Diagnostics of Some Defects of the Internal Combustion Engine by a Chronometric Method

It is shown that it is possible to record defects in an internal combustion engine by a chronometric method. The following defects are considered: a reduction in the quantity of injected fuel and the ignition advance angle.     

Classification of single-electron devices

A classification based on the principles identified in this paper is proposed for single-electron devices. A large number of currently known nanoelectronic devices of the type considered here can be described on the basis of this classification. This classification can be used to propose new single-electron devices. Fiz. Tekh. Poluprovodn. 33, 1388–1394 (November 1999)     

Improved identification of squeeze-film damper models for aeroengine vibration analysis

Numerical solution of the Reynolds equation imposes a prohibitive computational cost on the dynamic analysis of practical squeeze film damped turbomachinery. To surmount this problem, the present paper develops the use of Chebyshev polynomial fits to identify finite difference (FD) solution of the incompressible Reynolds equation. The proposed method manipulates the Reynolds equation to allow efficient and accurate identification in the presence of cavitation, the feed-groove, feed-ports, end-plate seals and supply pressure. The ability of Chebyshev polynomials to rapidly reproduce FD routines is demonstrated. The bearing models developed are experimentally proven to give more accurate results than alternative analytical bearing models.     

Influence of heat treatment regimes on the structure and mechanical properties of polyamide composites

We analyze changes in the structural characteristics and mechanical properties of composite materials with a polyamide matrix depending on the type of heat treatment. It is shown that thermocyclic treatment with a decrease of temperature to cryogenic temperatures leads to partial cold recrystallization in nanofilled materials and to an increase in the adhesive strength of glass-filled specimens.
