The Space Shuttle tells the story of NASA's amazing Space Shuttle program and its 140 space flights (135 missions, plus five Approach and Landing Tests) in a uniquely designed and covetable way. The Space Shuttle program's first free flight test was taken on August 12, 1977. Its first official mission was launched on April 12, 1981. Its final mission and flight was taken on July 8, 2011. The program's six orbiter vehicles are Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavour. Each mission has its own fascinating story, and The Space Shuttle retells these stories, in chronological order, through incredible photos taken by NASA photojournalists, fine art photographers, and the astronauts themselves. Each image is accompanied by a short text that includes quick facts such as crew members, launch date, and landing date, as well as a short overview of highlights and purpose. For example, STS-78's mission was to study circadian rhythms in space; STS-41G's mission was to take photographs in-flight, seen in the IMAX movie The Dream Is Alive; and famously, the first untethered space walk, taken by astronaut Bruce McCandless on STS-41B using a self-propelled backpack unit (called a Man Maneuvering Unit [MMU]), allowed astronauts to capture satellites for retrieval and repair and for the planned construction of what became the International Space Station (ISS). Prior to this mission, astronauts were attached to the shuttle with safety lines. The photo of McCandless floating above Earth's surface is one of the most celebrated and famous space photographs ever. These are just a few of the 140 stories Miller tells in this beautiful volume.

Markus G.R. Sause, Elena Jasiuniene
R1,553 Discovery Miles 15 530 Ships in 10 - 15 working days

This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.

This thesis presents a novel ultrasonic instrument for non-invasive and in-situ characterization of journal bearing lubricant viscosity. In particular, the application to journal bearings is described by non-invasively measuring the viscosity and localized power losses throughout operation. This ultrasonic viscometer is based on the reflection of polarized shear waves from a thin resonating coating layer to increase the measurement sensitivity, in comparison to conventional ultrasonic methods. This instrument allows for a full engine oil viscoelastic characterization in-situ. The book investigates the effects of temperature, pressure and shear rate, and describes in detail the ultrasonic setup and method. Further, it demonstrates that the same technique can be applied similarly to monitor the lubrication of other engine components. As such, it offers a unique instrument that can drive the research of oil formulations to improve engine performance and fulfill the requirements of international fuel economy regulations.

R4,239 Discovery Miles 42 390 Ships in 12 - 19 working days

This book focuses on the design of secure and efficient signature and signcryption schemes for vehicular ad-hoc networks (VANETs). We use methods such as public key cryptography (PKI), identity-based cryptography (IDC), and certificateless cryptography (CLC) to design bilinear pairing and elliptic curve cryptography-based signature and signcryption schemes and prove their security in the random oracle model. The signature schemes ensure the authenticity of source and integrity of a safety message. While signcryption schemes ensure authentication and confidentiality of the safety message in a single logical step. To provide readers to study the schemes that securely and efficiently process a message and multiple messages in vehicle to vehicle and vehicle to infrastructure communications is the main benefit of this book. In addition, it can benefit researchers, engineers, and graduate students in the fields of security and privacy of VANETs, Internet of vehicles securty, wireless body area networks security, etc.

Complex System Reliability presents a state-of-the-art treatment of complex multi-channel system reliability assessment and provides the requisite tools, techniques and algorithms required for designing, evaluating and optimizing ultra-reliable redundant systems. Critical topics that make Complex System Reliability a unique and definitive resource include: * redundant system analysis for k-out-of-n systems (including complex systems with embedded k-out-of-n structures) involving both perfect and imperfect fault coverage; * imperfect fault coverage analysis techniques, including algorithms for assessing the reliability of redundant systems in which each element is subject to a given coverage value (element level coverage) or in which the system uses voting to avoid the effects of a failed element (fault level coverage); and * state-of-the-art binary decision diagram analysis techniques, including the latest and most efficient algorithms for the reliability assessment of large, complex redundant systems. This practical presentation includes numerous fully worked examples that provide detailed explanations of both the underlying design principles and the techniques (such as combinatorial, recursive and binary decision diagram algorithms) used to obtain quantitative results. Many of the worked examples are based on the design of modern digital fly-by-wire control system technology. Complex System Reliability provides in-depth coverage of systems subject to either perfect or imperfect fault coverage and also the most recent techniques for correctly assessing the reliability of redundant systems that use mid-value-select voting as their primary means of redundancy management. It is a valuable resource for those involved in the design and reliability assessment of highly reliable systems, particularly in the aerospace and automotive sectors.

The Flight of the Mew Gull (Paperback, New edition): Alex Henshaw The Flight of the Mew Gull (Paperback, New edition)
Alex Henshaw
R564 Discovery Miles 5 640 Ships in 12 - 19 working days

Alex Henshaw had the luck to grow up in the '20s and '30s during the golden age of flying. The Blue Riband of flying in the British Isles between the two World Wars was the King's Cup: Henshaw set his heart on it, developing a technique of racing which extracted the very maximum from his aircraft: firs the Comper Swift and then the DH Leopard Moth. Parallel with his search for speed was an obsession with making accurate landfalls, and he developed this blind-flying taken deliberately in a flying partnership with his father on many carefully planned long-distance survery flights. His exciting apprenticeship in these two skills was crowned by the acquisition of the Percival Mew Gull G-AEXF in 1937. His amazing solo flight to Cape Town and back in February 1939 established several solo records that still stand today, almost 60 years later. This feat of navigation and airmanship must surely be one of man's greatest flights - 12,754 miles over desert, sea and jungle in a single-engined light aircraft.

R5,832 Discovery Miles 58 320 Ships in 10 - 15 working days

Nondestructive Evaluation (NDE) becomes a key discipline for modem technology. Information about materials defects and properties is significant to guarantee reliability of a product and avoid fatal accidents. For instance technologies with high safety requirements like aviation, automotive, and energy production are driving forces for NDE. Keeping in mind that aging of the infrastructure is an issue in all industrial countries and that, for example, an aircraft can have a lifetime of several decades poses new challenges for NDE and especially nondestructive materials characterization. Besides the traditional in field applications, NDE becomes more and more a tool to study materials degradation processes and to provide engineers with input data for sophisticated models describing materials behavior and the life of components. At present, this marriage of NDE and materials modeling shows significant success in predicting damage progression (corrosion, fatigue) and thus an enhancement of availability and reliability of components and complete aircraft. This book will give a snapshot of the present research in materials characterization of aging aircraft. Methods considered are x-ray, ultrasonic, optical and thermal techniques and in particular techniques with high spatial resolution to detect and quantify early stages of degradation or to characterize materials microstructure. Every chapter briefly describes the basics and the principles of one NDE method under consideration. Discussing recent research results by applying these methods completes the chapters. The readers will get an overview of the present state of the art of materials characterization techniques."

A sailing classic, of real life adventure, beautifully illustratedTV Presenter JULIETTE FOSTER: "Captain George P Boughton's maritime career began in 1881 at the age of 12, and thanks to his grandson, the founder of GB Publishing Org, this intriguing memoir of a life at sea is now available to a new generation of readers." THE TIMES LITERARY SUPPLEMENT: "His book is genuine sea salt...warm colours of Mr Shoesmith's pictures accord well with the romantic story [of days before steamships]" THE SPECTATOR: "recalls emotions [on sea-life] that have fleeted from the minds of most" First published in 1926, Seafaring - The Full Story reveals that a life on the ocean waves was anything but jolly: conditions were tough, the food was just about edible while the work was back-breaking - although the salt-of-the-earth camaraderie helped. As much a one-man reminiscence as it is an elegy for a forgotten way of life, it's not hard to imagine a gravely-voiced Boughton recalling the era of the 'large sailing ships'. and why the world stopped being a better place when they were forced off the sea. Boughton died in 1940 at the age of 71, having worked his way up to the position of Superintendent to the Shipping Federation of Britain. With the publication of these memoirs, his contribution to our understanding of this area of history will surely live on." In this edition of Seafaring, which deals with ships and life aboard ships in the days before steam had conquered sail, a Prologue is added that tells of the tragic circumstances that led up to the author going to sea when aged twelve. An Epilogue also reveals his fortunes since writing the book. The men who spent the best part of their lives on sailing vessels are now gone but fortunately Captain Boughton, as one of them, committed to writing his first hand account of what their lives aboard were really like. The salt of the sea is in these breezy pages; they reflect the virile enjoyment with which the men of whom Captain Boughton writes faced the hardships of their existence. ~*~ The inclusion of several of the traditional sea "chanties", with the musical scores, and the end-papers that illustrate sailors' knots, add the final flavour to an inspiring and enduring book.

R3,455 Discovery Miles 34 550 Ships in 12 - 19 working days

High-contrast astronomical imaging has progressed significantly in the past decade. Many of these techniques have been laboratory demonstrated to perform at contrast levels adequate for the detection of Solar System-like planets and dust around nearby stars. None of them, however, have been demonstrated in space. The state of the art in high-contrast imaging systems that have been built for space-based observation, the environment best suited for spectroscopic study of exo-Earths, is the nulling interferometer that was flown on the Planetary Imaging Concept Testbed Using a Rocket Experiment (PICTURE). The PICTURE nulling interferometer, built from multiple optical elements, relies on the incorporation of additional dispersive components in order to deliver the broadband performance preferred for faint object imaging. These elements add to the cost, complexity, and misalignment risk of the instrument.
The Monolithic Achromatic Nulling Interference Coronagraph (MANIC) Brian Hicks describe in this thesis the first optic of its kind. He has taken the multiple optical element concept described in earlier works from theory to a flyable monolithic optic. Brian has advanced the state of the art in nulling interferometers by improving optical stability and robustness. Following application of the fabrication method described in this work, the design of MANIC also allows for broader band performance at higher contrast than that achieved with the PICTURE nulling interferometer.

R4,552 Discovery Miles 45 520 Ships in 10 - 15 working days

Due to the explosive global growth in the number of mobile subscribers, as well as the growth predicted in the mobile data segment, the need for improved spectrum efficiency on the radio interface becomes more and more important. Frequency hopping (FH) is an effective method for improving the spectrum efficiency. One of the advantages of FH is that it can be combined with other spectral efficiency improving features like power control, handover and reuse partitioning. Performance Enhancements in a Frequency Hopping GSM Network covers FH and some of the additional features in detail. It begins with an in-depth description of the basic concept of FH on link level as well as on system level. Different methods have been used for analysis, such as link level simulations, network level simulations and classic tele-traffic theory. Special features of Performance Enhancements in a Frequency Hopping GSM Network Combines the practical experiences of operator and vendor with more theoretical research methods. An in-depth treatment of prevailing problems in GSM networks; Presentation of a new method, computer-aided network design (CAND), which has been developed to analyse the complex network structures of a GSM network. CAND provides the possibility for more realistic performance evaluations than conventional methods; Provides GSM-specific analysis of functionality improvements in power control, discontinuous transmission, and several handover algorithms; Explanation of the quality and capacity gains of features like the combination of FH and reuse partitioning, referred to as intelligent frequency hopping; A frequency planning method for FH GSM networks is presented. This method exploits the benefits from FH directly in the allocation process, increasing the overall frequency plan.
