The paper shows that while improving a system of settlements pertaining to plastic flow a quantitative assessment of turbulence influence may be determined with the help of self-organization criteria arising due to disturbance of  a  structure  symmetry  being  in  a  stressed  and  deformed  state which initiates local changes in the state and permits to bring an additional resistance developing during transition process from a laminar flow to a turbulent one. This change in resistance is determined by rheological dependences, for example, t_max = const = k, and a geometric parameter of obstruction that is an error angle of shift directions during the above-mentioned transition.

The paper considers a methodological approach to an analysis and estimation of information security in the information systems which is based on the analysis of vulnerabilities and an extent of their hazard. By vulnerability hazard it is meant a complexity of its operation as a part of an information system. The required and sufficient vulnerability operational conditions  have  been  determined in the paper. The paper proposes a generalized model for attack realization which is used as a basis for construction of an attack realization model for an operation of a particular vulnerability. A criterion for estimation of information protection in the information systems which is based on the estimation of vulnerability hazard is formulated in the paper. The proposed approach allows to obtain a quantitative estimation of the information system security on the basis of the proposed schemes on realization of typical attacks for the distinguished classes of vulnerabilities.

The methodical approach is used for choosing variants to be applied for realization of protection mechanisms in the information systems as well as for estimation of information safety in the operating information systems.

An analysis of dynamics concerning development of smoothness regression processes is given in the paper. The paper describes the existing methods for evaluation of strength within the framework of modern investigations. Principles of designing non-rigid motor roads are comprehensively studied in the paper. The paper proposes a dependence between pavement strength and pavement smoothness.

 

Accepting a traction efficiency as a criterion of effectiveness an optimum kinematic discrepancy factor  for a 4К4-model tractor with identical or different wheels and also schemes of drive axle gears are determined in the paper.

The target is formulated that by 2012 it is necessary to increase usage of local types of fuel in the energy balance of Belarus up to 25 %. One of the local energy sources is arboreal fuel. Operational experience of the existing small thermal power stations has shown high cost of the obtained fuel. The paper contains an analysis of technical means for making a storage of hog fuel, their operational processes. Methods for reduction of hog fuel cost using logistics are given in the paper. He paper contains recommendations on selection of efficient technical means for making a storage of hog fuel.

The main peculiar feature of an intellectual system orientated to formulation of original scientific hypothesis, non-trivial technical solutions is an initial target ambiguity of creative search. Process concerning creation of new knowledge in such system presuppose chaotic steps directed on hypothesis synthesis and their improvement, cancellation of non-productive searching methods and advancement of new scientific theories. Formation of new knowledge which generally has random character at the initial stage gradually becomes more ordered, motivated to obtain a concrete result due to development of searching process. Both components of the intellectual medium (a human being and a machine) have so to speak an equilibrium in their actions, actively interacting and supplementing each other in the most creative procedures of hypothesis synthesis. Role difference resides in that a computer provides its formal logical and information resource for solution selection, and a researcher is assigned to carry out an additional task that is to take decisions about correctness of scientific hypothesis

An analysis of transportation services’ market state in the Republic is given in the paper. The paper contains a well-reasoned conclusion that there are significant reserves for higher efficiency of transportation activity. In order to use them it is necessary to exert force on searching rational ways for problem solutions including application of logistics methods.

On the basis of an analysis of scientific, reference and encyclopaedic literature, statistical information, and also main documents concerning power engineering policy a composition systemization of «own fuel-energy recourses» and «local fuel-energy recourses» categories in the Republic of Belarus is given in the paper. The paper also contains a structurization of power resources of the mentioned categories in accordance with directions of consumption of fuel-energy resources for generation of heat and electrical energy and usage of fuel-energy resources directly as a fuel.

In order to increase an objectivity of actual and forecasting estimations of efficiency in respect of power resources’ usage  the paper proposes to analyze consumption of every fuel-energy resources’ type/group separately in accordance with basic directions of consumption but not as a part of boiler-oven fuel. Local fuel-energy recourses are to be considered not as end in itself, but only as a part of own fuel-energy recourses of the Republic of Belarus.
