The issue of Coverage in visual sensor networks (VSNs) has attracted considerable attention due to sensors directional sensing characteristic. It answers the question that how well the target field is monitored by a network of sensors with video/image capturing capability. In floorplan scenario the network is to monitor a plane parallel to the sensors' deployment plane. For large scale applications...

Exposure to heavy metals has been associated to a higher incidence of multiple sclerosis. In this work, we present a possible relationship between serum mercury levels and development of multiple sclerosis in Isfahan, the third largest city in Iran. Seventy-four patients affected by multiple sclerosis were retrieved from multiple sclerosis (MS) clinic in Isfahan, Iran. By matching sex and age, 74...
OBJECTIVE Zinc, an essential trace element and a component of many enzymes, is involved in the synthesis, storage and release of insulin. The aim of the present study was to assess the effect of zinc supplementation on insulin resistance and components of the metabolic syndrome in prepubertal obese children. DESIGN This triple-masked, randomized, placebo-controlled cross-over trial was conducted...
Image data hiding is the hiding of invisible patterns in an image without degrading its visual quality. This hidden pattern can be visualized by overlaying the original image with watermarked ones. Also it can be visualized using a simple XNOR operation. In this paper we propose a method called Dot Diffusion with Nonlinear Thresholding (DDNT) to embed hidden data in halftone images and its modification...
