The Heroes Return (Bounders #4)
by Monica TeslerJasper and Mira must escape the Rift and deliver the Youli’s message to Earth Force before it’s too late in this action-packed fourth novel in what Shannon Messenger calls the “richly detailed, highly imaginative” Bounders series!After escaping the Youli’s attack on Alkalinia, Jasper and Mira find themselves trapped with the lost aeronauts in the rift, a rip in space where time moves differently. For every minute they spend in the rift, they are losing days back home. Just when Jasper fears they’ll be stuck in limbo forever, the most unlikely ally shows up: the Youli. The Youli promise to rescue everyone in the rift, but their help comes at a price. First, Jasper must tell Earth Force that the Youli want peace. And second, Mira can’t return with Jasper. She has to leave with the Youli. Back home, almost a year has passed. The Youli war is public, Bounders are in space full-time, and Jasper’s pod is divided. Cole and Lucy have been promoted. Marco and Addy are missing. Jasper delivers the Youli’s message, but the admiral isn’t interested in peace talks. Instead, she sends Jasper and the aeronauts on a publicity tour of Earth to build support for the war. At first, Jasper revels in the spotlight. But it soon becomes clear that if Jasper doesn’t convince Earth Force to stop fighting—and soon—there won’t be an Earth left to fight for, and he may never see Mira again.
Heroes & Villains: Inside the minds of the greatest warriors in history
by Frank McLynnIn the history of warfare, an elite group of men have attained almost legendary status through their courage, ambition and unrivalled military genius. But many of these same men possessed deep personal character flaws. In Heroes & Villains, acclaimed historian Frank McLynn focuses on six of the most powerful and magnetic leaders of all time: Spartacus, Attila the Hun, Richard the Lionheart, Cortés, Tokugawa Ieyasu and Napoleon. How did these mortal men rise to positions of seemingly invincible power? What were the motives, the personal strengths and often weaknesses that drove them to achieve what no one else dared? In six powerful portraits, McLynn brilliantly evokes the critical moments when each of these warriors proved themselves in battle, changing their own lives, the destiny of their people and, in some cases, the history of the world. We discover what drove Spartacus to take on the might of Rome against seemingly impossible odds, and how the young Napoleon rose to power in dramatic fashion at the Siege of Toulon. Heroes & Villains is more than a collection of individual biographies. By examining the complex psychologies of these extraordinary men, McLynn builds up a convincing profile of the ultimate warrior. Accompanying a major BBC television series, this brilliant book takes us into the minds of the greatest warriors in history.
Herokiller: A Novel
by Paul Tassi“An incredible new voice in sci-fi. The kind of writer who keeps you turning the pages long into the night.”—A.G. Riddle, bestselling author of The Atlantis Gene and PandemicReady Player One meets Gladiator in this high-octane thriller that mixes black-ops espionage with fight-to-the-death combat in the arena. In the near future, the line between entertainment and brutality has blurred. Mysterious billionaire Cameron Crayton is a household name from televised spectacles in which prison inmates fight to the death, but his old shows pale in comparison to his new event, The Crucible, a gladiatorial tournament anyone can enter. The winner is promised unimaginable wealth and glory . . . if they’re able to survive a series of globally broadcast fight-to-the-death matches with medieval weaponry against the world’s most fearsome fighters. Former black-ops operative Mark Wei wants nothing more than to be left alone to drink after sacrificing everything?including his family?in America’s covert Cold War II against China, a war won largely because of him. But there are rumors that Crayton’s background and business dealings involve shady connections to foreign powers, and soon Mark is convinced to reluctantly dust off his training, strap on a sword and armor, and enter the tournament arena as an undercover agent. It’s the most dangerous assignment he’s ever been given, and Mark quickly finds himself not just fighting for his life in the arena against trained killers, but racing to expose The Crucible’s founder’s secrets while navigating a viral phenomenon in which the stakes are literally life and death. . . .
Herring: A History of the Silver Darlings
by Mike SmylieThe story of herring is entwined in the history of commercial fishing. For over two millennia, herring have been commercially caught and its importance to the coastal peoples of Britain cannot be measured. At one point tens of thousands were involved in the catching, processing and sale of herring. They followed the shoals around the coast from Stornoway to Penzance and many towns on Britain’s East Coast grew rich on the backs of the ‘silver darlings’. The book looks at the effects of the herring on the people who caught them, the unique ways of life, the superstitions of the fisher folk, their boats and the communities who lived for the silver darlings. With a wealth of illustrations, this fascinating book reveals the little-known history of the herring. And for those who’ve neglected the silver darlings for lesser fish such as cod and haddock, there are a number of mouth-watering recipes to try.
Herschel at the Cape: Diaries and Correspondence of Sir John Herschel, 1834-1838
by David S. Evans Terence J. Deeming Betty Hall Evans Stephen GoldfarbSir John Herschel, one of the founders of Southern Hemisphere astronomy, was a man of extraordinarily wide interests. He made contributions to botany, geology, and ornithology, as well as to astronomy, chemistry, and mathematics. Throughout his scientific career he kept a diary, recording his public and private life. The diaries from 1834 to 1838, years spent making astronomical observations at the Cape of Good Hope, are reproduced in this book and prove to be much more than an ordinary scientist''s logbook. They present personal and social history, literary commentaries, the results of close observations of nature and numerous scientific experiments, the excitement of travel, political intrigues, gossip, and philosophical reflections--all interpreted through an alert and versatile mind. In the present transcription, the material has been enriched with selected correspondence of Sir John and his wife Lady Herschel (neé Margaret Brodie Stewart). Sir John devoted his working time at the Cape primarily to a systematic observation of the southern sky, complementing his earlier "sweeping" of the northern sky at Slough, England. He later became one of the founders of photography, but at the Cape he used a simple optical device, the camera lucida, in the production of numerous landscape drawings. Many of these, along with reproductions of sketches contained in the diaries and botanical drawings made by Sir John and Lady Herschel, are used to illustrate this book. Sir John was also a leading spirit in the foundation of the educational system of the Cape and a supporter of exploratory expeditions into the interior. As the son of Sir William Herschel, in his day the most famous British astronomer and the discoverer of the planet Uranus, Sir John was already celebrated when he arrived from England. Every individual of note, resident at the Cape or visiting, went to see him. He was supported in his work by his wife, who ran an enormous establishment and bore a huge family, but who nevertheless found time to travel in the country round the western Cape with him and to assist in his observations. The diaries and letters are supplemented by especially valuable editorial notes that provide much needed and highly interesting information concerning persons and events mentioned and described by Sir John. All the original manuscript material used in this volume is held by the Harry Ransom Center at the University of Texas at Austin. Sir John''s camera lucida drawings are from the South African Public Library in Cape Town.

Hesitant Fuzzy Set: Theory and Extension (Computational Intelligence Methods and Applications)
by Bahram FarhadiniaCovering a wide range of notions concerning hesitant fuzzy set and its extensions, this book provides a comprehensive reference to the topic. In the case where different sources of vagueness appear simultaneously, the concept of fuzzy set is not able to properly model the uncertainty, imprecise and vague information. In order to overcome such a limitation, different types of fuzzy extension have been introduced so far. Among them, hesitant fuzzy set was first introduced in 2010, and the existing extensions of hesitant fuzzy set have been encountering an increasing interest and attracting more and more attentions up to now. It is not an exaggeration to say that the recent decade has seen the blossoming of a larger set of techniques and theoretical outcomes for hesitant fuzzy set together with its extensions as well as applications.As the research has moved beyond its infancy, and now it is entering a maturing phase with increased numbers and types of extensions, this book aims to give a comprehensive review of such researches. Presenting the review of many and important types of hesitant fuzzy extensions, and including references to a large number of related publications, this book will serve as a useful reference book for researchers in this field.
A Hetero-functional Graph Theory for Modeling Interdependent Smart City Infrastructure
by Wester C. Schoonenberg Inas S. Khayal Amro M. FaridCities have always played a prominent role in the prosperity of civilization. Indeed, every great civilization we can think of is associated with the prominence of one or more thriving cities. And so understanding cities -- their inhabitants, their institutions, their infrastructure -- what they are and how they work independently and together -- is of fundamental importance to our collective growth as a human civilization. Furthermore, the 21st century “smart” city, as a result global climate change and large-scale urbanization, will emerge as a societal grand challenge. This book focuses on the role of interdependent infrastructure systems in such smart cities especially as it relates to timely and poignant questions about resilience and sustainability. In particular, the goal of this book is to present, in one volume, a consistent Hetero-Functional Graph Theoretic (HFGT) treatment of interdependent smart city infrastructures as an overarching application domain of engineering systems. This work may be contrasted to the growing literature on multi-layer networks, which despite significant theoretical advances in recent years, has modeling limitations that prevent their real-world application to interdependent smart city infrastructures of arbitrary topology. In contrast, this book demonstrates that HFGT can be applied extensibly to an arbitrary number of arbitrarily connected topologies of interdependent smart city infrastructures. It also integrates, for the first time, all six matrices of HFGT in a single system adjacency matrix. The book makes every effort to be accessible to a broad audience of infrastructure system practitioners and researchers (e.g. electric power system planners, transportation engineers, and hydrologists, etc.). Consequently, the book has extensively visualized the graph theoretic concepts for greater intuition and clarity. Nevertheless, the book does require a common methodological base of its readers and directs itself to the Model-Based Systems Engineering (MBSE) community and the Network Science Community (NSC). To the MBSE community, we hope that HFGT will be accepted as a quantification of many of the structural concepts found in model-based systems engineering languages like SysML. To the NSC, we hope to present a new view as how to construct graphs with fundamentally different meaning and insight. Finally, it is our hope that HFGT serves to overcome many of the theoretical and modeling limitations that have hindered our ability to systematically understand the structure and function of smart cities.

Heterogeneous Networks in LTE-Advanced
by Joydeep Acharya Long Gao Sudhanshu GaurA comprehensive summary of theoretical and practical developments in LTE Heterogeneous Networks The last decade has witnessed the proliferation of mobile broadband data and the trend is likely to increase in the coming years. Current cellular networks are ill equipped to deal with this surge in demand. To satisfy user demand and maximize profits, a new paradigm to operate networks is needed. Heterogeneous networks, that deploy an overlay of small cells with limited coverage and transmit power, over a macro coverage area is the solution by providing capacity and coverage where it is needed. This book presents a comprehensive overview of small cell based heterogeneous networks within the framework of 3GPP LTE-Advanced which is the major enabler of current and future heterogeneous networks. The book first establishes the basics of LTE standards 8 -10. Wherever relevant, the underlying theory of wireless communications is explained and the signaling and protocol aspects of LTE Releases 8-10 are presented. Next the book presents a systematic study of the inter cell interference (eICIC and FeICIC) mechanisms that have been standardized in LTE releases 10 and 11 to mitigate the interference arising in heterogeneous networks. From simple blank subframe design and implementation, the book discusses more advanced transceiver signal processing and carrier aggregation (CA) based mechanisms to improve performance. Besides data, control channel enhancements such as enhanced PDCCH (ePDCCH) are also discussed. Subsequently the book discusses the possibility of base stations being allowed to coordinate to manage interference. This technique, called CoMP, has the potential of vastly improving network performance. However several practical challenges first have to be overcome before this potential can be realized. The book presents the different CoMP categories introduced in LTE release 11, the required signal processing and the changes that were introduced in Release-11 for supporting CoMP. The book then presents the state of the art developments in heterogeneous networks that are currently taking place in 3GPP with the initiation of Release 12. A whole array of new technologies have been introduced such as dynamic switching of small cells, new carrier types with reduced control signaling, dynamic reconfiguration of TDD-LTE, joint configuration of TDD and FDD via carrier aggregation and lastly advanced MIMO signal processing with three dimensional beamforming. All these technologies will work in unison leading to efficient operations of small cells. The authors thus comprehensively summarize the advances in heterogeneous networks over the last couple of years as reflected in various LTE releases and then look ahead at what to expect in the future. Fully illustrated throughout and with an accompanying website including Matlab code for simulating heterogeneous networks, LTE channel models, and References to 3GPP specifications, contributions, and updates on recent standardization activities. The authors, being involved in LTE standardization, are well placed to give an excellent view on this topic, including valuable background and design rationale. A comprehensive summary of wireless communications theory and practical developments in LTE heterogeneous networks. Authors are experts in this field and are active members in standardization proceedings, enabling up-to-date coverage of current developments Multiple case studies explain network design optimization of various heterogeneous network deployments. Accompanying website includes Matlab code for simulating heterogeneous networks, LTE channel models, and References to 3GPP specifications, contributions, and updates on recent standardization activities Essential reading for Engineers and practitioners in wireless industry.
