We take the position that it could prove worth to reconcile ideas of the knowledge representation and software architecture research communities. Many existing knowledge representation techniques and formalisms seem to exhibit a lot of potential for representing different aspects of software architectures. To illustrate our case, we show how the theory of conceptual graphs could be a useful can...

In this paper, we introduce a benchmark suite on RTP/RTCP processing. The suite consists of three benchmarks, namely RTP Sender, RTP Receiver and RTCP Processing. For each benchmark, three aspects are specified: functions, measurements and environments. After implementing the benchmarks, we perform profiling in order to determine the time-critical functions and investigate the architectural cha...

The conceptual modelling of software architectures is of central importance for the quality of a software system. A rich modelling language is required to integrate the different aspects of architecture modelling, such as architectural styles, structural and behavioural modelling, into a coherent framework. We propose an ontological approach for architectural style modelling based on descriptio...

In this paper, we present a pattern-based software development method that preserves usability and security quality characteristics using a role-driven mapping of requirements analysis documents to architectural design artifacts. The quality characteristics usability and security are captured using specialized problem frames, which are patterns that serve to structure, characterize, and analyze...

This paper proposes an empirical approach to the visualization phase of architectural images, employing established concepts, methodologies, and measurement techniques found in media psychology and user-centered studies. The paper proposes a human-centered approach for conceptualizing visualization technologies and evaluating the quality concept of images to simulate a satisfactory architectura...

Simulation is important to verify the functional aspects of architectural design. We will introduce two examples of visual simulation techniques that deal with the simulation of emergency situations.

Introduction E-learning promises to play an important role in education. Whether this will lead to entirely virtual universities or, rather, will enable brick-and-mortar universities to adapt their educational offerings to new market expectations is too soon to predict. Currently, large IT multinationals are leading the e-learning evolution. They are recognizing the need for life-long learning ...

When a specific building is examined and analysed for its architectural merits, it is the visible, superficial aspects, which are considered, for example: aesthetics, function, spatial relationships, and landscape. One of the most important invisible factors that should be considered in the design process is the safety of buildings against natural hazards, particularly against earthquakes. Whil...

As microprocessor-based systems grow in complexity, and the processor-memory speed gap widens further, more emphasis needs to be placed on early design space exploration in order to produce the highest performance systems with minimal schedule impact. We discuss the critical issues associated with architectural evaluation of complex microprocessor-based systems, and present a methodology for th...
