Modeling gap closure within vaporizing transmission lines of pulsed power machines using particle-in-cell direct simulation Monte Carlo (PIC-DSMC)
… numerical methods - Event Splitting (ES) and Dual Grids - was studied for modeling gap closure within an overall DSMC-PIC approach. Gap closure is a difficult computational problem due to massive gradients in density and electrostatic properties, extreme regime (relativistic electrons), and …

Improved geo-referencing and prescreening for detection of buried explosive hazards in forward-looking infrared imagery
… features in a cell-structured fashion from dual grids centered inside the detection window. The feature vectors are classified using a SVM. This detector is compared to an existing prescreening algorithm that uses an ensemble of local RX anomaly detection filters trained via genetic …
