An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez
An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez
FIU Electronic Theses and Dissertations
Expertise in physics has been traditionally studied in cognitive science, where physics expertise is understood through the difference between novice and expert problem solving skills. The cognitive perspective of physics experts only create a partial model of physics expertise and does not take into account the development of physics experts in the natural context of research. This dissertation takes a social and cultural perspective of learning through apprenticeship to model the development of physics expertise of physics graduate students in a research group. I use a qualitative methodological approach of an ethnographic case study to observe and video record the …
Experimental And Numerical Analysis Of Coupling Between Musical Drumheads, Ben Boe
Experimental And Numerical Analysis Of Coupling Between Musical Drumheads, Ben Boe
Summer Research
The low frequency vibrations of two-headed musical drums are known to couple. However, little is known regarding the factors that determine the degree of coupling at higher frequencies. In this study the effects that depth, diameter and head tension have on the tendency of the drumheads to couple are investigated. Commercial finite element software was used to model a wide range of drums and to identify trends of coupling according to these factors. The numerical results were used to guide which parameters should be tested in the lab. Experimentally, two oppositely facing Electronic Speckle-Pattern Interferometry systems were used to optically …
