The first derivative of the determinant function is given by the well-known Jacobi's formula. We obtain three different expressions for all higher order derivatives. Norms of these derivatives are then evaluated exactly.
Data warehousing technology has made a huge impact in the world of business; it helps to turn data into information that helps analysts to make strategic decisions. Currently most data warehouse approaches employ static refresh mechanisms. But for various business requirements this is not an appropriate solution.

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. This was necessary to synthesize information and enable Ananya's managers to visualize and interpret data… (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)
