This book highlights some of the unique aspects of spatio-temporal graph data from the perspectives of modeling and developing scalable algorithms. The authors discuss in the first part of this book, the semantic aspects of spatio-temporal graph data in two application domains, viz., urban transportation and social networks. Then the authors present representational models and data structures, which can effectively capture these semantics, while ensuring support for computationally scalable algorithms. In the first part of the book, the authors describe algorithmic development issues in spatio-temporal graph data. These algorithms internally use the semantically rich data structures developed in the earlier part of this book. Finally, the authors introduce some upcoming spatio-temporal graph datasets, such as engine measurement data, and discuss some open research problems in the area. This book will be useful as a secondary text for advanced-level students entering into relevant fields of computer science, such as transportation and urban planning. It may also be useful for researchers and practitioners in the field of navigational algorithms.

MACSYMA for Statisticians introduces the basic principles and ideas of MACSYMA so that it can be used for mathematical computations, manipulations and simplifications. MACSYMA is a large computer programming system which is designed to perform a wide spectrum of mathematical computations and manipulations in symbolic as well as numerical form. It operates interactively and displays results in ordinary mathematical notation. MACSYMA is perhaps most well known for its capabilities in algebraic manipulations and simplifications. However, its usefulness extends much further than that. In the field of analysis, MACSYMA performs differentiation, integration and the taking of limits. It can compute definite integrals, change variables, perform integration by parts, reduce rational polynomials into partial fractions and take Laplace transforms. MACSYMA has several commands relating to Taylor Series and asymptotic expansions.

Ecological Assessment of Polymers Strategies for Product Stewardship and Regulatory Programs John D. Hamilton and Roger Sutcliffe The expense of providing ecological assessments of new commercial products is formidable. The cost of the failure to comply with the current regulations--measured in fines, liability damages, and loss of public trust--is potentially much, much higher. Establishing effective environmental product stewardship strategies for assessment upfront not only promotes initial and continued compliance, it can reduce costs via the more efficient development of new products. Based on the collaboration of the Rohm and Haas Company and S.C. Johnson Wax with other manufacturers, contract laboratories, universities, and government agencies, Ecological Assessment of Polymers is the first complete reference to provide environment-oriented information about polymers from a product development and regulatory compliance perspective. A number of books deal with the potential hazards of pesticides and solvents. This is the first to focus on the commercial synthetic polymers that exist in laundry detergents, paints, super-absorbent diapers, packaging materials, and many other consumer and industrial products. Using the principles of environmental toxicology and chemistry, Ecological Assessment of Polymers approaches environmental evaluation as a decision-making process. The book demonstrates how assessment can be used as a planning tool for developing products, reducing potential liability, and creating new products, processes, and disposal systems. Featured discussions:

• Overviews of methods, instrumentation, and databases used by environmental scientists to assessprocesses/products involving polymers
• Environmental regulatory assessment schemes for preventing dangerous environmental exposure during manufacture, use, transport, storage, and disposal
• Interpretations of ecotoxicity and fate tests with polymers
• New directions of research in degradable polymers
• Life-Cycle Assessment (LCA) of polymers
• Polymer regulations from the United States, Canada, Europe, and the Pacific Region

This book examines a writing activity that has recently fallen into disrepute. Outlining has a bad reputation among students, even though many teachers and textbooks still recommend the process. In part, the author argues, the medium is to blame. Paper and ink make the revision difficult. But if one uses an electronic outliner, the activity can be very helpful in developing a thoughtful and effective document, particularly one that spans many pages and deals with a complicated subject. Outlining Goes Electronic takes an historical approach, examining the way people developed the idea of outlining, from the classical period to the present. We see that the medium in which people worked strongly shaped their assumptions, ideas, and use of outlines. In developing a theoretical model of outlining as an activity, the author argues that a relatively new electronic tool-software that accelerates and performs the process of outlining-can give us a new perspective from which to engage previous classroom models of writing, recent writing theory, and current practice in the technical writing field.

This work presents the Clifford-Cauchy-Dirac (CCD) technique for solving problems involving the scattering of electromagnetic radiation from materials of all kinds. It allows anyone who is interested to master techniques that lead to simpler and more efficient solutions to problems of electromagnetic scattering than are currently in use. The technique is formulated in terms of the Cauchy kernel, single integrals, Clifford algebra and a whole-field approach. This is in contrast to many conventional techniques that are formulated in terms of Green's functions, double integrals, vector calculus and the combined field integral equation (CFIE). Whereas these conventional techniques lead to an implementation using the method of moments (MoM), the CCD technique is implemented as alternating projections onto convex sets in a Banach space. The ultimate outcome is an integral formulation that lends itself to a more direct and efficient solution than conventionally is the case, and applies without exception to all types of materials. On any particular machine, it results in either a faster solution for a given problem or the ability to solve problems of greater complexity. The Clifford-Cauchy-Dirac technique offers very real and significant advantages in uniformity, complexity, speed, storage, stability, consistency and accuracy.

This book addresses Software-Defined Radio (SDR) baseband processing from the computer architecture point of view, providing a detailed exploration of different computing platforms by classifying different approaches, highlighting the common features related to SDR requirements and by showing pros and cons of the proposed solutions. It covers architectures exploiting parallelism by extending single-processor environment (such as VLIW, SIMD, TTA approaches), multi-core platforms distributing the computation to either a homogeneous array or a set of specialized heterogeneous processors, and architectures exploiting fine-grained, coarse-grained, or hybrid reconfigurability.

This book will raise awareness and spark an international collaboration amongst global leaders to research the feasibility of a globally interoperable electronic health record system to prevent the international spread of disease, document patient treatment, travel, and transmission of BSL-4 infections. The problem of the spread of disease and the lack of multinational interoperability is a global problem and requires a global effort to establish interoperable systems protocols. This book focuses on the feasibility and design of a multinational or globally interoperable electronic health record system to track and prevent the spread of disease of BSL-4 infections. Due to the rapid spread of COVID-19 and the history of the multinational spread of zoonotic diseases, it is clear that a global effort is needed. The WHO stated that the lack of EHR interoperability and the spread of disease is a global problem that requires a global solution. This book is a critical exploration on this topic.

The philosophy of computer science is concerned with issues that arise from reflection upon the nature and practice of the discipline of computer science. This book presents an approach to the subject that is centered upon the notion of computational artefact. It provides an analysis of the things of computer science as technical artefacts. Seeing them in this way enables the application of the analytical tools and concepts from the philosophy of technology to the technical artefacts of computer science. With this conceptual framework the author examines some of the central philosophical concerns of computer science including the foundations of semantics, the logical role of specification, the nature of correctness, computational ontology and abstraction, formal methods, computational epistemology and explanation, the methodology of computer science, and the nature of computation. The book will be of value to philosophers and computer scientists.

This book systematically examines and quantifies industrial problems by assessing the complexity and safety of large systems. It includes chapters on system performance management, software reliability assessment, testing, quality management, analysis using soft computing techniques, management analytics, and business analytics, with a clear focus on exploring real-world business issues. Through contributions from researchers working in the area of performance, management, and business analytics, it explores the development of new methods and approaches to improve business by gaining knowledge from bulk data. With system performance analytics, companies are now able to drive performance and provide actionable insights for each level and for every role using key indicators, generate mobile-enabled scorecards, time series-based analysis using charts, and dashboards. In the current dynamic environment, a viable tool known as multi-criteria decision analysis (MCDA) is increasingly being adopted to deal with complex business decisions. MCDA is an important decision support tool for analyzing goals and providing optimal solutions and alternatives. It comprises several distinct techniques, which are implemented by specialized decision-making packages. This book addresses a number of important MCDA methods, such as DEMATEL, TOPSIS, AHP, MAUT, and Intuitionistic Fuzzy MCDM, which make it possible to derive maximum utility in the area of analytics. As such, it is a valuable resource for researchers and academicians, as well as practitioners and business experts.

The present work provides a platform for leading Data designers whose vision and creativity help us to anticipate major changes occurring in the Data Design field, and pre-empt the future. Each of them strives to provide new answers to the question, "What challenges await Data Design?" To avoid falling into too narrow a mind-set, each works hard to elucidate the breadth of Data Design today and to demonstrate its widespread application across a variety of business sectors. With end users in mind, designer-contributors bring to light the myriad of purposes for which the field was originally intended, forging the bond even further between Data Design and the aims and intentions of those who contribute to it. The first seven parts of the book outline the scope of Data Design, and presents a line-up of "viewpoints" that highlight this discipline's main topics, and offers an in-depth look into practices boasting both foresight and imagination. The eighth and final part features a series of interviews with Data designers and artists whose methods embody originality and marked singularity. As a result, a number of enlightening concepts and bright ideas unfold within the confines of this book to help dispel the thick fog around this new and still relatively unknown discipline. A plethora of equally eye-opening and edifying new terms, words, and key expressions also unfurl. Informing, influencing, and inspiring are just a few of the buzz words belonging to an initiative that is, first and foremost, a creative one, not to mention the possibility to discern the ever-changing and naturally complex nature of today's datasphere. Providing an invaluable and cutting-edge resource for design researchers, this work is also intended for students, professionals and practitioners involved in Data Design, Interaction Design, Digital & Media Design, Data & Information Visualization, Computer Science and Engineering.
