Provides an introduction to High-Altitude Platform Stations (HAPS) technology and its applications for wireless communications High-altitude platform stations offer a promising new technology that combines the benefits of terrestrial and satellite communication systems for delivering broadband communications to users at a low cost. They are easily deployable and easy to maintain, which is why they offer a good alternative for network operators who need to find ways to get more coverage to satisfy the increasing demand for more capacity. HAPS are usually balloons, airships or unmanned aerial systems (UAS) located in the stratosphere. An enormous interest has grown worldwide to examine their use not only for broadband communications, but also for emergency services, navigation, traffic monitoring, cellular, etc. Key features include: Unique book focusing on emerging HAPS technology and its applications Provides a thorough overview of the technology including HAPS-based communications systems, antennas for HAPS, radio propagation and channel modelling issues and HAPS networking aspects Presents various HAPS-related projects and initiatives developed throughout the world (North America, Europe and Asia-Pacific) Features a comprehensive overview on both aeronautical and telecommunications regulatory aspects, which will affect the deployment and future developments in the field of HAPS High-Altitude Platform Systems for Wireless Communications will prove essential reading for postgraduate students in the field of HAPS, engineers, developers and designers involved in the design and maintenance of HAPS, aerospace engineers, and communications system planners and researchers.

In Kingsley Amis’s virtuoso foray into virtual history it is 1976 but the modern world is a medieval relic, frozen in intellectual and spiritual time ever since Martin Luther was promoted to pope back in the sixteenth century. Stephen the Third, the king of England, has just died, and Mass (Mozart’s second requiem) is about to be sung to lay him to rest. In the choir is our hero, Hubert Anvil, an extremely ordinary ten-year-old boy with a faultless voice. In the audience is a select group of experts whose job is to determine whether that faultless voice should be preserved by performing a certain operation. Art, after all, is worth any sacrifice. How Hubert realizes what lies in store for him and how he deals with the whirlpool of piety, menace, terror, and passion that he soon finds himself in are the subject of a classic piece of counterfactual fiction equal to Philip K. Dick’s The Man in the High Castle. The Alteration won the John W. Campbell Memorial Award for best science-fiction novel in 1976.

Theodore Sider presents a broad new vision of metaphysics centred on the idea of structure. To describe the world well we must use concepts that 'carve at the joints', so that conceptual structure matches reality's structure. This approach illuminates a wide range of topics, such as time, modality, ontology, and the status of metaphysics itself.

Hydroxyapatite in the form of hydroxycarbonate apatite is the principal mineral component of bone tissue in mammals. In Bioceramics, it is classed as a bioactive material, which means bone tissue grows directly on it when placed in apposition without intervening fibrous tissue. Hydroxyapatite is hence commonly used as bone grafts, fillers and as coatings for metal implants. This important book provides an overview of the most recent research and developments involving hydroxyapatite as a key material in medicine and its application. Reviews the important properties of hydroxyapatite as a biomaterial Considers a range of specific forms of the material and their advantages Reviews a range of specific medical applications for this important material
