Query processing in global information systems integrating multiple heterogeneous sources is a challenging issue in relation to the effective extraction of information available on-line. In this paper we propose intelligent, tool-supported techniques for querying global information systems integrating both structured and semistructured data sources. The techniques have been developed in the env...

The real time use of signal processing for brass instrument performance ~specifically the trombone! provides an opportunity, as well as challenges, to create a type of hyper-instrument quite unlike most conceptions of the term. These include the expansion of the available sound palette, the problem of real time parameter control, microphone techniques, and repertoire considerations. The various...

The strengths and weaknesses of agent-based approaches and classical optimization techniques are compared. Their appropriateness for resource allocation problems were resources are distributed and demand is changing is evaluated. We conclude that their properties are complementary and that it seems beneficial to combine the approaches. Some suggestions of such hybrid systems are sketched and tw...

Graphic and diagrammatic techniques have always been very popular for defining and communicating software system properties. Engineering in general has a whole body of drawing techniques to design complex systems. In software engineering research and practice tried to emulate these drawing techniques and early approaches like ER and SA diagrams1) are still in use today. Recently object orientat...

Process modeling has become an essential aspect of information systems (IS) practice. In line with the increased popularity, a plethora of process modeling techniques has been proposed over time. Yet, despite the proliferation of techniques, only a few have been widely accepted by practitioner communities. However, the long-term viability of a process modeling technique and its eventual success...

The LITCHI project is concerned with the integration and maintenance of databases of biological knowledge organised by species. We use constraints pertaining to good taxonomic practice in order to identify taxonomic conflicts in individual species databases and in databases formed by merging species databases from distinct sources. The LITCHI system can be used to resolve such conflicts increme...

When a manufacturing process is subject to random shocks, detecting the changes in the process and adjusting an out-of-target process are two essential functions of process quality control. Traditional SPC techniques emphasize process change detection, but do not provide an explicit process adjustment method. This paper discusses a general sequential adjustment procedure based on Stochastic App...

In external beam radiotherapy, modern technologies for dynamic dose delivery and beam conformation provide high selectivity in radiation dose administration to the pathological volume. A comparable accuracy level is needed in the 3-D localization of tumor and organs at risk (OARs), in order to accomplish the planned dose distribution in the reality of each irradiation session. In-room imaging t...
