Although many countries have shown a distinct drop in crime over the last decades, the criminological literature suggests that fear of crime in those countries remained relatively stable. Research on this issue is sparse however, mostly confined to a single country, a few indicators and/or a relatively …

This work provides a feasibility study on estimating the 3-D locations of several thousand miniaturized free-floating sensor platforms. The localization is performed on basis of sparse ultrasound range measurements between sensor platforms and without the use of beacons. We show that this task can be …

Next to the manifestation of sensori-motor transformations such as singing and dancing, the ability to play an instrument by ear must rely on a unique convergence of cerebral functions involving motor preparation and auditory perception. In this study, we aimed to gain insight into the extent to which …

Crowdfunding is gaining popularity as a viable means to raise financial capital for good causes, cultural goods, new products, and ventures. Little empirical research has been done to understand crowdfunding and basic academic knowledge of its dynamics is still lacking. By data mining the crowdfunding …

Communities of Practice (CoPs) are social learning systems that can be, to a certain extent, designed. Wenger (1998) proposes the following paradox; “ no community can fully design the learning of another, but at the same time, no community can fully design its own learning” (p:234). My interpretation …

In a real-world environment a face detector can be applied to extract multiple face images from multiple video streams without constraints on pose and illumination. The extracted face images will have varying image quality and resolution. Moreover, also the detected faces will not be precisely aligned. …
