When considering the ergodic problem for gravitating systems of N point masses we have to take into account the circumstance that for large enough N (i.e. for galaxies of the most usual types) the systems are practically collisionless for time scales not exceeding the Hubble time. So it is necessary to follow phase trajectories not only in the 6N-D phase space but in the 6-D phase space. Studying...
This work represents results of verification of experimental samples of Multi-Functional Control Integrated Circuits (MFC IC) developed for modern low power, high-efficiency power supply units. MFC IC samples have been designed and manufactured in 250 nm BCD IC technology that combines CMOS, bipolar and DMOS. Electrostatic Discharge protection solution developed for 2000 V is analyzed.
This work is devoted to the experimental verification “in silicon” of an active output rectifier (AOR) integrated circuit (IC) for high-efficiency power supply units. IC is realized with the use of 250 nm BCD (Bipolar, CMOS, DMOS) mixed technology. As a part of this work, high-voltage low drop output (LDO) voltage regulator integrated circuit (IC) for power supply units has been characterized. This...

This paper presents simple ways of implementing wavelet filters of arbitrary length without any analog-digital conversion and storage devices. Designed wavelet filters are fast, easy to implement, standardized inputs and outputs, and the ability to quickly cascading, restructuring and discrete-analog representation of the results.

We study the design of different majority voters based on a commercial 65 nm CMOS technology, propose the test system and discuss the experimental results of heavy ion irradiation campaign and the proposed relative efficiency criterion for choosing the voter for a given TMR strategy.
We study the design of different SRAM blocks based on a commercial 65 nm CMOS technology and discuss the experimental results for X-ray, proton and heavy ion irradiation campaigns. The results obtained show that the number of affected bits depends not only on LET value, but also on the localization of a strike. DICE cells demonstrate about 2–3 orders of magnitude lower than cross-sections for 6T-cells...
This article represents the results of mathematical modeling of thermocompensation scheme using bipolar junction transistor. Also it represents the result of temperature testing by experimental model in extended temperature range 25–2500C. It was shown that practical realization of this thermocompensation scheme is real for temperature up to 2500C and this method is capable of minimization temperature...
The results on SEE sensitivity of 0.5 µm SOI CMOS microprocessor are presented and discussed. The comparative analysis of different test techniques (particle accelerator, pulsed laser technique and 252Cf fission source) is provided for the cache. The possible sources of discrepancies between test results and the ways of data correction and methods of testing techniques' accuracy improvement are discussed.
The article describes the methodology and practical implementation of Cash Flow at Risk (CFaR) calculation with the help of a multidimensional Monte Carlo simulation. CFar is one of the most important characteristics of liquidity. It assesses the likelihood that operating cash flows will drop below a prespecified level. In this paper is considered application for measuring CFaR under impact of different...
A prototype system has been developed, based on a mobile Smartphone linked via Bluetooth to a range of monitoring devices (pulse oximeter, blood pressure monitor, ECG monitor), with a facility to integrate to clinical information systems, to enable individuals to self manage their own healthcare. The system has been developed to be used in specific chronic disease applications. The research study...
