To find your way in the vast Hittite Pantheon is by no means an easy task. In his Onomasticon of the Hittite Pantheon Ben van Gessel lists all Hittite gods as known from primary sources. Their names are listed as written in Hittite, Sumerian and Akkadian. Moreover, deities not mentioned by a proper name are given. The work ends with the unclassifiable fragments of names. Apart from answering questions about the (often confusing) orthography of the gods' names, each entry categorizes information on their epithets, shrines, priests and servants, cult places, attributes and feasts, as well as about the actual locations in the texts. Where necessary, the author refers to relevant literature.

By avoiding risk, are you also avoiding your life's full potential? Join acclaimed neurosurgeon Dr. Ben Carson as he explores the life-changing power of taking the risk, even if you're afraid. In our risk-avoidant culture, we place a high premium on safety. We insure our vacations. We check crash tests on cars. We extend the warranties on our appliances. But by insulating ourselves from the unknown--the natural risks of life--we miss the great adventure of living our lives to their fullest potential. Dr. Ben Carson spent his childhood as an at-risk child on the streets of Detroit, and he took big risks in performing complex surgeries on the brain and the spinal cord. Now, offering inspiring personal examples, Dr. Carson invites us to embrace risk in our own lives. In Take the Risk, Dr. Carson examines our safety-at-all-costs culture and the meaning of risk and security in our lives. Take the Risk guides you through an extensive examination of risk, including: Risk-taking in history An assessment of the real costs and rewards of risk Learning how to assess and accept risks Understanding how risk reveals the purpose of your life From a man whose life dramatically portrays the connection between great risks and greater successes, the insights Dr. Carson shares in Take the Risk will help you dispel your fear of risk in order to dream big, aim high, move with confidence, and reap the rewards of wise risk-taking. Praise for Take the Risk: "Whether you are a world-renowned neurosurgeon, a CEO, or a teacher, this book applies to anyone who ever wondered about the difference between the pacesetters and those who struggle to keep up. It is the pacesetters who Take the Risk, and this book explains when and why to take risks to empower everyone to become a trailblazer rather than a mere spectator. For anyone who wants to rise above mediocrity, this book is a must-read." --Armstrong Williams, author and radio host, The Armstrong Williams Show
This is a sequel to the author's book entitled “Entropy Demystified” (Published by World Scientific, 2007). The aim is essentially the same as that of the previous book by the author: to present Entropy and the Second Law as simple, meaningful and comprehensible concepts. In addition, this book presents a series of “experiments” which are designed to help the reader discover entropy and the Second Law. While doing the experiments, the reader will encounter three most fundamental probability distributions featuring in Physics: the Uniform, the Boltzmann and the Maxwell-Boltzmann distributions. In addition, the concepts of entropy and the Second Law will emerge naturally from these experiments without a tinge of mystery. These concepts are explained with the help of a few familiar ideas of probability and information theory.The main “value” of the book is to introduce entropy and the Second Law in simple language which renders it accessible to any reader who can read and is curious about the basic laws of nature. The book is addressed to anyone interested in science and in understanding natural phenomenon. It will afford the reader the opportunity to discover one of the most fundamental laws of physics — a law that has resisted complete understanding for over a century. The book is also designed to be enjoyable.There is no other book of its kind (except “Entropy Demystified” by the same author) that offers the reader a unique opportunity to discover one of the most profound laws — sometimes viewed as a mysterious — while comfortably playing with familiar games. There are no pre-requisites expected from the readers; all that the reader is expected to do is to follow the experiments or imagine doing the experiments and reach the inevitable conclusions.
This is a mathematics textbook with theorems and proofs. The choice of topics has been guided by the needs of computer science students. The method of semantic tableaux provides an elegant way to teach logic that is both theoretically sound and yet sufficiently elementary for undergraduates. In order to provide a balanced treatment of logic, tableaux are related to deductive proof systems. The book presents various logical systems and contains exercises. Still further, Prolog source code is available on an accompanying Web site. The author is an Associate Professor at the Department of Science Teaching, Weizmann Institute of Science.
Weyl group multiple Dirichlet series are generalizations of the Riemann zeta function. Like the Riemann zeta function, they are Dirichlet series with analytic continuation and functional equations, having applications to analytic number theory. By contrast, these Weyl group multiple Dirichlet series may be functions of several complex variables and their groups of functional equations may be arbitrary finite Weyl groups. Furthermore, their coefficients are multiplicative up to roots of unity, generalizing the notion of Euler products. This book proves foundational results about these series and develops their combinatorics. These interesting functions may be described as Whittaker coefficients of Eisenstein series on metaplectic groups, but this characterization doesn't readily lead to an explicit description of the coefficients. The coefficients may be expressed as sums over Kashiwara crystals, which are combinatorial analogs of characters of irreducible representations of Lie groups. For Cartan Type A, there are two distinguished descriptions, and if these are known to be equal, the analytic properties of the Dirichlet series follow. Proving the equality of the two combinatorial definitions of the Weyl group multiple Dirichlet series requires the comparison of two sums of products of Gauss sums over lattice points in polytopes. Through a series of surprising combinatorial reductions, this is accomplished. The book includes expository material about crystals, deformations of the Weyl character formula, and the Yang-Baxter equation.
This book documents an Islamic–Confucian school of scholarship that flourished, mostly in the Yangzi Delta, in the seventeenth and eighteenth centuries. Drawing on previously unstudied materials, it reconstructs the network of Muslim scholars responsible for the creation and circulation of a large corpus of Chinese Islamic written material—the so-called Han Kitab. Against the backdrop of the rise of the Manchu Qing dynasty, The Dao of Muhammad shows how the creation of this corpus, and of the scholarly network that supported it, arose in a context of intense dialogue between Muslim scholars, their Confucian social context, and China’s imperial rulers. Overturning the idea that participation in Confucian culture necessitated the obliteration of all other identities, this book offers insight into the world of a group of scholars who felt that their study of the Islamic classics constituted a rightful “school” within the Confucian intellectual landscape. These men were not the first Muslims to master the Chinese Classics. But they were the first to express themselves specifically as Chinese Muslims and to generate foundation myths that made sense of their place both within Islam and within Chinese culture.
Draws on interviews and archival material to document the extent of the atrocities committed by the Khmer Rouge in the late 1970s, which resulted in the deaths of one and a half million Cambodians.
Among the countless gangster films produced by Hollywood, few are as haunting, complex, or ingeniously crafted as White Heat (1948). Students of film history and screen writing will appreciate this treatment--an engaging study of teh various artistic elements that turned what might have been just another gangster film into an innovative classic of the genre and a model of cooperative filmmaking at its best. Crucial to White Heat's success, McGilligan stresses, was the rare manner in which every aspect of production coalesced: studio, script, cast, crew, and director.

This is open access book provides plenty of pleasant mathematical surprises. There are many fascinating results that do not appear in textbooks although they are accessible with a good knowledge of secondary-school mathematics. This book presents a selection of these topics including the mathematical formalization of origami, construction with straightedge and compass (and other instruments), the five- and six-color theorems, a taste of Ramsey theory and little-known theorems proved by induction. Among the most surprising theorems are the Mohr-Mascheroni theorem that a compass alone can perform all the classical constructions with straightedge and compass, and Steiner's theorem that a straightedge alone is sufficient provided that a single circle is given. The highlight of the book is a detailed presentation of Gauss's purely algebraic proof that a regular heptadecagon (a regular polygon with seventeen sides) can be constructed with straightedge and compass. Although the mathematics used in the book is elementary (Euclidean and analytic geometry, algebra, trigonometry), students in secondary schools and colleges, teachers, and other interested readers will relish the opportunity to confront the challenge of understanding these surprising theorems.
The series Advances in Industrial Contral aims to report and encourage technology transfer in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies ... , new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. From time to time a particular practical control problem emerges as a challenge to the design capabilities of the control community. One example has been the activated sludge process in wastewater systems where the process is highly nonlinear and measurements are few. A second example is the hard disk drive servo system. These widely used systems are critical to the operation of modem computing devices. They are nonlinear and demand a high-precision control system for the operations of track seeking and track following. There are also alternative actuation systems available to achieve these objectives. In this Advances in Industrial Control monograph B.M. Chen, T.H. Lee and V.
This book describes the mathematical underpinnings of algorithms used for molecular dynamics simulation, including both deterministic and stochastic numerical methods. Molecular dynamics is one of the most versatile and powerful methods of modern computational science and engineering and is used widely in chemistry, physics, materials science and biology. Understanding the foundations of numerical methods means knowing how to select the best one for a given problem (from the wide range of techniques on offer) and how to create new, efficient methods to address particular challenges as they arise in complex applications. Aimed at a broad audience, this book presents the basic theory of Hamiltonian mechanics and stochastic differential equations, as well as topics including symplectic numerical methods, the handling of constraints and rigid bodies, the efficient treatment of Langevin dynamics, thermostats to control the molecular ensemble, multiple time-stepping, and the dissipative particle dynamics method.
The goal of this monograph is to develop the theory of wavelet harmonic analysis on the sphere. By starting with orthogonal polynomials and functional Hilbert spaces on the sphere, the foundations are laid for the study of spherical harmonics such as zonal functions. The book also discusses the construction of wavelet bases using special functions, especially Bessel, Hermite, Tchebychev, and Gegenbauer polynomials.
Blanco County, Texas. It's one week before the start of deer hunting season, and everyone in town has come down with a case of... Buck Fever The fury begins with Red O'Brien and Billy Don Craddock, two drunken poachers who fire a shot in the direction of Blanco County's most important resident: a wide-eyed, white-tailed deer named Buck who lives on the Circle S ranch. Now Buck is on the loose, and no one knows where to find him: not Trey Sweeney, the man who took the bullet meant for Buck, albeit right in the flank of his own deer costume; not Tim Gray, the veterinarian who can't function very long without popping a few canine tranquilizers; and especially not Roy Swank, owner of the Circle S, who wants desperately to find Buck for reasons no one can quite understand. Navigating all this turmoil is Blanco County Game Warden John Marlin, with a little help from his best friend Phil and a beautiful nurse named Becky who seems too good to be true. But when a dead body turns up, the real mystery in madcap Blanco County soon boils down to a single question: Just who is hunting whom?
Using nothing more than undergraduate mathematical skills this book takes the reader from basic IS-LM style macro models to the state of the art literature on Dynamic Stochastic General Equilibrium.

In today's highly connected world, directory servers are the IT cornerstone of many businesses. These components of the corporate infrastructure are the foundation of authentication systems for internal and, more commonly, external user populations. Managing a directory server with several hundred internal users is not all that difficult. However, managing a directory server with several million external users in all 24 time zones throughout the world is a much more daunting task. IBM® Security Directory Server software can handle millions of entries, given the right architecture, configuration, and performance tuning. However, that tuning can differ greatly from tuning for a smaller server with only a few hundred thousand entries. Managing and tuning a directory server of this size requires a change in mindset. Tuning and performance must be a focus even before the hardware is ordered. A proactive approach must be taken after installation also, including the pretuning steps to better interface with other products to make installations and migrations successful, and then regular maintenance to keep the directory running smoothly. This IBM Redbooks® publication is the accumulation of lessons learned in many different real-world environments, including a 24-server fault tolerant configuration with more than 300 million entries. The authors pooled their knowledge and resources to provide the most comprehensive performance view possible, from hardware to software, sort heaps to buffer pools, and table cardinalities. In large directory server deployments, use this document as a guide for how to get the right fit for your environment.

They are scored for solo guitar, guitar trio, guitar and voice duo, and quartet with one or multiple voices. The majority of the works are through-composed and reflect the exploration of various harmonic, technical, and textural elements of the guitar. These pieces will present an array of challenges to the performer, including unusual techniques and alternate tunings
This timely book explores certain modern topics and connections at the interface of harmonic analysis, ergodic theory, number theory, and additive combinatorics. The main ideas were pioneered by Bourgain and Stein, motivated by questions involving averages over polynomial sequences, but the subject has grown significantly over the last 30 years, through the work of many researchers, and has steadily become one of the most dynamic areas of modern harmonic analysis. The author has succeeded admirably in choosing and presenting a large number of ideas in a mostly self-contained and exciting monograph that reflects his interesting personal perspective and expertise into these topics. —Alexandru Ionescu, Princeton University Discrete harmonic analysis is a rapidly developing field of mathematics that fuses together classical Fourier analysis, probability theory, ergodic theory, analytic number theory, and additive combinatorics in new and interesting ways. While one can find good treatments of each of these individual ingredients from other sources, to my knowledge this is the first text that treats the subject of discrete harmonic analysis holistically. The presentation is highly accessible and suitable for students with an introductory graduate knowledge of analysis, with many of the basic techniques explained first in simple contexts and with informal intuitions before being applied to more complicated problems; it will be a useful resource for practitioners in this field of all levels. —Terence Tao, University of California, Los Angeles
This book offers its readers a detailed overview of the synthesis of switched systems, with a focus on switching stabilization and intelligent control. The problems investigated are not only previously unsolved theoretically but also of practical importance in many applications: voltage conversion, naval piloting and navigation and robotics, for example. The book considers general switched-system models and provides more efficient design methods to bring together theory and application more closely than was possible using classical methods. It also discusses several different classes of switched systems. For general switched linear systems and switched nonlinear systems comprising unstable subsystems, it introduces novel ideas such as invariant subspace theory and the time-scheduled Lyapunov function method of designing switching signals to stabilize the underlying systems. For some typical switched nonlinear systems affected by various complex dynamics, the book proposes novel design approaches based on intelligent control concepts. It is a useful source of up-to-date design methods and algorithms for researchers studying switched systems and graduate students of control theory and engineering. In addition, it is a valuable reference resource for practising engineers working in switched-system control design. Readers should have a basic knowledge of linear, nonlinear and switched systems.

For the practitioner often interested in model building and analysis, we provide the cornerstone ideas.
Accurate, robust and fast image reconstruction is a critical task in many scientific, industrial and medical applications. Over the last decade, image reconstruction has been revolutionized by the rise of compressive imaging. It has fundamentally changed the way modern image reconstruction is performed. This in-depth treatment of the subject commences with a practical introduction to compressive imaging, supplemented with examples and downloadable code, intended for readers without extensive background in the subject. Next, it introduces core topics in compressive imaging – including compressed sensing, wavelets and optimization – in a concise yet rigorous way, before providing a detailed treatment of the mathematics of compressive imaging. The final part is devoted to recent trends in compressive imaging: deep learning and neural networks. With an eye to the next decade of imaging research, and using both empirical and mathematical insights, it examines the potential benefits and the pitfalls of these latest approaches.
Welding handicraft is one of the most primordial and traditional technics, mainly by manpower and human experiences. Weld quality and ef?ciency are, therefore, straitly limited by the welder’s skill. In the modern manufacturing, automatic and robotic welding is becoming an inevitable trend. However, it is dif?cult for au- matic and robotic welding to reach high quality due to the complexity, uncertainty and disturbance during welding process, especially for arc welding dynamics. The information acquirement and real-time control of arc weld pool dynamical process during automatic or robotic welding always are perplexing problems to both te- nologist in weld ?eld and scientists in automation. This book presents some application researches on intelligentized methodology in arc welding process, such as machine vision, image processing, fuzzy logical, neural networks, rough set, intelligent control and other arti?cial intelligence me- ods for sensing, modeling and intelligent control of arc welding dynamical process. The studies in the book indicate that the designed vision sensing and control s- tems are able to partially emulate a skilled welder’s intelligent behaviors: observing, estimating, decision-making and operating, and show a great potential and prom- ing prospect of arti?cial intelligent technologies in the welding manufacturing.

This volume brings together a lifetime’s achievement by one of America’s outstanding poets of the twentieth century. Though his earliest poems were published more than sixty years ago, Ben Belitt’s works in sum are likely to strike readers today with the force of unprecedented encounter. A poet of abundance and sometimes carnivalesque riotousness, Belitt also calls to mind the intensity and eruptiveness of Hopkins, the double passion for the infinite and the empirical exemplified by Neruda, and the lustrous word-painting associated with Keatsian Romanticism. But as these diverse predecessors suggest, Belitt is altogether an original, whose derivation is as multiple as his figuration. His concerns range from the appalled enthrallment with violence and disorder to the rage to learn how one can live in chance and confront the mandates of mortality. Scrupulously attentive to place, moving steadily in his works between northern vistas (Vermont, Block Island, New York) and southern (Mexico, Spain, Italy), Belitt is also haunted by a sense of fated displacements and havoc. Many of his best poems are elegiac, and his autobiographical works possess a posthumous air. In “This Scribe, My Hand,” perhaps his greatest poem in this genre, Belitt offers a powerful tribute to Keats while concurrently meditating upon his own forfeits and failures. The startling poèm-en-prose “School of the Soldier,” previously unpublished in book form, is also included. At once poignant in their confrontation of loss and defiant in their insistence upon connection, meaning, and wholeness, Belitt’s poems offer readers a fresh opportunity to discover “the fascination of what is difficult” and distinctive, marvelously rich and achingly human.
A life-enhancing tour through classic and contemporary poems that have made men cry: “The Holdens remind us that you don’t have to be an academic or a postgraduate in creative writing to be moved by verse….It’s plain fun” (The Wall Street Journal). Grown men aren’t supposed to cry…Yet in this fascinating anthology, one hundred men—distinguished in literature and film, science and architecture, theater and human rights—confess to being moved to tears by poems that continue to haunt them. Although the majority are public figures not prone to crying, here they admit to breaking down, often in words as powerful as the poems themselves. Their selections include classics by visionaries, such as Walt Whitman, W.H. Auden, and Philip Larkin, as well as modern works by masters, including Billy Collins, Seamus Heaney, Derek Walcott, and poets who span the globe from Pablo Neruda to Rabindranath Tagore. The poems chosen range from the sixteenth century to the twenty-first, with more than a dozen by women, including Mary Oliver, Elizabeth Bishop, and Gwendolyn Brooks. Their themes range from love in its many guises, through mortality and loss, to the beauty and variety of nature. All are moved to tears by the exquisite way a poet captures, in Alexander Pope’s famous phrase, “what oft was thought, but ne’er so well express’d.” From J.J. Abrams to John le Carré, Salman Rushdie to Jonathan Franzen, Daniel Radcliffe to Nick Cave to Stephen Fry, Stanley Tucci to Colin Firth to the late Christopher Hitchens, this collection delivers private insight into the souls of men whose writing, acting, and thinking are admired around the world. “Everyone who reads this collection will be roused: disturbed by the pain, exalted in the zest for joy given by poets” (Nadine Gordimer, winner of the Nobel Prize for literature).
In this exhilarating look at cities, past and future, Ben Wilson proposes that, in our world of rising seas and threatening weather, the natural world may prove the city's savior "Illuminating...Wilson leaves readers with hope about the future of efforts to preserve the ecosystems that surround us, as well as a new perspective that looks beyond the concrete and asphalt when walking along a city’s streets."—Associated Press Since the beginning of civilization, humans have built cities to wall nature out, then glorified it in beloved but quite artificial parks. In Urban Jungle Ben Wilson—the author of Metropolis, a seven-thousand-year history of cities that the Wall Street Journal called “a towering achievement”—looks to the fraught relationship between nature and the city for clues to how the planet can survive in an age of climate crisis. Whether it was the market farmers of Paris, Germans in medieval forest cities, or the Aztecs in the floating city of Tenochtitlan, pre-modern humans had an essential bond with nature. But when the day came that water was piped in and food flown from distant fields, that relationship was lost. Today, urban areas are the fastest-growing habitat on Earth and in Urban Jungle Ben Wilson finds that we are at last acknowledging that human engineering is not enough to protect us from extremes of weather. He takes us to places where efforts to rewild the city are under way: to Los Angeles, where the city’s concrete river will run blue again, to New York City, where a bleak landfill will be a vast grassland preserve. The pinnacle of this strategy will be Amsterdam: a city that is its own ecosystem, that makes no waste and produces its own energy. In many cities, Wilson finds, nature is already thriving. Koalas are settling in Brisbane, wild boar may raid your picnic in Berlin. Green canopies, wildflowers, wildlife: the things that will help cities survive, he notes, also make people happy. Urban Jungle offers the pleasures of history—how backyard gardens spread exotic species all over the world, how war produces biodiversity—alongside a fantastic vision of the lush green cities of our future. Climate change, Ben Wilson believes, is only the latest chapter in the dramatic human story of nature and the city.
Vertex algebras are algebraic objects that encapsulate the concept of operator product expansion from two-dimensional conformal field theory. Vertex algebras are fast becoming ubiquitous in many areas of modern mathematics, with applications to representation theory, algebraic geometry, the theory of finite groups, modular functions, topology, integrable systems, and combinatorics. This book is an introduction to the theory of vertex algebras with a particular emphasis on the relationship with the geometry of algebraic curves. The notion of a vertex algebra is introduced in a coordinate-independent way, so that vertex operators become well defined on arbitrary smooth algebraic curves, possibly equipped with additional data, such as a vector bundle. Vertex algebras then appear as the algebraic objects encoding the geometric structure of various moduli spaces associated with algebraic curves. Therefore they may be used to give a geometric interpretation of various questions of representation theory. The book contains many original results, introduces important new concepts, and brings new insights into the theory of vertex algebras. The authors have made a great effort to make the book self-contained and accessible to readers of all backgrounds. Reviewers of the first edition anticipated that it would have a long-lasting influence on this exciting field of mathematics and would be very useful for graduate students and researchers interested in the subject. This second edition, substantially improved and expanded, includes several new topics, in particular an introduction to the Beilinson-Drinfeld theory of factorization algebras and the geometric Langlands correspondence.
This two-volume, 1100 pages, 38 chapters book is a significantly expanded, revised and updated version of the monograph by the authors published in 2013 (Ben-Dor, G, Dubinsky, A, Elperin, T, 'High Speed Penetration Dynamics: Engineering Models and Methods,' Singapore: World Scientific Publishing Company). The contents increased by 60%, the number of titles in bibliography doubled and reached 1600; and the scope covers a range of new topics related to hypervelocity penetration, along with high-speed impact.Presented material is structured into two parts. The first part includes description and analysis of practically all known engineering models for calculating high-speed penetration of projectiles into concrete, metals, geological shields, adobe, and gelatine.The second part focuses on the use of approximate models for solving conventional and non-standard problems of penetration mechanics including prediction and optimization of protective properties of monolithic and multi-layered shields against high-speed projectiles and space debris; shape optimization of high-speed projectiles penetrating into various media; modelling of penetration and optimal control of penetrators equipped with jet thrusters; and investigation of the efficiency and optimization of segmented projectiles. The book includes comprehensive overviews on basic classes of problems in high-speed penetration mechanics.This is a indispensable reference guide for scientists, engineers, and students specializing in the field of high-speed and hypervelocity penetration mechanics.
