Abstract In 2002, the interferometric gravitational wave detector GEO 600 took part in a coincident science run (S1) with other detectors world-wide. When completed, GEO will employ a dual-recycling scheme which will allow its peak sensitivity to be tuned over a range of frequencies in the detection band. Still in the commissioning phase, GEO was operated as a power-recycled Michelson for the d...

This type of systems facilitates personalized, on-demand geospatial information or knowledge discovery and dissemination. The sys...

This paper describes statistical models and an efficient Monte-Carlo algorithm for detecting tracks of slowly moving objects in optical telescope imagery sequences. The algorithm is based on accurate robust image pre-registration with respect to the star background, hot/warm pixel suppression, extracting dense normalized local image features, pixelwise statistical event detection, segmentation ...

Service oriented architecture in a distributed computing environment, with loosely coupled geo-services is a new approach for using GIS services in environmental modeling. The messages exchanged must follow a set of standard protocols which support syntactic interoperability, but do not address application semantics. This article proposes a layer-based ontology with additional layers for descri...

Media mix modeling is a statistical analysis on historical data to measure the return on investment (ROI) on advertising and other marketing activities. Current practice usually utilizes data aggregated at a national level, which often suffers from small sample size and insufficient variation in the media spend. When sub-national data is available, we propose a geo-level Bayesian hierarchical m...

Heavy metal contamination of minesoils is a widespread problem in China. In Pingle manganese mineland in Guangxi (south China), heavy metal concentrations in soils and dominant plants were determined, and soil contamination was assessed with pollution index (Pi) and index of geoaccumulation (I-geo). Pi showed the minesoil was heavily polluted by Cd and slightly polluted by Cr. I-geo showed a se...
