The Application Of Tomographic Reconstruction Techniques To Ill-Conditioned Inverse Problems In Atmospheric Science And Biomedical Imaging, Vern Philip Hart Ii
The Application Of Tomographic Reconstruction Techniques To Ill-Conditioned Inverse Problems In Atmospheric Science And Biomedical Imaging, Vern Philip Hart Ii
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Tomography is an imaging technique in which 3D models of objects are created from several 2D projections viewed at different angles. When the number of available projections is limited, the resulting data are said to be sparse. This restriction is often a direct result of the imaging geometry used to acquire the data. One-sided views and a small number of receivers can reduce the range of available projections, which makes the object more difficult to reconstruct. Approximate solutions to difficult imaging problems can be obtained using a class of iterative algorithms known as the algebraic reconstruction techniques (ARTs). The presented …
Confirmation And Investigation Of Higher Science Curiosity In Juarez Middle School Students Compared To Their Peers In El Paso, Texas, Karla Carmona Miranda
Confirmation And Investigation Of Higher Science Curiosity In Juarez Middle School Students Compared To Their Peers In El Paso, Texas, Karla Carmona Miranda
Open Access Theses & Dissertations
In the last 20 years attitudes towards science and science classes in K-12 education have been an important topic of investigation due to the decreasing number of students choosing Science, Technology, Engineering and Math (STEM) related careers, and the increasing need for STEM prepared workers to cover the job demands of the future. The purpose of this study is to confirm a previously measured difference in scientific curiosity between middle school students in El Paso and in Ciudad Juarez, and to collect additional data that might tell us what the possible factors or reasons for this difference are. Our sample …
Educational Looping And Retention In The Middle School Setting, Mary Elizabeth Feighery
Educational Looping And Retention In The Middle School Setting, Mary Elizabeth Feighery
LSU Master's Theses
Educational looping is an educational method where teachers remain with the same core group of students over multiple academic years. The current research on this topic shows a strong positive correlation between the effects of looping and the growth of personal relationships between students and teachers, but neglects to examine the connection between looping and student educational growth. This paper explores the relationship between looping and academic gains, as well as between looping and retention of content material over time. This paper explores both the relationship between looping and academic gains and between looping and retention of content material, and …
