This book is concerned with the importance of Human Computer Interaction (HCI), Usability, user participants, and Sustainability in the Information Communication Technology (ICT) industry throughout the world. ICT has become a crucial instrument for communication, entertainment, commerce and research and this increased usage is presenting new environmental and sustainability issues as we try and meet the ever growing needs of both businesses and individuals. Sustainability must become central to the design of new technologies to make a concerted effort to tackle the environmental concerns we face now and for the future. Development frameworks, tools and models are used and explored and the New Participative Methodology for Sustainable Design (NPMSD) is introduced as a way of identifying key factors needed in developing more sustainable systems including new smart technology and portable devices. It is hoped additional research will be carried out in the future to assess these sustainable design steps using larger, more diverse countries with developed and developing economies to further refine such methods. Sustainable Design will be an invaluable resource for students and researchers, designers and business managers who are interested in the human-centred, environmental concerns of sustainable technologies

Presenting an integrated and holistic perspective on innovation management and product design and development, this monograph offers a unique and original understanding of how these two perspectives are interconnected. This book explores these themes in a scientifically rigorous manner, associating academic findings with examples from business. It provides readers with the conceptual and decision-making tools required to understand and manage the process of innovation at different levels, from the analysis of industry-wide phenomena to the formulation of a strategy and from the planning of operations to the management of technical choices. Chapters cover innovation as an economic and social phenomenon, the formulation of innovation strategy, the management of product development processes and projects and the technical design of products and services. Offering an invaluable resource to postgraduate students in economics, business and engineering, this book is also intended for managers and entrepreneurs.

Sir William Rowan Hamilton was a genius, and will be remembered for his significant contributions to physics and mathematics. The Hamiltonian, which is used in quantum physics to describe the total energy of a system, would have been a major achievement for anyone, but Hamilton also invented quaternions, which paved the way for modern vector analysis. Quaternions are one of the most documented inventions in the history of mathematics, and this book is about their invention, and how they are used to rotate vectors about an arbitrary axis. Apart from introducing the reader to the features of quaternions and their associated algebra, the book provides valuable historical facts that bring the subject alive. Quaternions for Computer Graphics introduces the reader to quaternion algebra by describing concepts of sets, groups, fields and rings. It also includes chapters on imaginary quantities, complex numbers and the complex plane, which are essential to understanding quaternions. The book contains many illustrations and worked examples, which make it essential reading for students, academics, researchers and professional practitioners.

In my last book, Geometry for Computer Graphics, I employed a mixture of algebra and vector analysis to prove many of the equations used in computer graphics. At the time, I did not make any distinction between the two methodologies, but slowly it dawned upon me that I had had to discover, for the first time, how to use vector analysis and associated strategies for solving geometric problems. I suppose that mathematicians are taught this as part of their formal mathematical training, but then, I am not a mathematician! After some deliberation, I decided to write a book that would introduce the beginner to the world of vectors and their application to the geometric problems encountered in computer graphics. I accepted the fact that there would be some duplication of formulas between this and my last book; however, this time I would concentrate on explaining how problems are solved. The book contains eleven chapters: The first chapter distinguishes between scalar and vector quantities, which is reasonably straightforward. The second chapter introduces vector repres- tation, starting with Cartesian coordinates and concluding with the role of direction cosines in changes in axial systems. The third chapter explores how the line equation has a natural vector interpretation and how vector analysis is used to resolve a variety of line-related, geometric problems. Chapter 4 repeats Chapter 3 in the context of the plane.

This book comprehensively covers a range of pathological cases in clinical cardiology. Chapters are case focused and detail how a patient is diagnosed and treated in a step-by-step format. A range of engaging video clips enhances the reader¿s appreciation and understanding of how to apply these techniques into their day-to-day clinical practice with special focus on congenital heart disease diagnosis and management.Case-Based Clinical Cardiology presents a range of clinical scenarios across all cardiology disciplines with a particular focus on echocardiography, electrocardiography and cardiac catheterization. Therefore, it is an ideal resource for both the novice and experienced cardiology practitioner seeking an up-to-date selection of cases to test their knowledge.

In Vivo Confocal Microscopy in Eye Disease is a comprehensive new text that covers the latest advances in the field of in vivo confocal imaging. It presents a detailed overview of the basic anatomy of the different part of the cornea, conjunctiva and adnexal structures. It discusses the use of in vivo confocal microscopy in a range of clinical applications including the diagnosis of infective keratitis, corneal dystrophies, cornea nerves, conjunctival diseases and their differentiating features. Numerous confocal images, clinical pictures, other paraclinical images and histopathology slides of different ocular pathologies are examined and presented throughout the text.This book systematically reviews the use of confocal imaging in basic science of ocular tissues to the diagnosis of eye disease assembled in a single volume. It provides an up to date resource with an in depth review of scientific literature relating to both the clinical and research application of in vivo confocal microscopy in eye disease. The book ends with a discussion on non-ocular application of in vivo confocal microscopy and future developments including other emerging imaging technologies. This text will provide an invaluable resource for those who are interested in ocular imaging and it represents a timely resource for all practicing and trainee ophthalmologists
