Available in PDF, EPUB and Kindle. Book excerpt: Understanding the dynamics of gauge theories is crucial, given the fact that all known interactions are based on the principle of local gauge symmetry. Beyond the perturbative regime, however, this is a notoriously difficult problem. Requiring invariance under supersymmetry turns out to be a suitable tool for analyzing supersymmetric gauge theories over a larger region of the space of parameters. Supersymmetric quantum field theories in four dimensions with extended N=2 supersymmetry are further constrained and have therefore been a fertile field of research in theoretical physics for quite some time. Moreover, there are far-reaching mathematical ramifications that have led to a successful dialogue with differential and algebraic geometry. These lecture notes aim to introduce students of modern theoretical physics to the fascinating developments in the understanding of N=2 supersymmetric gauge theories in a coherent fashion. Starting with a gentle introduction to electric-magnetic duality, the author guides readers through the key milestones in the field, which include the work of Seiberg and Witten, Nekrasov, Gaiotto and many others. As an advanced graduate level text, it assumes that readers have a working knowledge of supersymmetry including the formalism of superfields, as well as of quantum field theory techniques such as regularization, renormalization and anomalies. After his graduation from the University of Tokyo, Yuji Tachikawa worked at the Institute for Advanced Study, Princeton and the Kavli Institute for Physics and Mathematics of the Universe. Presently at the Department of Physics, University of Tokyo, Tachikawa is the author of several important papers in supersymmetric quantum field theories and string theory.

Book excerpt: An empowering road map for rethinking, reinvigorating, and redesigning our cities, from a pioneer in the movement for safer, more livable streets As New York City's transportation commissioner, Janette Sadik-Khan managed the seemingly impossible and transformed the streets of one of the world's greatest, toughest cities into dynamic spaces safe for pedestrians and bikers. Her approach was dramatic and effective: Simply painting a part of the street to make it into a plaza or bus lane not only made the street safer, but it also lessened congestion and increased foot traffic, which improved the bottom line of businesses. Real-life experience confirmed that if you know how to read the street, you can make it function better by not totally reconstructing it but by reallocating the space that's already there. Breaking the street into its component parts, Streetfight demonstrates, with step-by-step visuals, how to rewrite the underlying "source code" of a street, with pointers on how to add protected bike paths, improve crosswalk space, and provide visual cues to reduce speeding. Achieving such a radical overhaul wasn't easy, and Streetfight pulls back the curtain on the battles Sadik-Khan won to make her approach work. She includes examples of how this new way to read the streets has already made its way around the world, from pocket parks in Mexico City and Los Angeles to more pedestrian-friendly streets in Auckland and Buenos Aires, and innovative bike-lane designs and plazas in Austin, Indianapolis, and San Francisco. Many are inspired by the changes taking place in New York City and are based on the same techniques. Streetfight deconstructs, reassembles, and reinvents the street, inviting readers to see it in ways they never imagined.

Download or read book Right of Way written by Angie Schmitt and published by Island Press. This book was released on 2020-08-27 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The face of the pedestrian safety crisis looks a lot like Ignacio Duarte-Rodriguez. The 77-year old grandfather was struck in a hit-and-run crash while trying to cross a high-speed, six-lane road without crosswalks near his son’s home in Phoenix, Arizona. He was one of the more than 6,000 people killed while walking in America in 2018. In the last ten years, there has been a 50 percent increase in pedestrian deaths. The tragedy of traffic violence has barely registered with the media and wider culture. Disproportionately the victims are like Duarte-Rodriguez—immigrants, the poor, and people of color. They have largely been blamed and forgotten. In Right of Way, journalist Angie Schmitt shows us that deaths like Duarte-Rodriguez’s are not unavoidable “accidents.” They don’t happen because of jaywalking or distracted walking. They are predictable, occurring in stark geographic patterns that tell a story about systemic inequality. These deaths are the forgotten faces of an increasingly urgent public-health crisis that we have the tools, but not the will, to solve. Schmitt examines the possible causes of the increase in pedestrian deaths as well as programs and movements that are beginning to respond to the epidemic. Her investigation unveils why pedestrians are dying—and she demands action. Right of Way is a call to reframe the problem, acknowledge the role of racism and classism in the public response to these deaths, and energize advocacy around road safety. Ultimately, Schmitt argues that we need improvements in infrastructure and changes to policy to save lives. Right of Way unveils a crisis that is rooted in both inequality and the undeterred reign of the automobile in our cities. It challenges us to imagine and demand safer and more equitable cities, where no one is expendable.

Download or read book Engineering Metrology for Pedestrian Falls Prevention and Protection written by In-Ju Kim and published by Springer Nature. This book was released on 2022-03-25 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains how to improve the validity, reliability, and repeatability of slip resistance assessments amongst a range of shoes, floors, and environments from an engineering metrology viewpoint—covering theoretical and experimental aspects of slip resistance mechanics and mechanisms. Pedestrian falls resulting from slips or falls are one of the foremost causes of fatal and non-fatal injuries that limit people’s functionality. There have been prolonged efforts globally to identify and understand their main causes and reduce their frequency and severity. This book deals with large volumes of information on tribological characteristics such as friction and wear behaviours of the shoes and floors and their interactive impacts on slip resistance performances. Readers are introduced to theoretical concepts and models and collected evidence on slip resistance properties amongst a range of shoe and floor types and materials under various ambulatory settings. These approaches can be used to develop secure design strategies against fall incidents and provide a great step forward to build safer shoes, floors, and walking/working environments for industries and communities around the world. The book includes many case studies.

Download or read book Pedestrian Detection Algorithms using Shearlets written by Lienhard Pfeifer and published by Logos Verlag Berlin GmbH. This book was released on 2019-01-15 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we investigate the applicability of the shearlet transform for the task of pedestrian detection. Due to the usage of in several emerging technologies, such as automated or autonomous vehicles, pedestrian detection has evolved into a key topic of research in the last decade. In this time period, a wealth of different algorithms has been developed. According to the current results on pedestrian detection benchmarks, the algorithms can be divided into two categories. First, application of hand-crafted image features and of a classifier trained on these features. Second, methods using Convolutional Neural Networks in which features are learned during the training phase. It is studied how both of these types of procedures can be further improved by the incorporation of shearlets, a framework for image analysis which has a comprehensive theoretical basis. To this end, we adapt the shearlet framework according to the requirements of the practical application of pedestrian detection algorithms. One main application area of pedestrian detection is located in the automotive domain. In this field, algorithms have to be runable on embedded devices. Therefore, we study the embedded realization of a pedestrian detection algorithm based on the shearlet transform.

Download or read book Pedestrian Fall Safety Assessments written by In-Ju Kim and published by Springer. This book was released on 2017-04-25 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines pedestrian shoe-floor slip resistance from an engineering standpoint in order to better understand friction and wear behavior. This analysis includes an extensive investigation into the surface properties of shoes and flow, and the measurement of dynamic friction and other mechanical and physical aspects of shoe-floor tribology. Lastly, the book proposes a measurement concept for the identification and classification of operational floor surfaces under a range of different conditions. Novel techniques and methods are proposed that can improve the reliability of slip resistance assessments. The current state of knowledge is critically examined and discussed from a tribological perspective, including aspects like friction, wear, lubrication and the mechanical behavior of shoes, floors and their wider environment. Further, the book reports on extensive experimental investigations into the topographical characteristics of shoe and floor surfaces and how they affect slip resistance. Slips resulting in pedestrian falls are a major cause of injuries and deaths for all age groups. This important book provides essential insights for researchers, practicing engineers and public safety officials wishing to learn about how the risk of pedestrian slips can be assessed and understood.

Download or read book Transforming Urban Transport written by Diane E. Davis and published by Oxford University Press. This book was released on 2018-10-17 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transforming Urban Transport brings into focus the origins and implementation pathways of significant urban transport innovations that have recently been adopted in major, democratically governed world cities that are seeking to advance sustainability aims. It documents how proponents of new transportation initiatives confronted a range of administrative, environmental, fiscal, and political obstacles by using a range of leadership skills, technical resources, and negotiation capacities to move a good idea from the drawing board to implementation. The book's eight case studies focus on cities of great interest across the globe--Los Angeles, Mexico City, New York, Paris, San Francisco, Seoul, Stockholm, and Vienna--many of which are known for significant mayor leadership and efforts to rescale power from the nation to the city. The cases highlight innovations likely to be of interest to transport policy makers from all corners, such as strengthening public transportation services, vehicle and traffic management measures, repurposing roads and other urban spaces away from their initial function as vehicle travel corridors, and turning sidewalks and city streets into more pedestrian-friendly places for walking, cycling, and leisure. Aside from their transformative impacts in transportation terms, many of the policy innovations examined here have altered planning institutions, public-private sector relations, civil society commitments, and governance mandates in the course of implementation. In bringing these cases to the fore, Transforming Urban Transport advances understanding of the conditions under which policy interventions can expand institutional capacities and governance mandates, particularly linked to urban sustainability. As such, it is an essential contribution to larger debates about what it takes to make cities more environmentally sustainable and the types of strategies and tactics that best advance progress on these fronts in both the short- and the long-term.

Download or read book Queering Criminology written by Matthew Ball and published by Springer. This book was released on 2016-01-26 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Queer criminological work is at the forefront of critical academic criminology, responding to the exclusion of queer communities from criminology, and the injustices that they experience through the criminal justice system. This volume draws together both theoretical and empirical contributions that develop the growing scholarship being produced at the intersection of 'queer' and 'criminology'. Reflecting the diversity of research that is undertaken at this intersection, the contributions to this volume offer a deeper theoretical and conceptual development of this field alongside empirical research that illustrates the continued relevance and urgency of such scholarship. The contributions consider what it means to be queering criminology in the current political, social, and criminological climate, and chart directions along which this field might develop in order to ensure that greater social and criminal justice for LGBTIQ communities is achieved.

Download or read book Smart Planning Sustainability and Mobility in the Age of Change written by Rocco Papa and published by Springer. This book was released on 2018-06-12 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an overview of sustainability and urban mobility in the context of urban planning – topics that are of considerable interest in the development of smart cities. Environmental sustainability is universally recognized as a fundamental condition for any urban policy or urban management activity, while mobility is essential for the survival of complex urban systems. The new opportunities offered by innovations in the mobility of people, goods and information, as well as radically changing interactions and activities are transforming cities. Including contributions by urban planning scholars, the book provides an up-to-date picture of the latest studies and innovative policies and practices in Italy, of particular interest due to its spatial, functional and social peculiarities. Sustainability and mobility must form the basis of “smart planning” – a new dimension of urban planning linked to two main innovations: procedural innovation in the management of territorial transformations and the technological innovation of the generation, processing and distribution of data (big data) for the creation of new "digital environments" such as GIS, BIM, models of augmented and mixed reality, useful for describing changes in human settlement in real time.
