Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses developments in axial compressor stability modeling over the last several years and related work in active control of rotating stall and surge. Several major themes have emerged during this work. One theme is the interplay between hydrodynamic perturbations in axial compressors and instability inception. The former obey linearized dynamical equations but their resonance and instability can trigger a variety of nonlinear events leading to violent oscillations in the compressor flow. An understanding of the key physical phenomena associated with stall inception as opposed to those governing fully developed stall or surge is critical to alleviating stall by design means or through active control. Another theme is the utility of actuators for understanding compressor stability. Active control work bas prompted the installation of high-response forcing devices in compressors; even without feedback these have yielded much new information about compressor unsteady behavior. Finally the paper reviews the methods and prospects for using active stabilization to extend the stable operating range of compressors, improving their surge margin and thus increasing overall reliability and performance. Experiments have progressed from laboratory scale demonstrations to full-scale rig and engine tests in about a decade. Competing theories about the physical mechanisms the difficulties associated with stabilization and the goals and control techniques for rotating stall have led to a rich research base on which compressor stability and control technology is being built.

Available in PDF, EPUB and Kindle. Book excerpt: Velocity (or rf) compression has been suggested as a technique for bunch compression complementary to the more established technique involving magnetic chicanes and represents an important research item being investigated at the SPARC test facility. One of the aspects of this technique still not sufficiently understood is its possible impact on the microbunching instability. The purpose of this report is to present the analytical framework for investigating this instability in rf compressors. We use methods similar to those successfully applied to magnetic compressors and derive some integral equations yielding the gain for the instability in linear approximation. The focus here is on the derivation of the relevant equations. Although examples of solutions to these equations are provided we defer a more comprehensive discussion of their implication to a future report. The present study is part of a larger effort for a more comprehensive investigation that eventually will include macroparticle simulations and experiments.

Available in PDF, EPUB and Kindle. Book excerpt: Successful thermal modeling of the human eye helps in the early diagnosis of eye abnormalities such as inflammation, cataracts, diabetic retinopathy, and glaucoma-all leading causes of blindness. This book presents a unified work of eye imaging and modeling techniques that have been proposed and applied to ophthalmologic problems. It delves into various morphological, texture, higher order spectra, and wavelet transformation techniques used to extract important diagnostic features from images, which can then be analyzed by a data scientist for automated diagnosis.
