Towards Model-Driven Requirements Analysis for Context-Aware Well-Being Systems

18-09-2012 § Leave a comment

Abstract

Over the years, the interest in the field of pervasive computing has increased. A specific class of applications in this domain is that of context-aware applications. These programs utilize context information to adapt to their current environment. This quality can be used, among others, when dealing with health care and well-being situations. However, as the user requirements for these specific applications are almost never well-specified, there is a real risk that the resulting application does not offer the right set of features to the user. In order to mitigate this risk, we propose a model-driven method of requirements engineering for systems in the domain of context-aware well-being applications. This method will result in an explicit specification of requirements, and an improved alignment of user requirements and system features. Furthermore, due to the model-driven character of the method, the artifacts created during the requirements engineering phase of the development process can directly be incorporated in the subsequent development steps

A Ubiquitous System for Smart Reasoning for Well-Being at Home and at Work

02-03-2012 § Leave a comment

Abstract

The lifestyle of the Dutch workforce is degrading. Unhealthy habits cause both physical and psychological problems, putting a strain on the individual’s well-being. In order to conquer both of these, a system will be created that will coach its user to improve their lifestyle through a better diet and
promoting physical activity in order to improve their feeling of well-being. However, requirements engineering is troublesome in this domain. We propose ways to conquer these requirements engineering problems using model-driven engineering techniques.

Performance in Model Transformations: Experiments with ATL and QVT

28-11-2011 § Leave a comment

Abstract

Model transformations are increasingly being incorporated in software development processes. However, as systems being developed with transformations grow in size and complexity, the performance of the transformations tends to degrade. In this paper we investigate the factors that have an impact on the execution performance of model transformations. « Read the rest of this entry »

A Performance Analysis of Model Transformations and Tools

28-11-2011 § Leave a comment

Abstract

Model-Driven Engineering is a software development process that has gained popularity in the recent years. Unlike traditional software engineering processes, MDE is centered around models, instead of code. By using model transformations, models can be translated from one language to another, resulting in a separation of program architecture and execution platform. However, an increase in size of any of the elements required by the transformation process might lead to performance problems. Although these problems are common and well known in the eld of software engineering, problems speci c to MDE have not yet been investigated in suffcient depth. « Read the rest of this entry »
