DFT-Domain Based Single-Microphone Noise Reduction for Speech Enhancement (Synthesis Lectures on Speech and Audio Processing)
by Richard C. Hendriks Timo Gerkmann Jesper JensenAs speech processing devices like mobile phones, voice controlled devices, and hearing aids have increased in popularity, people expect them to work anywhere and at any time without user intervention. However, the presence of acoustical disturbances limits the use of these applications, degrades their performance, or causes the user difficulties in understanding the conversation or appreciating the device. A common way to reduce the effects of such disturbances is through the use of single-microphone noise reduction algorithms for speech enhancement. The field of single-microphone noise reduction for speech enhancement comprises a history of more than 30 years of research. In this survey, we wish to demonstrate the significant advances that have been made during the last decade in the field of discrete Fourier transform domain-based single-channel noise reduction for speech enhancement.Furthermore, our goal is to provide a concise description of a state-of-the-art speech enhancement system, and demonstrate the relative importance of the various building blocks of such a system. This allows the non-expert DSP practitioner to judge the relevance of each building block and to implement a close-to-optimal enhancement system for the particular application at hand.

Although the work is focused on the Megacity of Dhaka in Bangladesh, the techniques and methods that are used to research these issues can be utilized in any other areas where rapid population growth coupled with unplanned urbanization is leading to environmental degradation. The book is useful for people working in the area of Geospatial Science, Urban Geography, Environmental Management and International Development. Since the chapters in the book cover a range of environmental issues, this book describes useful tools for assisting informed decision making, particularly in developing countries.
The Diabetic Patient Agent: Modeling Disease in Humans and the Healthcare System Response (Intelligent Systems Reference Library #133)
by Raman Paranjape Zhanle Gerald Wang Simerjit GillThis book provides a pioneering approach to modeling the human diabetic patient using a software agent. It is based on two MASc (Master of Applied Science) theses: one looking at the evolution of the patient agent in time, and another looking the interaction of the patient agent with the healthcare system. It shows that the software agent evolves in a manner analogous to the human patient and exhibits typical attributes of the illness such as reacting to food consumption, medications, and activity. This agent model can be used in a number of different ways, including as a prototype for a specific human patient with the purpose of helping to identify when that patient’s condition deviates from normal variations. The software agent can also be used to study the interaction between the human patient and the health care system. This book is of interest to anyone involved in the management of diabetic patients or in societal research into the management of diabetes. The diabetic patient agent was developed using the Ackerman model for diabetes, but this model can be easily adapted for any other model subject with the necessary physiological data to support that model.
Diablo Mesa (Nora Kelly)
by Douglas Preston Lincoln ChildFan favourites Nora Kelly and Corrie Swanson return in the new thriller from international bestsellers Preston & Child. Forced to leave her post at the Santa Fe Archaeological Institute, Nora Kelly is left without a job and without any prospects. So when billionaire Lucas Tappan invites her to lead his excavation of the infamous Roswell landing site, she has no choice but to make a decision that could destroy her reputation.Armed with a healthy dose of scepticism, Nora reluctantly agrees to visit. When the preliminary scans of the area reveal a suspected Native American burial site, Nora takes a closer look.But this is no indigenous burial site. It's a crime scene, and a recent one at that. Nora uncovers two dead bodies, one with a bullet hole in its skull, acid used to conceal the identities. Dead bodies mean this has become a case for the FBI, and Nora knows just the person to investigate – Special Agent Corrie Swanson.As Corrie and Nora dig deeper into the mystery, they will uncover more questions than answers. And the truth they seek will be even stranger than the conspiracy it hides behind...'Down-to-earth action tackles an otherworldly mystery in this devilishly plausible yarn' KIRKUS starred review

Diachronic Perspectives on Embodiment and Technology: Gestures and Artefacts (Philosophy of Engineering and Technology #46)
by Thiemo Breyer Alexander Matthias Gerner Niklas Grouls Johannes F. M. SchickThis book investigates the relationships between gestures and artefacts theoretically and historically, by analyzing different phenomena stemming from a variety of fields such as robotics, archaeology, gesture studies, anthropology, philosophy, and gestural practices like choreography, music performance, and composition. It underlines how embodiment and technology change the interplay between maker and artefact over time and appeals to students and researchers in these fields. Its goal is to enable the reader to understand that the recurring topics and questions as well as multi-level similarities are by no means accidental, but can best be understood if one pays attention to the intertwinements of materiality and cognition, praxis and techne.
Diagnosability, Security and Safety of Hybrid Dynamic and Cyber-Physical Systems
by Moamar Sayed-MouchawehCyber-physical systems (CPS) are characterized as a combination of physical (physical plant, process, network) and cyber (software, algorithm, computation) components whose operations are monitored, controlled, coordinated, and integrated by a computing and communicating core. The interaction between both physical and cyber components requires tools allowing analyzing and modeling both the discrete and continuous dynamics. Therefore, many CPS can be modeled as hybrid dynamic systems in order to take into account both discrete and continuous behaviors as well as the interactions between them. Guaranteeing the security and safety of CPS is a challenging task because of the inherent interconnected and heterogeneous combination of behaviors (cyber/physical, discrete/continuous) in these systems. This book presents recent and advanced approaches and tech-niques that address the complex problem of analyzing the diagnosability property of cyber physical systems and ensuring their security and safety against faults and attacks. The CPS are modeled as hybrid dynamic systems using different model-based and data-driven approaches in different application domains (electric transmission networks, wireless communication networks, intrusions in industrial control systems, intrusions in production systems, wind farms etc.). These approaches handle the problem of ensuring the security of CPS in presence of attacks and verifying their diagnosability in presence of different kinds of uncertainty (uncertainty related to the event occurrences, to their order of occurrence, to their value etc.).

Diagnosing Hemp and Cannabis Crop Diseases
by Dr Shouhua WangHemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s). The book provides: ·A field and laboratory guide to diagnosing hemp and cannabis diseases and pest problems ·Ready-to-adopt skills, methods and protocols in plant diagnosis, which can be applied to other crops ·Over 300 colour photographs accompanied by a wealth of disease information, including field observations, unique symptoms, microscopic details, and molecular data. This book is essential for anyone who is interested in learning about Cannabis crop diseases, for crops grown in the field, and in indoor production facilities.
Diagnosis: Interpreting the Shadows
by Pat Croskerry Karen Cosby Mark L. Graber Hardeep SinghDespite diagnosis being the key feature of a physician's clinical performance, this is the first book that deals specifically with the topic. In recent years, however, considerable interest has been shown in this area and significant developments have occurred in two main areas: a) an awareness and increasing understanding of the critical role of clinical decision making in the process of diagnosis, and of the multiple factors that impact it, and b) a similar appreciation of the role of the healthcare system in supporting clinicians in their efforts to make accurate diagnoses. Although medicine has seen major gains in knowledge and technology over the last few decades, there is a consensus that the diagnostic failure rate remains in the order of 10-15%. This book provides an overview of the major issues in this area, in particular focusing on where the diagnostic process fails, and where improvements might be made.

Diagnosis and Control of Diseases of Fish and Shellfish
by Brian Austin Aweeda Newaj-FyzulThere has been a continual expansion in aquaculture, such that total production is fast approaching that of wild-caught fisheries. Yet the expansion is marred by continued problems of disease. New pathogens emerge, and others become associated with new conditions. Some of these pathogens become well established, and develop into major killers of aquatic species. Diagnosis and Control of Diseases of Fish and Shellfish focuses on the diagnosis and control of diseases of fish and shellfish, notably those affecting aquaculture. Divided into 12 chapters, the book discusses the range of bacterial, viral and parasitic pathogens, their trends, emerging problems, and the relative significance to aquaculture. Developments in diagnostics and disease management, including the widespread use of serological and molecular methods, are presented. Application/dose and mode of action of prebiotics, probiotics and medicinal plant products used to control disease are examined, as well as the management and hygiene precautions that can be taken to prevent/control the spread of disease. This book will be a valuable resource for researchers, students, diagnosticians, veterinarians, fish pathologists and microbiologists concerned with the management of diseases of fish and shellfish.

Diagnosis and Fault-Tolerant Control
by Mogens Blanke Michel Kinnaert Jan Lunze Marcel StaroswieckiFault-tolerant control aims at a gradual shutdown response in automated systems when faults occur. It satisfies the industrial demand for enhanced availability and safety, in contrast to traditional reactions to faults, which bring about sudden shutdowns and loss of availability.The book presents effective model-based analysis and design methods for fault diagnosis and fault-tolerant control. Architectural and structural models are used to analyse the propagation of the fault through the process, to test the fault detectability and to find the redundancies in the process that can be used to ensure fault tolerance. It also introduces design methods suitable for diagnostic systems and fault-tolerant controllers for continuous processes that are described by analytical models of discrete-event systems represented by automata. The book is suitable for engineering students, engineers in industry and researchers who wish to get an overview of the variety of approaches to process diagnosis and fault-tolerant control.The authors have extensive teaching experience with graduate and PhD students, as well as with industrial experts. Parts of this book have been used in courses for this audience. The authors give a comprehensive introduction to the main ideas of diagnosis and fault-tolerant control and present some of their most recent research achievements obtained together with their research groups in a close cooperation with European research projects.The third edition resulted from a major re-structuring and re-writing of the former edition, which has been used for a decade by numerous research groups. New material includes distributed diagnosis of continuous and discrete-event systems, methods for reconfigurability analysis, and extensions of the structural methods towards fault-tolerant control. The bibliographical notes at the end of all chapters have been up-dated. The chapters end with exercises to be used in lectures.
