van Vliet, F.E. (author), Stulemeijer, J. (author), Benoist, K.W. (author), Smit, M.K. (author), TNO Fysisch en Elektronisch Laboratorium (author)The use of photonics for phased-array applications has been discussed for quity some time. Main difficulties up to now have been the component count and cost for relative complex systems. The advances in photonic integration are very promising to bring down both, as well as reduce volume and weight of phased-array beamforming networks as...conference paper 1999

Chen, C.-T. (author), Burton-Wurster, N. (author), Lust, G. (author), Bank, R.A. (author), Tekoppele, J.M. (author)The first objective of this study was to determine if the cumulative effects of impact or smoothly arising compression would damage the matrix of articular cartilage. Canine cartilage explants were subjected to repeated impacts or to smoothly arising compressions of as much as 20 MPa at 0.3 Hz for as long as 120 minutes. An increase in the water...article 1999

van Nijnatten, P.A. (author), Technisch Physische Dienst TNO - TH (author)Solar and visual light transmittance, colour appearance and other optical properties of glazing, are according to present standards specified for (near-) normal incidence. In general however, these properties are angular dependent. Realistic computation of visual light and solar energy properties therefore requires the angular behaviour to be...article 1999

Bijlaard, F.S.K. (author), TNO Bouw (author)This paper presents an overview of the structural assessment of existing structures in comparison to that of newly designed structures. The role of measuring geometrical data and testing the material properties is explained. The method provides objective criteria to judge the safety of existing structures.conference paper 1999

Luiijf, H.A.M. (author), TNO Fysisch en Elektronisch Laboratorium (author)Society is on the verge of a new era: the information age. Economical changes, a new way of looking at services and new types of conflict are forecasted. Some glimpses of these changes were noticed during the Persian Gulf War. Government decision units, organisations, society and critical industries become more and more inter-networked. They...conference paper 1999

(author), TNO Bouw (author)Within the use of alternative methods of probabilistic analysis and coming up computers with more CPU-power, today it Is possible within a design office, to analyse structures in a probabilistic way. After a pilot Implementation of some alternative methods in an existing FE-code, some structures are analysed in this way. DependIng on the FE code...conference paper 1999

van Winsum, W. (author), Martens, M. (author)In a driving simulator the effects of a prototype driver support system were tested on workload and driver behaviour. For these pu{poses, a number of critical incidents that were too dangerous to test on the road were simulated on a motorway. It was found that the critical incidents resulted in increased workload. Because of this, the workload...conference paper 1999

Tukker, A. (author), TNO Strategie, Technologie en Beleid (author)This paper (the second in a series of three) compares incineration options for hazardous waste with LCA. Provided that acceptance criteria are met with regard to metals, PAHs and chlorine, Dutch Municipal Solid Waste Incinerators (MSWIs) appeared to be preferable above rotary kilns since they have a better energy recovery and - unlike rotary...article 1999

Happee, R. (author), Loczi, J. (author)Both RAMSIS and MADYMO are widely applied for computer aided vehicle design. Both programs are used to simulate occupant-vehicle interactions where RAMSIS focuses on ergonomics in normal driving conditions and MADYMO focuses on passive safety in impact conditions. This paper describes simulations of human seat interactions using RAMSIS and...conference paper 1999
