Free Download Bill Gunston - Aircraft of World War II Chancellor Press | 1997 | ISBN: 1851528652 | English | 216 pages | PDF | 201.53 MB 600 detailed illustrations, 40 different aircraft described in detail.  Free Download Aircraft Cryogenics (International Cryogenics Monograph Series) by Ernst Wolfgang Stautner, Kiruba S. Haran, Phillip J. Ansell English | October 26, 2024 | ISBN: 3031714075 | 356 pages | EPUB | 95 Mb This book gives a step-by-step approach to the design of a cryogenic infrastructure required for superconducting, all-electric aircraft systems which is also partially applicable to liquid hydrogen fueled subsonic and hypersonic aircraft, as well as hybrids. While there is no shortage of publications on hydrogen fueled aircraft, this book puts the past journal literature through a magnifying glass and condenses it into an engineering strategy for the next steps to enable liquid hydrogen storage and distribution in aircraft. Emphasis is placed on tank design, manufacturability, safety features, and minimum tank weight, providing a holistic focus on the logistics of hydrogen management for all major components within the aircraft as well as on future superconducting motor architecture. The intention is to fully exploit the benefits of a liquid hydrogen reservoir without any need for additional cryogenic fluids, with relevance to cooling of various superconducting components e.g., motors and superconducting cables, as well as the heat sinking of power electronics and for fueling the fuel cell stack system. A liquid hydrogen tank hold-time analysis reveals the main governing factors and describes the required efforts for minimizing onboard boil off for aircraft designs with different flight mission duration. This is followed by an outlook showing where cryotankage technology and cryogenic aircraft architecture may move within the next 20 years embedded in a green hydrogen-based economy and how basic research will need to play a major role to help us realizing these future designs by consequently eliminating whitespace within today's technology landscape. This book is also an aircraft engineering resource on composites, hydrogen properties, general aircraft materials and safety.  Free Download Bruce Robertson - Aircraft Camouflage and Markings 1907-1954 Harleyford Publications | 1956 | ISBN: 0816863555 | English | 213 pages | PDF | 194.75 MB Aircraft Camouflage and Markings, 1907-1954 by Bruce Robertson is a definitive study of the subject as well as likely the first such book to be published. Arranged in chronological order by country, the author presents the technical side of aircraft insignia in terms of the specifications issued with an very good set of examples in the form of photgraphs, black and white drawings and some excellent color plates.  Free Download Agro-Environmental Sustainability in MENA Regions by Mohamed Abu-hashim English | EPUB | 2021 | 452 Pages | ISBN : 3030785734 | 101.2 MB  Free Download Henry Buller, Geoff Wilson, Andrea Holl, "Agri-environmental Policy in the European Union" English | 2019 | ISBN: 1138700991 | EPUB | pages: 310 | 5.5 mb This title was first published in 2000: This volume provides a detailed examination of agri-environmental policy within ten European states. Individual chapters consider the agricultural and environmental policy contexts within each state and examine the range and significance of agri-environmental policy proposed in addition to their spatial and territorial impact, their policy-making implications and their consequences for the structures, institutions and actors of national farming policy both across and within national borders. Drawing from ten national profiles and the data sets provided, the book provides a comparative analysis of implementation trends, filling a gap in the literature on this topic. Taking European legislation as its starting point, the comparative section of the book examines how Member States have responded to EU imperatives in their budgetary commitments, in their implementation strategies and in the policy outputs that result. The study identifies similarities across European nations in the territorial and agricultural focus of agri-environmental policy and draws attention to the alternative.  Free Download Aging Well with Diabetes: A 10-Point Action Plan for Older Adults (A Johns Hopkins Press Health Book) by Medha Munshi, Sheri Colberg English | April 29, 2025 | ISBN: 1421451522 | 368 pages | PDF | 8.24 Mb An essential guide to navigating diabetes for older adults and their caregivers.  Free Download Agentic AI in Enterprise: Harnessing Agentic AI for Business Transformation English | 2025 | ASIN: B0F44VF26B | 425 Pages | PDF EPUB (True) | 6.4 MB This book delves into the transformative power of Enterprise Agentic AI, tracing its evolution from basic automation to intelligent agents capable of contextual reasoning, memory retention, and autonomous decision-making. It provides a strategic roadmap for enterprises looking to integrate Agentic AI seamlessly into their operations while ensuring scalability, efficiency, and security.  Free Download Agentic AI in Enterprise: Harnessing Agentic AI for Business Transformation English | 2025 | ISBN: 9798868815416 | 407 pages | PDF | 7.69 MB This book delves into the transformative power of Enterprise Agentic AI, tracing its evolution from basic automation to intelligent agents capable of contextual reasoning, memory retention, and autonomous decision-making.

Free Download AgeTech for Staying Connected English | 2025 | ISBN: 3031870301 | 138 Pages | PDF EPUB (True) | 39 MB This book is a brief introductory guide to the role AgeTech plays in staying connected in later life. It offers insight into current AgeTech research on staying connected and illustrates entry points for deploying such technologies through a range of personas and scenarios capturing the common circumstances that lead older people to become disconnected, lonely, and isolated. The book provides readers with an accessible resource for understanding what sorts of AgeTech are available, what developments have been made and are currently underway, and what evidence exists for current technologies. The rapid pace of development in AgeTech, particularly in the commercial sphere, along with the competing claims being made for the benefits of many items, makes this practical guidebook essential for researchers and developers, policymakers, service providers and caregivers, and older adults themselves. While not intended to be exhaustive, this book covers basic information on common obstacles and barriers to technology development and adoption, things to keep in mind when using technology, and making the most of what is available to support older adults in staying connected.  Free Download After the Dinosaurs: The Age of Mammals (Life of the Past) by Donald R. Prothero English | July 13, 2006 | ISBN: 0253347335 | 392 pages | PDF | 63 Mb Perhaps nudged over the evolutionary cliff by a giant boloid striking the earth, the incredible and fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially the mammals, which in their way were every bit as remarkable as their Mesozoic cousins. |
