Description

This book addresses selected topics in the theory of generalized inverses. Following a discussion of the “reverse order law” problem and certain problems involving completions of operator matrices, it subsequently presents a specific approach to solving the problem of the reverse order law for {1} -generalized inverses.

Particular emphasis is placed on the existence of Drazin invertible completions of an upper triangular operator matrix; on the invertibility and different types of generalized invertibility of a linear combination of operators on Hilbert spaces and Banach algebra elements; on the problem of finding representations of the Drazin inverse of a 2x2 block matrix; and on selected additive results and algebraic properties for the Drazin inverse.

In addition to the clarity of its content, the book discusses the relevant open problems for each topic discussed. Comments on the latest references on generalized inverses are also included. Accordingly, the book will be useful for graduate students, PhD students and researchers, but also for a broader readership interested in these topics.

Reviews:
“The diverse set of chapters in this unique volume speaks to the question of whether social psychological theories and principles are universal. The authors take the reader on a fascinating tour, highlighting some of the many domains and places in which social psychology has been applied. Some answers are provided, but equally richly many questions are raised. The approaches taken, notably the comparative approach adopted in several of the chapters, will challenge social psychologists to think about both how they conceptualize social problems and how they do and should research them.”
Miles Hewstone, Professor of Social Psychology, University of Oxford

The work contains seventeen articles reflecting scholarship in traditional and emerging areas of social psychology. Major topics addressed include the subjective evaluation of emotions; the psychology of values; self-definition; priming and racial stereotyping; selfrepresentation; self-harming; negative communications; visual communication and emotion recognition; comparative studies of values; duration of romantic relationships; interpersonal attraction; social psychological antecedents of burnout; social integration and language effects on bilinguals.

“This volume offers a truly panoramic picture of how scientific social psychology can address timely social issues. The editors recruited outstanding scientists spanning eleven nations to produce a collection that is as impressive in its remarkable diversity of nations as well as topics and methods. An ideal reader for a course in methods or social psychology.”
Harold Takooshian, Past President, APA division of International Psychology.

The essence of the conceptual design is getting the innovative projects or ideas to promise the products with best performance. It has been proved that the theory of inventive problem solution (TRIZ) is a systematic methodology for innovation. Passively compliant robotic joint design as an engineering example is presented in this book to show the significance and approaches of applying TRIZ into getting the creative conceptual design ideas. The main goal is to design the compliant robotic joint with conductive silicone rubber elements as internal sensors. The sensor elements can operate as absorbers of excessive external collision force instead of springs and dampers. Therefore, this joint presents one type of safe robotic mechanisms with an internally measuring system. The sensor elements were made by press-curing from carbon-black filled silicone rubber. The experimental results show that the greatest advantage of this material lies in its high stretchiness and high compression velocity. A new method is presented for detecting the direction of the robotic joint rotation when subjected to an external collision force.

Graph theory, as modern and young branches of mathematics, studies graphs which are abstract mathematical objects. The use of graph models for description or data structures is very common. Investigation of algorithms to solve problems using graph, is a very important part of computer science. The genetic algorithms represent a family of algorithms using some of genetic principles being present in nature, in order to solve particular computational problems.

These natural principles are: inheritance, crossover, mutation, survival of the fittest, migrations and so on. The problems degree-limited graph of nodes considering the weight of the vertex or weight of the edges, with the aim to find the optimal weighted graph in terms of certain restrictions on the degree of the vertices in the subgraph. This class of combinatorial problems was extensively studied because of the implementation and application in network design, connection of networks and routing algorithms. It is likely that solution of MDBCS problem will find its place and application in these areas.

ISBN-10: 1-60845-942-X

ISBN-13: 978-1-60845-942-1

Compared to binary switching functions, the multiple-valued functions (MV) offer more compact representations of the information content of signals modeled by logic functions and, therefore, their use fits very well in the general settings of data compression attempts and approaches.
 
This book presents in a uniform way different representations of multiple-valued logic functions, including functional expressions, spectral representations on finite Abelian groups, and their graphical counterparts (various related decision diagrams). Three-valued, or ternary functions, are traditionally used as the first extension from the binary case. They have a good feature that the ratio between the number of bits and the number of different values that can be encoded with the specified number of bits is favourable for ternary functions. Four-valued functions, also called quaternary functions, are particularly attractive, since in practical realization within today prevalent binary circuits environment, they may be easy coded by binary values and realized with two-stable state circuits. At the same time, there is much more considerable advent in design of four-valued logic circuits than for other p-valued functions.

Logic networks and automata are facets of digital systems. The change of the design of logic networks from skills and art into a scientific discipline was possible by the development of the underlying mathematical theory called the Switching Theory. The fundamentals of this theory come from the attempts towards an algebraic description of laws of thoughts presented in the works by George J. Boole and the works on logic by Augustus De Morgan.   As often the case in engineering, when the importance of a problem and the need for solving it reach certain limits, the solutions are searched by many scholars in different parts of the word, simultaneously or at about the same time, however, quite independently and often unaware of  the work by other scholars. The formulation and rise of Switching Theory is such an example.   This book presents a brief account of the developments of Switching Theory and highlights some less known facts in the history of it.  The readers will find the book a fresh look into the development of the field revealing how difficult it has been to arrive at many of the concepts that we now consider obvious. Researchers in the history or philosophy of computing will find this book a valuable source of information that complements the standard presentations of the topic.

There is heightened interest in spectral techniques for the design of digital devices dictated by ever increasing demands on technology that often cannot be met by classical approaches. Spectral methods provide a uniform and consistent theoretic environment for recent achievements in this area, which appear divergent in many other approaches. Spectral Logic and Its Applications for the Design of Digital Devices gives readers a foundation for further exploration of abstract harmonic analysis over finite groups in the analysis, design, and testing of digital devices. After an introduction, this book provides the essential mathematical background for discussing spectral methods.

This is the authoritative reference for computer science and engineering professionals and researchers with an interest in spectral methods of representing discrete functions and related applications in the design and testing of digital devices.
