Concentrating on the process of breaking and protecting Web applications written in PHP, this book also considers related Web programming topics such as client technologies (HTML, cookies, JavaScript), application protocols (HTTP, SMTP), SQL query language, and the breaking and protecting of the Apache Web server. Because these techniques can only be achieved by practical work, the book is divided into two parts: one covering the problem (puzzles) and one devoted to solving the problem. Evaluating the main problem for many Web programmers protecting their applications from being hacked—that they think differently than hackers—this book allows the reader to think like a hacker and understand the techniques they use.

Iterative Methods for Linear Systems?offers a mathematically rigorous introduction to fundamental iterative methods for systems of linear algebraic equations. The book distinguishes itself from other texts on the topic by providing a straightforward yet comprehensive analysis of the Krylov subspace methods, approaching the development and analysis of algorithms from various algorithmic and mathematical perspectives, and going beyond the standard description of iterative methods by connecting them in a natural way to the idea of preconditioning.??
This definitive anthology gathers stories, essays, memoirs, excerpts from novels, and poems by more than 130 Jewish writers of the past two centuries who worked in the Russian language. It features writers of the tsarist, Soviet, and post-Soviet periods, both in Russia and in the great emigrations, representing styles and artistic movements from Romantic to Postmodern. The authors include figures who are not widely known today, as well as writers of world renown. Most of the works appear here for the first time in English or in new translations. The editor of the anthology, Maxim D. Shrayer of Boston College, is a leading authority on Jewish-Russian literature. The selections were chosen not simply on the basis of the author's background, but because each work illuminates questions of Jewish history, status, and identity. Each author is profiled in an essay describing the personal, cultural, and historical circumstances in which the writer worked, and individual works or groups of works are headnoted to provide further context. The anthology not only showcases a wide selection of individual works but also offers an encyclopedic history of Jewish-Russian culture. This handsome two-volume set is organized chronologically. The first volume spans the nineteenth century and the first part of the twentieth century, and includes the editor's extensive introduction to the Jewish-Russian literary canon. The second volume covers the period from the death of Stalin to the present, and each volume includes a corresponding survey of Jewish-Russian history by John D. Klier of University College, London, as well as detailed bibliographies of historical and literary sources.

The present book carefully studies the blow-up phenomenon of solutions to partial differential equations, including many equations of mathematical physics. The included material is based on lectures read by the authors at the Lomonosov Moscow State University, and the book is addressed to a wide range of researchers and graduate students working in nonlinear partial differential equations, nonlinear functional analysis, and mathematical physics.

At the heart of this book is the generalized theoretical approach that is applied to investigate the geoelectrical structure of the Earth’s mantle. It also analyzes the results of regional and global induction sounding of the Earth’s mantle and compares them with the results obtained by other geophysical methods. The generalized theoretical approach employs the Induction Law as a basis for identifying extended relations between magnetic field components, including their plane divergence, impedances and spatial derivatives. The estimations of impedance values and spatial derivatives are performed using the theory of stochastic processes. The book also considers the external sources of magnetic fields used for sounding the Earths mantle from the modern theory perspective, as well as the problem of coincidence of magneto-variation and magnetotelluric methods. Further, it discusses secular variations in the Earth’s resistance caused by non-induction sources, factors that are correlated with the number of earthquakes in the region and shifted in time with global indexes. It is a valuable resource for scientists applying deep induction soundings or interested in the structures of and processes in the Earth’s interior.
The monograph is devoted to the study of initial-boundary-value problems for multi-dimensional Sobolev-type equations over bounded domains. The authors consider both specific initial-boundary-value problems and abstract Cauchy problems for first-order (in the time variable) differential equations with nonlinear operator coefficients with respect to spatial variables. The main aim of the monograph is to obtain sufficient conditions for global (in time) solvability, to obtain sufficient conditions for blow-up of solutions at finite time, and to derive upper and lower estimates for the blow-up time. The abstract results apply to a large variety of problems. Thus, the well-known Benjamin-Bona-Mahony-Burgers equation and Rosenau-Burgers equations with sources and many other physical problems are considered as examples. Moreover, the method proposed for studying blow-up phenomena for nonlinear Sobolev-type equations is applied to equations which play an important role in physics. For instance, several examples describe different electrical breakdown mechanisms in crystal semiconductors, as well as the breakdown in the presence of sources of free charges in a self-consistent electric field. The monograph contains a vast list of references (440 items) and gives an overall view of the contemporary state-of-the-art of the mathematical modeling of various important problems arising in physics. Since the list of references contains many papers which have been published previously only in Russian research journals, it may also serve as a guide to the Russian literature.
This book uses the Lagrangian approach, especially useful and convenient for studying large-scale transport and mixing in the ocean, to present a detailed view of ocean circulation. This approach focuses on simulations and on monitoring the trajectories of fluid particles, which are governed by advection equations. The first chapter of the book is devoted to dynamical systems theory methods, which provide the framework, methodology and key concepts for the Lagrangian approach. The book then moves on to an analysis of chaotic mixing and cross-stream transport in idealized models of oceanic meandering currents like the Gulfstream in the Atlantic, the Kuroshio in the Pacific, and Antarctic Circumpolar Current, after which the current state of physical oceanography is reviewed. The latter half of the book applies the techniques and methods already described in order to study eddies, currents, fronts and large-scale mixing and transport in the Far-Eastern seas and the north-western part of the Pacific Ocean. Finally, the book concludes with a discussion of Lagrangian simulation and monitoring of water contamination after the Fukushima disaster of 2011. The propagation of Fukushima-derived radionuclides, surface transport across the Kuroshio Extension current, and the role of mesoscale eddies in the transport of Fukushima-derived cesium isotopes in the ocean are examined, and a comparison of simulation results with actual measurements are presented.Written by some of the world leaders in the application of Lagrangian methods in oceanography, this title will be of benefit to the oceanographic community by presenting the necessary background of the Lagrangian approach in an accessible manner.
The Russian coal sector today faces challenges in the form of global decarbonization, sanctions, and difficulties in retaining market access and competitiveness. This new market environment warrants an examination of what lessons can be drawn from the past tribulations of one of Russia’s most iconic and strategically important industries. This book analyzes the Russian coal industry developments in historical and political contexts, including those of energy transition. The key tenets of contemporary dialogue between Russia and those who advocate for a speedy energy transition to phase out coal are presented. The book addresses the question of the coal industry as a sacrifice for the sake of Russia’s rapprochement with the West. The contribution of this book, therefore, is filling the gap between two large research inquiries – climate change mitigation and energy transition on the one hand, and the existing large coal industry of a given country on the other.
