Neumann, N.M.P. (author), den Breeijen, S.R. (author)Different algorithms can be used for clustering purposes with data sets. On of these algorithms, uses topological features extracted from the data set to base the clusters on. The complexity of this algorithm is however exponential in the number of data points. Recently a quantum algorithm was proposed by Lloyd Garnerone and Zanardi with claimed...article 2019

Lo Bue, S. (author), Kintaert, S. (author), Taverniers, J. (author), Mylle, J. (author), Delahaij, R. (author), Euwema, M. (author)Hardiness is a personality trait that drafts courage and motivation during adversity. Research showed that hardiness differentiates elite athletes from their lower rank competitors. In the domain of sport psychology, hardiness also strongly predicts physical performance. Because the military occupation requires resilience and excellence in...article 2018

de Greeff, J. (author), Hindriks, K. (author), Neerincx, M.A. (author), Kruijff-Korbayova, I. (author)The TRADR project aims at developing methods and models for human-robot teamwork, enabling robots to operate in search and rescue environments alongside humans as teammates, rather than as tools. Through a user-centered cognitive engineering method, human-robot teamwork is analyzed, modeled, implemented and evaluated in an iterative fashion....conference paper 2015

(author)Long-term tracking is important for maritime situational awareness to identify currently observed ships as earlier encounters. In cases of, for example, piracy and smuggling, past location and behavior analysis are useful to determine whether a ship is of interest. Furthermore, it is beneficial to make this assessment with sensors (such as...conference paper 2014

(author)For maritime situational awareness, it is important to identify currently observed ships as earlier encounters. For example, past location and behavior analysis are useful to determine whether a ship is of interest in case of piracy and smuggling. It is beneficial to verify this with cameras at a distance, to avoid the costs of bringing an own...conference paper 2014

(author)This paper reports a study on the use of satellite radar data to constrain the subsurface model parameters of the Bergermeer gas field. Using PSI (Persistent Scatterer InSAR) technology, ascending and descending data were applied in line-of-sight geometry, i.e., without first unravelling the horizontal and vertical components of the signal. The...conference paper 2013

van den Broek, S.P. (author), Schwering, P.B.W. (author), Liem, K.D. (author), Schleijpen, H.M.A. (author)In maritime operational scenarios, such as smuggling, piracy, or terrorist threats, it is not only relevant who or what an observed object is, but also where it is now and in the past in relation to other (geographical) objects. In situation and impact assessment, this information is used to determine whether an object is a threat. Single...conference paper 2012

Poot, A. (author), Quik, J.T.K. (author), Veld, H. (author), Koelmans, A.A. (author), TNO Bouw en Ondergrond (author)Black Carbon (BC) quantification methods are reviewed, including new Rock-Eval 6 data on BC reference materials. BC has been reported to have major impacts on climate, human health and environmental quality. Especially for risk assessment of persistent organic pollutants (POPs) it is important to account for risk reduction caused by BC, as...article 2009
