A comprehensive guide to the modelling and design of solid oxide fuel cell hybrid power plantsThis book explores all technical aspects of solid oxide fuel cell (SOFC) hybrid systems and proposes solutions to a range of technical problems that can arise from component integration. Following a general introduction to the state-of-the-art in SOFC hybrid systems, the authors focus on fuel cell technology, including the components required to operate with standard fuels. Micro-gas turbine (mGT) technology for hybrid systems is discussed, with special attention given to issues related to the coupling of SOFCs with mGTs. Throughout the book emphasis is placed on dynamic issues, including control systems used to avoid risk conditions.With an eye to mitigating the high costs and risks incurred with the building and use of prototype hybrid systems, the authors demonstrate a proven, economically feasible approach to obtaining important experimental results using simplified plants that simulate both generic and detailed system-level behaviour using emulators. Computational models and experimental plants are developed to support the analysis of SOFC hybrid systems, including models appropriate for design, development and performance analysis at both component and system levels. Presents models for a range of size units, technology variations, unit coupling dynamics and start-up and shutdown behavioursFocuses on SOFCs integration with mGTs in light of key constraints and risk avoidance issues under steady-state conditions and during transient operationsIdentifies interaction and coupling problems within the GT/SOFC environment, including exergy analysis and optimizationDemonstrates an economical approach to obtaining important experimental results while avoiding high-cost components and risk conditionsPresents analytical/computational and experimental tools for the efficient design and development of hardware and software systemsHybrid Systems Based on Solid Oxide Fuel Cells: Modelling and Design is a valuable resource for researchers and practicing engineers involved in fuel cell fundamentals, design and development. It is also an excellent reference for academic researchers and advanced-level students exploring fuel cell technology.

'Exceptional debut' - Tommy Orange, New York Times David has a mind that never stops running. He reads Dante and Moby Dick, he sinks into Hemingway and battles with Milton. But on Florida's Gulf Coast, one can slip into deep water unconsciously.At the age of fourteen, David runs away from home to pursue a girl. He tries crack cocaine for the first time and is hooked instantly. Over the course of the next decade, he fights his way out of jail and rehab, trying to make sense of the world around him - a sunken world where faith in anything is a privilege. He makes his way to a tenuous sobriety, but it isn't until he takes a literature class at a community college that something within him ignites.All Day is a Long Time is a spectacular, raw account of growing up and managing, against the odds, to carve out a place for hope. David Sanchez's debut resounds with real force and demonstrates the redemptive power of the written word.

This is raw, semi-autobiographical fiction at its most painfully honest' Observer'Brilliant, lyrical, hilarious, heartbreaking' Cristina GarcíaDavid is only fourteen when he first tries crack cocaine. He is instantly hooked, and spends the next decade fighting his way out of jail and rehab. Though he reaches a tenuous sobriety, it is only when he takes a literature class at the local community college that something within him ignites.Set on Florida's Gulf Coast, All Day Is a Long Time is a spectacular account of what it takes to return from the brink to the world around us. In this unforgettable debut, David Sanchez demonstrates the importance of hope, and the redemptive power of the written word.'A wonder, an important, essential new voice' Justin Torres

we also explore the links between anonymization methods and privacy models (how anonymization methods can be used to enforce privacy models and thereby offer ex ante privacy guarantees).

This book explores the theoretical foundations of co-utility as well as its application to a number of areas, including distributed reputation management, anonymous keyword search, collaborative data anonymization, digital oblivion, peer-to-peer (P2P) content distribution, ridesharing for sustainable mobility, environmental economy, business model design and the collaborative economy. It evolved from presentations at the 1st Co-Utility Workshop, "held in Tarragona, Spain, on March 10–11, 2016."How can we guarantee that a global society without a common legal framework operates smoothly? If generosity, honesty and helpfulness do not arise spontaneously, one approach would be to design transactions so that helping others remains the best rational option. This is precisely the goal of co-utility, which can be defined in game-theoretic terms as any interaction between peers in which the best option for a player to maximize her or his utility is to make sure the other players also enjoy a fair share of utility (for example, functionality, security or privacy). Therefore, a protocol or mechanism designed using the co-utility principle ensures that helping others is the best rational option, even if players are selfish.
