The FEL-TNO Uniform Open Systems Model is based upon the IS0/0SI Basic Reference Model and integrates operating systems, (OSI) networks, equipment and media into one single uniform nodel. Usage of the model stimulates the development of operating systen and network independent applications and puts efforts like POSIX, OSF, X/OPEN in a wider...

Size distributions of giant sea-spray particles (10-100 micrometer diameter) were measured in the North Atlantic with an impaction method, at heights of 0.2, 0.5, 1, 2, 4, 6, and 11 m above instantaneous sea level. The vertical distributions of the particle concentrations show as characteristic features a minimum at 0.5 m at low winds, and at...

The inter-relationship of food and physical performance, food is considered as a conglomerate of nutrients and man is depicted as a kind of organic pudding. This 'machine' concept of human performance in combination with the mysticism surrounding vitamins, has led to the faddish belief that additional vitamins are necessary to improve physical...

Twenty seven male patients, with Type-I diabetes mellitus were studied, all from the Outpatient Clinic of the Department of Internal Medicine, the Free University Hospital, Amsterdam. In comparison with healthy subjects and as regards age, total cholesterol and LDL-cholesterol levels were within normal limits, although HDL-cholesterol and...

For the past few years an accurate X-band SLAR system with digital recording has been available in The Netherlands. The images of this system are corrected to indicate radar backscatter coefficients (gamma) instead of arbitrary greytones. In 1980 a radar measurement campaign was organized in the Flevopolder area. Ground-based measurements were...

In this paper we give a review of measurements through the atmosphere of 94 GHz attenuation, mid-infra-red (3-5 μm) and visible wave transmittances. The relationships between these quantities are given as a function of meteorological parameters. In rainshowers the theoretical predictions, based on Mie scattering theory, are in good agreement...

The renewed application of fast neutrons in clinical radiotherapy has been stimulated by fundamental radiobiological findings. The biological effects of high LET radiation, including fast neutrons, are different from those obtained with X-rays in at least three respects: the oxygen enhancement ratio, the sensitivity of cells at different phases...

Studies on microwave surface scattering in The Netherlands have indicated the need of accurate radar systems for applications in remote sensing. A SLAR system with digital recording was developed and is now being used for several programs. This system was designed with special attention for speckle reduction and system accuracy. The digital data...

Development of microfocus X-ray technique is defined. Advantages on other methods, principle of operation and the material comprising an intense electron source imaged on an X-ray target by means of a double magnetic lense system, are described. Resolution value at 150 kV is the imaging of a 0.1 mm steel wire 10 mm thick wall of a steel cylinder...

Koöperatíeve verschijnselen kunnen optreden in systemen die opgebouwd zíjn uít zeer vele met elkaar wisselwerkende subsystemen. Voor de 'míkroscopische' subsystemen kan men bijvoorbeeld denken aan menselijke individuen, hun hersencellen, of aan atomen. Het samengestelde, 'makroskopische' systeem kan dan respektievelijk de maatschappíj, de...

The merits of the 'vacuum form fixation' are discussed for the production of reliable body impressions of patients suffering from sitting problems. Impressions are taken with the patients seated in the desired posture. The first results are reported, obtained from 4 patients of different categories, fitted with individually moulded seats...

A survey is given of the most common types of coherent optical correlators, which are classified as spatial plane correlators, frequency plane correlators and special reference correlators. Only the spatial plane correlators are dealt with rather thoroughly. Basic principles, some special features, advantages and disadvantages mostly are given...

Protection against the effects of the nuclear electromagnetic pulse. A nuclear explosion generates a short impulsive electromagnetic field which propagates over the earth radially from the point of explosion. In the explosion zone the electric and magnetic fieldstrengths are high and may damage cables and electronic equipment. The phenomenon is...

Gaslasers worden veelvuldig gebruikt bij experimenten, waarbij hoge eisen aan de coherentie-eigenschappen van de lichtbron gesteld worden. Wanneer echter een uitgezonden vermogen van enkele mW noodzakelijk is, dan is werking in meerdere longitudinale modes onvermijdelijk. Het optreden van meerdere longitudinale modes betekent zowel een erstige...

The influence of increasing range resolution on the detectability of targets with dimensions greater than the resolution cell is studied. An N-cell target model is assumed, which contains k reflecting cells, each reflecting independently according to the same Rayleigh amplitude distribution. It will be referred to as the (N,k) target. Detection...

It is shown that MO theory predicts the butadiene molecule to be flat, and that VB theory predicts a skewed configuration of this molecule. The calculations of the resonance energy of conjugated systems, using either VB or MO theory, are discussed and compared. Benzede is taken as an example. Emphasis is laid on the requirement of similarity...
