Book excerpt: Le domaine de l'étude est celui de l'interaction d'une onde électromagnétique avec une interface 2D (caractérisée par z = S(x,y)) séparant deux milieux linéaires, homogènes, et isotropes. L'essentiel du travail consiste en l'introduction de trois méthodes originales de calcul du champ diffusé par des surfaces rugueuses aléatoires. La première méthode est une simulation numérique basée sur une méthode itérative de calcul des développements en ondes planes des champs réfléchi et transmis. Cette technique est mise en œuvre numériquement (code diff3d) pour des surfaces 1D et 2D. Elle est validée dans le cas 1D par comparaison avec une méthode intégrale de référence. La deuxième méthode effectue un développement limite d'un opérateur de diffusion à l'ordre 2 en la hauteur de la surface, et fournit un résultat perturbatif renormalisé. La troisième méthode utilise des techniques de régularisation pour proposer un résultat sans effectuer de développement perturbatif. Les deux méthodes approchées précédentes, ainsi que l'approximation classique de l'optique physique, font l'objet d'une validation par comparaison avec diff3d, utilise comme référence dans le cas des surfaces bidimensionnelles. L'influence des paramètres du problème (caractéristiques de la rugosité et du rayonnement incident) sur les champs cohérents réfléchi et transmis est explorée pour une surface en verre, éclairée dans le visible. Les hypothèses, qui doivent être satisfaites, et des précautions, qu'il convient de prendre, pour pouvoir simuler numériquement le phénomène de diffusion d'un rayonnement par une surface rugueuse aléatoire, sont recensées. Les déformations subies par un faisceau gaussien lors de sa réflexion sur une interface sont étudiées. Ces effets, connus sous le nom d'effets non spéculaires, ont été précédemment présentés en 1D. L'extension au cas 2D nous permet de mettre en évidence un nouvel effet : l'astigmatisme de la réflexion par un dioptre plan.

Book excerpt: Toronto has over 600 public outdoor sculptures, works of art that provide a sense of the rich variety of life and work in the city, its peoples, cultures and aspirations. Interest in commissioning public sculpture began slowly in the nineteenth and early twentieth century, but increased rapidly after the 1950s.This is a book about the sculptures and how they disclose the city to itself. Creating Memory’s two introductory sections examine the factors behind this expansion over time and the changes in style as one generation of sculptors succeeded another. It looks at the reasons behind the changes as sculptures were conceived, sculpted and erected. More than 10 categories of sculptures are defined and discussed, including Founding the City, Natural Environment, Immigration, Ethnic Groups, Economic Activities, Disaster and Calamity, War And Conflict, Leaders, Ordinary Citizens, Community Life, and Works of the Imagination.

Book excerpt: Featuring more than 500 public art installations, this is the first comprehensive guidebook to explore Vancouver's urban treasures. The character of a city is revealed by the public art that neighborhoods and residents collectively place on streets and walls and in their public spaces. As a city known internationally for its breathtaking cityscapes and mountain backdrop, Vancouver has much to offer visually including the diverse and thriving public art in the city's neighborhoods. Engaging color photos and detailed descriptions that focus on the historical and cultural context of each art piece, its place in modern art and the artist who created it allow for a greater understanding of these urban treasures. Easy-to follow maps take readers to communities and destinations such as False Creek, Chinatown, the West End, Downtown, East Vancouver, VanDusen Garden, Stanley Park and the University of British Columbia. Tour the better known and the unknown art installations that are made from every possible media and include monuments, paintings, murals, tapestries, figures, First Nations art, relics, busts, fountains, gateways, mosaics, sculptures and reliefs.

Available in PDF, EPUB and Kindle. Book excerpt: Arguably, public art is experienced daily by more people than most offerings in galleries, yet our notion of what constitutes public art is surprisingly limited. Public Art in Canada broadens the critical discussion by exploring public art's varied means of engaging with public space and the public sphere. Annie Gérin and James S. McLean have assembled contributions from new and established Canadian scholars, curators, and artists. Each contributor enlivens our understanding of public art as a practice and its place in the social and aesthetic formation of which it is a part. As a result, the book provides an overview of the current debates in the field of public art that are informed by the theories and critical literature of art history, communication studies, cultural studies, sociology, and urban studies. The rigorous essays and original works of art collected in this volume present a compelling demonstration of the strategies, aesthetic and otherwise, used by artists to elicit intellectual, sensual, or emotional responses that can only be obtained through artistic practices in public places. Public Art in Canada is a major contribution to the study of Canadian art and culture.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental results and analyses are given in this report on bridge abutment scour in compound channels. Experiments were conducted in a laboratory flume with a cross section consisting of a wide floodplain adjacent to a main channel. The embankment length, discharge, sediment size, and abutment shape were varied, and the resulting equilibrium scour depths were measured. Water-surface profiles, velocities, and scour-hole contours were also measured. In the report, a methodology is developed for estimating abutment scour that takes into account the redistribution of discharge in the bridge contraction, abutment shape, sediment size, and tailwater depth. The independant variables in the proposed scour formula are evaluated at the approach-channel cross section and can be obtained froma one-dimensional water-surface profile computer program such as the Water-Surface Profile Program (WSPRO). The proposed scour evaluation procedure is outlined and illustrated, including consideration of the time required to reach equilibrium scour. The proposed methodology is applied to two cases of measured scour in the field.

Book excerpt: This is the third Selecta of publications of Elliott Lieb, the first two being Stabil ity of Matter: From Atoms to Stars, edited by Walter Thirring, and Inequalities, edited by Michael Loss and Mary Beth Ruskai. A companion fourth Selecta on Statistical Mechanics is also edited by us. Elliott Lieb has been a pioneer of the discipline of mathematical physics as it is nowadays understood and continues to lead several of its most active directions today. For the first part of this selecta we have made a selection of Lieb's works on Condensed Matter Physics. The impact of Lieb's work in mathematical con densed matter physics is unrivaled. It is fair to say that if one were to name a founding father of the field, Elliott Lieb would be the only candidate to claim this singular position. While in related fields, such as Statistical Mechanics and Atomic Physics, many key problems are readily formulated in unambiguous mathematical form, this is less so in Condensed Matter Physics, where some say that rigor is "probably impossible and certainly unnecessary". By carefully select ing the most important questions and formulating them as well-defined mathemat ical problems, and then solving a good number of them, Lieb has demonstrated the quoted opinion to be erroneous on both counts. What is true, however, is that many of these problems turn out to be very hard. It is not unusual that they take a decade (even several decades) to solve.

Book excerpt: This is the first economics work of its kind offering the economist the opportunity to acquire new and important analytical tools. It introduces the reader to three advanced mathematical methods by presenting both their theoretical bases and their applications to a wide range of economic models. The mathematical methods presented are ordinary differential equations, stability techniques and chaotic dynamics. Topics such as existence, continuation of solutions, uniqueness, dependence on initial data and parameters, linear systems, stability of linear systems, two dimensional phase analysis, local and global stability, the stability manifold, stability of optimal control and empirical tests for chaotic dynamics are covered and their use in economic theory is illustrated in numerous applications. These applications include microeconomic dynamics, investment theory, macroeconomic policies, capital theory, business cycles, financial economics and many others. All chapters conclude with two sections on miscellaneous applications and exercises and further remarks and references. In total the reader will find a valuable guide to over 500 selected references that use differential equations, stability analysis and chaotic dynamics. Graduate students in economics with a special interest in economic theory, economic researchers and applied mathematicians will all benefit from this volume.

Available in PDF, EPUB and Kindle. Book excerpt: We all talk about the "tube" or "box," as if television were simply another appliance like the refrigerator or toaster oven. But Cecilia Tichi argues that TV is actually an environment--a pervasive screen-world that saturates almost every aspect of modern life. In Electronic Hearth, she looks at how that environment evolved, and how it, in turn, has shaped the American experience. Tichi explores almost fifty years of writing about television--in novels, cartoons, journalism, advertising, and critical books and articles--to define the role of television in the American consciousness. She examines early TV advertising to show how the industry tried to position the new device as not just a gadget but a prestigious new piece of furniture, a highly prized addition to the home. The television set, she writes, has emerged as a new electronic hearth--the center of family activity. John Updike described this "primitive appeal of the hearth" in Roger's Version: "Television is--its irresistible charm--a fire. Entering an empty room, we turn it on, and a talking face flares into being." Sitting in front of the TV, Americans exist in a safety zone, free from the hostility and violence of the outside world. She also discusses long-standing suspicions of TV viewing: its often solitary, almost autoerotic character, its supposed numbing of the minds and imagination of children, and assertions that watching television drugs the minds of Americans. Television has been seen as treacherous territory for public figures, from generals to presidents, where satire and broadcast journalism often deflate their authority. And the print culture of journalism and book publishing has waged a decades-long war of survival against it--only to see new TV generations embrace both the box and the book as a part of their cultural world. In today's culture, she writes, we have become "teleconscious"--seeing, for example, real life being certified through television ("as seen on TV"), and television constantly ratified through its universal presence in art, movies, music, comic strips, fabric prints, and even references to TV on TV. Ranging far beyond the bounds of the broadcast industry, Tichi provides a history of contemporary American culture, a culture defined by the television environment. Intensively researched and insightfully written, The Electronic Hearth offers a new understanding of a critical, but much-maligned, aspect of modern life.
