The effect of the die hole configuration in the screw extruder on the pellet quality of the fish formula feed is considered. The results of the corresponding theoretical and experimental research are presented. The surface form of the die hole that allow to produce uniform pressure of the pressable material throughout…
Functions and role of the epistemological optimism, its place in the modern disciplined inquiry are considered in view of ecological safety problems. The impact it produces on the process of building up a contemporary scientific view of the ecological stability on our planet is also described. Basic concepts of the en…
The polemics relative to the applicability of the ‘Dutch disease’ term to the Russian economy is described. The dynamics interdependence of such indicators as oil price, labour productivity, and mineral output is considered. The negative impact of the oil price increase on wages that affects the number of oil workers…
The formulation technique for the asymptotically exact coupling conditions simulating a thin section under the analysis of transverse vibrations of the cantilever fitted rod is presented. The three-piece beam model with constant characteristics in every area is investigated. An exact analytical solution produced from…
A problem on the formulation of the limit set for the sequences of increasing Toeplitz matrices eigenvalues (of the limitary spectrum) with the chosen symbol is solved. The limitary spectrum of the banded Toeplitz matrices is described as a semialgebraic set, viz a solution set of some system of algebraic equations an…
The metal recovery goes from 0,4 up to 0,95 under the machine waste reclamation by the powder metallurgical techniques. Energy costs on the article production decrease. Under separating the slime produced in steel parts grinding, the promising approach is the liquefaction of dispersed ferromagnetic materials in the ma…
The problem of increasing the efficiency of cache systems using artificial intelligence techniques is considered. The formalized statement of raising the cache effectiveness on the basis of the set-theoretic mathematical tools is described. The fuzzy logic application technology for determining the victim which implem…
The results of the gender analysis of the educational process in the engineering university are presented. The gender analysis is made in stages, and it is defined by the well-structured diagram. Within the frame of this research, the gender analysis appears a constituent of the gender strategy of the engineering univ…
At the present stage of the Russian economy development, education in its extricable connection with science and production accommodates the efficiency and competitiveness of the national economy. In consequence of the interaction of the scientific research, design departments of the industrial enterprises and leading…
This article contains information about the availability of trade warehouses, dynamics of regional development defined stages of storage systems, commercial and technological process design, goals and objectives.
Some issues on the mathematical model justification and the solution to the problem of the labour safety risks assessment at the machine building enterprises are considered. As a result, the phases of occupational hazards threat, and the conditions which may result in workers death, injury, or disease, are discovered.…
Rails refer to the intensive sources of the acoustic radiation. In rail traffic, rails to a large extent form an acoustic field at the work places of locomotive crews, and in the adjacent residential area nearby the railway track. A considerable extended line source is taken as a noise source model. Analytical depende…
The short and long term creep behavior is one of the most important properties of polymers used for engineering applications. In order to study this kind of behavior of PP tensile and short term creep measurements were performed and analyzed using long term creep behavior estimating method based on short term tensile…
The development of the conceptual approaches to the justification of the eco-economic imperatives of the sustainable socio-eco-ecological regional system is particularly relevant in the context of the transformation intensification in the modern macroeconomics and the increasing significance of the environmental facto…
Some issues on the quality improvement of the services which are carried out by the engineering centre through the registration of the problem area knowledge in the information resources are considered. The process approach is applied as the basic conception of improving enterprise performance. The processes of the en…
The basic external actions on the grain combine mechatronic control system, and their effect on the motion pattern and the production process are considered. The research objective is the problem solution on the adaptive control of the motion path and tool load ratio of the grain combine based on fuzzy logic inference…
The author considers that a person can possess a psychophysiological proneness to one of the types of the management behaviour: ‘civil service’, ‘entrepreneurship’, ‘business-activity’. The systemization and development of techniques for the identification of personal qualities of leaders at various levels and scopes…
The possibility of the vibrowave impact application under the connecting threads disassembly is investigated. The specified operations go to make up a considerable amount of work in the repair and recycling of engineering products. It is essential to find the problem solution to restrict the environment pollution, to…
The effect of clay-induced morphological transitions on the structure formed in the course of reactively induced phase separation (RIPS) and its impact on the properties of epoxy/polycaprolactone (PCL) nanocomposites were studied. The effect of organophilized montmorillonite on the behavior of epoxy containing 5–30% P…
The problem on the task distribution among the multiple homogeneous computing devices by the minimax criterion is considered. The problem definition with the detailed description of the subject of inquiry and its basics is given. It is proposed to use approximate algorithms for the solution to the problem. Both Krohn’…
