The worldwide introduction of third generation mobile phone networks, coupled with advanced handsets capable of hosting rich client applications, provides a new context for mass access information systems. This infrastructure provides the opportunity to move on from the client-server and intranet models of mobile computing and build more sophisticated mass-client architectures that distribute p...

In this paper, we introduce an architecture for a new generation of speech applications. The presented architecture is based on our previous work with multilingual speech applications and extends it by introducing support for synchronized distributed dialogues, which is needed in emerging application areas, such as mobile and ubiquitous computing. The architecture supports coordinated distribut...

This paper presents a practical approach to parallelize the test data generation algorithm by which computing resources can be fully used. The test data generation approach that we are using is based on the dynamic symbolic execution (concolic testing). The basic idea of parallelizing the algorithm is to distribute analysis processes of different paths to different computing units. Although a c...

Luleå University of Technology has for the last few years deployed a netbased learning environment, mStar, to distribute courses to students independent of time and geographic distance. The mStar enviroment gives remotely attending students equal possibilities as traditionally attending students to take an active part of a course, as well as enhancing the learning experience for all students. T...

The fifth generation (5G) mobile telecommunication network is expected to support multi-access mobile edge computing (MEC), which intends to distribute computation tasks and services from the central cloud to the edge clouds. Towards ultraresponsive, ultra-reliable and ultra-low-latency MEC services, the current mobile network security architecture should enable more decentralized approach for ...
