World Energy and Transition to Sustainable Development

World Energy and Transition to Sustainable Development

Lev S. Belyaev; Oleg V. Marchenko; Sergei P. Filippov; Sergei V. Solomin; Tatyana B. Stepanova; Alexei L. Kokorin

Springer
2011
nidottu
This book presents the results of a study of long-term perspectives for energy development of the world and its main regions, performed at the Siberian Energy Institute of the Russian Academy of Sciences (Energy Systems Institute since 1998). The methodological approach, the 10-regional Global Energy Model (GEM-10R) of the world energy system, energy demand forecasts, data on energy resources and energy technologies, and results of calculations based on mathematical models are described. Particular attention is given to determination of energy requirements and peculiarities of its technological structure that are caused by mankind's necessary transition to sustainable development. Economic and ecological consequences of constraints on greenhouse gas emissions and scales of nuclear energy production, as well as assistance of developed countries to developing ones are investigated. Problems of cheap oil, gas and uranium resources depletion, fuel price growth, synthetic fuel production and new energy technology implementation are analysed. The book is intended for specialists in energy and economics, as well as students and postgraduate students of technical high schools and universities. ac

Microcavities

Microcavities

Alexey V. Kavokin; Jeremy J. Baumberg; Guillaume Malpuech; Fabrice P. Laussy

Oxford University Press
2017
sidottu
Microcavities are semiconductor, metal, or dielectric structures providing optical confinement in one, two or three dimensions. At the end of the 20th century, microcavities have attracted attention due to the discovery of a strong exciton-light coupling regime allowing for the formation of superposition light-matter quasiparticles: exciton-polaritons. In the following century several remarkable effects have been discovered in microcavities, including the Bose-Einstein condensation of exciton-polaritons, polariton lasing, superfluidity, optical spin Hall and spin Meissner effects, amongst other discoveries. Currently, polariton devices exploiting the bosonic stimulation effects at room temperature are being developed by laboratories across the world. This book addresses the physics of microcavities: from classical to quantum optics, from a Boltzmann gas to a superfluid. It provides the theoretical background needed for understanding the complex phenomena in coupled light-matter systems, and it presents a broad overview of experimental progress in the physics of microcavities.

Gravity, Magnetic and Electromagnetic Gradiometry

Gravity, Magnetic and Electromagnetic Gradiometry

Alexey V. Veryaskin

Morgan Claypool Publishers
2018
nidottu
Gradiometry is a multidisciplinary area that combines theoretical and applied physics, ultra-low noise electronics, precision engineering, and advanced signal processing. All physical fields have spatial gradients that fall with distance from their sources more rapidly than the field strength itself. This makes the gradient measurements more difficult. However, there has been a considerable investment, both in terms of time and money, into the development of various types of gradiometers driven by the extremely valuable type of information that is contained in gradients. Applications include the search for oil, gas, and mineral resources, GPS-free navigation, defence, space missions, medical research, and some other applications.The author describes gravity gradiometers, magnetic gradiometers, and electromagnetic (EM) gradiometers. The first two types do not require any active sources of the primary physical fields whose gradients are measured, such as gravity field and ambient magnetic field. EM gradiometers do require a primary EM field, pulsed, or sinusoidal, which propagates through media and creates a secondary EM field. The latter one contains information about the non uniformness of electromagnetically active media such as conductivity and magnetic permeability contrasts. These anomalies are the boundaries of mineral deposits, oil and gas traps, underground water reserves, buried artifacts, unexploded ordnance (UXO), nuclear submarines, and even cancerous human tissue.This book provides readers with a comprehensive introduction, history, potential applications, and current developments in relation to some of the most advanced technologies in the 21st Century. Most of the developments are strictly controlled by Defence Export Control rules and regulations, introduced in all developed countries that typically require permission to transfer relevant information from one country to another. The book is based on the materials that have been available in public domain such as scientific journals, conferences, extended abstracts, and online presentations. In addition, medical applications of EM gradiometers are exempt from any control, and some new results relevant to breast cancer early detection research are published in this book for the first time.

Calculus and Mechanics on Two-Point Homogenous Riemannian Spaces

Calculus and Mechanics on Two-Point Homogenous Riemannian Spaces

sidottu
Mathematics develops both due to demands of other sciences and due to its internal logic. The latter fact explains the attention of mathematicians to many problems, which are in close connection with basic mathematical notions, even if these problems have no direct practical applications. It is well known that the space of constant curvature is one of the basic geometry notion [208], which induced the wide ?eld for investigations. As a result there were found numerous connections of constant curvature spaces with other branches of mathematics, for example, with integrable partial dif- 1 ferential equations [36, 153, 189] and with integrable Hamiltonian systems [141]. Geodesic ?ows on compact surfaces of a constant negative curvature (with the genus 2) generate many test examples for ergodic theory (see also 3 [183] and the bibliography therein). The hyperbolic space H (R) is the space of velocities in special relativity (see Sect. 7.4.1) and also arises as space-like sections in some models of general relativity.

Critical Levels in the Development of Natural Systems

Critical Levels in the Development of Natural Systems

Alexey V. Zhirmunsky; Victor I. Kuzmin

Springer-Verlag Berlin and Heidelberg GmbH Co. K
2014
nidottu
This book deals with general quantitative regularities of the alteration of evolutionary and reconstruction (critical) periods of development. An equation and a model of development are introduced which generalize a wide range of commonly accepted models, allowing the analysis of the characteristics of processes occurring on different structural levels of natural system organization. On the basis of this model, a hierarchy of critical constants has been established, applicable to, for example, geological history, cyclicity in the individual development of animals, structures of population and ecological systems, as well as to the perception of acoustical signals by man.

Conservation of Living Nature and Resources

Conservation of Living Nature and Resources

Alexey V. Yablokov; Sergey A. Ostroumov

Springer-Verlag Berlin and Heidelberg GmbH Co. K
2012
nidottu
This book is based on our two books, published in the USSR and translated in a number of other countries Conservation of living nature: problems and perspectives (1983) and The levels of conservation of living nature (1985). It differs from the vast majority of the numerous books on conservation and environment, which are mainly devoted either to specific problems of conservation of certain taxons, or to problems of conservation of prescribed regions, or to general issues of environmental conservation in toto, while the problems of the conservation of living nature are represented only to a small degree. Our book is one of the volumes - at present not numerous - that place a high value on the diversity ofliving nature as the basis for the existence and development of mankind on the Earth. Living nature, besides its own intrinsic value, at all times was, is now and will ever remain the sole, unique and indispensable resource and provider for mankind.
