This study provides a survey overview of the literatures with goal maximizing efficiency DC-AC power conversion from an engineering science perspective. With advent wide band gap semiconductors, published literature on realizing high converters has increased. Therefore, high-efficiency inverters was first conducted. We demonstrated importance measurement accuracy in measuring losses, and then p...

The Internet is increasingly considered a crucial information resource. However, how the Internet is adopted as an information source within a given society depends on factors such as the technical infrastructure of a given area and the local culture. This paper reports on an ongoing study of the information behavior of people in Uzbekistan, a culture that has traditionally relied on social net...

This article surveys recent technical research and achievements in the field of RFID (Radio Frequency IDentification). Article also helps entering and better understanding the world of RFID systems. RFID tags are small, wireless devices that help identify objects and people. Thanks to dropping cost, they are likely to proliferate into the billions in the next several years – and eventually into...

Objective: To develop and validate an instrument for measuring the acquisition of technical skills in conducting operations of increasing difficulty for use in General Surgery Residency (GSR) programs. Methods: we built a surgical skills assessment tool containing 11 operations in increasing levels of difficulty. For instrument validation we used the face validaity method. Through an electronic...

Recently, several strategies for transaction processing in partitioned distributed database systems with replicated data have been proposed. We survey these strategies in light of the competing goals of maintaining correctness and achieving high availability. Extensions and combinations are then discussed, and guidelines for the selection of a strategy for a particular application are presented...

Conducted October 9-27, 2013, the Commonwealth Fund Affordable Care Act Tracking Survey interviewed a nationally representative sample of adults who are potentially eligible for the health reform law's new insurance coverage options, whether private plans or expanded Medicaid. Among the survey's key findings: 60 percent of potentially eligible adults are aware of the new marketplaces as a place...

In the last two years, mainly practitioners published newspapers and technical reports outlining the benefits and obstacles of Cloud Computing. Scientific research is limited to technical issues of Cloud Computing so far. Marketing and economic issues have been barely discussed in literature. Especially, customer considerations and pricing are only discussed vaguely in industry reports. A detai...
