Book Description
This book examines signal processing techniques for cognitive radios. The book is divided into three parts: Part I, is an introduction to cognitive radios and presents a history of the cognitive radio (CR), and introduce their architecture, functionalities, ideal aspects, hardware platforms, and state-of-the-art developments. Dr. Jayaweera also introduces the specific type of CR that has gained the most research attention in recent years: the CR for Dynamic Spectrum Access (DSA). Part II of the book, Theoretical Foundations, guides the reader from classical to modern theories on statistical signal processing and inference. The author addresses detection and estimation theory, power spectrum estimation, classification, adaptive algorithms (machine learning), and inference and decision processes. Applications to the signal processing, inference and learning problems encountered in cognitive radios are interspersed throughout with concrete and accessible examples. Part III of the book, Signal Processing in Radios, identifies the key signal processing, inference, and learning tasks to be performed by wideband autonomous cognitive radios. The author provides signal processing solutions to each task by relating the tasks to materials covered in Part II. Specialized chapters then discuss specific signal processing algorithms required for DSA and DSS cognitive radios.

Book Description
What has happened to George Adamski since he wrote the famous incidents in Flying Saucers Have Landed? Since the memorable November 20, 1952, when he first made personal contact with a man from another world? Since December 13, 1952 when he was able to make photographs within 100 feet of the same saucer that had brought his original visitor? Inside The Space Ships is Adamski’s own story of what has happened to him since then. It begins with his first meeting, a few months later, with a second man from another world—his first meeting with one who speaks to him. This second visitor brings him to a Venusian Scout (flying saucer) and this, in turn, brings him to a mother ship. Later lie is conveyed in both a Saturnian Scout and a Saturnian mother ship. Adamski tells us what transpires in these space craft and what the men and women from other worlds have told him. Adamski’s photographs of flying saucers, originally published in Flying Saucers Have Landed, have since become world-famous as other witnesses in other parts of the world have succeeded in taking photographs identical with his. Now, however, in Inside The Space Ships, Adamski gives us 16 photographs and illustrations, no longer of Scouts (flying saucers) mostly, but of the great space ships from which they are launched. The main group of these photographs was taken in April, 1955, and neither the photographs nor a description of them has ever been published before.

Book Description
The academic course of Machine Design Elements and Assemblies (a.k.a. "Machine Design," "Mechanical Engineering Design," etc.) is based on the fundamentals of several different core disciplines, and should prepare students to meet challenges associated with solving real-life mechanical engineering design problems commonly found in industry. Other works focus primarily on verifying calculations of existing machine elements in isolation, while this textbook goes beyond and includes the design calculations necessary for determining the specifications of elements for new assemblies, and accounting for the interaction between them. Machine Design Elements and Assemblies addresses the design considerations associated with the functionality of a full assembly. Most chapters end with a design project that gets progressively more complex. Numerous reviews of prerequisite materials are purposely not included in this title, resulting in a more concise, more practical, and far less expensive product for students, engineers, and professors. Rounding out this incredible package are 120 problems and answers that can be assigned as homework. And nearly 400 additional problems are available on the book's affiliated website, www.machinedesignea.com.

Book Description
Today's strategic environment is dynamic and rapidly changing. Warfighting domains, including air, land, and sea, where the United States has dominated for almost one half-century, are increasingly being tested by traditional states, as well as non-state actors. Globalization has facilitated the ability of less capable nations to garner critical warfighting technology. The parity in technology between nations at war is no longer as great. This leveled the playing field and allowed for non-state actors to have dramatic influence on powerful nations, which has not been the case in the past. Fiscal limitations, unsustainable operations tempos, inadequate training, and current operational planning paradigms and processes have put the United States Military in a perilous situation and hindered its ability to conduct effective and efficient defense. The greatest calamity that could arise from these realities is the inability to address XDS in full-spectrum combat operations against a near-peer adversary.

Book Description
If Adamski and the six companions who swore an affidavit to his Space Man encounter are not trying to pull off a gigantic hoax, then this is quite possibly the greatest story ever." That was what the Daily Sketch wrote about" Flying Saucers Have Landed." For, in the second part of this book, Adamski swears that he saw a space ship land in the desert in California and that he made contact with one of its occupants. More, he provides considerable testimony to support his claims. Desmond Leslie, who contributes the first part of the book, goes even further, asserting that flying saucers have been landing on earth for thousands of years, and gives records of their arrivals
