We live in a noisy world! In all applications (telecommunications, hands-free communications, recording, human-machine interfaces, etc.) that require at least one microphone, the signal of interest is usually contaminated by noise and reverberation. As a result, the microphone signal has to be "cleaned" with digital signal processing tools before it is played out, transmitted, or stored. This book is about speech enhancement. Different well-known and state-of-the-art methods for noise reduction, with one or multiple microphones, are discussed. By speech enhancement, we mean not only noise reduction but also dereverberation and separation of independent signals. These topics are also covered in this book. However, the general emphasis is on noise reduction because of the large number of applications that can benefit from this technology. The goal of this book is to provide a strong reference for researchers, engineers, and graduate students who are interested in the problem of signal and speech enhancement. To do so, we invited well-known experts to contribute chapters covering the state of the art in this focused field.

Make cool stuff. If you're a designer or artist without a lot of programming experience, this book will teach you to work with 2D and 3D graphics, sound, physical interaction, and electronic circuitry to create all sorts of interesting and compelling experiences -- online and off. Programming Interactivity explains programming and electrical engineering basics, and introduces three freely available tools created specifically for artists and designers: Processing, a Java-based programming language and environment for building projects on the desktop, Web, or mobile phones Arduino, a system that integrates a microcomputer prototyping board, IDE, and programming language for creating your own hardware and controls OpenFrameworks, a coding framework simplified for designers and artists, using the powerful C++ programming language BTW, you don't have to wait until you finish the book to actually make something. You'll get working code samples you can use right away, along with the background and technical information you need to design, program, build, and troubleshoot your own projects. The cutting edge design techniques and discussions with leading artists and designers will give you the tools and inspiration to let your imagination take flight.

In most college and university libraries, materials published before 1800 have been moved into special collections, while the post-1923 books remain in general circulation. But books published between these dates are vulnerable to deaccessioning, as libraries increasingly reconfigure access to public-domain texts via digital repositories such as Google Books. Even libraries with strong commitments to their print collections are clearing out the duplicates, assuming that circulating copies of any given nineteenth-century edition are essentially identical to one another. When you look closely, however, you see that they are not. Many nineteenth-century books were donated by alumni or their families decades ago, and many of them bear traces left behind by the people who first owned and used them. In Book Traces, Andrew M. Stauffer adopts what he calls "guided serendipity" as a tactic in pursuit of two goals: first, to read nineteenth-century poetry through the clues and objects earlier readers left in their books and, second, to defend the value of keeping the physical volumes on the shelves. Finding in such books of poetry the inscriptions, annotations, and insertions made by their original owners, and using them as exemplary case studies, Stauffer shows how the physical, historical book enables a modern reader to encounter poetry through the eyes of someone for whom it was personal.

Dr. Greg Zacharias, former Chief Scientist of the United States Air Force (2015-18), explores next steps in autonomous systems (AS) development, fielding, and training. Rapid advances in AS development and artificial intelligence (AI) research will change how we think about machines, whether they are individual vehicle platforms or networked enterprises. The payoff will be considerable, affording the US military significant protection for aviators, greater effectiveness in employment, and unlimited opportunities for novel and disruptive concepts of operations. Autonomous Horizons: The Way Forward identifies issues and makes recommendations for the Air Force to take full advantage of this transformational technology.

This book explores “making” in the school curriculum in a period in which the ability to create and respond to digital artifacts is key and focuses on makerspaces in educational settings. Combining the arts with design to give a fuller picture of the engagement and wonder that unfolds with maker literacies, the book moves across such settings and themes as: Creativity and writing in classrooms Making and developing civic engagement Emotional experiences of making Race and gender in makerspace Game-based play and coding in schools and draws its case studies from the Netherlands, Finland, Canada, Australia, the United Kingdom, and the United States. Giving as broad a perspective on makerspaces, making, and design as possible, the book will help scholars expand their understandings and help educators appreciate the power and worth of making to inspire students. It is useful for anyone hoping to apply design, maker, and makerspace approaches to their teaching and learning.

A practical guide to research for architects and designers—now updated and expanded! From searching for the best glass to prevent glare to determining how clients might react to the color choice for restaurant walls, research is a crucial tool that architects must master in order to effectively address the technical, aesthetic, and behavioral issues that arise in their work. This book's unique coverage of research methods is specifically targeted to help professional designers and researchers better conduct and understand research. Part I explores basic research issues and concepts, and includes chapters on relating theory to method and design to research. Part II gives a comprehensive treatment of specific strategies for investigating built forms. In all, the book covers seven types of research, including historical, qualitative, correlational, experimental, simulation, logical argumentation, and case studies and mixed methods. Features new to this edition include: Strategies for investigation, practical examples, and resources for additional information A look at current trends and innovations in research Coverage of design studio–based research that shows how strategies described in the book can be employed in real life A discussion of digital media and online research New and updated examples of research studies A new chapter on the relationship between design and research Architectural Research Methods is an essential reference for architecture students and researchers as well as architects, interior designers, landscape architects, and building product manufacturers.

A basic problem in computer vision is to understand the structure of a real world scene given several images of it. Techniques for solving this problem are taken from projective geometry and photogrammetry. Here, the authors cover the geometric principles and their algebraic representation in terms of camera projection matrices, the fundamental matrix and the trifocal tensor. The theory and methods of computation of these entities are discussed with real examples, as is their use in the reconstruction of scenes from multiple images. The new edition features an extended introduction covering the key ideas in the book (which itself has been updated with additional examples and appendices) and significant new results which have appeared since the first edition. Comprehensive background material is provided, so readers familiar with linear algebra and basic numerical methods can understand the projective geometry and estimation algorithms presented, and implement the algorithms directly from the book.
