Noise Control of the Beginning and Development Dynamics of Accidents
by Telman AlievThis book examines noise-monitoring technologies and tools for registering the threshold of development of the latent period of the transition of a facility or product into an emergency state and controlling the dynamics of this development. It also describes how the use of noise technology can improve the accuracy of the results of traditional methods employed in the analysis of noisy signals. Dr. Aliev analyzes the varieties and stages of the generation and development of defects preceding accidents of technical facilities and devices. He shows that registration of the beginning of the latent period in the transition to an emergency state, based on the results of traditional data analysis technologies used in monitoring systems, is sometimes belated due to the impossibility of analyzing the noise correlated with the useful signal. The volume further includes algorithms and technologies for computing estimates of correlation functions, spectral characteristics, and other characteristics of noise.Aimed at professionals and students from a range of fields, including facility and product design engineering, computer science, computational mathematics, control and management systems, geophysics, construction, energy, and medicine, the book provides numerous examples of noise-control intelligent systems.

Noise-Controlling Casings
by Marek PawelczykNoise-Controlling Casings provides detailed noise-controlling strategies for devices generating excessive noise. The main three categories are passive, semi-active and active, and are applicable to a wide range of devices, with applications including vehicle or aircraft cabins. With noise pollution a pressing concern worldwide, this book uses cutting edge technology to provide methods to reduce noise at the source. Some of the most common noise and vibration sources are devices and machinery, but commonly used sound-absorbing methods are ineffective, often causing further problems such as increased size, weight and potential to overheat. This book solves these issues by providing three types of solutions: passive, semi-active and active. Focusing on global noise reduction, compact technology and efficiency, the research presented acts directly at the source, isolating it acoustically from the environment. Proposing a range of specific control strategies for noise-controlling casings, the book provides a theoretical background to the research, looking at system configurations, signal processing implementation and numerical analysis. This book will be of interest to professionals and students in the fields of acoustics, signal processing, automotive and aircraft engineering.

Noise signals: Modelling and Analyses (Studies in Systems, Decision and Control #567)
by Vitalii Babak Artur Zaporozhets Yurii Kuts Mykhailo Fryz Leonid ScherbakThe book meticulously details a constructive mathematical model of a stochastic noise process, specifically a linear random process and its characteristics. Theoretical reasoning on the relationship between random processes with independent increments and those with independent values, known as random processes of white noise, is provided. The model of a linear random process serves as a mathematical representation of colored noises in various hues. Characteristics of both non-stationary and stationary linear random processes are elucidated, with emphasis on their ergodic properties, crucial for practical applications. The study also encompasses the vector linear random process, portraying a model of multi-channel noise signals. A novel contribution to the theory of random functions is the development of a constructive model of a conditional linear random process. This involves determining its distribution laws in the form of a characteristic function and relevant statistical characteristics, which can serve as potential indicators for identifying stochastic noise processes. The book revisits research on periodic stochastic models, examining cyclic, rhythmic, natural, and artificial phenomena, processes, and signals. A comprehensive analysis of the linear periodic random process is conducted, and the identification characteristics of periodic models of stochastic noise signals are explored. Significant attention is directed toward employing contour and phase methods as a theoretical foundation for addressing narrow-band noise signal identification challenges.
Noise Tolerant Data Authentication for Wireless Communication (Signals And Communication Technology)
by Natasa Zivic Obaid Ur-RehmanThis book provides insight into the challenges in providing data authentication over wireless communication channels. The authors posit that established standard authentication mechanisms – for wired devices – are not sufficient to authenticate data, such as voice, images, and video over wireless channels. The authors propose new mechanisms based on the so-called soft authentication algorithms, which tolerate some legitimate modifications in the data that they protect. The authors explain that the goal of these algorithms is that they are tolerant to changes in the content but are still able to identify the forgeries. The authors go on to describe how an additional advantage of the soft authentication algorithms is the ability to identify the locations of the modifications and correct them if possible. The authors show how to achieve this by protecting the data features with the help of error correcting codes. The correction methods are typically based on watermarking, as the authors discuss in the book.Provides a discussion of data (particularly image) authentication methods in the presence of noise experienced in wireless communication;Presents a new class of soft authentication methods, instead of the standard hard authentication methods, used to tolerate minor changes in image data;Features authentication methods based on the usage of authentication tags as well as digital watermarks.
