Matrix positivity is a central topic in matrix theory: properties that generalize the notion of positivity to matrices arose from a large variety of applications, and many have also taken on notable theoretical significance, either because they are natural or unifying. This is the first book to provide a comprehensive and up-to-date reference of important material on matrix positivity classes, their properties, and their relations. The matrix classes emphasized in this book include the classes of semipositive matrices, P-matrices, inverse M-matrices, and copositive matrices. This self-contained reference will be useful to a large variety of mathematicians, engineers, and social scientists, as well as graduate students. The generalizations of positivity and the connections observed provide a unique perspective, along with theoretical insight into applications and future challenges. Direct applications can be found in data analysis, differential equations, mathematical programming, compu

Finite-state methods are the most efficient mechanisms for analysing textual and symbolic data, providing elegant solutions for an immense number of practical problems in computational linguistics and computer science. This book for graduate students and researchers gives a complete coverage of the field, starting from a conceptual introduction and building to advanced topics and applications. The central finite-state technologies are introduced with mathematical rigour, ranging from simple finite-state automata to transducers and bimachines as 'input-output' devices. Special attention is given to the rich possibilities of simplifying, transforming and combining finite-state devices. All algorithms presented are accompanied by full correctness proofs and executable source code in a new programming language, C(M), which focuses on transparency of steps and simplicity of code. Thus, by enabling readers to obtain a deep formal understanding of the subject and to put finite-state methods t

Engineers face numerous uncertainties in the design and development of products and processes. To deal with the uncertainties inherent in measured information, they make use of a variety of statistical techniques. This 1999 book presents single-variable statistical distributions that are useful in engineering design and analysis. It lists significant properties of these distributions and describes methods for estimating parameters and their standard errors, constructing confidence intervals, testing hypotheses, and plotting data. Figures are used extensively to clarify concepts. Methods are illustrated by numerous fully worked examples in the form of Mathcad documents that readers can use as templates for their own data, eliminating the need for programming. Intended as both a text and reference, the book assumes an elementary knowledge of calculus and probability. Graduate and advanced undergraduate students, as well as practising engineers and scientists, will be able to use this bo

The primary object of this manual is to build an understanding of the principles of computer operations and the use of computers in the laboratory. While the development of applications for computers has been rapid since their introduction, the principles of computer operation and their use in sensing and control have remained stable. Those are the primary subjects of this book, throughout which a gradual understanding of what goes on inside a computer is developed. The laboratory provides a vital experience in linking theory with physical reality, and all of the computer work is done in the context of doing experiments. The IBM-PC design is used as the basis for the book. The internal design of this machine is slightly more complicated than earlier personal computers, but it is still simple enough to be quickly learned. The computer can be directly controlled by proper programming, and offers considerably more power than earlier designs. The IBM design also has expansion slots which m

An unruly cast of emotions come alive in this romping dreamworld, a place Maurice Sendak's Wild Things could call home Curiosity, a lithe and floppy-eared creature, perches above the open world and gazes out with a zippy blend of hope, wonder, and longing. From the tip of a chimney, we bound into the quiet and mischievous world of feelings, meeting a troupe of tufted creatures as we go. Sympathy helps snails cross a sidewalk to safety, fear pirouettes in an attempt to camouflage with wallflowers, and pleasure reclines across a doily-donned reading chair, sipping a cup of tea. Elsewhere, our insecurities - pesky, cavorting beings - build intricate cages and stride about with clattering sets of keys. Tina Oziewicz's words hum with truth, and Aleksandra Zajac's illustrations bloom and burst with charming details like a sail constructed out of a pair of billowing long johns or a red slipper falling from a contented paw. Taking in the perfect harmony of this book is like taking a long gulp

Jinwoo is alarmed to learn about the timeless war between the Monarchs and the Rulers―a war that, according to the King of the Giants, will soon rage on Earth.

The two members of Ahjin Guild head for the US to attend the International Guild Conference and get to the bottom of things. Little do they realize that setting foot in America means crossing paths with Dongsoo Hwang, who has a bone to pick with Jinwoo about the death of his brother―and isn’t above using Jinho as bait!

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.Among the many things expectant parents are told to buy, none is a more visible symbol of status and parenting philosophy than a stroller. Although its association with wealth dates back to the invention of the first pram in the 1700s, in recent decades, four-figure strollers have become not just status symbols but cultural identifiers. There are sleek jogging strollers for serious athletes, impossibly compact strollers for parents determined to travel internationally with pre-ambulatory children, and those featuring a ride-on kick board or second, less “babyish” seat, designed with older siblings in mind. Despite the many models available, we are all familiar with the image of a harried mother struggling to use a stroller of any kind in a public space that does not accommodate it. There are anti-stroller evangelists, fervently preaching the gospel of baby wearing and attachment pa

A guide to computational thinking education, with a focus on artificial intelligence literacy and the integration of computing and physical objects. Computing has become an essential part of today’s primary and secondary school curricula. In recent years, K–12 computer education has shifted from computer science itself to the broader perspective of computational thinking (CT), which is less about technology than a way of thinking and solving problems―“a fundamental skill for everyone, not just computer scientists,” in the words of Jeanette Wing, author of a foundational article on CT. This volume introduces a variety of approaches to CT in K–12 education, offering a wide range of international perspectives that focus on artificial intelligence (AI) literacy and the integration of computing and physical objects. The book first offers an overview of CT and its importance in K–12 education, covering such topics as the rationale for teaching CT; programming as a general problem-solving

This Element critically surveys the full range of G. E. Moore's ethical thought, including: (1) his rejection of naturalism in favor of the view that 'good' designates a simple, indefinable property, which cannot be identified with or reduced to any other property; (2) his understanding of intrinsic value, his doctrine of organic wholes, his repudiation of hedonism, and his substantive account of the most important goods and evils; and (3) his critique of egoism and subjectivism and his elaboration of a non-hedonistic variant of utilitarianism that, among other things, creatively blends aspects of act- and rule-oriented versions of that theory.

The hosts of the podcast Stuff They Don’t Want You to Know, Ben Bowlin, Matthew Frederick, and Noel Brown discern conspiracy fact from conspiracy fiction in this exposé on stuff the government doesn’t want you to know.Conspiracies didn’t always seem so clear and present. It used to be that people with tin-foil hats who were convinced of secret messages coming through the radio were easily disregarded as kooks and looney tunes. But these days, conspiracies feel alive and well. From internet rumors to lying politicians to the tinderbox that is social media, it’s become remarkably clear that a vast swath of people believe really bonkers things.Why is that? How did these theories proliferate? Is there a kernel of truth to it or are they fully fiction? Ben Bowlin, Matt Frederick, and Noel Brown are the hosts of the popular iHeart podcast that seeks to answer these questions. With cool heads and extensive research, they regularly break down the wildest conspiracy theories: from chemtrails an

This innovative book models pollution mitigation as a negative externality whilst also providing desirable and useful solutions, such as establishing the triangular equivalence relationship among the Lindahl equilibrium without transfers, the Nash bargaining solution with the payoffs of the Cournot-Nash equilibrium as the status quo point, and the social optimum under the Lindahl weights. By introducing programming algorithms to validate these relationships numerically, Zili Yang bridges the gap between analytical results and empirical modelling, ultimately solving the Lindahl equilibrium and hybrid Nash equilibria in the influential RICE model. This text demonstrates the complexity and variety of environment externality problems, ranging from mixed externality to correlated externalities to environmental externality under IRS and policy applications. Integrating theory, algorithms and applications in a comprehensive framework, The Environment and Externality will benefit scholars and

Organizations and businesses strive toward excellence, and solutions to problems are based mostly on judgment and experience. However, increased competition and consumer demands require that the solutions be optimum and not just feasible. Theory leads to algorithms. Algorithms need to be translated into computer codes. Engineering problems need to be modeled. Optimum solutions are obtained using theory and computers, and then interpreted. Revised and expanded in its third edition, this textbook integrates theory, modeling, development of numerical methods, and problem solving, thus preparing students to apply optimization to real-world problems. This text covers a broad variety of optimization problems using: unconstrained, constrained, gradient, and non-gradient techniques; duality concepts; multi-objective optimization; linear, integer, geometric, and dynamic programming with applications; and finite element-based optimization. It is ideal for advanced undergraduate or graduate cours

There is widespread disagreement over what constitutes an experience of empathy. In this study of its value and moral features, Mark Fagiano acknowledges the ambiguity surrounding the term and offers a unified theory of empathy that includes rival definitions.His historical account of the multiple meanings of empathy lays the groundwork for a new philosophical theory. Based on relations, it resolves the problem of conflicting definitions of empathy by distinguishing between the three kinds of empathy: the relations of feeling into, feeling with, and feeling for, each of which has been defined historically as a type of empathy. Fagiano's unique focus on relations, on the modes and manner by which we are connected with things and with people, reveals a transactional account of empathy that can be applied to a variety of different contexts and social circumstances. Grounded in the philosophical tradition of American Pragmatism, Fagiano’s approach demonstrates the practical benefits of ad
