The use of hierarchical Bayesian small area models, which take survey estimates along with auxiliary data as input to produce official statistics, has increased in recent years. Survey for domains are usually unreliable due sample sizes, and the corresponding sampling variances can also be imprecise unreliable. This affects performance model (i.e., will not an estimate or a low-quality modeled ...

This paper presents an ultra-low-power voice activity detection (VAD) system to discriminate speech from non-speech parts of audio signals. The proposed VAD uses level-crossing sampling for detection. useless samples in the signal are eliminated due activity-dependent nature this scheme. A 40 ms moving window with a 30 overlap is exploited as feature extraction block, within which output analog...
