Recognition of everyday physical activities is difficult due to the challenges of building informative, yet unobtrusive sensors. The most widely deployed and used mobile computing device today is the mobile phone, which presents an obvious candidate for recognizing activities. This paper explores how coarse-grained GSM data from mobile phones can be used to recognize high-level properties of us...

The widespread diffusion of mobile communication systems pushes research and development efforts towards the implementation of new services accessible through mobile terminals. This work has been carried out in the framework of the PALIO Project in the fifth Research Framework of the European Commission. It has been considered a tourist service where each user may access information directly th...

Dear Editor, Recently, a paper was published (Salama et al., 2008) describing the effects of electromagnetic fields from a mobile phone on testicular functions in New Zealand White (NZW) rabbits. We have a number of concerns; the two most important ones deal with the exposure conditions and the biological effects respectively. Exposure was carried out by a GSM mobile phone at 800 MHz in ‘standb...

INTRODUCTION With the tremendous increase in number of mobile phone users world wide, the possible risks of this technology have become a serious concern. OBJECTIVE We tested the effects of mobile phone exposure on spatial memory performance. MATERIALS AND METHODS Male Wistar rats (10-12 weeks old) were exposed to 50 missed calls/day for 4 weeks from a GSM (900/1800 MHz) mobile phone in vib...

introduction: the mobile phone is viewed as an important communication tool and has become an integral part of the iranian society and they are increasingly using the mobile phone rather than the fixed line telephone as a way to keep in touch with their family, friends, colleagues and business associates. today, mobile phones are equipped with other features that allow further communication and...

INTRODUCTION The interaction of mobile phone radio-frequency electromagnetic radiation (RF-EMR) with the brain is a serious concern of our society. OBJECTIVE We evaluated the effect of RF-EMR from mobile phones on passive avoidance behaviour and hippocampal morphology in rats. MATERIALS AND METHODS Healthy male albino Wistar rats were exposed to RF-EMR by giving 50 missed calls (within 1 ho...

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...

We describe the WebSIM, an approach that integrates GSM SIMs into the Internet. The underlying idea is to implement a Web Server inside a SIM, and to allow for transparent access to it from the Internet. The contribution of our approach is that a SIM, which is currently a security module (smartcard) fitted in a GSM mobile phone, becomes also a personal security server in the Internet. Like any ...
