Improvement of technological process of galvanizing in flowing electrolyte without decrease in its reliability and quality of the received deposit can be carried out by carrying out anode etching of the processed surface directly in the main electrolyte of sedimentation. And, providing such conditions of anode etching at which, the details which are formed on a surface products of reactions easily are removed a channel of electrolyte is possible. For the purpose of identification of extent of influence of technology factors on anode dissolution of the processed surface it is necessary to conduct elektrokhikmichesky researches. The installation including electric was for this purpose developed and made and gidravklichesky speak rapidly. The Elektkrichesky part contains power-supply circuits of an electrolytic cell to the asymmetric variables odnopoluperiodno straightened, dvukhkpoluperiodno straightened by current and straightened by current with the lowered pulsation, and also a chain of heating of working electrolyte. The hydraulic scheme of experimental installation includes: the kisloktostoyky electric pump, pipelines, filters, the device for an electrolytic precipitation of coverings and a bathtub with electrolyte. Electrolyte in a cell moved by means of the electric pump. Giving changed in steps, due to change of diameter of the section through passage of the giving pipeline by means of replaceable inserts. Authors of the device for electrolytic drawing coverings are Zakharov Yu.A. and Spitsyn I.A. (patent No. 2155827). The design allows: to increase the speed of a channel of electrolyte; to carry out activation of the cathode, using energy of a channel of electrolyte; to increase the accuracy of copying of the cathode the activating elements; to use higher density of current and to reduce power consumption of the device. Electrolyte, in the course of sedimentation, was constantly filtered. As filtering material used fiber glass. The filter if necessary it is possible to dismantle and wash out quickly. Such filtering element slightly interferes with a channel of electrolyte, is simple in service, is cheap and quite sufficient. Thus, the offered design of experimental installation allows to conduct necessary researches of process of sedimentation of a zinc electrodeposit for its improvement.

Visualization analysis methods allow researchers to detect features at a glance, identify patterns and anomalies in large volumes of information. Value of medical imaging in health care is increasing, as it improves the efficiency of care and create a more comfortable environment for patients. Innovative imaging technologies allow earlier and more accurately diagnose diseases, treat them more purposefully through more benign methods, and carefully monitor the results of treatment. This paper discusses the use of different imaging techniques of experimental medical data (for example, studies of the physiological characteristics of patients with various forms of asthma) . Novelty of this work is to use an integrated approach to solving the problem of state visualization of biological objects. Results of application of various technologies of visualization of medical data on the example of an assessment of dynamics of a condition of patients by bronchial asthma as a result audiovisual stimulation of a brain are presented.

Nowadays, the main way to improve power density is increasing the junction temperature of semiconductor devices and as a result, increasing the temperature of the heat sink. This results in a lower efficiency due to the high temperature caused by increasing power losses. To solve this problem, it’s possible to develop the heat sink for a specific system, or to optimize existing heat sink profiles. This paper presents an FEM-analysis describing thermal behavior of a bidirectional switch used in a direct matrix converter.

Recently becoming urgent problem of managing distributed processes of production, transmission and consumption of energy. This fact is associated with the emergence of a significant number of generators and the possibility of a primary control on all elements of the grid. In this connection, in proposed three-level distributed power grid management, which includes the upper level of segmentation networks, distributed control average frequency and power level and a lower primary control. The methods of control for each of the above levels, the results of simulation.

In this article the author considers the gasdynamic bearing with the spiral flutes which active zone is formed by two close located firm surfaces, on one of which spiral microflutes are executed. The oblique-angled system of coordinates consisting of logarithmic spirals and circles is entered. For each dyad a flute crossing point values of powers of viscous friction were received and further their main moment of resistance concerning a bearing axis is calculated, expression for the main moment of forces of resistance is found in a smooth layer. In work the algorithm, allowing to calculate the main moment of powers of the viscous friction developing in a lubricant layer of the gasdynamic bearing with spiral flutes is received.

The uncertainty is investigated and regularities of their impact on production systems, taking into account the search management strategies. It is proved, that uncertainty is a parameter that accompanies any productive activity for the period of the projection; due to a number of laws (integrativnost′û, integrity, communication, hierarchical structure, osuŝestvlâemost′û, etc.); is based on two basic scenarios: conservative and innovation Are key factors of uncertainty. (information, bureaucratic, change the value of the currency, sanctions, stagnation and so on) in the development of targeted corrective measures on projected periods.
