The main trends of updated automobile construction are the use of permanent for lowering mass overall dimension characteristics of electric equipment and an automobile as a whole. Diamond-abrasive treatment of sintered powder permanent magnets on the basis of Barium ferrite, strontium and cobalt is connected with difficulties of obtaining surfaces with little meanings of rouhness due to the higher brittleness, tendecy to crack formation, water-soluble technological lubricants (FWSTL) РВ-6 have been developed which contain fractal clusters and generate in contact diamond-abrasive tooltreated powder magnetic material of films with high load and lubricating abilities. Estimation criteria of water-soluble lubricacants efficiency (WSTL) at diamond-abrasive treatment by friction machine СМЦ-2 have been suggested. Comparative tests on the suggested criteria of efficiency FWSTL РВ- 6 and Lubricating cooland (LC) Blasokut 4000 SF 004 at treating by a diamond disk 2720-0031 ГОСТ 16167-90 of Barim ferrite 16Ба190 have been made. A conclusion has been drawn that РВ-6 possesses high efficiency.

To achieve high accuracy of measurement of liquid flow rate using the hot-wire gauges are encouraged to use multi-segment method of spatial characteristics of the transformation. The method is based on the nonlinear three-dimensional elements. Model the spatial characteristics of the transformation is maximally adapted to the peculiarities of the conversion function of the primary transmitter. Model repeats its spatial form with the non-linearity, zero drift, the influence of external factors, including temperature. This provides a low error rate calculation of flow. Study of the effectiveness of the method was based on experimental data obtained during the calibration at different temperatures. Maximum reduced measurement error does not exceed ~ 0.45% at an arbitrary temperature, recorded during measurement.

This paper offers an improvement for machine vision based tracking algorithm using NARX neural network. This is achieved by predicting the next position of a mobile agent based on previous movement described by time-series functions. The algorithm remains passive and does not interfere with the quadrotr flight path until detection of multiple agent-candidates, when the tracking algorithm is not able to identify or locate the assigned agent. Meanwhile the NARX training set are updated in parallel with each successful tracking cycle. This process is done to eliminate the overfitting problem of BPTT training.

Today’s trend of electronics complicating makes developers to create more complex devices in a shorter time. Developers have to contrive different ways of designing automatization to prevent production worsening. However, automatization cannot improve the situation when an innovative device is developing because such developing involves a lot of testing and researches. In this article authors propose to use hardware in the loop simulation methods to optimize designing process. Hardware in the loop simulation is division the device in functional blocks, some of them are produced as models and other are produced as hardware. Usage of this method decrease cost of modernization hardware blocks and allow using a number of data processing algorithms at the same time.

This article describes the model of the pseudorandom sequences (PRS) generator developed in OrCAD program suite.The described model is applicable for radio systems modules circuits simulation that are using in the operation a PRS. The PRS generator implementation in OrCAD make possible to change PRS parametres immediately in the program, without using other software. A model specificity is that it is parametrised. Parametrization facilitates model control and that is reduce to a minimum necessary manipulations for changing of PRS type. The model is constructed on the basis of circuitry implementation of the linear feedback shift register (LFSR). For adjustment of model it is enough to instal code words setting starting state a LFSR, parametres of a signal of a clock source and to specify register tap output.
