Similar to refactoring, feature-oriented programming can be seen as a metaprogramming paradigm, in which programs are values and composition operators transform programs to programs. In this position paper we discuss open issues of applying refactoring in the context of feature-oriented programming. First, we elaborate on the role of refactoring in maintaining features and their implementations...

Purpose] We examined the improvement of hand function and activities of daily living in stroke patients after carrying out task-oriented training. [Subjects] Thirty-two patients who had been diagnosed with stroke and underwent rehabilitation therapy participated in the task-oriented training. [Methods] The participants carried out task-oriented training for 30 min per day for 4 weeks. Their han...

Case management comprises various complex activities. Consequently, case managers have to balance very diverging requirements and needs, while at the same time facing increasingly complex decisions. Case management software systems (CMS) provide capabilities such as information assessment and handling, decision and collaboration management as well as flexible process guidance to support case ma...

The interaction between the classes or within the classes shows the complexity of the design. For one smaller problem, there may be more than one software design but who will be the best; depends on the complexity level of software design. Therefore, coupling and cohesion which shows the interlinking of classes and strength of classes; control the complexity of the design. The best software obj...

Constraint Propagation can be speeded up significantly by choosing a good execution order for propagators. A propagator is an implicit representation of a constraint which is widely used in todays powerful constraint solvers. In this paper we evaluate different ways to find good execution orders automatically during runtime. We extend previous work in this area by two new techniques: fair-sched...

Many coupling measures have been proposed in the context of object-oriented (OO) systems. In addition, several studies have highlighted the complexity of using dependency analysis in OO software to perform impact analysis. The question is then: can we use simple decision models based on coupling measurement to support impact analysis in OO systems? Such an approach has for main advantage its si...

A parallel, object oriented Direct Simulation Monte Carlo (DSMC) solver is developed to study the impact of blast waves on arbitrary-shaped bodies. A very natural choice of classes is adopted to design the solver. A 3-D domain decomposition is used to parallalise the code. The Message Passing Interface (MPI) library is used to perform interprocessor communications. Preliminary results of two si...

Object-oriented (OO) software have complex dependencies and different change types which frequently affect their maintenance in terms of ripple-effects identification or may likely introduce some faults which are hard to detect. As change is both important and risky, change impact analysis (CIA) is a technique used to preserve the quality of the software system. Several CIA techniques exist but...

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...

The importance of service-oriented architecture for science is widely recognized. Increasingly, scientific communities are making information tools accessible as services that clients can access over the network, without knowledge of their internal workings. In this way, tools formerly accessible only to the specialist can be made available to all. Equally importantly, new value-added services ...
