Elderly participants experiencing difficulty in chair rising and with a maximum knee-extensor torque below 87.5 N · m were randomized to different versions of a strength-training program for the knee-extensors: to a high-guidance group (HG; two group sessions supervised by a physical therapist and one unsupervised home session per week, n = 17),...

More than 80 000 residents' responses to transportation noise from 42 studies conducted at different times of year provide statistical estimates of the effects of season and meteorological conditions on community response to noise. The strongest evidence for a seasonal effect comes from 7 years of continuous daily interviewing of nationally...

The sensitivity of sound speed to temperature makes it possible to use an echo sounder as a thermometer, provided that the salinity and water depth are known with sufficient precision. Could ‘echothermometry’ – i.e., the use of an echo sounder, or a network of echo sounders, to measure temperature in this way – provide a viable alternative to...

The effects of human-machine interface (HMI) design for intelligent speed adaptation (ISA) on driving behavior and acceptance were measured in a moving-base research driving simulator. Sixty-four experienced drivers participated in two simulator experiments (32 in each). During the simulated runs with ISA, the speed limit was communicated...

TNO executed a technology demonstration programme in co-operation with RWMS on the application of solid fuel ramjet propulsion technology to medium calibre air defence projectiles. From 2000 to 2004 a complete and integrated structural and aero-thermodynamic projectile design was conceived satisfying the gun related requirements on projectile...

The computer program PHATAS, ”Program for Horizontal Axis wind Turbine Analysis and Simulation”, is developed for the time-domain calculation of the dynamic behaviour and the corresponding loads on a Horizontal Axis wind Turbine, HAT. The program PHATAS is available for use as ”console application” on a PC operating under MS-Windows, on a UNIX...

This paper describes the influence on vehicle emissions and energy consumption of different vehicle parameters and driving style as well as of traffic measures taken in order to increase transport safety or to reduce traffic jams. This should allow the Flemish Regional Government to perform more realistic modelling of the impact of transport on...

The ducted rocket is a supersonic flight propulsion system that takes the exhaust from a solid fuel gas generator, mixes it with air, and burns it to produce thrust. To develop such systems, the use of numerical models based on computational fluid dynamics (CFD) has been increasing, but to date only simplified treatments of the combustion within...

We have developed a new interrogation/demultiplexing system for Fiber Bragg Grating (FBG) sensor array. Our approach combines a high readout frequency for all the FBG sensor channels with absolute measurement. This combination is in particular of interest for the detection of dynamic loading, which is the main cause of hair cracks development in...

In order to find an optimal scanning strategy we determined the relationship between search performance and several scanning- and scene parameters in human observer experiments. The observers searched with a limited field of view (FOV) through a large search sector for a target (a camouflaged person) on a heath. From trial to trial the target...

A fiber optic interferometer comprising of a Sagnac interferometer and a Mach-Zehnder interferometer was developed. The interferometer enabled detection of explosive subtonic expansion velocities during the Cook-off test. The system enabled a comparison between the results of the two interferometer systems caused by the application of two...

Fiber Optic sensors are found to be very suitable for explosion and shock wave measurements because they are immune to Electromagnetic Interference (EMI). In the past few years, TNO has developed a number of sensor systems for explosion and shock wave measurements in which the optical fiber is a vital component. This paper presents a survey of...

Downwind sound propagation over a noise screen is investigated by numerical computations and scale model experiments in a wind tunnel. For the computations, the parabolic equation method is used, with a range-dependent sound-speed profile based on wind-speed profiles measured in the wind tunnel and wind-speed profiles computed with computational...

For the past years we have developed several optical techniques to measure properties of shock waves. The fibre optic probe (FOP) is developed to measure the shock-wave velocity and/or the detonation velocity inside an explosive. The space resolution can be as small as 0.5 mm. Single fibres are used as velocity pins, and as devices to measure...

Supporting the driver in conducting his nowadays demanding task is a promising means to get the maximum out of the road system with respect to both efficiency and safety. With respect to safety, speed management is a main issue. Police enforcement of speeding is one approach, preventing high speeds another. Intelligent Cruise Control (ICC)...

De STL-standaard, gemeengoed bij rapid prototyping technieken, kan ook een rol spelen in het traject van 3D CAD-ontwerp naar (laser)frezen. Met één druk op de knop de freesmachine aansturen vanuit het CAD-ontwerp komt binnen handbereik. TNO Industrie in Delft hoort op dat gebied wereldwijd tot de koplopers.

Several studies indicate that road users are not able to distinguish roads according to official road categories. As a means of designing a sustainably safe traffic environment the concept of Self-Explaining Roads (SER) has been developed. In order to support safe driving behaviour and appropriate speed choice drivers should be enabled to...
