TNO Technische Menskunde (author), Kappé, B. (author), Korteling, J.E. (author), van Erp, J.B.F. (author)The images presented in low-cost vehicle simulators and in operator interfaces of Remotely Piloted Vehicles (RPVs) often do not provide enough information for optimal vehicle control and do not elicit sufficient spatial orientation. To improve the effectiveness of these images, the virtual viewing direction can be 'head-slaved', or the display...report 1997

van der Horst, A.R.A. (author)Control of driving speeds offers an important possibility to improve traffic safety on rural 80 km/h roads. An experimental project in Drenthe was aimed at the development and testing of measures that effectively reduce speed without significantly reducing driving comfort up to speeds of 80 km/h. First, some variants of proposed infrastructural...conference paper 1997

Kooi, F.L. (author)New methods to measure information uptake and eye strain have been developed. The speed of information uptake is measured with a reading task that demands quick and accurate eyemovements. Accommodative facility is shown to be a good measure for eye strain. A standard monitor and three types of HMDs were compared on both tasks. The HMDs were (i)...conference paper 1997

Holewijn, M. (author), Kooi, F. (author), Punt, H. (author)To determine the effectiveness of rigid bifocal contact lenses for military personnel, three types of lenses were compared: monovision, concentric bifocal, and diffractive. The subjective comfort, clinical status, and a number of visual functions were tested after 1 week and 4 weeks of daily wear. The diffractive and simultaneous vision lenses...article 1997

TNO Arbeid (author), Commissaris, D.A.C.M. (author)The issues addressed in this thesis concern the control of equilibrium in a bimanual, wholebody lifting task. This task comprises the forward bending of the trunk and the lowering of the whole body to grasp an object with two hands, followed by the lifting of the object to waist or chest level. After a general introduction in chapter 1 a...doctoral thesis 1997

Instituut voor Milieuwetenschappen TNO (author), Wyers, G.P. (author), Duyzer, J.H. (author)Dry deposition fluxes of sulphate and nitrate have been determined over a coniferous canopy using the aerodynamic gradient technique. Vertical concentration gradients of sulphate and nitrate were measured with filters; the gradient of ammonium bisulphate was measured with thermodenuders. Filter measurements of sulphate yielded a deposition...article 1997

(author)Background: in 1990, a national survey on adolescent sexuality showed that Turkish/Moroccan students were at special risk for sexually transmitted diseases. In 1995 the study was repeated. This article describes trends in the safe sex knowledge and sexual behaviour of Turkish/Moroccan students. The results are also seen in relation to those of...article 1997

Deze wijze van optreden stond ook wel bekend als attritie-oorlogvoering waarin getracht werd de vijandelijke eenheden tijdens het gevecht meer te laten 'slijten' dan de eigen eenheden.

TNO Technische Menskunde (author), Daanen, H.A.M. (author)When human fingers are exposed to cold, the blood vessels in the skin contract. Thus an insulation layer is constructed that retains the body heat. This, however, can lead to problems in the fingers: the cold reduces the mobility and sensitivity of the fingers, thus increasing the risk for cold injuries and decreasing the manual dexterity....doctoral thesis 1997
