The processes of information support of situational management of infocommunication networks in the conditions of influence of external disturbances are considered in the work. The expediency of using the mathematical apparatus of information theory for the analysis of processes of control of parameters of infocommunication networks is substantiated. It is shown that periodic multiple sequential control of the parameters of the infocommunication network provides determination of the state of the network under the influence of external interference and the probability of its transition to a new state in the near future. The entropy of the controlled process changes with changing quantization step and multiple successive measurements. It is noted that in the case of periodic multiple consecutive control, the object is constantly in transition in terms of information. The entropy value of an object can be considered determined only for some short periods of time between measurements or when information about the object is not received. An important condition for improving the quality of control is to reduce and completely eliminate delays in the information process.

AbstractDensity measurements of plutonium metal and its alloys are performed at Los Alamos National Laboratory (LANL) using a technique based on the Archimedes principle. The goal is to find and characterize a fluid for density determination of large objects made of plutonium to replace the currently used monobromobenzene. Physical and chemical properties must be considered while selecting the fluid. Chemical properties of the fluid must ensure low corrosion rates and good resistance to radiological decomposition. The study was carried on to evaluate the corrosion rates of Pu metal cause by FC-43 and the FC-43 decomposition products of radiolysis. The results of these studies proved favourable for this application. The evaluation of the surface reactions between FC-43 and Pu metal will be conducted in the near future.

(GE/m**3). According to this definition one odour unit is the amount of odorants in one cubic meter of air at odour thres­ hold level. The new definition is a real concentration and gives a better form of input parameter for dispersion models. On the basis of guideline VDI 3881 parts 1, 2, and 3 ringtests were carried out with different odorants. The results can be summerized as follows: -The dispersion of results varies and depends on the compo­ sition of the participants and on problems of sampling and preparation of odorous sample. Lower dispersion is obtained when results with obvious errors in application of guide­ lines or with large deviations from mean value are excluded. -Participants of the Netherlands get systematically lower threshold values than the others. The reason has to be investigated. -All findings of the ringtests lead to the conclusion that it is possible to determine odour thresholds which do not differ by more than factor 10. At present another ringtest is in preparation. This test will be carried out in summer 1985. The French collegues will also participate in this test. Experience of all ringtests will be reported in part 4 of guideline VDI 3881. Guideline VDI 3882 deals with the determination of odour intensity and hedonic tone. The members of the working group "odorous substances" assume that odour threshold and odour concentration are insufficient for the characterization of odorous perception. They recommend to judge the odour inten­ sity and the hedonic tone by category estimation. Moreover, it is their opinion that the odour determination with olfacto­ meters is not suitable to assess odour in ambient air. There­ fore they are preparing two guidelines dealing with these problems. Guideline VDI 3883 gives instructions on the regis­ tration of nuisance by interviews with nearby residents of emitting plants or inhabitants of industrial areas. Addition­ ally guideline VDI 3940 describes the determination of odour in ambient air by inspection panels based on the following idea: During constant conditions as to the class of weather, wind speed, and wind direction each local point is charac­ terized by a frequency of odour perception representing the probability to perceive an odour. The situation at a local point will be have to determine the portion of a year with a frequency of odorous perception greater than 5 % in a random test. Both guidelines, VDI 3882 and 3940, should give corres­ ponding results. Guideline VDI 3781 part 5 completes the complex of odour determination and judgement with the calculation of disper­ sion models. The calculation methode and odour determination by panelists should give comparable results. The following summery can be given. Odour measurements with olfactometers is only a small part of the whole field of odour determination in ambient air and the measurement of odour nuisance must be approached in the near future with appropriate urgency.

The variations of solar irradiance can only be measured with a reasonable precision from space for almost all wavelengths. Yet the history of solar irradiance determinations is, with few exceptions, the history of efforts to patch the infrequent or too discontinuous space-based measurements by devising mechanisms for proxy determination of solar irradiance fluxes from ground-based obtained parameters. Although it appears that in the near future the situation will not be too different, there is some increase in the coverage of the spectral range that will be monitored. From gamma-rays to infrared light there are instruments that are now operating (e.g. GOES, Yohkoh, UARS) or are planned to operate in approved space missions (e.g. SOHO, ATLAS), or form part of proposed, not yet approved, missions. New techniques are being developed specifically for the measurement of solar irradiance variations with increased precision (e.g. cryogenic radiometer) in the next generation of space-borne measurements.

Changes in management of the heat-supplying organizations of the modern city determined by development of technologies in this sphere are considered in the article. Three groups of technologies are allocated, the priority of the auxiliary technologies considered is given. The author points out that there is the need of the information support of management of the heating systems management in the city, which need fundamental reconsideration and radical redesign. The additional argument of the need of reengineering of the heat supplying organizations management is the consideration of the results of their activity, connected with considerable thermal losses. The key provisions of the offered measures for reengineering, based on the creation of processes of information support of management "from scratch" are described. Negative changes of the performance of the heating systems of concrete types were estimated q, and thanks to that the new integrated approach to the choice of methods and technical means of diagnostics of engineering systems and analytical dependences of determination of terms of repair were offered. Obtaining of qualitatively new information through reengineering measures for making managerial decisions is considered. Scenarios of prospects of energy industry, which have been differentiated as the most realistic or connected with the risk of increase in the stubborn problems, minimized by reengineering, were analyzed.

Strain Model

It is standard practice to approximate the post-yield behavior of pipeline steels by means of the Ramberg-Osgood equation. However, the Ramberg-Osgood equation is often unable to accurately describe the stress-strain behavior of contemporary pipeline steels with a high Y/T ratio. This is due to the occurrence of two distinct, independent stages of strain hardening. To address this problem, the authors recently developed a new ‘UGent’ stress-strain model which provides a better description of those steels. This paper elaborates a methodology to estimate suited parameter values for the UGent model, starting from a set of tensile characteristics. Using the proposed methodology, good approximations have been obtained for a preliminary series of eight investigated stress-strain curves. Next to all common tensile characteristics, the 1% proof stress is needed. The authors therefore encourage the future acquisition of this stress level during tensile tests. Currently, the authors perform a further in-depth validation which will be reported in the near future.

Introduction. The peculiarities of the functioning of non-profit organizations in Ukraine are identified. The accounting and information support of the analysis of the activity of public sector entities is considered. It is established that the reformation of accounting of public sector entities related to the introduction of the NP (C) BODS from January 1, 2017 requires a comprehensive analysis of the activities of budgetary institutions. It is noted that the analysis of the activity of a budgetary institution will provide full information about the real economic situation of the organization, reveal unused agricultural reserves for further development and ensure more efficient use of targeted state allocations. The object of research is the Main Department of Statistics in the Dnipropetrovsk region. The priori analysis of dynamic changes in cash inflows by type of income is carried out. It is proven that the use of only absolute indicators to estimate the dynamics of revenues is inappropriate. It is noted that the increase in the dynamics of cash inflows to a budgetary institution can testify only to the impact of inflationary processes. It is proposed to analyse the results of the organization's activities in a phased manner: analysis of dynamics and structure; analysis of the actual expenditures of the organization; assessment of the financial performance and determination of the size of the deficit or cash surplus. The algorithm of the complex analysis of the receipts of funds, incomes and expenditures of the budgetary institution is developed. It is established that the analysis of incomes and expenditures and financial results of a budget institution's activity is a necessary component of effective management of a public sector entity. Purpose. The article aims to evaluate the accounting and information support of the analysis of the activities of the public sector entities and to develop the stages of the analysis of the activity of the budget institution of the Main Department of Statistics in the Dnipropetrovsk region. Method (methodology). Method of system analysis, methods of causal analysis, table and graphical methods, dynamic series have been used in this research. Results. The theoretical synthesis and practical recommendations on the methodological aspects of the activities of non-profit organizations through the analysis of dynamics and the structure of cash flow; actual expenses of the organization; assessment of financial performance and determination of the size of the deficit or cash surplus have become the result of the research.

Abstract. The paper considers two directions in the use of visual data for information support of purposeful movements of ground vehicles. This is optical odometry and navigation by landmarks in the environment. Optical odometry builds the trajectory of movement of the vehicle based on the determination of displacements based on selective visual data from different fields of view. The choice and indication of landmarks at the described stage of research remains with the operator. The vision system (VS) monitors the specified landmarks and determines the position of the vehicle relative to them. The experiments used such fields of view as monocular forward looking, panoramic (fisheye type) and forward looking stereo system. When combining the data of the visual channel with each other and with the data of other navigation systems, the specificity of visual sensors is taken into account – a significant effect of the reliability and accuracy of the results from the observation conditions. Experimental verification of the VS layout showed the achievability of high accuracy in solving the navigation problem using the visual channel. All the components of the described process of organizing purposeful movements based on the use of the visual channel continue to be improved.
