The scope of this work is knowledge management in the Semantic Web. Its contribution is the design, development, and characterisation of an application node architecture for the Semantic Web, called Swan. The core of the Swan architecture consists of an OWL knowledge base which is supplemented by a hybrid reasoning mechanism. Hybrid reasoning in Swan combines F-Logic and Description Logic reaso...

mobility or traffic overload conditions. We use the term " soft " real-time services to indicate that real-time sessions could be regulated or dropped due to mobility or excessive traffic overloading at mobile wireless routers. SWAN is designed to limit such conditions, however. A novel aspect of SWAN is that it does not require the support of a QOS-capable MAC. Rather, soft real-time services ...

Sir, Double-cuffed Tenckhoff's catheters has been widely used for continuous ambulatory peritoneal dialysis (CAPD). Various techniques of insertion have been described with placement of catheter tip downwards into the pelvis for maximal drainage. One of the well-known complications of CAPD is migration of the catheter tip out of the pelvis which leads to inadequate drainage and dialysis. The in...

SWAN (Service for Web based ANalysis) is a platform to perform interactive data analysis in the cloud. SWAN allows users to write and run their data analyses with only a web browser, leveraging on the widely-adopted Jupyter notebook interface. The user code, executions and data live entirely in the cloud. SWAN makes it easier to produce and share results and scientific code, access scientific s...

Several of the fundamental theorems about algebraic K, and Kr are concerned with finding unimodular elements, that is, elements of a projective module which generate a free summand. In this paper we use the notion of a basic element (in the terminology of Swan [22]) to extend these theorems to the context of finitely generated modules. Our techniques allow a simplification and strengthening of ...

Last year Swan et al. (1) published a reanalysis of data from 61 studies originally compiled and analyzed by Carlsen et al. (2). Just prior to the appearance of the Swan et al. artide, we published a reanalysis in another journal (3). Regional differences were considered in both reanalyses, but we examined only the effect ofyear in the final models (fertility status was also considered in the i...

We apply the Hurst exponent idea for investigation of DJIA index time-series data. The behavior of the local Hurst exponent prior to drastic changes in financial series signal is analyzed. The optimal length of the time-window over which this exponent can be calculated in order to make some meaningful predictions is discussed. Our prediction hypothesis is verified with examples of '29 and '87 c...

Researchers have been researching for chance discovery more than 10 years. The aim of chance discovery is discover something, but chance discovery is rather different from data mining. In 2007 Taleb introduced a concept ``Black Swan.’’ Taleb uses this rare black swan metaphor to explain how general persons tend to ignore rare or novel events and the importance of being aware of such rare or nov...

BACKGROUND Rating scales are often used to identify children with potential Attention-Deficit/Hyperactivity Disorder (ADHD), yet there are frequently discrepancies between informants which may be moderated by child characteristics. The current study asked whether correspondence between parent and teacher ratings on the Strengths and Weakness of ADHD symptoms and Normal behaviour scale (SWAN) va...
