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...

This study examined the patterns of mobile phone usage and preference of mobile phone functions amongst elderly people in Hong Kong. Two studies were conducted using a mixed-research method. Focus group discussion was conducted to six elderly mobile phone users to investigate their usage patterns and problems of using. Questionnaire survey was administrated to 100 respondents aged 60 and over t...

This paper argues that there are two types of mobile phone user. The study focused on the interactional experience of mobile phone calls and text messages. The research involved 32 UK mobile phone users and included extended interviews, 24-hour communication diaries, mobile phone bills and an analysis of text messages. The sample was evenly divided between men and women, and between two age ban...

In this research, we propose an architectural solution to implement the voice over IP (VoIP) service in campus environment network. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to analyze the VoIP Codec se...

In the present work we address the problem of phone duration modeling for the needs of emotional speech synthesis. Specifically, relying on ten well known machine learning techniques, we investigate the practical usefulness of two feature selection techniques, namely the Relief and the Correlation-based Feature Selection (CFS) algorithms, for improving the accuracy of phone duration modeling. T...

Abstract Introduction: Mobile phones create high-frequency electromagnetic fields around them when in use. The close proximity of mobile phones to the user’s head leads to the absorption of part of the electromagnetic waves into the head and the brain. Methods: We have elucidated the alteration in cognitive function of the male and female offspring rats, which were exposed to chronic mobi...
