Towards intentional aesthetics within topology optimization by applying the principle of unity-in-variety

Topology optimization is increasingly applied to design consumer products, for which aesthetics plays an important role to consumer acceptance. In industrial design, it is known that preferences or taste judgement obey certain rules or principles. These principles are not directly quantifiable, but can qualitatively predict and explain...

Modeling the Structural Response of Reinforced Glass Beams using an SLA Scheme

This paper investigates whether a novel computational sequentially linear analysis (SLA) technique, which is especially developed for modeling brittle material response, is applicable for modeling the structural response of metal reinforced glass beams. To do so, computational SLA results are compared with experimental results of four-point...

Using Cluster Analysis to Improve the Design of Component Interfaces

A short (4-page) version of this paper is published in: ASE 2008 - 23rd IEEE/ACM International Conference on Automated Software Engineering, 15-19 September 2008; doi:10.1109/ASE.2008.54 For large software systems, interface structure has an important impact on their maintainability and build performance. For example, for complex systems written...

Using MDE for Generic Comparison of Views

We investigate the application of technologies for modeldriven engineering to check the conformance of two software models. This involves their model-based comparison, and visualisation of the results. To generalise our approach we use reflection, metamodel generalisation, and higher-order transformations. We apply our approach to assess the...

Model-driven evolution of software architectures

Software evolves continuously. As a consequence, software systems tend to become increasingly complex and, as such, more difficult to change. A software system's complexity is for a large part determined by its structure, or architecture. In this thesis we investigate how to reduce the risks and costs associated with the evolution of software...

Tool support for distributed software engineering

Developing a software system in collaboration with other partners, and on different geographical locations is a big challenge for organizations. In this article we first discuss a system that automates build and test processes: SoftFab. This system has been successfully applied in practice in the context of multi-site projects. Then, we discuss...

Visualisation of Domain-Specific Modelling Languages Using UML

Currently, general-purpose modelling tools are often only used to draw diagrams for the documentation. The introduction of model-driven software development approaches involves the definition of domain-specific modelling languages that allow code generation. Although graphical representations of the involved models are important for...

Model-driven Migration of Supervisory Machine Control Architectures

Supervisory machine control is the high-level control in advanced manufacturing machines that is responsible for the coordination of manufacturing activities. Traditionally, the design of such control systems is based on finite state machines. An alternative, more flexible approach is based on task-resource models. This paper describes an...

Analysis of high-Reynolds number wind-tunnel tests of the Semi-Spar

Aerodynamic load measurements were performed on a 1 : 50 scale model of the underwater part of the Semi-Spar concept in order to predict the loads exercised by the current on the full-scale structure. The test program comprised measurements with the model in even-keel as well as tilted conditions, in which also the effects of various ballast leg...
