In this paper we propose a passenger bus navigation system using Wireless Sensor Network (WSNs). This System comprises of three Units: Bus Station Unit, Bus Unit and Blind Unit. The Blind people on the Bus Station are provided with a Blind Unit. The blind speaks his destination on the microphone provided on the Bus Station Unit. When the desired bus stops at the station for the Blind, then via ...

INTRODUCTION Recent legislation requires schools to provide free drinking water in food service areas (FSAs). Our objective was to describe access to water at baseline and student water intake in school FSAs and to examine barriers to and strategies for implementation of drinking water requirements. METHODS We randomly sampled 24 California Bay Area public schools. We interviewed 1 administra...

Over the past decade, rateless codes, i.e., digital fountain codes, have emerged as an efficient and robust solution for reliable data transmission over packet erasure networks and a particularly suitable one for multicasting and broadcasting applications where users may experience variable channel conditions and packet loss rates, such as mobile environments. Luby Transform (LT) and Raptor cod...

One of the most poorly understood stellar evolutionary paths is that binary systems undergoing common-envelope evolution, when envelope a giant star engulfs orbit companion. The interaction ensues leads to great variety astrophysical and associated phenomena, but happens over very short timescale. Unfortunately, direct empirical studies this momentous complex phase are difficult at present beca...

Little is known about large sulfur bacteria (LSB) that inhabit sulfidic groundwater seeps in large lakes. To examine how geochemically relevant microbial metabolisms are partitioned among community members, we conducted metagenomic analysis of a chemosynthetic microbial mat in the Isolated Sinkhole, which is in a deep, aphotic environment of Lake Huron. For comparison, we also analyzed a white ...

The Holy Shrine of Imam RezaAS is one of the most important places in Iran in terms of religious and public beliefs. Huge volumes of pilgrims travel to the mentioned place, so the appropriated environmental and furniture design to increase the visitors' satisfaction is inevitable. In this regards, the main objective of this study is to identify an appropriated design for public water taps throu...

Gas that escapes from the Galactic disk, rises into the halo, cools and falls back, constitutes a “Galactic fountain”. Three-dimensional simulations show that such a fountain model reproduces many of the features that have been observed in the Galaxy and other galaxies such as M31 and M33. Here, these results are reported.
