This book gathers a selection of refereed papers presented at the “International Conference on Operations Research OR2015,” which was held at the University of Vienna, Austria, September 1-4, 2015. Over 900 scientists and students from 50 countries attended this conference and presented more than 600 papers in parallel topic streams as well as special award sessions. Though the guiding theme of the conference was “Optimal Decision and Big Data,” this volume also includes papers addressing practically all aspects of modern Operations Research.

A concise, modern textbook on group theory written especially for physicists Although group theory is a mathematical subject, it is indispensable to many areas of modern theoretical physics, from atomic physics to condensed matter physics, particle physics to string theory. In particular, it is essential for an understanding of the fundamental forces. Yet until now, what has been missing is a modern, accessible, and self-contained textbook on the subject written especially for physicists. Group Theory in a Nutshell for Physicists fills this gap, providing a user-friendly and classroom-tested text that focuses on those aspects of group theory physicists most need to know. From the basic intuitive notion of a group, A. Zee takes readers all the way up to how theories based on gauge groups could unify three of the four fundamental forces. He also includes a concise review of the linear algebra needed for group theory, making the book ideal for self-study. Provides physicists with a modern and accessible introduction to group theory Covers applications to various areas of physics, including field theory, particle physics, relativity, and much more Topics include finite group and character tables; real, pseudoreal, and complex representations; Weyl, Dirac, and Majorana equations; the expanding universe and group theory; grand unification; and much more The essential textbook for students and an invaluable resource for researchers Features a brief, self-contained treatment of linear algebra An online illustration package is available to professors Solutions manual (available only to professors)

When Ozzie Nelson died in 1975, he was no longer a household name. For a guy who had created the longest-running TV sitcom in history, invented the rock video, and fronted one of the most successful big bands of the 1930s, it's baffling that Nelson has faded so far from American media memory. Larger than life offscreen--an attorney, college football star, cartoonist, songwriter, major band leader--Ozzie created a smaller-than-life TV persona, the bumbling average Dad who became known to the rock generation (which included his teen idol son Rick Nelson) as the essence of blandness. But America also saw Ozzie as their iconic Dad: not a "father knows best," since his pontifications usually proved flawed by the end of each episode, but the father who tried his best. This book is the only full-length biography of Ozzie Nelson since he published his memoirs in 1973. It treats the big band and early TV icon with affection and hints that American pop culture may owe more to Ozzie than is generally acknowledged.

National architectural magazine now in its fifteenth year, covering period-inspired design 1700–1950. Commissioned photographs show real homes, inspired by the past but livable. Historical and interpretive rooms are included; new construction, additions, and new kitchens and baths take their place along with restoration work. A feature on furniture appears in every issue. Product coverage is extensive. Experts offer advice for homeowners and designers on finishing, decorating, and furnishing period homes of every era. A garden feature, essays, archival material, events and exhibitions, and book reviews round out the editorial. Many readers claim the beautiful advertising—all of it design-related, no “lifestyle” ads—is as important to them as the articles.

The progressive "netroots," fueled by bloggers writing on websites like the Daily Kos and working through online organizations like MoveOn, are on the verge of spearheading a revolution that may well define the coming political era. Still, their purpose, goals, and track record remain largely misunderstood. This book provides an understanding of the loosely affiliated groups that collectively call themselves the progressive netroots: who they are, what they hope to accomplish, what they've done so far and how likely it is they will succeed in a plan so audacious it would result, if realized, in the transformation of America from a television-focused, center-right nation to an Internet-focused, center-left nation. Netroots weaves together a range of evidence and arguments to shatter conventional myths about this online movement. It explains why the left is better positioned than the right to take advantage of the decentralized nature of the Internet. As progressive candidates make uneven progress toward winning elections, the progressive netroots are working to drive media narratives and building real and virtual communities of activists that will contribute strongly to electoral success. Netroots documents the achievements of this emerging political force through an engaging analysis told with an eye toward history and in the bloggers' own words.
