The global electrical energy consumption is rising and there is a steady increase of the demand on the power capacity, efficient production, distribution and utilization of energy. Power electronics, the technology of efficiently processing electric power, play an essential part in the integration of the dispersed generating stations for higher efficiency and better performance of the power systems. This project deals with the simulation of grid connected inverter for Photovoltaic applications. Space vector pulse width modulation (SVPWM) technique has been adopted for generating pulses for the two level inverter. The entire system comprising of Photovoltaic array (PVA) and two level inverter has been developed in Mat lab-Simulink. The PVA model characteristics including the effects of temperature and solar irradiation change on maximum power point are also presented in this paper. The inverter output has been synchronized with the grid using d-q theory and the power flow is controlled at 200kw. Finally, the inverter has been tested in grid connected mode.

The key factor in video processing is the Video Compression (VC) which makes video signal to be processed and stored efficiently. Video compression involves complex algorithms such as Motion Estimation (ME). The hardware implementation of motion estimation has a trade-off between area, speed and Power Dissipation (PD). This paper implements high speed low complexity Variable Block Size Motion Estimation (VBSME) for H.264 standard using verilog coding on Altera Stratix – IV Field Programmable Gate Array (FPGA) (EP4SGX70DF29C2X) device, using parallel and pipeline timing approach to achieve high speed and the low complexity for High Definition Television (HDTV) system. The proposed work computes all 41 vectors of various block sizes during 180 clock cycles with less complexity using only 46 Processing unit Elements (PEs) and achieves a maximum operating frequency of 486.62 MHz.

In the present study, the defatted successive ethyl acetate and methanol extracts from Trapa natans fruit peel were evaluated for their protective effects on paracetamol-induced liver damage in Wistar albino rats. Serum biochemical parameters viz. serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (SALP), total protein, bilirubin, cholesterol, triglycerides were evaluated. All biochemical findings indicated that both the test extracts exerted significant hepatoprotective efficacy against paracetamol-induced hepatic damage in rats. The methanol extract was found to be more effective than the ethyl acetate extract. Therefore, from the present study it can be concluded that T. natans fruit peel had remarkable hepatoprotective activity in rats.

What should we do when the customer service is poor or when we buy a faulty product but the store does not let us return it? We should resolve such problems through complaining effectively. Having a good command of grammatical rules and vocabulary of the language is necessary but it is not enough; the ability to produce language that is socially and culturally appropriate is a real asset in settling such problems. This study attempted to compare the pragmatic competence of Iranian EFL learners with that of native speakers of English language when they find it necessary to perform the speech act of complaint. Ten Iranian EFL students of Azad University in Lahijan served as the subjects of this study. The data were collected through comparing the complaint letters written by American native speakers with those by Iranian EFL learners. The responses were analyzed in terms of the main components of complaints. The findings indicated that American native speakers and Iranian EFL learners showed different pragmatic behaviors.

Analytical solution of advection-dispersion equation (ADE) is obtained for one-dimensional semi-infinite porous medium with periodic input boundary and periodic flow velocity. The dispersion coefficient is directly proportional to flow velocity. Laplace Transformation Technique is employing to get the analytical solution with exponentially increasing function of space variable initial condition and periodic input boundary condition. Analytical solution is illustrated graphically.

This study examined the household willingness to pay for improve improved solid waste disposal in Ibadan metropolis of Oyo state, Nigeria. . Data were collected randomly from one hundred and fifty-two (152) respondents with the use of structured questionnaire. Data analysis revealed that 53.3% of the respondents were male while 77% were married. Average household size was 5.87 members while average age was 41.8 years. More than half of the respondents are willing to pay for improved solid waste disposal. Logit analysis revealed that age, marital status, education, total household expenditure, price and bids has effect on willingness to pay for improved solid waste disposal at different level of significance. Tobit analysis showed that household expenditure, price of waste disposal and education have negative coefficient, number of sacks generated, marital status and house ownership has positive effect on the mean amount respondents were willing to pay for improved solid waste disposal.

Ethics are important because finances make people do some strange things. The spreadsheet does not have a conscience, and the goal of working with spreadsheets is to make numbers add up in a way that is pleasing to the organizations and its constituents. Ethical behavior is an important aspect for the success of a company, as it influences its relations with various stakeholders. Financial managers are responsible for the difficulty in interpreting sensitive and Exchanges presenting them in the form of financial reports that can be used to evaluate corporate performance is Month interest groups are responsible. So unethical professional practice includes providing financial information poor quality can destroy public confidence in financial management. With increasing global attention to the topic of ethics and quality of information in the accounting profession, in this paper an attempt has been made to the research vacuum in the corner of the financial manager explained the moral perspective on the quality of financial reporting to be filled. Field research companies in Tehran Stock Exchange are accepted. In this study, the ethical perspective of financial management as the independent variable is the moral status was assessed with a questionnaire. Quality and usefulness of financial reporting used to be correct financial reporting as dependent variables were examined. The aims of the present study include applied research, in terms of how to collect the required data from the standpoint of descriptive and correlation research is considered. For data analysis software (SPSS) was used. Based on the results obtained from the ethical perspective of financial management and financial reporting, there is a significant relationship; It is recommended that companies choose their money managers not only scientific and practical aspects of management should be considered But the ethical aspect of the study is important for managers should pay special attention to ethics and corporate managers have a choice.

Quality of work focuses on the quality of relationship between employees and the total working environment. The fundamental rationale is to develop work environment that are splendid for people as well for the economic health of the organization. Quality at work trims down attrition intentions of the prospective employees and then helps out in reducing absenteeism and improving job satisfaction. Hence organizations today do customary in providing quality at work in order to keep hold of the talented workforce thereby enhancing their competitiveness. However in the current scenario the Indian IT sector is experiencing considerably high-level of staff attrition contrast to other sectors. Therefore this research was conducted among the software professionals to know their perception towards the quality of work life provided to them in their society.
