Filtering-estimating the state of a partially ob­ servable Markov process from a sequence of observations-is one of the most widely stud­ ied problems in control theory, AI, and com­ putational statistics. Exact computation of the posterior distribution is generally intractable for large discrete systems and for nonlinear con­ tinuous systems, so a good deal of effort has gone into developing r...

Guided summarization is essentially an aspect-based multi-document summarization, where aspects can be taken as specified queries in summarization. We proposed a novel ranking algorithm, Decayed DivRank (DDRank) for guided summarization tasks of TAC2011. DDRank can address relevance, importance, diversity, and novelty simultaneously through a decayed vertex-reinforced random walk process in sen...

Background Historically, the prevalence of dental caries was higher in urban areas than rural areas of Thailand. This study aim to examine the time trends in caries status in children in Thailand. Material and Methods Linear regression was used to examine trend of dental caries prevalence and mean number of teeth with caries, filled and missing due to caries (dmft/DMFT) in urban and rural, of...

abstract in recent years, the old urban fabrics identification has become a challenging issue in urban planning society in iran. the insufficiency of triple indices which had been introduced by the high council on urban planning and architecture has been criticized by experts several times. in this paper we reconsider the existing urban fabrics identification method and introduce a suitable mod...

We found that decayed wood stakes with no termite damage collected from a termite-infested field exhibited a deterrent effect against the termite Reticulitermes speratus, Kolbe, 1885. The effect was observed to be lost or reduced by drying. After identification, it was found that the decayed stakes were infected by brown rot fungus Fibroporia radiculosa (Peck) Parmasto, 1968. In a no-choice fee...

This paper compares oral health status and presence of untreated, decayed permanent teeth in abused/neglected children with nonabused/non-neglected controls. The sample comprised 903 children between 5 and 13 years old; 30 were confirmed cases of child abuse and 873 served as controls. Their oral health status was assessed by two calibrated dentists using the DMFS index. Presence of untreated, ...
