We consider the optimal control problem for logic-dynamical systems whose dynamical part is given by linear differential equations and whose logic part is defined by linear finite difference equations modeling the automaton with memory. The quality of the control is determined by a quadratic objective functional. This setting is analogous to the classical Letov-Calman problem of analytic construction of optimal regulator. The equations on the synthesis function and on feedback optimal control are derived. We show that the optimal control of the dynamical part is provided by a linear regulator (similarly to the classical case), and optimal control of the logical part is determined by recurrent equation. We describe several examples of these optimal processes including those which require countable set of switches of the logical part.

The results of numerical simulation for ideal gas flow in disk Hartman's generator are presented. It is carried out research of influence of depth of the resonator on amplitude and frequency characteristics. Results received at numerical simulation gas flow were compared with the results received in acoustic linear approach.

Article is dedicated to generalization of ghost-cell immersed boundary method for solving problems of computational aerohydrodynamics in complex geometrical domains, using rectangular grids. High efficiency of this method is demonstrated on a benchmark problem of supersonic flow over the circular cylinder. Comparative analysis has shown good agreement of obtained results with benchmark solutions.

The aid of the article is to compare complexity of deductive (DDRS) and inductive (IDRS) deduce rules' system when constructing formal systems. While using the rule "if q, then P" (DDRS) the construction of formal system is at least accomplished with the help of polynomial algorithms. So the main feature of the programming development now is the constant increase of software cost as far as the complexity of tasks increases. The IDRS (rule "P, if q") does not demand the knowledge of the information transmission addresses and there are no repeated deduce rules. The comparison of DDRS and IDRS permits to conclude: DDRS is more complex in sum then IDRS and does not provide simple linear regulating of algorithm's operators while constructing a formal system. Besides IDRS allows to formalize the process of algorithm's construction in linear mode.

The main task of TV is the finding of ways of such transformation of the image of object so that it was possible to transfer the image methods of telecommunication, but thus it is necessary to achieve that the image created by the reception television device, corresponded to object of transfer as more as possible precisely. An object of research is the principle which is used at construction of system of transfer of mosaic videoimages without use of developing transformations. Studying of construction of the flat optical image not by means of each element, and all elements of the image at once.
