Is Canada Even Real?

Is Canada Even Real?

This quirky ode to a quirky land is a humorous nostalgia trip and a fun Canadian history lesson couched in a hipster quiz book. If you’ve ever wonderedWhy is the inuksuk more revered than Wheelchair Jimmy?Does the iconic beaver really represent us better than The Littlest Hobo?Is everyone going canoeing without me or is canoeing way less of a thing than it’s made out to be? then this book is for you. Is Canada even real? It’s a question that’s being asked more and more, thanks to our waterproof, see-through, supposedly maple-scented currency and our improbably hot prime minister’s assertion that Santa lives here.In the age of Google Maps and #factcheck, how could the existence of Canada be questioned? And yet how could a nation that’s the home of toboggans, Drake, and KD exist in the same realm as, say, Belgium or Niger? Is Canada Even Real? examines the cultural factors behind the twenty-first-century monolithic myth of Canada, a nation that is lovable and real — if only in your imagination.
Banded Vegetation Patterning in Arid and Semiarid Environments

Banded Vegetation Patterning in Arid and Semiarid Environments

Aerial photography has revealed the striking, widespread phenomenon of repeating patterns of vegetation in more arid areas of the world. Two interdependent phases, bands of dense and sparse vegetation, alternate in the landscape. This volume synthesizes half a centurys accumulated knowledge of both theoretical and applied landscape functions from a variety of these regions. It covers structure, dynamics, and methods of study, as well as disturbances to these landscapes and relevant management issues. Chapters are included to discuss the role of modeling in answering questions about the origins and complex processes of banded landscapes. Studies of banded landscapes have yielded valuable lessons for understanding other semi-arid landscapes as well, leading to a knowledge base facilitating sustainable use and rehabilitation.

Numerical Semigroups

Let N be the set of nonnegative integers. A numerical semigroup is a nonempty subset S of N that is closed under addition, contains the zero element, and whose complement in N is ?nite. If n ,...,n are positive integers with gcd{n ,...,n } = 1, then the set hn ,..., 1 e 1 e 1 n i = {? n +··· + ? n | ? ,...,? ? N} is a numerical semigroup. Every numer e 1 1 e e 1 e ical semigroup is of this form. The simplicity of this concept makes it possible to state problems that are easy to understand but whose resolution is far from being trivial. This fact attracted several mathematicians like Frobenius and Sylvester at the end of the 19th century. This is how for instance the Frobenius problem arose, concerned with ?nding a formula depending on n ,...,n for the largest integer not belonging to hn ,...,n i (see [52] 1 e 1 e for a nice state of the art on this problem).
Ancient Earth Mysteries

Ancient Earth Mysteries

Is humanity the first creation of intelligent beings? Do similar human-type species exist throughout the cosmos? If so, have those species mastered technologies only to self-destruct in an unfortunate series of events? The Universe is unbelievably enormous, this is undisputed. It's extremely selfish to think we are the only existing intelligent life. Science and religion are on the verge of discovering the truth. Super ancient societies and their archaeological evidence uncovered to this day is a vault of stored information waiting to be unlocked. All we need to do is find the key. Help us uncover the truth by learning about Ancient Earth Mysteries.Evidence suggests: "Humanity is not the first nor will be the last creation of intelligent beings. Perhaps millions of years ago a similar species existed which mastered technologies only to face its own demise by an unfortunate series of events. Maybe remnants of super ancient societies are mixed in with the archaeological evidence uncovered to this day. The results could be confusing us further when trying to solve the riddle of our past for this reason. If evolution evolved once, it seems likely evolution has evolved before in other ways as it continues to evolve simultaneously on other worlds. "
Verifying Temporal Properties of Systems

Verifying Temporal Properties of Systems

This monograph aims to provide a powerful general-purpose proof tech­ nique for the verification of systems, whether finite or infinite. It extends the idea of finite local model-checking, which was introduced by Stirling and Walker: rather than traversing the entire state space of a model, as is done for model-checking in the sense of Emerson, Clarke et ai. (checking whether a (finite) model satisfies a formula), local model-checking asks whether a particular state satisfies a formula, and only explores the nearby states far enough to answer that question. The technique used was a tableau method, constructing a tableau according to the formula and the local structure of the model. This tableau technique is here generalized to the infinite case by considering sets of states, rather than single states; because the logic used, the propositional modal mu-calculus, separates simple modal and boolean connectives from powerful fix-point operators (which make the logic more expressive than many other temporal logics), it is possible to give a rela­ tively straightforward set of rules for constructing a tableau. Much of the subtlety is removed from the tableau itself, and put into a relation on the state space defined by the tableau-the success of the tableau then depends on the well-foundedness of this relation. The generalized tableau technique is exhibited on Petri nets, and various standard notions from net theory are shown to playa part in the use of the technique on nets-in particular, the invariant calculus has a major role.
Control of Human Voluntary Movement

Control of Human Voluntary Movement

J.C. Rothwell

The human motor system is unique. It talks, walks and can play the piano from a remarkably early age. But it is difficult to study. One cannot impale single neurones with electrodes or lesion discrete areas of the nervous system in man. However, data gleaned from such elegant experiments in lower species that walk on four feet may not reflect the organisation of human motor mechanisms. John Rothwell is one of a small band of human-motor physiologists who have followed the dictum 'The proper study of mankind is man'. In this book, he brings together what is known about human motor physiology in an eminently readable and critical fashion. Of course, there is a stimulating symbiosis between animal and human experimental motor physiology, and this is effected by the integration of critical information that can only be obtained from work on animals with what is known about man. Many disciplines have interest in the mechanisms of human voluntary movement - physiologists, psychologists, physiotherapists and clinicians, be they neurologists or those working in orthopaedics, physical medicine or rehabilitation. All will find John Rothwell's book invaluable. To the beginner it provides an excellent introduction to the subject. To the expert it presents a coherent review of current knowledge and areas of uncertainty. What is abundantly clear is how much more remains to be discovered about how man controls movement. The stimulus provided by this volume will be invaluable to thought and experiment.

Mathematics is playing an ever more important role in the physical and biological sciences, provoking a blurring of boundaries between scientific disciplines and a resurgence of interest in the modem as well as the classical techniques of applied mathematics. This renewal of interest,both in research and teaching, has led to the establishment of the series: Texts in Applied Mathematics (TAM). The developmentof new courses is a natural consequenceof a high level of excite­ ment on the research frontier as newer techniques, such as numerical and symbolic computersystems,dynamicalsystems,and chaos, mix with and reinforce the tradi­ tional methods of applied mathematics. Thus, the purpose of this textbook series is to meet the current and future needs of these advances and encourage the teaching of new courses. TAM will publish textbookssuitable for use in advancedundergraduate and begin­ ning graduate courses, and will complement the Applied Mathematical Seiences (AMS) series, which will focus on advanced textbooks and research level mono­ graphs. Preface Tbe purpose of this preface is twofold. Firstly, to give an informal historical in­ troduction to the subject area of this book, Systems and Control , and secondly, to explain the philosophy of the approach to this subject taken in this book and to outline the topics that will be covered.
Computational Inelasticity

This book goes back a long way. There is a tradition of research and teaching in inelasticity at Stanford that goes back at least to Wilhelm Flugge ¨ and Erastus Lee. I joined the faculty in 1980, and shortly thereafter the Chairman of the Applied Mechanics Division, George Herrmann, asked me to present a course in plasticity. I decided to develop a new two-quarter sequence entitled “Theoretical and C- putational Plasticity” which combined the basic theory I had learned as a graduate student at the University of California at Berkeley from David Bogy, James Kelly, Jacob Lubliner, and Paul Naghdi with new computational techniques from the ?nite-element literature and my personal research. I taught the course a couple of times and developed a set of notes that I passed on to Juan Simo when he joined thefacultyin1985. IwasChairmanatthattimeandIaskedJuantofurtherdevelop the course into a full year covering inelasticity from a more comprehensive p- spective. Juan embarked on this path creating what was to become his signature course. He eventually renamed it “Computational and Theoretical Inelasticity” and it covered much of the material that was the basis of his research in material modeling and simulation for which he achieved international recognition. At the outset we decided to write a book that would cover the material in the course.
