Janssen, G.C.A.M. (author), Tichelaar, F.D. (author), Visser, C.C.G. (author)Stress in hard films is the net sum of tensile stress generated at the grain boundaries, compressive stress due to ion peening, and thermal stress due to the difference in thermal expansion of the coating and substrate. The tensile part due to grain boundaries is thickness dependent. The other two contributions are not thickness dependent....journal article 2006

Egyed, C.E.G. (author), Visser, H. (author)In het kader van het DOS-onderzoek naar onderhoud van wegen op slappe bodem, wordt er een afweegmodel ontwikkeld om te kijken welke constructie het beste is bij het ophogen van wegen. Hierin wordt een afweging gemaakt tussen de volgende ophoogmaatregelen: - traditioneel ophogen met ‘zwaar’ materiaal; - ophogen met toepassing van lichtgewicht...report 2006

Egyed, C.E.G. (author), Visser, H. (author), Willeboer, M.W. (author)Eén van de belangrijke onderdelen van het Delft Clusteronderzoek ‘Duurzame onderhoudsstrategie voor voorzieningen op slappe bodem’ is het maken van een keuzemodel. Met het model kan de meest optimale maatregel worden bepaald voor het opnieuw ophogen van de openbare ruimte. Voor de input van het model en voor het vastleggen van de aanwezige...report 2006

Liu, H. (author), Lühr, H. (author), Watanabe, S. (author), Köhler, W. (author), Henize, V. (author), Visser, P.N.A.M. (author)Using 3 years (2002–2004), over 16,400 orbits of measurements from the accelerometer on board the CHAMP satellite, we have studied the climatology of the equatorial zonal wind in the upper thermosphere. Several main features are noticed. The most prominent one is that the solar flux significantly influences both the daytime and nighttime winds....journal article 2006

Tuan, T.Q. (author), Verhagen, H.J. (author), Visser, P.J. (author), Stive, M.J.F. (author)To increase physical insight into wave overwash processes at low-crested beach barriers, wave overtopping discharge events rather than the conventional average overtopping discharge need to be quantified. Also, in order to make intelligent use of the many empirical formulations on wave overtopping discharge at breakwaters from literature, a...journal article 2006

Koning, P. (author), Noailly, J. (author), Visser, S. (author)This CPB Document provides a framework for the evaluation of non-profit organisations. This framework addresses the question under which conditions, and, if so, in what way non-profits should be stimulated. Essentially, in order to answer these questions, three steps can be followed: (i) identifying potentially relevant market failures that non...report 2006

Tuan, T.Q. (author), Verhagen, H.J. (author), Visser, P.J. (author)A hydrodynamic numerical model is formulated to describe the breach erosion process of sandy barriers. The breach flow is based on the system of unsteady shallow water equations, which is solved using a robust upwind numerical approach in conjunction with the Finite Volume Method (FVM). The hydraulic jump is considered as part of the breach flow...conference paper 2006

Tuan, T.Q. (author), Verhagen, H.J. (author), Visser, P.J. (author), Stive, M. (author)For management of coastal breaching hazards it is critical to be able to assess the potential of coastal barrier breaching as a result of wave actions during storm surges (wave overwash). This phenomenon is known as the breach initiation phase; the mechanisms behind this are not very well understood. In the present study, laboratory experiments...conference paper 2006

(author)Bij de aanleg én voor het beheer en onderhoud van gemeentelijke infrastructuur is de ondergrond een belangrijke kostenbepalende factor. Voor wegen speelt de draagkracht en vervorming van de bodem hierbij een belangrijke rol. Bijvoorbeeld een weg op een zandondergrond heeft minder intensief onderhoud nodig en heeft een langere levensduur dan op...report 2005

(author)In this paper, we present a systematic investigation of the influence of the deposition parameters on the deposition rate, etch rate, and mechanical stress of SiC films prepared by plasma-enhanced chemical vapor deposition (PECVD) technique. Among the relevant deposition parameters, the SiH4 gas flow rate, the main parameter to determine the Si...journal article 2005

Visser, P.N.A.M. (author), Sneeuw, N. (author), Gerlach, C. (author)A fast iterative method for gravity field determination from low Earth satellite orbit coordinates has been developed and implemented successfully. The method is based on energy conservation and avoids problems related to orbit dynamics and initial state. In addition, the particular geometry of a repeat orbit is exploited by using a very...journal article 2003
