Spectral Mixture Modeling Using Principle Component Analysis, Joseph S. Makarewicz, Heather D. Makarewicz Apr 2018

Spectral Mixture Modeling Using Principle Component Analysis, Joseph S. Makarewicz, Heather D. Makarewicz

Scholar Week 2016 - present

A method for modeling mixtures between two end-member spectra using principle component analysis and linear regression was presented. The presentation included results from three binary mixture data sets including orthopyroxene-clinopyroxene, kaolinite-montmorillonite, and nontronite-ferrihydrite.


Design And Evaluation Of 3d-Printed Filar Micrometer, Emily Rull Apr 2018

Design And Evaluation Of 3d-Printed Filar Micrometer, Emily Rull

Scholar Week 2016 - present

This project sought to design and 3D-print a filar micrometer for double star measurements that amateur astronomers could produce cost effectively.

Double stars are celestial objects that allow the mass of stars to be calculated by assessing their orbits. Stellar mass affects every current model of stellar evolution, but the most accurate double star orbits can take decades to record. As a result of the long-term nature of such observations and lack of groundbreaking research in double star studies, professional astronomers are no longer focused on making these measurements. This allows amateur astronomers to pick up where professionals have left …


"Insufferably Stupid Or Miserably Out Of Place": F.A.P. Barnard And His Scientific Instrument Collection In The Antebellum South, Stephen Case Oct 2009

"Insufferably Stupid Or Miserably Out Of Place": F.A.P. Barnard And His Scientific Instrument Collection In The Antebellum South, Stephen Case

Faculty Scholarship – Geology

In the 1850s, the American scientist and educator Frederick A. P. Barnard created a collection of scientific apparatus at the University of Mississippi in Oxford, Mississippi, of a size and expense that surpassed any collection in the United States at that time. The collection, which would come to include over three hundred instruments of both American and European manufacture, was the attempt by Barnard, born and educated in the North, to bring Big Science to the South and challenge the dominance of Northern schools in science education. In this respect it failed, and the collection became a forgotten footnote in …
