 Martin Stynes, "Convection Diffusion Problems: An Introduction to Their Analysis and Numerical Solution " English | ISBN: 1470448688 | 2018 | 156 pages | DJVU | 2 MB Many physical problems involve diffusive and convective (transport) processes. When diffusion dominates convection, standard numerical methods work satisfactorily. But when convection dominates diffusion, the standard methods become unstable, and special techniques are needed to compute accurate numerical approximations of the unknown solution. This convection-dominated regime is the focus of the book. After discussing at length the nature of solutions to convection-dominated convection-diffusion problems, the authors motivate and design numerical methods that are particularly suited to this class of problems. At first they examine finite-difference methods for two-point boundary value problems, as their analysis requires little theoretical background. Upwinding, artificial diffusion, uniformly convergent methods, and Shishkin meshes are some of the topics presented. Throughout, the authors are concerned with the accuracy of solutions when the diffusion coefficient is close to zero. Later in the book they concentrate on finite element methods for problems posed in one and two dimensions. This lucid yet thorough account of convection-dominated convection-diffusion problems and how to solve them numerically is meant for beginning graduate students, and it includes a large number of exercises. An up-to-date bibliography provides the reader with further reading.  Controlling Motors with Arduino/Genuino by David Leithauser English | June 15, 2018 | ISBN: 1721143874 | 100 pages | EPUB | 0.98 Mb This book is about controlling motors using Arduinos (called Genuinos outside the United States). I start out with simple direct current (DC) motors, covering turning them on and off, controlling their speed, and reversing direction. I then get into more complicated motors. I discuss two types of stepper motors, a type of precision motor that can be used for detailed control of devices like 3D printers, CNC routers, robot arms, etc. I also discuss servo motors, which are useful for setting positions, and brushless motors, which are good for high speeds like you might need for drone or model plane propellers, fans, model boat propellers, high-speed model cars, and any other application that requires high speeds. This book covers both electronics and programming, so are be electronic schematics and Arduino sketches. I assume that the reader is already familiar with the basics of Arduinos, such as how to install the IDE and load sketches, so I do not go into details on topics like that. I use Arduino Uno as the basis for designs in this book, but other models will work for most of the applications discussed in this book. In the last chapter, I provide several links to locations where you can download the sketches in this book to save you the trouble of typing them.
 Confessions of a Philosopher: A Personal Journey Through Western Philosophy from Plato to Popper By Bryan Magee 1999 | 496 Pages | ISBN: 0375750363 | DJVU | 5 MB In this infectiously exciting book, Bryan Magee tells the story of his own discovery of philosophy and not only makes it come alive but shows its relevance to daily life. Magee is the Carl Sagan of philosophy, the great popularizer of the subject, and author of a major new introductory history, The Story of Philosophy. Confessions follows the course of Magee's life, exploring philosophers and ideas as he himself encountered them, introducing all the great figures and their ideas, from the pre-Socratics to Bertrand Russell and Karl Popper, including Wittgenstein, Kant, Nietzsche, and Schopenhauer, rationalism, utilitarianism, empiricism, and existentialism.
 Sharon Irish, "Concerning Stephen Willats and the Social Function of Art: Experiments in Cybernetics and Society" English | ISBN: 1350197629 | 2021 | 304 pages | PDF | 13 MB This book on Stephen Willats pulls together key strands of his practice and threads them through histories of British cybernetics, experimental art, and urban design. For Willats, a cluster of concepts about control and feedback within living and machine systems (cybernetics) offered a new means to make art relevant.  Computability: A Mathematical Sketchbook By Douglas S. Bridges 2013 | 180 Pages | ISBN: 1461269253 | PDF | 19 MB Aimed at mathematicians and computer scientists who will only be exposed to one course in this area,Computability: AMathematical Sketchbookprovides a brief but rigorous introduction to the abstract theory of computation, sometimes also referred to as recursion theory. It develops major themes in computability theory, such as Rice's theorem and the recursion theorem, and provides a systematic account of Blum's complexity theory as well as an introduction to the theory of computable real numbers and functions. The book is intended as a university text, but it may also be used for self-study; appropriate exercises and solutions are included.  Collaborative circles: friendship dynamics and creative work By Michael P. Farrell 2001 | 328 Pages | ISBN: 0226238660 | PDF | 13 MB Many artists, writers, and other creative people do their best work when collaborating within a circle of likeminded friends. Experimenting together and challenging one another, they develop the courage to rebel against the established traditions in their field. Out of their discussions they develop a new, shared vision that guides their work even when they work alone.In a unique study that will become a rich source of ideas for professionals and anyone interested in fostering creative work in the arts and sciences, Michael P. Farrell looks at the group dynamics in six collaborative circles: the French Impressionists; Sigmund Freud and his friends; C. S. Lewis, J. R. R. Tolkien, and the Inklings; social reformers Elizabeth Cady Stanton and Susan B. Anthony; the Fugitive poets; and the writers Joseph Conrad and Ford Maddox Ford. He demonstrates how the unusual interactions in these collaborative circles drew out the creativity in each member. Farrell also presents vivid narrative accounts of the roles played by the members of each circle. He considers how working in such circles sustains the motivation of each member to do creative work; how collaborative circles shape the individual styles of the persons within them; how leadership roles and interpersonal relationships change as circles develop; and why some circles flourish while others flounder.  Cocaine Confidential By Wensley Clarkson 2014 | 304 Pages | ISBN: 1848663277 | EPUB | 1 MB Cocaine is the world's most notorious narcotic.

 Climate Change: A Very Short Introduction (Very Short Introductions), 4th Edition by Mark Maslin English | October 19th, 2021 | ISBN: 0198867867 | 200 pages | True EPUB | 2.71 MB In the last few years global awareness of climate change has grown very rapidly - through the school strikes led by Greta Thunberg, groups like Extinction Rebellion, the IPCC's recent high impact reports, TV documentaries, and declarations from governments around the world that we are in a climate emergency. This awareness is continuing to grow, as the science shows us that our planet and our species are facing a massive crisis, which we ourselves have caused. Climate change is one of the few scientific theories that make us examine the whole basis of modern society. It is a challenge that has politicians arguing, sets nations against each other, queries individual lifestyle choices, and ultimately asks questions about humanity's relationship with the rest of the planet.  Laura Ugolini, "Civvies: Middle-class men on the English Home Front, 1914-18 " English | ISBN: 1526116669 | 2017 | 352 pages | PDF | 9 MB The history of the First World War continues to attract enormous interest. However, most attention remains concentrated on combatants, creating a misleading picture of wartime Britain: one might be forgiven for assuming that by 1918, the country had become virtually denuded of civilian men and particularly of middle-class men who - or so it seems - volunteered en masse in the early months of war. In fact, the majority of middle-class (and other) men did not enlist, but we still know little about their wartime experiences. Civvies thus takes a different approach to the history of the war and focuses on those middle-class English men who did not join up, not because of moral objections to war, but for other (much more common) reasons, notably age, family responsibilities or physical unfitness. In particular, Civvies questions whether, if serviceman were the apex of manliness, were middle-class civilian men inevitably condemned to second-class, 'unmanly' status? |
