This handbook presents a set of calculated analytical formulas for determining the basic electrophysical parameters of electronic equipment: electrical capacity, inductance and wave impedance. These parameters play an essential role in ensuring the signal integrity and power integrity of electronic equipment and its electromagnetic compatibility. It is especially important to have design ratios when designing transmission lines on printed circuit boards or in wiring with a given characteristic impedance. It is very important for developers and designers to obtain operational estimates of parameters in the early stages of design, which is possible using this handbook. The analytical expressions provided in it provide accuracy that is acceptable for engineering practice. Each formula in the reference book is accompanied by tables with the results of calculations in a certain range of parameter values, the corresponding graphs and comments that allow you to gain experience in the physical interpretation of the results. For the most cumbersome analytical expressions, alternative compact expressions based on various approximations are proposed. This greatly simplifies the calculation. The reference book is aimed at a wide range of specialists involved in the design of electronic equipment and printed circuit boards; it will be useful for practicing engineers who are engaged in the design of technical equipment
Identification and assessment of the effectiveness of corporate risk management has a special mission to promote the development of science . Different authors demonstrate the variety of appro- aches to the identification and interpretation of efficiency (indirect vs. direct, qualitative vs. quan- titative, economic vs. managerial, etc.), but the role of risk management efficiency as the part of the corporate’ system of management and governance seems to be a commonplace. We have identified a relatively small number of scientific papers devoted to the problem risk management effectiveness. There is no consensus on the definition of the effectiveness of risk management. In the studied appro- aches to the definition there is no unity, as a corporate risk management rather multifaceted. At the same time, it is impossible to consider, for example, the effectiveness of the risk management process in isolation from economic efficiency. This paper is an attempt to fill this gap. The article presents the discussion of approaches to determine the effectiveness of risk management, the results of the syste- matization of the key factors in the effectiveness of risk management. As a conclusion the complex de- finition of risk management efficiency is given, which is based on key parameters of the presented approaches, as well as the basic directions of development of the study area are presented.
The application of mathematical modeling methods (with subsequent computer sales) to determine the parameters of accuracy geometry bands obtained with the new equipment and process the step deformation bands of hard alloys based on copper
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.
