Both principles and engineering practice have been addressed, with more weight placed on algorithm development. This is achieved by providing an in-depth study on sparse sensing for several major multi-sensor array applications such as beam-pattern synthesis, adaptive beamforming, target detection, arrival angle estimation, and dual-functional radar communications. Sparsity sensed in multi-sensor arrays refers to the sparse property of the spatial spectrum sensed. The exploitation of the sparsity in the sensed can significantly enhance the performance of signal processing systems. The comprehensive and systematic treatment of theory and practice in different array applications is one of the major features of the book, which is particularly suited for readers who are interested to learn practical solutions in array signal processing. The book benefits researchers, engineers, and graduate students in the fields of signal processing, electrical engineering, telecommunications, etc. ![]() Free Download Ian Wharton, "Spark for the Fire: How youthful thinking unlocks creativity" English | ISBN: 0857193465 | 2013 | 168 pages | PDF | 2 MB This is the most extraordinary time for people with a desire to make things ![]() Free Download Scott M.

Recognizing the inherent intersectionality of social and historical factors, the book's eight chapters investigate phenomena ranging from forms of address and personal(ized) infinitives to clitics and sibilant systems, extending from Majorca to Mexico, from Panamanian Congo speech to Afro-Andean vernaculars. The volume is particularly recommended for scholars interested in historical linguistics, sociolinguistics, history, sociology, and anthropology in the Spanish-speaking world. Additionally, it will serve as an indispensable guide to students, both at the undergraduate and graduate level, investigating sociohistorical advances in Spanish. ![]() Free Download Ana Fairchild, Juan Mendez, "Spanish Grammar" English | 2006 | ISBN: 0060881577 | EPUB | pages: 256 | 0.2 mb Unlike traditional textbooks, which leave students without a clear understanding of the different tenses and moods, the Collins College Outline for Spanish Grammar is organized conceptually, explaining in detail subjunctive and imperative moods, passive voice, negatives, idioms, and the rules of accentuation. With sections on articles, adjectives, nouns, and verbs, along with a comprehensive vocabulary appendix for quick and easy reference, this is the essential guide to understanding Spanish. Completely revised and updated by Professor Ana Fairchild, this book includes a test yourself section with answers and complete explanations at the end of each chapter. Also included are bibliographies for further reading, as well as numerous vocabulary lists, exercises, and examples. ![]() Free Download Space: The Human Story by Tim Peake English | October 26th, 2023 | ISBN: 1529913519 | 336 pages | True EPUB | 10.24 MB From bestselling author and British astronaut Tim Peake, an inspirational human history of space travel, from the Apollo missions to our future forays to Mars.

Melnikov, Boris I. Reser English | January 2, 2023 | ISBN: 3031139909 | 356 pages | MOBI | 50 Mb This book is devoted to the construction of space group representations, their tabulation, and illustration of their use. Representation theory of space groups has a wide range of applications in modern physics and chemistry, including studies of electron and phonon spectra, structural and magnetic phase transitions, spectroscopy, neutron scattering, and superconductivity. The book presents a clear and practical method of deducing the matrices of all irreducible representations, including double-valued, and tabulates the matrices of irreducible projective representations for all 32 crystallographic point groups. One obtains the irreducible representations of all 230 space groups by multiplying the matrices presented in these compact and convenient to use tables by easily computed factors. A number of applications to the electronic band structure calculations are illustrated through real-life examples of different crystal structures. The book's content is accessible to both graduate and advanced undergraduate students with elementary knowledge of group theory and is useful to a wide range of experimentalists and theorists in materials and solid-state physics. |
