Understanding Concurrent Systems
by A. W. RoscoeCSP notation has been used extensively for teaching and applying concurrency theory, ever since the publication of the text Communicating Sequential Processes by C.A.R. Hoare in 1985. Both a programming language and a specification language, the theory of CSP helps users to understand concurrent systems, and to decide whether a program meets its specification. As a member of the family of process algebras, the concepts of communication and interaction are presented in an algebraic style. An invaluable reference on the state of the art in CSP, Understanding Concurrent Systems also serves as a comprehensive introduction to the field, in addition to providing material for a number of more advanced courses. A first point of reference for anyone wanting to use CSP or learn about its theory, the book also introduces other views of concurrency, using CSP to model and explain these. The text is fully integrated with CSP-based tools such as FDR, and describes how to create new tools based on FDR. Most of the book relies on no theoretical background other than a basic knowledge of sets and sequences. Sophisticated mathematical arguments are avoided whenever possible. Topics and features: presents a comprehensive introduction to CSP; discusses the latest advances in CSP, covering topics of operational semantics, denotational models, finite observation models and infinite-behaviour models, and algebraic semantics; explores the practical application of CSP, including timed modelling, discrete modelling, parameterised verifications and the state explosion problem, and advanced topics in the use of FDR; examines the ability of CSP to describe and enable reasoning about parallel systems modelled in other paradigms; covers a broad variety of concurrent systems, including combinatorial, timed, priority-based, mobile, shared variable, statecharts, buffered and asynchronous systems; contains exercises and case studies to support the text; supplies further tools and information at the associated website: http://www.comlab.ox.ac.uk/ucs/. From undergraduate students of computer science in need of an introduction to the area, to researchers and practitioners desiring a more in-depth understanding of theory and practice of concurrent systems, this broad-ranging text/reference is essential reading for anyone interested in Hoare's CSP.

You’ll discover not only how to design for a given context, but also how design participates in making context.Learn how people perceive context when touching and navigating digital environmentsSee how labels, relationships, and rules work as building blocks for contextFind out how to make better sense of cross-channel, multi-device products or servicesDiscover how language creates infrastructure in organizations, software, and the Internet of ThingsLearn models for figuring out the contextual angles of any user experience
Understanding Control Flow
by Peter A. BuhrThe control-flow issues presented in this textbook are extremely relevant in modern computer languages and programming styles. In addition to the basic control-flow mechanisms, virtually all new computer languages provide some form of exceptional control flow to support robust programming introduced in this textbook. Also, concurrency capabilities are appearing with increasing frequency in both new and old programming languages, and are covered in this book. Understanding Control Flow: With Concurrent Programming Using μC++ starts with looping, and works through each of the basic control-flow concepts, examining why each is fundamental and where it is useful. Time is spent on each concept according to its level of difficulty. Examples and exercises are also provided in this textbook. New programming methodologies are requiring new forms of control flow, and new programming languages are supporting these methodologies with new control structures, such as the concurrency constructs discussed in this textbook. Most computers now contain multi-threading and multi-cores, while multiple processors and distributed systems are ubiquitous -- all of which require advanced programming methodologies to take full advantage of the available parallelism summarized in this textbook. Advance forms of control flow are becoming basic programming skills needed by all programmers, not just graduate stude nts working in the operating systems or database disciplines. This textbook is designed for advanced-level students studying computer science and engineering. Professionals and researchers working in this field, specifically programming and software engineering, will find this book useful as a reference.
Understanding Counterplay in Video Games (Routledge Advances in Game Studies)
by Alan MeadesThis book offers insight into one of the most problematic and universal issues within multiplayer videogames: antisocial and oppositional play forms such as cheating, player harassment, the use of exploits, illicit game modifications, and system hacking, known collectively as counterplay. Using ethnographic research, Alan Meades not only to gives voice to counterplayers, but reframes counterplay as a complex practice with contradictory motivations that is anything but reducible to simply being hostile to play, players, or commercial videogames. The book offers a grounded and pragmatic exploration of counterplay, framing it as an unavoidable by-product of interaction of mass audiences with compelling and culturally important texts.
Understanding Crypto Fundamentals: Value Investing in Cryptoassets and Management of Underlying Risks
by Thomas JeegersSaying that many investors were not convinced by cryptocurrencies in their first decade of existence would be an understatement. Originally, author Thomas Jeegers was one of them. He looked into this new virtual money more than once and, each time, decided not to invest. Like many long-term investors, he was looking for fundamentals. Crypto had none — or so he thought. This book details why his perspective on cryptoassets has shifted – and why yours should, too. Recent developments in this field have turned crypto from a speculative financial innovation to a new asset class, one with a new kind of fundamentals that offer real economic value. One that will change finance and investments. One that may be a trigger defining the fourth industrial revolution, the same way steam, electricity, and the Internet were triggers for the first, second, and third industrial revolutions, respectively. Despite what advocates of the traditional financial establishment like to claim, cryptoassets were by far the best financial investment of the last decade, even risk-adjusted, and could still be so for the coming one. They should not be overlooked, regardless of one’s opinion of them. This book answers the main questions any potential long-term investor in cryptoassets should ask: What are cryptoassets and blockchain technology?Why consider cryptoasset investments?When is a good time to invest?Where should one invest? How should one invest? Which valuation methods are appropriate? Understanding Crypto Fundamentals includes a deep dive into the management of risks specific to cryptoassets, both financial and non-financial, and provides the tools needed for investment success in this new asset class. Upon completing the book, you will have a new perspective on cryptoassets and how you can benefit from them as an investor.Thomas Jeegers is a CFA Charterholder and Financial Risk Manager (FRM), and has earned an MBA from INSEAD as well as multiple blockchain certifications from institutions including INSEAD and Oxford University. He has worked in finance for 10 years and is a frequent speaker at events on blockchain and cryptoassets.

Understanding Harmonic Propagation in Meshed Transmission Power Systems with a Large Number of Underground Cables: New Analytical Methods (Springer Theses)
by Bjarne Søndergaard BukhThis outstanding PhD thesis reports on new analytical methods developed to analyse harmonic propagation in large transmission systems. The focus is on understanding the physical relationships between harmonic propagation phenomena in the passive grid caused by grid expansions or changes to existing transmission lines. Principal component analysis and partial least squares regression have been used as tools to investigate statistical correlations between harmonic distortion levels at substations, and a harmonic propagation model based on standing wave phenomena and techniques known from radio and microwave theory has been developed. Knowledge of the propagation phenomena has also been used to develop a new method for determining appropriate locations for harmonic mitigating equipment in a grid. Finally, the methods have been validated through both simulation models and harmonic voltage measurements obtained from the Danish transmission grid. Overall, this thesis reports new insights into harmonic propagation in power systems as the use of underground cables increases and offers new tools for analysing such phenomena. No previous examples of data-driven analyses of measurement data from a power system in the form presented here could be found in existing literature, thus paving a way to new possibilities for this emerging field.
