The development of single-shot, high-dynamic-range temporal measurement devices has become necessary for characterizing high-energy petawatt laser pulses. Because of the low repetition rate of such systems, no device offers high-dynamic-range measurements in a single-shot mode. In addition, investigating the unexpected temporal behavior of pulses amplified by new techniques such as analyzed in ...

In this paper, we propose an improved speech/music discrimination method based on a feature combination and dimensionality reduction approach. To improve discrimination ability, we use a feature based on spectral duration analysis and employ the hierarchical dimensionality reduction (HDR) method to reduce the effect of correlated features. Through various kinds of experiments on speech and musi...

This paper presents a new coherency identification method for dynamic reduction of a power system. To achieve dynamic reduction, coherency-based equivalence techniques divide generators into groups according to coherency, and then aggregate them. In order to minimize the changes in the dynamic response of the reduced equivalent system, coherency identification of the generators should be clearl...
