A forward-looking system for planning and monitoring metrological support to an organization

The ARM-Uchet computerized system is considered, which is intended for accounting, planning, and monitoring for metrological support to an organization and has been implemented on an IBM PC AT. Schemes are given for the basic modes of operation and for the software suites, as well as the database structure.Translated from Izmeritel'naya Tekhnika, No. 7, pp. 70–71, July, 1994.     

Effect of Inductive and Inductive-Resistive Loads on Widths of Electric Pulses from PZT

The theoretical analysis has demonstrated that the width of a pulse from a detector can be reduced by using an inductive-resistive load. A criterion for selecting parameters of the electric load based on the shape of the frequency characteristic has been suggested. Optimal resonant frequencies and Q-factors for transducers from the TsTSNV-1 ceramics have been determined.

Integrated nonlinear analysis of consolidation of weak clayey bases of large fills

Conclusions 1. In the investigated loams loosely bound water occupies no more than 3% of the total volume of their pores. 2. In fully saturated clayey soil, a "pore pressure peak" is absent after application of the load. On the graph of further dissipation of Δp with respect to the square root of time for △σ/△¹j>1/2 there is a straight portion. 3. An implicit relation has been proposed which satisfactorily describes the viscosity properties of clayey soils over the entire range of their possible compression rates in the stabilized and nonstabilized states. 4. An analysis method was worked out for one-dimensional consolidation of a water-saturated clayey base, which takes into account in an integrated way its bedding, the loading rate, the geometric nonlinearity, and the variability of the soil compressibility, viscosity, and permeability. The analysis was performed numerically and by means of a computer program. Comparison of the analysis results by the program with established and well-known experimental laws as well as with test data for the "Ol’gino" site showed that the proposed analysis method reliably describes the process of one-dimensional consolidation of water-saturated clayey soils.

Simulation-based study of botnets and defense mechanisms against them

To defend oneself against botnet attacks, one must have tools that make it possible to investigate the processes occurring on all stages of the lifecycle of botnets (propagation, control, attack) and possess defense mechanisms that can counteract botnets. A simulation-based approach to the investigation of botnets and the corresponding defense mechanisms is proposed. The simulation is performed using a special software environment developed by the authors. The architecture of this environment and the libraries needed to create models of botnets and defense mechanisms are described. Experimental data demonstrating the capabilities of the simulation environment for studying various stages of the botnet lifecycle and the efficiency of the corresponding defense mechanisms are discussed.
