Tokovinin, A. (author), Thomas, S. (author), Vdovin, G. (author)Membrane micro-machined deformable mirrors (MMDM) feature low cost, low power consumption, small size and absence of hysteresis. Interested in using such a device for the adaptive optics system at the SOAR 4.1-m telescope, we evaluated the performance of a 79-channel 50-mm (pupil size 35mm) MMDM from OKO Technologies. The measured influence...conference paper 2004

Mota, N.J.A. (author)Designing Self-help sounds like a contradiction in terms. Indeed, a great deal of the scholarly accounts on self-help housing excludes the agency of the designer, stressing instead the roles of the policy maker and the owner-builder. In the architecture discipline, from the late 1950s through the 1980s the notions of open form, group form and...conference paper 2015

Schipper, H.R. (author), Grünewald, S. (author), Eigenraam, P. (author), Raghunath, P. (author), Kok, M.A.D. (author)Free-form buildings tend to be expensive. By optimizing the production process, economical and well-performing precast concrete structures can be manufactured. In this paper, a method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single element. The...conference paper 2014

Fu, B. (author), Uhlig, S.P.W.G. (author)The evaluation of dynamic Traffic Engineering (TE) algorithms is usually carried out using some specific network(s), traffic pattern(s) and traffic engineering objective(s). As the behavior of a TE algorithm is a consequence of the interactions between the network, the traffic demand and the algorithm itself, the relevance of TE may depend on...conference paper

Spruit, R. (author), Van Tol, F. (author), Broere, W. (author)If a calamity with a retaining wall occurs, the impact on surrounding buildings and infrastructure is at least an order of magnitude more severe than without the calamity. In 2005 and 2006 major leaks in the retaining walls of underground stations in Amsterdam and Rotterdam occurred. After these cases had been thoroughly studied it was concluded...conference paper 2015

Lousberg, L.H.M.J. (author)Research shows that there are many bottle-necks in Public Private Partnership (PPP) Projects in Dutch spatial development. Due to the specific properties of Public Private Partnerships, these bottle-necks can lead to dysfunctional conflicts which are damaging the project. Hence the question is: how to prevent these conflicts? Literature doesn?t...conference paper 2011

They can be regulated through organizations similar to human organizations, which regulate the agents' behavior space and describe the expected behavior of the agents. Agents need...conference paper 2014
