This paper reviews the basic ideas underlying one-dimensional uid dynamic models of coronal loops and presents some of their most recent applications. These models are an important theoretical support to explore the new scenario provided by the data of Yohkoh, SOHO and TRACE, and are useful to interpret observations, when supplemented by appropriate spectral synthesis codes. Possible developmen...

This paper presents a multi-resolution particle filter, applied to the recognition and localization of objects in an office environment, using a laser scanner. A fast low level particle filter combines multiple measurements of the Sick laser scanner to localize the legs of tables and chairs in an office environment. This low level filter uses a simple leg model to distinguish the legs from othe...

SPONSORS: FFM is jointly sponsored by the Intelligence Systems Support Office (ISSO) of OASD/C3I, the National Drug Intelligence Center (NDIC) and the Office of Research and Development (ORD). The prototype is being built and evaluated at the Federal Intelligent Document Understanding Laboratory (FIDUL) in Tyson's Comers, VA, in an unclassified environment which replicates the hardware and soft...
