Currently most data warehouse approaches employ static refresh mechanisms. But for various business requirements this is not an appropriate solution. Some critical data need to be refreshed in(More)
Chitin is a ubiquitous renewable biopolymer that is significantly distributed in the natural world. Biopolymeric nanoparticles (Nps) have been developed for various biomedical applications by researchers. Here, chitin derivative, dibutyrylchitin Nps (DBC) was synthesized as a nanocarrier for drug delivery using butyric anhydride and perchloric acid as a(More)
The objective of this paper is to propose a new methodology for text extraction and non text removal from colored images. Text in web pages, library documents etc. is one powerful source of high level semantics. Existing text extraction methods do not work efficiently in case of images with complex background, different contrast or text embedded in a(More)
There has been considerable work on matrix approximation problems in the space of matrices with Euclidean and unitarily invariant norms. We initiate the study of approximation problems in the space P of all n×n positive definite matrices with the Riemannian metric δ2. Our main theorem reduces the approximation problem in P to an approximation problem in the(More)
Real-time business intelligence (RTPI) is an approach to data analytics that enables business users to get up-to-the-minute data by directly accessing operational systems or feeding business transactions into a real-time data warehouse and business intelligence (BI) system. Business Intelligence (BI) technology has helped many organizations to make better(More)
The vast volume of complex, multidimensional data generated by the Bill & Melinda Gates Foundation's Ananya program to improve maternal, child, and integrated health in Bihar, India, compelled the program to develop a strong visual analytics system.
