George Westinghouse - Essay Example Although his influence on the modern civilization may be unnoticed by many the achievements and inventions associated with Westinghouse's name in some or other way surround us every day. The influence of George Westinghouse was decisive in improving the safety of the US railroad system, stimulation of the transportation industry growth, development of the modern electric distribution system and many other landmark inventions (Jonnes, 2003). The son of a machine shop owner, Westinghouse was the eighth of ten children. His father's machine shop manufactured a variety of industrial and agricultural machinery while Westinghouse Sr. himself was a talented inventor who registered at least seven patents. In 1860, at the age of fourteen Westinghouse Jr. started to work for his father at 50 cents an hour and got the first insights into machinery and metalworking. The Civil War interrupted the early start of his career as an inventor: George Westinghouse joined the Union army at the 15 and although his father forced him back in 1863 George finally received the consent of Westinghouse Sr. to be enlisted in the infantry. After several months Westinghouse Jr. became an engineer in the Union Navy (Dietrich, 2006). The Civil War was over when Westinghouse was only 19 and already at that age he created and patented his first invention, the rotary steam engine (Jones 2003a). After spending three months at tiny Union College, Westinghouse finished his formal education, returned to the machinery of his father's shop, and immediately produced a series of important inventions and engineering innovations. Thus, at age of twenty one Westinghouse invented the famous 'car replacer', a mechanical device to rerail derailed cars back onto the tracks and a mechanical 'frog' to switch trains onto of two tracks (ASME 1937). Although practical success of both these inventions Westinghouse did not gain much in terms of commercial success: his patent protection was not strong enough to prevent the railroads that adopted the replacer and frog from sidestepping his rights. However, Westinghouse considered the bitter experience and did not make the same mistake in the future. Prior to turning his attention to the new and exceptionally promising fields of activity Westinghouse had already become widely known as a successful mechanical engineer, inventor and entrepreneur. The number of patents issued to him during only five years between 1869 and 1873 exceeded 20, and one of them was for one of the most essential inventions of that epoch, namely the air brake (Jonnes 2003). During the next decade, the air brake gained overwhelming acceptance among the railroads but Westinghouse became interested in finding and exploiting natural gas. Although that part of Westinghouse's life is scarcely known and relatively insignificant considering his achievement in mechanical engineering and electricity, during only two years from 1884 to 1885 he applied for 28 patents. His gas inventions included the

Purposes and strategies of Johnson's Great Society program Essay

Purposes and strategies of Johnson's Great Society program - Essay Example To serve aforementioned purpose it was important to form a strategy viable for people living in such a quagmire. During the years of Kennedy it was not explicit that the promised equality of 1863 could be served. Yet Johnsons’ era was indeed remarkable. Johnson being a proponent of equal rights enacted Civil Rights Act of 1964 right after 5 years of Kennedy’s assassination. This act was to ensure implementation of emancipation proclamation of 1863 in spirit. It is pertinent to mention that women rights and gender discrimination was an important agenda of the change. The act prohibited discrimination in institutions like hospitals, schools and public accommodations like hotels, theaters and restaurants. It helped in obliterating the discrimination in employment giving a big blow to economic injustice. It also banned gender discrimination which transformed the society in an entirely new way. The proposed strategy was governmental action to promote welfare. This ‘New Deal’ through Medicaid and Medicare and Equal employment Opportunity Commission, National Endowments and National Public Broadcast Network needed federal funds ultimately completed and extended the agenda. Contortions in status quo caused a well steered civil rights movements and awareness campaigns. Similarly women rights also instigated a social change which directly diffused into American Culture. The Vietnam Campaign caused serious blow to the political ideology that prolonged the war, in fact they surprised the military leader of the US.

Pensions are sums of money paid to an individual regularly in fixed terms after retirement. Retirement plans in United States collaborate with human resource of all companies to ensure that no employee retires without pension. Pensioners are guaranteed both defined benefit and defined contribution pensions. Apple offers pensioners other benefits apart from pension for instance Equity within United States, Fixed and timely income and foreign equity. Paid off times are hours designated for employees to use whenever need arises. These hours are used mostly for sick days, schedule time off and extended absence off. Paid off times are beneficial to operations of the company because they allow individuals overcome fatigue and stress reducing cases of last minute absence and make employees feel satisfied. After every sales increase Apple pays for employees’ holidays though at irregular basis to continue serving customers. Work from home is practice whereby individuals engage in economic activities of their companies while away from job place. This is mainly indulged by agents and senior employees who have required resources at their homes for instance reliable internet and telephones. Apple provides best work at home services because their technical customer advisors are based at their homes and they work for short times but earn good salary. The employee will be able to perform other duties. Flexible hours are periods that employee is scheduled for work but is free to adjust his or her own program to cover for transport, picking children, and child care for breast feeding mothers. Apple allows customers to work according to their schedule for instance one can come early and leave before time or come late and compensate for the lost time. Wellness programs are activities conducted to keep the employee’s bodies, mind and emotions healthy. Wellness programs are for instance motivation talks, drug abuse rehabilitation and weight loss programs. Apple has well equipped gym where employees are free to exercise after job or lunch time and has reduced health related costs. Question 3 A partner for public service is a non-profit organization whose main duty is to ensure employees work according to set standards. Its mission is to shape the way civil servants deal with government duties. Strategic planning is process of integrating current and future goals of an organization by using right process which leads to innovation. Strategies help in creating a nexus between human resource development policies and goals of the organization.

Geomorphology 5 - Lab Report Example us solution while EC measures the degree to which a solution carries an electric current, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. Consequently, the complex nature of the variability calls for a study, which can provide a succinct explanation to the basis of this phenomenon. Data analysis was an important aspect in testing the hypotheses. In which case, data was collected for ph and EC for the different sites and tabulated. The data was then analyzed from drawing graphs for the different variables: pH vs EC, pH vs. site, EC vs. site. This allowed for testing relationship between stream chemistry and position besides testing that between pH and electrical conductivity. Water samples were collected from specified sites: Clarks River, 2: Bee Creek, 3: MCP unnamed trib. In SedSoilHuman Lab, lab Ph meter and EC meter were calibrated. Ph and EC on the water samples were measured. The results show that change in position contributes to the change in stream chemistry (ph and EC). This can be contributed to external factors such as pollutants, surface runoff and soil erosion. These factors vary within a river basin from one point to another. For instance, both factors affect the availability of ions at a given point. Soil erosion carry with it ions from one point to another so do pollutants add ions to their area of destination (Rajvaidya 45). In which case, increase in ions leads to increase in electrical conductivity of a solution (stream) while it leads to reduction in

Racial Disparities in Correction Populations Essay

Racial Disparities in Correction Populations - Essay Example The above information, if given with critical analysis could be used to strongly prove that racial disparities in correction populations exist in the US justice system. It is important to dig on this issue because this could entirely create a significant impact on the US justice system, not only on its national and federal context, but on the entire international setting. The US, as a primary advanced and influential nation on earth, should always ensure it has substantially showed the appropriate example in all aspects especially for humanitarian cause. After all, there is a negative meaning associated with racial disparities and this could be enough at some point to remarkably refute the remarkable image of the US towards fairness in dealing with justice. There are varying opinions and even substantial justifications in line with racial disparities. The proof of these can be considered through various researches and other related studies that could potentially create meaningful ins ights about racial disparities in general. ... Justice systems employ important legal concerns. These legal acts encompass the society, and eventually groups of people. Race involves group of people so it is eventually a social group which is subject of a social construct and that it can only be refined to function well if there is prevailing justice system. Racial disparity therefore is about â€Å"unfair, unjust, unequal or unnecessary care or treatment of group of people† which can be evidently observed through the association of their race with whatever case confronting them (Loue & Sajatovic 2011, p.1260). Correctional populations defined There are varying existing definitions or concepts about correctional populations. However, in the context of the discussion in the prevailing justice system in the United States, the following are individuals that should be considered who belong to the correctional populations: they are incarcerated individuals either in prison, jail or supervised by the community that could be eith er probation or parole (Bureau of Justice Statistics 2012). Correctional populations therefore are composed of groups of people who have to face punishment or consequences of their acts as interpreted and justified by the final authority of the justice system. Evidences of racial disparities in correctional populations There are varying evidences of racial disparities in correctional populations and basically this can be illustrated by understanding the percentage of racial groups represented in a certain population, the number of individuals of a racial or minority groups that are integral parts of the criminal justice system, and many more (Walker,

Advantages of Repeater in Networking

Advantages of Repeater in Networking Router: Routers are devices which connect two are more networks that use similar protocol. A router consists of hard ware and software. Routers operate at a network layer of O.S.I model. Routers use logical and physical address to connect two or more logically separate network. They make this connection by organizing the large network into logical network segment (some times small sub network or sub nets). Each of these sub nets is given a logical address. Data is grouped into packets or block of data. Advantages of Router: They use high level of intelligence to rout data.   Routers can also act as a bridge to handle non rout able protocols such as NetBEUI (Network Bios Extended User Interface) Disadvantages of Router: High level of intelligence takes more processing time which can affect performance Routers are very complicated which installation and maintenance difficult. 2) Gateways: Gateways are devices which connect two are more networks that use different protocols. They are similar in function to routes but they are more powerful and intelligent devices. A gateway can actually convert data so that network with an application on a computers on the other side of the gateway e.g a get way can receive email messages in one format in convert them into another format. Gateway can operate at all seven layer of OSI model. Since Gateway perform data conversion so they are slower in speed and very expensive devices. 3) Repeaters: Repeaters are used within network to extend the length of communication. Data process through transmission media in the farm of waves or signals. The transmission media weaken signals that move through it. The weakening of signal is called attenuation. If the data is to be transmitted beyond the maximum length of a communication media, signals have amplified. The devices that are used to amplify the signals are called repeaters. Repeaters work at the physical layer of OSI model. Repeaters are normally two ports boxes that connect two segments. As a signal comes in one port, it is regenerated and sends out to the other port. Advantages of Repeater: Repeaters easily extend the length of network. They require no processing over head, so very little if any performance degradation occurs. It can connect signals from the same network type that use different types of cables. Disadvantages of Repeaters: Repeaters cannot be used to connect segments of different network types. They cannot be used to segment traffic on a network to reduce congestion . Many types of network have a limit on the number of network s that can be used at once . 4) Bridges: Bridges are used to connect similar network segments. A bridge does not pass or signals it receives. When a bridge receives a signal, it determines its destination by looking at its destination and it sends the signals towards it. For example in an above figure a bridge has been used to join two network segments A AND B. When the bridge receives the signals it read address of both sender and receiver. If the sender is a computer in segment A and the receiver is also segment A, it would not pass the signals to the segments B. It will however pass signals if the sender is in one segment and the receiver in other segment. Bridge works at the data link layer of O.S.I model. Advantages of Bridges: Bridge extends network segments by connecting them together to make one logical network. They can affect the segment traffic between networks by filtering data if it does not need to pass. Like repeaters they can connect similar network types with different cabling. Disadvantages of Bridges:   Bridge possess information about the data they receive with can slow performance. 5) Hub: Hubs are basically multi ports repeaters for U.T.P cables. Some hubs have ports for other type of cable such as coaxial cable. Hubs range in size from four ports up to and for specific to the network types. These are some hubs which are I. Passive Hub II. Active Hub III. Switch/ Intelligent Hub Passive Hub: It provides no signal regeneration. They are simply cables connected together so that the signal is broken out to other nodes with out regeneration. These are not used often today because of loss of cable length that is allowed. Active Hub: It acts as repeaters and regenerates the data signals to all ports. They have no real intelligence to tell weather the signal needs to go to all ports that is blindly repeated. Switch Hub: Switches are multi ports bridges. They filter traffic between the ports on the switch by using the address of computers transmitting to them. Switches can be used when data performance is needed or when collision need to be reduce. Advantages of Hub Hubs need almost no configuration. Active hub can extend maximum network media distance. No processing is done at the hub to slow down performance Disadvantages of Hub   Passive hubs can greatly limit maximum media distance.   Hubs have no intelligence to filter traffic so all data is send out on all ports whether it is need or not. Since hubs can act as repeaters the network using them must follow the same rules as repeaters 6) Modem: The device that converts digital signals into analog signals and analog signals to digital signals is called Modem. The word modem stands for modulation and demodulation. The process of converting digital signals to analog signals is called modulation. The process of converting analog signals to digital signals is called demodulation. Modems are used with computers to transfer data from one computer to another computer through telephone lines. Modems have two connections these are. Analog connection   Digital connection Analog connection: The connection between the modem and the telephone line is called analog connection. Types of Modem THERE ARE TWO TYPES OF MODEMS Internal modem External modem Digital connection: The connection of modem to computer is called digital connection INTERNAL MODEM: It fits into expansion slots inside the computer. It is directly linked to the telephone lines through the telephone jack. It is normally less inexpensive than external modem. Its transmission speed is also less external modem. EXTERNAL MODEM: It is the external unit of computer and is connected to the computer through serial port. It is also linked to the telephone line through a telephone jack. External modems are expensive and have more operation features and high transmission speed. Advantages of Modem Inexpensive hardware and telephone lines. ii. Easy to setup and maintain. Disadvantages of Modem i. Very slow performance.
