Islanding detection in distributed generators using GBDT-JS techniques

Science and Technology for Energy Transition, 2023
Renewable Energy Sources (RES) using PV arrays are considered and extensively employed in today’s world. Islanding is an issue that happens when The RES is connected to the grid and unexpected circuit breakers are connected to the grid trip.

Strong measurements give a better direct measurement of the quantum wave function [PDF]

, 2016
Weak measurements have thus far been considered instrumental in the so-called direct measurement of the quantum wavefunction [Nature (London) 474, 188 (2011)]. Here we show that direct measurement of the wavefunction can be obtained by using measurements

DWT/PCA face recognition using automatic coefficient selection [PDF]

, 2008
In PCA-based face recognition, there is often a trade-off between selecting the most relevant parts of a face image for recognition and not discarding information which may be useful.

Multiple distributed generators islanding detection using GBDT-JS techniques

Science and Technology for Energy Transition
Photovoltaic arrays and wind Distributed Generators (DG) have become integral to our renewable energy landscape. However, when a DG disconnects from the grid, the risk of islanding arises, necessitating detection within the stringent of two-second ...

A Study Concerning Soft Computing Approaches for Stock Price Forecasting

Axioms, 2019
Financial time-series are well known for their non-linearity and non-stationarity nature. The application of conventional econometric models in prediction can incur significant errors.

Hyperanalytic denoising [PDF]

, 2007
A new threshold rule for the estimation of a deterministic image immersed in noise is proposed. The full estimation procedure is based on a separable wavelet decomposition of the observed image, and the estimation is improved by introducing the new ...
