Free Download Martin W Bowman, "The Men Who Flew the English Electric Lightning" English | 2021 | ISBN: 1526705648 | EPUB | pages: 288 | 4.4 mb The early 1950s were a boom time for British aviation. The lessons of six years of war had been learned and much of the research into jet engines, radar and aerodynamics had begun to reach fruition. In Britain, jet engine technology led the world, while wartime developments into swept wing design in Germany and their transonic research program were used to give western design teams a quantum leap in aircraft technology. At English Electric, 'Teddy' Petter's design team were keen to capitalize on the success of their Canberra jet bomber and rose to the challenge of providing a high speed interceptor for the RAF.  Free Download The Memory of Trees: The future of eucalypts and our home among them by Viki Cramer English | June 27, 2023 | ISBN: 1760762369 | True EPUB | 344 pages | 1.6 MB Most Australians see their world through eucalypts. From towering forests to straggly woodlands, in city parks, by the coast and in the bush, these are the trees that inhabit our familiar landscapes and national psyche. Yet the resilience of our eucalypt ecosystems is being tested by logging and land clearing, disease and drought, fire and climate change. In many places they are a faded remnant of those known by past generations. How important is the memory of these trees?  Free Download Thomas Gregor, "The Mehinaku: The Drama of Daily Life in a Brazilian Indian Village" English | 1980 | ISBN: 0226307468, 0226307441 | EPUB | pages: 398 | 4.2 mb Thomas Gregor sees the Mehinaku Indians of central Brazil as performers of roles, engaged in an ongoing improvisational drama of community life. The layout of the village and the architecture of the houses make the community a natural theater in the round, rendering the villagers' actions highly visible and audible. Lacking privacy, the Mehinaku have become masters of stagecraft and impression management, enthusiastically publicizing their good citizenship while ingeniously covering up such embarrassments as extramarital affairs and theft.  Free Download The Medieval Risk-Reward Society: Courts, Adventure, and Love in the European Middle Ages (Interventions: New Studies Medieval Culture) by Will Hasty English | March 29, 2016 | ISBN: 0814213030, 0814252656 | True PDF | 312 pages | 2.5 MB The Medieval Risk-Reward Society offers a study of adventure and love in the European Middle Ages focused on the poetry of authors such as Marie de France, Chrétien de Troyes, Wolfram von Eschenbach, and Gottfried von Strassburg-showing how a society based on sacrifice becomes a society based on wagers and investments. Will Hasty's sociological approach to medieval courtly literature, informed by the analytic tools of game theory, reveals the blossoming of a worldview in which outcomes are uncertain, such that the very self (of a character or an authorial persona) is contingent on success or failure in possessing the things it desires-and upon which its social identity and personal happiness depend. Drawing on a diverse selection of contrasting canonical works ranging from the Iliad to the biblical book of Joshua to High Medieval German political texts to the writings of Leibniz and Mark Twain, Hasty enables an appreciation of the distinctive contributions made in antiquity and the Middle Ages to the medieval emergence of a European society based on risks and rewards.  Free Download Heß, "The Medieval Archive of Antisemitism in Nineteenth-Century Sweden " English | ISBN: 3110673436 | 2021 | 220 pages | EPUB, PDF | 4 MB + 2 MB The significance of religion for the development of modern racist antisemitism is a much debated topic in the study of Jewish-Christian relations. This book, the first study on antisemitism in nineteenth-century Sweden, provides new insights into the debate from the specific case of a country in which religious homogeneity was the considered ideal long into the modern era.  Free Download The Maverick Effect: The Inside Story of a Movement that Shaped India's IT Revolution by Harish Mehta English | November 30, 2022 | ISBN: 9354895298 | 295 pages | PDF | 5.09 Mb 'The customs officer told me that I needed to leave samples of what I was exporting with him. I was forced to leave the floppy disk of the software with him. The diligent officer immediately planted a stapler pin through the floppy disk and attached it to the form, thereby destroying the media and rendering it unreadable. For the longest time, everybody's understanding of software differed immensely. This confusion continued into the 1980s, and it was getting challenging to grow the business. The more I met young software entrepreneurs, the more I realized that my frustration was not unique. Something had to be done.' In the mid-1970s, a young, twenty-something man living an American dream threw away a lucrative job as a database manager and came back to India. At that time, India had no IT industry to speak of; computers were a novelty, and the nation was trapped in socio-economic backwardness and a labyrinthine License Raj. As young Harish Mehta struggled to find his stride, he realized that India's nascent and fragmented IT industry acutely needed a unified voice that could speak to the government, change laws and harness the country's potential. In an unlikely alliance of headstrong and competing young professionals, he united other IT entrepreneurs to envision a world-beating association that would revolutionize Indian IT: NASSCOM. The Maverick Effect is the extraordinary story of this band of dreamers who joined hands to transform a nation while also changing the lens through which the world looked at India. Valued at a staggering $200 billion today, the Indian IT industry directly employs more than four million people. It is the largest forex earner and has helped millions of Indians beat poverty and rise to the middle-income group. Honest, open and inspiring, Harish Mehta's journey proves that no vision is impossible if unrelenting, kindred spirits unite.  Free Download The Mathematics of Music and Art English | 2023 | ISBN: 3031344391 | 202 Pages | PDF EPUB (True) | 27 MB This book explores the relationships between music, the sciences, and mathematics, both ancient and modern, with a focus on the big picture for a general audience as opposed to delving into very technical details. The language of music is deciphered through the language of mathematics. Readers are shown how apparently unrelated areas of knowledge complement each other and in fact propel each other's advancement. The presentation as well as the collection of topics covered throughout is unique and serves to encourage exploration and also, very concretely, illustrates the cross- and multidisciplinary nature of knowledge. Inspired by an introductory, multidisciplinary course, the author explores the relationships between the arts, sciences, and mathematics in the realm of music. The book has no prerequisites; rather it aims to give a broad overview and achieve the integration of the three presented themes. Mathematical tools are introduced and used to explain various aspects of music theory, and the author illustrates how, without mathematics, music could not have been developed.  Free Download The Mathematics of Internet Congestion Control by R. Srikant English | PDF | 2004 | 170 Pages | ISBN : 0817632271 | 10.8 MB Congestion control algorithms were implemented for the Internet nearly two decades ago, but mathematical models of congestion control in such a large-scale network are relatively new. This text presents models for the development of new protocols that can help make Internet data transfers virtually loss- and delay-free. Introduced are tools from optimization, control theory, and stochastic processes integral to the study of congestion control algorithms.Intended for graduate students and researchers in systems theory and computer science, the text assumes basic knowledge of first-year, graduate-level control theory, optimization, and stochastic processes, but the key prerequisites are summarized in an appendix for quick reference. The work's wide range of applications to the study of both new and existing protocols and control algorithms make the book of interest to researchers and students concerned with many aspects of large-scale information flow on the Internet.  Free Download James Coleman, "The Mathematics of Collective Action" English | 2005 | ISBN: 0202307905, 1138536725 | EPUB | pages: 191 | 4.3 mb Philosophers, social scientists, and laymen have used two perspectives in analyzing social action. One sees man's action as the result of causal forces, and the other sees action as purposive and goal directed. Mathematical treatment of social action has shown this same dichotomy. Some models of behavior describe a causal process, in which there is no place for intention or purpose. Most stochastic models of behavior, whether individual or group, are like this. Another body of work, however, employs purpose, anticipation of some future state, and action designed to maximize the proximity to some goal. Classical microeconomic theory, statistical decision theory, and game theory exemplify this direction.This book examines these two directions of work, and makes original contributions to the second. An introductory chapter outlines these two bodies of work, and casts them in a common frame, to display their similarities and differences. Chapter 2 reviews at length recent work in stochastic processes that makes up the first body of work, which sees social action as the resultant of causal forces. The remaining chapters develop a mathematical framework for the study of systems of social action using a purposive theoretical base. These chapters are designed particularly to contribute to the study of collective decisions, a form of social action that has proved particularly challenging to theoretical analysis. First published in 1973, this became a significant work both in problem solving and in the future career of the author. It is of continuing importance to researchers and students interested in statistical analysis.
