    Springer
    Computing 44 (1990), S. 159-168 
    Details
    ISSN: 1436-5057
    Keywords: reliability control ; computer simulation ; stochastic approximation ; stochastic processes with complete connections

    Topics: Computer Science
    Description / Table of Contents: Zusammenfassung Diese Arbeit hat das Ziel, Simulation einiger stochastischer Prozesse zusammen mit stochastischer Approximation zu benützen, um eine optimale Zeitfolge für die Zuverlässigkeitskontrolle zu bestimmen. Wir zeigen überdies, daß der resultierende stochastische Kontrollplan adaptiv ist.
    Notes: Abstract The aim of this paper is to use the simulation of some stochastic processes combined with the stochastic approximation technique, to determine the optimum sequence of moments of time for the reliability control. It is shown that the obtained stochastic approximation control plan is adaptive.

    Notes: Abstract Cesium atoms, enclosed in a glass vessel, are excited by a weak electrical discharge and irradiated by monochromatic light with wavelengths corresponding to the sharp, diffuse, and fundamental series. By light absorption, highly excited atoms are produced, which are ionized by electron collisions. These ions diffuse into the space charge region of a diode path, compensate partially the space charge, and increase the thermionic diode current. By this method, ionic currents of about 10 ions per sec can be detected. If the wavelength of the incident light is varied continuously, the complete absorption spectrum of excited cesium atoms can be found in the recorded diode current.

    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Instrumental neutron activation analysis (INAA) was applied to investigated a total of 16 samples of raw materials, intermediate and final products involved in metallurgical processes in Romanian Iron and Stell works Sidex Galatzy: iron ores and pellets from different regions of the world, cast iron, slag and steels. A series of chemical elements was determined in the analyzed samples: Al, As, Ce, Co, Cr, Fe, La, Mn, Na, Sc, Sm, V, W. A qualitative discussion regarding the passing of from elements with different chemical affinity for oxygen compared to that of iron, from the raw materials to slag or to finite products is presented.

    Notes: Abstract An inexpensive, tunable, filamentary X-ray generator, based on the bremsstrahlung of a pulsed, high-power-density electron beam cruising along a dielectric fiber is presented. At small scale, it encodes some of the features of an X-ray machine for triggering the energy stored in the long-lived 178Hfm2 nuclear isomer, in particular an optimum coupling to the active medium
