We consider a class of complex systems, such as socio-technical systems on the example of the elemental sulfur producing by Claus process. Its operation takes place in different types of uncertainty and requires the development of specific approaches to the analysis and evaluation of many factors that affect the system operation and aren't giving in to the quantitative and qualitative description. The paper formulates the problem of multifactor risk analysis of emergency situations at hazardous production facilities using the methods of system analysis. The main groups of factors, parameters, and communication of human operator with the technical subsystem are identified. A method is proposed for assessing the level of selected factors influence on the emergency situations risk in system. Introduced the terminological basis for constructing patterns of socio-technical systems state indicators. According to the expert survey an example of the impact assessment diagram of each parameter to the "weight" of one of the indicators was made.

Discusses the use of complicated UWB signals in supergrades and subsurface radiolocation. The aim of this work is to analyze the possibility of complex UWB signals using a simpler aproximarse signals, which greatly simplifies the task of finding the basic parameters of the echo signal. As a model of the complex signal of the selected signal with linear frequency modulation. Designed the error of approximation of ultra-wideband LFM echo signal of the echo signal with a rectangular spectrum with different environment settings and the coefficients of the high bandwidth. Based on these data it is concluded that at high modulation indices it is possible to replace the analytical calculations of complex expressions for the spectrum of the chirp signal by a simple ratio aproximarse spectrum.

Zinc electrodeposits gained the distribution generally thanks to high protective properties. However it is possible to apply zinc electroplated coatings and at restoration of worn-out surfaces of details of cars. Thus zinc electrodeposits possess the high durability of coupling with a substrate that is pledge of long-term service of the details restored by zinc. Ensuring high durability of coupling of zinc electroplated coating with a basis possibly only at careful observance of technological process of preliminary preparation of a surface for sedimentation and directly the sedimentation. Some researchers suggest to estimate the received durability of coupling of a covering with a basis from the point of view of the theory of reliability. Technological reliability of process of preparation of details for galvanizing is meant as percent of the restored details, with a high durability of coupling. Process of preparation represents technical system in which operations act as elements. Reliability of technical system are defined by quantity and reliability of elements, their functional communication. And reliability of elements, is defined by technology factors and depends on quality of carrying out the previous operation. Refusal of any of elements causes refusal of all technical system. That is communication between elements of system consecutive and it is possible to apply the second theorem of probabilities according to which the probability of joint emergence of several dependent events is equal to work of probability of one of them on conditional probabilities of all others to it. It is necessary to understand change of reliability of an element in time as stability of reliability. For the purpose of improvement of technological process of galvanizing it is possible to perform operation of anode etching directly in galvanizing electrolyte. Thus the block diagram of preparation of a detail can be submitted as follows: machining; degreasing of surfaces of a detail Vienna lime; washing in cold water; anode etching galvanizing electrolyte; removal of products of etching from the covered surfaces and an exit to the mode; galvanizing.
