Sharei Amarghan, H. (author), Alderliesten, Tanja (author), van den Dobbelsteen, J.J. (author), Dankelman, J. (author)Guidewires and catheters are used during minimally invasive interventional procedures to traverse in vascular system and access the desired position. Computer models are increasingly being used to predict the behavior of these instruments. This information can be used to choose the right instrument for each case and increase the success rate...review 2018

Verhoef, W. (author)A simple analytical four-stream radiative transfer model based on Suits's differential equations is applied to the atmosphere-earth system in order to investigate the effects of the atmosphere and the view angle on remotely sensed multispectral radiance data from vegetation canopies. This scene radiation model is composed of two atmospheric...report 1985

Schuring, J. (author)In order to obtain insight in the accuracy of automatic approaches, the symmetric motions of an aircraft, stabilized by autopilot and autothrottle, are simulated on an electronic analog computer. The aircraft tracks an I.L.S. glide path, being disturbed by I.L.S. beam bends, atmospheric turbulence and wind shear. The deviations of the aircraft...report 1973

Brouwer, M.P.A.M. (author), Pronk, Z. (author), Visser, F.B. (author), de Haas, J. (author)At the early beginning (1989) of implementation of the European User Support Organisation (USO) concept, development and implementation of a Dutch Utilisation Centre (DUC) started at NLR premises. After development of several pilot DUC facilities, DUC participated in a Columbus simulation mission and in the 2nd International Micro-gravity...report 1996

Prins, J.J.M. (author), Dieleman, P. (author), Hoogstraten, J.A. (author)The Hermes Manipulation System (HERA) will be an important part of the Hermes space plane system. The HERA is a sophisticated space manipulator system, which has to perform tasks ranging from capture and berthing to tool operation in various operational modes from fully automatic to purely manual. The HERA system main contractor is Fokker Space ...report 1987

van Woerkom, P.T.L.M. (author)Mathematical models of the dynamics of spacecraft are needed to carry out numerical simulations, to gain insight into the characteristics of the spacecraft dynamics, and to synthesize control algorithms suitable for online system Identification, estimation, and control. Increases in size and mechanical complexity of spacecraft result in...report 1985

van Woerkom, P.T.L.M. (author)For the simulation of rigid spacecraft manipulator dynamics there exists efficient recursive software. Extension of this software for the simulation of flexible spacecraft-manipulator dynamics would have important advantages. In this paper the method of Equivalent Flexibility Modelling (EFM) is outlined. Each flexible body is re-modelled as a...report 1989

Sewagudde, S. (author)The objective of this study is to develop a methodology for hybrid modelling of sedimentation in a coastal basin or large shallow lake where physically based and data driven approaches are combined. This research was broken down into three blocks. The first block explores the possibility of approximating a physically based model using a data...report 2008

Dekker, G.J. (author)Modern commercial transport aircraft contain digital avionics systems for more and more safety critical functions. The reliability and safety of those new systems depend on the hardware reliability and on the reliability of the embedded software. In this report, an overview is given of available methods and techniques to develop reliable...report 1982
