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...

Mobile information community develops quickly, as mobile telecommunication technology matches to the third generation. XML-based GIS becomes a global standard and the foundation. Recent developed Geography Markup Language (GML) allows integration of GIS location-based services, telematics, and intelligent transportation systems. In this paper, we propose a tourism information system for support...

ooms et al sets out some good general principles for a global social support system to improve fairer global competitiveness as a result of redistribution. this commentary sets out to summarize some of the conditions that would need to be satisfied for it to level up gradients in inequality through such a social support system, using the national basketball association (nba) example as a point ...

Unlike distributed transactions, mobile transactions do not originate and end at the same site. The implication of the movement of such transactions is that classical atomicity, concurrency and recovery solutions must be revisited to capture the movement behavior. As an effort in this direction, we define a model of mobile transactions by building on the concepts of split transactions and globa...

Recently many cases of missing children between ages 14 and 17 years are reported. Parents always worry about the possibility of kidnapping of their children. This paper proposes an Android based solution to aid parents to track their children in real time. Nowadays, most mobile phones are equipped with location services capabilities allowing us to get the device’s geographic position in real t...

because of the need to develop specific measurement scales for different services industries, this study aimed to empirically develop a reliable and valid model specifically for measuring mobile telecommunication service quality. a multidimensional measurement model (ms-qual) has been proposed based on an extensive literature review and then, to assess the model validity, convergent and discrim...
