NUMERICAL SIMULATION OF HEAT TRANSFER PROCESSES IN SOLID STATE THERMOSTATIC SYSTEM Olga Belova, Maria Korneeva, Daria Mustafina

The results of numerical investigation of thermostatic system based on Peltier thermopiles are presented. In order to conduct research in dynamic regime of work the numerical method was developed. This method in-cludes one-dimensional model for quick calculations and three-dimensional more precise model for investigation of temperature fields. This method can be used to solve different types of problems dedicated to upgrading of construction and designing of new devices.

LOCAL NAVIGATION SYSTEM FOR SURFACE MOBILE ROBOTS Черноножкин В. А., Половко С. А.

The local navigation system, a part of navigation complex for surface mobile robots, is presented in this article. Features of mobile robots’ motion are taken into account in this system to solve navigation problems more effectively than when using navigation systems for other types of vehicles.

SIMULATION MODELLING OF MULTINOMENCLATURE MACHINE-BUILDING PRODUCT LINES OPERATION Michael Levin, Artem Denisov, Baranov Alexander Vasilievich

The description of the unit "Grouping" is given in the article responsible for problem solving of designing products technological unification in CAD/CAPP/CAM/CAE system and generalized balancing product lines algorithm is resulted.

USE OF THE WAVELET-ANALYSIS FOR PROFILOGRAM PROCESSING Musalimov Victor M, Denis Ershov, Dmitry Zapatrin, Крылов Н. А., Vitali Lulin

The device for experimental research of friction processes is considered in the article. Dynamic character-istics of friction processes have been compared with microprofilograms, and correlation between them has been established.

PHASE SHIFT METHOD FOR DURABILITY MEASUREMENTS OF FIBER OPTIC CABLES UNDER LONGITUDINAL TENSILE LOAD Musalimov Victor M, Nikita Ovseev

The subject of interest in this article is reliability of fiber optic cables under longitudinal tensile load. The main reliability criterion of optical cable is life time. According to standards it is 25 years. Reasons of durability changing were explored in this work. It is shown that mechanical longitudinal load is practically the main factor that reduces life time of fiber optic cable. Ways of decreasing the level of errors and updating the traditional scheme of the phase shift method are given. The method and installation scheme were realized in a real test bed.

AZIMUTHAL ALIGNMENT OF GYROINKLINOMETERS FOR ARBITRARY ORIENTATION WELLS WITH GPS-COMPASS Yakov Binder, Pervovskiy Vladimir

Various variants of an initial azimuthal alignment of gyroinklinometer from independent gyrocompassing up to external course pointing with application of satellite navigating devices are analyzed. Lacks of existing methods of an initial alignment and an opportunity of their elimination are shown at transition on external course pointing. The opportunity of realization of an initial alignment by means of GPS-compasses is considered and the constructive decision for device bases binding is offered.

PROGRAMMING MOVEMENT OF BIPEDAL WALKING MACHINE IN SAGITTAL PLANE Yuri Kotelnikov, Rostislav Alekseev

The article deals with the comfortable bipedal robot movement with given program paths for pelvis and feet in rectangular coordinates. Analytical calculation of master control for actuator with an application of in-verse kinematics problems solving is given.

TECHNOLOGY

HIGH-VOLTAGE MODULATOR CONSTRUCTION WITH NANOSECOND FRONT FOR THE ELECTRO-OPTICAL SHUTTER MANAGEMENT AS A PART OF THE SOLID-STATE LASER Vyacheslav Togatov, Dmitry Ternovsky

The mode of ultra fast switch-on of the MOSFET at which the device switching time does not exceed nanoseconds is considered. The explanation of the ultra fast switching mechanism is offered. Results of the experiments confirming the ultra fast switching mechanism are presented. Construction possibility of the high-voltage modulator with nanosecond front on the basis of ultra fast switching effect of the MOSFET is considered. Block diagram and characteristics of the developed high-voltage pulse modulator for electro optical shutters management with an impulse amplitude of 6 kV and front time up to 5ns are presented.

PARAMETER IDENTIFICATION OF HEAT FLOW IN 1D- CALORIMETER WITH HEAT-CONDUCTION COEFFICIENT SPECIFICATION Pilipenko Nikolay V., Kirill Kirillov

The article investigates application possibilities of parameter identification method for simultaneous heat flow recovery and heat-conduction coefficient specification of calorimeter material. Mathematical models description and testing results of the designed program are given.

CODE GENERATION SYSTEM THORNADO AND ITS APPLICATION TO BUSINESS-SOFTWARE DEVELOPMENT Dmitry Deyev, Yuri Okulovsky, Vladimir Popov, Victor Chastovskih

We consider the system of generative programming Thornado. It is based on markup languages, script languages and object-oriented programming. The application example of this system in business-software devel-opment is shown. Arrangement of software development with Thornado system is discussed.

MULTI AGENT IDENTIFICATION SYSTEMS WITH SEMANTIC DISTRIBUTION OF THE OBJECT OPERATING MODEL Demin Anatoly V.

Multi agent system architecture of engineering objects identification is considered in the article, and re-searches of multi agent approach application with semantic distribution of the object operating models are given.

APPLICATION OF MDD AND AOP PRINCIPLES TO GRAMMARWARE DEVELOPENT Igor Yu. Popov, Andrey Breslav

Contemporary tools for grammars and grammarware developing do not satisfy the requirements of OO-software engineering: different system aspects are mixed up, modularity and separation of abstraction levels are violated. A concept of a tool aimed to solve these problems using the principles from Model-Driven Develop-ment and Aspect-Oriented Programming is presented in this paper.

FEATURES OF OPEN PRODUCTION DOCUMENTATION PROJECTS ON THE SINGLE BOARD COMPUTER EXAMPLE Gatchin Yuri A, Paul Kosenkov

The given work is devoted to the hardware creation model. The characteristic feature of the model is project documentation availability shown on the open single board computer example. Electronic devices design peculiarities with instant publication of intermediate variants in open type are shown. This feature allows in-creasing quality and decreasing founding and time of electronic device engineering. “Subversion” repository application is considered with integration of an automatic documentation generation program. Such approach gives the possibility to create documentation automatically and at the same time with the project design. This method allows not only to save resources but to promote the project using its openness as a competitive advantage.
