A subsystem for the management of working hours during the operation of automated technology for the processing of information about scientific activities

This paper considers a subsystem for the management of working hours during the operation of automated technology for processing information about the scientific activities of the VINITI RAS, the goals and tasks of this subsystem, and the methods of their solution, as well as forms of presentation of the results. It describes an automated system for processing the information about the scientific activities of the VINITI RAS as the major source of input data for a system for the management of the work hours of personnel, i.e., a subsystem for gathering statistics and salary estimation for the workers of the VINITI RAS who are employed in the processing of information about scientific activities.     

Mobile geoinformation systems

The geoinformation system for handheld computers (PDAs) makes it possible to solve a wide range of geographically dispersed data (GDD) processing problems. The developed program software (PS) based on effective models and GDD processing methods has allowed significantly increasing the GDD processing rate in PDAs. Yurii G.

Properties of porous tungsten-copper and molybdenum-copper pseudoalloys

Conclusions We obtained a complex of properties (hydraulic resistance, thermal conductivity, heat transfer coefficient) of the pseudoalloys W-Cu and Mo-Cu in the range of porosity 0.49–0.84 for different ratios of the high melting metal and copper. It was experimentally confirmed for the first time that the dependence of the heat transfer coefficient on porosity is extremal. It was shown that Koh's dependence for the calculation of the thermal conductivity of porous powdered metals can also be used for pseudoalloys with the same empirical coeifficient.Translated from Poroshkovaya Metallurgiya, No. 2(290), pp. 47–50, February, 1987.     

Multiple-value inductance coils for working standards

The circuit and construction of new multiple-value toroidal inductance coils of 1 μH to 1 H for first- and second-class working inductance standards are described. Optimal relations between the dimensions of toroidal coils with different cross-section geometries providing the best Q factor for a given inductance and external coil diameter have been obtained. The results of experimental investigations are presented. Translated from Izmeritel'naya Tekhnika, No. 10, pp. 21–24, October, 1997.
