Matt Smith with Robert BrownRF Challenges in High-Field MRIUsing the interaction of nuclear magnetic moments with applied magnetic fields, MRI (magnetic resonance imaging) represents the ability to capture powerful images of anatomical structures. To investigate dynamic processes, such as brain functioning, a more dynamic imaging method, fMRI (functional MRI),...
Justin Thrall with Dr. Christian Zorman (Electrical Engineering)Evaluation of MEMS-based Micromechanical ResonatorsResearch into the use MEMS technology in harsh environments has shown that current silicon-based MEMS devices are not as strong as desired. Silicon carbide based structures may have the strength to survive where ordinary silicon MEMS cannot. The...
Brian Tinker with Tanmay VachaspatiParticle Propagation in Astrophysical Magnetic FieldsThe influence of large scale astrophysical magnetic fields on cosmic ray propagation may aid in understanding the observed cosmic ray energy spectrum and arrival direction distribution. After learning some magnetohydrodynamics (MHD), and studying earlier work on cosmic ray propagation in...
Alyx Treat with Robert BrownOnce Again, With Feeling: Repetition Methods in Physics InstructionWe examine three newer methods of Physics education, all of which rely on the idea of repetition of concepts. Spiral Physics and Overview Case Study Physics (OCS) both start out with simple qualitative overviews of the subject,...
