The IT-for-Green project aims at developing the next generation of Corporate Environmental Management Information Systems (CEMIS). Green IT being one important aspect of this, the ITfor-Green project seeks to support the analysis of a given data center situation and to support the simulation of alternative architectures to find ways to increase energy efficiency. To facilitate this, we develop ...

Designers often want the added flexibility of having both quads and triangles in their models. It is also well known that triangle meshes generate poor limit surfaces when using a quad scheme, while quadonly meshes behave poorly with triangular schemes. Further, regular subdivision produces smooth surfaces even from sharp-cornered base meshes and sometimes sharpness in the subdivision surface i...

This paper presents a new construct: the conceptual tool ‘Flexibility’. The construct was a result of an attempt to extract experiences of teaching and learning with the use of laptops. It was further developed and refined on the basis of four small-scale teaching experiments. The teaching experiments, being part of a development project in upper secondary school mathematics, investigated the u...

A fi rewall is a collection of components interposed between two networks that fi lter traffi c between them according to some security policy [1]. Typically, fi rewalls rely on restrictions in the network topology to perform this fi ltering. One key assumption under this model is that everyone on the protected network(s) is trusted, since internal traffi c is not seen by the fi rewall and thus...

By blending storytelling with topics in biology, a fun activity can be created for students to strengthen their scientific knowledge (1-3). The “Sci-Fi Microbe” writing assignment lets students create an altered version of a known microorganism, and write a story describing an unusual observation that leads the characters discovery of their new microorganism. The Sci-Fi Microbe exercise is appr...

The paper provides insights on how wikis support project work and what characteristics of wikis make them adequate for this purpose. The findings are based on a case study of software engineering projects in an educational setting. Project wikis are found to serve an integrative role along several dimensions of project work, enabled by the flexibility and automatic support for capturing history...

Psychosocial stress influences cognitive abilities, such as long-term memory retrieval. However, less is known about the effects of stress on cognitive flexibility, which is mediated by different neurobiological circuits and could thus be regulated by different neuroendocrine pathways. In this study, we randomly assigned healthy adults to an acute stress induction or control condition and subse...

Statement of purpose: The purpose of these working papers is to promote the circulation of research results (Research Series) and analytical studies (Documents Series) made within the National Bank of Belgium or presented by external economists in seminars, conferences and conventions organised by the Bank. The aim is therefore to provide a platform for discussion. The opinions expressed are st...
