Can Silefonid withhold the attack of three hundred elite troopers from the Opus Domini? Will Namuh, Eadinac, Lamina and others be able to work together and harness the power of the five Spirit Stones? What evil ploy might Salima generate to disturb the group dynamic?
"The Guide to GPS Positioning is a self-contained introduction to the Global Positioning System, designed to be used in any of the following three ways: as a self-study guide, as lecture notes for formal post-secondary education courses, or as hand-out material to support short-course and seminar presentations on GPS." -- Introduction.
Approximately fifty articles that were published in The Mathematical Intelligencer during its first eighteen years. The selection demonstrates the wide variety of attractive articles that have appeared over the years, ranging from general interest articles of a historical nature to lucid expositions of important current discoveries. Each article is introduced by the editors. "...The Mathematical Intelligencer publishes stylish, well-illustrated articles, rich in ideas and usually short on proofs. ...Many, but not all articles fall within the reach of the advanced undergraduate mathematics major. ... This book makes a nice addition to any undergraduate mathematics collection that does not already sport back issues of The Mathematical Intelligencer." D.V. Feldman, University of New Hamphire, CHOICE Reviews, June 2001.
A unique collection of thirty experiments ranging from ancient astronomy to cosmology, each containing one or more challenges for the reader. The progression here is from the Earth outward through the solar system to the stellar and galactic realm. Topics include the shape of the sky; Stonehenge as a stone-age abacus; determining the size of the Earth; the distance of the moon, stars and planets; planetary mass, density, temperature and atmosphere; the speed of light; the nature of the quiet and active sun; photometry and spectroscopy; star clusters and variable stars; and fundamental properties of stars.
JPL spacecraft antennas-from the first Explorer satellite in 1958 to current R & D Spaceborne Antennas for Planetary Exploration covers the development of Jet Propulsion Laboratory (JPL) spacecraft antennas, beginning with the first Explorer satellite in 1958 through current research and development activities aimed at future missions. Readers follow the evolution of all the new designs and technological innovations that were developed to meet the growing demands of deep space exploration. The book focuses on the radio frequency design and performance of antennas, but covers environmental and mechanical considerations as well. There is additionally a thorough treatment of all the analytical and measurement techniques used in design and performance assessment. Each chapter is written by one or more leading experts in the field of antenna technology. The presentation of the history and technology of spaceborne antennas is aided by several features: * Photographs and drawings of JPL spacecraft * Illustrations to help readers visualize concepts and designs * Tables highlighting and comparing the performance of the antennas * Bibliographies at the end of each chapter leading to a variety of primary and secondary source material This book complements Large Antennas of the Deep Space Network (Wiley 2002), which surveys the ground antennas covered in support of spacecraft. Together, these two books completely cover all JPL antenna technology, in keeping with the JPL Deep Space Communications and Navigation Series mission to capture and present the many innovations in deep space telecommunications over the past decades. This book is a fascinating and informative read for all individuals working in or interested in deep space telecommunications.
Written by a leading scientist with over 35 years of experience working at the National Renewable Energy Laboratory (NREL), Solar Radiation: Practical Modeling for Renewable Energy Applications brings together the most widely used, easily implemented concepts and models for estimating broadband and spectral solar radiation data. The author addresses various technical and practical questions about the accuracy of solar radiation measurements and modeling. While the focus is on engineering models and results, the book does review the fundamentals of solar radiation modeling and solar radiation measurements. It also examines the accuracy of solar radiation modeling and measurements. The majority of the book describes the most popular simple models for estimating broadband and spectral solar resources available to flat plate, concentrating, photovoltaic, solar thermal, and daylighting engineering designs. Sufficient detail is provided for readers to implement the models in assorted development environments. Covering the nuts and bolts of practical solar radiation modeling applications, this book helps readers translate solar radiation data into viable, real-world renewable energy applications. It answers many how-to questions relating to solar energy conversion systems, solar daylighting, energy efficiency of buildings, and other solar radiation applications.
In today s increasingly complex cyberspace we see a variety of actors struggling to gain or maintain their position The ubiquitous use of information and communication technologies has had a profound influence on how these actors pursue their goals and interests The 8th International Conference on Cyber Conflict (CyCon 2016) will focus on cyber power as one of the core elements of relations between different stakeholders and will discuss how the traditional concept of power applies to cyberspace Both hard and soft power are being employed to achieve strategic and political goals through technical, legal and economic means But how can we assess such power? How can we ensure that such power remains in the right hands? How can we ensure or enforce cyber power without risking conflict escalation? How can we respond to exercises of this power with the right tools and measures? Is there a way to maintain a balance of power in cyberspace?
