ISSUES The rapid rise of mobile phone use in poor countries is well known as an exemplary case of a technology enabling bottom-up empowerment through information access, driven by smallmargin business and end-user innovation. While many are not mobile phone owners themselves, few today face a several mile walk to access an often-disconnected landline phone for communication, which was a regular...

Background Mobile phone has played an increasingly important role in people’s lives; however, there is a global concern that it may cause adverse effects on health. This study aimed to assess the effect of educational intervention based on Health Belief Model (HBM) to d...

introduction: there are general concerns about the hazardous impacts of the cell phones radiation on the human health. in this study, the structural and biochemical changes of the mice kidney were assessed after cell phone exposure in. materials and methods: a total of 40 balb/c mice were randomly divided into the control and experimental groups. the experimental group exposed to cell phone dev...

Objective(s): The increasing rate of over using cell phones has been considerable in youths and pregnant women. We examined the effect of mobile phones radiation on genes expression variation on cerebellum of BALB/c mice before and after of the birth. Materials and Methods: In this study, amobile phone jammer, which is an instrument to prevent receiving signals between cellular phonesand base t...

Introduction: Over the last decade, exposure to electromagnetic waves due to base station antennas has increased. This study was planned to evaluate the effects of different electrical field strengths with 950 MHz waves of the GSM mobile phone system on the excitatory postsynaptic potentiation (EPSP) slope of the dentate gyrus long-term potentiation (LTP). Material and Methods: Twenty four naiv...

Introduction: Over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. This in vivo study was planned for evaluating the effects of whole-body exposure to 950 MHz field of GSM mobile phone system on rat dentate gyrus long-term potentiation. Materials and Methods: 24 naive male Wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

Rate-Distortion-Complexity Optimization of Video Encoders with Applications to Sign Language Video Compression Rahul Vanam Co-Chairs of the Supervisory Committee: Professor Eve A. Riskin Electrical Engineering Professor Richard E. Ladner Computer Science and Engineering Applications for video compression have been growing over the years due to the availability of higher network bandwidth, lower...

BACKGROUND HIV infection is clinically managed with antiretroviral therapy (ART), but only with sustained adherence. Cost-efficient interventions to improve and sustain ART adherence remain a pressing priority for populations challenged by nonadherence. The aim of this study was to test the independent and interactive effects of (1) brief phone-delivered self-regulation counseling and (2) daily...

Speech attributes, such as places and manners of articulation are robust against cross-speaker variation and environmental distortions. They have been used in various speech processing applications such as spoken language identification, speaker recognition and speech recognition. In this paper, we propose a method to recognize speech attributes by using a context-dependent modeling of the attr...
