An old saying coming from the telecom world states that nothing can be really considered as a service unless you are able to charge for it. As we move towards a service-oriented society, the necessity to pay in real time for a variety of services via different channels anywhere, anytime, in any currency increases. According to Gartner (www.gartner. com), worldwide mobile phone sales totaled 816...

In this study, we propose an innovative approach using the “Contextual Mobile Learning System” based on the “Electronic Performance Support System” (EPSS) to support efficient just-in-time learning for professionals working in the “Smart city”. In this paper, we present the principle and the structure of our contextual mobile learning system, which uses a search engine to find appropriate learn...

Asdata from mobile coronary units and coronary care units in the early 1970s accumulated, we saw a strong association between the incidence of premature ventricular contractions (PVCs) and sudden coronary death.1 The profession devised and delivered treatment in a climate charged with the fear that PVCs would inevitably trigger ventricular fibrillation. The picture was a familiar one in CCUs: p...

The convergence of multiple technologies has given rise to new types of information utilities called mobile location-based services. Specifically, the authors examine a context in which people need to move physically from one location to another via taxis. In this scenario, the user is in control of the location information associated with the mobile device. However, problems arise when a fleet...

Today it is common that upper end mobile telephones (smartphones) include maps and navigation systems. New hardware technologies for presenting maps require development in cartography. To define rules and methods for cartography on such small displays it is useful to study how people comprehend the maps on their mobile units. This paper discusses how mobile phones can be used as means for carto...

The emergence of ubiquitous computing offers new possibilities and opportunities for organizations attempting to improve their productivity and effectiveness. In particular, the promises of ubiquitous computing are attractive to organizations such as transport firms, in which coordination of diverse sets of mobile units is central to organizational performance. This article analyzes the use of ...

In recent years there has been an explosion of interest in wide-area distributed applications, executing on intranets or on the global internet [CHK97]. A key concept for structuring such applications is that of mobile agents, i.e. units of executing code that can migrate between sites. Mobile agents require novel programming language support and raise new problems, of interaction between agent...

Mobile communications demands present new challenges for transmission. Traditionally, antennas used at base stations to communicate with mobile units within an area are omni-directional. In order to allow a higher density of participants within the area, a “pencil” beam is used. The beam tracks and follows the movement of the mobile unit. This results in an additional advantage: the fading effe...

Discussions about mobile applications and businesses often deal with technical issues on distribution and representation. Content, when discussed, is typically considered as a set of measurable units, like size, form and version, and left with that. This paper stresses the importance of also regarding content as the result of a creative process. A content theory is presented and used as a backd...
