube fitting to be introduced, which consist of three components: nut, body and gasket ring or ferrule. The disadvantages of compression tube fittings was it can withstand only minimal pressure and the remake is very difficult due to the contrustion of the sealing ring. [7] CompressionTube Fitting The Flare Fitting was the another variation in tube fittings designs. The fittings is made up from a nut, sleeve and body with a flare or coned end. During installation of a tubing, a special flaring tools are usually required .The disadvantages of flare fittings is that flaring of the tubing may cause stress riser at the base of the flare or cause the axial cracks on thin tubing. [7] Flare Fitting For Bite-Type Tube Fitting , it is used to accommodate higher pressure application over the compression tube fitting design. The fittings is typically made up with a nut, body and ferrule(s) having a sharp leading edge, which give bites into the skin of the tubing to achieve griping and holding ability. There are two types of design for bite-type tube fittings which are the single ferrule and twin ferrule design. In single ferrule bite, the nose of the ferrule performs two functions. The first function is to bite into the tube to hold it and second function is to provide a sealing element for the coupling body.In twin ferrule bite, the back ferrule is used to bite and provide gripping into tube and the front ferrule is used for sealing element for the coupling body. [7] Single-Ferrule Bite-Type Two-Ferrule Bite Type Meanwhile for Mechanical Grip-Type Tube Fittings are typically two-ferrule in design. The front ferrule is used to seals by coining the surface of the tubing and coupling body. While the back ferrule is used holding action. The back ferrule grip the tube for a distance just out-board from tube holding point of the ferrule nose to enhance vibration resistance. The main advantanges of this design compare to the bite-type fittings is that break and remake of the fitting after installation can be more successfully accomplished without damage to either the fitting components or the tubing. [7] Mechanical- Grip Type 2.4 Introduction to Pipe Thread Basically ,there are two types of standard for pipe thread which are : British Standard Pipe- BSP American National Pipe-NPT/NPS Both of British Standard pipe and American National Pipe is designated by trade size rather than actual diameter. Under BSP, there are two basic types of BSP threads which are the BSPT (British Standard Pipe Taper) which is also know as R threads and BSPP (British Standard Pipe Parallel) which is also known as G threads. Both of the BSPT and BSPP have the same thread angle, shapre and pitch ( threads per inch). The only difference for BSPT and BSPP is BSPT threads are tapered and BSPP threads are straight ( parallel). BSP thread have a 55o include angle and have rounded peaks and valleys. On the other hands, for NPT, there are also two basic types of national pipe threads which are NPT ( National Pipe Taper) abd NPS ( National Pipe Straight) . Both NPT and NPS have the same thread angle, shape, and pitch (threads per inch).   However, NPT threads are tapered and NPS threads are straight (parallel).   Both threads have a 60 ° included angle and have flat peaks and valley 2.4.1 NPT vs BSP Pipe NPT thread are widely used in United State but, BSP thread are more widely used in many other countries.The actual specified outside diameters of American National Pipe is slightly different from British Standard Pipe,.NPT/NPS and BSP thread are not compatible with each another. This is due to the differences in their thread forms and pitch . NPT/NPS threads have a 60 ° included angle and have flattened peaks and valleys while a BSP threads have a 55 ° included angle and have rounded peaks and valleys As conclusion, never ever try to mate a BSP fittings with an NPT or NPS fittings if the pressure holding capability is at all critical. CHAPTER 3 HARDWARE AND SETUP DESIGN In this chapter, the hardware components used to setup the hardware would be elaborated and discussed. Each components features and its operation were studied before proceed to the hardware design. These components were tested on breadboard individually with simple program. The main purpose of this is wanted to determine components and algorithms used are work and function properly. Based on these algorithms, a complete program could be designed to make all the components work in the correct manners. The details about software methodology will be explained at next chapter. After all the hardware components passed the testing, a proper design of Printed Circuit Layout (PCB) was needed. A good and neat design of the PCB would ensure all the components work stability and properly to achieve the project primary objectives. During this stage, Electromagnetic Interference (EMI) theory had studied to prevent undesired manners such as noise or crosstalk occurred in the PCB board. Besides , the design drawing of hardware prototype is also had been studied before assembling the hardware prototype. At the last stage, the tubing, fittings, valve, pressures sensor and pressure gauge is assemble carefully in order to prevent gasses leakage from prototype. 3.1 Microcontroller Unit (MCU) A microcontroller is a computer system that runs on a single integrated circuit. It usually consists of Central Processing Unit (CPU), memory unit and Input/Output (I/O) modules. Apart from these, a MCU also contains timers, counters and interrupt scheduling circuitry. Microcontrollers are widely applied in the robotics and embedded system controllers. Different microcontroller models may offer extra peripherals and registers for some applications (eg. UART, SPI, I2C and etc.). They usually run in a fixed oscillating frequency. There are advanced microcontrollers which are 32-bits microcontroller developed nowadays. But, 8-bit microcontrollers are usually sufficient to design a small embedded controller. In this project, Microchip microcontroller had been chosen due to its extra features. For instance, PIC had built-in ADC module to ease the analog to digital signal converting and Universal Synchronous Asynchronous Receiver Transmitter (USART) module to communicate with PC. 3.2 Microchip PIC Microcontroller PIC stand for Peripheral Interface Controller. Until now, Microchip had developed and manufactured multiple families of PIC microcontroller in different packages. They are several families in a certain category such as PIC10, PIC12, PIC16, and PIC18 in 8-bit PIC microcontrollers, PIC24F, PIC24H, dsPIC30 and dsPIC33 in 16-bit PIC microcontrollers and PIC32 in 32-bit PIC microcontroller. The PIC microcontroller that is used in this project is PIC16F877A. One of the reason this PIC microcontroller was choosen because it is in 40-pin DIP package. It was also chosen because it is powerful and yet easy to program CMOS FLASH with only 25 single word instructions based 8-bit microcontroller. With the 20MHz operating frequency, the PIC only need only 200 nanoseconds to execute and instruction.

Comparing Social Commentary in Dover Beach, Second Coming, and Church Going :: compare and contrast essay examples

Comparing Social Commentary in Dover Beach, Second Coming, and Church Going Human society has always struggled with the conflict of faith versus technology. Faith has always been a symbol of order, and increasing technology has always been the scapegoat for "mere anarchy." When faith ebbs, technology or new scientific concepts are blamed. Technology is a convenient target because when people lose faith in the church, science is a hard-based, factual thing in which to believe. The increasing chaos in society can be blamed on the decreasing faith in religion that has been shifted to technology. After the fall of the Roman Empire, European society was in chaos. Since no other civilizing force in which to believe was in existence, when the Roman Catholic Church made itself a organizing power, it set up a precedent that attached itself to the mind set for the next few centuries. Religious beliefs are synonymous with the "calm" and the peace that relieve life's turmoil. For a long period of time, there was no other steadying force, so "the Sea of Faith" was the sole source for easing "the turbid ebb and flow of human misery." Tradition has kept this view of religion popular. Still, religion itself cannot hold the attention of human society forever. Eventually, as displayed in "Dover Beach," faith in religion and its structure will fade in the light of new ideas and new human inventions. Society's faith cannot always be "full" because as civilizations grow individuals become more independent. They begin to think for themselves, which causes life to become more subjective. With less imposed structure, individuals will determine that they do not subscribe to all of what their predecessors believed, and they are left "wondering what to look for." Technology often replaces religion because it is far more tangible than the concepts of organized religion that require blind faith. It is easier to believe in something touchable. In "Church Going," this attitude is examined. A wistfulness for a time when faith came easier is apparent, but there is also "an awkward reverence" for the ways of religion even if they are no longer believed. Once people place their faith in technology rather that something spiritual, they will find that while technology is concrete, it does not provide guidance for social behavior or the human spirit as most religions do. In "The Second Coming" the world is spinning out of control.

Pychology in Daily life Experiences Essay

Introduction Many people might doubt that how can psychology relate to our life? There come up with the answer to support everybody’s confusion. The psychological research has indicated that the cause of every experience: your physical and mental health, ability to form close relationships endurance, capacity for learning and personal growth.(Richard J.Gerrig & Philip G Zimbardo , 2008)All of these are related to our daily life. Though the psychological theories, we are able to learn ourselves by scientific explanation. Stress -Changes Hans Selye defines stress ass the nonspecific response of the body to any demand on it.;the arousal ,both physical and mental ,to situation or event that we perceive as threatening or challenging. In our daily life, stress might come from the on-set situation or off-set situation.( Hans Selye,2011) For example, even lecturer mentioned the date of exam, when the day is near ,I will feel very stress also. On the other hand, if lecturer sudden announces that we are going to have pop-quiz immediately. With no doubt ,it will be the causes of my stress. As you can see, the root of stress is changes in life. Even the changes are kind of positive things. When I knew I was accepted by UCSI University, at the moment I was very happy. Latter on, all the possible situation come up in my mind. Am I able to adapt the new environment? Am I able to pass all the subjects? We all wish to have smooth life, but these positive or negative changes are the challenges to our life. Sensory adaptation Sensory adaptation is repeated or constant stimulation decreases the number of sensory messages sent to the brain ,which causes decreased sensation.(Living psychology )For example, the things happened at the moment after the PE class,all the students with sweating body go into the class room with air conditioning room.The body odor will full fill with the room gradually. People in the room might not aware of the smell, but when I came in the class room , I complained the uncomfortable smell. After I stayed in the class for a while, my sensory was tired of the odor. Then I won’ complain the smell anymore. Controlled process The controlled process is the mental activities requiring focused attention that generally interferes with other ongoing activities ( Huffan. K,1999.). Whenever I have performed on the stage, I have to concentrate on myself. Pay attention on what is the next step,what is the next posture .There is no time and strictly not allowed to think of other things such as how does audience response and how do judges score. Only until the end of performance I can think f these things. Automatic process Automatic process is activities requiring minimal attention and having little impact on other activites.( Huffan,K ,1999).I have an experience that working at restaurant cashier. The restaurant I worked has a cash machine .The first month of work was terrible. I was so scary to touch the button.It made me frustrated all the time. The amount of money numbers full of my mind .I dare not to count wrongly to company’s property.Whenever I stand in front of cash machine I always sweating. All these thing I got though it after I worked there for eight months. Later on,I was not only can control the cash machine easily but also can talk to the customer in the same time. Gate-control theory The theory that the spinal cord contains a neurological â€Å"gate† the blocks pain signals from the brain when flooded by competing signals.(Saul Kassin,1995) Ex. Wearing high heels actually killing me so much, but the pain didn’t bother us during I wear them out to show off my beautiful high heels. Another experience is monthly period. Whenever our â€Å"Best friend â€Å"coming, it is a difficult time for girls. Most of the girls will not to focus on the pain instead of keep thinking the pain. Conclusion To sum up, finding myself by psychology theories is somehow interesting. Just discover the reasons that why is my behavior acting so. Describing by science method is more convictive. After learning the basic psychology, now I start to observe people surrounding in my life. Try to explain their behavior and discuss with my friends. I found myself can tolerant people more than before. I can understand the people whose behavior are not accepted by me .Actually everyone has their different childhood background or genetic reasons. Learning psychology is not only learn the knowledge but also improve our self-development. Reference Richard J.Gerrig & Philip G Zimbardo .(2008).Psychology and life.(8th ed).

Book Keeping Essay

Book keeping it also referred as the keeping of book. Book keeping is the process of keeping full, accurate, up-to-date business records. Proper methods can help businesses effectively manage cash flow, stay abreast of profit and losses, and develop plans for the future based on financial trends. Furthermore, keeping accurate book is required by both federal and local tax agencies. The book keeping process involves making a record of the monies received by a business as well as the monies paid out. It encompasses money a company owes to vendors, employees, tax agencies, contractors, and any other individual or entity. Likewise, accurate records of amounts owed to a company by outside individuals and organizations are also recorded in a company’s books. Though necessary and beneficial to business owners, the task can be very time consuming. With no exceptions, every monetary amount that is paid or received must be recorded. Additionally, accuracy is of the utmost importance, making keeping the books in a rushed manner a very bad idea. As business owners are often lacking in time, many choose to hire professional bookkeepers to keep company records well maintained. Of the many reasons for keeping accurate records, business and income taxes are among the most important. In the United States, for example, the Internal Revenue Service requires business owners to keep financial records that are complete and up-to-date. State and city tax agencies may require businesses to maintain accurate records as well. In fact, a business owner who fails to keep acceptable financial records may be liable for significant monetary fines or other penalties. A company’s books are used to determine the amount of taxes the company must pay, and they are also used in preparing tax returns. Sometimes, a tax agency may decide to investigate the information reported on a return or other type of tax-related document. In such cases, business owners are required to present accurate records for the tax agency’s inspection. Failure to do so could lead to hefty fines, penalties, or in severe cases, imprisonment. Although hiring bookkeeping professionals may be a good idea for many companies, not all business owners can afford to do so. This is particularity true of smaller, home-based, or start-up businesses. Fortunately, there are many computer programs designed to make the task of keeping the books manageable and less time consuming. Many programs handle all of the calculations for the user, taking the worry out of keeping accurate figures. Available even to those on tight budgets, this software makes record keeping easy. (N. Madison, 2013, Wise Geek.)[online] ACCOUNTING CYCLE The accounting cycle is often described as a process that includes the following steps: identifying, collecting and analyzing documents and transactions, recording the transactions in journals, posting the journalized amounts to accounts in the general and subsidiary ledgers, preparing an unadjusted trial balance, perhaps preparing a worksheet, determining and recording adjusting entries, preparing an adjusted trial balance, preparing the financial statements, recording and posting closing entries, preparing a post-closing trial balance, and perhaps recording reversing entries. Cycle and steps seem to be a carryover from the days of manual bookkeeping and accounting when transactions were first written into journals. In a separate step the amounts in the journal were posted to accounts. At the end of each month, the remaining steps had to take place in order to get the monthly, manually-prepared financial statements. Today, most companies use accounting software that processes many of these steps simultaneously. The speed and accuracy of the software reduces the accountant’s need for a worksheet containing the unadjusted trial balance, adjusting entries, and the adjusted trial balance. The accountant can enter the adjusting entries into the software and can obtain the complete financial statements by simply selecting the reports from a menu. After reviewing the financial statements, the accountant can make additional adjustments and almost immediately obtain the revised reports. The software will also prepare, record, and post the closing entries. (Harold,A.2013,Accounting Coach.)[online]. SOURCE DOCUMENTS Source documents are documents, such as cash slips, invoices, etc. that form the source of (and serve as proof for) a transaction. In other words, they are the first documents that exist relating to a transaction. Invoices, cash slips, receipts, check counterfoils, bank deposit slips ,credit notes ,debit notes ,voucher , purchase orders and even internet payment confirmations are all source documents. For example: Invoices Credit Notes Receipts Voucher Purchase orders BOOK OF PRIME ENTRY Book of prime entry is book used in recording transaction. Books of prime entry are also known as books of original entry or subsidiary books. Types of books of prime entry: Books of prime entry are also known as either ‘journals’ or ‘daybooks’. The term ‘day book’ is, perhaps, more commonly used, as it more clearly indicates the nature of these books of prime entry – entries are made to them every day. The commonly used books of prime entry are: Sale Day Book /Sale Journals –Sale journals is to record credit sales. Purchases Day Book/Purchases Journals –Purchases journals is to record credit purchases. Sales Return Day Book/Return In Journals –Return in journals is to record returns from customers. Purchases Return Day Book/Return Out Journals –Return out journals is to record returns to suppliers. General journal/The journal –The journal is to record other transactions. The cashbook is a combined account of the cash account and the bank account. It is the only one of the six daybooks that is both an account and a daybook at the same time. Apart from the cashbook, all the other double-entry accounts are kept in one of the three ledgers. Example for 3 Column Cash Book LEDGER (T-ACCOUNT) The ledger is a collective term for the accounts of a business. (A ledger of accounts is like a school of fish). The accounts are in the shape of a ‘T’ and thus are often referred to as ‘T-accounts’. In this step we take all the debits and credits (journals) relating to one account – let’s say ‘bank’ – and draw up an account for bank that shows all the transactions relating to it. The different types of ledgers most businesses use are: Sale Ledgers –Sale ledgers is to record customers account balance. Purchases Ledgers –Purchases ledgers is to record suppliers account balance. General Ledgers –General ledgers is to record miscellaneous account. Example: PETTY CASH BOOK The petty cash book is used to record the changes to the petty cash fund – both money put into the fund and money taken out. The fund is commenced with a petty cash advance cheque and topped up with a reimbursement cheque at the end of each petty cash period.The petty cash book is prepared from the petty cash vouchers, as well as the details from the advance and reimbursement cheque butts. The petty cash book is prepared from: –advance (and/or reimbursement) cheque butt/s –completed and authorised petty cash vouchers. The totals can be checked by cross-adding related column totals.The total of the vouchers (Cash Payments column total) added to the balance left in the petty cash fund (Balance column) should always equal the imprest amount. TRIAL BALANCE A sheet displaying all the accounts of a business, drawn up as a trial (test) of whether the total of all the debit balances equal the total of all the credit balances (A balance is the amount of an item at a point in time. For example, The balance in the bank account on the 1st of January was $5,000.). The trial balance is prepared as a final check just before the financial statements are drawn up. The trial balance is our penultimate step in the accounting cycle. Example for Trial Balance: FINAL ACCOUNT Final accounts are all of the financial statement for a business or company at the end of the fiscal or calendar year, on whichever the business calendar the company operates. The statements for the final accounts show the gross profit and net income of the company. A number of accounts are included, such as the profit and loss statement for the business, the balance sheet, and the trading account. The profit and loss statement tracks all of the income that comes into the company, as well as the expenses that the company pays out. The profit and loss statement covers a specific period — typically the fiscal year, but it can also cover the calendar year. It shows how revenue becomes net income, and whether or not the company made money for the year. While the company tracks these figures throughout the year, the final accounts include the statement for the cumulative fiscal or calendar year. The balance sheet is another one of the business financial statements that are prepared as part of the final accounts process when the year closes out. The balance sheet provides a quick look at how the company is doing at that specific moment in time, at the end of the year. In addition to assets and liabilities, a balance sheet also includes information on shareholder equity. Trading accounts cover profits and losses incurred from trading securities. Many companies invest in stocks, bonds, mutual funds and other types of investment funds. The final accounts for the trading account show the amount of gain or loss from these investments at the end of the year that the company runs on. Final accounts and the statements that make up these accounts typically help companies to prepare their various tax returns. If the company accountant prepares the tax statements, then the accountant prepares these statements for his or her own use. If the company hires an outside accountant or accounting firm, then the statements for the final accounts are handed over to the third party, so they have the information they need to prepare the company’s tax returns and any of tax paperwork that is required. (Kristie,L and Wilborn,C.2013,Wise Geek)[online] INCOME STATEMENT A financial statement that measures a company’s financial performance over a specific accounting period. Financial performance is assessed by giving a summary of how the business incurs its revenues and expenses through both operating and non-operating activities. It also shows the net profit or loss incurred over a specific accounting period, typically over a fiscal quarter or year. Also known as the â€Å"profit and loss statement† or â€Å"statement of revenue and expense.† Example for Income Statements: STATEMENT OF FINANCIAL POSITION A statement of financial position, also known as a balance sheet, is a financial document that provides an overview of an entity’s finances at a given point in time. These statements are commonly used by companies large and small, but they can also be applied to personal finances, for people who want to generate a document that they can use to review their financial situation for the purpose of making budgeting decisions or financial plans. Many accounting software programs have mechanisms to automatically create one. There are two main areas on a statement of financial position. One covers the assets, everything owned by the person or company, including real estate, cash in hand, contents of bank accounts, and so forth. The other side includes the liabilities, funds owed. A statement usually breaks these sections up into several categories for ease of reference, so that people can quickly look up a topic of particular interest, such as accounts payable or overdue loans. The liabilities also include the ownership equity or the shareholder equity in the business. The assets should equal the liabilities once the ownership or shareholder equity has been factored in, and if they do not, it is a sign that the financial statement is out of balance. This is in accordance with the accounting equation, which states that assets = liabilities + ownership or shareholder equity. Incidentally, this explains the term â€Å"balance sheet,† which reflects the idea that the two sections of the sheet should be equal or balanced. Commonly, a statement of financial position will be generated at the end of every month. Looking up past months can provide information about how a company’s finances are progressing, and these documents can also be compared with statements from the same month in prior years. Using this document, decisions can be made about the next steps to take. If, for example, a company has a lot of assets, it may be a sign that it can comfortably expand because it has the available capital to do so. Companies that are publicly traded must provide public disclosures about their financial health, including statements of financial position. These are provided to shareholders by request and are also commonly published to make them readily accessible to prospective investors. If a company has a website, they might be found on a section of the website that includes documents that the company is required to disclose by law. (Smitch,S. and Wallace,O.2013,Wise Geek)[online] Example for Statement of Financial Position: CONCLUSION Book keeping is important to proper accounting records because proper methods can help businesses effectively manage cash flow, stay abreast of profit and losses, and develop plans for the future based on financial trends. Furthermore to complete the financial account, accounting cycle are used. The accounting cycle included source of document, books of prime entry, ledgers, trial balance and the final accounts.
