This book was released on 2012-12-06 with total page 341 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 Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination 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 concerned if the printing and distribution of the volumes were handled by an international 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 Corporation 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 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: Space weather is considered to be conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the reliability and performance of space-borne or ground- based technological systems. Song (environmental earth and atmospheric sciences, U. of Massachusetts), Singer (Space Environment Center, National Oceanic and Atmospheric Administration), and Siscoe (Center for Space Physics, Boston U.) present 50 articles on current understanding and advances in the description and prediction of space weather. Nine of the articles, accessible to non-specialists, touch upon broad issues of space weather in the area of technology, science, industry, and commerce. The remaining articles are geared more towards the scientific community and address the sun and its influence on space weather, specification and prediction of the magnetosphere, and specification and prediction of the ionosphere and thermosphere.

Available in PDF, EPUB and Kindle. Book excerpt: The configuration of the geomagnetic field is an indicator of the response of the magnetosphere to the solar wind input. A number of empirical magnetospheric field models are currently in use which estimate the magnetic field direction and magnitude at any point within the magnetosphere under a variety of conditions. Here, the global nature of the Tsyganenko 89 [Tsyganenko, 1989] magnetospheric magnetic field model is tested by comparison of the model-predicted field orientations with the field orientations derived simultaneously at two different locations in geosynchronous orbit from the axis of symmetry of the plasma electron distribution function (30 eV--40 keV). The results for the particular time interval studied are inconclusive because the Tsyganenko 89 model does not describe the field at one of the satellites well enough, but the procedure itself appears promising.

Available in PDF, EPUB and Kindle. Book excerpt: Empirical mode which estimate the magnetic field direction and magnitude at any point within the magnetosphere under a variety of conditions play an important role in space weather forecasting. We report here on a number of different studies aimed at quantitatively evaluating these models, and in particular the Tsyganenko T89a model. The models are evaluated in two basic ways: (1) by comparing the range of magnetic field tilt angles observed at geosynchronous orbit with the ranges predicted for the same locations by the models; and (2) by comparing the observed magnetic field mapping between the ionosphere and geosynchronous orbit (using two-satellite magnetic field conjunctions) with the model predictions at the same locations. We find that while the T89a model predicts reasonably well the basic variation in tilt angle with local time and permits a range of field inclinations adequate to encompass the majority of observed angles on the dawn, dusk, and night sides, it is unable to reproduce the range of inclinations on the dayside. The model also predicts a smaller magnetic latitude range of geosynchronous field line footpoints than the observed two-satellite mapping indicate. Together, these results suggest that the next generation of field models should allow a greater range of stretching, especially in local time sectors away from midnight. It is important to note, however, that any increased range should encompass less-stretched configurations: although there are certainly cases where the models are not sufficiently stretched, we find that on average all magnetic field models tested, including T89a, are too stretched. Finally, in investigating how well the observed degree of field stretch was ordered by various magnetospheric indices, we find that the tilt of the field at geosynchronous orbit is a promising candidate for the incorporation into future models.

This book was released on 2019-10-15 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to geomagnetic storms and the hazards they pose at the Earth’s surface Geomagnetic storms are a type of space weather event that can create Geomagnetically Induced Currents (GICs) which, once they reach Earth’s surface, can interfere with power grids and transport infrastructure. Understanding the characteristics and impacts of GICs requires scientific insights from solar physics, magnetospheric physics, aeronomy, and ionospheric physics, as well as geophysics and power engineering. Geomagnetically Induced Currents from the Sun to the Power Grid is a practical introduction for researchers and practitioners that provides tools and techniques from across these disciplines. Volume highlights include: Analysis of causes of geomagnetic storms that create GICs Data and methods used to analyze and forecast GIC hazard GIC impacts on the infrastructure of the bulk power system Analysis techniques used in different areas of GIC research New methods to validate and predict GICs in transmission systems
