Проблема взаимного влияния беспроводных сетей связи в системах автоматизации промышленных предприятий и способ ее решения
Automatic electro-thermal analysis is included into Mentor Graphics PCB Design System. New software tool named TransPower is introduced to couple the electrical (Analog Designer) and thermal (BETAsoft) simulators. The design procedure is fully automated, human errors are eliminated, simulation time is significantly decreased, while accuracy and reliability are increased.
The book is considered a non-existing method to improve the accuracy of modeling in computer aided design of airborne electronic aids (ES). Namely, to clarify the geometrical and physical parameters of the models onboard ES running on the print sites, a method is proposed together two complementary approaches to solving this problem, the physical and mathematical modeling design stage . Moreover, we investigate the physical layout is not only the printhead, and a fragment and, based on a physical model of the fragment identification procedures specified by the geometric and physical parameters of the design, in which an electric, thermal, and mechanical processes. The identified parameters are needed to improve the accuracy of research conducted by an integrated mathematical model of the full-sized printed circuit assemblies ES. Opisyvaemsy method in the book is the development of models of integration of research work carried out at the Moscow State Institute of Electronics and Mathematics (MIEM) in the development of new versions of the automated system to ensure reliability and quality of the equipment ASONIKA. The book is intended for scientists and specialists involved in the creation of ES vysokonadezhnoyh board, as well as graduate students and students engaged in research in this field.
Automated electro-thermal analysis is realized in the last version of Mentor Graphics PCB Design System. The special software tool AETA is developed and integrated into the Expedition Enterprise PCB Design System to automate the process of power-temperature traffic between electrical and thermal simulators. Furthermore AETA provides the graphical user interface and the possibility to use the different versions of Mentor Graphics software.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
