The article is concerned with the method of the vehicles overcoming geometrical obstacles increase ability by means of rational supplied to wheels torque distribution. Mathematical models of overcoming of an geometrical obstacle (on the threshold example) by a single wheel and the all-wheel drive vehicles (4×4) are presented. Dependences for definition of the torque and pushing force on each wheel during each moment of time, demanded for overcoming an obstacle with the accepted height are received. Results of calculations on the received mathematical models are presented. It is shown, that at overcoming geometrical obstacles by the vehicles adaptive regulation of the supplied to wheels torque is required. Application of an “flexible” driveline system on off-road vehicles is proved.
Neuro-fuzzy prediction of the glucose level of patients with insulin-dependent diabetes
# 11, November 2010
S.,A. Chernetsov, I.A. Chuchueva
Optimal doses of artificial insulin depend on a variety of factors. Adjustment of insulin dosages is a sophisticated task and can be far too complex for most patients. In order to simplify the solution to the problem the Continuous Glucose Monitoring System (CGMS) and continuous subcutaneous insulin infusion systems (insulin pumps) were developed.Blood glucose level (BG) control systems based on CGMS and insulin pumps are being actively developed. Algorithmically, these systems consist of two subsystems: the BG forecasting subsystem and the optimal dose determination subsystem. The problem of blood glucose forecasting in type I diabetes patients is being researched here. Artificial neural network (ANN)-based and maximum similarity extrapolation model based on maximum likeness set (EMMLS)-based approaches have been considered. The approach effectiveness has been compared. It is shown here, that neural networks provide more accurate results for short-term forecasting, while EMMLS is more accurate on long-term forecasting. Prospects of combined EMMLS and ANN model are also shown.

D.S. Blinov, V.F. Alyoshin, I.A. Laptev, A.V. Frolov, A.V. Kulish
    Further adoption of the prospective roller screws is complicated because of the difficulties one can find in the process of its production. The most complicated part of a roller screw is its nut’s high-precise threading. This complication gave birth to the idea of the whole subclass of roller screws – the nutless ones. The article represents the two general designs of nutless roller screws and its analysis. Being compared to the common screws, the nutless ones proved to have a number of shortcomings and a number of advantages at the same time. That is why one can easily find some applications for the newly-invented nutless roller screws. The absence of nuts makes the technology of production much more quick, easy and cheap, and thus gives an opportunity to start production in Russia. After the successful adoption of the nutless roller screws, Russian machine-building plants will easily continue with the common ones

V.P. Morozov
 Existence of the oscillatory mechanism of hardening of metal of a welded bath in the form of formation of periodically repeating isotherms of crystallization, is characteristic for different metals and alloys. Periodicity of process of crystallization of metal is connected with fluctuations of speed of crystallization of interphase border at its movement with accelerations both the subsequent delays and a stop.It is established that at influence of heat from an external periodically operating source with frequency to corresponding own frequency of crystallization of metal of a seam conditions of a resonance which promote not only to crushing of cast structure of metal of a seam and HEZ are created, but also causes influence of the growth of mechanism the direction heat.                 The fine-grained structure of welded connection received for the account of efficient control by the oscillatory mechanism of moving of front of crystallization, allows to raise essentially resistibility to formation of hot cracks at the expense of periodic changes of temperature in a germinal zone, overcooling of liquid metal and the subsequent changes of rate of internal shrinkable deformations in a temperature interval of fragility.
