Streamflow forecasting has always been a challenging task for water resources engineers and managers and a major component of water resources system control. In this study, we explore the applicability of a Self Organizing Radial Basis (SORB) function to one-step ahead forecasting of daily streamflow. SORB uses a Gaussian Radial Basis Function architecture in conjunction with the Self-Organizin...

Background The current US Environmental Protection Agency (EPA) maximum contaminant level (MCL) for arsenic in public water systems (10 µg/L) took effect in 2006. Arsenic is not federally regulated in private wells. The impact of the 2006 MCL on arsenic exposure in the US, as confirmed through biomarkers, is presently unknown. We evaluated national trends in water arsenic exposure in the US, hy...

Web directories organize voluminous information into hierarchical structures, helping users to quickly locate relevant information and to support decision-making. The development of existing ontologies and Web directories either relies on expert participation that may not be available or uses automatic approaches that lack precision. As more users access the Web in their native languages, bette...

organizing lobar pneumonia is a rare form of bronchiolitis obliterans organizing pneumonia.  herein, we report a rare case of organizing pneumonia involving lung, mediastinum and esophagus.  a 16-year-old girl was referred to our center with clinical signs and symptoms of dysphagia and weight loss.  the main abnormal radiologic and endoscopic findings were stricture of the lower third of esopha...

integrated assessment of water resources systems, as one of the iwrm basic steps, is the most important stage in the process of planning and implementing water resources management. water accounting frameworks have been introduced for organizing water data and combining them with economic data to come up with effective strategies towards greater productivity with maintaining or improving enviro...

In the massive online worlds of social media, users frequently rely on organizing themselves around specific topics of interest to find and engage with like-minded people. However, navigating these massive worlds and finding topics of specific interest often proves difficult because the worlds are mostly organized haphazardly, leaving users to find relevant interests by word of mouth or using a...

OBJECTIVE This article presents a systematic framework characterizing adaptive systems. BACKGROUND Adaptive systems are those that can appropriately modify their behavior to fit the current context. This concept is appealing because it offers the possibility of creating computer assistants that behave like good human assistants who can provide what is needed without being asked. However, the ...

The results show that the varied appearance of the umbilical cord at birth can be related to its water content and that there are associated changes to be seen histologically in all layers of the cord, but especially in Wharton's jelly. Quantimet analysis confirms these findings and highlights a small group where dual pathology may exist. The relationship between oedematous cords, large drip vo...

Since the emergence of online auctions in 1995, many individuals have joined auction markets. Sometimes, many bidders have made wrong decisions (e.g., ‘‘Winner Curse’’) due to their limited knowledge and resources. Unfortunately, search engines only show a list of search results to users, and fail to provide further analysis that could help improve users’ decision-making. To solve this problem,...
