Описание: Screens are ubiquitous today. Yet contemporary screen media eliminate the presence of the screen and diminish the visibility of its boundaries. As the image becomes indistinguishable from the viewer’s surroundings, this unsettling prompts re.examination of how screen boundaries demarcate. Through readings of three media forms – Virtual Reality; holograms; and light projections – this book develops new theories of the surfaces on and spaces in which images are displayed. Interrogating contemporary contestations of reality against illusion, it argues that the disappearance of difference reflects shifted conditions of actuality and virtuality in understanding the human condition. These shifts further connect to the current state of politics by way of their distorted truth values, corrupted terms of information, and internalizations of difference. The Post.Screen Through Virtual Reality, Holograms and Light Projections thus thinks anew the image’s borders and delineations, evoking the screen boundary as an instrumentation of today’s intense virtualizations which do not tell the truth. In the process, a new imagination for images emerges for a gluttony of the virtual; for new conceptualizations of object and representation, materiality and energies, media and histories, real and unreal; for new understandings of appearances, dis-appearances, replacement and re.placement – the post-screen.
The book is intended as a detailed guide to use and evaluate the modern digital technology to build modern PET systems. Digital Positron Emission Tomography represents the most modern trend among non-invasive functional nuclear imaging techniques. The term digital is interpreted both in terms of hardware configuration and in terms of data stream analysis. Modern miniaturized sensors realized in Complementary Metal Oxide Semiconductor technology allow to reduce the physical size of detecting pixels to the sub-millimetric range. The new Multi Voltage Threshold method allows to digitize the signals from each pixel within few hundred picoseconds and to collect digital data for further analysis. The modern concept of digital PET requires new techniques of digital data analysis and physical interpretation based on high performance computing platforms, and requires also to define new methods and strategies for the verification of the medical product quality standards.
The book will describe the physical fundaments of a novel sensor, the MVT SiPM, able to detect single photons with a space resolution of 50 um and a time resolution of few tens of picosecods. We will describe the physical processes and we will show how to correctly simulate and understand its features. We will show how to design a Positron Emission Tomography system based on this sensor, including high performance computing and artificial intelligence approach as techniques for the new generation digital PET systems. The book will make clear the physical and mathematical fundaments of the digital innovation introduced by this new sensor.
Описание: This book focuses on developing alignment as the foundation for a successful digital enterprise.
Over the last decade, digital technology has made deep inroads into every walk of life, but perhaps nowhere more than in the world of business. Technology now plays an enhanced role in driving business success, creating an entirely new paradigm in which business and technology are inseparable. Enterprises must ride the digital wave without losing their grip on the business basics to stay afloat. In this environment, business outcome is heavily dependent on the close alignment between business and technology.
Aligning Technology with Business for Digital Transformation is a guide to discovering the power of business-technology alignment. Gleaned from decades of experience with global corporations that have shaped the current business-technology landscape, it covers an indispensable organizational requirement in a simple and relatable way.
The book focuses on developing alignment as the foundation for a successful digital enterprise. Interlaced with real-life examples and anecdotes, it should help not only organizations in unlocking their true potential but also individuals in building the skills and aptitude necessary for succeeding in the digital world.
Описание: Arabic script is one of the world`s most widely used writing systems, for Arabic and non-Arabic languages alike. J. R. Osborn traces its evolution from the earliest inscriptions to digital fonts, from calligraphy to print and beyond. Students of communication, contemporary practitioners, and historians will find this narrative enlightening.
In the 21st Century no business or government will make decisions without relying on digital information. Can you trust the information you use to make decisions? Can your decisions be trusted by others?
Trust is under attack, making every decision more vulnerable. This is equally true for customers and for each of us in our daily decisions--without trust, spending and other investments shift to other options.
To achieve digital trust, Jeffrey Ritter explored the essence of trust itself. He discovered something remarkable--trust is a calculated decision, not an emotion. That simple truth required a new way to think differently about trust, especially digital trust, and ignited the author to create and build something new, rather than merely patch the status quo.
Described by executives in the opening pages as "essential reading for corporate executives," "ground-breaking," "fascinating," and a book that "will transform the dialogue about governance in a digital world," Achieving Digital Trust boldly declares risk management dead as a business discipline and offers, instead, an integrated strategy for building something new--digital trust.
Woven across a story of two fictional global competitors battling to survive and prosper, Ritter introduces a complete, integrated portfolio of tools he created to help business executives, IT strategists, and innovation leaders survive and excel in our digital world:
- A Trust Vocabulary-a shared lexicon of new phrases and terms, and new meanings for existing words, that enable discussion of trust decisions and increase efficiency of trust calculations.
- The Trust Decision Model-an integrated view of the sequential decision points and information layers that link together the steps taken when deciding whether or not to trust, and builds a bridge between human and computational trust.
- The Rules for Composing Rules-a set of fundamental principles for authoring effective rules for crossing the chasm between the ambiguity of broad, governing formal rules and the binary precision of executable software code.
- The Unified Rules Model-a new architecture for organizing the complexity of business, technology, and legal rules into unified, functional structures supporting the design and execution of digital systems that deliver compliance and earn our trust.
- The Unified Information Model-a new framework for organizing and designing digital information assets that result in more effective trust decisions and enhanced governance.
- The Digital Trust Design Principles-a framework for choosing among priorities and trade-offs to focus resources appropriately and improve desired outcomes.
- The Trust Prism-an entirely new, 3-D, visual tool for designing, building, and governing complex information systems, including in the Cloud . . . and more.
Together, these are a complete tool-kit that will change how leaders and executives make decisions that matter, build digital assets that can be trusted, and visualize and manage the complexity of their companies and the wired ecosystems in which they compete.

Описание: Cinema has been undergoing a profound technological shift: celluloidfilm is being replaced by digital media. In From Light to Byte MarkosHadjioannou asks what is different in the way digital movies depict theworld and engage with the individual and how we might best address the technological shift within media archaeologies.
Описание: "Venter instills awe for biology as it is, and as it might become in our hands." --Publishers Weekly On May 20, 2010, headlines around the world announced one of the most extraordinary accomplishments in modern science: the creation of the world's first synthetic lifeform. In Life at the Speed of Light, scientist J. Craig Venter, best known for sequencing the human genome, shares the dramatic account of how he led a team of researchers in this pioneering effort in synthetic genomics--and how that work will have a profound impact on our existence in the years to come. This is a fascinating and authoritative study that provides readers an opportunity to ponder afresh the age-old question "What is life?" at the dawn of a new era of biological engineering.
