Virtuality and Capabilities in a World of Ambient Intelligence
by Luiz CostaThis book is about power and freedoms in our technological world and has two main objectives. The first is to demonstrate that a theoretical exploration of the algorithmic governmentality hypothesis combined with the capability approach is useful for a better understanding of power and freedoms in Ambient Intelligence, a world where information and communication technologies are invisible, interconnected, context aware, personalized, adaptive to humans and act autonomously. The second is to argue that these theories are useful for a better comprehension of privacy and data protection concepts and the evolution of their regulation. Having these objectives in mind, the book outlines a number of theses based on two threads: first, the elimination of the social effects of uncertainty and the risks to freedoms and, second, the vindication of rights. Inspired by and building on the outcomes of different philosophical and legal approaches, this book embodies an effort to better understand the challenges posed by Ambient Intelligence technologies, opening paths for more effective realization of rights and rooting legal norms in the preservation of the potentiality of human capabilities.
Virtuality and Humanity: Virtual Practice and Its Evolution from Pre-History to the 21st Century
by Sam N. Lehman-WilzigThis is a pioneering study of virtuality through human history: ancient-to-modern evolution and recent expansion; expression in many fields (chapters on Religion; Philosophy, Math, Physics; Literature and the Arts; Economics; Nationhood, Government and War; Communication); psychological and social reasons for its universality; inter-relationship with "reality." The book's thesis: virtuality was always an integral part of humanity in many areas of life, generally expanding over the ages. The reasons: 1- brain psychology; 2- virtuality's six functions — escape from boredom to relieving existential dread. Other questions addressed: How will future neuroscience, biotech and "compunications" affect virtuality? Can/should there be limits to human virtualizing?

Virtualization: Big Picture of the Who, What, and Where of Virtualization
by Dan KusnetzkyWhat exactly is virtualization? As this concise book explains, virtualization is a smorgasbord of technologies that offer organizations many advantages, whether you're managing extremely large stores of rapidly changing data, scaling out an application, or harnessing huge amounts of computational power. With this guide, you get an overview of the five main types of virtualization technology, along with information on security, management, and modern use cases.Topics include:Access virtualization—Allows access to any application from any deviceApplication virtualization—Enables applications to run on many different operating systems and hardware platformsProcessing virtualization—Makes one system seem like many, or many seem like oneNetwork virtualization—Presents an artificial view of the network that differs from the physical realityStorage virtualization—Allows many systems to share the same storage devices, enables concealing the location of storage systems, and more
Virtualized Cloud Data Center Networks: Issues in Resource Management.
by Linjiun Tsai Wanjiun LiaoThis book discusses the characteristics of virtualized cloud networking, identifies the requirements of cloud network management, and illustrates the challenges in deploying virtual clusters in multi-tenant cloud data centers. The book also introduces network partitioning techniques to provide contention-free allocation, topology-invariant reallocation, and highly efficient resource utilization, based on the Fat-tree network structure. Managing cloud data center resources without considering resource contentions among different cloud services and dynamic resource demands adversely affects the performance of cloud services and reduces the resource utilization of cloud data centers. These challenges are mainly due to strict cluster topology requirements, resource contentions between uncooperative cloud services, and spatial/temporal data center resource fragmentation. Cloud data center network resource allocation/reallocation which cope well with such challenges will allow cloud services to be provisioned with predictable network performance, mitigate service performance degradation and even guarantee service level agreements. Virtualized Cloud Data Center Networks: Issues in Resource Management tackles the challenges of managing cloud data center networks and introduces techniques to efficiently deploy large-scale distributed computing applications that require predictable performance in multi-tenant cloud data centers.
Virtually Human: The Promise—and the Peril—of Digital Immortality
by Martine RothblattVirtually Human explores what the not-too-distant future will look like when cyberconsciousness—simulation of the human brain via software and computer technology—allows our consciousness to be present forever.Meet Bina48, the world's most sentient robot, commissioned by Martine Rothblatt and created by Hanson Robotics. Bina48 is a nascent Mindclone of Martine's wife that can engage in conversation, answer questions, and even have spontaneous thoughts that are derived from multimedia data in a Mindfile created by the real Bina. If you're active on Twitter or Facebook, share photos through Instagram, or blogging regularly, you're already on your way to creating a Mindfile—a digital database of your thoughts, memories, feelings, and opinions that is essentially a back-up copy of your mind. Soon, this Mindfile can be made conscious with special software—Mindware—that mimics the way human brains organize information, create emotions and achieve self-awareness. This may sound like science-fiction A.I. (artificial intelligence), but the nascent technology already exists. Thousands of software engineers across the globe are working to create cyberconsciousness based on human consciousness and the Obama administration recently announced plans to invest in a decade-long Brain Activity Map project. Virtually Human is the only book to examine the ethical issues relating to cyberconsciousness and Rothblatt, with a Ph.D. in medical ethics, is uniquely qualified to lead the dialogue.

Virtuelle Universität: Digitalisierung erfordert neue Lernparadigmen (Technik im Fokus)
by Dieter Beste Hartmut FreyDas Buch vermittelt das Konzept einer globalen, virtuellen Universität in Kombination mit neuen Erkenntnissen aus der Lernforschung. Hierbei werden mithilfe von künstlicher Intelligenz bewegungsorientierte, virtuelle 3-D-Bilder eingebunden. Dadurch wird die Lernbereitschaft und damit auch die Kreativität des Einzelnen angeregt. So werden bereits heute Schweißer in Großunternehmen mittels Datenbrille und intelligenter Avatare ausgebildet. Über eine virtuelle Universität lassen sich Forschungsprojekte initiieren und koordinieren. Problemlösungen lassen sich mit der Verwendung von Avataren in virtuellen Hörsälen erarbeiten. Die Zertifizierung erfolgt nicht mehr über das Abfragen von Wissensinhalten, sondern über die Fähigkeit Probleme zu lösen. Weitere wichtige Aspekte einer virtuellen Universität sind, im Vergleich zu den klassischen Universitäten, die geringen Kosten, die Möglichkeit bei der Entwicklung des Contents die besten Wissenschaftler zu beteiligen sowie die immer mehr um sich greifende Sekundär- und Tertiärforschung. Eine virtuelle Universität bietet die Chance der Emanzipation gesellschaftlicher Praxis von Wissenschaft durch Wissenschaft und Immunisierung gesellschaftlich geltende Ideologien und Interessenstandpunkte gegen wissenschaftliche Aufklärungsansprüche.
