A Hybrid Approach to Combine Physically Based and Data-Driven Models in Simulating Sediment Transportation

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...

Development and operations in the Dutch utilisation centre

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...

The approach for the development of simulators at the National Aerospace laboratory (NLR): Two space related examples

Couwenberg, M.J.H. (author), ten Dam, A.A. (author), Mans, M.T.G.A.R. (author)

Simulation plays an increasingly important role during several stages and several types of space related projects, ranging from engineering support simulators to training simulators. Therefore it is required to have a common basis for the definition, the development and, finally, the use of simulators. In this paper the approach for the...

Equivalent flexibility modelling: A novel approach towards recursive simulation of flexible spacecraft-manipulator dynamics

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...

Numerical accuracy of a two-stream radiative transfer model from comparison with an N-stream model

Verhoef, W. (author)

In the past, a relatively simple radiative transfer model, based on scattering and extinction of two semi-isotropic diffuse fluxes and two direct fluxes (solar beam and radiance in the viewing direction), has been applied to vegetation canopies and to the atmosphere. This model takes little computing power, but its numerical accuracy had not yet...

The Hermes manipulation system (HERA) simulation facility development

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 ...
