Universal Design Principles for Architecting Modular Software Systems

Virtual machines have been critical software systems for decades and now platforms such as Apple iOS, Google Android, and Microsoft Windows Phone all need them as primary application execution engines

Structured methodologies are a popular and powerful tool in information systems development. Many different ones exist, each employing a number of models and so a specification must be converted from one form to another during the development process. To solve this problem, Dr Tse proposes in this 1991 book a unifying framework behind popular structured models. He approaches the problem from the viewpoints of algebra and category theory. He not only develops the frameworks but also illustrates their practical and theoretical usefulness. Thus this book will provide insight for software engineers into how methodologies can be formalised and will open up a range of applications and problems for theoretical computer scientists.

The Art and Science of Optical Design is a comprehensive introduction to lens design, covering the fundamental physical principles and key engineering issues. Several practical examples of modern computer-aided lens design are worked out in detail from start to finish. The basic theory and results of optics are presented early on in the book, along with a discussion of optical materials. Aberrations, and their correction, and image analysis are then covered in great detail. Subsequent chapters deal with design optimisation and tolerance analysis. Several design examples are then given, beginning with basic lens design forms, and progressing to advanced systems, such as gradient index and diffractive optical components. In covering all aspects of optical design, including the use of modern lens design software, this book will be invaluable to students of optical engineering as well as to anyone engaged in optical design at any stage.

Around the world, children embark on learning to read in their home language or writing system. But does their specific language, and how it is written, make a difference to how they learn? How is learning to read English similar to or different from learning in other languages? Is reading alphabetic writing a different challenge from reading syllabic or logographic writing? Learning to Read across Languages and Writing Systems examines these questions across seventeen languages representing the world's different major writing systems. Each chapter highlights the key features of a specific language, exploring research on learning to read, spell, and comprehend it, and on implications for education. The editors' introduction describes the global spread of reading and provides a theoretical framework, including operating principles for learning to read. The editors' final chapter draws conclusions about cross-linguistic universal trends, and the challenges posed by specific languages and

Risk has always been central to finance, and managing risk depends critically on information. As evidenced by recent events, the need has never been greater for skills, systems and methodologies to manage risk information in financial markets. Authored by leading figures in risk management and analysis, this handbook serves as a unique and comprehensive reference for the technical, operational, regulatory and political issues in collecting, measuring and managing financial data. It will appeal to a wide range of audiences, from financial industry practitioners and regulators responsible for implementing risk management systems, to system integrators and software firms helping to improve such systems. Volume I examines the business and regulatory context that makes risk information so important. A vast set of techniques and processes have grown up over time, and without an understanding of the broader forces at work, it is all too easy to get lost in the details.

The digital economy led to many new services where supply is matched with demand for various types of goods and services. More and more people and organizations are now in a position to design market rules that are being implemented in software. The design of markets is challenging as it needs to consider strategic behavior of market participants, psychological factors, and computational problems in order to implement the objectives of a designer. Market models in economics have not lost their importance, but the recent years have led to many new insights and principles for the design of markets, which are beyond traditional economic theory. This book introduces the fundamentals of market design, an engineering field concerned with the design of real-world markets.

Nearly all major global financial centres have developed systems of consumer financial dispute resolution. Such systems aim to assist parties to resolve a growing number of monetary disputes with financial institutions. How governments and self-regulatory organizations design and administer financial dispute resolution mechanisms in the context of increasingly turbulent financial markets is a new area for research and practice. Consumer Financial Dispute Resolution in a Comparative Context presents comparative research about the development and design of these mechanisms in East Asia, North America and Europe. Using a comparative methodology and drawing on empirical findings from a multi-jurisdictional survey, Shahla F. Ali examines the emergence of global principles that influence the design of financial dispute resolution models, considers the structural variations between the ombuds and arbitration systems, and offers practical proposals for reform.

The Business of Projects broke ground when it was first published in 2005, by showing how leading businesses create and implement projects to drive strategy and innovation. Projects are used to coordinate activities with customers and suppliers and ensure that organisations become more dynamic and adaptable. The book extends the resource-based view of the firm to focus on the business lessons learned from the design and production of high-value complex products and systems (CoPS), which have always been project-based. As well as frameworks and management tools, it provides case studies of high-technology industries - such as telecommunications, flight simulation and medical devices - to show how projects are used to achieve strategic objectives, perform systems integration, organise productive activities, manage software, achieve organisational learning and deliver solutions for customers. This book is essential reading for project professionals, academics, students, engineers, manager

This book provides, for the first time, a broad and deep treatment of the fields of both ultra low power electronics and bioelectronics. It discusses fundamental principles and circuits for ultra low power electronic design and their applications in biomedical systems. It also discusses how ultra energy efficient cellular and neural systems in biology can inspire revolutionary low power architectures in mixed-signal and RF electronics.
