Available in PDF, EPUB and Kindle. Book excerpt: Throughout stellar astronomy, there exist many classes of stars which exhibit various surface inhomogeneities, velocity perturbations, and/or non-spherical geometries, often varying in time. To model spectra for any of these stars requires projecting a model of that star in the sky and deriving a unique specific intensity for each of the various surface features and then summing the resulting contributions to the flux. While this task is relatively straightforward, it is difficult to generalize for all the classes of stars befitting such spectral modeling, and more importantly, it is a computationally expensive task. As such, many different spectral modeling tools have been developed over the years for dealing with any one of a given class of these stars. In this thesis, I present a generalized approach to this task, the GLASS method. Relying on computer graphics techniques and technology, the GLaDoS code is introduced as an implementation of the GLASS method. With its introduction, I show that GLaDoS is capable of generally treating the problem of computing spectra for an array of variable stellar systems, particularly W UMa contact binaries, spotted stars, and non-radially pulsating stars. As further evidence of its robustness in handling time-varying systems, focus is paid to extensively modeling additional systems. In particular, I construct a binary model focusing on the effect radiation from the companion can have on each star, and pulsation modes are identified for gamma Doradus pulsator HD 135825. The binary model requires adequate handling of variable surface inhomogeneities and non-spherical geometries. Mode identification additionally requires treating inhomogeneities, but it additionally necessitates management of the computationally expensive derivation of thousands to millions of unique spectra that can be fit against observed time-series spectra. Together, these modeling efforts present a thorough trial for the GLASS method and GLaDoS code and show them capable of generally handling spectral modeling in a computationally efficient manner.

Download or read book Nuclear Science Abstracts written by and published by . This book was released on 1975 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
Download or read book System Design Modeling and Simulation written by Claudius Ptolemaeus and published by Lee & Seshia. This book was released on 2013-09-27 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a definitive introduction to models of computation for the design of complex, heterogeneous systems. It has a particular focus on cyber-physical systems, which integrate computing, networking, and physical dynamics. The book captures more than twenty years of experience in the Ptolemy Project at UC Berkeley, which pioneered many design, modeling, and simulation techniques that are now in widespread use. All of the methods covered in the book are realized in the open source Ptolemy II modeling framework and are available for experimentation through links provided in the book. The book is suitable for engineers, scientists, researchers, and managers who wish to understand the rich possibilities offered by modern modeling techniques. The goal of the book is to equip the reader with a breadth of experience that will help in understanding the role that such techniques can play in design.
