Augenbroe, G. (author), de Wit, M.S. (author), TNO Bouw (author)Expert judgement studies are a relatively new way of quantifying technical uncertainty in engineering design. Unfortunately they can be time-consuming and costly because they require physical meetings between a group of possibly widely dispersed experts.This paper investigates how web-hosted collaboration or `virtual teaming' can be used to...conference paper 2002

Centraal laboratorium TNO (author)This book owes its conception to an Advanced Research Institute held in the Netherlands, 24-30 September 1978, under the sponsorship of the ECo-Sciences Panel of the NATO Science Committee. IE was attended by 35 experts from 12 NATO as welI as non-NATO countries.conference paper 1979

(author)The defense and security community have to cope with threats in complex environments that are merged in the scene context. The aim of this study is to investigate if fusion of Gated Viewer images with traditional thermal IR images provides a solution for threat recognition (with context understanding) in complex environments; and if contextual...conference paper 2014

Weiss, M. (author)The problem of evaluating the performance of an uncertain guidance loop system is considered, when the uncertainty is described in terms of an integral quadratic constraint. The idea of the approach proposed in this paper is to determine the set of all possible state vector values at the end of the flight that are compatible with the model...conference paper 2010

van Erp, J.B.F. (author), Veltman, J.A. (author), van Veen, H.A.H.C. (author), TNO Technische Menskunde (author)We tested the effect of a tactile torso display on keeping an instructed altitude during low level flight. The tactile instrument consisted of 64 vibrating elements attached to the torso, shoulders and thighs of the pilot. In a helicopter simulator, 12 student pilots flew under different conditions of vision (full vision and night vision) and...conference paper 2003

(author)This paper shows that it is possible to simulate realistic shallow-water acoustic communication channels using available acoustic propagation models. Key factor is the incorporation of realistic time-dependent sea surface conditions, including both waves and bubbles due to wind.conference paper 2013

Mantel, O.C. (author), Oostveen, J.C. (author), Popova, M.P. (author), TNO Informatie- en communicatietechnologie (author)Deterministic propagation models based on ray tracing or ray launching are widely studied in the scientific literature, because of their high accuracy. Also many commercial propagation modelling tools include ray-based models. In spite of this, they are hardly used in commercial operations by cellular operators. In this article we study the...conference paper 2007

Closed loop control of laser welding using an optical spectroscopic sensor for Nd:YAG and CO2 lasersKonuk, A.R. (author), Aarts, R.G.K.M. (author), Huis in 't Veld, A.J. (author), Sibillano, T. (author), Rizzi, D. (author), Ancona, A. (author)Recent developments in laser joining show the applicability of spectral analysis of the plasma plume emission to monitor and control the quality of weld. The analysis of the complete spectra makes it possible to measure specific emission lines which reveal information about the welding process. The subsequent estimation of the electron...conference paper 2011

Jacobs, J. (author), Verhoeve, R. (author), Cappon, H.J. (author), Rutjes, N. (author), Wismans, J.S.H.M. (author), TNO Industrie en Techniek (author)Physical crash test dummies of one type, such as the ES-2 side impact dummy, are not perfectly reproducible due to production and certification tolerances. This means that similar crash tests with various ES2 dummies will have varying results, called experimental scatter. New car designs should be insensitive to this scatter, thus the design is...conference paper 2006

The overall impact will be studied in combination with a multi-rate system approach. A reconstruction and anti-aliasing filter will be selected and its parameters will be...conference paper 2006

(author), TNO Industrie en Techniek (author)Corrosion and erosion are two major degradation mechanisms of piping systems and pipelines that both lead to wall thickness loss. To ensure sufficient integrity levels of these assets NDE is currently conducted at time based intervals often associated with shut downs. However, both economical and social requirements are pushing the industry to...conference paper 2009

(author)The bottleneck in situation awareness is no longer in the sensing domain but rather in the data interpretation domain, since the number of sensors is rapidly increasing and it is not affordable to increase human data-analysis capacity at the same rate. Automatic image analysis can assist a human analyst by alerting when an event of interest...conference paper 2016

This is accomplished by the coupling of a series of signalized intersections. This is an advantage for driver comfort, for flow and safety on the road network, and for the environment.
