Evaluatie van de YPR-765 rijsimulator en voorstel voor een aangepast leertraject [Evaluation of the update program of the YPR-765 driving simulator and consequences for the training program]

At the Armor Infantry Driving Education Center (PIROC) of the Royal Dutch Army, a new full-scale training simulator for YPR-765 drivers has been installed. Because this simulator showed for many subtasks differences with the same subtasks performed on the operational tracked vehicle, it was expected that the training potentialities would be...

Simulation of hand cooling due to touching cold materials

A simple analytical model has been developed to simulate the cooling of the hands due to touching various types of cold material. The model consisted of a slab of tissue, covered on both sides with skin. The only active mechanism was the skin blood flow. The blood flow was controlled by body core temperature, mean skin temperature, and local...

Evaluatie van de Leopard-2 rijsimulator en voorstel voor een aangepast leertraject

Op grond van een inventarisatie en evaluatie van de resterende tekortkomingen van de Leopard-2 rijsimulator wordt een aangepast leertraject voorgesteld.

Calculation of clothing insulation and vapour resistance

Based on a physical model, in which a human is depicted as a collection of appropriately sized cylinders, clothing insulation and vapour resistance are calculated for standing persons in still air, when the clothing ensemble thickness, total fabric thickness, number of clothing layers and number of trapped air layers are specified for each...

Simulatoren en verkeersoefenterreinen in de militaire rijopleiding; literatuurstudie en advies

Op basis van een onderzoek naar de "state of the art" wordt aangegeven in hoeverre, en op welke manier de militaire opleiding voor chauffeurs van lichte vrachtauto's met behulp van rijsimulatoren en verkeersoefenterreinen kan worden verzorgd.

Proposal for a new performance evaluation and feedback system for the YPR-

Ter vervanging van het falende "Performance and Marking" systeem, bedoeld beoordelen, wordt het ontwerp geleverd voor een nieuw "Performance Evaluation and Feedback" systeem.

Clothing ventilation, vapour resistance and permeability index: Changes dus to posture, movement and wind

Using the trace gas diffusion method, the vapour resistance of three clothing ensembles (two permeable and one impermeable) was determined for four subjects, sitting, standing or walking at 0.3 and 0.9 m/s, combined with three wind speeds of <0.15, 0.7 and 4.1 m/s. Sitting increased vapour resistance by 12-36%, whereas walking and wind decreased...

Resultant clothing insulation: A function of body movement, posture, wind, clothing fit and ensemble thickness

The individual and combined effects of sitting, walking at two speeds and three wind speeds on the insulation value of three clothing ensembles were determined on four subjects (two with loose clothing fit and two with tight clothing fit). Subjects were wrapped in synthetic foil before dressing in order to avoid sweat evaporation and so increase...

De YPR-765 rijsimulator als leerhulpmiddel

Met de YPR-765 rijsimulator zullen, ook na het aanbrengen van de maximaal mogelijke verbeteringen, een aantal taken, zoals terreinrijden en rijden in het verkeer, niet effectief kunnen worden getraind. De leereffectiviteit van de taakonderdelen: bochten, bijzondere verrichtingen en obstakels zal waarschijnlijk kleiner zijn dan bij de Leopard 2...

A basic analysis of cogeneration economics

The economics of small scale gas turbine based cogeneration systems are analyzed on the basis of avoided costs for an electric utility exploiting such systems. This concerns a theoretical study in which the cogeneration system as a means for electricity generation is assumed to supplant the building of new central electricity generating plant....

The actual insulation of multilayer clothing

The effect of geometric factors on insulation was calculated mathematically for standing humans. It was found that internal radiative heat transfer in an ensemble was significant for insulation, that intrinsic clothing insulation is a useful concept only for indoor climates, and that shape plays a minor role. The literature agrees closely on...

Effect of the acquisition enhancing drug piracetam on rat cerebral energy metabolism. Comparison with naftidrofuryl and methamphetamine

The effects of Piracetam, Naftidrofuryl and methamphetamine on several parameters of cerebral energy metabolism have been studied. At variance with some reports in the literature neither Piracetam nor Naftidrofuryl affected the cerebral contents of adenine nucleotides and, accordingly, both substances were without effect on the adenylate energy...
