In this paper, we propose a robust speech detection algorithm with Heteroscedastic Discriminant Analysis (HDA) applied to the Time-Frequency Energy (TFE). The TFE consists of the log energy in time domain, the log energy in the fixed band 2503500 Hz, and the log Mel-scale frequency bands energy. The bottom-up algorithm with automatic threshold adjustment is used for accurate word boundary detec...

Analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. In this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. The damage indices considered in this study are based...

Adversarial examples (AEs) bring increasing concern on the security of deep-learning-based synthetic aperture radar (SAR) target recognition systems. SAR AEs with perturbation constrained to vicinity have been recently in spotlight due physical realization prospects. However, current adversarial detection methods generally suffer severe performance degradation against region-constrained perturb...
