Serajeh, R. (author), Khademi, S. (author), Mousavinia, Amir (author), van Gemert, J.C. (author)This paper investigates sensitive minima in popular deep distance learning techniques such as Siamese and Triplet networks. We demonstrate that standard formulations may find solutions that are sensitive to small changes and thus do not generalize well. To alleviate sensitive minima we propose a new approach to regularize margin-based deep...journal article 2020

Krietemeyer, A. (author), ten Veldhuis, Marie-claire (author), van der Marel, H. (author), Realini, Eugenio (author), van de Giesen, N.C. (author)Dual-frequency Global Navigation Satellite Systems (GNSSs) enable the estimation of Zenith Tropospheric Delay (ZTD) which can be converted to PrecipitableWater Vapor (PWV). The density of existing GNSS monitoring networks is insufficient to capture small-scale water vapor variations that are especially important for extreme weather...journal article 2018

Verhees, Bart (author), van Kuijk, Kees (author), Simonse, LWL (author)Point-of-care testing (POCT)—laboratory tests performed with new mobile devices and online technologies outside of the central laboratory—is rapidly outpacing the traditional laboratory test market, growing at a rate of 12 to 15% each year. POCT impacts the diagnostic process of care providers by yielding high efficiency benefits in terms of...journal article 2018

Nourian Ghadikolaee, P. (author), Goncalves, R. (author), Zlatanova, S. (author), Arroyo Ohori, G.A.K. (author), Vu Vo, A. (author)Voxel representations have been used for years in scientific computation and medical imaging. The main focus of our research is to provide easy access to methods for making large-scale voxel models of built environment for environmental modelling studies while ensuring they are spatially correct, meaning they correctly represent topological and...journal article 2016

Paiman (student), Charlotte (author), Lemus Perez, D.S. (author), Short Sotero, D.M. (author), Vallery, H. (author)The occurrence of falls is an urgent challenge in our aging society. For wearable devices that actively prevent falls or mitigate their consequences, a critical prerequisite is knowledge on the user’s current state of balance. To keep such wearable systems practical and to achieve high acceptance, only very limited sensor instrumentation is...journal article 2016

Sirmacek, B. (author), Lindenbergh, R.C. (author)Recent technological developments help us to acquire high quality 3D measurements of our urban environment. However, these measurements, which come as point clouds or Digital Surface Models (DSM), do not directly give 3D geometrical models of buildings. In addition to that, they are not suitable for fast 3D rendering. Therefore, detection and 3D...journal article 2015
