This article presents new data reduction methods based on the discrete wavelet transform to handle potentially large and complicated nonstationary data curves. The methods minimize objective functions to balance the trade-off between data reduction and modeling accuracy. Theoretic investigations provide the optimality of the methods and the large-sample distribution of a closed-form estimate of...

The ever increasing demand for electricity leads to the advancement of distributed generation (DG). Almost all DG sources are renewable nature. One major complications with high penetration is islanding. islanding may damage clients and their equipment. As per IEEE 1547 interconnection standards, will be identified in two seconds must turned off. In this paper, an advanced detection process sta...

We examine the affine Wigner distribution from a quantization perspective with an emphasis on underlying group structure. One of our main results expresses scalogram as (affine) convolution distributions. strive to unite literature distributions and we provide connection Mellin transform in rigorous manner. Moreover, present ambiguity function show how this can be used illuminate properties dis...

Smartphones, wearables, and Internet of Things (IoT) devices produce a wealth data that cannot be accumulated in centralized repository for learning supervised models due to privacy, bandwidth limitations, the prohibitive cost annotations. Federated provides compelling framework from decentralized data, but conventionally, it assumes availability labeled samples, whereas on-device are generally...

Background. Syngnathid fishes produce three kinds of sounds, named click, growl and purr. These sounds are generated by different mechanisms to give a consistent signal pattern or signature which is believed to play a role in intraspecific and interspecific communication. Commonly known sounds are produced when the fish feeds (click, purr) or is under duress (growl). While there are more acoust...
