Free Download Analysis and Decision Making in Uncertain Systems by Zdzislaw Bubnicki English | PDF | 2004 | 377 Pages | ISBN : 1852337729 | 22.6 MB Problems, methods and algorithms of decision making based on an uncertain knowledge now create a large and intensively developing area in the field of knowledge-based decision support systems. The main aim of this book is to present a unified, systematic description of analysis and decision problems in a wide class of uncertain systems described by traditional mathematical models and by relational knowledge representations. A part of the book is devoted to new original ideas introduced and developed by the author: the concept of uncertain variables and the idea of a learning process consisting in knowledge validation and updating. In a certain sense this work may be considered as an extension of the author's monograph Uncertain Logics, Variables and Systems (Springer-Verlag, 2002). In this book it has been shown how the different descriptions of uncertainty based on random, uncertain and fuzzy variables may be treated uniformly and applied as tools for general analysis and decision problems, and for specific uncertain systems and problems (dynamical control systems, operation systems, knowledge-based pattern recognition under uncertainty, task allocation in a set of multiprocessors with uncertain execution times, and decision making in an assembly system as an example of an uncertain manufacturing system). The topics and the organization of the text are presented in Chapter 1 (Sects 1. 1 and 1. 4). The material presented in the book is self-contained.  Free Download An Introduction to the History of Structural Mechanics Part I: Statics and Resistance of Solids by Edoardo Benvenuto English | PDF | 1991 | 324 Pages | ISBN : 1461277450 | 31.3 MB This book is one of the finest I have ever read. To write a foreword for it is an honor, difficult to accept. Everyone knows that architects and master masons, long before there were mathematical theories, erected structures of astonishing originality, strength, and beauty. Many of these still stand. Were it not for our now acid atmosphere, we could expect them to stand for centuries more. We admire early architects' visible success in the distribution and balance of thrusts, and we presume that master masons had rules, perhaps held secret, that enabled them to turn architects' bold designs into reality. Everyone knows that rational theories of strength and elasticity, created centuries later, were influenced by the wondrous buildings that men of the sixteenth, seventeenth, and eighteenth centuries saw daily. Theorists know that when, at last, theories began to appear, architects distrusted them, partly because they often disregarded details of importance in actual construction, partly because nobody but a mathematician could understand the aim and func tion of a mathematical theory designed to represent an aspect of nature. This book is the first to show how statics, strength of materials, and elasticity grew alongside existing architecture with its millenial traditions, its host of successes, its ever-renewing styles, and its numerous problems of maintenance and repair. In connection with studies toward repair of the dome of St. Peter's by Poleni in 1743, on p.  Free Download An Introduction to Riemann-Finsler Geometry by D. Bao , S.-S. Chern , Z. Shen English | PDF | 2000 | 453 Pages | ISBN : 038798948X | 55.4 MB In Riemannian geometry, measurements are made with both yardsticks and protractors. These tools are represented by a family of inner-products. In Riemann-Finsler geometry (or Finsler geometry for short), one is in principle equipped with only a family of Minkowski norms. So ardsticks are assigned but protractors are not. With such a limited tool kit, it is natural to wonder just how much geometry one can uncover and describe?  Free Download An Introduction to Hydrodynamics and Water Waves by Bernard Méhauté English | PDF | 1976 | 326 Pages | ISBN : 3642855695 | 55.6 MB Hydrodynamics is the science which deals with the v motion of liquid in the macroscopic sense. It is essentially a field which is regarded as applied mathematics because it deals with the mathematical treatments of basic equations for a fluid continuum obtained on a purely Newtonian basis. It is also the foundation of hydraulics, which, as an art, has to compromise with the rigorous mathematical treatments because of nonlinear effects, inherent instability, turbulence, and the complexity of" boundary conditions" encountered in engineering practice. Therefore, this book can be considered as the text for a course in basic hydrodynamics, as well as for a course in the fundamentals of hydraulic and related engineering disciplines.  Free Download Saber Elaydi, "An Introduction to Difference Equations" English | 2005 | pages: 547 | ISBN: 1441920013, 0387230599 | PDF | 4,5 mb A must-read for mathematicians, scientists and engineers who want to understand difference equations and discrete dynamics  Free Download Ann Vanderhoof, "An Embarrassment of Mangoes: A Caribbean Interlude" English | 2005 | pages: 305 | ISBN: 0767914279, 0767914023 | EPUB | 0,7 mb Under the Tuscan Sun meets the wide-open sea . . . An Embarrassment of Mangoes is a delicious chronicle of leaving the type-A lifestyle behind - and discovering the seductive secrets of life in the Caribbean.  Free Download An Economic History of British Steam Engines, 1774-1870: A Study on Technological Diffusion by Haris Kitsikopoulos English | PDF EPUB (True) | 2023 | 373 Pages | ISBN : 3031273613 | 10.5 MB This book traces the diffusion trajectory of the second and third generation of British steam engines, the Watt and high-pressure models, covering the period 1774 to 1870. It begins by subjecting to econometric analysis the latest version of Dr. Kanefsky's database on 18th century steam engines coming up with an upward revision of the total amount of horsepower installed by 1800. Subsequent chapters delve into the determinants of the diffusion process through the third quarter of the 19th century relating to engines used both in mining and industry as well as transportation (railways, steam cars).  Free Download An Axiomatic Basis for Quantum Mechanics: Volume 1 Derivation of Hilbert Space Structure by Günther Ludwig English | PDF | 1985 | 254 Pages | ISBN : 3642700314 | 33 MB This book is the first volume of a two-volume work, which is an improved version of a preprint [47] published in German. We seek to deduce the funda mental concepts of quantum mechanics solely from a description of macroscopic devices. The microscopic systems such as electrons, atoms, etc. must be detected on the basis of the macroscopic behavior of the devices. This detection resembles the detection of the dinosaurs on the basis offossils. In this first volume we develop a general description of macroscopic systems by trajectories in state spaces. This general description is a basis for the special de scription of devices consisting of two parts, where the first part is acting on the second. The microsystems are discovered as systems transmitting the action. Axioms which describe general empirical structures of the interactions between the two parts of each device, give rise to a derivation of the Hilbert space structure of quantum mechanics. Possibly, these axioms (and consequently the Hilbert space structure) may fail to describe other realms than the structure of atoms and mole cules, for instance the "elementary particles". This book supplements ref. [2]. Both together not only give an extensive foundation of quantum mechanics but also a solution in principle of the measuring problem.  Free Download Dahris Martin, "Among The Faithful: Tunisia in the 1920s" English | 2003 | pages: 174 | ISBN: 1900209047 | EPUB | 0,4 mb Dahris Martin, a young American, arrived in the holy city of Kairouan in the late 1920s. There she was privileged to witness traditional Tunisian domestic life from within. Her unique portrait of the city and people tells of bare-foot pilgrims and Bedouin, the deflowering of virgin brides, spirit possession, and dances held for djinn. The author was born in New York, studied at Columbia, and worked for Doubleday, before embarking for Tunisia. Originally published in 1937.  Free Download Peter Dennis, "Amiens 1918: The Black Day of the German Army" English | 2008 | pages: 97 | ISBN: 1846033039 | PDF | 13,3 mb Through the spring of 1918 of World War I (1914-1918), Germany had been on the offensive on the Western Front but had failed to break the Allies at any point. In July they had been forced back from the river Marne and were once again on the defensive. The Allies were now ready to increase the pressure. The Amiens area was selected and preparations were made in great secrecy with diversionary activity at other points on the line. 32 divisions were involved (twelve French, eight British, five Australian, four Canadian and one American) supported by over 500 tanks and overwhelming airpower. The first day saw an Allied advance of 5 miles across a 12-mile front, with over 27,000 German casualties. Progress was then less spectacular but by the time the battle ended on August 11 Germany had lost 75,000 men, and suffered a severe blow to morale. Amiens was notable for its successful application of the new combined-arms tactics, fully integrating infantry, artillery, armor and airpower at the commencement of the Allies' final, war-winning offensive. |
