Download or read book Statistical Signal Processing in Engineering written by Umberto Spagnolini and published by John Wiley & Sons. This book was released on 2018-02-05 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: A problem-solving approach to statistical signal processing for practicing engineers, technicians, and graduate students This book takes a pragmatic approach in solving a set of common problems engineers and technicians encounter when processing signals. In writing it, the author drew on his vast theoretical and practical experience in the field to provide a quick-solution manual for technicians and engineers, offering field-tested solutions to most problems engineers can encounter. At the same time, the book delineates the basic concepts and applied mathematics underlying each solution so that readers can go deeper into the theory to gain a better idea of the solution’s limitations and potential pitfalls, and thus tailor the best solution for the specific engineering application. Uniquely, Statistical Signal Processing in Engineering can also function as a textbook for engineering graduates and post-graduates. Dr. Spagnolini, who has had a quarter of a century of experience teaching graduate-level courses in digital and statistical signal processing methods, provides a detailed axiomatic presentation of the conceptual and mathematical foundations of statistical signal processing that will challenge students’ analytical skills and motivate them to develop new applications on their own, or better understand the motivation underlining the existing solutions. Throughout the book, some real-world examples demonstrate how powerful a tool statistical signal processing is in practice across a wide range of applications. Takes an interdisciplinary approach, integrating basic concepts and tools for statistical signal processing Informed by its author’s vast experience as both a practitioner and teacher Offers a hands-on approach to solving problems in statistical signal processing Covers a broad range of applications, including communication systems, machine learning, wavefield and array processing, remote sensing, image filtering and distributed computations Features numerous real-world examples from a wide range of applications showing the mathematical concepts involved in practice Includes MATLAB code of many of the experiments in the book Statistical Signal Processing in Engineering is an indispensable working resource for electrical engineers, especially those working in the information and communication technology (ICT) industry. It is also an ideal text for engineering students at large, applied mathematics post-graduates and advanced undergraduates in electrical engineering, applied statistics, and pure mathematics, studying statistical signal processing.

Download or read book Battlefield Acoustics written by Thyagaraju Damarla and published by Springer. This book was released on 2015-03-24 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents all aspects of situational awareness using acoustic signals. It starts by presenting the science behind understanding and interpretation of sound signals. The book then goes on to provide various signal processing techniques used in acoustics to find the direction of sound source, localize gunfire, track vehicles and detect people. The necessary mathematical background and various classification and fusion techniques are presented. The book contains majority of the things one would need to process acoustic signals for all aspects of situational awareness in one location. The book also presents array theory, which is pivotal in finding the direction of arrival of acoustic signals. In addition, the book presents techniques to fuse the information from multiple homogeneous/heterogeneous sensors for better detection. MATLAB code is provided for majority of the real application, which is a valuable resource in not only understanding the theory but readers can also use the code as a spring-board to develop their own application based software code.

Download or read book Crimes in Outer Space written by G. S. Sachdeva and published by Springer Nature. This book was released on 2023-07-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book flags and contemplates the lurking problem of space crimes that may escalate and expand with diversification of space activities, greater footfall on the celestial bodies and passage of time, for the lack of appropriate solutions. ​It appraises the incumbent problems to evolve solutions and make recommendations regarding space crime situations. Recognizing current situation where commercial space travel has commenced, and space tourism is not far behind, the book takes a pole position on discussing the topic with its endemic challenges. Space transportation is expected to lead to commercial mining of celestial mineral resources from the Moon and asteroids, as has been found technically feasible and commercially viable. Space-specific products have been identified for industrial mining, processing, and manufacturing, for which manpower would be necessary, howsoever minimal, despite artificial intelligence devices. Blueprints for space habitations on the Moon and Mars are being prepared. In this scenario, where outer space and celestial bodies may soon be inhabited by multi-nationality, multi-ethnic and multi-cultural groupings of tourists, workers, and residents, given cramped and not so comfortable or private living spaces, attitudinal disparities and conflicting beliefs, differences, disputes, conflicts, and crimes are sure to raise their head. Economic activity and business culture may usher in crimes of competition and spying on intellectual property. Space crimes through technologies like cyber, lasers, etc., may also permeate the space domain for ill-intentioned abuses. The criminals may be individuals or collective groups or incognito terrorists. The book also discusses crimes and near-crimes that have already occurred in space but have been ignored or condoned. Absence of sovereignty on celestial bodies coupled with crimes in space or on celestial bodies, presents problems of jurisdiction, extradition, and other legal procedures. The dilemma of multi-national judicial systems, legal codes and norms of social justice need to be resolved by a specialized treaty reconciling major bends in the existing system vis-à-vis the nature of space crimes. Limitations in handling such crimes by the existing judicial system under established doctrines of international law by International Court of Justice or International Criminal Court, is highlighted in the book. It has strong take-aways for research scholars, law fraternity, diplomatic corps, judicial administration, policy-makers and the political class, enabling them to pro-actively initiate action for suitable answers.

Download or read book Data Depth written by Regina Y. Liu and published by American Mathematical Soc.. This book was released on with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a collection of some of the research presented at the workshop of the same name held in May 2003 at Rutgers University. The workshop brought together researchers from two different communities: statisticians and specialists in computational geometry. The main idea unifying these two research areas turned out to be the notion of data depth, which is an important notion both in statistics and in the study of efficiency of algorithms used in computational geometry. Many ofthe articles in the book lay down the foundations for further collaboration and interdisciplinary research.
