Background: The radiation emitted from electromagnetic fields (EMF) can cause biological effects on prokaryotic and eukaryotic cells, including non-thermal effects. Objective: The present study evaluated the non-thermal effects of wireless fidelity (Wi-Fi) operating at 2.4 GHz part of non-ionizing EMF on different pathogenic bacterial strains (Escherichia coli 0157H7, Staphylococcus aureu...

Super Wi-Fi is a Wi-Fi-like network built upon TV white spaces (TVWS) exploiting cognitive radio (CR) techniques. Super Wi-Fi is expected to achieve larger coverage than today’s Wi-Fi thanks to its superior propagation characteristics, while suffering from smaller bandwidth compared to Wi-Fi (6–8 MHz versus 20 MHz) which limits its network capacity. Therefore, it has been a common belief that S...

While Wi-Fi 5 is still sufficient for many organizations and businesses, it important to consider upgrade 6. This article discusses the main differences between The goal identify key metrics transmission of information content signals, a method determining best use signals certain categories use, an analysis study influence frequencies on quality transmitted information, also analyzes growth ra...

male infertility is a distressingly common condition affecting about 1 in 20 of the male population. in a majority of the cases, the male partner produces sufficient numbers of spermatozoa to achieve fertilization but there are functional defects in these cells that prevent conception from occurring. in this study, the effects of wi-fi radiation on spermatogenesis, testes and testosterone of la...

In this paper we describe our configurable hotspot framework for ubiquitous interaction. A camera points to a physical space, the user defines interaction areas, and designs gestures by combining hotspots (rectangles) that detect simple 2D motions (left_right, top_bottom, etc.).

Computed tomography (CT)/magnetic resonance imaging (MRI) fusion is considered to be the best method for postimplant dosimetry of permanent prostate brachytherapy; however, it is inconvenient and costly. In T2*-weighted image (T2*-WI), seeds can be easily detected without the use of an intravenous contrast material. We present a novel method for postimplant dosimetry using T2*-WI/T2-weighted im...
