Itanium CPUs free essay sample

A paper which introduces Itanium Companys new software design, a concept called EPIC. The paper shows how Itaniums design, the product of a partnership between Intel and HP, revolves around on a concept called EPIC (explicitly parallel instruction computing). It explains that all modern CPUs have some capacity of running multiple instructions from memory simultaneously. Most CPUs are looking for convenience to process instructions in parallel. The paper describes how EPIC shifts efficiency for this analysis from the CPU hardware to the programming language compiler used to effect the application. The paper describes how Intels niche marketing campaign came about when the company realized Itaniums effectiveness of floating-point math and data handling something which is used in a variety of things ranging from encryption to digital video encoding. The Itanium processor owes a lot of its approved performance capability to the fact that the CPU, like a RISC processor, has few supervisor circuits to slow it down with the need to identify resource conflicts. We will write a custom essay sample on Itanium CPUs or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the case of Itanium, this becomes the responsibility of the compiler. While most other CPUs in general use do parallel processing behind the programmers back, Intel and Hewlett-Packard make use of what Intel calls explicitly parallel instruction computing. With EPIC architecture, the instruction set count on the programmer to grant hints about branch optimization, loop optimization, and memory access. This means lesser transistors expended on cycle-consuming supervisors, which means more transistors on the chip to do more concrete.

Scelidosaurus - Facts and Figures

Scelidosaurus - Facts and Figures Name: Scelidosaurus (Greek for rib of beef lizard); pronounced SKEH-lih-doe-SORE-us Habitat: Woodlands of western Europe and southern North America Historical Period: Early Jurassic (208-195 million years ago) Size and Weight: About 11 feet long and 500 pounds Diet: Plants Distinguishing Characteristics: Bony plates and spines on back; quadrupedal posture; horny beak About Scelidosaurus As dinosaurs go, Scelidosaurus has a fairly deep provenance, popping up in the fossil record at the start of the Jurassic period, 208 million years ago, and persisting for the next 10 or 15 million years. In fact, this plant-eater was so basal in its features that paleontologists speculate it may have given rise to the family of dinosaurs, the thyreophorans, or armor-bearers, that included both the ankylosaurs (typified by Ankylosaurus) and stegosaurs (typified by Stegosaurus) of the later Mesozoic Era. Certainly, Scelidosaurus was a well-armored beast, with three rows of bony scutes embedded in its skin and tough, knobby growths on its skull and tail. Whatever its place on the thyreophoran family tree, Scelidosaurus was also one of the first ornithischian (bird-hipped) dinosaurs, a family that included pretty much all of the highly specialized, herbivorous dinosaurs of the Jurassic and Cretaceous periods, with the exception of sauropods and titanosaurs. Some ornithischians were bipedal, some were quadrupedal, and some were capable of walking on both two and four legs; although its hind limbs were longer than its forelimbs, paleontologists speculate that Scelidosaurus was a devoted quadruped. Scelidosaurus has a complicated fossil history. The type specimen of this dinosaur was discovered in Lyme Regis, England, in the 1850s, and forwarded to the famous naturalist Richard Owen, who accidentally erected the genus name Scelidosaurus (rib of beef lizard) instead of the Greek construction he intended (lower hind limb lizard). Perhaps embarrassed by his mistake, Owen promptly forgot all about Scelidosaurus, even though its quadrupedal posture would otherwise have confirmed his early theories about dinosaurs. It was up to Richard Lydekker, a generation later, to pick up the Scelidosaurus baton, but this eminent scientist committed his own blunder, mixing up the bones of an additional fossil specimens with those of an unidentified theropod, or meat-eating dinosaur!

Warranties Assignment Example | Topics and Well Written Essays - 250 words

Warranties - Assignment Example Goods are movable commodities that can be identified at the time of contract, excluding money, securities, and things in action. A merchant is a party who deals in goods of a particular type and professes knowledge of the goods. UCC requirements are different for merchants and non-merchants by stipulating higher-level responsibility for merchants than for non-merchants. Disclaimer of warranties to condition and usage are for example easier for a non-merchant than for a merchant because of a merchant’s expected knowledge of the goods (Mann & Roberts, 2013). Purchase of a hot tub and payment for permit acquisition, upgrade of system, and site preparation is partly applicable to UCC rules. Contract for purchase of the tub is applicable while the contracts for the other deliverables are not. Scope of UCC contracts that excludes services and treatment of the deliverables as different contracts would help in the analysis (Mann & Roberts, 2013). A personal initiative that involves investigating a seller’s background information is the way to distinguishing between merchants and non-merchants on e-bay. This is because the forum operates like an open market where both merchants and non-merchants exist without a formal

Factors of production and circular flow of income Coursework - 1

Factors of production and circular flow of income - Coursework Example This assumption is made in order to facilitate deductions from theories, holding all except one variable constant. For example the demand curve is drawn holding all factors affecting demand, except price, constant. (Wessels, 2006) Economics is built upon three concepts of scarcity, choice and opportunity cost. Scarcity refers to unlimited wants and limited resources that involve making a choice as resources need to be allocated in alternative uses. All economic agents face the basic economic problem and the choices they make involves a tradeoff. (Wessels, 2006) Economics can be divided into two parts that is Microeconomics and Macroeconomics. Microeconomics deals with individual units such as households, firms, markets etc. for example individual demand for bicycle in the economy, or market demand for cars. On the other side Macroeconomics deals with aggregates and the economy as a whole, i.e. what determines the price of all goods. For example aggregate demand for all goods and serv ices in the economy. (Wessels, 2006) Analyses in economics are based on positive and normative statements. Positive statements refer that can be checked against evidence for example an increase in interest rates encourage savings. While normative statements refer to what should be , for example firms should be encouraged to invest. (Wessels, 2006) Factors of Production Land refers to natural resources that are created by nature and not those earning assets created by man. Labour refers to the physical and mental ability of a human provided to a firm. It includes the part of human population that is willing to provide to economics production. Capital that is also called as ‘reproducible capital’ that is the sum of earning asset created by man, while the last Entrepreneur is the risk taker and organizes other three factors of production. (Mokyr, 1985) There are certain characteristics of different factors of production but two common characteristics in all includes that a ll factors of production are limited in amount and they have alternative uses as well. At any point in time one can increase the amount of land, capital and labour it has but it important to note is that it is finite and cannot increase beyond its fixed a capacity. More over these factors of production can be used to produce many different goods and services and hence are substitutable and interchangeable at many levels. This helps one to decide what, how and for whom to produce. (Goldberg, 2000) Characteristics of labour are important in determining wages and volume of production. Firstly labour is a human factor and the active factor. It has its own will to do anything, likes dislikes and so needs to work along with other factors in production. Also labour is different in efficiency, skills, also is mobile and perishable. Each labour has different efficiency and can be moved between jobs. Quality of labour can be improved by improving its productivity by training, educating workfo rce and by providing them better medical facilities. (Marshall, 2007) Land is the primary and passive factor of production as it is the basis from which production starts and it cannot do anything itself as it has be operated by labour. It could be used in multiple ways such as for agriculture; setting up factory but it

Transient Over Voltages Analysis In Power System Engineering Essay

Transient Over Voltages Analysis In Power System Engineering Essay Transient over-voltage is one of main causes for unscheduled interruption in power transmission and distribution systems including a smart grid. A surge over-voltage due to lightning and switching operation results in damages in an electrical power system and often leads to power outages. Predictive calculations of over-voltages generated by the lightning and the switching operation in the transmission and distribution systems are most essential for an economical insulation design and a reliable operation of the transmission and distribution systems. The transient over-voltage can be high frequency, medium frequency or low frequency. The transient over-voltage is dangerous to both lines as well as the connected equipment and may cause damage to the equipment. This project analyzes the transient at the load after switching. This project will discuss about analyzing a transient over-voltages which is the cause and the effect of the transient over-voltages. The method to solve this tran sient over-voltages also been discussed in this project. The PSCAD simulation is used for the transient analysis in this project to design the power system circuits. Problem Statement Voltage transient in Electric Power System appear several disturbances, sometimes very dangerous for the electrical equipment life, for the environment and for the human life. Switching transient phenomena produce in Power Systems over-voltages, over-currents and electrical fields, which havent to neglect. Thus was modeling and simulated the switching transient phenomena, consequently the electric fields and the possible negative influence about electrical equipment, environment and human life. Voltage transient in power system are cause by switching operation, lightning and faults in the system. The over-voltages can be dangerous to both the lines as well as the connected equipment and may cause damage to the equipment. Purpose of this project is to analyze the transient over-voltages at the load and to identify the method to reduce the effect of transient over-voltages. 1.2 Project Objective The objective of this project is as follows: Identify the effect and the cause of transient over-voltages and also the method to solving transient over-voltages. Simulate the transient over-voltages at the load after switching and design the power system circuits by using PSCAD simulation. Analyze the result after switching and after use pre-insertion resistor. 1.3 Project Scope In order to achieve the objective of this project, there are several scopes had been outlined as follows: Analysis on the distribution system. Generating the transient over-voltages waveform by using PSCAD simulation. The analysis is just focusing into transient over-voltages that occur because of the switching capacitor. Chapter 2 2.0 Literature Review 2.1 Introduction Voltage transients in power systems are caused by switching actions, lightning and faults in the system. Different phenomena create different types of transients. Oscillatory transients are caused mainly by switching phenomena in the network. The most common switching action is capacitor bank switching. The most severe transients are caused by capacitor energizing while capacitor de-energizing only causes a minor transient. Oscillatory transients are characterized by duration, magnitude and spectral content. There are subclasses of oscillatory transients depending on the dominant frequency. In this project it will more focus on switching devices. 2.2 Power System Electric power system is a very important part of the infrastructure of modern society. The power system today is very complex interconnected network. Electric power system is the system that can transform and change the form of the energy into electrical energy and transmit it to consumer. Technology today still cannot store the electricity that has been produced. The electrical energy only produce when needed or it will use after it is produced. As the effect, the management on the electricity becomes hard and difficult. The power system may be subdivided into the four major subsystems which are Generation subsystem, Transmission subsystem, Distribution subsystem and utilize subsystem. Figure 2.1 shows the power system that divided into generation, transmission and distribution. Figure 2.1: The Electric Power System 2.2.1 Generation Subsystem There are two major components in the generation system which is generators and transformers. For generators, an essential component of power systems is the three phase alternating current, ac, generator known as synchronous generator or alternator [1]. The source of the mechanical power, commonly known as the prime mover, may be hydraulic turbines, steam turbines whose energy comes from the burning of coal, gas and nuclear fuel, gas turbines, or occasionally internal combustion engines burning oil [1]. Some alternate sources used are solar power, geothermal power, wind power, tidal power and biomass. The power transformer transfer power with very high efficiency from one level of voltage to another level [1]. The transformer is been used to step up or step down the voltage. Insulation requirements and other practical design problems limit the generated voltage to low value, usually 30 kV. The step up is used for transmission of power. At the receiving end of the transmission lines, step down transformers are used to reduce the voltage to suitable values for distribution or utilization. The electricity in an electric power system may undergo four or five transformations between generator and consumers [1]. 2.2.2 Transmission Subsystem An overhead transmission network transfer electric power from generating units to the distribution system which ultimately supplies the load. It also interconnects neighboring utilities which allow the economic dispatch of power within regions during normal conditions, and the transfer of power between regions during emergencies. The network that interconnected between the utilities and load is called system grid [2]. The transmission line can be categorized into two categories which are high voltage transmission line and sub transmission line system. The difference between these two systems is in the voltage where for the high voltage, the level for transmission line voltage can reach 500kV and for sub transmission are in between 69kV to 138kV. All the transmission will be terminated at the substation [1]. 2.2.3 Distribution Subsystem The distribution system connects the distribution substations to the consumers service-entrance equipment. The voltage for this type of system has been reduced by using step down transformer from 66 kV to 22 kV and below. The secondary distribution network reduces the voltages for utilization by commercial and residential consumers. Lines and cables not exceeding a few hundred feet in length then deliver power to the individual consumers. The secondary distribution serves most of the customers at levels of 240 V for single phase and 415 V for three phases. Distribution systems are both overhead and underground. The growth of underground distribution has been extremely rapid and as much as 70 percent of new residential construction is via underground systems [1]. 2.2.4 Utilization Subsystem The utilities system or power system loads are divided into three main categories which are industrial, commercial and residential. Industrial loads are composite loads and induction motors form a high proportion of these loads [1]. These composite loads are functions of voltage and frequency and form a major part of the system load [1]. On the other hand, commercial and residential loads consist largely of lighting, heating, air conditioning and cooking [1]. These loads are independent of frequency and consume negligibly small reactive power [1]. The load varies throughout the day and power must be available to consumers on demand. The daily-load curve of a utility is a composite of demand made by various classes of users. The greatest value of load during 24 hour period is called the peak or maximum demand [1]. 2.3 Transient Over-voltages Transient is a sudden increase in current or voltage in a circuit that can damage sensitive components and instruments. Transient overvoltages are a voltage peak with a maximum duration of less than one millisecond. It can be high, medium, or low frequency. Transient overvoltages on power system are due to various causes and can be classified into two main categories, external and internal overvoltages [3]. Natural overvoltages on low voltage networks are caused by direct lightning strikes. Lightning is an external overvoltage. The high level of energy contained in a direct lightning strike on a lightning conductor or an overhead low voltage line leads to considerable damage of the installation. The overvoltages can be over 20 times the nominal voltage. Operating or switching overvoltages linked to a networks equipment create overvoltages of a lower level 3 to 5 times the nominal voltage but occur much more frequently, thus causing premature ageing of the equipment. Switching overvol tages is an internal overvoltage. Transient overvoltages are generally oscillatory and take the form of a damped sinusoid. The frequency of these overvoltages may vary from a few hundred Hz to a few kHz and it is governed by the inherent capacitances and inductances of the circuit. 2.2 Switching Capacitor Equipment containing electronic switching components is also likely to generate electrical disturbances comparable to over-voltages. The consequences of which on sensitive equipment, albeit not visible, are no less detrimental: premature ageing and unpredictable or fleeting breakdowns. Operating over-voltages are produced when reactive or capacitive equipment is switched on and off. Furthermore, interrupting factory production, lighting or transformers can generate over-voltages which will themselves cause greater damage to nearby electrical equipment. In general, these over-voltages are caused by transient phenomena which appear when the state of the network is changed by switching operation or fault condition. Example of these over-voltages is switching on and off equipment, such as switching of high voltage reactors and switching of a transformer at no load. The time duration of the switching over-voltages is longer than lightning. This overvoltage is most disastrous to the power system equipments because it happen many time than lightning. Closing, opening, disconnection and re-striking in a power system circuit result in over-voltages six times than the normal voltage. Shunt capacitors banks are common devices used in power system for reactive power compensation, voltage regulation and power factor correction. These capacitors are implemented in the system in order to control system voltage, increase power transfer capability, reduce equipment loading, and reduce energy costs by improving power factor of the system. However, energizing these shunt capacitors produces a transient oscillation in the power systems. Due to the fact that the operation of switching shunt capacitors happens frequently, shunt capacitor switching is regarded as the main source of generating transient voltages on many utility systems. These transients can cause damages on both utility systems and customer systems, depending on the system parameters such as switched shunt capacitor size, transformer size, and the type of customer loads connected to the system. Transient frequencies due to utility distribution capacitor switching usually fall in the range 300 Hz to 1000 Hz. Transient over-voltages which result are usually not of concern to the utility, since peak magnitudes are just below the level in which utility surge protection, such as arresters, begins to operate. However, because of the relatively low frequency, these transients will pass through step-down transformers to customer loads. Secondary over-voltages can c ause voltage magnification or nuisance tripping of adjustable-speed drives. Figure 2.2 show the example of single line diagram of the power system using shunt capacitor. Figure 2.3 show the transient voltage at the switched shunt capacitor. This is the example of the transient in the voltage waveform. Figure 2.4 show the transient voltage at the low voltage capacitor that has been magnetized. Figure 2.2: Example of Single Line Diagram of the Power System Using Shunt Capacitor Figure 2.3: Transient Voltages at the Switched Shunt Capacitor Figure 2.4: Magnified Transient Voltage at the Low Voltage Capacitor 2.3 Pre-Insertion Resistor There are several techniques to mitigation the switching transient in the distribution circuit and one of the techniques that use in this project is pre-insertion resistor. A pre-insertion resistor provides a means for reducing the transient voltages associated with the energization of a shunt capacitor bank. The resistors were connected in series with the controlled capacitor bank to damp the transient inrush current. The resistor is bypassed shortly after the initial transient dissipates, thereby producing second transient event. An additional switch is use to bypass this resistor. The performance of pre-insertion resistor is evaluated using both the insertion and bypass transient magnitudes, as well as the capability to dissipate the energy associated with the event and repeat the event on a regular basis. The size for this resistor was calculated from equation 2.1 and 2.2. The optimum resistor value for controlling capacitor energizing transients depends primarily on the capacito r size and the source strength. The value of the resistor is approximately equal to the surge impedance, Zo, from equation 2.3. R = (2.1) Z = (2.2) Roptimum ≈ Z (2.3) Chapter 3 3.0 Methodology 3.1 Introduction This chapter describes about the step that needed in this project. Figure 3.1 show the block diagram of analysis and figure 3.2 show the flowchart of the process analysis. This block diagram shows the step from the first step of the project which is design the circuit to the final step which is result and analysis. Design Circuit Placing Input and Output Devices Running Simulation Result and Analysis Figure 3.1: The Block Diagram of Analysis In order to get the result from the Power System Computer Aided Design (PSCAD), the user should follow the step as follow in the Figure 3.2. Figure 3.2: Flowchart of Process Analysis 3.2 Design Circuit This is the process to build up the diagram of the circuit for the analysis. The user need to choose and selecting component from master library and put it in the main page where the user will construct the circuit. There are many components with a different type of setting. The user only need to double click on the component to edit or changes the setting and parameter. Project development consists of two parts electronic and software designs. Figure 3.2 show the three phase source that use in this project. This source impedance is type R because resistor connected series with the source. The source in this project is being controlled through fixed parameter. Figure 3.2: Three Phase Source Figure 3.3 show the three phase transformer that use in this project. The type of the transformer is a three phase and two winding transformer. The transformer is connected in star delta connection. Other characteristic for the transformer in this project is the transformer use to step up the voltage. Figure 3.3: Three Phase Transformer 3.3 Placing Input and Output Devices This process is used to get the measurement, signal and waveform of the graph in selecting part or component. The output device must be placed at the point of measurement before plotting can be done on the drawing space. Without this device, the PSCAD cannot create the plotting and the result cannot be obtained. After the circuit had already been executed and there is no error, the output from the circuit or diagram will be obtained. Figure 3.4 shows some of the output and input devices that used in this project. Figure 3.4: The input and output devices 3.4 Running Simulation After complete all the circuit design and placing input and output device, the user need to run the circuit to get the result. To run the simulation the user only need to click on the run button in the main toolbar. Figure 3.5 show the location of run button at the main toolbar. The run toolbar have a green color. When this button is pressed, PSCAD will go through several stages of processing the circuit before starting the EMTDC simulation. Figure 3.5: The run button at main toolbar During the run time, the work will be compiling by the PSCAD. The result or output only will produce if there is no error in the setting of the circuit in the drawing or all connection is connected. If there is an error, the warning will appear at output space. Once the program is no error and running, the graph and also the measurement will be produce depending on the selected node. The user also able to pause and zoomed the graph. 3.5 Graph Calculation The graph give the certain value to calculated the overshoot, resonant frequency and also the curve can be identified as an overdamped, underdamped or critical damped. Equation 3.1 is use to calculate the overshoot. Equation 3.2 is uses to calculate the resonant frequency, ωo. % OS = -100 (3.1) ωo = (3.2) The curve is overdamped if ÃŽ ± is bigger than ωo, underdamped if ÃŽ ± is smaller than ωo and critically damped if ÃŽ ± is equal to ωo. Equation 3.3 to 3.8 shows the step to get a value of ÃŽ ±. Figure 3.6 shows the example of the series RLC circuit. Figure 3.6: The Series RLC Circuit Equation 3.3 is equation for series RLC circuit. Equation 3.4 and 3.5 is a root for quadratic equation for 3.3. ( 3.3) (3.4) (3.5) The root for equation 3.4 and 3.5 can be express to equation 3.6 and 3.7. (3.6) (3.7) From equation 3.4 and 3.6, the value for damping factor, ÃŽ ±, calculated as equation 3.8. (3.8) Chapter 4 4.0 Expected Result The transient over-voltages that occur at the load during capacitor switching will be discuss base on result at all buses in the circuit that will be design before doing the simulations. The discussion is about the voltage waveform when transient over-voltages occur and voltage waveform when the simulations using pre-insertion resistors to reduce transient over-voltages. The results of waveform at all buses that will be obtain from PSCAD simulation will be discuss in term of peak voltage, overshoot and weather that waveform is overdamped, underdamped or critically damped. Figure 4.1 show the voltage waveform that will get during capacitor switching at all buses. Figure 4.2 show the voltage waveform that will get at all buses after simulate it using pre-insertion resistor. The transient will be reduce after doing the simulation using pre-insertion resistor. Figure 4.1: Transient Over-voltage Waveform at Buses. Figure 4.2: Voltage Waveform at Buses after Pre-Insertion Resistor. Chapter 5 5.0 Conclusion In PSM 1 all the literature review regarding this project are been studied so at the end of PSM 1 it can be summarized that the objectives of the project will be fulfilled in the next PSM 2, which is to design the circuit, running the PSCAD simulations and analyze the result that obtain from the PSCAD simulations in term of peak voltage, overshoot and weather that waveform is overdamped, underdamped or critically damped. This progress will need more commitment and efforts. In conjunction to achieve that, scope and objectives of this project will be the guideline.

Searching for Peace in Tulips Essays -- Tulips Essays

Searching for Peace in Tulips Throughout the poem â€Å"Tulips† by Sylvia Plath, the author seems desperately searching for peace and tranquility, and instead finds everything she despises, symbolized by the tulips she received as a get-well present.   The hospital setting, in which she is â€Å"nobody,† provides a place where she can â€Å"learn peacefulness, lying by myself quietly,† as Plath explains in lines 3-4.   She goes on to describe her room as very white and serene, and within the walls is a temporary escape from all the cares of the world outside, all the â€Å"baggage† she carries in relation to her family.   Then she receives the tulips, which contrast with the white so much that Plath says â€Å"they hurt me† in line 36.   The passage continues in this vein, relating that they â€Å"weigh her down† in line 40, in a similar fashion as her family does.   This is because the tulips make her â€Å"aware of my heart† in line 60, telling her that she is becoming healthy and will have to leave the hospital and again be weighed down by the obligations of the outside world.   The...

After the Ratification of the Declaration of Independence Essay

After the ratification of the Declaration of Independence, establishing the â€Å"united colonies† as Free and Independent States, the Continental Congress set to work on the task of drawing up a document that would provide a legal framework for that Union, and which would be enforceable as the law of the new land. The Articles were written during the early part of the American Revolution by a committee of the Second Continental Congress of the now independent thirteen sovereign states. The head of the committee, John Dickinson, who had refused to sign he Declaration of Independence, nevertheless adhering to the will of the majority of the members of the Continental Congress, presented a report on the proposed articles to the Congress on July 12, 1776, eight days after the signing of the Declaration of Independence. Dickinson initially proposed a strong central government, with control over the western lands, equal representation for the states, and the power to levy taxes. Because of their experience with Great Britain, the 13 states feared a powerful central government. Consequently, they changed Dickinson’s proposed articles rastically before they sent them to all the states for ratification in November 1777. The Continental Congress had been careful to give the states as much independence as possible. The Articles deliberately established a confederation of sovereign states, carefully specifying the limited functions of the federal government. Despite these precautions, several years passed before all the states ratified the articles. The delay resulted from preoccupation with the revolution and from disagreements among the states. These disagreements included quarrels over boundary lines, conflicting ecisions by state courts, differing tariff laws, and trade restrictions between states. The small states wanted equal representation with the large states in Congress, and the large states were afraid they would have to pay an excessive amount of money to support the federal government. In addition, the states disagreed over control of the western territories. The states with no frontier borders wanted the government to control the sale of these territories so that all the states profited. On the other hand, the states bordering the frontier wanted to control as much land as they could. Eventually the states agreed to give control of all western lands to the federal government, paving the way for final ratification of the articles on March 1, 1781, Just seven and a half months before the surrender of Lord Cornwallis and his British Army at Yorktown, October 19, 1781, the victory ended fighting in the War of Independence and virtually assured success to the American cause. Almost the entire war for five long years had been prosecuted by the members of the Second Continental Congress as representatives of a loose federation of states with no resources and reputations. Under the Articles, on paper, the Congress had power to regulate foreign affairs, war, and the postal service and to appoint military officers, control Indian affairs, borrow money, determine the value of coin, and issue bills of credit. In reality, however, the Articles gave the Congress no power to enforce its requests to the states for money or troops, and by the end of 1786 governmental effectiveness had broken down. Nevertheless, some solid accomplishments had been achieved: certain state claims to western lands were settled, and the Northwest Ordinance of 1787 established the undamental pattern of evolving government in the territories north of the Ohio River. Equally important, the Confederation provided the new nation with instructive experience in self-government under a written document. In revealing their own weaknesses, the Articles paved the way for the Constitutional Convention of 1787 and the present form of U. S. government. The Articles were in force from March 1, 1781, to March 4, 1789, when the present Constitution of the United States went into effect. During those years the 13 states were struggling to achieve their independent status, and the Articles of Confederation stood them in good stead in the process and exercise of learning self- government. The articles created a loose confederation of independent states that gave limited powers to a central government. The national government would consist of a single house of Congress, where each state would have one vote. Congress had the power to set up a postal department, to estimate the costs of the government and request donations from the states, to raise armed forces, and to control the development of the western territories. With the consent of nine of the thirteen states, Congress ould also coin, borrow, or appropriate money as well as declare war and enter into treaties and alliances with foreign nations. There was no independent executive and no veto of legislation. Judicial proceedings in each state were to be honored by all other states. The federal government had no judicial branch, and the only Judicial authority Congress had was the power to arbitrate disputes between states. Congress was denied the power to levy taxes; the new federal government was financed by donations from the states based on the value of each state’s lands. Any amendment to the articles required the unanimous approval of all 13 states. In attempting to limit the power of the central government, the Second Continental Congress created one without sufficient power to govern effectively, which led to serious national and international problems. The greatest weakness of the federal government under the Articles of Confederation was its inability to regulate trade and levy taxes. Sometimes the states refused to give the government the money it interstate commerce. The government could not pay off the debts it had incurred uring the revolution, including paying soldiers who had fought in the war and citizens who had provided supplies to the cause. Congress could not pass needed measures because they lacked the nine-state majority required to become laws. The states largely ignored Congress, which was powerless to enforce cooperation, and it was therefore unable to carry out its duties. After the Colonial victory in the Revolutionary War, it became obvious to the Founding Fathers that the original attempt would not be equal to the task of providing the equitable law which they sought. Congress could not force the states to adhere to the terms of the Treaty of Paris of 1783 ending the American Revolution, which was humiliating to the new government, especially when some states started their own negotiations with foreign countries. In addition, the new nation was unable to defend its borders from British and Spanish encroachment because it could not pay for an army when the states would not contribute the necessary funds. Leaders like Alexander Hamilton of New York and James Madison of Virginia criticized the limits placed on the central government, and General George Washington is said o have complained that the federation was â€Å"little more than a shadow without substance. On February 21, 1787, Congress called for a Constitutional Convention to be held in May to revise the articles. Between May and September, the convention wrote the present Constitution for the United States, which retained some of the features of the Articles of Confederation but gave considerably more power to the federal government. The new Constitution provided for executive and Judicial branches of government, lacking in the Articles, and allowed the government to tax its citizens.

Excoriating and Coruscating

Excoriating and Coruscating Excoriating and Coruscating Excoriating and Coruscating By Maeve Maddox Both excoriating and coruscating are verb forms used as adjectives. Excoriating is a hideous word. At least, its meaning is: excoriate (transitive verb): to pull off the skin or hide from (a man or beast) The word retains this literal meaning in the context of pathology to refer to the removal of skin by cutting, abrasion, or corrosion: Gastric secretions leaking around the gastrostomy can result in skin excoriation. Excoriate can also mean to strip bark from a branch or other part of a plant: A tree which does not fructify is often rendered fertile by an excoriation near its root. In general usage, excoriate is frequently used figuratively to mean, â€Å"to upbraid scathingly, decry, revile†: Feinstein excoriates CIA for spying on Senate committee Kerry excoriates Assad regime for ‘inexcusable’ chemical strike Coruscating, on the other hand, is a pretty word: coruscate (intransitive verb): to give forth intermittent or vibratory flashes of light; to shine with a quivering light; to sparkle, glitter, flash. From the Latin verb coruscare, â€Å"to vibrate, glitter, sparkle, gleam,† coruscate and its forms (often misspelled with two r’s) are used to describe lighting effects: now, when the ground was white with snow, and the forest trees covered with ice, and sparkling and corruscating [sic] in the rays of the sun, Nettie would shout with delight below, by the creek, a corruscating [sic] tendril of smoke drifted up through the trees. Figuratively, coruscating describes a lively witty writing style, the kind demonstrated by Oscar Wilde in The Importance of Being Earnest, a play devoid of malice. Ambrose Bierce and H.L. Mencken, on the other hand, made use of a lively, quick-witted coruscating style to excoriate the people and institutions they despised. For this reason the pretty word coruscating and the ugly word excoriating have collided like chocolate and peanut butter in a Reese’s candy ad. A few journalists seem to understand the meaning of coruscating, but a great many use it as if it meant excoriating: Michael Moore’s coruscating attack on the gun culture, Bowling for Columbine. [Julia Gillard] launched a coruscating attack in parliament on opposition leader Tony Abbott Iain Macwhirter launches coruscating attack on Alex Salmond and Rupert Murdoch Betsy Andreu, the wife of Lance Armstrongs former team-mate Frankie, who played a key part in exposing the Texan as a drug cheat, has launched a coruscating attack on the disgraced cyclist. Because of the confused idea that coruscating has something to do with negative comments, the word is frequently paired with review, critique and criticism: The Australian literary critic Clive James manages to produce coruscating reviews like his brutal attack on Dan â€Å"Da Vinci† Brown’s novel Inferno. But the most coruscating criticism came from Ankie Spitzer and Ilana Romana, two of the widows of the Munich Eleven Wow, a coruscating criticism of Sonys PS4 Another possible reason for the frequent misuse and misspelling of coruscate could be that speakers associate it with the meaning and spelling of corrosion. In the interest of saving coruscating to mean sparkling, the next time you want to characterize a verbal attack as extremely scathing, use excoriating. When you do have occasion to use coruscating, remember to spell it with one r. Want to improve your English in five minutes a day?

Essay on The Goals of a Liberal Education

Essay on The Goals of a Liberal Education Essay on The Goals of a Liberal Education â€Å"Only Connect†¦Ã¢â‚¬  The Goals of a Liberal Education This article, which described the author’s perspective of what it means to be liberally educated, broadened my personal view of what a liberal education really is. First of all, the author improved my understanding on the word liberal by originating the word from Latin, Old English, and even Greek. He mentioned that liberal education was a term itself that was being carelessly used nowadays by institutions such as colleges, promising their prospective students a liberal education if they attend. This never came across my mind as I embarked on a search for my desired learning institution not too long ago; however the author has now impacted me in such a way that I can no longer overlook the importance of a liberal education. I was surprised to read the list of the attributes the author expected one who has acquired true liberal education to have. This was because it just seemed like a very broad range of knowledge for someone to have. For example, differentiating soybeans and alfalfa through a single glance at a farmer’s field seemed a bit radical in my opinion. Nonetheless, that is why it is an attribute of a liberally educated person as oppose to an average one. The end of the article proved to be the most significant out of the text in my opinion. In a way, the author goes against what he has spent nearly the whole article talking about, and mentions that â€Å"A liberal education is not something any of us ever achieve;

Why was Microsoft so dominant during the birth of the personal Dissertation

Why was Microsoft so dominant during the birth of the personal computing era and beyond - Dissertation Example ’, this study revealed that the decision of Bill Gates to focus on developing useful software (i.e. Microsoft Office, MS-Word, Excel, and PowerPoint) triggered the success and triumph of this company. By not spending much money in the development of computer hardware, Microsoft was able to easily enter into a business partnership with other companies like IBM as part of making its software products widely accepted by the end-consumers. Despite the ability of Microsoft to dominate the personal computer industry, the primary research findings revealed that there are some IT experts who are not satisfied with the security and software quality offered by Microsoft as compared to other software manufacturers like Mac.

Eassy 1 - Essay Example Therefore intuition and deduction from this information is a priori (Lawhead 22). Rationalism is a perceived truth about something. In an argument by Lawhead rationalism is a feeling of truth about an object or an idea (23). The author further points out that the feeling is accompanied by a general assumption about truth about something (Lawhead 23). Additionally, rationalism is created about a fact that can be proven be fact or a creation. For instance, a person may believe in the belief that God exists because it is a fact that is believed beyond reasonable doubt. In this particular case, the assumption that God exists may be proven but with a strong believe but not with experience. Lawhead points out that rationalism is basically factual theories but with no physical experience or proof (45). On the other hand, empiricism is a theory that can be proven with experience. Lawhead defines empiricism as an idea or theory that is real (56). The vice is different from rationalism which is based on beliefs. Empiricism can be proven by physical evidence. However, there is no source of knowledge on an idea that can prove its existence. The only source on knowledge while using empiricism is experience. For instance, when person undergoes an operation to remove a tumor from their body they experience the medical process but they do not have the chance to see the operation. In this particular case, the person undergoing the surgery does not know the source of the tumor or the process the operation. However, the experience both pain and recovery. In future the person may describe the experience not with specific knowledge of the events but with their experience of the events. This may include the pain they felt, the time they took to recover or the price they paid for the operation. T his is a perfect example of an empirical idea. Lawhead argues that empiricism gives us knowledge more effectively
