In order to support multimedia applications in mobile environments, it will be necessary for applications to be aware of the underlying network conditions and also to be able to adapt their behaviour and that of the underlying platform. This paper focuses on the role of middleware in supporting such adaptation. In particular, we investigate the role of open implementation and reflection in the ...

In order to define a conceptual frame and a suitable vocabulary for this working area, we present the architecture description language MoDeL (Modular Design Language). By selecting and combining modelling concepts which proved to be helpful for the design of software systems, this approach is integrative and pragmatic: It unites different realization paradigms (structured, object-oriented), di...

Flight simulation has always been an application which needed to be distributed in order to be computable at all. Although examples of single-processor flight simulators exist [2] they are typically simulators of low fidelity, often games. True flight simulation has extremely high fidelity demands: the virtual environment which the simulator creates must be as life-like as possible in order to ...

This paper describes the functionality and software architecture of a generic problem-solving environment (PSE) for collaborative computational science and engineering. The PSE is designed to provide transparent access to heterogeneous distributed computing resources, and is intended to enhance research productivity by making it easier to construct, run, and analyze the results of computer simu...

The core problem of multi-agent distributed data mining technology not concern particular data mining techniques although the latter is now paid the most attention. Its core problem concerns collaborative work of distributed software in design of multi-agent system destined for distributed data mining and classification. The paper presents the developed and implemented distributed data mining t...

This paper focuses on the field of dynamically reconfigurable distributed embedded control systems construction process and presents a substantial part of the methodology aimed at this application area which is based on formal models, namely some variants of Petri Nets. Initial system specification is represented by a set of Workflow Petri Nets transformed into decomposed multi-layered Referenc...
