Digital Transmission Systems

Digital Transmission Systems

In the development of telecommunication networks throughout the world, digital transmission has now replaced analog transmission as the predominant choice for new transmission facilities. This trend began in the early 1960s when the American Telephone and Telegraph Company first introduced pulse code modulation as a means of increasing capacity in their cable plant. Since that time, digital transmission applications have grown dramatically, notably in the United States, Canada, Japan, and Western Europe. With the rapidity of digital transmission developments and imple­ mentation, however, there has been a surprising lack of textbooks written on the subject. This book grew out of my work, research, and teaching in digital transmission systems. My objective is to provide an overview of the subject. To accomplish this end, theory has been blended with practice in order to illustrate how one applies theoretical principles to actual design and imple­ mentation. The book has abundant design examples and references to actual systems. These examples have been drawn from common carriers, manufac­ turers, and my own experience. Considerable effort has been made to include up-to-date standards, such as those published by the CCITT and CCIR, and to interpret their recommendations in the context of present-day digital transmission systems.
Winery Utilities

Winery Utilities

This book has been written for an eclectic audience of winery developers (owners), winemakers with utility responsibilities (real or implied), winery design professionals (architects and engineers), and university-level enol­ ogy professors, all of whom at sometime in their careers must address the subject of winery site utilities as a distinct and important element of their jobs. Wine and other fermented beverages in one form or another are pro­ duced commercially in almost all temperate zones of the world. Utility requirements for wineries, which use grapes as the fermentable sugar source, are the focus of this reference book, although similarities in fun­ damental production processes for other subdivisions of the fermented beverage industry may find useful reference information in the chapters which follow. Wine production methods may differ somewhat from country to coun­ try, but the sizing, need for reliability, ease of operation, and cost-effec­ tiveness of water, wastewater, electrical, fire protection, and other support systems remain nearly universally constant. Of necessity, the author's past planning and design experience with nearly 60 winery utility systems, will xi xii Preface emphasize contemporary design fundamentals related to the U.S. wine industry. However, where possible, opportunities will be taken to relate American practice to, for example, European, Australian, and South Amer­ ican wine industries where discrete differences in utility systems have been observed by the author or discovered in the literature research that was part of the production effort for this volume.
The Politics of Disease

The Politics of Disease

Even a pandemic is subject to politics. Disease has always been a catalyst for change, influencing wars, the rise and fall of leaders, economics, religion, art, and, most certainly, people's lives. Disease, as Covid demonstrates, can be politicized as well. While the pandemic that erupted in 2019 may be the most politicized in American history, it is far from the only one. Indeed, disease has afflicted the United States since the beginning, and it has been exploited by politicians, the media, and others to further their agendas. Parties have defined disease, and disease has defined political parties. From the 16th century to the present, this work traces the interactions of disease and politics in the United States. Major pandemics, local outbreaks, and even presidential illnesses are all examined to see how political parties have seized upon their origins, spread, and treatment to promote their own ideologies. Immigration, civil rights, gender, war, economics, public health, modernization, and elections are all discussed in relation to the outbreaks. The book demonstrates how disease helped secure independence, led to the writing of the Constitution, brought America into the War of 1812 and the Spanish-American War, led to limits on immigration, kept the United States out of the League of Nations, led to women voting, produced two political parties--and more.
Star Trek: The Original Series: Allegiance in Exile
A beautiful green world, rich in fertile soil and temperate climate . . . a textbook Class-M planet that should be teeming with life. Scans show no life-signs, but there are refined metals, including those associated with a space-faring race . . . and a lone city. But where are all of the inhabitants? Captain James T. Kirk leads a landing party from the U.S.S. Enterprise, hoping to get some answers. The away team discovers a city in ruins, covered by dust, utterly bereft of life. Tricorder readings indicate that this is no ancient metropolis-it has been deserted only for a year. And just beyond the citadel lies what appears to be an ancient spaceport . . . a graveyard of ships that have clearly been sabotaged. With these ruins too far from either the Klingon or the Romulan Empires, the Enterprisecrew can only wonder: Who could have done this? And could this unnamed threat now pose an imminent danger to the Federation?
Typhon Pact #3: Rough Beasts of Empire
The next novel in the Typhon Pact adventure in the universe of Star Trek: The Next Generation. Still on Romulus in pursuit of his goal of reunifying the Vulcans and Romulans, Spock finds himself in the middle of a massive power struggle. In the wake of the assassination of the Praetor and the Senate, the Romulans have cleaved in two. While Empress Donatra has led her nascent Imperial Romulan State to establish relations with the Federation, Praetor Tal'aura has guided the original Romulan Star Empire toward joining the newly formed Typhon Pact. But numerous factions within the two Romulan nations vie for power and undivided leadership, and Machiavellian plots unfold as forces within and without the empires conduct high-stakes political maneuvers. Meanwhile, four years after Benjamin Sisko returned from the Celestial Temple, circumstances have changed, his hopes for a peaceful life on Bajor with his wife and daughter beginning to slip away. After temporarily rejoining Starfleet for an all-hands-on-deck battle against the Borg, he must consider an offer to have him return for a longer stint. Beset by troubling events, he seeks spiritual guidance, facing demons new and old, including difficult memories from his time in the last Federation-Tzenkethi war.

Conventional wisdom holds that the Internet makes the world flat and reduces friction by erasing the impact of the physical world on our buying habits. But Wharton professor and marketing expert David R. Bell argues that the way we use the Internet is still largely shaped by the physical world we inhabit. Anyone can go online and buy a pair of jeans—but the likelihood that we will do so depends to a significant degree on where we live. The presence of stores nearby, trendy and friendly neighbors, and local sales taxes, among other factors, play a critical role in our decision making when it comes to buying online. Our willingness to search for and consume information also depends on where we live and whom we live next to. In Location Is (Still) Everything, Bell offers a fascinating, in-depth look at online commerce and retailing through his years of research, investing, and advising experience. His unique GRAVITY framework is a powerful and practical tool that uses fundamental human behaviors and location-based conditions to explain how the real and virtual worlds intersect — and what Internet sellers must do in order to succeed. Entrepreneurs, managers, students, and investors will all benefit from understanding how and why we use the Internet to search, shop, and sell.
