On the basis of linear control equation the inspectability property of determined dynamic systems over finite fields has been offered. Connection between inspectability and fundamental property of controllability of system is established. The synthesis example of the inspectable determined dynamic system over finite field has been constructed.

In the work we study a mathematical model about control of investments distribution, when the technological change is taken into consideration as an increasing elasticity coefficient on the capital factor. There is proposed a solution algorithm to solve respective optimization control problem, where the investment funds are taken from the amount which was earlier intended for investments to the manufacture process. As a result, one can achieve at a final moment of time an additional volume of production, when compared with the one given by real statistical data, as well as to reach a maximum capital accumulation.

The basic stages of a complex development direction of a science and practice of powder metallurgy as method of information-analytical representation of its basic aspects are presented. The basic algorithm of carrying out of operations and the scheme of the decision of tasks in view on object with some number of unknown factors is given. Ways of the further perfection of the presented technology of powder metallurgy and nanocomposite materials are planned.

In this paper we introduce a new objective function for vertical partitioning relations in relational databases. It has been built with the new evaluative criterion: cache hit probability. Also present heuristic algorithm for finding the optimal partitioning schema.

The concept of homogeneous structures which realize principles of generating and expanded programming is introduced. Homogeneous structures are considered as the configuration reference point of the program project defining a process direction of division into modules and program structurization. Same examples of homogeneous structures are described. The place of concept of homogeneous structures among programming paradigms is analysed. Advantages of the homogeneous structures's use are shown.

In this paper the hybrid algorithms in object caching system is considered. The method using hybrid algorithm in implementation of the adaptive caching systems is offered. The new universal method hybridization of two and more caching algorithms is described. The description of the new hybrid (of the algorithm LRU and LFU) algorithm, namely Random Recently/Frequently Used (RRFU) is presented. The result of comparative study of the new algorithm RRFU and well-known hybrid algorithm LRFU is showed.

In present article the approach to calculation and modelling of the stationary and almost stationary magnetic fields, based on transformation of a vortical magnetic field to a potential field is stated. The fact consisting in representation of a contour is put in a basis of a method, formed thin closed токовой by a string, equivalent concerning a magnetic field outside of his double layer of magnetic charges leaning on this contour.

In the given paper equations of motion of a drive of end-effectors of a combine are gained at turning on lenix-transmissions which in this phase exhibits properties of a nonlinear nonholonomic constraint of the second order. It is displayed, that without essential lapses for practice the equation of a nonlinear nonholonomic constraint can be linearized and applied to build-up of analytical model of acceleration of a drive of a combine of equation Tsenov of the second stem.

The defects found in the methods of the ABSAEA on the designation of the energetic parameters of the engine in the conditions of exploitation are represented and analyzed in the article. On the basis of the given analysis the improvements of the methods and devices of investigations of the engines with the turboblower on the acceleration of the crankshaft at the transient regime are offered.

The modeling done under the programme «DISK-REVERSE» allows to build the diagrams of dependence of the basic digital output parameters of the disk from the factors characterizing a place of giving, an angle of an inclination and direction of the disk rotation. The given digital output characteristics for work of the device on a field in calm, with wind protection and on a slope can be received by changing the digital input factors. Reversing disk rotation allows to reduce a range of diapason of the manure guide or the range of regulation of an angle of boards inclination.

Happen to the results of the experimental studies, directed on determination brought three-dementional acerbity sleeve high pressure and hydraulic cylinder from degree of the moving the rod

The methodology of modeling and optimization of vibrating protection systems of a workplace of the operator of a knock-out lattice for branch by a vibrating method of a forming mix in foundry manufacture is considered.

Increasing the accuracy and high acting of positioning for technological machines and their mechanisms is of great importance. It is achieved by inventing and modification of hydro-mechanical devises with hydraulic connecting lines. In this statement the positioning process of such devises is modeling, relationships between velocity of hydraulic motor(executive mechanism), backpressure of brake valve and precise stopping is gained.

The system of theoretical models past experimental check is developed. The given models can be used for increase of efficiency of strengthening processing in fraction at a stage of technological designing
