New efficient method is suggested for estimating the domain of phase variables in linear nonautonomous systems; the method is based on involving extremal Lyapunov functions. © 2012 Pleiades Publishing, Ltd.

The analytic model of the dynamics of a robot-manipulator is obtained in the infinitely indefinite dynamic and completely observable exterior medium. The unboundedness property of indefiniteness most exactly accounts for the unpredictability of the real world, in which most of the moving objects of the technical nature have to function, and considerably complicates the problem of modeling because in this case the results of the classical theory of control are inapplicable in full measure. In this work an alternative approach to the modeling is developed on the basis of idempotent mathematics, which differs from the known approaches by the possibility of representing a model in the explicit analytic form. © Pleiades Publishing, Ltd., 2012.

In this article are considered the analysis of the provided techniques of survey of the main characteristics of passenger traffics in the suburban and long-distance directions.An approach to the construction of an automated analysis system of passenger traffic, which is necessary to ensure that controls urban passenger transport at all levels of analytical information on actual volumes and dynamics of passenger traffic on urban and suburban routes. It is necessary to assess the current state of the traffic and determine the needs of the population in the form of services. The system of counting passengers replaces traditional manual methods of examination of passenger traffic. To collect baseline data on the number of incoming and outgoing passengers at stops using modern technology automatically calculate based on the use of non-contact sensors that are installed in the salons of passenger vehicles (buses, trolleybuses, trams). © Research India Publications.

The KRIF library of the neutron-, proton- and gamma-spectra emitted by the nuclei excited up to 500 MeV is presented. The KRIF contains information for about 2000 emitters which are the fragments of the ten targets fission induced by the nucleons with the energies up to 3 GeV. © 2010 Owned by the authors, published by EDP Sciences.

The development of deformations and fracturing in D16AT alloy specimens with central holes was investigated using a combination of the acoustic emission, surface-deformation mapping, and strain-gauging methods. Three characteristic deformation-development stages were selected. Changes in the durations of the characteristic stages obtained from the data of the analysis of all informative parameters indicate that the specific duration gradually increases for the second stage and remains constant for the third stage. It was shown that the staging approach in studies and testing of deformations and fractures is quite informative and mutually complementary in the case of low concentrations of stresses. However, the durations of stages that were revealed on the basis of data from recording of informative parameters may be appreciably different. This is associated with the sensitivity of each method to deformation flaws at each scale level and the sensitivity/resolution of the recording equipment. © Pleiades Publishing, Ltd., 2011.
