In this paper, we describe the the planning system SGPlan6 participating in the satisficing tracks of the deterministic part of the Sixth Planning Competition (IPC6). SGPlan6 is designed to solve both temporal and non-temporal planning problems specified in PDDL3 which may have soft goals, derived predicates or ADL features. SGPlan6 inherited the parallel decomposition framework from SGPlan5 wh...

Distinguishing subpopulations in group behavioral experiments can reveal the impact of differences in genetic, pharmacological and life-histories on social interactions and decision-making. Here we describe Fluorescence Behavioral Imaging (FBI), a toolkit that uses transgenic fluorescence to discriminate subpopulations, imaging hardware that simultaneously records behavior and fluorescence expr...

The master equation of a lattice gas reaction tracks the probability of visiting all spatial configurations. The large number of unique spatial configurations on a lattice renders master equation simulations infeasible for even small lattices. In this work, a reduced master equation is derived for the probability distribution of the coverages in the infinite diffusion limit. This derivation jus...

STScI has continued the development of systems for HST data calibration. The calibration database system (CDBS) tracks information about all HST calibration files. CDBS has been rebuilt to be more automated and provide some additional capabilities for users. We have also begun investigating the requirements for an on-the-fly calibration system. This system would allow users to retrieve data tha...

The localization accuracy of a track-before-detect search for a target moving across a distributed sensor field is examined in this paper. The localization accuracy of the search is defined in terms of the area of intersection of the spatial-temporal sensor coverage regions, as seen from the perspective of the target. The expected value and variance of this area are derived for sensors distribu...
