Brinkman, W.P. (author), Hoekstra, A.R.D. (author), Van Egmond, R. (author)Three studies were conducted to examine the effect of audio on people's experience in a virtual world. The first study showed that people could distinguish between mono, stereo, Dolby surround and 3D audio of a wasp. The second study found significant effects for audio techniques on people's self-reported anxiety, presence, and spatial...conference paper 2015

Trajanovski, S. (author), Kuipers, F.A. (author), Hayel, Yezekael (author), Altman, Eitan (author), Van Mieghem, P.F.A. (author)Forming, in a decentralized fashion, an optimal network topology while balancing multiple, possibly conflicting objectives like cost, high performance, security and resiliency to viruses is a challenging endeavor. In this paper, we take a game-formation approach to network design where each player, for instance an autonomous system in the...conference paper 2015

Salauddin, M. (author), Broere, A. (author), Van der Meer, J.W. (author), Verhagen, H.J. (author), Bijl, E. (author)A new and symmetrical single layer armour unit, the crablock, has been designed in the UAE. One breakwater was reconstructed with crablock, but very limited testing had been performed. Just to become more acquainted with this new unit, pre-competitive research at a university has been performed, which is the subject of this paper. Being a new...conference paper 2015

Fuchs, P.S. (author), Lele, A. (author), Venkatesha-Prasad, R.R. (author)The Indian Energy grid is growing rapidly and there is a large simulation to improve not only the grid reliability, but also provide power for all by 2027. To this aim the Government of India has launched the Restructured Accelerated Power Development Program (RAPDRP). In India, residential loads contribute to about 27% of the total power...conference paper 2015

Green, D. (author), Hodkiewicz, M. (author), Masschelein, S. (author), Schoenmaker, R. (author), Muruvan, S. (author)Setting targets is a common way for organisations to establish performance expectations. However the validity of targets is challenged when performance is influenced by factors beyond the control of the manager. This project examines the issue of target setting for a single asset performance measure across different geographical areas. The...conference paper 2015

(author)Powered by WebGL, some renderers have recently become available for the visualization of point cloud data over the web, for example Plasio or Potree. We have extended Potree to be able to visualize massive point clouds and we have successfully used it with the second national Lidar survey of the Netherlands, AHN2, with 640 billion points. In...conference paper 2015

Kamerling, M.W. (author)This paper describes a proposal to renovate a Fusee Ceramique Barrel Vault with steel diagonals In 1956 two workshops, varying in height and span, were built in Wormerveer, The Netherlands. Both workshops were roofed with a concrete barrel vault with a thickness of 110 mm. The cylindrical vaults were constructed with Fusée Ceramique elements. A...conference paper 2015

Biljecki, F. (author), Arroyo Ohori, K.

We elaborate on their differences and on the challenges involved in their conversion, such as the inference of semantics in an...conference paper 2015

Peters, R. (author), Ledoux, H. (author), Biljecki, F. (author)Visibility analysis is an important application of 3D GIS data. Current approaches require 3D city models that are often derived from detailed aerial point clouds. We present an approach to visibility analysis that does not require a city model but works directly on the point cloud. Our approach is based on the medial axis transform, which...conference paper 2015

This seems also the case with sustainable building projects. It is therefore necessary that project managers are trained to deal with these problems, especially by learning from their...conference paper 2015
