Book Description
The Book The behaviour of helicopters and tiltrotor aircraft is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first and second editions of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented, relating to both normal and degraded Flying Qualities. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. In this third edition, two new Chapters are included. Chapter 9 takes the reader on a journey from the origins of the story of Flying Qualities, tracing key contributions to the developing maturity and to the current position. Chapter 10 provides a comprehensive treatment of the Flight Dynamics of tiltrotor aircraft; informed by research activities and the limited data on operational aircraft. Many of the unique behavioural characteristics of tiltrotors are revealed for the first time in this book. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing practice on the other. Checking predictions in flight requires clearly defined mission tasks, derived from realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities of rotorcraft forms the subject of this book, which will be of interest to engineers practising and honing their skills in research laboratories, academia and manufacturing industries, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.

Book Description
Göttinger Monograph N offers an unparalleled view into the early days of helicopter development, where Germany initially led technical innovation. Following World War II, the British Ministry of Supply ordered the German aeronautical research establishments in Göttingen (AVA) and Braunschweig (DFL) to summarize aeronautical research results obtained from 1939 to 1945 in a series of monographs. Göttinger Monograph N was the only of these documents to describe the development, of rotary-wing aircraft. Originally prepared under the direction of Albert Betz by Gerhard Sissingh and O.H. Nagel, the German-language document, now publicly available for the first time entirely in English, has been edited and translated by Berend G. van der Wall. Göttinger Monograph N describes German helicopter and autogyro development, highlighting the involvement of Henrich Focke, Anton Flettner, Friedrich von Doblhoff, and others who brought rotorcraft into series production maturity. It features aircraft including the Fw-61, the Fa-223, the Fa-230, the Fl-339, and more. It explores such areas as testing and accidents, Glauert-Lock-Wheatley's rotary-wing theory, performance investigations, and flying qualities. This unique historical and scientific contribution belongs on the shelf of anyone who seeks to understand the early engineering concepts that underlay the development of rotary-wing aircraft.

Book Description
The theory of natural pedagogy provides a model of social learning based on the direct communicative ostensive relation and aimed to the transfer of generic cultural knowledge. The pedagogical transmission of information originates from an explicit manifestation of teaching made by knowledgeable adults, who are naturally inclined to manifestly provide their cultural baggage to naïve conspecifics. The domain of transferable knowledge encompasses artifact functions, novel means actions, first words, gestural symbols, social practices, and rituals. This teaching process can be fast and efficient in virtue of a natural inclination possessed by infants to seek information and decode signals of ostensive communication. In this sense, the natural pedagogy represents, as the two proponents – György Gergey and Gergely Csibra – claim, «a communicative system of mutual design specialized for the fast and efficient transfer of new and relevant cultural knowledge from knowledgeable to ignorant conspecifics». This book suggests that natural pedagogy utilises early belief attribution competences, which are employed by infants in a variety of contexts to approach and navigate the social world. Therefore, the natural pedagogy, in cooperation with the early mindreading system, may represent one of the most efficient adaptive strategies to firmly create that deep wittgensteinian «nest of propositions» which build cultural shared beliefs structures to be relied upon and followed.

Book Description
The nEU-Med project is part of the Horizon 2020 programme, in the ERC Advanced project category. It began in October 2015 and the University of Siena is the host institution of the project. The project is focussed upon two Tuscan riverine corridors leading from the Gulf of Follonica in the Tyrrhenian Sea to the Colline Metallifere. It aims to document and analyze the form and timeframe of economic growth in this part of the Mediterranean, which took place between the 7th and the 12thc. Central to this is an understanding of the processes of change in human settlements, in the natural and farming landscapes in relation to the exploitation of resources, and in the implementation of differing political strategies. This volume presents the multi-disciplinary research focussed upon the key site of the project, Vetricella, and its territory. Vetricella is thought to be the site of Valli, a royal property in the Tuscan march. It is the only Early Medieval property to be extensively studied in Italy. Located on Italy’s Tyrrhenian coast, the archaeology and history of this site provide new insights on estate management, metal production and wider Mediterranean relations in the later first millennium. Apart from reports on the archaeology, the finds from excavations and environmental studies, three essays consider the wider European historical and archaeological context of Vetricella. Future monographs will feature studies by members of the project team on aspects of Vetricella, its finds and territory.

Book Description
March 30, 1919, when this Russian immigrant landed in America, no one could have foretold what an impact he would make. His dreams focused on the new field of aviation spearheaded by the Wright brothers about ten years earlier.His vision was to see large airliners full of people, or cargo, or mail traveling great distances in safety and comfort-and beyond that, a vertical flight machine that would lift straight into the air.His ability to follow those dreams in his newly adopted country seemed unattainable until the combined forces of a fellow immigrant and some determined New Englanders caught on to his unheralded abilities in the world of aviation. Unknown stories of what was happening in the Sikorsky business in the mid-to-late 1920s recently came to light when records of that period were discovered in some old file boxes which had been ignored for 50 or more years. This was new information even for the Sikorsky Archives organization in Stratford, Connecticut.Through extensive research, the author has skillfully woven this new information into the well-known stories of Lindbergh's flight, the Frances Grayson debacle, and Igor Sikorsky's many attempts at providing this country with the best fixed wing aircraft possible-and finally the helicopter. Many beautiful photographs previously unpublished are sure to capture the reader's attention.

Book Description
Technology is constantly evolving, and blockchain is taking development to new places, as mobile did a decade ago – and Ethereum is the leading platform for creating this new wave of applications. This book reveals everything you need to create a robust decentralized application (more commonly known as DApp). Unlike other books on the topic, this one focuses on the web application layer, and guides you in creating great experiences on top of the Ethereum blockchain. You’ll review the challenges and differences involved in developing DApps as opposed to traditional web applications. After a brief introduction to blockchain history and Ethereum in particular, you’ll jump directly into building a sample decentralized application, to familiarize yourself with all the moving pieces. This book offers specific chapters on querying and rendering data from the blockchain, reacting to events, interacting with user accounts, sending transactions, managing gas, handling confirmations and reorganizations, and more. You will also find a chapter dedicated to Solidity that will give you the necessary means to understand and even build your own smart contracts. Other important topics covered include building backend servers that act as indexing layers, and managing storage efficiently with solutions like the interplanetary file system, or IPFS. Last but not least, you will find chapters that examine the biggest problems on Ethereum today: onboarding and scalability. These include the state of the art of the available strategies to tackle them, such as meta-transactions, smart accounts, ENS, state channels, sidechains, and more. What You'll Learn Connect to the blockchain from the browser and send transactions from client-sideBuild a web app that provides a read-only interface to a blockchain contract Create a wallet interface for arbitrary fungible tokens, displaying the user’s balance and allowing for simple transfers to other addressesDevelop a web app that stores large blobs of data off-chain, and keeps a reference to it on-chain (e.g. avatars, long text descriptions) Produce a web app that relies on a centralized server for indexing on-chain information to be presented to the user Who This Book Is For Web developers focused on client-side applications, with knowledge of JavaScript and HTML/CSS.
