El carbono es un elemento fascinante, capaz de dar lugar a muy diversos e increíbles materiales. Se conocen cerca de 16 millones de compuestos de carbono y forma parte de todos los seres vivos conocidos. La organizacion del carbono en capas bidimensionales unidas debilmente entre si da lugar al grafito, que es un material blando, opaco y negro, y a su vez es conductor de la electricidad. Cuando se empaquetan densamente en una estructura tridimensional, los atomos de carbono dan lugar al diamante, que es transparente en incoloro, el material mas duro que se conoce y que ademas es un aislante perfecto. En la actualidad, el grafeno, formado por anillos de solo seis atomos de carbono, esta suponiendo una autentica revolucion cientifica y mediatica.Este libro es un viaje a traves de las distintas formas alotropicas del carbono que existen, y que han dado lugar al desarrollo de nuevos materiales con miles de aplicaciones en multitud de sectores industriales.

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 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.

Active Control of Aircraft Cabin Noise provides a bridge to fill the gap between robust control theory and practical applications of active noise control systems in aircraft cabin.Both the possibilities and limitations of structural solutions to enhance aircraft cabin comfort by reducing interior noise are discussed supported by a wide range of topics in engineering, from finite element modeling to multichannel adaptive feed-forward control, usually dealt separately in the literature. In addition, experimental noise attenuation results with passengers'' subjective perceptions predicting the effects of cabin noise on comfort assessments is examined. Theoretical and experimental research is detailed enough to capture the interest of the non-expert in engineering who wishes to have an overview of some of the active noise control applications in aircraft.This book may be used as an advanced textbook by graduate and undergraduate students in aeronautical engineering, and would be an authoritative resource book for research into the subject.

There has been a great deal of excitement in the last ten years over the emer gence of new mathematical techniques for the analysis and control of nonlinear systems: Witness the emergence of a set of simplified tools for the analysis of bifurcations, chaos, and other complicated dynamical behavior and the develop ment of a comprehensive theory of geometric nonlinear control.Coupled with this set of analytic advances has been the vast increase in computational power available for both the simulation and visualization of nonlinear systems as well as for the implementation in real time of sophisticated, real-time nonlinear control laws. Thus, technological advances havebolstered the impact of analytic advances and produced a tremendous variety of new problems and applications that are nonlinear in an essential way.Nonlinear controllaws have been implemented for sophisticated flight control systems on board helicopters, and vertical take offand landing aircraft; adaptive, nonlinearcontrollaws havebeen implementedfor robot manipulators operating either singly, or in cooperation on a multi-fingered robot hand; adaptive control laws have been implemented forjetengines andautomotive fuel injection systems, as well as for automated highway systems and air traffic management systems, to mention a few examples.Bifurcation theory has been used to explain and understand the onset of fiutterin the dynamics of aircraft wing structures, the onset of oscillations in nonlinear circuits, surge and stall in aircraft engines, voltage collapse in a power transmission network.

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.
