Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis was to explore the feasibility of replacing a manual audio equalizer with an adaptive filter that adaptively equalizes the spectral distortion of an audio system. The impulse response of an audio system which includes the response of the speaker crossover network, the power amplifiers, speakers, and the acoustic transfer function between the system's input signal spectrum. The Adaptive Inverse Pre-filter, the Filtered-x algorithm, and the Adaptive Inverse Modeling Control System are investigated which remove the distortion by pre-filtering the audio system's input signal with the audio system's inverse. The audio system examined is the Armstrong Aerospace Medical research Laboratory's Performance and Communication Research and Technology reverberation chamber located at Wright-Patterson Air Force Base. Keywords: Digital filters; Adaptive filters; Audio frequency; Equalization. (jes).

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2006 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This doctoral dissertation in computer science describes how traditional chalk and talk lectures can be transmitted over the web while maximizing the quality and minimizing the amount of extra effort. The book presents a comprehensive discussion on many technological and humand-centered issues using the example of the software system "E-Chalk" that was co-developed by the author. As a by-product, the work includes a detailed description of the so-called "Simple Interactive Object Extration (SIOX)" algorithm that has recently been integrated in several open-source image manipulation programs such as GIMP, Inkscape, and Blender.

This book was released on 1992 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a solution for the problem of acoustic equalization. Acoustic data are collected from a microphone at a listener location, and compared with a source (CD player). An adaptive signal processing algorithm, based on the Least Mean Squares (LMS), warps the CD signal to account for the filtering effects of the listening room. The algorithm to adapt the coefficients of a multirate equalizer is computationally efficient and can be performed in real-time with current microprocessor technology. As music is nonstationary, the LMS algorithm will need to undergo rapid convergence to a new set of optimal filter coefficients each time the input signal statistics change. As the LMS is a gradient descent algorithm, fast convergence implies a step size selection which operates at the algorithm's edge of stability. An analytic expression exists to determine the step size for uncorrelated input data as a function of the maximum eigenvalue of the input data. This dissertation extends this work to cover the case of correlated signals such as music. This result provides verification of heuristic rules that have been proposed i the literature. To date, formulations involving the maximum input signal power have been utilized as an estimate of the maximum eigenvalue. In this dissertation, a new method of determining the maximum eigenvalue is proposed by allowing the LMS algorithm to diverge. For a large and consistent domain of initial condition, iterations, and purposely divergent step sizes, the maximum eigenvalue dominates the rate of algorithm divergence. Simulations were pursued to determine the bounds of these variables for robust operation. This methodology was utilized to analyze the performance of the adaptive equalizer on selected music epochs, and to validate the theory put forward in this dissertation.
