Book Description
A comprehensive reference giving a thorough explanation of propagation mechanisms, channel characteristics results, measurement approaches and the modelling of channels Thoroughly covering channel characteristics and parameters, this book provides the knowledge needed to design various wireless systems, such as cellular communication systems, RFID and ad hoc wireless communication systems. It gives a detailed introduction to aspects of channels before presenting the novel estimation and modelling techniques which can be used to achieve accurate models. To systematically guide readers through the topic, the book is organised in three distinct parts. The first part covers the fundamentals of the characterization of propagation channels, including the conventional single-input single-output (SISO) propagation channel characterization as well as its extension to multiple-input multiple-output (MIMO) cases. Part two focuses on channel measurements and channel data post-processing. Wideband channel measurements are introduced, including the equipment, technology and advantages and disadvantages of different data acquisition schemes. The channel parameter estimation methods are then presented, which include conventional spectral-based estimation, the specular-path-model based high-resolution method, and the newly derived power spectrum estimation methods. Measurement results are used to compare the performance of the different estimation methods. The third part gives a complete introduction to different modelling approaches. Among them, both scattering theoretical channel modelling and measurement-based channel modelling approaches are detailed. This part also approaches how to utilize these two modelling approaches to investigate wireless channels for conventional cellular systems and some new emerging communication systems. This three-part approach means the book caters for the requirements of the audiences at different levels, including readers needing introductory knowledge, engineers who are looking for more advanced understanding, and expert researchers in wireless system design as a reference. Presents technical explanations, illustrated with examples of the theory in practice Discusses results applied to 4G communication systems and other emerging communication systems, such as relay, CoMP, and vehicle-to-vehicle rapid time-variant channels Can be used as comprehensive tutorial for students or a complete reference for engineers in industry Includes selected illustrations in color Program downloads available for readers Companion website with program downloads for readers and presentation slides and solution manual for instructors Essential reading for Graduate students and researchers interested in the characteristics of propagation channel, or who work in areas related to physical layer architectures, air interfaces, navigation, and wireless sensing

Book Description
Research on humanoid robots has been mostly with the aim of developing robots that can replace humans in the performance of certain tasks. Motion planning for these robots can be quite difficult, due to their complex kinematics, dynamics and environment. It is consequently one of the key research topics in humanoid robotics research and the last few years have witnessed considerable progress in the field. Motion Planning for Humanoid Robots surveys the remarkable recent advancement in both the theoretical and the practical aspects of humanoid motion planning. Various motion planning frameworks are presented in Motion Planning for Humanoid Robots, including one for skill coordination and learning, and one for manipulating and grasping tasks. The problem of planning sequences of contacts that support acyclic motion in a highly constrained environment is addressed and a motion planner that enables a humanoid robot to push an object to a desired location on a cluttered table is described. The main areas of interest include: • whole body motion planning, • task planning, • biped gait planning, and • sensor feedback for motion planning. Torque-level control of multi-contact behavior, autonomous manipulation of moving obstacles, and movement control and planning architecture are also covered. Motion Planning for Humanoid Robots will help readers to understand the current research on humanoid motion planning. It is written for industrial engineers, advanced undergraduate and postgraduate students.

Book Description
These writings are about the common denominator to all languages, and Philosophies called the Ninth Harmonic, ĒBŪLŪ. The BŪLŪ language is Innate to reality. 99% of Biblical Hapax legomenon are in ĒBŪLŪ, Pronounced HEBULU. The reasoning here is anchored onomatopoeically, or should we say harmonically in the The Ninth Harmonic using spoken sounds to reveal the innate wisdom in reality as it is in eternity, revealing that Reality is Inside out Eternity, and Pi at Infinity = 4. Because Infinity is One of a kind and every One is of 4. So that Reality is eternity being revealed in increments of 7th within 3. SO that the meaning of The trinity as 1 in Three is that there is One 7 in the Three called a Third Day, so that there is 1 of the seven in every Three, hence the implication of Pi. Pointing to that all of modern science is upside down.

Book Description
From newborn galaxies to icy worlds and blazing quasars, a behind-the-scenes story of how Palomar Observatory astronomers unveiled our complex universe. Ever since 1936, pioneering scientists at Palomar Observatory in Southern California have pushed against the boundaries of the known universe, making a series of dazzling discoveries that changed our view of the cosmos: quasars, colliding galaxies, supermassive black holes, brown dwarfs, supernovae, dark matter, the never-ending expansion of the universe, and much more. In Cosmic Odyssey, astronomer Linda Schweizer tells the story of the men and women at Palomar and their efforts to decipher the vast energies and mysterious processes that govern our universe. Palomar was the Apollo mission of its era. The first images from the 200-inch George Ellery Hale telescope, commissioned in 1948 as the world's largest, generated as much excitement as images from the moon in 1969 and from the Hubble Space Telescope more recently. So far, Palomar's “Big Eye” and three other telescopes have yielded more than 75,000 telescope-nights of precious data. Schweizer takes readers behind the scenes of scientific discovery, mapping the often chaotic process of detours, dead ends, and serendipitous leaps of insight. Although her focus is on Palomar, she follows threads of discovery across the world to other teams and observatories. Based on more than one hundred interviews and enhanced by research in scientific journals, her account paints a fascinating picture of how discrete insights acquired over decades by researchers in a global community cascade, collide, and finally coalesce into the discoveries we come to accept as facts.

Book Description
M. Rycroft, FacultyMember, InternationalSpaceUniversity e-mail:[email protected] "The Space Transportation Market: Evolution or Revolution?" was the question which was the focus for the papers presented, and also the Panel Discussions, at the fifth annual Symposium organised by the International Space University. Held in Strasbourg, France, for three lively days at the end of May 2000, the Symposium brought together representatives of the developers, providers and operators of space transportation systems, of regulatory bodies, and of users of the space transportation infrastructure in many fields, as well as experts in policy and market analysis. From the papers published here, it is clear that today's answer to the question tends more towards evolution than to revolution. The space launch industry is still not a fully mature one, and is still reliant on at least partial funding by governments. Better cooperation is essential between governments, launch providers, satellite builders and satellite operators in order to reduce the problems which the space transportation market faces today.
