De Vries, P. (author), Boelhouwer, P.J. (author)The literature on housing markets suggests that house prices in almost all western economies can be explained by short-run demand-oriented variables and a long- run term. The basic principles of the theory are that the short-run fluctuations, which are based on recent price developments (shocks), occur due to market imperfection, while over the...journal article 2009

De Vries, P. (author), Marien, A.A.A. (author)Woningcorporaties zijn maatschappelijke ondernemers. Zij streven naar empowerment; een term voor economische zelfstandigheid, perspectief op een passende wooncarrière, arbeidsparticipatie en zelfredzaamheid. Daarvoor zijn wel renderende investeringen noodzakelijk. Verondersteld wordt dat deze terugkomen als een waardestijging van de...journal article 2009

De Haan, J. (author), Van der Wal, E.B. (author), De Vries, P. (author)The sale price appraisal ratio (SPAR) method has been applied in a number of countries to construct house price indexes. This paper reviews the statistical and index number properties of the SPAR approach. Three types of SPAR indexes are distinguished: a weighted index, which aims at tracking the price change of the stock of owner-occupied...journal article 2009

De Vries, P. (author), De Haan, J. (author), Mariën, A.A.A. (author), Van der Wal, E. (author)Within the European Union there has been a push to provide European governments and the European Central Bank with the statistics they need for monitoring the owneroccupied sector. This paper reports on the results of a project to develop a house price index for the Netherlands. From January 2008, Kadaster, the Dutch land registry office, and...journal article 2009

De Vries, P. (author), Faber, R. (author)This paper examines the construction of real estate databases and the valuation of properties in Buzau, Romania. One of the criteria for candidate states for EU membership is an effective monitoring system for the land and real estate markets. The objective of this paper is twofold. First, the development of a set of databases, procedures and...journal article 2009

Ruijven, B. (author), Van der Sluijs, J.P. (author), Van Vuuren, D.P. (author), Janssen, P. (author), Heuberger, P.S.C. (author), De Vries, B. (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

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

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

(author)In addition to after-laying of new-installed high voltage (HV) power cables the use of on-site non-destructive on-site testing and diagnosis of service aged power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. In this paper based on field experience an...journal article 2008

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

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

Kuster, M. (author), De Vries, D. (author)It is commonly accepted that the sound reflections from real physical objects are much more complicated than what usually is and can be modelled by room acoustics modelling software. The main reason for this limitation is the level of detail inherent in the physical object in terms of its geometrical and acoustic properties. In the present paper...journal article 2007
