The current study investigates how young children allocate their attention in learning environments. Prior research has shown that elementary school students spend between 25% and 50% of instructional time off-task. However, the available research has not clearly identified the common sources of distraction, nor specified the relationship between the distraction source and learning outcomes. In...

The paper by A. Stotsky introduces an algorithm for real-time estimation of the engine friction torque, capable to achieve a dynamic adaptation of the static maps widely used in the engine control functionality. This adaptation of the friction map allows a better vehicle driveability performance and an enhanced control by the driver of the vehicle longitudinal transients. There are several inte...

Difficulty in interpreting and using spatial information from You-Are-Here maps (YAH maps specify a viewer’s location and orientation) stems from a misalignment between one’s physical orientation and the map’s orientation. The current research investigates the relationship between the participant’s physical location and orientation in accurately placing the location and orientation of another i...
