Rethinking the Internet of Things: A Scalable Approach to Connecting Everything
by Francis daCosta Byron HendersonApress is proud to announce that Rethinking the Internet of Things was a 2014 Jolt Award Finalist, the highest honor for a programming book. And the amazing part is that there is no code in the book.Over the next decade, most devices connected to the Internet will not be used by people in the familiar way that personal computers, tablets and smart phones are. Billions of interconnected devices will be monitoring the environment, transportation systems, factories, farms, forests, utilities, soil and weather conditions, oceans and resources.Many of these sensors and actuators will be networked into autonomous sets, with much of the information being exchanged machine-to-machine directly and without human involvement. Machine-to-machine communications are typically terse. Most sensors and actuators will report or act upon small pieces of information - "chirps". Burdening these devices with current network protocol stacks is inefficient, unnecessary and unduly increases their cost of ownership. This must change. The architecture of the Internet of Things must evolve now by incorporating simpler protocols toward at the edges of the network, or remain forever inefficient. Rethinking the Internet of Things describes reasons why we must rethink current approaches to the Internet of Things. Appropriate architectures that will coexist with existing networking protocols are described in detail. An architecture comprised of integrator functions, propagator nodes, and end devices, along with their interactions, is explored.
Rethinking Quaternions (Synthesis Lectures on Computer Graphics and Animation)
by Ron GoldmanQuaternion multiplication can be used to rotate vectors in three-dimensions. Therefore, in computer graphics, quaternions have three principal applications: to increase speed and reduce storage for calculations involving rotations, to avoid distortions arising from numerical inaccuracies caused by floating point computations with rotations, and to interpolate between two rotations for key frame animation. Yet while the formal algebra of quaternions is well-known in the graphics community, the derivations of the formulas for this algebra and the geometric principles underlying this algebra are not well understood. The goals of this monograph are to provide a fresh, geometric interpretation for quaternions, appropriate for contemporary computer graphics, based on mass-points; to present better ways to visualize quaternions, and the effect of quaternion multiplication on points and vectors in three dimensions using insights from the algebra and geometry of multiplication in the complex plane; to derive the formula for quaternion multiplication from first principles; to develop simple, intuitive proofs of the sandwiching formulas for rotation and reflection; to show how to apply sandwiching to compute perspective projections. In addition to these theoretical issues, we also address some computational questions. We develop straightforward formulas for converting back and forth between quaternion and matrix representations for rotations, reflections, and perspective projections, and we discuss the relative advantages and disadvantages of the quaternion and matrix representations for these transformations. Moreover, we show how to avoid distortions due to floating point computations with rotations by using unit quaternions to represent rotations. We also derive the formula for spherical linear interpolation, and we explain how to apply this formula to interpolate between two rotations for key frame animation. Finally, we explain the role of quaternions in low-dimensional Clifford algebras, and we show how to apply the Clifford algebra for R3 to model rotations, reflections, and perspective projections. To help the reader understand the concepts and formulas presented here, we have incorporated many exercises in order to clarify and elaborate some of the key points in the text.

Rethinking Law, Regulation, and Technology (Rethinking Law series)
by Roger BrownswordThis insightful book presents a radical rethinking of the relationship between law, regulation, and technology. While in traditional legal thinking technology is neither of particular interest nor concern, this book treats modern technologies as doubly significant, both as major targets for regulation and as potential tools to be used for legal and regulatory purposes. It explores whether our institutions for engaging with new technologies are fit for purpose.Having depicted a legal landscape that includes legal rules and principles, regulatory frameworks, technical measures and technological governance, this thought-provoking book presents further exercises in rethinking. These exercises confront communities with a fundamental question about how they are to be governed—by humans using rules or by technical measures and technological management? Chapters rethink the traditional arguments relating to legality, the rule of law, legitimacy, regulatory practice, dispute resolution, crime and control, and authority and respect for law. Examining the role of lawyers and law schools in an age of governance by smart technologies, Rethinking Law, Regulation, and Technology will be a key resource for students and scholars of law and technology, digital innovation and regulation and the law.

Rethinking ICT Adoption Theories in the Developing World: Information and Communication Technologies (Signals and Communication Technology)
by Emmanuel Eilu Ganesh Bhutkar Rehema Baguma John Sören PetterssonThis book provides extended frameworks and models to help with the adoption of information and communication technologies (ICT) in developing countries. The book first discusses the extent to which conventional ICT theories can be rigid in nature, often unable to handle the constant advances in technology, and technology adoption, implementation, usage, and disposal, not to mention different needs and cost availability in developing countries. The authors go on to show how new and revised models, tested in many societies in developing countries, can solve this mismatch. The authors provide examples of successful ICT adoption in developing country settings, in the areas of agriculture, culture, forestry, education, economics, health, and governance. The authors also show how techniques from persuasive design, philosophical designs, and motivational designs have been adjusted to facilitate successful ICT adoption, implementation, usage, and disposal in targeted regions.
Rethinking Hypermedia: The Microcosm Approach (Electronic Publishing Series #4)
by Wendy Hall Hugh Davis Gerard HutchingsRethinking Hypermedia: The Microcosm Approach is essentially the story of the Microcosm hypermedia research and development project that started in the late 1980's and from which has emerged a philosophy that re-examines the whole concept of hypermedia and its role in the evolution of multimedia information systems. The book presents the complete story of Microcosm to date. It sets the development of Microcosm in the context of the history of the subject from which it evolved, as well as the developments in the wider world of technology over the last two decades including personal computing, high-speed communications, and the growth of the Internet. These all lead us towards a world of global integrated information environments: the publishing revolution of the 20th century, in principle making vast amounts of information available to anybody anywhere in the world. Rethinking Hypermedia: The Microcosm Approach explains the role that open hypermedia systems and link services will play in the integrated information environments of the future. It considers issues such as authoring, legacy systems and data integrity issues, and looks beyond the simple hypertext model provided in the World Wide Web and other systems today to the world of intelligent information processing agents that will help us deal with the problems of information overload and maintenance. Rethinking Hypermedia: The Microcosm Approach will be of interest to all those who are involved in designing, implementing and maintaining hypermedia systems such as the World Wide Web by setting the groundwork for producing a system that is both easy to use and easy to maintain. Rethinking Hypermedia: The Microcosm Approach is essential reading for anyone involved in the provision of online information.

Rethinking Ethics Through Hypertext
by Dominic GarciaThis book considers how social justice and authentic freedom of speech could be better tackled through hypertextual writing. Unilinear writing produces an artificial understanding of justice, freedom of speech and hermeneutics. In contrast, hypertextual writing promises an optimistic future which involves less judgment, more empathy and the embracing of difference, so vital in our post-truth culture. The author argues that hypertextual writing is set to have a marked impact on fields like jurisprudence, social sciences and education. Rethinking Ethics Through Hypertext reconciles traditional theories of ethics by re-framing them through hypertextual techniques, bringing together contrasting and contradictory ethical views. It presents compelling insights for scholars of moral philosophy, social justice, hermeneutics and education.

Rethinking Cyber Warfare: The International Relations of Digital Disruption
by R. David EdelmanFifteen years into the era of ?cyber warfare,? are we any closer to understanding the role a major cyberattack would play in international relations - or to preventing one? Uniquely spanning disciplines and enriched by the insights of a leading practitioner, Rethinking Cyber Warfare provides a fresh understanding of the role that digital disruption plays in contemporary international security. Focusing on the critical phenomenon of major cyberattacks against wired societies, the book reconsiders central tenets that shaped global powers' policies and explains what forces in the international system might durably restrain their use. Arming the reader with the key technological and historical context to make sense of cyberattacks, it explores how deterrence, international law, and normative taboos operate today to shape whether and how states think about causing this kind of disruption - and how soon those forces might combine to rethink those decisions entirely. The result is a comprehensive look at one of the most pressing issues in international security that also illuminates a new pathway for managing one of its greatest sources of instability.

Rethinking Children's Play (New Childhoods)
by Fraser Brown Michael PatteRethinking Children's Play examines attitudes towards, and experiences of, children's play. Fraser Brown and Michael Patte draw on a wide range of thought, research and practice from different fields and countries to debate, challenge and re-appraise long held beliefs, attitudes and ways of working and living with children in the play environment.Children need to play and the benefits of play are many and varied, but they are too often underestimated by parents, educators, politicians and society in general. The authors apply a playwork perspective to a wide range of settings populated by children, both formal and informal, to explore the idea that children's learning and development derives substantially from their opportunities to engage with a rich play environment that is supportive of the play process.Thoughts are provoked through examples of research, reflections on research, activities, key points and guidance on further reading.Rethinking Children's Play is essential for all those studying childhood at undergraduate and graduate level and of great interest to those working with children in any field.
