New quasi – 3D numerical model for electrical and thermal analysis of microelectronic semiconductor devices is presented. The general 3D heat transfer and electrical field problems are correctly transformed to the set of 2D equations for temperature and electrical potential distributions in different layers of the device. The complexity and CPU time of the electro-thermal analysis are many times reduced. The results of different devices electro-thermal modeling for different types of semiconductor devices and ICs are presented.
Main concepts and models of the modern theory of self-organization of complex systems, called also synergetics, are generalized and formulated in the book as principles of a synergetic world view. They are under discussion in the context of philosophical studies of holism, teleology, evolutionism as well as of gestalt-psychology; they are compared with some images from the history of human culture. The original and unfamiliar (to the Western readers) research results of the Moscow synergetic school which has its center at the Keldysh Institute of Applied Mathematics of the Russian Academy of Sciences are expounded in the book. Complicated and paradoxical concepts of synergetics (structure-attractors, bifurcations, blow-up regimes, non-stationary dissipative structures of self-organization, fractals, non-linearity) are translated into an intelligible language and vividly illustrated by materials and examples from various fields of knowledge, starting with the laser thermonuclear fusion and concluding with mysterious phenomena of human psychology and creativity. The style of writing is close to that of popular-science literature. That's why the book might be of interest and is quite comprehensible for students and specialists in the humanities. It is shown that the development of synergetics entails deep changes in the conceptual net through which we comprehend the world. It means a radical shift of paradigm, a conceptual transition from being to becoming, from stability to sustainability, from images of order to chaos generating new ordered evolving structures, from self-maintaining systems to fast evolution through a nonlinear positive feedback, from evolution to co-evolution, reciprocal evolution of different complex systems. The new synergetic way of thinking is evolutionary, nonlinear and holistic. This is a modern stage of development within the traditions of cybernetics and system-structural analysis. However, many elements of the latter have undergone important changes since their appearance.
Some texts written by me together with corresponding member of the Russian Academy of science Sergei P. Kurdyumov (1928-2004) and under his direct ideological influence are collected in the book. These texts are elaborated, systematized, brought together in the book and supplemented with new materials. Sergei P. Kurdyumov were possessed of a deep metaphysical flair and put forward ideas, the matter of which are not fully clear up to now. These are, first of all, the idea of co-evolution and the notion of complex structures developing at different tempos as co-existing tempo-worlds. Owing to developments in the field of nonlinear dynamics and of synergetics, the classical problem of time and the problems of evolutionary holism disclose some new and non-traditional aspects. The matter of new notions of nonlinearity of the course of time in the processes of evolution and coevolution and of nonlinear links between different modi of time – between the past, the present and the future - come to the light in the book. Analyses of four interconnected aspects of the course of processes in open and nonlinear dissipative systems – of evolutionarity, temporality, emergent nature and holism – are carried out. A whole series of paradoxical notions, such as “the influence of the future upon the present”, “the possibility of touch of a remote future in praesenti”, irreversibility and elements of reversibility of the course of time appear in synergetics, non-traditional and nonlinear notion of time being at the heart of all of them. It is shown that the best pictorial view of the nonlinear time is apparently the tree of evolution or the tree of time that represent one of archetypes in the human psyche. This image is widely used in myths and religious doctrines of the world nations (the tree of evolution of languages from some united parent language or the tree of evolution of biological species), the image is often drawn by children, appears in consciousness of a man in his sleep, etc. The synergetics methodology under development is applied to study of cognitive systems. The emergent structures of evolution and of self-organization of the individual consciousness, their spatiotemporal peculiarities, and the complexity of the human Self are considered in detail. The radical changes in the understanding of the problems of time that occur due to synergetics are compared with images of time and with the notions of connection between the past, the present and the future in the history of philosophy and of culture. The obtained methodological inferences are of great importance for a reform of systems of education, for forecasting (for building of scenarios of future development), for effective management activity in the modern globalizing world, for elaboration of methods of stimulation of the creative thinking, for the growth of personality and its adequate building into the social media.
Some methodological foundations for elaboration of the modern strategies of ecological thinking based on the theoretical biology and on the theory of complex adaptive systems статье are under review in the article. Ecology, being a science of interaction of living organisms and their communities with environment, goes far beyond its primary frames of the biological knowledge and becomes a nodal discipline from which vectors of perspective interdisciplinary synthesis of knowledge diverge. The ecological approach turns to be fruitful in social and humanitarian researches. Ecology of action, ecology of mind, ecology of life, of cognition and of creativity, ecology of thoughts and words, ecology of ideas, ecology of communication and ecology of management – all these conceptual attitudes give evidence of audacious integration of the ecological thinking in wide spheres of the humanitarian and social knowledge, where it gives opportunities for some fresh approaches. The concept of Umwelt coined by Jakob von Uexküll in 1909 and his study of Umwelt (Umweltslehre) are of great significance for the development of the modern ecological universalism and for elaboration of strategic imperatives of the ecological thinking. The concept of Umwelt as a specific environment to which any biological species or its separate individual is adapted and which is constructed by it allows us to elaborate a real interdisciplinary platform for development of the theory of ecology, for holding a reasonable position in discussions about sustainable development and sustainable futures as well as about the role of education for sustainable development of the world.
The global evolution of the world community as an integrated self-organizing and self-developing system is studied in the article; and some main features and laws of its evolution are exposed. The attention is focused on the consideration of cyclic character of evolution, of periods of the global history of mankind, of the growth of complexity and the birth of technological, social and cultural innovation as a result of passing through crises. This is an interdisciplinary research which relies upon the results of mathematical modeling. The models elaborated by Ivan M. Diakonov, Sergey P. Kapitsa, M. Kremer, Sergey P. Kurdyumov as well as the model of macroevolution of World-System developed by L.E. Grinin, A.V. Korotaev and S.Yu. Malkov are analyzed. The evolution of the world commonwealth is considered as a stage of the universal (global) evolutionary process starting from Big Bang and up to emergence of life, appearance of a human being. The development of World-System in a blow-up regime leads to the strongest stratification of society, to the strengthening of instability and unevenness of development of countries and territories, to disintegration of complex geopolitical structures, and to the threat of collapse of civilization. As a positive alternative, the authors discuss opportunities of management of the future and of the choice of a favorable path of development of mankind. These opportunities are based on the understanding of the principles of co-evolution of nature and mankind as well as of complex social and geopolitical structures.
Atomism and holism are considered as two opposite by implication but complementary approaches in the modern theory of complex self-organizing systems (theory of complexity). Atomism is connected with the consideration of nesting of complex structures in the world, their fractal organization, where we can reach elementary, further indivisible structural fragments on those basis complex scale invariant, self-similar spatio-temporal structures grow up. Besides, atomism is connected with the study of hierarchical organization of being and of elements, parts, subsystems out of which a whole structure is built. At the same time, it is shown in the article that the whole theory of complexity is penetrated by holism, and its holism is evolutionary by its character. Holism in evolution of complex self-organizing systems is coupled with the appearance of emergent properties of integral structural forms as well as with the discreteness, certain set of structures-attractors of evolution. The modern atomism can be brought into correlation with the notion of frames of perception in cognitive science. Proceeding from the system and evolutionary worldview, some arguments are put forward in favor of a hypothesis of the origins of the alphabetical writing in close connection with the studies of atoms in physical nature (Nidem, A.I. Kosyrev, V.G. Lysenko).
Set out the process of preparation and holding of computer modeling of digital devices on-Board equipment of space vehicles. These digital devices are protected from the risk of dielectric printed sites ESD, as a result of internal electrified, high conductivity of a dielectric - nano conductivity. A distinctive feature of the proposed process modeling is the count of nano conductivity dielectric printed sites on the parameters of the digital device.

The heuristic value of the synergetic models of evolution and self-organization of complex systems in epistemology and cognitive psychology, education and teaching, futures studies, social management activities and systems of global security is shown in the book. The book is addressed to a wide circle of readers: students, teachers, scientists who are specialized in different fields of natural sciences and the humanities as well as to all readers who strive for using recent results of science for reflections and achieving success in their own life.
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.
