Analysis of Compressive Sensing and Hardware Implementation of Orthogonal Matching Pursuit

Description: My thesis is to understand the concept of compressive sensing algorithms. Compressive sensing will be a future alternate technique for the Nyquist rate, specific to some applications where sparsity property plays a major role. Software implementation of compressive sensing (CS) takes more time to reconstruct a signal from CS measurements, so we use the orthogonal matching pursuit and basis pursuit algorithms. We have used an image size of 256x256 is used for reconstruction and also implemented… more

Bilitis as Interpreted in Charles Koechlin's "Cinq chansons de Bilitis"

Description: Charles Koechlin (1867–1950) has been a notable figure in French music since the late nineteenth century. However, Koechlin's mélodies are not performed as often as the art songs of many other French composers. Koechlin's Cinq chansons de Bilitis is a collection of five songs based on Pierre Louÿs's Les chansons de Bilitis. The cycle was completed in 1898–1908. The stories of Bilitis are beautifully set by Koechlin, who uses his wide compositional facility. This dissertation serves as a guide t… more
