Written to teach students the nature of transonic flow and its mathematical foundation, this book offers a much-needed introduction to transonic aerodynamics. The authors present a quantitative and qualitative assessment of subsonic, supersonic and transonic flow around bodies in two and three dimensions. The book reviews the governing equations and explores their applications and limitations as employed in modeling and computational fluid dynamics. Some concepts, such as shock and expansion theory, are examined from a numerical perspective. Others, including shock-boundary-layer interaction, are discussed from a qualitative point of view. The book includes 60 examples and more than 200 practice problems. The authors also offer analytical methods such as Method of Characteristics (MOC) that allow readers to practice with the subject matter. The result is a wealth of insight into transonic flow phenomena and their impact on aircraft design, including compressibility effects, shock and expansion waves, shock-boundary-layer interaction and aeroelasticity.

As understanding of the engineering design and configuration processes grows, the recognition that these processes intrinsically involve imprecise information is also growing. This book collects some of the most recent work in the area of representation and manipulation of imprecise information during the syn thesis of new designs and selection of configurations. These authors all utilize the mathematics of fuzzy sets to represent information that has not-yet been reduced to precise descriptions, and in most cases also use the mathematics of probability to represent more traditional stochastic uncertainties such as un controlled manufacturing variations, etc. These advances form the nucleus of new formal methods to solve design, configuration, and concurrent engineering problems.

This requires their full compatibility, both in terms of ensuring optimum safety and comfort of use. The authors have chosen the material according to the needs of people directly responsible for safety at work and users of those protectors. The main aim of the work is to popularise knowledge in the field of construction, research methods, selection and use of protective helmets and eye and face protectors. In terms of use, the authors emphasise the necessity of independent control, i.e. checking the technical condition of the equipment used by the end users. The presented monograph includes the current state of knowledge in this scope, extended by the results and summaries of the authors' own research. All requirements and research methods are given based on European (EN), international (ISO) standards and standards operating in different geographical areas. The monograph also encompasses new trends in the design of protective helmets and eye and face protectors. All this allows me to emphasize the uniqueness of this monograph in relation to previous publications in this field, both in terms of the scope and selection of information concerning protective helmets and eye and face protectors." - Ryszard Korycki, Lodz University of Technology

The volume should be especially useful for researchers and practitioners in the fields of HRM and information technology.

Post Normal Accident revisits Perrow's classic Normal Accident published in 1984 and provides additional insights to our sociological view of safety-critical organisations. The operating landscape of high-risk systems has indeed profoundly changed in the past 20 to 30 years but the core sociological models of safety remain associated with classics of the 1980s and 1990s. This book examines the conceptual and empirical evolutions of the past two to three decades to explore their implications for safety management, based on several strands of works in various research traditions in safety (e.g. cognitive engineering and system safety, high-reliability organisation, sociology of safety, regulatory studies) and other interdisciplinary fields (e.g. international business, globalisation studies, strategy management, ecology). It offers a new and inciteful interpretation to the challenges of today. It investigates how globalisation has reconfigured the operating landscape of high-risk systems and emphasises the importance of thinking safety through a strategic angle. This book serves as an ideal resource for the safety professionals and safety researchers from any established disciplines such as sociology, engineering, psychology, political science or management.

This new handbook is about the practices of conducting research on military issues. As an edited collection, it brings together an extensive group of authors from a range of disciplinary perspectives whose chapters engage with the conceptual, practical and political questions raised when doing military research. The book considers a wide range of questions around research about, on and with military organisations, personnel and activities, from diverse starting-points across the social sciences, arts and humanities. Each chapter in this volume: Describes the nature of the military research topic under scrutiny and explains what research practices were undertaken and why. Discusses the author's research activities, addressing the nature of their engagement with their subjects and explaining how the method or approach under scrutiny was distinctive because of the military context or subject of the research. Reflects on the author's research experiences, and the specific, often unique, negotiations with the politics and practices of military institutions and military personnel before, during and after their research fieldwork. The book provides a focussed overview of methodological approaches to critical studies of military personnel and institutions, and processes and practices of militarisation and militarism. In particular, it engages with the growth in qualitative approaches to military research, particularly research carried out on military topics outside military research institutions. The handbook provides the reader with a comprehensive guide to how critical military research is being undertaken by social scientists and humanities scholars today, and sets out suggestions for future approaches to military research. This book will be of much interest to students of military studies, war and conflict studies, and research methods in general.

Design is about the creation of meaningful connections to solve problems and advance human wellbeing; the discipline has always explored the beneficial links between form and function, technology and meaning, beauty and utility, people and artefacts and problems and solutions, among others. This book focuses on the crucial connection between design research and design education. Contemporary society grows increasingly hyper-complex and globally competitive. This state of affairs raises fundamental questions for both Design Education and Design Research: Should research skills be integrated into undergraduate courses? How can we modify design courses without compromising the positive aspects of the educational studio experience? Can the three cycles of higher education in design be combined into a creative and inquisitive educational continuum? To examine the relationship between research and education in Design we must address the topic of knowledge, keeping in mind that the development and dissemination of new and useful knowledge is the core purpose of a University. If we agree that design has its own things to know and ways to find out about them, then design knowledge resides in people, processes, products, and philosophy. This book explores the intersection of these four areas with the aim of uncovering insights to advance the current state of the design discipline.

Given the growing size and heterogeneity of Systems on Chip (SOC), the design process from initial specification to chip fabrication has become increasingly complex. This growing complexity provides incentive for designers to use high-level languages such as C, SystemC, and SystemVerilog for system-level design. While a major goal of these high-level languages is to enable verification at a higher level of abstraction, allowing early exploration of system-level designs, the focus so far for validation purposes has been on traditional testing techniques such as random testing and scenario-based testing. This book focuses on high-level verification, presenting a design methodology that relies upon advances in synthesis techniques as well as on incremental refinement of the design process. These refinements can be done manually or through elaboration tools. This book discusses verification of specific properties in designs written using high-level languages, as well as checking that the refined implementations are equivalent to their high-level specifications. The novelty of each of these techniques is that they use a combination of formal techniques to do scalable verification of system designs completely automatically. The verification techniques presented in this book include methods for verifying properties of high-level designs and methods for verifying that the translation from high-level design to a low-level Register Transfer Language (RTL) design preserves semantics. Used together, these techniques guarantee that properties verified in the high-level design are preserved through the translation to low-level RTL.

Gait analysis is the systematic study of human walking, using the eye and brain of experienced observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. Since Aristotle's work on gait analysis more than 2000 years ago, it has become an established clinical science used extensively in the healthcare and rehabilitation fields for diagnosis and treatment. Forensic Gait Analysis details the more recent, and rapidly developing, use of gait analysis in the forensic sciences. The book considers the use of observational gait analysis, based on video recordings, to assist in the process of identification or exclusion. With the increase in use of CCTV and surveillance systems over the last 20 to 30 years, there has been a steady and rapid increase in the use of gait as evidence. Currently, gait analysis is widely used in the UK in criminal investigations, with increasing awareness of its potential use in the US, Europe, and globally. The book details the history of the science, current practices, and of the emergent application to establish best-practice standards that conform to those of other forensic science disciplines. Engagement with the Forensic Science Regulator, and the Chartered Society of Forensic Sciences in the UK, and the International Association for Identification has helped to ensure and enhance the quality assurance of forensic gait analysis. However, there remains a fundamental lack of standardized training and methodology for use in evidentiary and investigative casework. This book fills that void, serving as one of the first to describe the current state of practice, capabilities and limitations, and to outline methods, standards of practice and expectations of the gait analyst as a forensic practitioner. Forensic Gait Analysis reflects current research and forensic practice and will serve as a state-of-the-art guide to the use of gait analysis in the forensic context-for both education and training purposes. It will be a welcome addition to the libraries of professionals in the areas of podiatry, gait analysis, forensic video analysis, law enforcement, and legal practice.

Among all aspects of engineering, design is the most important step in developing a new product. A systematic approach to managing design issues can only be accomplished by applying mathematical optimization methods. Furthermore, due to the practical issues in engineering problems, there are limitations in using traditional methods. As such, stochastic optimization methods such as differential evolution, simulated annealing, and genetic algorithms are preferable in finding solutions in design optimization problems. This book reviews mechanical engineering design optimization using stochastic methods. It introduces students and design engineers to practical aspects of complicated mathematical optimization procedures, and outlines steps for wide range of selected engineering design problems. It shows how engineering structures are systematically designed. Many new engineering design applications based on stochastic optimization techniques in automotive, energy, military, naval, manufacturing process and fluids-heat transfer, are described in the book. For each design optimization problem described, background is provided for understanding the solutions. There are very few books on optimization that include engineering applications. They cover limited applications, and that too of well-known design problems of advanced and niche nature. Common problems are hardly addressed. Thus, the subject has remained fairly theoretical. To overcome this, each chapter in this book is contributed by at least one academic and one industrial expert researcher.

This book explores systems-based, co-design, introducing a "Decision-Based, Co-Design" (DBCD) approach for the co-design of materials, products, and processes. In recent years there have been significant advances in modeling and simulation of material behavior, from the smallest atomic scale to the macro scale. However, the uncertainties associated with these approaches and models across different scales need to be addressed to enable decision-making resulting in designs that are robust, that is, relatively insensitive to uncertainties. An approach that facilitates co-design is needed across material, product design and manufacturing processes. This book describes a cloud-based platform to support decisions in the design of engineered systems (CB-PDSIDES), which feature an architecture that promotes co-design through the servitization of decision-making, knowledge capture and use templates that allow previous solutions to be reused. Placing the platform in the cloud aids mass collaboration and open innovation. A valuable reference resource reference on all areas related to the design of materials, products and processes, the book appeals to material scientists, design engineers and all those involved in the emerging interdisciplinary field of integrated computational materials engineering (ICME).

Physical and behavioral biometric technologies such as fingerprinting, facial recognition, voice identification, etc. have enhanced the level of security substantially in recent years. Governments and corporates have employed these technologies to achieve better customer satisfaction. However, biometrics faces major challenges in reducing criminal, terrorist activities and electronic frauds, especially in choosing appropriate decision-making algorithms. To face this challenge, new developments have been made, that amalgamate biometrics with artificial intelligence (AI) in decision-making modeling. Advanced software algorithms of AI, processing information offered by biometric technology, achieve better results. This has led to growth in the biometrics technology industry, and is set to increase the security and internal control operations manifold. This book provides an overview of the existing biometric technologies, decision-making algorithms and the growth opportunity in biometrics. The book proposes a throughput model, which draws on computer science, economics and psychology to model perceptual, informational sources, judgmental processes and decision choice algorithms. It reviews how biometrics might be applied to reduce risks to individuals and organizations, especially when dealing with digital-based media.

In order to compete in the current commercial environment companies must produce greater product variety, at lower cost, all within a reduced product life cycle. To achieve this, a concurrent engineering philosophy is often adopted. In many cases the main realization of this is Design for Manufacture and Assembly (DFM/A). There is a need for in-depth study of the architectures for DFM/A systems in order that the latest software and knowledge-based techniques may be used to deliver the DFM/A systems of tomorrow. This architecture must be based upon complete understanding of the issues involved in integrating the design and manufacturing domains. This book provides a comprehensive view of the capabilities of advanced DFM/A systems based on a common architecture.
