Web caching and Web prefetching are two important techniques used to reduce the noticeable response time perceived by users. By integrating Web caching and Web prefetching, these two techniques can complement each other since the Web caching technique exploits the temporal locality, whereas Web prefetching technique utilizes the spatial locality of Web objects [30]. In this paper, we develop algorithm Pre-IPGDSF# by integrating Web caching and Web prefetching in Web servers. For caching, we use innovative algorithm Intelligent Predictive Greedy Dual Size Frequency#, IPGDSF#, which is an enhanced version of algorithm GDSF# developed by us [13, 14, 15, 16, 17]. For prefetching, we use a static prefetching method. Using three different Web server logs, we use trace driven analysis to evaluate the effects of different replacement policies on the performance of a Web server. We specifically compare policies like GDSF, GDSF#, and IPGDSF# with the proposed integrated policy Pre-IPGDSF#. Using trace-driven simulations and for various standard cost criteria (hit rate and byte hit rate), we show that our proposed integrated policy outperforms all other algorithms under consideration.

This paper investigates a 2-D discrete time predator - prey interaction model. The equilibrium points are obtained and stability of the equilibrium points is analyzed. The phase portraits are obtained for different sets of parameter values. Also a bifurcation diagram is presented. Numerical simulations are performed and they exhibit rich dynamics of the discrete model.

The paper aims at assessing cost of governance and revenue assurance mechanisms. The methodology adopted by the paper involves the use of quantitative data for 9 years, from 2002 to 2010, which was generated from the annual report and accounts of the Central Bank of Iran. The data generated for the study was analyzed using graphs and simple percentage analysis. The finding of the paper shows that Cost of governance at state level has greatly increased in Iran. Similarly, the trend of Extra-Budgetary Expenditure put to question the implementation of budgets at the States. The paper concludes that the task of reducing cost of governance for revenue assurance at states level does not rest on the executive, legislature and judiciary alone. It is task demanding the collective effort of all stakeholders. Finally, the paper recommends that there is the need to reduce recurrent expenditure to sustainable level through reducing waste, inefficiency, corruption and duplication in government, as well as, make capital spending more effective.

The study of mineral contents of fresh and dried tilapia fish (Oreochromis niloticus) from Mcaiver Market, Warri South Local Government Area of Delta State, Nigeria were determined. The tilapia fishes were shared into two parts: one part was used to determine the mineral content of the fresh fish and the other part was oven dried before the analysis of mineral contents of both fishes. The minerals detected were in the order Na>Ca>K>Mg>Zn>Fe. It was observed that dried tilapia fish was more nutritional than the fresh tilapia fish. Dry tilapia fish should be consumed rather than fresh tilapia fish for proper nourishments.

Till date polymeric membranes play a major role in Reverse Osmosis Desalination Industries. Many researchers have been concentrated in order to develop optimum polymeric membranes. The optimization is done in previous decades by controlling the membrane formation reactions and by use of catalysts and some additives but the emergence of Nano-technology in membrane could provide a better alternative for polymer based membranes. In this research a general review on different conventional membrane process that are currently employed are discussed and how Nano-structured membranes that can be employed which will enhance the Reverse osmosis desalination performance and but number of challenges remain with regard to their practical execution.

Analysis of earth dams Stability, and their arching phenomenon, is one of the most important issues in geotechnical engineering. Arching dam, you can use one or more methods are analyzed. The main factor of instability dams, gravity effect, but other factors can, intensify or provoke them to be effective. To understand the factors intensifying landslide, could contribute significantly to the experts, and the stability of the dam dirt, and prevent the arching. The purpose of this paper is to examine the phenomenon of arching in the bathroom tight barrier with finite element method, and compared with studies of dam instrumentation, numerical analysis by finite element software PLAXIS, has been made. Analysis, using behavioral models Mohr-Coulomb, is done. On the other hand, we can say that, numerical methods in the analytical methods is very rapid, reliable and accurate, and therefore these methods, able to perform parametric studies, the boundary conditions are complex. So in this study, AH stresses dam Tang-e Hamam, has been studied, and then perform parametric studies, it was concluded that increasing the angle of internal friction shell dam, the dam will lead to increased confidence. However, by changing the geometry of the dam core, core thickness miles to miles and increase confidence rises Dam. Also, the arching, the barrier height is variable, and strongly arching and the maximum arching, core thickness depends on the height of the dam.

This study is a first neuropsychological evaluation of cognitive Impairment generated by the job strain to the teleoperators in call centers in sub-Saharan Africa; Particularly in the Democratic Republic of Congo, city of kinshasa. This study established a statistically significant relationship between Exposure to psychosocial factors (high psychological demand and low decision latitude) and the appearance of job strain in teleoperators. It also showed a statistically significant relationship between job strain and the appearance of cognitive disorders in teleoperators. Lastly, the exposure duration at the call center of six months or more, was retained as necessary time to see the psychosocial factors negatively impacting the mental health of the call center teleoperators.

The paper evaluates the effectiveness of recent initiatives introduced by the Royal Thai Government proliferate Broadband services in Thailand. With globalization, the society is constantly changing resulting by information technology and Internet access to play an important role in communication, social, political, economic or even environmental. Because of the rapid-technological advancement, it causes that many countries moving up their focus on developing infrastructure to enhance the information technology and innovation. The data transmission not only text messages but also pictures such as VDO conference is important to make use of information technology is faster and more efficient. The perception is very convenient and fast and hence requires a good core broadband infrastructure. The role of Information and Communication Technology infrastructure (ICT infrastructure) enables leaders on governments’ decision based on the real time and reliable information. Of course, the government leaders in many countries realized that the quality and performance on ICT infrastructure would directly affect developing countries. In order to monitor the countries in the crisis situation, the stable and qualified network is required which the government called as S-M-A-R-T network. Under ICT2020 Policy Framework and Broadband Policy, Ministry of ICT accelerates connected S-M-A-R-T network to develop ICT infrastructure in Thailand recently. On another hand, Thailand economy is also important mechanism for strengthening competitiveness. The new business opportunities with many other countries have defined a policy and planning in developing Broadband seriously and continuously. In this paper, the study will identify the policies and plans of development and building broadband infrastructure of the leaders in the development of broadband top of the world, including Japan, South Korea, Singapore, The United States, Australia and Sweden, a country that have a clear policy and plan development. The projects initiated and measures taken by the Government of Thailand in the broadband sector have been studied. The information has been gathered by interacting with the executive officers of the National Broadcasting and Telecommunications Commission (NBTC), Ministry of Information Communication and Technology, Thailand, from interviewing the officers of government departments: Ministry of Education (MOE), Ministry of Public Health (MOH) and etc.

In the economics of Iran according to the mixture of the incomes of the country, tax can be considered as a kind of assured income. Whereas the important part of tax revenues in Iran depends directly and non-directly on oil revenues, this important matter has severely damaged the tax incomes against fluctuated oil revenues. Being lower 20 percent share of direct incomes to general budget can be assessed as an increased share of oil from the incomes of government. The results of this research present that the extent of the oil revenues of the country has negative effect on tax revenues during research ages. The result is that for revising the structure of country tax system, this matter should be considered in execution process and how to use of expertise people power and revision in this case must be done?in order that tax system be efficient in national economy.
