Advantages and disadvantages of public and private companies

Advantages and disadvantages of public and private companies Public companies have the advantage over private companies in access to capital to grow the business. But private companies can react more quickly to challenges and opportunities without going through exhaustive decision making processes. Advantages and disadvantages of public companies. Public company is able to raise funds and capital through the sale of its securities it is important historically. To ease of raising capital public companies may issue their securities as compensation for those that provide services to the companies, such as their directors, officers and employees. The basic advantage of public facilities is that the tax paid by the people is used in developing facilities for the people who paid the taxes. Public companies are typically established fair market value in the stock exchange where it is determined by price of security and sold where security is traded. The cost of being public is huge and the benefits are questionable if you are a microcap. A public company has to meet the requirement to publicly disclose much financial information which could be useful to competitors. Public companies spend more for certified public accountants and other bureaucratic paper work required of public companies by government regulation. Public companies need a huge capital to get the capital market for purchasing equipment and plant expansions. Because of security regulations public companies requires doing more of paperwork. Public companies have an additional cost for administrative overhead and personnel needed to meet regulatory requirement. It could be quite expensive for stockholders for mailings. Advantages and disadvantages of private companies Private companies are less expensive as it requires very less paper work and very limited shareholders. As it is the private companies information are secured, so thats the way they are dealing more with government agency, because private companies works sensitive with government. The business is kept confidential as it is a private company which is less interacting with media or press. Shareholders have very less liability, as they have agreed upon business stability but the business is not disturbed by the death of shareholders. While private companies may also issue their securities as compensation for services, the recipient of those securities often have difficulty selling them on the open market. Private companies have high taxes, less dividends and the often deter small-medium sized business owners. Ans) 2 The small private companies are directed on the attentions to contral according to the commander theory it is excercised by the people. The power to deploy the resources are pointed by the persons or a group of persons. The person who has such power can command over this resources. By using commander notion we cannot appear into the reasonable interpretation of principle and functions of accounting without using false abstraction, such as the entity or fund. A sole proprietor is a commander. So the proprietor have control over the resources of their firm as they are emphasies by the ownership aspect. Control is an economic function whereas ownership have to work in the legal relationship. Profit is generated from the resources have ability to command over this resources by the proprietors. According to commander theory the supporters are undue and placed on the proprietor as owner rather than as manager. But in large companies shareholder have very less command over its resources as they are part of owners, managers have very limited control over resources. The focus of accounting for such companies affects the functions of accounting which is carried out for commanders. For the benefit of the people accounting records are maintain, financial statement are prepared and are analysed by people on and behalf of people. And financial statement reports by commander to commander. The commander of the firm undertakes accounting procedures, accept owner or entity or fund. In the balancesheet the report of which is showing the resources which is entrusted to the commander and control but does not own. Balancesheet is prepared on behalf of commander is a statement which shows the sources from hwere the commander has rececived resources and the application of those resources. In the accounting practice commander theory is not directly effected. Proprietary and entity theories appears on the oppostie view which is the notion of economic control, and the use of procedures related to propietrary and entity view are simaltaneouly emphasised by the commander theory. In determining the nature of asset and in determining what entities become paramount by the notion of control which is included in consolidation account. The objective of financial objective is dependent for small enterprise which value upon to pursued decision making, practical and control. The bring the value in control and not easily measurable, and small business frequently taking action such as if the company needs more new capital for business but they will refuse to bring new stockholders. To access the financial infornmation from the external financing inevitably brings with it and arranged its over coming difficulties between those enterprise and the financiers concerned. The information of a report that of a small enterprise must required to support the debt financing. Financing and profit distribution decisions made in small enterprise might be strongly influnced by a desire to avoid such accountibility. Ans) Proprietary theory emphasies for the small business whereas entity theory for large business. Proprietary theory views the firm as an renewal of its owners but by keeping in mind as an accounting purpose the entity does not exist seperately from its owners. For this outlook it is supported by the various participant in the business sectors. In large companies shareholders who has very limited holdings but they are not seen as owner of the company but looks as an investors. So they believe that they are working for company and as an shareholders. For the benefit of the company they reinvest their dividends as belonging to the company. As from the owners perspective financial statement are prepared for the advantage of the owners. And for controlling shareholders assets of the company is seen as asset of company whereas liablities of company are viewed as a liabilities. As an wealth of the company increases with increases in revenue and decreases with more expenses. The proprietary theory affects the only in each sole company for increasing profit instead of entire companies. As per the entity theory they maintain financial statement under the joint financial statement as per the view of the business entity. For the accounting purpose legal entity are separately considered from owner. In the interest of the entity consolidated statement are intended to all parties of the entity. The person who are having ownership interest in the consolidated entity are considered separately and distinct as an controlling and non-controlling shareholders of the entity. No preference, no emphasis is given to any members of these entity group such as controlling shareholders non-controlling shareholders and consolidated entity. All profit or loss assets or liabilities equity are merged into one group of entity under the entity theory and they are united for one entity as not for separate controlling and non- controlling shareholders who are involved in the joint net income and the ownership of business group. If a company decides to transform itself into a public company from a private company their is no magic or formula which qualifies a private company to transform into a public company but the factors which determine a public company can hire plenty of shareholders from any market which can sells its product or services. And company should keep in mind a good regional and national market is in a boom situation you can transform into the public company. The best way to know that it is beneficial or not for company whether it should transform to public company is their management team can grow your company or not and their profit margin because it affects on the accounts of the company. Ans4) Yes, I do agree with this statement. Proprietary view of accounting keeps in mind as an interest of all accounting concepts, procedures and rules are formulated to the owners. Owners of the company seeks to acheive their purpose and to maximise their profit or wealth. As per the proprietary view for the small business really control by their owners and generally are not necessary to prepare general-purpose financial statement for a business. General purpose financial statment is only prepared when it is needed by its users for its financial statement which is opposed to get those requirement of only a exacting group such as an management, creditors, investors or regulatory bodies. And this whole prupose of financial statement is based on GAAP (Generally accepted accounting principle). Small business does not require to prepare general purpose financial statement and they do not really make an extension of their owners because their profit will be maximise and will not be managed properly. On presenting accounting standards for small business entities they have their levels for satisfaction or dissatisfaction which are hurdles and burden on imposing the financial statement to the prepares and their standards become weaker. Small business entities cannot bear to maintain financial statement as it is costly and burdensome which casues the overall cost to continue to increase. http://www.smartcompany.com.au/Free-Articles/The-Briefing/20081127-Private-companies-more-likely-to-fail.html

Wireless Charging Of Mobile Phones

Wireless Charging Of Mobile Phones Abstract -With mobile phones becoming a basic part of life, the recharging of mobile phone batteries has always been a problem. The mobile phones vary in their talk time and battery standby according to their manufacturer and batteries. All these phones irrespective of their manufacturer and batteries have to be put to recharge after the battery has drained out. The main objective of their manufacturer and battery make. In this paper a new proposal has been made so as to make the recharging of the mobile phones is done automatically as you talk in your mobile phone! This is done by use of microwaves. The microwave signal is transmitted from the transmitter along with the message signal using special kind of antennas called slotted wave guide antenna at a frequency of 2.45GHz. There are minimal additions, which have to be made in the mobile handsets, which are the addition of a sensor, a rectenna and a filter. With the above setup, the need for separate chargers for mobile phones is e liminated and makes charging universal. Thus the more you talk, the more is your mobile phone charged! With this proposal the manufacturers would be able to remove the talk time and battery standby from their phone specifications! INTRODUCTION THE ELECTROMAGNETIC SPECTRUM To start with, to know what a spectrum is: when white light is shone through a prism it is separated out into all the colours of the rainbow; this is the visible spectrum. So white light is a mixture of all colours. Black is NOT a colour; it is what you get when all the light is taken away. Some physicists pretend that light consists of tiny particles which they call photons. They travel at the speed of light (what a surprise). The speed of light is about 300,000,000 meters per second. When they hit something they might bounce off, go right through or get absorbed. What happens depends a bit on how much energy they have. If they bounce off something and then go into your eye you will see the thing they have bounced off. Some things like glass and Perspex will let them go through; these materials are transparent. Black objects absorb the photons so you should not be able to see black things: you will have to think about this one. These poor old physicists get a little bit confused when they try to explain why some photons go through a leaf, some are reflected, and some are absorbed. They say that it is because they have different amounts of energy. Other physicists pretend that light is made of waves. These physicists measure the length of the waves and this helps them to explain what happens when light hits leaves. The light with the longest wavelength (red) is absorbed by the green stuff (chlorophyll) in the leaves. So is the light with the shortest wavelength (blue). In between these two colours there is green light, this is allowed to pass right through or is reflected. (Indigo and violet have shorter wavelengths than blue light.) Well it is easy to explain some of the properties of light by pretending that it is made of tiny particles called photons and it is easy to explain other properties of light by pretending that it is some kind of wave. The visible spectrum is just one small part of the electromagnetic spectrum. These electromagnetic waves are made up of two parts. The first part is an electric field. The second part is a magnetic field. So that is why they are called electromagnetic waves. The two fields are at right angles to each other. THE MICROWAVE REGION Microwave wavelengths range from approximately one millimeter (the thickness of a pencil lead) to thirty centimeter (about twelve inches). In a microwave oven, the radio waves generated are tuned to frequencies that can be absorbed by the food. The food absorbs the energy and gets warmer. The dish holding the food doesnt absorb a significant amount of energy and stays much cooler. Microwaves are emitted from the Earth, from objects such as cars and planes, and from another because microwave energy can penetrate haze, the atmosphere. These microwaves can be detected to give information, such as the temperature of the object that emitted the microwaves. Microwaves have wavelengths that can be measured in centimeter! The longer microwaves, those closer to a foot in length, are the waves which heat our food in a microwave oven. Microwaves are good for transmitting information from one place to light rain and snow, clouds, and smoke. Shorter microwaves are used in remote sensing. These mi crowaves are used for radar like the Doppler radar used in weather forecasts. Microwaves, used for radar, are just a few inches long. Because microwaves can penetrate haze, light rain and snow, clouds and smoke, these waves are good for viewing the Earth from space Microwave waves are used in the communication industry and in the kitchen as a way to cook foods. Microwave radiation is still associated with energy levels that are usually considered harmless except for people with pace makers. Here we are going to use the S band of the Microwave Spectrum. Microwave frequency bands Designation Frequency range K Band 18 to 26 GHz Ka Band 26 to 40 GHz Q Band 30 to 50 GHz U Band 40 to 60 GHz V Band 46 to 56 GHz W Band 56 to 100 GHz L Band 1 to 2 GHz S Band 2 to 4 GHz C Band 4 to 8 GHz X Band 8 to 12 GHz Ku Band 12 to 18 GHz The frequency selection is another important aspect in transmission. Here we have selected the license free 2.45 GHz ISM band for our purpose. The Industrial, Scientific and Medical (ISM) radio bands were originally reserved internationally for non-commercial use of RF electromagnetic fields for industrial, scientific and medical purposes. The ISM bands are defined by the ITU-T in S5.138 and S5.150 of the Radio Regulations. Individual countries use of the bands designated in these sections may differ due to variations in national radio regulations. In recent years they have also been used for license-free error-tolerant communications applications such as wireless LANs and Bluetooth: 900 MHz band (33.3 cm) ( also GSM communication in India )2.45 GHz band (12.2 cm) IEEE 802.11b wireless Ethernet also operates on the 2.45 GHz band. TRANSMITTER DESIGN The MAGNETRON (A), is a self-contained microwave oscillator that operates differently from the linear-beam tubes, such as the TWT and the klystron. View fig(1) is a simplified drawing of the magnetron. CROSSED-ELECTRON and MAGNETIC fields are used in the magnetron to produce the high-power output required in radar and communications equipment. The magnetron is classed as a diode because it has no grid. A magnetic field located in the space between the plate (anode) and the cathode serves as a grid. The plate of a magnetron does not have the same physical appearance as the plate of an ordinary electron tube. Since conventional inductive-capacitive (LC) networks become impractical at microwave frequencies, the plate is fabricated into a cylindrical copper block containing resonant cavities that serve as tuned circuits. The magnetron base differs considerably from the conventional tube base. The magnetron base is short in length and has large diameter leads that are carefully sealed into the tube and shielded. The cathode and filament are at the centre of the tube and are supported by the filament leads. The filament leads are large and rigid enough to keep the cathode and filament structure fixed in position. The output lead is usually a probe or loop extending into one of the tuned cavities and coupled into a waveguide or c oaxial line. The plate structure, shown in fig(1), is a solid block of copper. The cylindrical holes around its circumference are resonant cavities. A narrow slot runs from each cavity into the central portion of the tube dividing the inner structure into as many segments as there are cavities. Alternate segments are strapped together to put the cavities in parallel with regard to the output. The cavities control the output frequency. The straps are circular, metal bands that are placed across the top of the block at the entrance slots to the cavities. Since the cathode must operate at high power, it must be fairly large and must also be able to withstand high operating temperatures. It must also have good emission characteristics, particularly under return bombardment by the electrons. This is because most of the output power is provided by the large number of electrons that are emitted when high-velocity electrons return to strike the cathode. The cathode is indirectly heated and is constructed of a high-emission material. The open space between the plate and the cathode is called the INTERACTION SPACE. In this space the electric and magnetic fields interact to exert force upon the electrons. Fig (1) The magnetron structure RECEIVER DESIGN The basic addition to the mobile phone is going to be the rectenna. A rectenna is a rectifying antenna, a special type of antenna that is used to directly convert microwave energy into DC electricity. Its elements are usually arranged in a mesh pattern, giving it a distinct appearance from most antenna .A simple rectenna can be constructed from a schottky diode placed between antenna dipoles. The diode rectifies the current induced in the antenna by the microwaves. Rectennae are highly efficient at converting microwave energy to electricity. In laboratory environments, efficiencies above 90% have been observed with regularity. Some experimentation has been done with inverse rectennae, converting electricity into microwave energy, but efficiencies are much loweronly in the area of 1%. With the advent of nanotechnology and MEMS the size of these devices can be brought down to molecular level. It has been theorized that similar devices, scaled down to the proportions used in nanotechnology, could be used to convert light into electricity at much greater efficiencies than what is currently possible with solar cells. This type of device is called an optical rectenna. Theoretically, high efficiencies can be maintained as the device shrinks, but experiments funded by the United States National Renewable Energy Laboratory have so far only obtained roughly 1% efficiency while using infrared light. Another important part of our receiver circuitry is a simple sensor. This is simply used to identify when the mobile phone user is talking. As our main objective is to charge the mobile phone with the transmitted microwave after rectifying it by the rectenna, the sensor plays an important role. The whole setup looks something like this. THE PROCESS OF RECTIFICATION Studies on various microwave power rectifier configurations show that a bridge configuration is better than a single diode one. But the dimensions and the cost of that kind of solution do not meet our objective. This study consists in designing and simulating a single diode power rectifier in hybrid technology with improved sensitivity at low power levels. We achieved good matching between simulation results and measurements thanks to the optimisation of the packaging of the Schottky diode. Microwave energy transmitted from space to earth apparently has the potential to provide environmentally clean electric power on a very large scale. The key to improve transmission efficiency is the rectifying circuit. The aim of this study is to make a low cost power rectifier for low and high power levels at a frequency of 2.45 GHz with good efficiency of rectifying operation. The objective also is to increase the detection sensitivity at low levels of power. Different configurations can be used to convert the electromagnetic wave into DC signal, the study done in showed that the use of a bridge is better than a single diode, but the purpose of this study is to achieve a low cost microwave rectifier with single Schottky diode for low and high power levels that has a good performances. This study is divided on two kind of technologies the first is the hybrid technology and the second is the monolithic one. The goal of this investigation is the development of a hybrid microwave recti fier with single Schottky diode. The first study of this circuit is based on the optimization of the rectifier in order to have a good matching of the input impedance at the desired frequency 2.45GHz. Besides, the aim of the second study is the increasing of the detection sensitivity at low levels of power. SENSOR CIRCUITRY The sensor circuitry is a simple circuit, which detects if the mobile phone receives any message signal. This is required, as the phone has to be charged as long as the user is talking. Thus a simple F to V converter would serve our purpose. In India the operating frequency of the mobile phone operators is generally 900MHz or 1800MHz for the GSM system for mobile communication. Thus the usage of simple F to V converters would act as switches to trigger the rectenna circuit to on. A simple yet powerful F to V converter is LM2907. Using LM2907 would greatly serve our purpose. It acts as a switch for triggering the rectenna circuitry. The general block diagram for the LM2907 is given below. Thus on the reception of the signal the sensor circuitry directs the rectenna circuit to ON and the mobile phone begins to charge using the microwave power. CONCLUSION Thus this paper successfully demonstrates a novel method of using the power of the microwave to charge the mobile phones without the use of wired chargers. Thus this method provides great advantage to the mobile phone users to carry their phones anywhere even if the place is devoid of facilities for charging. A novel use of the rectenna and a sensor in a mobile phone could provide a new dimension in the revelation of mobile phone.

The Use of Symbolism in The Lottery by Shirley Jackson Essay -- Lotter

The Use of Symbolism in The Lottery by Shirley Jackson In "The Lottery," Shirley Jackson uses symbolism to make us aware of the pointless nature of humanity regarding tradition and violence. The story starts off on a beautiful summer day in a small town. The author describes the day as very euphoric but strikes a contrast between the atmosphere of the town and the atmosphere of the people gathered in the square. The atmosphere is subdued, where the children are "gathered around quietly." The black box is the central theme or idea in the story. It symbolizes at first some type of mystery, but as we read the ending we realize that it is synonymous with doom. Someone's fate lies in an inanimate object, the black box. We do not always enjoy change, even if it might prove beneficial to us. The box is symbolic of our loathing of change; it is old and splintered showing that we cling to what is familiar rather than change and it also symbolizes the traditions of the community. No one in the little town questions the origin of the black box, but accept it as an intrical part of their lives. There is always discussion of people getting a new box, but no one ever really goes through with it. "Everuy year, after the lottery, Mr.Summers began talking again about a new box, but every year the subject was allowed to fade off without anything's being done". The lottery itself is symbolic of the paradox of the human psyche between compassion on one hand and the thirst for violence and cruelty on the other. An example of this is when the children are enjoying a break from school, playing and being children, and suddenly they are being joined by "rational" adults in stoning a mother to death. It appears that tradition has blinded these people in an irrational way, making them unable to think of a reason why this possibly should not be happening. When forced with the possibility of death, human nature in all its complexity, comes down to one instinctive urge, that of survival. When Tessie was in no danger she was gossiping with the other ladies and even encouraged her husband to go and pick a piece of paper. When Tessie wins the lottery; she pleads for another chance and screams for mercy. She demands that her daughters take their chances as well, which is indicative of regression toward our ... ...in. They chose this method of sacrifice in order to yield themselves from the responsibility and burden of murder. Even though the towns lottery has lost all traditional value the sacrificing has held steadfast. As it says in The Lottery ? although the villagers had forgotten the ritual and lost the original black box, they still remember to use the rocks.? This quote means that even though their tradition has gone off course they will always hold to their beliefs about sacrifice. To summarize they held true to their beliefs because of apprehension. So tradition has subconsciously made the community unaware of their horrible actions. The citizens of the village are not afraid of change. They are afraid of what change will bring. The present community has never known a year without the lottery or depleted crops. They fear if they if they disband from the traditional sacrifice their crops will fail. Also their warm safe homes will fade away and the dampened caves that have become so fictional to them will appear to be realistic problems. Works Cited: Jackson, Shirley. "The Lottery." The Lottery.

Graduation Speech: Our Next Big Climb :: Graduation Speech, Commencement Address

Class of 2012, we've finally made it, but not without the help of our parents, teachers and mentors along the way. Maybe what they did for us was that they were a good rudder and we're the ship, and they got us to the sea where we remember who we are. Because we all get in that fog, where we forget who we are or what we're about, we get overwhelmed. I mean I've been there plenty of times in my life. But we're not going to remember most of our lives until the end. But we will remember certain moments. Maybe it's our first 4.0 report card, maybe it's our first 100 percent biology test, maybe it's our first homerun, our first touchdown. Whatever it may be, it will stay with us forever. Many of us have been together through elementary, middle and high school, and we have all had to work hard and remain focused to be where we are today. All change happens in a minute. Your life changes in a moment. Something triggers you and you finally make a decision and it all shifts. As years go by, y our body is going to change, your relationships are going to change, your attitude is going to change. Change is automatic, but progress is not. Our progress has brought us here tonight, and tonight will become one of those moments that we will cherish forever. I have been in the martial arts for about 12 years now, and I remembered my martial arts instructor, Mr. Charles Pearson, sitting everybody down during a black belt testing and telling us, "Earning a black belt is very much like climbing a mountain. You work hard, and eventually you'll work your way up to the top. But once you're there, your journey is not over; it simply has just begun. And you realize that there are other mountains for you to climb." As I now reflect back, I realize that school is very much the same. Our first mountain was a long, yet a fun, 12-year climb. Like all of the other unforgettable moments, this climb, in about 90 minutes or so will come to an end. We have finally reached our high school mountain top, and for a lot of us our next big climb may be to go to college. And for some of us, our next big climb may be to get a job, to travel around the world, start a new business, or even a career.
