STARE, a sonar data post-processing and visualisation software package

This paper presents STARE, a sonar-data post-processing and visualisation toot developed by TNO and written in Matlab 6.5. The software takes into account all available acoustic and non-acoustic data (GPS, radar, source/receiver position, time latencies, etc.). The latter can be used to get optimal position information for the identified sonar...

ERGOtool for the integral improvement of ergonomics and process flow in assembly

Manufacturers of manually assembled products are increasingly being forced to improve the flow of assembly orders, together with having more efficient employment, in order to meet increasing demands on short delivery times, high product variety, good quality and low manufacturing costs. At the same time, the human factor is increasingly...

Substrate noise generation in complex digital systems: Efficient modeling and simulation methodology and experimental verification

More and more system-on-chip designs require the integration of analog circuits on large digital chips and will therefore suffer from substrate noise coupling. To investigate the impact of substrate noise on analog circuits, information is needed about digital substrate noise generation. In this paper, a recently proposed simulation methodology...

PHASIM, an advanced phased array antenna software simulator

A sophisticated phased array simulator software package for the design and analysis of planar phased array antennas is presented. This package can accurately simulate the far-field characteristics of a large variety of planar phased array configurations in both the frequency and time domain. The simulator is coded in MATLAB version 5.3. Using...

Towards an Optimum Design of Energy Supply Systems

TNO-MEP developed and implemented an analysis method in a software tool called ODESSY. One of the major breakthroughs of the method is that it not only calculates possible energy saving achievements, but it will also generate an optimized heat exchanger network (HEN), including the positioning of heat pumps and CHP/utility heaters. The resulting...

PHASIM, a sophisticated phased array antenna software simulator implemented in MATLAB 5.2

A sophisticated phased array simulator software package for the design and analysis of planar phased array antennas is presented. This simulator is coded in MATLAB version 5.2. Using MATLAB, numerical engineering problems can be solved in a fraction of time of time required by programs coded in FORTRAN or C. This paper addresses an assessment of...

Stochastic finite element analysis of steel structures

The paper describes two well known but adapted methods for calculating the probability of failure of structures. First the First Order Reliability Method (FORM) is described using an adapted response surface. Secondly the Directional Sampling (DS) procedure is described using truncated stochastic distributions. Both methods are implemented in...

Dynamic assessment of the ecological risk of the discharge of produced water from oil and gas producing platforms

Since 1991 the North Sea countries (UK, Netherlands, Norway and Denmark) have put a lot of effort in the development of a decision support system for the legislation of the use and discharge of offshore exploration, drilling and production chemicals. The heart of this so-called 'harmonised mandatory control system' is the 'chemical hazard...

LPG rail tank cars under head-on collisions

This paper presents a general methodology for calculating the critical velocity of a train part striking the head of a LPG rail tank car. The energy dissipation during the collision is mainly due to collapse of the underframe, plastic deformation of the tank head and friction. The collapse behaviour of a two and four axle underframe is studied...
