Meulenbroek, R.G.J. (author), Rosenbaum, D.A. (author), Jansen, C. (author), Vaughan, J. (author), Vogt, S. (author), TNO Technische Menskunde (author)Studies of human prehension have revealed characteristic patterns of grasping kinematics. We sought to gain insight into the determinants of those patterns by means of a computer simulation and accompanying behavioral experiment concerning multijoint, planar grasping behavior. The simulation was based on a recent theory of posture-based motion...article 2001

(author), Centraal Instituut voor Voedingsonderzoek TNO TNO Voeding (author)Over the past decades the description of quantitative structure-activity relationships (QSARs) has been undertaken in order to find predictive models and/or mechanistic explanations for chemical as well as biological activities. This includes QSAR studies in toxicology. In an approach beyond the classical QSAR approaches, attempts have been made...article 2001

(author)The TNO gastro-Intestinal tract Model (TIM) is a dynamic computer-controlled in vitro system that mimics the human physiological conditions in the stomach and small intestine. In the current TIM physiological parameters such as pH, temperature, peristaltic movements, secretion of digestion enzymes, bile and pancreatic juices, and absorption of...article 2000

Nederlands Instituut voor Toegepaste Geowetenschappen TNO Technisch Physische Dienst TNO - TH (author), Lamé, F. (author), Derksen, G. (author), Honders, T. (author), Gadella, M. (author), Maas, T. (author)Over the last three years the Centre for Soil Treatment has sampled 2570 soil stockpiles for the assessment of soil quality. For all stockpiles the same sampling strategy was used. 100 increments of approximately 180 grams were taken and collected into two batch samples. Appropriate sample pre-treatment and analyses resulted in two sets of...conference paper 2000

TNO Milieu, Energie en Procesinnovatie (author), Joziasse, J. (author), Bakker, T. (author), Eggels, P.G. (author)A decision support system for treatment of dredged sediments (DSTS) has been constructed, in which the environmental effects of various treatment options applied can be compared. The effects are evaluated by scores on environmental themes like global warming and acidification, using life cycle assessment methodology.conference paper 1998

Fountain, M.A. (author), Happee, R. (author), Wismans, J.S.H.M. (author), Lupker, H.A. (author), Koppens, W.P. (author), TNO Wegtransportmiddelen (author)In crash dummy models two different mathematical formulations can be distinguished: multibody techniques and finite element techniques. Both approaches offer their specific advantages and disadvantages. Multibody techniques are particularly attractive for the simulation of crash dummy segment motions and complex joint behavior. Finite element...conference paper 1996

Janssens, M.H.A. (author), Thompson, D.J. (author), Technisch Physische Dienst TNO - TH (author)The sound level of a train crossing a steel railway bridge is usually about 10 dB higher than on plain track. In the Netherlands there are many such bridges which, for practical reasons, cannot be replaced by more intrinsically quiet concrete bridges. A computational model is described for the estimation of noise levels due to a train crossing a...article 1996

Dekker, H.J. (author), Sturm, W.L. (author), TNO Wegtransportmiddelen (author)A dynamic model of a Heavy Duty (HD) turbocharged and aftercooled diesel engine was developed. The engine was equipped with high pressure diesel injection, a Variable Geometry Turbine (VGT) and an Exhaust Gas Recirculation (EGR) system. This engine was targeted at meeting EURO4 emission requirements. The final emission results were 2.4 g/kWh NOx...conference paper 1996

(author), Prins Maurits Laboratorium TNO (author)A summary is given of part of the CEC co-sponsored project MERGE (Modelling and Experimental Research into Gas Explosions). The objective of this part of the project was to provide improved Computational Fluid Dynamic explosion models with the potential for use in hazard assessments.
