In this work we have compared two indexing algorithms that have been used to index and retrieve Carnatic music songs. We have compared a modified algorithm of the Dual ternary indexing algorithm for music indexing and retrieval with the multi-key hashing indexing algorithm proposed by us. The modification in the dual ternary algorithm was essential to(More)
This paper proposes a novel soft-switched dc-dc circuit to provide a zero-voltage transition at turn on for a conventional pulse width-modulated boost converter in a power factor correction (PFC) application. The proposed circuit enables a main switch of the dc-dc converter to turn on under a zero-voltage switching condition and simultaneously achieves both(More)
Nanotechnology is the application of science to control matter at the molecular level. A nanometer (nm) is one billionth of a meter, or roughly the length of three atoms side by side. A nanoparticle is a microscopic particle with atleast one dimension less than 100 nm. The applilcation of nanoscale materials and structures, usually ranging from 1 to 100(More)
