The mathematical basis of signal processing and its many areas of application is the subject of this book. Based on a series of graduatelevel lectures held at the Mathematical Sciences Research Institute, the volume emphasizes current challenges, new techniques adapted to new technologies, and certain recent advances in algorithms and theory.
Underlying many of the current mathematical opportunities in digital signal processing are unsolved analog signal processing problems. For instance, digital signals for communication or sensing must map into an analog format for transmission through a physical layer. In this layer we meet a canonical example of analog signal processing: the electrical engineer’s impedance matching problem. Impedance matching is the design of analog signal processing circuits to minimize loss and distortion as the signal moves from its source into the propagation medium. This paper works the matching problem from theory to sampled data, exploiting links between H1 theory, hyperbolic geometry, and matching circuits. We apply J. W. Helton’s significant extensions of operator theory, convex analysis, and optimization theory to demonstrate new approaches and research opportunities in this fundamental problem. 


Bioprocessing of Renewable Resources to Commodity Bioproducts
This book provides the vision of a successful biorefinery—the lignocelluloic biomass needs to be efficiently converted to its constituent monomers, comprising mainly of sugars such as glucose, xylose, mannose and arabinose. Accordingly, the first part of the book deals with aspects crucial for the pretreatment and hydrolysis of biomass...     Managing Exports: Navigating the Complex Rules, Controls, Barriers, and Laws“We have met the enemy, and they are us,” said Pogo the Possum. Nowhere is this more true than in exporting.
Exporters walk a narrow line between everchanging government regulations (ours and others), complex product standards, transportation changes, exchange rate fluctuations, and punitive import duties—all played...
