Feierberg, Michael Andrew EVIDENCE FOR A COMPOSITIONAL RELATIONSHIP BETWEEN ASTEROIDS AND METEORITES FROM INFRARED SPECTRAL REFLECTANCES
High-resolution Fourier spectra in the 0.9-2.5 ym region were measured for sixteen asteroids. These data were combined with 0.3-1.1 um spectrophotometry and 3.0-3.5 urn narrowband photometry for compositional analysis. Comparison spectra of meteorites and terrestrial minerals were measured in the laboratory, some under simulated asteroidal conditions of pressure and temperature. Spectra of elev...

this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
15 صفحه اولPallasitic meteorites: implications regarding the deep structure of asteroids.
Olivine compositions in pallasites exhibit a bimodal distribution and indicate a high degree of internal equilibrium. Cooling rates measured in the metal phases are uniform and consistently lower than those of most iron meteorites. These factors suggest that the pallasites were derived from few parent bodies, and that they crystallized in a highly insulated site-presumably the core of their par...
متن کاملA Variational Approach to Semi-Supervised Clustering
We present a variational inference scheme for semi-supervised clustering in which data is supplemented with side information in the form of common labels. There is no mutual exclusion of classes assumption and samples are represented as a combinatorial mixture over multiple clusters. The method has other advantages such as the ability to find the most probable number of soft clusters in the dat...
متن کاملthe relationship between language and social capital in ilami kurdish: a sociopragmatic approach
چکیده زبان به عنوان یک وسیله در ایجاد و بازسازی سرمایه اجتماعی در چند دهه گذشته مورد توجه بوده است. اگر چه درباره سرمایه اجتماعی و سازه های مربوط به آن زیاد نوشته شده است ولی خیلی کم بر روی اینکه چطور زبان می تواند باعث ایجاد اعتماد یا بی اعتمادی بشود مطالعه ای انجام شده است. این مطالعه به منظور تحقق دو هدف انجام گرفته است. اول تلاش خواهد شد تا یک گونه شناسی از واژگانی که مردم کرد زبان شهر ا...
