Scheperboer, I. (author), Efthymiou, E. (author), Maljaars, J. (author)Aluminium plates containing a single hole or multiple holes in a row are recently becoming very popular among architects and consultant engineers in many constructional applications, due to their reduced weight, as well as facilitating ventilation and light penetration of the buildings. However, there are still uncertainties concerning their...conference paper 2016

(author), Haverkort, J.E.M. (author)Wurtzite gallium phosphide (WZ GaP) has been predicted to exhibit a direct bandgap in the green spectral range. Optical transitions, however, are only weakly allowed by the symmetry of the bands. While efficient luminescence has been experimentally shown, the nature of the transitions is not yet clear. Here we apply tensile strain up to 6% and...article 2016

Bakker, L.G. (author), Hoes-van Oeffelen, E.C.M. (author), Hordijk, G.J. (author), van de Ham, E.R. (author)Overheating in buildings is an increasingly important issue. Various studies show that local personalized cooling can substantially improve comfort levels while saving energy. Airflows are an efficient approach for local cooling. Fluctuating airflows seem more effective and are potentially perceived more comfortable compared to continuous...conference paper 2015

(author), Salvadori, A. (author)This paper presents a multiscale computational homogenization model for the post localization behavior of a macroscale domain crossed by a cohesive discontinuity emanating from microstructural damage. The stress-strain and the cohesive macroscopic responses are obtained incorporating the underlying microstructure, in which the damage evolution...article 2014

(author)Atmospheric turbulence is a well-known phenomenon that diminishes the recognition range in visual and infrared image sequences. There exist many different methods to compensate for the effects of turbulence. This paper focuses on the performance of two software-based methods to mitigate the effects of low-And medium turbulence conditions. Both...conference paper 2014
