A Horse's World


A Horse's World: A Neuroscientist's Journey into the Equine Mind
English | 2026 | ISBN: 0316582581 | 309 Pages | EPUB (True) | 11 MB
The bond between horses and humans has been treasured for centuries. Horses have served as aids to civilization, subjects of the earliest art, vehicles for global trade, and extreme athletes. Still, their cognitive processes have remained mysterious, even to the humans who love them.

A History of Jungle Warfare


A History of Jungle Warfare: From the Earliest Days to the Battlefields of Vietnam
English | 2021 | ISBN: 1473847532 | 236 Pages | EPUB (True) | 17 MB
A world where little light penetrates. Of dense vegetation, tangled roots, fetid mud and swamps. Where the helicopter, sophisticated weaponry and technology have revolutionized military combat. But where survival still depends on acute observation and listening for the slightest sound. The jungle. Backdrop to one of the most gruelling forms of warfare. To wars that in recent times have changed the course of history. The subject of this expert, extensively illustrated study by Bryan Perrett.

A History of China-U.S. Relations (1949-1972)


A History of China-U.S. Relations (1949-1972)
English | 2026 | ISBN: 9819554527 | 521 Pages | PDF (True) | 17 MB
This book presents a panorama of the history of China-U.S. relations from 1949 to 1972 and covers a wide range of topics in this significant period: China-U.S. Confrontation in the Korean War, American Containment of China from the 1950s to 1970s, Two Crises in the Taiwan Strait, China-U.S. Ambassadorial Talks, China-U.S. Confrontation in Indochina, and Rapprochement, and Dr. Kissinger and President Nixon's visit to China in 1971 and 1972. The transformation of U.S. policy toward China from containment to rapprochement indicated the attitudinal change of American decision-makers on China's role in U.S. grand strategy and their perception of bilateral relations. China's decision to seek reconciliation with the United States in the late 1960s and early 1970s also embodied its policy adjustment towards the United States. In the toughest moments of the Cold War, it took great courage, wisdom and leadership to open a new chapter in bilateral relations. History is a mirror that illuminates the present and the future. At a critical China-U.S. relations today, this timely publication of Professor Tao Wenzhao may enlighten us as to steering this vital relationship toward a healthy course in the world of enormous challenges.

A Historical Casebook of Wage Formation


A Historical Casebook of Wage Formation: Wage Determination and Wage Bargains, 1500-1950
English | 2026 | ISBN: 3031919297 | 423 Pages | PDF EPUB (True) | 17 MB
Recent literature has revived an established interest in the economic history of wage formation, underlining the gaps still existing in our understanding of wages' composition, quantification, and process of structuring. This collection will shed light on these points, examining diverse topics including in-kind and monetary payments, bonuses and supplements, work contracts, differentials between skilled and unskilled workers, women's work, slavery and coerced labour contracts, and wages in both diachronic and comparative perspective: how wages' structure and composition changes across times and spaces (both in terms of geographical areas and urban-rural environments). The book presents case studies from various geographical areas (from South America to India) from the preindustrial period to the contemporary age and features related contributions on the manufacturing sector, agriculture, mining, and public sectors. The book will be a valuable resource for scholars and students of pre-industrial labour markets in economic, social and labour history.

A Guide to Generalized Functions


A Guide to Generalized Functions: Linear, Nonlinear, Random, and Infinite Dimensional Distributions
English | 2026 | ISBN: 3032091837 | 264 Pages | PDF EPUB (True) | 27 MB
The aim of the present work is to give a unifying treatment of the four faces of the theory of generalized functions - linear, nonlinear, random and infinite dimensional distributions. The book deals with all of these categories in a comparative and interconnected way, giving a broad overview without getting lost in too many details. This original presentation touches upon a number of mathematical areas, such as functional analysis, theory of functions, measure theory, operator theory, differentiable manifolds, probability theory, stochastic processes and stochastic analysis. For example, in one of the chapters it builds a bridge from Gaussian measures on Hilbert spaces, Malliavin calculus, Wiener chaos, Meyer-Watanabe distributions, Hida distributions and White Noise Analysis up to Kondratiev spaces, ending with Colombeau versions. Any researcher who is looking for an overview on the state-of-the art, or to specialize in the theory of distributions, will find this book a useful resource.

A Differential Quadrature Hierarchical Finite Element Method


A Differential Quadrature Hierarchical Finite Element Method
English | 2022 | ISBN: 9811236755 | 651 Pages | PDF (True) | 69 MB
The differential quadrature hierarchical finite element method (DQHFEM) was proposed by Bo Liu. This method incorporated the advantages and the latest research achievements of the hierarchical finite element method (HFEM), the differential quadrature method (DQM) and the isogeometric analysis (IGA). The DQHFEM also overcame many limitations or difficulties of the three methods.This unique compendium systemically introduces the construction of various DQHFEM elements of commonly used geometric shapes like triangle, tetrahedrons, pyramids, etc. Abundant examples are also included such as statics and dynamics, isotropic materials and composites, linear and nonlinear problems, plates as well as shells and solid structures.This useful reference text focuses largely on numerical algorithms, but also introduces some latest advances on high order mesh generation, which often has been regarded as the major bottle neck for the wide application of high order FEM.

A Course of Stochastic Analysis (2nd Edition)


A Course of Stochastic Analysis
English | 2026 | ISBN: 303220481X | 297 Pages | PDF EPUB (True) | 21 MB
This thoroughly updated second edition offers a unified, modern pathway from the Kolmogorov foundations of probability to the tools of stochastic calculus-and on to applications in finance, statistics, and risk. With clarity and breadth, it develops martingale and semimartingale theory alongside stochastic differential equations, keeping both discrete- and continuous-time viewpoints in play.

A Billiard Problem in Nonlinear Dissipative Systems


A Billiard Problem in Nonlinear Dissipative Systems
English | 2026 | ISBN: 9819575605 | 147 Pages | PDF EPUB (True) | 24 MB
This book addresses a new class of billiard problems, focusing on the motion of a self-propelling disk in a nonlinear dissipative system on a rectangular domain. Unlike classical billiards, which have been extensively studied in mathematics, this setting introduces unique dynamics inspired by experiments with camphor disks floating on water-a well-known phenomenon in nonlinear science. Laboratory observations reveal two striking properties: (i) the disk reflects without physical collision at the boundary, and (ii) the reflection angle exceeds the incidence angle, differing from the perfect elastic reflection of classical billiards. These features suggest that the behavior of a self-propelling disk is fundamentally distinct from classical billiard motion.
