State of the art resource covering key technologies and related theories of inter-satellite links Inter-Satellite Links Technology explores satellite networking as a growing topic in the field of communication technology, introducing the definition, types, and working frequency bands of inter-satellite links, discussing the number of orbital elements of the spacecraft motion state under two-body motion and their conversion relationship, and establishing the basic demand model for inter-satellite link network, chain topology model, and transmission protocol model. The book focuses on the analysis and introduction of the principles and error sources of microwave and laser inter-satellite ranging, including the basic composition, workflow, and constraints of the laser inter-satellite link, and related design principles of the inter-satellite laser transmitter and receivers. Later chapters also discuss theories and methods of acquisition, alignment, and tracking, the impact of alignment errors on performance, and inter-satellite link modulation and its implementation. Specific sample topics covered in Inter-Satellite Links Technology include: Pulse position modulation (PPM), Differential Pulse Position Modulation (DPPM), Digital Pulse Interval Modulation (DPIM), and Double-head pulse interval modulation (DH-PIM) Basic demand model of inter-satellite link network application, including basic configuration of constellations and inter-satellite transmission networks Inter-satellite ranging accuracy, principles of microwave inter-satellite ranging, and analysis of microwave ranging error sources Effect of tracking error on the beam distribution at the receiving end and influence of tracking and pointing error on communication error rate Inter-Satellite Links Technology serves a completely comprehensive resource on the subject and is a must-have reference for experts and scholars in aerospace, along with graduates and senior undergraduates in related programs of study.

In many applications, radio frequency (RF) signals need to be transmitted and processed without being digitalized. Optical fiber provides a transmission medium in which RF modulated optical carriers can be transmitted and distributed with very low loss, making it more efficient and less costly than conventional electronic systems. This volume presents a review of RF photonic components, transmission systems, and signal processing examples in optical fibers from leading academic, government, and industry scientists working in this field. It also introduces the reader to various related technologies such as direct modulation of laser sources, external modulation techniques, and detectors. The text is aimed at engineers and scientists engaged in the research and development of optical fibers and analog RF applications. With an emphasis on design, performance and practical application, this book will be of particular interest to those developing systems based on this technology.

For more than a century, scientists have raced to unravel the human family tree and have grappled with its complications. Now, with an astonishing new discovery, everything we thought we knew about primate origins could change. Lying inside a high-security vault, deep within the heart of one of the world's leading natural history museums, is the scientific find of a lifetime - a perfectly fossilized early primate, older than the previously most famous primate fossil, Lucy, by forty-four million years. A secret until now, the fossil - "Ida" to theresearchers who have painstakingly verified her provenance - is the most complete primate fossil ever found. Forty-seven million years old, Ida rewrites what we've assumed about the earliest primate origins. Her completeness is unparalleled - so much of what we understand about evolution comes from partial fossils and even single bones, but Ida's fossilization offers much more than that, from a haunting "skin shadow" to her stomach contents. And, remarkably, knowledge of her discovery and existence almost never saw the light of day. With exclusive access to the first scientiststo study her, the award-winning science writer Colin Tudge tells the history of Ida and her place in the world. A magnificent, cutting-edge scientific detective story followed her discovery, and The Link offers a wide-ranging investigation into Ida and our earliest origins. At the same time, it opens a stunningly evocative window into our past and changes what we know about primate evolution and, ultimately, our own.

A masterpiece of architectural literature, "The Links" is the first book that fully addresses the complexities of the golf course in terms of design, construction, and definition of the game. Written in 1926, Robert Hunter conceptualized "The Links" as a complete study, a manual for golf course architects and design enthusiasts, specifically written to advance the field of study in a way that had never been tried before. Although Hunter was not a golf course architect by trade, or even a golfing professional, his background as a dedicated socialist reformer led to his unique understanding of the relationship between golf and its greater contribution to society. The challenges posed by golf, as well as the beauty produced by the singular nature of the world’s most famous links, led Hunter to conclude that diversity is what makes golf the cherished game that it is. In "The Links," he postulates, “It is not the love of something easy which has drawn men like a magnet for hundreds of years to this royal and ancient pastime; on the contrary, it is the maddening difficulty of it.” Supported by over fifty photographs and original drawings, "The Links" details the essential features of an ideal golf course and provides insight into the strategies and methods used to design the world’s most renowned courses. As acclaimed architect Dr. Alister MacKenzie wrote, “I have read "The Links" with the greatest interest. Mr. Hunter is familiar with all the great courses in the world and he has written a most entertaining book, which I am sure every golfer will read with profit. I do not hesitate to say that it is the classic of the subject.”

From the internationally acclaimed author of North of Dawn, Links is a novel that will stand as a classic of modern world literature. Jeebleh is returning to Mogadiscio, Somalia, for the first time in twenty years. But this is not a nostalgia trip—his last residence there was a jail cell. And who could feel nostalgic for a city like this? U.S. troops have come and gone, and the decimated city is ruled by clan warlords and patrolled by qaat-chewing gangs who shoot civilians to relieve their adolescent boredom. Diverted in his pilgrimage to visit his mother’s grave, Jeebleh is asked to investigate the abduction of the young daughter of one of his closest friend’s family. But he learns quickly that any act in this city, particularly an act of justice, is much more complicated than he might have imagined.

How can our societies be stabilized in a crisis? Why can we enjoy and understand Shakespeare? Why are fruitflies uniform? How do omnivorous eating habits aid our survival? What makes the Mona Lisa’s smile beautiful? How do women keep our social structures intact? – Could there possibly be a single answer to all these questions? This book shows that the statement: "weak links stabilize complex systems" provides the key to understanding each of these intriguing puzzles, and many more besides. The author, a recipient of several distinguished science communication prizes, explains weak or low probability interactions, and uses them as connecting threads in a vast variety of networks from proteins to ecosystems. This unique book and the ideas it develops will have a significant impact on diverse, seemingly unrelated fields of study.
