Classical HPCN geared to application in industry

In The Netherlands as a result of a national HPCN initiative a Foundation HPCN was established in 1995. The purpose of this Foundation is to stimulate structural and lasting cooperation of universities, technological institutes and industry in economically relevant applications of HPCN. Projects have been selected and since the beginning of 1996...

ADAS structures module: Evaluation report

In a joint research project between the National Aerospace Laboratory (NLR) and the Faculty of Aerospace Engineering of Delft University of Technology (TUD) a multi-level system for the preliminary design of aircraft structures has been developed. The present system is essentially an extension of the existing Aircraft Design and Analysis System ...

DEFMEF predesign document

The predesign document of DEFMEF presents the decisive requirements for the DEFMEF language and the associated DEFMEF translator. It also shows a basic technical design, which fulfills the requirements. DEFMEF as a software design language has been designed so, that it is possible to describe both a technical design and a detailed design with it...

Dynamics motion simulation of the Hermes robot arm subjected to constraints

During operations with a manipulator arm situations will occur when the manipulator end-effector is, or comes, in contact with its environment. The dynamics equations, which describe the motion of the manipulator, can be represented by an ordinary differential equation for the free motion and an additional algebraic (in)equality for the motion...

De plaats van de wiskundige bij de ontwikkeling van digitale simulatie-systemen voor toepassingen uit de "Computational physics"

NLR mainly performs applied scientific research for use in the aerospace industry. In many cases the product has the form of an information system for the design, production and usage of aerospace vehicles. Within this context, the mathematician contributes, in cooperation with specialists from other disciplines such as aerodynamics, structures,...

The use of MEBAS in creating a simulation environment for compression and encryption

In order to get a better sight on the performance of compression and encryption algorithms under various conditions a simulation environment is needed. Within this simulation environment It must be possible to investigate the influence of code tables, channel characteristics and frame formats on the performance of the algorithms. In this report...

COLAS program generator and program generator generator

This manual describes the use of two tools for the development of software: - the COLAS Program Generator (CPG), which generates the complete control part of programs for interactive use from a specification of the user interaction. In addition the specifications needed for the COLAS command definition and stubs for the application routines are...

Simulation and optimization techniques in computer aided design

The use of numerical simulation and optimization techniques is rapidly expanding in all fields of engineering design. The place and the potential of these techniques in the design process, as well as their use by the designer, are discussed. The principles underlying these techniques are outlined and an overall view is given of the various...
