A relevant indicator for the eutrophication status in Baltic Sea is Chlorophyll-a concentration (Chl-a). Alas, ocean color remote sensing applications to estimate Chl-a this brackish basin, characterized by large gradients salinity and dissolved organic matter, are hampered its optical complexity atmospheric correction limits. This study presents retrieval improvements a fully reprocessed multi...

The question addressed in this paper is which types of spatial reference human users employ in the interaction with a robot and how a cognitively adequat model of these strategies can be implemented. Experiments in human-robot interaction were carried out which show how human users approach an artificial communication partner which was designed on the basis of empirical findings regarding spati...

This paper describes ongoing work on a system using spatial descriptions to construct abstract maps that can be used for goal-directed exploration in an unfamiliar office environment. Abstract maps contain membership, connectivity, and spatial layout information extracted from symbolic spatial information. In goal-directed exploration, the robot would then link this information with observed sy...

BACKGROUND Rhei Rhizoma (RR) has been widely used as laxative and processed to alter its therapeutic actions or reduce its side effects. In this study, we evaluated experimentally the clinical application guideline that RR should be alcohol-steamed seven times before being used in elderly patients, as described in Dongeuibogam, the most famous book on Korean traditional medicine. METHODS Unpr...

Over the last few years various scientific experiments and Grid projects have developed different catalogs for keeping track of their data files. Some projects use specialized file catalogs, others use distributed replica catalogs to reference files at different locations. Due to this diversity of catalogs, it is very hard to manage files across Grid projects, or to replace one catalog with ano...

RATIONALE, AIMS AND OBJECTIVES Rapid response systems (RRSs) are recommended by the Institute for Healthcare Improvement and implemented worldwide. Our study on the effects of an RRS showed a non-significant decrease in cardiac arrest and/or unexpected death from 0.5% to 0.25%. Unplanned intensive care unit (ICU) admissions increased significantly from 2.5% to 4.2% without a decrease in APACHE ...

This paper presents an application of spatial and ontology reasoning technologies for mobile robot tasks. We provide a combination of the spatial reasoning calculi RCC-8 and CDC as well as their integration with OWLbased ontologies. An architecture that combines inference tools like Prolog, description logic reasoners, and complex-event processing implements our approach. We illustrate the resu...

This contribution presents a corpus of spatial descriptions and describes the development of a human-driven spatial language robot system for their comprehension. The domain of application is an eldercare setting in which an assistive robot is asked to "fetch" an object for an elderly resident based on a natural language spatial description given by the resident. In Part One, we describe a corp...
