Book excerpt: Using the secret motive power of a lost a lost flying saucer, physicist Micael Arnott, three companions and an escaped convict are flung into the void at eight times the speed of light to eventually land, after the oblivion of acceleration, upon a world that is both extraordinary and terrifying. Their machine disappears and they themselves also vanish one by one, Michael Arnott going first when he is on the verge of explaining the mystery of this far-flung world. That the planet is inhabited seems obvious from queerly designed spaceships glimpsed at intervals, all of them blazoned with a "Z", which is not so much an alphabet letter as a symbol of a master-race of scientists. In their efforts to solve the riddle of the world and system to which they have been hurled, the perplexed travellers gradually realise they are not only involved in an odyssey of space, but in a problem of Time as well. They are forced to the conclusion that, just as the first supersonic airmen paid a penalty of mental blackout for breaking the barrier of sound, so there is also a penalty for exceeding Fitzgerald's Law - namely that 186,000 miles per second is the ultimate possible speed.

Download or read book Formation and Evolution of Galaxy Bulges IAU S245 written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2008-09-04 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulges lie at the heart of most galaxies, the building blocks of our universe. With a selection of reviews and topical presentations, IAU Symposium 245 provides an up-to-date overview of our knowledge on galaxy bulges, and a concise introduction to all current research on the subject. The structure, dynamics, and stellar populations of galaxy bulges, both near and far, are analysed through state-of-the-art observations. The leading models for the formation and evolution of galaxy bulges are described in detail, and the constraints observations put on these are dissected. Particular emphasis is placed on exploring evidence for both hierarchical merging and secular processes. Special attention is also devoted to disentangling the complex web relating galaxy bulges and central supermassive black holes, and on the lessons learned from our exquisite knowledge of the bulge of our own Milky Way. This volume is the best one-stop reference on galaxy bulges currently available.

Download or read book A to Z Geology of India Stratigraphy and Fossils A Bedside Book written by O.P. Mathur and published by Scientific Publishers. This book was released on 2018-01-01 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is in the form of a ready reference. The subject matter of stratigraphy is full of names of formations, groups, etc. At times when we need to know about a certain formation for which we do not know the exact stratigraphic position, then we have to search the entire book, page by page, which becomes quite irritating and time consuming. To overcome this problem, the idea of arranging the different formations in an alphabetic order occurred to the author. During this process it was seen that many small formations, which are otherwise important, do not get their due representation, because they lie in company or association with much larger formations. Otherwise also stratigraphy is nothing but an orderly and chronological arrangement of different formations. In other words, we can say that stratigraphy is a language by itself, where different formations are its words. Same is the case with large number of fossils occurring in different formations. In the usual literature on the subject, it is practically impossible to find in what formation or formations a particular fossil occurs and to which fossil group it belongs. Alphabetical arrangement of fossils as shown in the list of fossils will help students and scholars to persue their task in an easier and quicker way. To arrange such a large number of fossils in an alphabetical order and to find their fossil groups was really a tough job. Still the author does not claim that all the formations and fossils occurring in the Indian stratigraphy are included in this book, and it cannot be the last word on the subject. This is more true in case of fossils, where unlimited literature is available.

Download or read book Introduction to Galaxy Formation and Evolution written by Andrea Cimatti and published by Cambridge University Press. This book was released on 2019-10-17 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Present-day elliptical, spiral and irregular galaxies are large systems made of stars, gas and dark matter. Their properties result from a variety of physical processes that have occurred during the nearly fourteen billion years since the Big Bang. This comprehensive textbook, which bridges the gap between introductory and specialized texts, explains the key physical processes of galaxy formation, from the cosmological recombination of primordial gas to the evolution of the different galaxies that we observe in the Universe today. In a logical sequence, the book introduces cosmology, illustrates the properties of galaxies in the present-day Universe, then explains the physical processes behind galaxy formation in the cosmological context, taking into account the most recent developments in this field. The text ends on how to find distant galaxies with multi-wavelength observations, and how to extract the physical and evolutionary properties based on imaging and spectroscopic data.

Download or read book Formation Tracking Control for Heterogeneous Swarm Systems written by Yongzhao Hua and published by CRC Press. This book was released on 2022-03-10 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swarm system, also known as multi-agent system, refers to a system composed of multiple subsystems (agents) with certain communication, calculation, decision-making, and action capabilities through local information interaction, such as a group of unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), satellites, etc. Formation tracking control of swarm systems is an important technical support and approach for the emergence of swarm intelligence at motion control level. By applying formation tracking control, swarm system agents can adjust their relations in the state or output space through neighboring information interaction, and then the swarm system can achieve favorable space-time conditions for many cooperative tasks such as source seeking, target enclosing, and surveillance. Thus, complex missions can be performed efficiently or cost-effectively. In cross-domain collaborative applications, including air-ground coordination and air-sea coordination, swarm systems are usually composed of several heterogeneous agents, and swarm intelligence can be enhanced by complementary functions of different agents. How to achieve time-varying formation tracking for heterogeneous swarm systems is crucial for cross-domain coordination, which has important theoretical value and practical significance. This important book presents a systematic theoretical approach and control framework on the time-varying formation tracking for high-order heterogeneous swarm systems. Distributed controller design and stability analysis of closed-loop systems for several specific formation tracking problems are provided. Furthermore, the proposed control approaches are applied to practical cooperative experiment platforms composed of UAVs and UGVs, and several formation tracking experiments are carried out to further verify the effectiveness of the theories.

Download or read book Time Varying Formation Tracking Control for Nonlinear Swarm Systems written by Jianglong Yu and published by Springer Nature. This book was released on 2023-07-14 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on time-varying formation control approaches for practical nonlinear swarm systems. Time-varying formation control is the basic guarantee for performing other tasks of swarm systems, such as cooperative decision-making and cooperative detection. However, most practical swarm systems have nonlinear dynamic models. This book studies three typical models of practical nonlinear swarm systems, which represent most of the practical systems and construct the corresponding formation control structure. At the same time, the effects of disturbances, uncertain dynamics, random noise and unknown leader's input are considered and processed to improve the robustness and adaptability. The comprehensive and systematic treatment of practical nonlinear time-varying formation control issues is one of the major features of the book, which is particularly suited for readers who are interested to learn time-varying formation control solutions in nonlinear swarm systems. The book benefits researchers, engineers and graduate students in the fields of formation control, nonlinear control, robust control, etc.

Download or read book Wheeled Mobile Robot Control written by Nardênio Almeida Martins and published by Springer Nature. This book was released on 2021-08-12 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the development and methodologies of trajectory control of differential-drive wheeled nonholonomic mobile robots. The methodologies are based on kinematic models (posture and configuration) and dynamic models, both subject to uncertainties and/or disturbances. The control designs are developed in rectangular coordinates obtained from the first-order sliding mode control in combination with the use of soft computing techniques, such as fuzzy logic and artificial neural networks. Control laws, as well as online learning and adaptation laws, are obtained using the stability analysis for both the developed kinematic and dynamic controllers, based on Lyapunov’s stability theory. An extension to the formation control with multiple differential-drive wheeled nonholonomic mobile robots in trajectory tracking tasks is also provided. Results of simulations and experiments are presented to verify the effectiveness of the proposed control strategies for trajectory tracking situations, considering the parameters of an industrial and a research differential-drive wheeled nonholonomic mobile robot, the PowerBot. Supplementary materials such as source codes and scripts for simulation and visualization of results are made available with the book.
