The majority of the world’s computing power is no longer in supercomputer centers and institutional machine rooms. Instead, it is now distributed in the hundreds of millions of personal computers all over the world. In a few more years, other consumer devices like game consoles and television set-top boxes may comprise a large fraction of total computing power. This change is critical to scient...

background & aims of the study: disregarding the health and use of polluted equipment in barbers lead to microbial infection expansion, skin diseases and particularly hematic diseases including aids and hepatitis. hence, the aim of present study is determining the health condition of female barbers of kangavar city, iran, in order to improve the health level and public health. methods: in this ...

In this paper, we propose a Hadoop-based Distributed Video Transcoding System in a cloud computing environment that transcodes various video codec formats into the MPEG-4 video format. This system provides various types of video content to heterogeneous devices such as smart phones, personal computers, television, and pads. We design and implement the system using the MapReduce framework, which...

This study showed that an image data acquisition system connecting a high-speed camera or webcam to a notebook or personal computer (PC) can precisely capture most dominant modes of vibration signal, but may involve the non-physical modes induced by the insufficient frame rates. Using a simple model, frequencies of these modes are properly predicted and excluded. Two experimental designs, whic...

Speech recognition in quiet and in noise was evaluated for children with normal hearing, children with hearing loss, and adults with normal hearing. Performance was evaluated in a classroom environment without use of wireless radio frequency (RF) hearing assistance technology (HAT) and with two different types of classroom audio distribution (CAD) systems (a fi xed-gain multiple loudspeaker sys...

We examine the process and performance effects of two different forms of functional diversity in management teams – the predominant conceptualization in the literature (dominant function diversity) and a second conceptualization that has been generally overlooked (intra-personal functional diversity). In a sample of business unit management teams, dominant function diversity had a negative and ...

An analytic means to evaluate the error sensitivity of a personal audio system is proposed. The personal audio system, which focuses acoustic energy into a zone of interest using multiple loudspeakers, is subject to various errors when implemented. The performance of a personal audio system, defined as an energy ratio between the zone of interest and the rest, is inevitably influenced by errors...

Abstract Introduction: not following safety tips during mobile radiography can bring about risks for nurses in ICU wards. Objective: the study aimed to determine the status of personal protection against radiation and its associated factors in nurses working in ICU wards of health care-educational centers affiliated with Guilan University of Medical Sciences in Rasht, Iran. Materials and Met...
