Book excerpt: Mass Contacts is an astounding story that says that Contact has begun from one who knows. A detailed report of contacts with human type aliens on the Adriatic coast, which answers many of our questions, this book is a milestone for ufologists wh study Contact. They were here and many look like us! It's time for disclosure. Paola Leopizzi Harris-Researcher and Author: Connecting the Dots; Making Sense of UFO Phenomena; Exopolitics: How Does One Speak to a Ball of Light? This book is a true milestone in the spreading of the reality of contacts between our humanity and extraterrestrials, both in the past and now; it gives rise to vital importants, hints in order to understand the epoch-making events that are waiting for us, and inteat with them in the best way. Tom Bosco-NEXUS Magazine-Edizione Italiana Eng. Stefani Breccia and I are friends, and have been responsible keepers of truths that not always were sharable with other people. Both of us have dedicated a significant part of our lives to UFO's, myself trying to spread this reality in the best way. Stefano trying to understand its roots, both being aware of how important the phenomenon is. And so I have acted as a midwife to the important result of Stefano's work, being convinced that reading this book is at the same time necessary and useful. Roberto Pinotti-Director, Centro Ufologico Nationale (CUN), Italy This book, based upon memories of experiences covering a period of many years, is charming above all for it concerns the contact, first, and then the coexistence of humans and aliens, working toward a single goal.

Download or read book Electrical Contacts written by Milenko Braunovic and published by CRC Press. This book was released on 2017-12-19 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various factors affect the performance of electrical contacts, including tribological, mechanical, electrical, and materials aspects. Although these behaviors have been studied for many years, they are not widely used or understood in practice. Combining approaches used across the globe, Electrical Contacts: Fundamentals, Applications, and Technology integrates advances in research and development in the tribological, material, and analytical aspects of electrical contacts with new data on electrical current transfer at the micro- and nanoscales. Taking an application-oriented approach, the authors illustrate how material characteristics, tribological behavior, and loading impact the degradation of contacts, formation of intermetallics, and overall reliability and performance. Coverage is divided broadly into three sections, with the first focused on mechanics, tribology, materials, current and heat transfer, and basic reliability issues of electrical contacts. The next section explores applications, such as power connections, electronic connections, and sliding contacts, while the final section presents the diagnostic and monitoring techniques used to investigate and measure phenomena occurring at electrical contact interfaces. Numerous references to current literature reflect the fact that this book is the most comprehensive survey in the field. Explore an impressive collection of data, theory, and practical applications in Electrical Contacts: Fundamentals, Applications, and Technology, a critical tool for anyone investigating or designing electrical equipment with improved performance and reliability in mind.

Download or read book Numerics of Unilateral Contacts and Friction written by Christian Studer and published by Springer Science & Business Media. This book was released on 2009-05-06 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanics provides the link between mathematics and practical engineering app- cations. It is one of the oldest sciences, and many famous scientists have left and will leave their mark in this fascinating ?eld of research. Perhaps one of the most prominentscientists in mechanics was Sir Isaac Newton, who with his “laws of - tion” initiated the description of mechanical systems by differential equations. And still today, more than 300 years after Newton, this mathematical concept is more actual than ever. The rising computer power and the development of numerical solvers for diff- ential equations allowed engineersall over the world to predict the behavior of their physical systems fast and easy in an numerical way. And the trend to computational simulation methods is still further increasing, not only in mechanics, but practically in all branches of science. Numerical simulation will probablynot solve the world’s engineering problems, but it will help for a better understanding of the mechanisms of our models.
Download or read book Electric Contacts written by Ragnar Holm and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a completely revised and rewritten edition of "Electric Contacts Handbook" published in 1958. A large number of new in vestigations are considered, and many of the basic theories are revised in detail and even in general. The body of information had to be limited as it was not advisable to increase the volume of the book. In particular, no attempt was made to cover all of the practical applications. They appear as examples following concentrated explanations of basic phenomena. As in several branches of technology, the solutions of problems ari sing in the field of electric contacts involve insight into various disci plines of physics. It is feit that reviews of some of those topics, especi ally adapted to electric contact phenomena, are welcome to many readers. For example, chapters have been devoted to the structure of carbon, the band theory of electric conduction in solids, certain pro blems in statistics, and the theory of the electric arc. As regards arc problems, new ideas have been introduced. In order to make the main text less cumbersome, such reviews are presented as appendices. Throughout this edition, the mksa-unit system is used in accord with the latest recommendation for standardization of units in scientific and technical writings. The chapter "History of Early Investigations on Contacts" forming Part IV in the preceding edition of 1958 has not been repeated in this book.
Download or read book Multibody Dynamics with Unilateral Contacts written by Friedrich Pfeiffer and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: As mechanical systems become more complex so do the mathematical models and simulations used to describe the interactions of their parts. One area of multibody theory that has received a great deal of attention in recent years is the dynamics of multiple contact situations occurring in continuous joints and couplings. Despite the rapid gains in our understanding of what occurs when continuous joints and couplings interact, until now there were no books devoted exclusively to this intriguing phenomenon. Focusing on the concerns of practicing engineers, Multibody Dynamics with Unilateral Contacts presents all theoretical and applied aspects of this subject relevant to a practical understanding of multiple unilateral contact situations in multibody mechanical systems. In Part 1, Professor Pfeiffer and Dr. Glocker provide an exhaustive review of the laws and principles governing the dynamics of unilateral contacts in multibody mechanical and technical systems. Among the topics covered are multibody and contact kinematics, the dynamics of rigid body systems, multiple contact configurations, detachment and stick-slip transitions, frictionless impacts, impacts with friction, and the Corner law of contact dynamics. In Part 2, the authors present numerous applications of the theories presented in Part 1. Each chapter in this part is devoted to a different law, theory, or model, such as discontinuous force laws, classical impact theory, Coulomb's friction law, and mechanical and mathematical models of impacts and friction. In addition, each chapter features several practical examples that allow engineers to observe the concepts described in action. Examples are drawn from a broad array of fields and range from hammering in gears as occurring in a synchronous generator to impacts and friction as observed in a child's woodpecker toy, from a demonstration of classical impact theory using an automobile gear box example, to Coulomb's friction law as applied to a turbine blade damper. Multibody Dynamics with Unilateral Contacts is an indispensable resource for mechanical engineers working on all types of multibody systems and the friction and vibration problems that can occur in them. It is also a valuable reference for researchers studying nonlinear dynamics. The only book devoted entirely to the theory and applications of onE of the most crucial aspects of multibody system design. This is the first book to focus exclusively on the theory and applications of multiple contact situations occurring in continuous joints and couplings in multibody systems. As such, it is a valuable resource for engineers working on mechanical systems with interrelated multiple parts. Multibody Dynamics with Unilateral Contacts * Provides a comprehensive examination of the laws and principles governing the dynamics of unilateral contacts in multibody mechanical and technical systems. * Presents the latest mathematical models and simulation techniques for describing the interactions of joints and couplings in multibody systems. * Describes practical applications for all the concepts covered. * Includes numerous examples drawn from a wide range of fascinating and enlightening real-world demonstrations, including everything from an airplane's landing gear to a child's toy.
