Presents the results of the task orientation of the rotating moving objects based on the use of the developed algorithms for the processing of complex information obtained from triaxial blocks magnetometers, gyroscopes, accelerometers and timer.The proposed scheme miniature orientation system rotating moving objects, implemented as a microprocessor-based measuring and computing circuit board.

Risk Reducing of Information Leakage Due to Compromising Emanation A. N. Anishchenko, A. V. Lyashenko, P. A. Solopov, L. S. Sotov

The results of wide band electromagnetic emission produced by computer are ex-plained. The measurements are done from 20 MHz to 1000 MHz. We found out what parts produce maximum emission, and suggest а method to minimize risk of leakage from uninten-tional electromagnetic emanations produced by computer on personal work place. It is shown that good practice is to fast encrypt of data transmitting by long wires.

The Design and Implementation of the Advanced Bit Manipulation Microprocessor ORBM Based on the OpenRisc1200 Architecture S. I. Nazarov, A. V. Lyashenko, L. S. Sotov, A. L. Khvalin

The design and implementation of the advanced bit manipulation microprocessor ORBM based on the OpenRisc1200 architecture is presented. ORBM is a 32 bit processor based on the ORBIS32 instruction set. The microprocessor performance is increased from two to ten times because microprocessor can execute special instructions of bit manipulation. The first prototypes were designed on the Xilinx XC6LX45 FPGA.

About the Problem of Convergence of the Series of the Perturbation Theory in the Quasipotential Method S. V. Churochkina

The questions connected to the problem of convergence of the series of the perturbation theory in quasipotential approach are considered. The mass ratio corrections obtained recently are discussed and systematized.
