This book discusses the physics of conductive channel development in space, air and vacuums and summarizes the attempts to create super-long conductive channels to study the upper atmosphere and to complete specific tasks related to energy transmission from the space to earth with high-voltage high repetition rate electrical sources. Conductive channels are produced by the laser jet engine vehicle-propulsion under the influence of powerful high repetition rate pulse-periodic laser radiation by CO2-laser, solid state Nd YAG,HF/DF laser systems generated with each pulse of the powerful laser conductive dust plasma. The book also presents the experimental and theoretical results of conductive canal modeling: the laser jet engine vehicle “Impulsar”, which can reach the lower layers of the ionosphere in several hundred seconds. Further, the book explores the development of lightning protection systems. The so-called long laser spark is generated to provide the conditions for connecting a thunderstorm cloud with a grounded metal rod, i.e. a classical lightning rod. Such conductivity channels can be used for energy transmission, overvoltage protection systems, transport of charged particle beams and plasma antennas. It provides the theoretical and experimental basis of high repetition rate P-P mode of operation for high power lasers (COIL, HF/DF, CO2,Nd YAG). It describes high efficiency and excellent beam quality disk lasers used for numerous applications, including surface treatment of dielectric materials in microelectronics, cutting, drilling, welding, polishing and cleaning of the surface and other technological operations. Lastly it investigates how megawatt mono-module disk lasers could be used to solve various problems: small satellites launched by lasers, formation of super-long conducting channels in space and atmosphere, cleaning of the near-earth space from the space debris and related applications.

The 91st London Mathematical Society Durham Symposium took place from July 5th to 15th 2010, with more than 100 international participants attending. The Symposium focused on Numerical Analysis of Multiscale Problems and this book contains 10 invited articles from some of the meeting's key speakers, covering a range of topics of contemporary interest in this area. Articles cover the analysis of forward and inverse PDE problems in heterogeneous media, high-frequency wave propagation, atomistic-continuum modeling and high-dimensional problems arising in modeling uncertainty. Novel upscaling and preconditioning techniques, as well as applications to turbulent multi-phase flow, and to problems of current interest in materials science are all addressed. As such this book presents the current state-of-the-art in the numerical analysis of multiscale problems and will be of interest to both practitioners and mathematicians working in those fields.

These are the proceedings of the 19th international conference on domain decomposition methods in science and engineering. Domain decomposition methods are iterative methods for solving the often very large linear or nonlinear systems of algebraic equations that arise in various problems in mathematics, computational science, engineering and industry. They are designed for massively parallel computers and take the memory hierarchy of such systems into account. This is essential for approaching peak floating point performance. There is an increasingly well-developed theory which is having a direct impact on the development and improvement of these algorithms.

This monograph is devoted to the study of multiscale model reduction methods from the point of view of multiscale finite element methods. Multiscale numerical methods have become popular tools for modeling processes with multiple scales. These methods allow reducing the degrees of freedom based on local offline computations. Moreover, these methods allow deriving rigorous macroscopic equations for multiscale problems without scale separation and high contrast. Multiscale methods are also used to design efficient solvers. This book offers a combination of analytical and numerical methods designed for solving multiscale problems. The book mostly focuses on methods that are based on multiscale finite element methods. Both applications and theoretical developments in this field are presented. The book is suitable for graduate students and researchers, who are interested in this topic.
