  • The Fourier transform and its extensions have historically been the prime vehi- cle for signal analysis and representation. Since the early 1970s, block transforms with real basis functions, particularly the discrete cosine transform (DCT), have been studied extensively for transform coding applications. The availability of simple fast transform algorithms and good signal coding performance made the DCT the standard signal decomposition technique, particularly for image and video. The international standard image-video coding algorithms, i.e., CCITT...

  • This is a watershed moment in the field of neuroimaging. At least three emerging trends have been slowly reframing the field for the last five years. Each one of these trends intersects with a foundational issue in human brain mapping, affecting the measurement or methodological or theoretical nature of the overall field. First are methodological problems that have arisen concerning nonindependence of samples—in effect the lack of cross-validation procedures applied in the field, especially in social neuroscience (SN).

  • Designing for the disabled is about making buildings accessible to and usable by people with disabilities. Universal design is about making buildings safe and convenient for all their users, including people with disabilities. A theme of this book is the similarities and differences of the two, between their correspondences and affinities on the one hand, and their discordancies and diverse methodologies on the other.

  • This book is about RF system analysis and design at the level that requires an understanding of the interaction between the modules of a system so the ultimate performance can be predicted. It describes concepts that are advanced, that is, beyond those that are more commonly taught, because these are necessary to the understanding of effects encountered in practice. It is about answering questions such as:

  • We have discussed the design and implementation of digital FIR filters in the previous chapter. In this chapter, our attention will be focused on the design, realization, and implementation of digital IIR filters. The design of IIR filters is to determine the transfer function H(z) that satisfies the given specifications. We will discuss the basic characteristics of digital IIR filters, and familiarize ourselves with the fundamental techniques used for the design and implementation of these filters....

  • We normally think of the eye as an organ for vision, but due to the discovery of additional nerve connections from recently-detected novel photoreceptor cells in the eye to the brain, it is now understood how light also mediates and controls a large number of biochemical processes in the human body. The most important findings are related to the control of the biological clock and to the regulation of some important hormones through regular light-dark rhythms. This in turn means that lighting has a large influence on health, well-being and alertness.

  • Finite Impulse Response Filters • • • Introduction to the z-transform Design and implementation of finite impulse response (FIR) filters Programming examples using C and TMS320C6x code The z-transform is introduced in conjunction with discrete-time signals. Mapping from the s-plane, associated with the Laplace transform, to the z-plane, associated with the z-transform, is illustrated. FIR filters are designed with the Fourier series method and implemented by programming a discrete convolution equation.

  • The increasing percentage of digital designers and digital layout experts in the engineering population reflects the directions that our industry is headed. Although the emphasis on digital design is providing significant advances in electronics end products, there is still and will always be a portion of circuit design that interfaces with the analog or real world. There is some similarity in layout strategies between these two domains, but the differences can make an easy circuit layout design less than optimum when trying to achieve good results.

  • As the Internet grows and routing complexity increases, network-level instabilities are becoming more and more common. End-to-end communications are especially susceptible to service disruptions, while diagnosing and mitigating these disruptions are extremely challenging. In this dissertation, we design and build systems for diagnosing routing anomalies and improving robustness of end-to-end communications. The rst piece of this work describes PlanetSeer, a novel distributed system for diagnosing routing anomalies.
