Today software is the main enabler of many of the appliances and devices omnipresent in our daily life and important for our well being and work satisfaction. It is expected that the software works as intended, and that the software always and everywhere provides us with the best possible utility. This paper discusses the motivation, technical approach, and innovative results of the MUSIC proje...

Processing data streams with Quality-ofService (QoS) guarantees is an emerging area in existing streaming applications. Although it is possible to negotiate the result quality and to reserve the required processing resources in advance, it remains a challenge to adapt the DSMS to data stream characteristics which are not known in advance or are difficult to obtain. Within this paper we present ...

The aim of this paper is to introduce a novel approach to determining how the decision – making behaviour of a military system could be influenced by the cultural attributes demonstrated by the system both as a whole and by its sub-systems. The research will also address how well a system with a particular configuration of cultural attributes will function in a designated operating environment....

Network monitoring is a vital part of modern network infrastructure management. Existing techniques either present a restricted view of network behavior and state, or do not efficiently scale to higher network speeds and heavier monitoring workloads. We present a novel architecture for programmable packet-level network monitoring that addresses these shortcomings. Our approach allows users to c...

Workstation clusters are being recognized as the main promising computing resource of the near future. A large size workstation cluster, consisting of locally connected workstations, has the power comparable to a supercomputer, at a fraction of the cost. Further, a wide area coupling of workstation clusters is not only suitable for exchange of mail and news or establishment of distributed infor...

In this paper, we discuss the major issues associated with the new model of software delivery – service on demand – and explain why it alters the economics of software. As this model is expected to deliver fundamental leaps in cost efficiency, operation performance, infrastructure orchestration and application control, we describe the supporting technology required to achieve these goals. We al...

Civilian applications for UAVs will bring these vehicles into low flying areas cluttered with obstacles such as building, trees, power lines, and more importantly civilians. The high accident rate of UAVs means that civilian use will come at a huge risk unless we design systems and protocols that can prevent UAV accidents, better train operators and augment pilot performance. This paper present...

The educational community’s demands for e-learning resources are analyzed in the paper. The intentions to individualize the learning material by modelling, developing and renewing the existing e-learning resources are emphasized. A successfully operating environment of e-material collaborative development, designed for knowledge community users with different competences, is examined. Various m...

In most jurisdictions, the rule of law has been the core instrument used to implement rules, regulations and restrictions relating to forests. The results of this approach have relied on the effectiveness of the system for regulating through monitoring and reporting. Despite the obvious differences in the wider operating environment of forestry internationally, issues related to globalization h...

The Inference Problem compromises database systems which are usually considered to be secure. Here, users pose sets of queries and infer unauthorized information from the responses that they obtain. An Inference Controller is a device that prevents and/or detects security violations via inference. We are particularly interested in the inference problem which occurs in a multilevel operating env...
