De Vries, D. (author), Hörchens, L. (author), Grond, P. (author)The state of the art of wave field synthesis (WFS) systems is that they can reproduce sound sources and secondary (mirror image) sources with natural spaciousness in a horizontal plane, and thus perform satisfactory 2D auralization of an enclosed space, based on multitrace impulse response data measured or simulated along a 2D microphone array....journal article 2007

Personalization allows users to browse programs much more efficiently according to their taste. It also enables to build social networks that can improve the performance of current P2P systems considerably, by increasing content availability, trust and the...journal article 2007

De Vries, J.C. (author)Steeds vaker wordt vastgoed gebruikt om op een of andere wijze de prestatie van de organisatie te verbeteren. Bijvoorbeeld door een verbeterde uitstraling, een kostenreductie of verhoging van de motivatie van medewerkers. Probleem is dat niet op te maken is in hoeverre de effecten het gevolg zijn van de vastgoedingreep of van een verandering in...doctoral thesis 2007

Developing a House Price Index for The Netherlands: A Practical Application of Weighted Repeat SalesJansen, S.J.T. (author), De Vries, P. (author), Coolen, H.C.C.H. (author), Lamain, C.J.M. (author), Boelhouwer, P.J. (author)This paper describes the development of a house price index that has been introduced in May 2005 in The Netherlands. This monthly index, called Woningwaarde Index Kadaster (House Price Index Kadaster), is designed to detect changes in the price of the overall stock of owner-occupied homes. Fifty-five indices are calculated: one overall index,...journal article 2007

De Vries, M. (author)Consider the set U of real numbers q >= 1 for which only one sequence (c(i)) of integers 0 <= c(i) <= q satisfies the equality Sigma(infinity)(i= 1) ciq(-i) =1. We show that the set of algebraic numbers in U is dense in the closure (U) over bar of U.journal article 2007

Wang, J. (author), Robertson, S. (author), De Vries, A.P. (author), Reinders, M.J.T. (author)Collaborative filtering is concerned with making recommendations about items to users. Most formulations of the problem are specifically designed for predicting user ratings, assuming past data of explicit user ratings is available. However, in practice we may only have implicit evidence of user preference; and furthermore, a better view of the...journal article 2008

(author)The objective of this paper is to demonstrate the use of Stereo Photogrammetry (SP) measuring ship-generated waves and to determine under which conditions they are suitable for surfing. A physical experiment is conducted to gain insight in ship wave behavior under specific conditions. Waves are generated by a hull and are measured using SP. It...conference paper 2008

(author)SPEX (Spectropolarimeter for Planetary EXploration) is an innovative, compact remote-sensing instrument for detecting and characterizing aerosols. With its 1-liter volume it is capable of full linear spectropolarimetry, without moving parts. High precision polarimetry is performed through encoding the degree and angle of linear polarization of...conference paper 2008

De Vries, G. (author)“Waarom leggen we de daken niet vol zonnecellen? Dan is het energieprobleem zo opgelost.” Een aantrekkelijke gedachte, maar nog steeds geen praktijk. Dat komt door hoge productiekosten en een relatief laag rendement. In het Joint Solar Programme van FOM wordt gewerkt aan materialen die een groter deel van het erop vallende licht omzetten in...journal article 2008

Van der Veen, R.A.C. (author), De Vries, L.J. (author)The share of microgeneration (power generation at the level of households and small businesses) in the Dutch electricity system continues to grow. Over time, this development may pose a threat to the reliability and efficiency of the Dutch electricity balancing market. We investigated possible changes to the design of the Dutch balancing market...journal article 2009

(author)In this paper a new wave pool concept is presented using ship hulls as wave generators. To evaluate the potential of such a concept a towing tank experiment is conducted to investigate ship wave generation in a confined space. In the towing tank experiment various hull sizes and velocities are examined to maximize the generated wave height. The...conference paper 2009

(author)Uncertainties in energy demand modelling originate from both limited understanding of the real-world system and a lack of data for model development, calibration and validation. These uncertainties allow for the development of different models, but also leave room for different calibrations of a single model. Here, an automated model calibration...journal article 2009

Broekens, D.J. (author), Kosters, W.A. (author), De Vries, T. (author)During the past several decades, much research has been done in the field of visual attention and cognitive processing, i.e., how does the human brain process visual stimuli. We show that the card game SET is a good candidate for investigating the relation between top-down versus bottom-up visual information processing. Further, we show that...conference paper 2009
