Intelligent systems in automobiles need to be aware of the driving and driver context. Available sensor data stream has to be modeled and monitored in order to do so. Currently there exist no building blocks for hierarchical modeling of driving. By semi-supervised segmentation such building blocks can be discovered. We call them drivemes in analogy to phonemes. More parsimonious modeling of dri...

This paper extends prior work in model-based verification and describes interface-driven analysis that combines textual requirement modeling to support automated test generation of Java test scripts for executing against a database. It describes concepts of models and test driver mappings using examples for testing security functionality of an Oracle database using Java and standard Structured ...

Few previous studies of driver situation awareness (SA) have focused on behavior in hazard negotiation. The objective of this research was to assess the effect of hazard exposure on driver SA and interactions with age and roadway complexity. Ten young (18–25 yrs) and ten older (65–81 yrs) participants drove in a simulator under two levels of environment complexity (simple – rural vs. complex – ...

PSPICE modeling of a commercial LED driver IC (TOP245P) and PC817A optocoupler is proposed for the switch-mode power supply (SMPS) (applicable to LED driver) design and simulation. An analog behavioral model of the TOP245P IC including the shunt regulator, undervoltage(UV) detection, over-voltage(OV) shut-down and SR flip-flop is developed by using PSPICE. The empirical equation of PC817A curre...

Emotional intelligence (EI) has received increasing attention in recent years as a driver of team effectiveness. However, research has yet to address EI in virtual teams (VT). The purpose of our study was to examine EI as a predictor of VT effectiveness. Further, we investigated quality of communication as a mediator of the EI-team viability relationship. We employed a work simulation using 228...

This paper presents our SmartCar testbed platform a real time data acquisition and playback system and a machine learning dynamical graphical models framework for modeling and recognizing driver maneuvers at a tactical level with particular focus on how contextual information a ects the driver s performance The SmartCar s perceptual input is multi modal four video signals capture the surroundin...
