Free Download The Bio-inspired X-Structure/Mechanism Approach for Exploring Nonlinear Benefits in Engineering: Part I-Nonlinear Stiffness and Nonlinear Damping by Xingjian Jing English | PDF EPUB (True) | 2024 | 407 Pages | ISBN : 9819734916 | 138.5 MB This book presents a unique approach to the design and analysis of beneficial nonlinearity, which can take an important and critical role in engineering systems and thus cannot be simply ignored in structural design, dynamic response analysis, and parameter selection. A key issue in the area is thus systematically addressed about how to analyze and design potential nonlinearities introduced to or inherent in a system, which is a must-do task in many practical applications involving vibration control, energy harvesting, sensor systems and robots, etc. This book, therefore, presents an up-to-date summary on the most recent development of a cutting-edge method for nonlinearity manipulation and employment developed in recent several years, known as the X-shaped structure or mechanism approach. The method is inspired from animal leg/limb skeletons and can provide passive low-cost high-efficiency adjustable and beneficial nonlinear stiffness (high static and ultra-low dynamic), nonlinear damping (dependent on resonant frequency and vibration excitation amplitude), and nonlinear inertia (low static and high dynamic) individually or simultaneously. The X-shaped structure or mechanism is a generic structure or mechanism representing a class of beneficial geometric nonlinearity with realizable and flexible linkage mechanism or structural design of different variants or forms (quadrilateral, diamond, polygon, K/Z/S/V/A/W-shape, or others) which all share similar geometric nonlinearity and thus similar nonlinear stiffness/damping properties, flexible in design, and easy to implement.  Free Download The Beauty of Doing Mathematics: Three Public Dialogues by Serge Lang English | PDF | 1985 | 133 Pages | ISBN : 0387961496 | 10.7 MB If someone told you that mathematics is quite beautiful, you might be surprised. But you should know that some people do mathematics all their lives, and create mathematics, just as a composer creates music. Usually, every time a mathematician solves a problem, this gives rise to many oth ers, new and just as beautiful as the one which was solved. Of course, often these problems are quite difficult, and as in other disciplines can be understood only by those who have studied the subject with some depth, and know the subject well. In 1981, Jean Brette, who is responsible for the Mathematics Section of the Palais de la Decouverte (Science Museum) in Paris, invited me to give a conference at the Palais. I had never given such a conference before, to a non-mathematical public. Here was a challenge: could I communicate to such a Saturday afternoon audience what it means to do mathematics, and why one does mathematics? By "mathematics" I mean pure mathematics. This doesn't mean that pure math is better than other types of math, but I and a number of others do pure mathematics, and it's about them that I am now concerned. Math has a bad reputation, stemming from the most elementary levels. The word is in fact used in many different contexts. First, I had to explain briefly these possible contexts, and the one with which I wanted to deal.

Free Download The Audit Failures of the Wirecard Scandal: Examining the Role of the Auditor in Regulatory Oversight by Edgar Löw , Reinhard Heyd English | PDF EPUB (True) | 2024 | 185 Pages | ISBN : 3031598539 | 8.8 MB Wirecard was the largest economic scandal in the history of Germany. Following the collapse of Wirecard, numerous lawsuits, both criminal and civil by equity and debt investors, were filed not only against Wirecard but also against the auditor Ernst & Young. This book demonstrates that a proper audit in accordance with the auditing standards would have uncovered the fraud much earlier, and details what went wrong. The book first deals with the fundamentals of auditing and examines the Wirecard business models from a legal and economic perspective. Then, the book deals with the fiduciary structure, which there has been often debated. When the fraud was uncovered, it became clear that 1.9 billion Euros that were supposed to be in escrow accounts were not. The book discusses the balance sheet mapping in detail, including the related audit requirements and examines in which balance sheet item the amounts (allegedly) in escrow accounts should have been reported, before examining and weighing the corresponding income statement items. In each chapter, not only are the accounting requirements presented, but the requirements for audit measures based on the respective Standards on Auditing are highlighted and explained in detail. The book places the requirements for reporting in the context of the Wirecard case, and will be of interest to accountants, auditors, market regulators, and credit risk analysts alongside students of accounting/auditing.

Free Download The Arabic Version of Euclid's Optics: Edited and Translated with Historical Introduction and Commentary Volume I by Elaheh Kheirandish English | PDF | 1999 | 309 Pages | ISBN : 0387985239 | 14.9 MB Like all classical Greek texts on science, Euclid's works on optics initially came to the West mainly through medieval Arabic texts and commentaries. While several Greek versions of the Optika were discovered and translated as early as the sixteenth century, sorting out what may have been Euclid's original has not been easy. This book presents a critical translation of an Arabic texts and of Arabic commentaries on the text, and places the whole in a historical context. The Optics is particularly interesting in that Euclid's text was considerably transformed in the process of translation into Arabic "equivalents"; in addition, several of the Arabic editions of Euclid's text (c. 300 BC) contained liberal admixtures of a much later book by Ptolemy (c. 200 AD) of the same title. What was referred to as "Euclid's Optics," the "Kitab Uqlidis fi Ikhtilaf al-manazir," thus became as much an exposition of an Arabic version of a visual theory as a translation of Euclid's ideas on the subject. In preparing this edition, Dr. Kheirandish has thus not only sorted out the various manuscript versions of Al-Manazir, but also related and unrelated texts that were often confused with it.  Free Download The Almonds and Related Species: Identification, Characteristics and Uses by Alireza Rahemi , Thomas M. Gradziel English | PDF EPUB (True) | 2024 | 199 Pages | ISBN : 3031589378 | 54.4 MB Almond and peach species have global importance as food crops as well as use in landscaping including restoration and reforestation. Because currently available breeding germplasm has a very narrow genetic base, genetic improvement programs are turning to wild germplasm as sources of improved quality, productivity and resistance traits. This germplasm is also enabling the dramatic modification of traditional cropping systems as with the transfer of self-fruitfulness from related wild almond and peach species to normally self-sterile cultivated almond. While presence of an extensive wild almond and related germplasm has been documented in the literature over the past century, most information remains dispersed and often not generally accessible owing to its publication in treatises and journals of limited distribution.This monograph brings together a comprehensive characterization of almond and its related species including the cultivated and wild peaches. Because it represents the only comprehensive source of information on almond, peach and their wild relatives, it represents a basic reference text of interest to researchers in both the basic and applied plant and ecological sciences.
