Evaluating IT Projects (Routledge Focus on Business and Management)
by Eriona ShtëmbariProject management disciplines have been a part of IT for many years. Why then, are so many challenges still directly associated with how a project is managed? Many projects fail for a myriad of reasons; most, however, stem from poor or inadequate project evaluation and performance appraisal, while, improved project planning and direction is considered to be one of the key factors to IT project success. Eriona Shtembari arranges evaluation methods and techniques into three groups, managerial-financial-and-development. This book explores the process of project evaluation and the purposes of evaluation, given its strong relationship to the success of the project. It examines IT project evaluation; identifies methods and techniques to be used throughout the project life cycle; examines the benefits of project evaluation and proposes a systematic approach/framework of project evaluation to serve as a tool for successful project management. <P><P>Shtembari analyses the most up-to-date research relating to the process and methods/techniques of project evaluation, throughout the project life cycle. From the systematic literature review, she identifies the most usable methods and techniques in project evaluation and focuses on the adequacy of these methods and techniques in the service sector. The theoretical underpinning of the book, serves as a base to interpret the interviews in the case study and build a theory as to how the project evaluation context relates to the proposed scientific theory. The findings in this book provide solutions for practitioners to help them boost the evaluation framework and consequently improve their IT project management.

Evolution of Air Interface Towards 5G
by Suvra Sekhar DasOver the past few decades, wireless access networks have evolved extensively to support the tremendous growth of consumer traffic. This superlative growth of data consumption has come about due to several reasons, such as evolution of the consumer devices, the types of telephone and smartphone being used, convergence of services, digitisation of economic transactions, tele-education, telemedicine, m-commerce, virtual reality office, social media, e-governance, e-security, to name but a few.Not only has the society transformed to a digital world, but also the expectations from the services provided have increased many folds. The last mile/meters of delivery of all e-services is now required to be wireless. It has always been known that wireless links are the bottleneck to providing high data rates and high quality of service. Several wireless signalling and performance analysis techniques to overcome the hurdles of wireless channels have been developed over the last decade, and these are fuelling the evolution of 4G towards 5G. Evolution of Air Interface Towards 5G attempts to bring out some of the important developments that are contributing towards such growth.

by Marco Bohr Basia SliwinskaThis volume addresses the evolution of the visual in digital communities, offering a multidisciplinary discussion of the ways in which images are circulated in digital communities, the meanings that are attached to them and the implications they have for notions of identity, memory, gender, cultural belonging and political action. Contributors focus on the political efficacy of the image in digital communities, as well as the representation of the digital self in order to offer a fresh perspective on the role of digital images in the creation and promotion of new forms of resistance, agency and identity within visual cultures.
Evolutionary Algorithms, Swarm Dynamics and Complex Networks
by Ivan Zelinka Guanrong ChenEvolutionary algorithms constitute a class of well-known algorithms, which are designed based on the Darwinian theory of evolution and Mendelian theory of heritage. They are partly based on random and partly based on deterministic principles. Due to this nature, it is challenging to predict and control its performance in solving complex nonlinear problems. Recently, the study of evolutionary dynamics is focused not only on the traditional investigations but also on the understanding and analyzing new principles, with the intention of controlling and utilizing their properties and performances toward more effective real-world applications. In this book, based on many years of intensive research of the authors, is proposing novel ideas about advancing evolutionary dynamics towards new phenomena including many new topics, even the dynamics of equivalent social networks. In fact, it includes more advanced complex networks and incorporates them with the CMLs (coupled map lattices), which are usually used for spatiotemporal complex systems simulation and analysis, based on the observation that chaos in CML can be controlled, so does evolution dynamics. All the chapter authors are, to the best of our knowledge, originators of the ideas mentioned above and researchers on evolutionary algorithms and chaotic dynamics as well as complex networks, who will provide benefits to the readers regarding modern scientific research on related subjects.
Evolutionary Approach to Machine Learning and Deep Neural Networks: Neuro-Evolution and Gene Regulatory Networks
by Hitoshi IbaThis book provides theoretical and practical knowledge about a methodology for evolutionary algorithm-based search strategy with the integration of several machine learning and deep learning techniques. These include convolutional neural networks, Gröbner bases, relevance vector machines, transfer learning, bagging and boosting methods, clustering techniques (affinity propagation), and belief networks, among others. The development of such tools contributes to better optimizing methodologies. Beginning with the essentials of evolutionary algorithms and covering interdisciplinary research topics, the contents of this book are valuable for different classes of readers: novice, intermediate, and also expert readers from related fields.Following the chapters on introduction and basic methods, Chapter 3 details a new research direction, i.e., neuro-evolution, an evolutionary method for the generation of deep neural networks, and also describes how evolutionary methods are extended in combination with machine learning techniques. Chapter 4 includes novel methods such as particle swarm optimization based on affinity propagation (PSOAP), and transfer learning for differential evolution (TRADE), another machine learning approach for extending differential evolution. The last chapter is dedicated to the state of the art in gene regulatory network (GRN) research as one of the most interesting and active research fields. The author describes an evolving reaction network, which expands the neuro-evolution methodology to produce a type of genetic network suitable for biochemical systems and has succeeded in designing genetic circuits in synthetic biology. The author also presents real-world GRN application to several artificial intelligent tasks, proposing a framework of motion generation by GRNs (MONGERN), which evolves GRNs to operate a real humanoid robot.

Exascale Scientific Applications: Scalability and Performance Portability (Chapman & Hall/CRC Computational Science)
by Timothy J. Williams Tjerk P. Straatsma Katerina B. AntypasFrom the Foreword: "The authors of the chapters in this book are the pioneers who will explore the exascale frontier. The path forward will not be easy... These authors, along with their colleagues who will produce these powerful computer systems will, with dedication and determination, overcome the scalability problem, discover the new algorithms needed to achieve exascale performance for the broad range of applications that they represent, and create the new tools needed to support the development of scalable and portable science and engineering applications. Although the focus is on exascale computers, the benefits will permeate all of science and engineering because the technologies developed for the exascale computers of tomorrow will also power the petascale servers and terascale workstations of tomorrow. These affordable computing capabilities will empower scientists and engineers everywhere."— Thom H. Dunning, Jr., Pacific Northwest National Laboratory and University of Washington, Seattle, Washington, USA "This comprehensive summary of applications targeting Exascale at the three DoE labs is a must read."— Rio Yokota, Tokyo Institute of Technology, Tokyo, Japan "Numerical simulation is now a need in many fields of science, technology, and industry. The complexity of the simulated systems coupled with the massive use of data makes HPC essential to move towards predictive simulations. Advances in computer architecture have so far permitted scientific advances, but at the cost of continually adapting algorithms and applications. The next technological breakthroughs force us to rethink the applications by taking energy consumption into account. These profound modifications require not only anticipation and sharing but also a paradigm shift in application design to ensure the sustainability of developments by guaranteeing a certain independence of the applications to the profound modifications of the architectures: it is the passage from optimal performance to the portability of performance. It is the challenge of this book to demonstrate by example the approach that one can adopt for the development of applications offering performance portability in spite of the profound changes of the computing architectures."— Christophe Calvin, CEA, Fundamental Research Division, Saclay, France "Three editors, one from each of the High Performance Computer Centers at Lawrence Berkeley, Argonne, and Oak Ridge National Laboratories, have compiled a very useful set of chapters aimed at describing software developments for the next generation exa-scale computers. Such a book is needed for scientists and engineers to see where the field is going and how they will be able to exploit such architectures for their own work. The book will also benefit students as it provides insights into how to develop software for such computer architectures. Overall, this book fills an important need in showing how to design and implement algorithms for exa-scale architectures which are heterogeneous and have unique memory systems. The book discusses issues with developing user codes for these architectures and how to address these issues including actual coding examples.’ — Dr. David A. Dixon, Robert Ramsay Chair, The University of Alabama, Tuscaloosa, Alabama, USA

It has the ability to deliver step-change benefits to organisations and enables forward-thinking CEOs to rethink their business models or create completely new businesses. But most of the real value of AI is hidden behind marketing hyperbole, confusing terminology, inflated expectations and dire warnings of 'robot overlords'. Any business executive that wants to know how to exploit AI in their business today is left confused and frustrated. As an advisor in Artificial Intelligence, Andrew Burgess regularly comes face-to-face with business executives who are struggling to cut through the hype that surrounds AI. The knowledge and experience he has gained in advising them, as well as working as a strategic advisor to AI vendors and consultancies, has provided him with the skills to help business executives understand what AI is and how they can exploit its many benefits. Through the distilled knowledge included in this book business leaders will be able to take full advantage of this most disruptive of technologies and create substantial competitive advantage for their companies.
Experience on Demand: What Virtual Reality Is, How It Works, and What It Can Do
by Jeremy BailensonAn in-depth look at virtual reality and how it can be harnessed to improve our everyday lives. Virtual reality is able to effectively blur the line between reality and illusion, pushing the limits of our imagination and granting us access to any experience imaginable. With well-crafted simulations, these experiences, which are so immersive that the brain believes they’re real, are already widely available with a VR headset and will only become more accessible and commonplace. But how does this new medium affect its users, and does it have a future beyond fantasy and escapism? In Experience on Demand, Jeremy Bailenson draws on two decades spent researching the psychological effects of VR and other mass media to help readers understand this powerful new tool. He offers expert guidelines for interacting with VR and describes the profound ways this technology can be put to use—not to distance ourselves from reality, but to enrich our lives and influence us to treat others, the environment, and even ourselves better. In the world of VR, a football quarterback plays a game against a competing team hundreds of times before even stepping onto the field; members of the United Nations embody a young girl in a refugee camp going through her day-to-day life; and veterans once again walk through the streets where they had experienced trauma. There are dangers and many unknowns in using VR, but it also can help us hone our performance, recover from trauma, improve our learning and communication abilities, and enhance our empathic and imaginative capacities. Like any new technology, its most incredible uses might be waiting just around the corner. Experience on Demand is the definitive look at the risks and potential of VR—a must-read for navigating both the virtual and the physical worlds ahead.
