Dear Editor,Lack of ionizing radiation and the low level energy emission from cell phones initially led to a public perception that use of mobile phones is safe. However, the dramatic increase in the use of cell phones has generated great concerns about their potential adverse effects. We have previously found no association between self-reported illness symptoms and the exposures to microwave ...

An overview of research activity in the area of powering base station sites by means of renewable energy sources is given. It is shown that mobile network operators express significant interest for powering remote base stations using renewable energy sources. This is because a significant percentage of remote base station sites on the global level are still diesel powered due to lack of connect...

Mobile phones adoption and diffusion is a practical issue that has significant implications for e-commerce and m-commerce development. Examining the adoption of mobile phones from the well-developed theoretical foundation of innovation diffusion theory may clarify some significant factors that affect the adoption decision. Moreover, with the understanding of the influence sources of mobile phon...

We investigate the reachability problem for fragments of the Mobile Ambients, a powerful model for distributed and mobile computation. By using a connection with associative-commutative term rewriting, we prove that reachability is decidable in the open-free fragment of pure Mobile Ambients with name restriction and weak reduction semantics. Processes in this model have three sources of infinit...

BACKGROUND Nowadays, mothers are continuously exposed to different sources of electromagnetic fields before and even during pregnancy.  It has recently been shown that exposure to mobile phone radiation during pregnancy may lead to adverse effects on the brain development in offspring and cause hyperactivity. Researchers have shown that behavioral problems in laboratory animals which have a sim...

The chapter investigates different sources of trust as factors affecting consumers’ willingness to provide companies with personal information and the permission to use it in mobile marketing. The chapter develops a conceptual model, which is tested with data from a survey of 200 young Finnish consumers. The data were analyzed by means of structural equation modeling (LISREL8.7). The main sourc...

In this position paper we discuss information systems access in a mobile context-dependent user environment, characterized by multiple information sources, in particular w.r.t. the relationships between context and multiple sources.

Mobile differential optical absorption spectroscopy (mobile DOAS) is an optical remote sensing method that can rapidly measure trace gas emission flux from air pollution sources (such as power plants, industrial areas, and cities) in real time. Generally, mobile DOAS is influenced by wind, drive velocity, and other factors, especially in the usage of wind field when the emission flux in a mobil...

Creating a global information-sharing environment in the presence of autonomy and heterogeneity of data sources is a difficult task. When adding mobility and wireless medium to this mix, the constraints on bandwidth, connectivity, and resources worsen the problem. Our past research in global information sharing systems resulted in the design, implementation, and prototype of a search engine, th...

Due to advancements in mobile technology and connectivity, mobile devices have become fully-fledged web clients. At the same time, more and more Semantic Web data is becoming available, to a point where it becomes usable for various mobile application scenarios. However, most applications are limited to using pre-defined query endpoints in order to access Semantic Web data, which leaves a huge ...
