Does cognitive control affect successful "sandbagging" of concussion symptoms?
… effort. If an athlete fakes poor performance or “sandbags”, a future injury may go undetected. Therefore, the purpose of this study was to determine if the SportGait concussion baseline assessment detects differences between participants instructed to sandbag and those who are not. Furthermore, I …

Finite Element Analysis of Geotextile Tubes
The three-dimensional behavior of geotextile tubes is studied using finite element modeling. Two initial shapes are investigated, one with a flat length-to-width ratio of 2:1 and the other with a flat length-to-width ratio of 5:1. The tubes are modeled resting on elastic foundations. For each …
