Virtual University And Globalisation

Globalization as an inevitable process in the twenty-first century in economic, political and cultural dimensions creates changes in education and higher education. Virtual universities have important role in globalization. It is clear that globalization in higher education can affect on other area same economic, culture and etc. Virtual university with special programs and use of information and communication technology (ICT) can show the impact of globalization on society, the economy, and the world system. At virtual universities there are international programs that extend globalization. Globalization requires the existence and development of an advanced information and communications infrastructure. And at virtual university that is new phenomenon in new age we can provide these infrastructures. Also, globalization requires a different education that enhances the ability of learners to access, assess, adopt, and apply knowledge, to think independently to exercise appropriate judgment and to collaborate with others to make sense of new situations. In this paper researcher want to show the impact of keys factors at virtual university on the globalization. Keywords: Virtual University, Globalization, Higher education

Interference and X Networks with Noisy Cooperation and Feedback

The Gaussian $K$-user interference and $M\times K$ X channels are investigated with no instantaneous channel state information (CSI) at transmitters. First, it is assumed that the CSI is fed back to all nodes after a finite delay (delayed CSIT), and furthermore, the transmitters operate in full-duplex mode, i.e., they can transmit and receive simultaneously. Achievable results are obtained on the degrees of freedom (DoF) of these channels under the above assumption. It is observed that, in contrast with no CSIT and full CSIT models, when CSIT is delayed, the achievable DoFs for both channels with full-duplex transmitter cooperation are greater than the best available achievable results on their DoF without transmitter cooperation. Our results are the first to show that the full-duplex transmitter cooperation can potentially improve the channel DoF with delayed CSIT. Then, $K$-user interference and $K\times K$ X channels are considered with output feedback, wherein the channel output of each receiver is causally fed back to its corresponding transmitter. Our achievable results with output feedback demonstrate strict DoF improvements over those with the full-duplex delayed CSIT when $K>5$ in the $K$-user interference channel and $K>2$ in the $K\times K$ X channel. Next, the combination of delayed CSIT and output feedback, known as Shannon feedback, is studied and strictly higher DoFs compared to the output feedback model are achieved in the $K$-user interference channel when K=5 or $K>6$, and in the $K\times K$ X channel when $K>2$. Although being strictly greater than 1 and increasing with size of the networks, the achievable DoFs in all the models studied in this paper approach limiting values not greater than 2.Comment: 53 pages, 15 figures; Submitted to IEEE Transactions on Information Theory, May 2012.

Muslims and Public Places: A Platform for Inclusion or Exclusion?

This thesis investigates the experiences of first-generation and second-generation Muslim immigrants in Knoxville, Tennessee. It is based on fieldwork, participant observation, and interviews conducted from August 2017 to June 2018. The interviews were conducted with fifteen individuals, eleven women and four men who were recruited through Muslim Centers in Knoxville and the University of Tennessee campus. I argue that social pressure and the negative climate affects the way Muslims are treated in the United States in public places. Muslim immigrants in Knoxville had positive and negative experiences of being in public places. They use public places for religious holidays and festivals organized by the Muslim Community of Knoxville, small-scale events organized by several Muslim organizations, and general leisure activities. Positive experiences of using public places include socializing with others within the community, involvement in city life, and assertion of their Muslim identity as part of Knoxville. Reported negative experiences ranged from stares to verbal attacks in public. My findings showed that Muslim women wearing hijab are more at risk of having negative experiences, compared to Muslim men or Muslim women who do not wear hijab. Responses to discrimination included ignoring stares and comments, responding to them, taking extra precautions, and avoiding certain public places. However, for most of the Muslim immigrants interviewed, the negative experiences did not cause them to avoid using public places. In particular, Muslim immigrants in Knoxville prefer to spend their leisure time engaging in group activities with friends, family, and other members of their various immigrant communities using urban green spaces that are not crowded and that provide picnic areas and grassy areas for group sports

A spatial analysis of supply-demand of public transportation in Jefferson County, Kentucky.

Public transportation is important as it serves individuals, especially the transit-dependent population, by providing a basic mobility service to these people and all others who rely on public transportation. This research utilized estimating public transportation demand and supply to analyze the spatial patterns of public transportation in Jefferson County, Kentucky. The study focuses on the transit-dependent population, and it considers indicators of age, poverty status, vehicle ownership, and foreign-born population with less than five years residency in the United States. This study conducted a public transit supply-demand analysis to identify areas with imbalanced supply and demand in Jefferson County at the Traffic Analysis Zone

Design and Fabrication of Polyvinylidene Fluoride for Triboelectric Nanogenerators

Recently triboelectric nanogenerators (TENGs) have attracted huge interest because of their flexibility to harvest wasted mechanical energy. However, triboelectrification is a well-known phenomenon for centuries, the underlying physics behind it is still under debate, so a comprehensive study on triboelectrification is needed. Herein, effects of polyvinylidene fluoride (PVDF) friction layers thickness, contact area and porosity on TENGs performance were investigated. Results showed that increasing surface area or decreasing thickness of friction layer positively affected the performance of TENG. This is mainly attributed to improvement of PVDF charge density. Then, for further enhancement of TENGs performance, electroactive phase content of PVDF enhanced using different fabrication methods such as supercritical CO2 processing, non-isothermal crystallization, electro-poling and electrospinning. The results confirmed increasing in PVDF electroactive phase content positively affected triboelectric properties. Consequently, by fabrication of chitin-PVDF electrospun film the average of voltage and current density increased to 72.8 V and 6.47 mA/m2, respectively
