This book constitutes the refereed proceedings of the 13th International Conference on Integer Programming and Combinatorial Optimization, IPCO 2008, held in Bertinoro, Italy, in May 2008. The 32 revised full papers presented were carefully reviewed and selected from 95 submissions. The papers cover various aspects of integer programming and combinatorial optimization and present recent developments in theory, computation, and applications in that area. Topics included are such as approximation algorithms, branch and bound algorithms, branch and cut algorithms, computational biology, computational complexity, computational geometry, cutting plane algorithms, diophantine equations, geometry of numbers, graph and network algorithms, integer programming, matroids and submodular functions, on-line algorithms and competitive analysis, polyhedral combinatorics, randomized algorithms, random graphs, scheduling theory and scheduling algorithms, and semidefinite programs.
First multi-year cumulation covers six years: 1965-70.
This textbook is designed for a one-year graduate course in real algebraic geometry, with a particular focus on positivity and sums of squares of polynomials. The first half of the book features a thorough introduction to ordered fields and real closed fields, including the Tarski-Seidenberg projection theorem and transfer principle. Classical results such as Artin's solution to Hilbert's 17th problem and Hilbert's theorems on sums of squares of polynomials are presented in detail. Other features include careful introductions to the real spectrum and to the geometry of semialgebraic sets. The second part studies Archimedean positivstellensätze in great detail and in various settings, togeth...
At a time when the Humanities are under threat, this book offers a defense of poetry within the context of growing interest in mindfulness in business, health care, and education. The book argues that the benefits and insights mindfulness provides are also cultivated by the study of poetry. These benefits include a focus on the present, the ability to see through scripts and habits, a rethinking of subjectivity, and the development of ecological or systems thinking. Bryan Walpert employs close readings of traditional and experimental poetry and draws on scientific studies of the effects of mindfulness or reading literature on the brain. It argues the skills that poetry, like mindfulness, cultivates are useful beyond the page or classroom and ultimately are necessary to engage with such global issues as the environmental crisis.
This study provides important empirical background to the continuing debate on Canadian industrial policy and trade. The analysis is based on primary data derived from a unique survey of individual firms, both Canadian and foreign-owned, conducted early in the 1981-1982 recession. The main purpose of the study is to assess whether recent changes in tariffs, exchange rates, wage rates, and other factors in Canada and the world economy suggest the need for any significant modification in the earlier analyses and conclusions. The study presents prior evidence on costs, specialization, and trade; assesses current costs and productivity, and presents new information on how increased exports and specialization would affect cost performance and international competitiveness; examines non-production costs and other non-cost influences on specialization and export performance; and suggests strategies for the private sector to consider in order to survive in the changing trade environment of the 1980s.
This book represents a crucial resource for students taking a required statistics course who are intimidated by statistical symbols, formulae, and daunting equations. It will serve to prepare the reader to achieve the level of statistical literacy required not only to understand basic statistics, but also to embark on their advanced-level statistics courses without anxiety. The application of statistics in social research has recently become imperative. However, a gap usually exists between the time when students take their first statistics course and when they engage in their first serious research project, meaning that they often don’t remember basic statistics well enough to apply it effectively in their research. In this sense, this book will also serve as an excellent “desk reference,” “refresher,” or “core concept” text for burgeoning researchers interning or working as a research assistant or research associate. Furthermore, the text is written in a self-help, hands-on learning style so the reader can easily attain the skills needed to achieve a basic understanding of statistics found in articles and presentations.
This volume provides a selection of previously published papers and manuscripts of Uno Kaljulaid, an eminent Estonian algebraist of the last century. The central part of the book is the English translation of Kaljulaid's 1979 Candidate thesis, which originally was typewritten in Russian and manufactured in not so many copies. The thesis is devoted to representation theory in the spirit of his thesis advisor B.I. Plotkin: representations of semigroups and algebras, especially extension to this situation, and application of the notion of triangular product of representations for groups introduced by Plotkin. Through representation theory, Kaljulaid became also interested in automata theory, wh...
