This book focuses on high-gain antennas in the terahertz spectrum and their optimization. The terahertz spectrum is an unallocated EM spectrum, which is being explored for a number of applications, especially to meet increasing demands of high data rates for wireless space communications. Space communication systems using the terahertz spectrum can resolve the problems of limited bandwidth of present wireless communications without radio-frequency interference. This book describes design of such high-gain antennas and their performance enhancement using photonic band gap (PBG) substrates. Further, optimization of antenna models using evolutionary algorithm based computational engine has been included. The optimized high-performance compact antenna may be used for various wireless applications, such as inter-orbital communications and on-vehicle satellite communications.

Alloys are materials having metallic properties and are composed of two or more elements, at least one of which is a metal. In the case of aluminum alloys, most of them contain 90 to 96% aluminum. Aluminum alloys are divided into two categories, wrought alloys and cast alloys. Aluminum casting alloys are used in a large number of applications including automobiles, trucks, transmission of electricity, development of transportation infrastructures, and in the aerospace and other industries.Over the years, aluminum-copper (Al-Cu) cast alloys have been increasingly investigated, the reason being that copper has a significant impact on the strength and hardness of aluminum castings at both ambient and elevated service temperatures. Due to the presence of copper, the mechanical properties of these alloys may be improved via age hardening through the formation of Al2Cu precipitates following aging treatment. This book will first introduce and summarize all about the Al-Cu, LPDC and types of casting, for the objectives, results and conclusions of this study, you need to follow the author's coming publications.

This volume illustrates and documents the instrument panels of six famous German World War II aircraft.

This analysis provides the architecture for a common strategic and analytical thread that can serve as a template for the entire community, as well as for regulators and policymakers who must balance the needs and demands of UAS users with the general publics right to safe skies and privacy. An in-depth analysis of this scope and magnitude requires a thorough examination of the available technology; a comprehensive examination of all of the relevant policy and legal barriers; a look forward to where the technology is heading in the next 25-50 years; and a broad based perspective on what is currently feasible as envisioned by leaders in the field. An understanding of the market forces and business cases that are fuelling the development of the technology is also covered in a focus on the economics of the industry.UAS Integration into Civil Airspace: Policy, Regulations and Strategy presents a strategy for airspace access and integration that will facilitate humanitarian, environmental, social and security uses of unmanned aircraft systems on a global scale, and will furthermore provide a common ground for discussion across international borders, from the local, rulemaking level to overarching diplomatic challenges.

This book presented a suitability model produced to solve what is referred to as the " High Frequency Location Problem" and them tested the results using location allocation concept. A suitability model was built using GIS that took land features along with other data inputs to help narrow down potential building sites for new radio communication tower by considering various variables. After the model identified appropriate sites for building a tower, additional location allocation methods were employed which further reduced the potential tower construction sites to the most optimal location.

This book explores the central problems underlying the insurance of aviation war and terrorism risks and associated perils. It critically analyses the reasons why conventional insurance markets are unwilling or unable to provide sustainable insurance coverage for aviation war and terrorism risks in the aftermath of catastrophic events such as the terrorist events of September 11, 2001. It also examines some of the prominent concepts proposed and/or implemented after 9/11 to determine whether and to what extent these concepts avoid identified pitfalls. Like many of lifes essentials, the importance of insurance is most evident when it is not available. The sheer scale and magnitude of the insurance losses that followed 9/11 caused conventional insurance markets (which hitherto had been offering generous insurance coverage for aviation war and terrorism risks to air transport operators for little or no premium) to withdraw coverage forthwith. The ensuing absence or insufficiency of commercial insurance coverage for aviation war and terrorism risks has sparked a global search for viable and sustainable alternatives. Ten years have since elapsed, and despite numerous efforts, the fundamental problems remain unresolved. The book proceeds on the premise that the underlying issues are not entirely legal in nature; they have immense economic, psychological and policy implications that cannot be underestimated. A multidisciplinary approach is therefore used in examining the issues, drawing heavily upon analytical principles adapted from law and economics and behavioural law and economics. It is hoped that the resulting study will be beneficial not only to lawyers and those interested in aviation insurance but also to economists, air transport insurance program managers, capital market investors and governmental policymakers, both at the national and international levels.

Ensuring a proper operation of the engines over their lifetime is an important air safety aspect. Even though the recent engines are highly reliable the number of accidents due to an incorrect crew response following an Engine malfunction has remained constant for many years. This prompted this study and it reveals that flight crews are not always able to identify and understand engine malfunctions precisely which leads to needless engine shutdowns, incidents and accidents. The scope of this Book is to provide basic guidelines to identify Engine failures/malfunctions and to give operational recommendations in case of Engine malfunction. It can be accomplished using SOM maps by Clustering the various engine parameters based on the parametric variations influenced by the faults,SOM maps are generated and they are stored as the failure template. In addition to their traditional tool based quantitative inspection of some measured variables to detect any deviation from the normal behavior making it possible to anticipate possible faults. By proper detection of the faults suitable malfunction response will be displayed to the crew for their assistance enhancing reliability and safety.

Until recently, the Transportation Security Administration (TSA) had applied relatively uniform methods to screen airline passengers, focusing primarily on advances in screening technology to improve security and efficiency.TSA has recently shifted away from this approach, which assumes a uniform level of risk among all airline travelers, to one that focuses more intently on passengers thought to pose elevated security risks. Risk-based passenger screening includes a number of initiatives that fit within a broader framework addressing security risks, but specifically emphasizes the detection and management of potential threats posed by passengers.This book examines changes to the Secure Flight program since 2009; TSAs efforts to ensure that Secure Flights screening determinations for passengers are implemented at airport checkpoints; and the extent to which program performance measures assess progress toward goals.
