Cheap Essays vs Expensive Essays

Cheap Essays vs Expensive Essays Cheap Essays vs Expensive Essays Cheap essays refer to the essays that can easily be bought by customers when required. They are easily available for the customer’s disposal; therefore, the customers have the opportunity to buy as many essays as possible. Based on this school of thought, it is common for the customers to prefer companies that offer cheap essays given the wide opportunity available to buy as many essays as possible. An expensive essay refers to the essays that are very costly to buy or acquire. In this case, any customer wishing to buy an expensive essay will only be able to buy very limited number of essays since he or she is unable to meet the costs of purchasing many essays. It is notable that reduction of the essay cost may translate to many essays being bought by customers based on a theory of demand. This theory states that the higher the price the less the demand, and the less the price the higher the demand. This is to imply that reduction of the essay costs will attract many more clients who may buy the essays from the company due to cost effectiveness for the customers. The rationality behind this is that most customers will prefer to write their own essays as opposed to buying very costly or expensive essays. However, there is another deciding factor for choosing to purchase either the cheap or expensive essays. This is whether or not the essays are written by professionals, and the level of quality that they display. It is notable that not all writing company services are cheap and may depend on whether the company has professional writers with a lot of experience, as opposed to writers with fewer qualifications and experience. The type of management of the company will always detect the quality of essays being offered and the cost that comes along with it. Some companies have certain cultures that are implemented within the organization as far as writing is concerned. This kind of culture will shape the direction and nature of the essays being written. If a company is able to recruit professionals writers at a cheaper cost, then this company is able to offer cheaper essays. In this scenario the company’s essays will tend to be in high demand by most customers. However, if the company does not produce high quality essays then the customers may prefer to buy an essay at a higher cost to get a better service. A rational person will always go for quality products to suit his or her needs; therefore, it may be usual for the customer to buy a fewer number of essays at a higher price than poor quality essays at a lower price. provides cheap custom essays of the highest quality. All essays are written by top-rated academic writers with PhD and MA degrees. We guarantee non-plagiarized papers!

Reducing the lifecycle cost of oil and gas facility by use of Essay

Reducing the lifecycle cost of oil and gas facility by use of simulation - Essay Example During operations, oil and gas industries incur lifecycle costs that affects their production capacity and cost of production. Lifecycle costs include recurring and other nonrecurring costs incurred by a company during a certain operational period. Oil and gas companies incur lifecycle cost through installation of new facilities, maintenance, and upgrading of the existing facilities. Facilities in the companies have definite life span and therefore the companies experience an additional when closing them down With these costs to consider, the companies are concerned with the possible alternatives to cut or reduce the effects of the lifespan cost. In order to eliminate or minimize lifecycle cost, oil companies rely on planning making simulations a useful tool. Simulations are models applied by the companies to determine the viability of a facility before its inception (Gorski, 2006). This paper therefore analyzes the benefits achieved from application of simulations in the reduction o f lifecycle cost in oil and gas companies. Some of the ways in which simulation is applied to reduce lifecycle cost Evaluation and comparison of different approaches for replacement Evaluation and comparison of alternative strategies for product use Evaluation and comparison of different designs Optimal allocation of available funds of activities in the process of product development During their lifespan, most companies are confronted with situations where they need to make important decisions on whether to close down a facility or to change a business strategy. In such situations, the companies experience lifecycle costs that affect their production. Such companies can apply simulation models to determine whether they need to close down the existing facility or they need to improve its efficiency. Using simulations the managers of the affected companies can determine whether they need to adopt a new business, strategy or to modify the existing strategy to fit their operations. Sec ondly oil and gas companies continuously retire old facilities as they install new facilities, these processes costs the company a lot of money and therefore the companies need to make appropriate decision. Simulations come in as the most appropriate tool that the companies need apply when making strategic management and operational decisions. Using simulation models strategic managers of a company are able to evaluate benefits from alternative decisions. With simulation models, managers can determine decisions and solutions that best fits their companies. Simulations therefore enable the companies to reduce uncertainty when making important decision that concerns their operation. Companies in the oil and gas industry always have new projects intended to improve their operations and facilities. The new facilities rely heavily on designs and therefore the companies are always on the lookout for the most appropriate design. The companies need to evaluate the suitability of these desig ns before choosing the most appropriate design (Petra, 2004). Using simulation models, companies can determine the most appropriate design from the possible choices. The companies also need to choose the most efficient design from the available possibilities; this requires data analysis and projections that cannot be achieved without the real facility. However, with simulations strategic managers of the companies are able to determine and evaluate the efficiency of such models through an analysis simulation models data (Lanner, 2008). Before launching a new product into the market or initiating a project, oil and gas companies need to evaluate their economic viability. In this process, simulation models stands out as the most appropriate tool for application. Using the models, companies are able to predict the market’s response towards a new product. Companies such as Shell Company use ADENT simulation techniques to evaluate the viability of its new products in potential mark ets. The tool is

Sex Crime Essay Example | Topics and Well Written Essays - 1500 words

Sex Crime - Essay Example "After a three-year period of consultation with those dealing with crimes and sexual offences, the Sexual Offences Act 2003 came into force on 1 May 2004" (The Office for Criminal Justice Reform, 2006, p.12). The sexual offences act, 2003 has revealed a detailed discussion as regards consent in regard to rape. The Law Lords overturned this common law idea that marriage means a man has a 'continual' consent from his wife for sexual activity at any time (R v. R [1992]). Thomas (2005) describes as "[t]his was later brought into statute in 1994, now in Sexual offences Act 2003" (p.11). The present paper is intended to justify whether the guidance of consent as provided in the said enactment is proper or warrants further explanation and amendment. The Sexual Offences Act, 2003 has been designed to make the process easier and convenient for prosecuting people who use physical force to others for having sex despite the unwillingness of the other party. The legislation provides that a person would not be charged with the offence if he or she intends to protect a child from sexually transmitted infection, from physical safety of the child or from becoming pregnant. The Sexual Offences Act 2003 has made a greater legal protection for victims by clarifying the law on consent. Section 1 of the Act states, a person commits an offence of rape if he intentionally penetrates to the vagina, anus or mouth of another person despite her reluctance. The phraseology "reasonable belief" as enunciated in section 1 is determined in regard to the particular context of a given circumstance. Section 74 of the Act defines consent as stating that a person is presumed to give consent if he agrees by choice, and has the freedom and capacity to make tha t choice. Section 75 provides a list of circumstances where it may be considered that the victim or complainant did not consent to the said sexual interaction. From a perusal of section 76, it is clear that if (a) the defendant intentionally deceive the complainant as to the nature or purpose of the relevant act; or (b) the defendant intentionally induce the complainant to consent to the relevant act, it is presumed that the victim did not give his or her consent. As per the provisions of section 79(2) penetration is a continuing act from entry to withdrawal and if the victim consents to penetration but withdraws consent after penetration, the accused must withdraw his penis immediately.Consent in the sexual offences ActConsent must be obtained peacefully and without the use of force or violence. If it is obtained by force, threat or inducement or any other unlawful means, said consent would be declared as void and illegal. The meaning of the term "consent" as given in the Sexual offence act, 2003 is an aiding tool for the juries in deciding whether the victim was able to give or did actually give his or her consent to the said sexual transaction. In this connection, the defendant must show that his belief in consent was reasonable and obtained in due manner and a jury must consider all the circumstances including any step which he has taken to ascertain in determining whether the vi

The report gives details as to the importance of human resource planning in the city. According to the report the overall structure has expanded in a very complex manner, with salaries, the work staff, number of unions in the community, and departments all in a very haphazard and complex manner, thereby each of them need an effective human resource planning strategy in order to enable them working in the due manner desired. With factors like considerable amount about to retire by 2005, strategy needs to be devised in order to create their replacement and fill up for the vacuum that would be created afterwards. The aim behind the entire idea is to create a model community in Canada through the usage of human resource functions. Technology and information system means are adopted for this purpose to facilitate the overall process of community improvement. The idea is to convert the above stated equation into a relationship that serves the needs of the community. The enables and stakeholders in this case are the top heads in form of Mayor, managers, councils, the citizens, the entire scheme of plan, human resources and most importantly

Diagram For Five Bus Power System Computer Science Essay

Diagram For Five Bus Power System Computer Science Essay The main objective of this project is to analyse the different parameters of five bus bar power system. Analysis of these bus bars parameters must be supported by both theoretically and simulated results obtained by using Power World Simulator (PWS). Power World Simulator (PWS) used for engineering analysis, power system visualisation, simulation and analysis tool [1]. In this project five bus bars attached to each other according to their specific input data. According to power system terminology, bus is the node at which two or more different devices joined known as buses. In electrical power distribution, bus bar thick strip that conduct electricity to other electrical apparatus [2]. In this project, input data for five bus power system provided and the required power system designed on the Power World Simulator as per requirement. When five bus power systems designed on PWS instructions completely followed in order to make required design. After that one-line diagram is obtained shown in figure 1. Then design critically analysed by performing simulation in order to check voltages and flows on other network components. Figure 1: One-line diagram for five bus power system 2. Problem Analysis When designing five bus bar power system different problem were faced because designing is quite complex and skilled operation. 2.1 Data analysis Before start designing in order to draw one-line diagram input data for buses were properly analysed and also transmission line data and transformer data. As four variables associated with each bus: voltage magnitude Vk, phase angle ÃŽ ´k , real power Pk, and reactive power Qk. By these variables analyse which were input data and which were unknown from the provided input data. 2.2 Designing analysis In designing, general designing principles were followed in order to design five bus power system. The five-bus power system modelled in Power World Simulator (PWS), this software used for power system analysis. Although some guide provided to start modelling the five-bus power system in PWS. Modelling was quite complex and take several times because of different adjustment and given parameters was properly entered for buses, transmission lines, and transformers in order to simulate model properly. After completing the required model on PWS, power flow can be visualized and also other parameters that were unknown when simulation performed. 2.3 Software analysis According to the main objective of the project mainly focused on the modelling as per requirement and five-bus power system modelled on the Power World simulator for the purpose of simulation. This software requires some technical skills. Thats why general principles must follow in order to simulate the desired model otherwise problem might occur. 3. Problem Solutions 3.1 Data solution The one-line diagram can obtain by inserting the bus data, transmission line data and transformer as per requirement for the five-bus power system. The bus input data enable to distinguish between different kinds of buses. These buses are as follows: Slack bus ( V and ÃŽ ´ input data) Load bus (P and Q input data) Voltage controlled bus (P and V input data) Similarly transmission line input data provide series resistance, reactance, and shunt charging, transformer input data provide series resistance and reactance. With the help of these input data one-line diagram can be achieved by using the software. 3.2 Designing solution The required model designed on Power World Simulator which permits the system to perfectly model as single phase system. The connection between devices drawn by a single line in order to join them, therefore one-line diagram achieved. The desired model has five buses and by available input data for all devices model can be achieved by inserting all devices parameters properly. Make sure that all the devices connected to each other, otherwise its impossible to achieve the required results. In PWS, generator have circle shape with a rotor at the centre, large arrows represent the load and transmission line represented by simple line. By following the general principles required one-line diagram can be achieved. 3.3 Software solution Five-bus power system modelled on PWS as per requirement and then simulation performed to determine the unknown variables. By this software different techniques like Gauss-Seidel and Newton-Raphson techniques can be performed. By PWS, Y bus (Bus Admittance Matrix) can be easily obtained and compare with theoretical values of admittance matrix. PWS has some different and interesting specification if compare with MATLAB and Proteus. Simulation can easily perform by PWS but make sure that all the given parameters properly inserted. 4. Implementation The main objective of this project to analyse the five-bus power system that means to critically analyse the parameters for buses, transformers, and transmission lines. These parameters can be determined theoretically by performing different theoretical techniques but the result obtained have some human error and time consuming, thats why in order to remove these error Power World Simulator used. By following the modelling analysis and solution, implementation of five-bus power system can be achieved by using the software Power World Simulator (PWS). PWS used in order to compare both simulated and theoretical results. Power World Simulator has two modes, Edit mode and Run mode. Edit mode used to add buses, load and many other components as shown in figure 4.1 Figure 4.1 As this project based on Power World Simulator as per requirement and by following the bus input data totally five buses inserted in order to full fill the requirement. In the Edit mode, five buses inserted to desired location. All buses parameters set as provided and adjusted in Bus Field Options dialog and there are three load buses, one slack bus, and one voltage control bus. Between bus1 and bus5 transformer line connected and similarly between bus4 and bus3. This can be done graphically by selecting insert, transformer. Buses 2, 4 and 5 connected by line, all these line have different parameters, line series resistances, series reactance and MVA limit inserted in the line information dialog. The required model has two generators one on slack bus1 and other on voltage control bus3, and also two loads, one load inserted on bus2 and other load inserted on voltage control bus3. Parameters for buses, transmission lines and transformers properly set as given. By following all these pr inciple required one-line diagram obtained as shown in figure 4.2 Figure 4.2 Power World Simulator also has other mode, Run Mode which is used for the simulation. When simulation performed all the unknown values appeared on the screen. The arrows show the direction of power flow as shown in figure 4.3. On this final model different technique and changes performed as per requirement. Figure 4.3 5. Results and Discussions After completing the one-line diagram on Power World Simulator simulation performed. Through simulation all the unknown values determined and these parameters shown in table 5.1 Table 5.1 After that Y-matrix can be easily displayed in PWS by selecting case information, solution details, Y-bus. The Y-bus derived by other system parameters which cannot be change directly. These simulated values compare with the theoretical values. Y-bus matrix shown in table 5.2 Table 5.2 Theoretical values for Y-bus admittance matrix elements are given below: Off diagonal elements: Y42 = Y24 = 089276 + j 9.91964 Y52 = Y25 = 1.42284 + j 15.8714 Y51 = Y15 = 3.72 j 49.72 Y54 = Y45 = 2.8568 j 31.7428 Y43 = Y34 = 7.458 j 99.44 Diagonal elements: Y11 = 3.72 j 49.7 Y22 = 2.3211 j 25.791 Y33 = 7.458 j 99.44 Y44 = 11.21 j 121.25 Y55 = 8.0053 j 97.324 The theoretical values compare with the simulated values as obtained in table 5.2 almost same result obtained. After computing the Y-matrix, Gauss-Seidel and Newton-Raphson techniques apply in Power World Simulator in order to solve the power flow problem and compare the solution obtained by PWS. PWS gives the calculation by default Gauss-Seidel technique, so the bus record table 5.1 shown above is the solution for Gauss-Seidel. The solution computed by Newton-Raphson technique shown in table 5.3. Table 5.3 After computing the solutions from both the techniques and compared with each other. It observed from both the results that there was not much difference in both results except in generated reactive power (MVAr). Newton-Raphson gives more accurate results because it performs more iteration as compare to Gauss-Seidel. In the case when demand increases at bus 2 set as almost double, as a result load on the transformer between bus 3 and bus 4 increases and also reactive power in generator at bus 3 increases which indicates that losses in the generator also increases. It is observed that the acceptable generated range at bus 2 is 844MW, demand increases but power at bus to not upto required demand. Figure 5.1 In PWS the shunt capacitor connected on bus 2 in parallel with load and this method of connecting capacitor in parallel with load is known as power factor correction and decreases the apparent power of source, so source current also decreases. As the line connected between the load and generator line losses decrease and less line voltage drop across the line. The capacitor of 210 Mvar rating inserted at bus 2 and decreases the losses from 46.50 MW to 29.1MW as shown in area field option dialogue below: The connected capacitor shown in figure 5.2 which supplying the reactive power of 188.1Mvar. Capacitive reactance rating depends on assumed voltage 1.0 pu and this loss due to capacitor reactance varies directly with the square of the voltage. The voltage at bus 2 increases to 0.95 pu as per requirement also shown in figure 5.2 Figure 5.2 After that another possible changing in five-bus power system performed to find the low voltage problem, for that another transmission line inserted in parallel between bus 4 and 2 having the same parameters with the already exciting model and then simulation performed. After that all the parameters analyse and at bus 3 MVar of the generator decreases and hence losses. Load on line between bus 3 and 4 also decreases. At bus 2 the voltage increases to 0.96 pu and losses at bus 2 decreases shown area field dialogue given below. By inserting transmission line power factor also improve and simulated one-line diagram shown in the figure 5.3. The choice for inserting the line is less preferable as compare to capacitor in real implementation because of the cost factor but both these can be used for power factor improvement. Figure 5.3 In PWS, the real and reactive mismatches equation by simply selecting the option mismatches option, the table given below shows real and reactive power mismatches. The convergence tolerance is  ±1% of their rated value. The transmission line between bus 2 and 4 is removed for maintenance. After that five bus power system again simulated and its operating condition is not acceptable because transmission line between bus 5 and bus 4 is overloaded. Then in order to run the system under normal condition the load at bus 2 and bus 3 are equally shared in such a way that the overloading on the transmission line between bus 5 and bus 4 is reduced. 6. Conclusion After completing this project, we get enough information about how to draw bus power system by using Power World Simulator (PWS). This simulation software easy to use and give brief description of each step, voltage, load angle etc. Most importantly this software is less time consuming and free from any human error. This project gives very good understanding and knowledge about bus power system and clear idea about the different parameters that mainly analysed during simulation. Now a days mostly all industries using such kind of softwares in order to check any fault and transmission losses. Mainly electric consumption have increased and also the number of interconnections, so future planning become more complex. The software like PWS efficiently calculates power-flow solution of any numbers of bus power systems. This project gives an idea to analyse different kind of transmission design.

Earning a Patch for Weightloss :: Dieting Health Essays

Earning a Patch for Weightloss While surfing the net in search of weight loss aids, one may soon come to the dermalife homepage. Here, along with various products for acne, bust firmness, and fat burning, the web site introduces the "NEW Derma Lifepatch" for losing weight. The active ingredient in this patch is taken from a brown alga called fucus vesiculosus or bladder wrack. The main ingredient used from fucus vesiculosus is iodine which stimulates the thyroid gland to speed up metabolism. In this essay, I would like to examine the value of this substance in terms of weight loss as well as possible health risks that may be associated with it. Much of the information contained herein is taken form studies on fucus vesiculosus and the thyroid gland and not on the Derma Patch specifically. A Little Background on Metabolism: "Human energy expenditure can be understood by a division into three components: basal or resting metabolic rate (RMR), the thermic effect of food (TEF), and the thermic effect of activity (TEA). The stoichiometric relationships between oxygen consumption and the heat release that occurs with biologic substrate oxidations are similar to those seen in chemical combustion. As a result, the rate of energy expenditure and substrate oxidation can be determined by measuring heat losses (direct calorimetry) or by measuring oxygen consumption and carbon dioxide production." RMR defines that energy which is needed for the basic maintenance of the body. The TEF is defined as the elevation of metabolic rate occurring after food ingestion. It includes the cost of the absorption, metabolism, and storage of the food within the body. The TEA is the energy expended with activity and exercise. When most people speak of raising their metabolism (as in trying to lose weight) and throughout the r emainder of this essay, we are mostly speaking of increasing the activity of TEA (Pi-Sunyer, 1). Thyroid Manipulation and Weight Loss: The thyroid gland plays an important role in regulating the body's metabolism (Thyroid Fed. Int'l, 1998). The body's metabolic rate is directly linked to the amount of activity of the thyroid. If the thyroid gland hormone is enhanced by medication, the obvious result is that metabolism is increased. Thus, the body is able to burn more calories quicker and less are deposited as fat.

Sarva Shiksha Abhiyan is a quantitative success: IIM study There are some good tidings for the Union Human Resource Development Ministry from its flagship enterprise, the Sarva Shiksha Abhiyan (SSA), to universalise elementary education. A study conducted by the Indian Institute of Management, Ahmedabad (IIM-A), has found that the SSA has met with considerable success quantitatively if not qualitatively.While quality remains an area of concern, the SSA has been able to bridge the enrolment, retention and achievement gaps between the sexes and among social groups. According to the IIM-A study titled `Shiksha Sangam: Innovations under the SSA,' the out-of-school population had come down from 28. 5 per cent of the six-to-14 year age group in 2001 to 6. 94 per cent by the end of 2005. Dropout rates at the primary level stands at about 12 per cent and 190 of the 400 districts were showing a declining trend in 2005-2006.The SSA has been able to bring Scheduled Castes and Scheduled Tribes ( SC/STs) — weak points in earlier efforts to universalise elementary education — into the educational mainstream. Greater share The share of SC/ST children at the primary level in 2004-2005 was actually greater than their respective proportion of the population: 20. 73 per cent in the case of SCs against a population share of 16. 2 per cent and 10. 69 per cent against a population share of 8. per cent. The gender gap in enrolment now stands at 4. 2 percentage points at the primary level and 8. 8 percentage points at the upper primary level. In 2005-2006, there were only 22 districts (of the 400 for which data was available) where the gender gap was more than 10 percentage points at the primary level. However, the success rate on this count in the upper primary level is not so good as 82 districts have reported a gap of more than 15 percentage points.
