We present a novel efficient algorithm for time-scale modification (TSM) of speech which gives output quality equal to that of a conventional TSM algorithm, but having computational load an order of magnitude less. The algorithm presented uses a fixed length rectangular stepping window and a simple peak alignment criterion to track the local natural scaling factor and adapt the window step size...

An integrated scaling factor of geometric functions into United Moment Invariant function is proposed for extracting feature of unconstrained words. Conventional regular moments have been proved that there were some drawbacks in the original in terms of scaling factor. Extracted features undergo discretization process before the classification task. In this paper, integrated scaling formulation...

Abstract Factor momentum produces robust average returns that exhibit a similar economic magnitude as stock price momentum. To the extent post-earnings announcement drift (PEAD) factor captures mispricing, winner factors earn profits from being long on underpriced stocks and short overpriced stocks. Conversely, loser-factors’ negative exposure to PEAD suggests loser capture mispricing by Option...
