In this paper, we present a system for information retrieval of biomedical texts at passage level. Our system used KL-divergence as the underlying retrieval model. We further added query expansion and performed post-processing on the results. We were able to obtain a Document MAP of 0.3563, Passage MAP of 0.0464 and Aspect MAP of 0.2255 on one of the three runs.

Turbidity is a visual property of water that expresses the amount suspended substances in water. Its presence quantities more significant than permissible limit makes undrinkable and reduces effectiveness disinfectants treating pathogens. On this basis, turbidity used as basic indicator for measuring quality. This study aims to evaluate removal efficiency AL- Muthanna WTP. Water was parameter e...

Mobility depends essentially on investment, which often occurs in environments in which individuals match (school) or will match after investing (the labor market). Where partners can transfer surplus to each other only imperfectly (NTU), the pattern of matching will typically be inefficient, involving too much segregation, and provide a possible rationale for “associational redistribution” suc...

(2006). In search of query patterns: A case study of a university OPAC. Abstract A transaction log analysis of the Nanyang Technological University (NTU) OPAC was conducted to identify query and search failure patterns with the goal of identifying areas of improvement for the system. One semester's worth of OPAC transaction logs were obtained and from these, 641 991 queries were extracted and u...

Water turbidity and suspended sediment concentration (SSC) are commonly used as part of marine monitoring and water quality plans. Current management plans utilise threshold SSC values derived from mean-annual turbidity concentrations. Little published work documents typical ranges of turbidity for reefs within open coastal waters. Here, time-series turbidity measurements from 61 sites in the G...

The sustainable development of the water environment in Yangtze River basin has become a critical issue China. Turbidity is comprehensive element for quality monitoring. In this study, baseline turbidity was constructed using 36 years Landsat images from 1986 to 2021. spatial and temporal dynamics its driving factors were explored. results show that (i) proposed Landsat-based model performs wel...
