Software-based implementations of H.263 and MPEG2 video standards are well documented, recently reporting faster than or close to real-time performance. Since the complexity of MPEG-4 is higher than its predecessor standards, real time video encoding and decoding can exhaust computational resource without achieving real-time speed. In this paper, we report a software-based real-time MPEG-4 vide...

With the increasing complexity of modern construction projects, there is a pressing need on higher degree of assistance from computer in order to accomplish effective planning and management. This paper delineates the previous development and implementation of a prototype four-dimensional site management model (4DSMM), with the objectives to address the requirement for linking scheduling data t...

He has been teaching software processes at HUT since 1998 and his research interests include software processes and software engineering management. He is currently exploring how to manage software product development in SMEs. Casper Lassen...

Dem Projekt liegen zwei Konzepte zu Grunde, und zwar das Konzept eines webbasierten „Arbeitsplatzes im Netz“ und das der „Mitwachsenden Software“. Der „Arbeitsplatz im Netz“ erlaubt den Zugriff auf SO4K von allen Orten, die über einen Internetanschluss verfügen. „Mitwachsende Software“ bedeutet zum einen, dass die Funktionalität der Anwendung möglichst einfach an die Aufgabenstellung angepasst ...

This article presents a model for describing the architecture of software-intensive systems, based on the use of multiple, concurrent views. This use of multiple views allows to address separately the concerns of the various ‘stakeholders’ of the architecture: end-user, developers, systems engineers, project managers, etc., and to handle separately the functional and non functional requirements...

The term maintenance, when accompanied to software, assumes a meaning profoundly different from the meaning it assumes in any other engineering discipline. In fact, many engineering disciplines intend maintenance as the process of keeping something in working order, in repair. The key concept is the deterioration of an engineering artifact due to the use and the passing of time; the aim of main...

Software component reuse is the software engineering practice of developing new software products from existing components. A reuse library or component reuse repository organizes stores and manages reusable components. This paper describes how a reusable component is created, how it reuses the function and checking if optimized code is being used in building programs and applications. Finally ...
