Fare policy analysis for public transport : a discrete-continuous modeling approach using panel data
… transport users to fare changes. A discrete-continuous framework is proposed in which ticket choice is modeled at the higher (discrete) level and frequencies of public transport use, based on mode and time-of-day, are modeled at the lower (continuous) level. This framework takes advantage of …

The Use of Stormwater Modeling for Design and Performance Evaluation of Best Management Practices at the Watershed Scale
… aspects of BMP design and to test the BMP modeling abilities of EPA SWMM 5.0. Simulations are performed using one-hour design storms and yearlong hourly rainfall traces. From these simulations, small water quality benefits are observed at the system level. This is seen as encouraging, given …

Contributions to the dynamics of helicopters with active rotor controls
… HHC structure used in this study, an approximate continuous modeling of the HHC system indicates that the closed loop, coupled helicopter-HHC system remains stable for optimal feedback control configurations which the more rigorous discrete analysis shows can result in closed loop instabilities. …

Design, Development, and Analysis of a Morphing Aircraft Model for Wind Tunnel Experimentation
… shape variations for fundamental research in modeling and control of morphing air vehicles. The vehicle is designed for five primary purposes: quasi-steady aerodynamic modeling of an aircraft with large planform changes, optimization studies in achieving efficient flight configurations, …

Gas-solid transport and reaction via intervened evaporating sprays
… onto free-fall particles. This feed-zone modeling, quantifying liquid feed trajectory, droplet vaporization, gas-solid transport and vapor cracking, is capable to provide hydrodynamic and pre-cracking inlet conditions for downstream gas-solid transport in the remaining part of riser. A …

Promising Practices: Teacher Perspectives on Successful Reading Strategies Evidenced in First Grade Bilingual Classrooms
… strategies that include guided reading, modeling, and read-alouds. Also, students’ interest in text content has been found to promote the development of connections between the text, their prior knowledge, and real-world experiences (Au, 2002). Purpose: The purpose of this study was to …

Modeling of non-uniform hydrodynamics and catalytic reaction in a solids-laden riser
… injection regime of the riser reactors. From the modeling point of view, to predict the reaction characteristics in riser reactors, there is a need to develop hydrodynamics model, which can predicts both axial and radial nonuniform distribution of hydrocarbon vapor and catalyst and back-mixing of …
