What mathematical modeling uncovers about life in the city X and the City, a book of diverse and accessible math-based topics, uses basic modeling to explore a wide range of entertaining questions about urban life. How do you estimate the number of dental or doctor's offices, gas stations, restaurants, or movie theaters in a city of a given size? How can mathematics be used to maximize traffic flow through tunnels? Can you predict whether a traffic light will stay green long enough for you to cross the intersection? And what is the likelihood that your city will be hit by an asteroid? Every math problem and equation in this book tells a story and examples are explained throughout in an informal and witty style. The level of mathematics ranges from precalculus through calculus to some differential equations, and any reader with knowledge of elementary calculus will be able to follow the materials with ease. There are also some more challenging problems sprinkled in for the more advanced reader. Filled with interesting and unusual observations about how cities work, X and the City shows how mathematics undergirds and plays an important part in the metropolitan landscape.

In this nuanced and groundbreaking history, Donna Murch argues that the Black Panther Party (BPP) started with a study group. Drawing on oral history and untapped archival sources, she explains how a relatively small city with a recent history of African

Containing the proceedings of the 10th International Conference on Urban Regeneration and Sustainability this book addresses the multidisciplinary aspects of urban planning; a result of the increasing size of cities; the amount of resources and services required and the complexity of modern society. Most of earth’s population now lives in cities and the process of urbanisation continues generating many problems deriving from the drift of the population towards them. These problems can be resolved by cities becoming efficient habitats, saving resources in a way that improves the quality and standard of living. The process, however, faces a number of major challenges, related to reducing pollution, improving main transportation and infrastructure systems. New urban solutions are required to optimise the use of space and energy resources leading to improvements in the environment, i.e. reduction in air, water and soil pollution as well as efficient ways to deal with waste generation. These challenges contribute to the development of social and economic imbalances and require the development of new solutions. Large cities are probably the most complex mechanisms to manage. However, despite such complexity they represent a fertile ground for architects, engineers, city planners, social and political scientists, and other professionals able to conceive new ideas and time them according to technological advances and human requirements. The challenge of planning sustainable cities lies in considering their dynamics, the exchange of energy and matter, and the function and maintenance of ordered structures directly or indirectly, supplied and maintained by natural systems. Topics covered include: Urban Strategies; Planning, Development and Management; Urban Conservation and Regeneration; The Community and the City; Eco-town Planning; Landscape Planning and Design; Environmental Management; Sustainable Energy and the City; Transportation; Quality of Life; Architectural Issues; Cultural Heritage Issues; Intelligent Environment and Emerging Technologies; Planning for Risk; Disaster and Emergency Response; Safety and Security; Waste Management; Infrastructure and Society; Urban Metabolism.

'"Relationships in New York are about detachment, so how do you get attached when you decide you want to?" "Honey, you leave town."' Meet Carrie, Miranda, Sam and their stylish friends. Successful, attractive, thirty-something career women living the high life in New York; blazing a glorious cocktail trail from the Bowery Bar to the Baby Doll Lounge; holidaying in the Hamptons and going to Aspen by Lear Jet. But they have more in common than just their enviable lifestyle; they're all searching for lasting love. Finding it is easier said than done in a town full of gorgeous, single, rich men, none of whom want to settle down. Toxic bachelors and serial daters are a perennial problem - but maybe Mr. Big will be different?

This book constitutes the proceedings of the 18th International Conference on Mathematical Optimization Theory and Operations Research, MOTOR 2019, held in Ekaterinburg, Russia, in July 2019. The 48 full papers presented in this volume were carefully reviewed and selected from 170 submissions. MOTOR 2019 is a successor of the well-known International and All-Russian conference series, which were organized in Ural, Siberia, and the Far East for a long time. The selected papers are organized in the following topical sections: mathematical programming; bi-level optimization; integer programming; combinatorial optimization; optimal control and approximation; data mining and computational geometry; games and mathematical economics.
