Abstract--The highly dynamic nature of infrastructureless adhoc networks poses new challenges during resource discovery. In this paper, we propose a novel algorithm for resource di...
Abstract--We prove that maximum-likelihood (ML) noncoherent sequence detection of orthogonal space-time block coded signals can always be performed in polynomial time with respect ...
Abstract. Content-based image retrieval (CBIR) with global features is notoriously noisy, especially for image queries with low percentages of relevant images in a collection. More...
