    Notes: Abstract Student movements in Japan have, during the 1970s, tended to move from cooperation between various radical sects to bloody conflict among them, from participation by students generally to involvement by only a limited core of committed activists and from a struggle against the universityand society to one against society alone. The end of the war in Vietnam, the economic crisis, and other societal factors have contributed to these changes. The future of the student movement in Japan cannot be accurately predicted but it is unlikely that a powerful and politically effective movement, such as that of the 1960s, will re-emerge in the near future.

    Scientific objectives of the Monsoon Experiment (MONEX) (1979)

    Notes: Abstract The Monsoon Experiment is the core of the GARP Monsoon Subprogramme, which is a major international effort to achieve a better understanding of the Planetary monsoon circulation, the major seasonal perturbation of the general circulation of the atmosphere and the influence of the annual cycle of precipitation associated with the monsoon on the agriculture of the many populous nations of the region. This is a summary report of the International MONEX Planning Meetings, which were held in Yerevan, USSR, March 1973; Singapore, November 1974; New Delhi, March 1977; and Kuala Lumpur, February 1978. MONEX represents a group of observational studies during the First GARP Global Experiment (FGGE) over the South China Sea (December 1978), Arabian Sea (May–June 1979), and Bay of Bengal (July–August 1979). These periods will permit study of most of the significant aspects of the winter and summer monsoons. This is elaborated on in Sections 2 and 3.

    Preparation of siloxane-like films by glow discharge polymerization (1984)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Glow discharge polymerizations of tetramethoxysilane (TMOS), tetramethylsilane/oxygen mixture (½ molar ratio) (TMS/O2), hexamethyldisiloxane (HMDSO), and tetramethyldisiloxane (TMDSO) were carried out for the preparation of thin, polymeric films with siloxane structures. The chemical composition of the formed polymers was examined by elemental analysis, infrared spectroscopy, and electron spectroscopy for chemical analysis (ESCA) in connection with polymerization conditions, especially, a level of the radiofrequency (rf) input power per mass of the monomers (W/FM value). The polymers prepared from HMDSO at fairly low W/FM values resembled in chemical composition the conventionally polymerized polydimethylsiloxane. The surface properties of the formed polymers also were evaluated by the measurement of surface energy.

    Description / Table of Contents: Zusammenfassung Das Branch-and-Bound-Prinzip kann erfolgreich zur Lösung verschiedener kombinatorischer Optimierungsprobleme eingesetzt werden. In der Regel nimmt der Rechenaufwand jedoch sehr stark mit wachsender Problemgröße zu. Um dieser Schwierigkeit zu begegnen, werden folgende drei suboptimale Methoden oft in der Praxis angewendet: (1) Seien z der Zielfunktionswert der besten bekannten Lösung eines gegebenen Minimierungsproblems undg (P i ) eine untere Schranke für die Zielfunktion des Teilproblems Pi. Dann terminiereP i , fallsg (P i ) ⩾z−∃ (z) ist, wobei∃ (z) eine vorgegebene Fehlerschranke ist. (2) Beende die Rechnung, sobald T0 Teilprobleme bearbeitet worden sind, wobei T0 vorgegeben ist (Beschränkung der Rechenzeit). (3) Berücksichtige stets höchstensM 0 (eine vorgegebene Zahl) aktive Teilprobleme. Die übrigen Teilprobleme weiden ignoriert (Beschränkung des Speicherplatzes). Die Auswirkungen dieser drei Methoden auf die benötigte Rechenzeit und die erhaltenen suboptimalen Lösungen werden theoretisch und an Hand von Simulationen untersucht.
    Notes: Abstract The branch-and-bound principle is successful in solving various combinatorial optimization problems. In general, however, the computation time becomes excessive as the sizes of problems grow. To overcome this difficulty the following three suboptimal methods are often employed in practice. (1) Letz be the value of currently known best solution of a given minimization problem, and letg (P i ) be a lower bound on the objective value of partial problemP i . TerminateP i ifg (P i ) ⩾z−∃ (z), where∃ (z) is an allowance specified in advance. (2) Cut off the computation as soon as T0 partial problems are decomposed, where T0 is a prespecified positive integer. (3) Always take into account at mostM 0 (a given positive integer) number of active partial problems. The overflown partial problems are simply ignored. The effects of these methods on the computation time and the quality of obtained suboptimal solutions are investigated from both theoretical and simulation points of view.
