Multiple Representations And Epistemic Games In Introductory Physics Exam Solutions, Adrienne L. Traxler, Jonathan V. Mahadeo, Daryl Mcpadden, Eric Brewe Jul 2014

Multiple Representations And Epistemic Games In Introductory Physics Exam Solutions, Adrienne L. Traxler, Jonathan V. Mahadeo, Daryl Mcpadden, Eric Brewe

Physics Faculty Publications

Previous analysis of common exam questions in introductory physics at Florida International University has revealed differences in the number and type of epistemic games played by students in their solutions. Separated by course format (lecture/lab, lecture/lab/recitation, or inquiry-based), student work also shows varying use of multiple representational tools. Here we examine representation use in more detail to establish a descriptive picture of representation use across multiple instructors and course formats. We then compare these profiles with the epistemic games played by students, asking whether the same epistemic game shows the same pattern of representational tools across course types. We find …

The Look-Locker Method In Magnetic Resonance Imaging: A Brief, Personal History, David C. Look Jan 2014

The Look-Locker Method In Magnetic Resonance Imaging: A Brief, Personal History, David C. Look

Physics Faculty Publications

The “Look-Locker” method of measuring nuclear spin-lattice relaxation times in a single sweep was invented by David C. Look and Donald R. Locker in 1970 and in the last twenty years has become widely used in magnetic resonance imaging. This article is a brief history of the invention from the remembrances of David Look.


Model Of Deep Nonvolcanic Tremor Part I: Ambient And Triggered Tremor, Naum I. Gershenzon, Gust Bambakidis Jan 2014

Model Of Deep Nonvolcanic Tremor Part I: Ambient And Triggered Tremor, Naum I. Gershenzon, Gust Bambakidis

Physics Faculty Publications

There is evidence of triggering of tremor by seismic waves emanating from distant large earthquakes. The frequency content of triggered and ambient tremor are largely identical, suggesting that tremor does not depend directly on the nature of the source. We show here that the model of plate dynamics developed earlier by us is an appropriate tool for describing the onset of tremor. In the framework of this model, tremor is an internal response of a fault to failure triggered by external disturbances. The model predicts generation of radiation in a frequency range defined by the fault parameters. Other specific features …


Influence Of Small Scale Heterogeneity On Co2 Trapping Processes In Deep Saline Aquifers, Naum I. Gershenzon, Mohamadreza Soltanian, Robert W. Ritzi, David F. Dominic Jan 2014

Influence Of Small Scale Heterogeneity On Co2 Trapping Processes In Deep Saline Aquifers, Naum I. Gershenzon, Mohamadreza Soltanian, Robert W. Ritzi, David F. Dominic

Physics Faculty Publications

The physical mechanism of CO2 trapping in porous media by capillary trapping (pore scale) incorporates a number of related processes, i.e. residual trapping, trapping due to hysteresis of the relative permeability, and trapping due to hysteresis of the capillary pressure. Additionally CO2 may be trapped in heterogeneous media due to difference in capillary pressure entry points for different materials (facies scale). The amount of CO2 trapped by these processes depends upon a complex system of non-linear and hysteretic relationships including how relative permeability and capillary pressure vary with brine and CO2 saturation, and upon the spatial …
