Международные валютно-кредитные и финансовые отношения

Международные валютно-кредитные и фи нансовые отношения составная часть и одна из наиболее сложных сфер рыночного хозяй ства. В них фокусируются проблемы нацио иальной и мировой экономики, развитие кото рых исторически идет параллельно и тесно пе реплетаясь. По мере интернационализации хо зяйственных связей увеличиваются междуна родные потоки товаров, услуг и особенно капи талов и кредитов. Большое влияние на международные ва лютно-кредитные и финансовые отношения оказывают ведущие промышленно развитые страны (особенно «семерка»), которые выступа ют как партнеры-соперники. Последние десяти летия отмечены активизацией развивающихся стран в этой сфере.

Деньги, кредит, банки

Деньги, кредит, банки являются неотъемлемыми атрибутами совре-менной цивилизации. Их функционирование позволяет соединить в непрерывный процесс производство, распределение, обмен и потребле-ние общественного продукта. Без их использования не обходится ни один хозяйствующий субъект. Каждый человек так или иначе постоян-но или эпизодически обращается к банковским услугам. Банки, собирая временно неиспользуемые денежные средства, перераспределяют их между регионами и отраслями, между предприятиями и населением, питают экономику дополнительными капиталами и «энергетическими» ресурсами, создавая базу для приумножения богатства общества.

Essentials of Radio Wave Propagation

If you need to maximize efficiency in wireless network planning, this quick reference guide to an increasingly complex and difficult topic is for you. Using real-world case studies, practical problems and minimum mathematics, the author explains simply and clearly how to predict signal strengths in a variety of situations. More sophisticated methods, which form the basis of software tools for both network planning and spectrum management, are also described. This will be an invaluable resource for network planners, hardware designers, spectrum managers, senior technical managers and policy makers.

Schaum’s Outline of Electronic Communication

This book is intended to be used as a supplement to any textbook covering Electronic Communications. The prerequisites for using this book include basic courses in DC and AC theory as well as a complete course covering the theory and operation of electronic devices. This book will prove extremely helpful for students enrolled in an Electronic Communications course in a two-year technical college, and it should also be quite helpful for students in a four-year electronic engineering program. The book is divided into six chapters which are: Characteristics of Tuned LC Circuits; RF Oscillators, PLLs, and Frequency Synthesizers; Amplitude Modulation; Frequency Modulation; Transmission Lines; and Antennas. It is assumed that the student will use an electronic communications textbook for in-depth discussions of each of the major topics covered. The main purpose of this book is to develop effective problem-solving skills and to help the student study quickly and effectively. The book includes several examples and solved problems which provide the complete worked-out solution to a given problem. At the end of each chapter, there are also several supplementary problems for students to work out on their own.

Handbook on Satellite Communications (HSC)

An essential overview of satellite communications from the organization that sets the international standards. Since their introduction in the mid-1960s, satellite communications have grown from a futuristic experiment into an integral part of today's "wired world." Satellite communications are at the core of a global, automatically switched telephony network. Assembled by the International Telecommunication Union--the international organization that sets the standards for this rapidly growing industry--the Handbook on Satellite Communications, Third Edition brings together basic facts about satellite communications as related to the fixed-satellite service (FSS). It covers the main principles, technologies, and operation of equipment in a tutorial form.

Signals and Systems. A Primer with MATLAB

Signals and Systems: A Primer with MATLAB® provides clear, interesting, and easy-to-understand coverage of continuous-time and discrete-time signals and systems. Each chapter opens with a historical profile or career talk, followed by an introduction that states the chapter objectives and links the chapter to the previous ones. All principles are presented in a lucid, logical, step-by-step approach. As much as possible, the authors avoid wordiness and detail overload that could hide concepts and impede understanding. In recognition of the requirements by the Accreditation Board for Engineering and Technology (ABET) on integrating computer tools, the use of MATLAB® is encouraged in a student-friendly manner. MATLAB is introduced in Appendix B and applied gradually throughout the book. Each illustrative example is immediately followed by a practice problem along with its answer. Students can follow the example step by step to solve the practice problem without flipping pages or looking at the end of the book for answers. These practice problems test students’ comprehension and reinforce key concepts before moving on to the next section.

Essentials of Digital Signal Processing

This textbook offers a fresh approach to digital signal processing (DSP) that combines heuristic reasoning and physical appreciation with sound mathematical methods to illuminate DSP concepts and practices. It uses metaphors, analogies and creative explanations, along with examples and exercises to provide deep and intuitive insights into DSP concepts. Practical DSP requires hybrid systems including both discrete- and continuous-time components. This book follows a holistic approach and presents discrete-time processing as a seamless continuation of continuous-time signals and systems, beginning with a review of continuous-time signals and systems, frequency response, and filtering. The synergistic combination of continuous-time and discrete-time perspectives leads to a deeper appreciation and understanding of DSP concepts and practices. • For upper-level undergraduates • Illustrates concepts with 500 high-quality figures, more than 170 fully worked examples, and hundreds of end-of-chapter problems, more than 150 drill exercises, including complete and detailed solutions • Seamlessly integrates MATLAB throughout the text to enhance learning

Commercial Space Technologies and Applications. Communication, Remote Sensing, GPS, and Meteorological Satellites

This new edition introduces and examines the space technologies that benefit our everyday lives. Each chapter now includes exercises and problems, and the content covers new satellites and emerging technologies. It explores the ever-improving quality of satellite systems and services, and also investigates ways to bring about higher resolution satellite imagery and lower satellite costs. The focus is on man-made satellites, which are becoming smaller, smarter, cheaper, and easier to launch, having a longer life span, and are less susceptible to interference. Furthermore, the book considers advances in several key technologies that affect the satellite industry.

UAV Swarm Networks. Models, Protocols, and Systems

Unmanned aerial vehicles (UAVs) have been used in many important applications. For instance, they can be used to monitor city events by using equipped cameras, where each UAV monitors a certain area of the city. Amazon plans to use UAVs to deliver goods to customers' homes. UAVs can fly in harsh environments (such as the North/South Poles) to collect information about the weather conditions, to understand the Earth's evolution. Military departments can deploy UAVs to collect battlefield information and save soldiers. Although a single UAV could achieve certain tasks, such as delivering goods, many applications require the cooperation of multiple UAVs, which form a UAV network. For example, each UAV only covers a small range in a large city, and multiple UAVs share the complementary image information to obtain the complete picture. Many UAVs can form a swarm to perform challenging tasks, such as forming a specific network shape to attack enemies. In disaster recovery scenes, multiple UAVs fly to different places to detect/save people and coordinate schedule/coverage allocations.
