Abstract. We introduce a hierarchical Bayesian model for the spatial distribution of rainfall corresponding to an extreme event specified duration that could be used with regional hydrologic models perform risk analysis. An is defined if any gaging site in watershed experiences annual maximum and field at all sites occurrence modeled. Applications data from New York City demonstrate effectivene...

Every time we detect a part that is out of tolerance, the implication is that something went wrong in the machining process: either the operator made a mistake, or the machine tool did. A lot of the time, problems with the machine get blamed on the operator. Rather than expect the operator to compensate for every machine tool problem -at the expense of increased setup time and scrap -it makes m...

This paper presents a precise ( 1cm), lightweight (5kg) and low cost 3D laser range finder for the fast gaging ( 1 4 sec) of environments. Real-time algorithms for the data reduction, 3D-object segmentation are also presented. A special designed suspension unit, a standard servo motor and a standard 2D range finder are used to build the 3D scanner. Maximal resolutions e.g. 180 (h) 90 (v) degree...

High-magnitude, low-frequency discharges are more responsible for transporting suspended sediment and forming channels in northwestern California than in previously studied areas. Bankfull discharge and the magnitude and frequency of suspended sediment discharge were determined at five gaging stations in northwestern California. Although discharges below which 50 percent of the suspended sedime...

In previous work we have build a NIDS cluster as a scalable solution for realizing high-performance, stateful network intrusion detection on commodity hardware. Prototypes of our cluster, consisting of up to 10 PCs, are already operating at two major network sites. In this work we are now gaging the scalability of our approach on the DETER testbed to identify potential performance bottlenecks w...

--This paper presents the initial results of a research project concerning the mechanism of head injury. In order to begin to define the mechanism, it is necessary to determine mechanical properties of the various skull bones, organize them into constitutive equations, and develop a structural model of the skull. The material presented is concerned primarily with the development of experimental...
