Software frameworks typically constitute a semi-finished software architecture for a complex application domain that can be adapted to the needs and requirements of a concrete application in the domain. Since the introduction of objectoriented frameworks in the late eighties, the development of software frameworks is still costly and difficult to handle. To reduce development risk, process mode...

Commercial software component models are frequently based on object-oriented concepts and terminology with appropriate binding, persistence and distribution support. In this paper, we argue that a process-oriented view on cooperating software components based on the concepts and terminology of a language/action perspective on cooperative work provides a more suitable foundation for the analysis...

This paper discusses the design of a hierarchically structured process planning system for a printed circuit board assembly hne. BasIcally. the assembly system consists of a series of mdependently operatmg placement modules, connected by a carrlerless conveyor system. Both the modules and the conveyor system are fully automated, while the complete system 1s also under centrahzed computer contro...

We propose a computational model for the Component Process Model (CPM) of Scherer, the most recent and the most complete model of emotion in psychology. This one proposes to appraise a stimulus through a sequence of sixteen appraisal variables dealing with a large number of its characteristics. As CPM is very abstract and high level, it is not really used in affective computing and no formal mo...

Many reengineering approaches have focused on extracting an abstract representation through syntax analysis of legacy source codes. So, recovery of rationale behind the design decision, such as domain specific semantics and roles, has been ignored. In this paper, we suggest the architecture based reengineering approach using design patterns. A design pattern, as core element of software archite...

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...

The ability to acquire a cognitive and motor skill was investigated in 20 older and 20 younger participants using repeated testing on the Tower of Toronto (TT) puzzle, a variant of the Tower of Hanoi. Explicit memory, perceptual priming, and sustained attention were also assessed. Older subjects exhibited a defective cognitive skill performance despite the fact that cognitive skill learning suf...
