This paper considers the questions of excess voltage pulse electronic filter IC applications in order to protect K1482PhiPi1T telephone lines, ILF3866N subscriber line interface IC and IL145557/67 PCM-CODEC and create subscriber's termination of modern digital automatic telephone stations on their basis
An analytical review of publications reflecting development of ground surveillance radars in civil aviation of Russia is presented. In the paper the basic phases and development directions of surveillance radars engineering are considered
This paper presents the review of investigations of multicavity magnetrons with cold secondary-emission cathode operating over the mm-wave band, side-cathode magnetrons and X-band coaxial magnetrons designed and developed at the A. Ya. Usikov IRE NASU for the period 1955 through 2005 and at Radioastronomical Institute (Rl NASU) for the period 1985 through 2005. The distinctive features of magnetrons...
An opportunity of IOT gain increase more than 12 dB is considered using two-gap input cavity with unequal rf voltages across gaps. A new approach to IOT efficiency increasing is proposed using interaction of the beam with two harmonics in output section (class F). Such a mode allows achieving maximal efficiency up to 74%. Device linearity can be improved provided low-frequency video signal at the...
Main aspects of systems approach to distance learning management are examined, including the selection of distance learning system (DLS) architecture, development of distance learning management software (LMS), and of virtual educational data resources
Complete hardware-software sets for various families of microcontroller engineering which permit to to study the architecture and programming features at the education courses and to construct the manufacture and industrial applications. The main goal of such complexes creation related to the absence of the analogous products on the market
The structure and designing peculiarities of the electronic course on the foundations of communication systems computer aided design are considered. The course includes the theoretical material, the checking questions problems and also the laboratory practical work, which can be used for the distance learning of under- and post-graduate students, and PhD students in the direction "Telecommunications"...
The results of influence of informational technologies on the user's organism are presented in this paper. PC is the source of different emanations and electromagnetic fields, providing negative influences; changing the structure of cells, tissues and processes passing in them. It is established, that working with PC may provoke more than 30 harmful and dangerous factors as well as chronic influence...
The results of influence of the work on the computer to functional condition of visual system and student's psycho physiological indexes are presented. Pernicious influence of this kind of activity on researching indexes are shown
It is suggested to use knowledge transplantation method for students' creative abilities promotion and for solution of complicated scientific-and-engineering problems
The report includes the comparative analysis of existing platforms of the training management used both for remote, and for traditional training with the brief review of their opportunities, advantages and lacks for revealing the optimum decision at a choice of a platform
Isomorphous transformation of fuzzy cognitive maps into the models of decision making preference systems has been developed. Considered in this paper are new possibilities for cognitive system of modelling strategies LtCoS-MoSGt) under the analysis of dynamic fuzzy cognitive maps. System algorithms are illustrated by information strategies simulation
In the article standards and directions of quality assurance in the European Higher Education Area are presented. Quality of education is presented on examples of Poland and France. The independent agency-SAC (State Accreditation Commission) appointed in Poland and National Evaluation Committee CNE (Comite National d'Evaluation) in France directs and evaluates researches, teaching and management of...
Presented in this paper are theoretical and practical basing of students' psychophysiological state monitoring in order to motivating healthy life-style in technical universities
Specific features of the rating system for knowledge assessment have been considered. Possible variants of the rating system have been shown, along with brief characteristics and drawbacks. It is recommended to apply "hard" rating for maximum stimulation of educational process
