While most design firms, professional artists, and educational programs continue to use conventional graphic modalities to communicate design intent and aesthetic expression, recent developments in computer graphics promise to revolutionize attitudes artists and designers now hold toward their work. Artists and designers will have to adopt new attitudes regarding the information utility of opti...

In analysis of the business and the system requirements, the identified elements are modeled using notations that fully describe their characteristics. Nevertheless, implicit relationships often exist between different types of elements that subsequently have to be identified and explicitly represented during the design of the system. This requires an in-depth analysis of the generated models o...

When applying RFID in production, it needs to be integrated into the used IT systems. However, till today system designers cannot rely on a standard solution for integrating RFID technology in manufacturing software systems. Each manufacturer has to deal with the same challenges: No consolidated findings on how to integrate RFID into the IT infrastructure exist. The consequence is that each IT ...

The Manager-Workers pattern is an architectural pattern for parallel programming, used when a design problem can be understood in terms of activity parallelism. This pattern proposes a solution in which the same operations are performed simultaneously and independently on different pieces of data. Operations carried out by each component are independent of operations by other components.

Quality goals have to be under a special consideration during software architectural design. Evolvability constitutes a quality goal with a special relevance for business critical systems. Architectural patterns can significantly contribute to the satisfaction of quality goals. But architectural design decisions regarding these goals have to be made in a systematic, methodical way and concernin...

Preserving the Quality of Architectural Tactics in Source Code by Mehdi Mirakhorli In any complex software system, strong interdependencies exist between requirements and software architecture. Requirements drive architectural choices while also being constrained by the existing architecture and by what is economically feasible. This makes it advisable to concurrently specify the requirements, ...

The need for a Prognostics and Health Management (PHM) system is propelled by increasing demand for condition based maintenance for systems to reduce cost of maintenance and mitigate risk. The use of multiple algorithms for PHM for a variety of systems presents challenges for PHM system developers in terms of integration and interfacing of various components, including hardware and software. A ...

This paper outlines some roles of knowledge while designing based on experimental results from studying novice and expert designers. The implications of these experimental results on future CAAD systems are discussed.

This paper proposes a set of architectural patterns for the design of interoperable image search&retrieval systems on top of the latest standards in the area, ISO/IEC 15938-12 (MPEG Query Format) and ISO/IEC 24800 (JPSearch). The work introduces the notion of a ‘‘composable metadata model’’ as a means to allow the usage of multiple metadata ontologies together, along with mechanisms to specify ...
