This paper presents a method to resize images by a rational factor of P/Q in the discrete cosine transform (DCT) domain where P and Q are relatively prime integers larger than one. Our method extends on the prior work of Mukherjee and Mitra which utilizes the spatial relationship of DCT coefficients between a block and its sub-blocks. To resize images by a factor of P/Q, the images are first up...

This paper gives a detailed analysis of the Cannon–Thurston maps associated to a general class of hyperbolic free group extensions. Let F denote a free groups of finite rank at least 3 and consider a convex cocompact subgroup Γ ≤ Out(F), i.e. one for which the orbit map from Γ into the free factor complex of F is a quasi-isometric embedding. The subgroup Γ determines an extension EΓ of F, and t...

ACKNOWLEDGEMENTS Acknowledgement sections are typically casually glossed over. Please don't do that now! Each name represents countless hours of active and behind-the-scenes support. And for each person mentioned, dozens of other people should have been mentioned as well. By tradition, students should be frustrated with their committee; I am not. At every stage they helped not hindered. I am gr...

| Most receiver designs for asynchronous Direct-Sequence Code-Division Multiple-Access systems exploit timing information to simultaneously detect the desired signal and suppress the interference. In this paper, a previously proposed MUSIC delay estimation algorithm is considered which requires no initial information and no exhaustive search of the delays. Based on a Taylor series expansion, ap...
