Noise Resistance Enhancement in Aircraft Navigation and Connected Systems
This book presents methods and algorithms to improve noise immunity of the navigation systems of civil aviation aircraft, operating on the basis of satellite radio navigation systems, as well as improving the quality of the transmission of navigation information by selecting a rational communication resource. The book provides for its productive perception both by specialists involved in the development and operation of radio electronic equipment, responsible for navigation and communication support of civil aviation aircraft, as well as by graduate students or senior students, since this book examines in detail the promising fields of development of these tools taking into account the need to comply with all requirements for noise immunity.
Countering Air Terrorism
This book examines the issues of ensuring anti-terrorist security of an aviation enterprise, provides a history of terrorism in the aviation sector, and analyzes the legal regulations. This book provides mathematical and mathematical–psychological models for reducing the risk of terrorist threats, which makes it possible to objectively increase the safety of air transport facilities, reduce the likelihood of terrorist attacks, save human lives and prevent significant material losses. The solutions of general humanistic problems proposed in the book—preventing accidents and preserving the world—are an original feature of the book, which allows one to treat it with the necessary attentio...
The Medieval South Caucasus
The volume serves as an introduction to what its editors have chosen to call the "artistic cultures" prevalent during the Middle Ages in the region of the South Caucasus. Although far from comprehensive in terms of material, chronology and geography, the volume intends to raise awareness of a region whose artistic wealth and cultural diversity has remained relatively unknown to most medievalists. Stretching from Eastern Anatolia and the Black Sea in the West to the Caspian Sea in the East, and from the snow-capped Great Caucasus mountain range in the north to the Armenian highlands in the south, medieval southern Caucasia was originally divided into the kingdom of Caucasian Albania, Greater ...
Airbreathing Propulsion
Airbreathing Propulsion covers the physics of combustion, fluid and thermo-dynamics, and structural mechanics of airbreathing engines, including piston, turboprop, turbojet, turbofan, and ramjet engines. End-of-chapter exercises allow the reader to practice the fundamental concepts behind airbreathing propulsion, and the included PAGIC computer code will help the reader to examine the relationships between the performance parameters of different engines. Large amounts of data have on many different piston, turbojet, and turboprop engines have been compiled for this book and are included as an appendix. This textbook is ideal for senior undergraduate and graduate students studying aeronautical engineering, aerospace engineering, and mechanical engineering.
Vigilant Powers
This book opens to the reader the world of early medieval Armenia: its sacred landscapes, striking churches, and rich literary and religious traditions. Examination of three sculpted and inscribed monuments, produced during the global wars of the seventh century, demonstrates the close engagement of Armenia with Byzantine imperial interests and with contemporary events in the Holy Land. The dramatic context of the military frontier, and the apocalyptic expectations of its contemporaries, shaped a vibrant visual culture with ties to both the Byzantine and Sasanian worlds. The seventh-century monuments of Armenia are important not just as an extraordinary moment of local cultural production; they fill a crucial gap in our knowledge about the medieval traditions of the Christian East at a time from which little survives from Constantinople and the imperial heartland. East of Rome, North of Jerusalem is the first English-language book devoted to the subject.
Chosen Places: Constructing New Jerusalems in Slavia Orthodoxa
In Chosen Places. Constructing New Jerusalems in Slavia Orthodoxa, Jelena Erdeljan focuses on the Old Testament topic of the divinely-chosen status of Jerusalem and translatio Hierosolymi, including the history, process and media of formulating and disseminating this idea and its spatial-visual matrix in Christian visual culture. Firstly the study presents the case of Constantinople, the capital of the Byzantine Empire, as New Jerusalem, and secondly, in relation to Constatinople, discussion focuses on the cases of the capitals of Slavia Orthodoxa in the later Middle Ages: Turnovo, Belgrade and Moscow. The idea of Jerusalem corresponds with the idea of a mystical center, the center of the historical Christian world, which travels and follows the path of eschatologial realisation.
Flexible Spacecraft Dynamics, Control and Guidance
This book is an up-to-date compendium on spacecraft attitude and orbit control (AOC) that offers a systematic and complete treatment of the subject with the aim of imparting the theoretical and practical knowledge that is required by designers, engineers, and researchers. After an introduction on the kinematics of the flexible and agile space vehicles, the modern architecture and functions of an AOC system are described and the main AOC modes reviewed with possible design solutions and examples. The dynamics of the flexible body in space are then considered using an original Lagrangian approach suitable for the control applications of large space flexible structures. Subsequent chapters address optimal control theory, attitude control methods, and orbit control applications, including the optimal orbital transfer with finite and infinite thrust. The theory is integrated with a description of current propulsion systems, with the focus especially on the new electric propulsion systems and state of the art sensors and actuators.
Stability and Control of Conventional and Unconventional Aerospace Vehicle Configurations
This book introduces a stability and control methodology named AeroMech, capable of sizing the primary control effectors of fixed wing subsonic to hypersonic designs of conventional and unconventional configuration layout. Control power demands are harmonized with static-, dynamic-, and maneuver stability requirements, while taking the six-degree-of-freedom trim state into account. The stability and control analysis solves the static- and dynamic equations of motion combined with non-linear vortex lattice aerodynamics for analysis. The true complexity of addressing subsonic to hypersonic vehicle stability and control during the conceptual design phase is hidden in the objective to develop a ...
Array Beamforming with Linear Difference Equations
This book studies the link between differential beamforming and differential equations which in turn enables the study of fundamental theory and methods of beamforming from a different perspective, leading to new insights into the problem and new methods to solve the problem. The book first presents a brief overview of the problems and methods for beamforming and some performance measures popularly used either to evaluate beamformers or to derive optimal beamformers. Then, first-order, second-order, and general high-order linear difference equations are discussed, based on which the authors show how to formulate the beamforming problem and derive different beamforming methods, including fixe...
Air Traffic Control Automated Systems
This book highlights operation principles for Air Traffic Control Automated Systems (ATCAS), new scientific directions in design and application of dispatching training simulators and parameters of ATCAS radio equipment items for aircraft positioning. This book is designed for specialists in air traffic control and navigation at a professional and scientific level. The following topics are also included in this book: personnel actions in emergency, including such unforeseen circumstances as communication failure, airplane wandering off course, unrecognized aircraft appearance in the air traffic service zone, aerial target interception, fuel draining, airborne collision avoidance system (ACAS) alarm, emergency stacking and volcanic ash cloud straight ahead.
