Popular among both novice and experienced AutoCAD users, this comprehensive book begins with an overview of the basics of AutoCAD, such as creating drawings, using commands, and specifying coordinates. Coverage becomes more in-depth as each chapter builds off the previous one, with discussions of 2D and 3D drawing techniques, using layers, creating dimensions, 3D coordinates, and rendering. You ll learn to customize commands and toolbars; program AutoCAD using AutoLISP and VBA; and review AutoCAD LT. A "Quick Start" will have beginners creating a CAD drawing on their first day. The accompanying CD-ROM provides before-and-after real-world drawings, bonus appendices, freeware and shareware programs, the book in searchable PDF format, and a 30-day trial version of AutoCAD software.
This book covers every significant AutoCAD and AutoCAD LT feature. If you’re a beginning user, you’ll find everything you need to start out; if you’re already using AutoCAD or AutoCAD LT regularly, the book covers advanced material as well. Although you can use this book as a tutorial if you’re just starting out or learning a new set of features, it also provides a solid reference base to come back to again and again. The short tutorials on almost every topic will quickly have you drawing professionally. The CD-ROM is chock-full of drawings, a trial version of AutoCAD 2007, and add-in programs (which are mostly for AutoCAD only). This book should be all that you need to make full use of either program.

The need for natural and effective Human-Computer Interaction (HCI) is increasingly important due to the prevalence of computers in human activities. Computer vision and pattern recognition continue to play a dominant role in the HCI realm. However, computer vision methods often fail to become pervasive in the field due to the lack of real-time, robust algorithms, and novel and convincing applications. This state-of-the-art contributed volume is comprised of articles by prominent experts in computer vision, pattern recognition and HCI. It is the first published text to capture the latest research in this rapidly advancing field with exclusive focus on real-time algorithms and practical applications in diverse and numerous industries, and it outlines further challenges in these areas. Real-Time Vision for Human-Computer Interaction is an invaluable reference for HCI researchers in both academia and industry, and a useful supplement for advanced-level courses in HCI and Computer Vision.

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.

Digital Communications - Glover & Grant
An up-to-date and comprehensive text on the rapidly expanding field of fixed and mobile communications, including data networks and packet switched systems. The aim of the book is fourfold- (1) to develop the mathematical theory behind signal processing as used in modern digital communications systems, (2) to extend these theoretical signalling concepts into information links which are robust in the presence of noise and other impairment mechanisms, (3) to investigate how these transmission links can be developed into fixed and mobile data communications systems for voice and video transmission, and (4) to develop queuing theory techniques and explore their development in small and large scale data transmission networks such as ISDN. The material is set in an appropriate historical context, and a substantial number of numerical and practical examples are included in the text.
