Signal and noise in Gravity Recovery and Climate Experiment (GRACE) observed surface mass variationsSchrama, E.J.O. (author), Wouters, B. (author), Lavallée, D.A. (author)The Gravity Recovery and Climate Experiment (GRACE) product used for this study consists of 43 monthly potential coefficient sets released by the GRACE science team which are used to generate surface mass thickness grids expressed as equivalent water heights (EQWHs). We optimized both the smoothing radius and the level of approximation by...journal article 2007

Ruessink, B.G. (author), Kuriyama, Y. (author), Reniers, A.J.H.M. (author), Roelvink, J.A. (author), Walstra, D.J.R. (author)We compare predictions of a coupled, wave-averaged, cross-shore waves-currents-bathymetric evolution model to observations of onshore and offshore nearshore sandbar migration. The observations span a 10- and 44-day period with onshore/offshore bar migration at Duck, North Carolina, and at Hasaki, Kashima Coast, Japan, respectively, a 3.5-month...journal article 2007

Breedveld, P. (author)The invention relates to an apparatus suitable for use in a space that is not easily accessible, comprising a distally provided head, which can be equipped with an inspection organ and/or intervention organ, and which is designed to be introduced into a cavitous body, a proximal control member remaining permanently outside the body, and a...patent 2007

Yan, B. (author), Pham, H.T.M. (author), Ma, Y. (author), Zhuang, Y. (author), Sarro, P.M. (author)The authors demonstrate a method for the fabrication of in situ ultrathin porous anodic aluminum oxide layers (aspect ratio<2:1) on Si, which can be directly used as templates for nanodot preparation and for pattern transfer. The regular shape of the aluminum oxide pores is maintained even when the thickness of the aluminum oxide template is...journal article 2007

Blankestijn, R.M.P. (author)Biological systems present a complexity beyond intuitive comprehension and to obtain a better understanding of the behaviour of the living organisms, large scale dynamic mathematical models are employed. From a system biology perspective, these models should not only describe the kinetic behavior of metabolic reaction networks that feature...master thesis 2007

Van de Pas, N. (author)Mathematical modeling of complex biochemical reaction networks can provide many clues for future (experimental) work. Challenge is to find these clues and to translate them into biological relevant properties. Studying signal transduction can explain how and why organisms respond to the extracellular conditions as they do. This topic is...master thesis 2007

Pullen, T. (author), Allsop, N.W.H. (author), Bruce, T. (author), Kortenhaus, A. (author), Schüttrumpf, H. (author), Van der Meer, J.W. (author)The manual has been intended to assist engineers who are already aware of the general principles and methods of coastal engineering. The manual uses methods and data from research studies around Europe and overseas so readers are expected to be familiar with wave and response parameters and the use of empirical equations for prediction. Users...report 2007

Durmisevic, S. (author), Ciftcioglu, O. (author)One building is more flexible in terms of use than the other and to determine how much a building ‘X’ is more flexible than a building ‘Y’ is a rather complex task. This research focuses on houses for the elderly in terms of future use, since the requirements have changed and many of the existing buildings do not meet new requirements. To asses...conference paper 2007

Politakis, G. (author)The mechanics of aeroelastic instabilities is particularly important in relation to the next generation of wind turbine designs. Sizes approaching the 10MW capacity will have a rotor diameter somewhere in the order of 170m. This could mean much higher loads and more flexible blade designs than current MW wind turbines, most probably resulting in...master thesis 2007

Anonymus, A. (author)Beschrijft de berekeningsmethoden en uitgangspunten die ten grondslag liggen aan de hydraulische randvoorwaarden en geeft voor elk dijkringgebied de hoogwaterstanden (de zogenaamde toets- en rekenpeilen). Voor de zee en estuaria zijn ook de golfrandvoorwaarden opgenomen. Errata toegevoegd met name voor de Maas.report 2007

Coussy, E. (author)The application of a hydrological rainfall-runoff scale model helps to illustrate hydrological processes better than a theoretical example on a black board. For this reason a first version of physical hydrological scale model was designed and built. The goal will be to build a second version which it is possible to move to be used for practical...report 2007

Williams, P. (author), Lansdorp, B. (author), Ockels, W. (author)Non-powered flight vehicles such as kites can provide a means of transmitting wind energy from higher altitudes to the ground via tethers. Although there have been many proposals for systems to extract wind energy from higher altitudes, this paper focuses on the use of a light lifting body at the end of a tether to generate useful power. Two...conference paper 2007

Amiri-Simkooei, A.R. (author), Tiberius, C.C.J.M. (author), Teunissen, P.J.G. (author)We propose a methodology to assess the noise characteristics in time series of position estimates for permanent Global Positioning System (GPS) stations. Least squares variance component estimation (LS?VCE) is adopted to cope with any type of noise in the data. LS?VCE inherently provides the precision of (co)variance estimators. One can also...journal article 2007

Dankelman, J. (author)With the introduction of minimally invasive surgery (MIS), it became necessary to develop training methods to learn skills outside the operating room. Several training simulators have become commercially available, but fundamental research into the requirements for effective and efficient training in MIS is still lacking.

Loef, R. (author), Schoonman, J. (author), Goossens, A. (author)Type transformation in CuInSe2 and CuInS2 solar cells is an important issue with far reaching consequences. In the present study, the presence of a p-n homojunction inside CuInS2 in a TiO2/CuInS2 device is revealed with a detailed impedance spectroscopy and capacitance study. A n-type CuInS2 film with a thickness of 40?nm is found at the TiO2 (n...journal article 2007
