Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.
