In this paper, we present some of our recent experiences with a data visualization tool and offer some use cases where the visualization tool can potentially drive programmatic change in universities. The Ribbon Tool provides an interactive visualization of student flows through academic programs, progressing over time to either successful completion (graduation) or attrition. Through effective...

In this paper, effects of EHD actuators on hydrodynamic behavior and heat transfer of air flow over a circular cylinder were considered. Pressure and temperature distributions around the cylinder were measured in presence of wire-plate EHD actuators. The Reynolds number based on cylinder diameter (d) were 3500, 7000. Experiments were performed for various configurations. Based on obtained resul...

Several studies (e.g. Kerr, 1987; 1993; Diwadkar, Carpenter & Just, 2000) have asked participants to report the final location of a point after imaginary moves through 2D and 3D arrays. The results suggest that visualizing 3D space is inherently more difficult than 2D visualization, and may even use different brain mechanisms. However, 2D and 3D trials were presented in separate blocks, so part...

Despite technological advances in minimally invasive surgery (MIS) in recent years, 3D visualization of the operative field still remains one of greatest challenges. In this paper, the effect of three visualization techniques including conventional 2D, 2D with enhanced depth cue based on shadow, and active 3D displays for novices with no prior adaptation to laparoscopic visualization techniques...

in this research, the charged system search (css) and enhanced charged system search (ecss) algorithm are used to obtain the optimum design of irregular grillage systems with different spacing and various boundary conditions. the cross-sectional properties of the beams are selected as the design variables and the weight of structure is used as the objective function. the displacement limitation...
