This article considers the modified digital image sharpness analysis algorithm based on the Sobel operators application. Based on this the optimized autofocus process of complex optical a system has been developed. The possibilities of application of the results to the medico-biological probes processing on modern automated microscopes are discussed.
In this work investigated to refine estimates of the values of gamma-percentile life Tr.γ optic cables. Calculations have shown that, depending on the different applications (Instrument Cluster, temperature, etc.) and parameters (length of the cable, etc.) There is a significant change in the values of gamma percentile life. This allows you to say that there is a need for such calculations in the design of fiber-optic data transmission systems.
This review discusses the collective monograph “Becoming a Professor: Academic Careers, Markets and Power in Five Countries” published by New Literary Observer in Moscow. The authors of this voluminous book pursued two goals at the same time. First, they sought to prepare a guidebook on academic careers in France, the USA, Germany, Great Britain, and Russia for young sociologists who are thinking ahead about their professional pathway. Based on various data sources (interviews, secondary data, autoethnography), they present an institutional history of the formation of academic sociology as a profession and describe the main trajectories in the academic biography of sociologists in five countries. Second, they find differences in institutional and extra-institutional mechanisms of recruitment for sociologists and offer a theoretical explanation. They offer the category of “optical systems” as a cultural framework of university organization used by various external and internal agents with different types of resources and motivation. “Optical systems” become an important source of coping with distrust and the fear of being cheated by “noble swindlers, ” since the dynamics of the academic world are forced by the replacement of the suspicions vocabulary. In this review, we give a brief analysis of the chapters, presenting the advantages and weaknesses. This book discusses several important issues: morals and markets in academia; the impact and work of economic incentives; and the strengths and weaknesses of social networks, academic pathways, and political culture. Because of its provocative statements, incriminating comments, and polemic conclusions, this book is worth reading for all those who are involved in the modern system of higher education and science—academics, civil servants, governors, and of course, various experts.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
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.
