چکیده
Predicting where and when space weather events such as solar flares X-rays bursts are likely to occur in a specific area of interest constitutes significant challenge research. Space scientists are, therefore, gradually exploring multivariate data analysis techniques from the fields mining or machine learning order approximate future occurrences past distribution patterns. As emit extreme ultraviolet X-ray radiation, which leads ionization effect different layers ionosphere, most recent works related flare predictions using (ML) techniques, focused on time series predictions. Here, we suggest support vector for classifying subdaily diurnal total electron content (TEC) spatial changes prior events, assess possibility predicting B, C, M, X-class events. This is done opposed TEC ML techniques. The estimated up three days before each tested class along with skill scores precision, recall, Heidke score (HSS), accuracy, true statistics. results indicate that suggested approach has ability predict X M-class 24 h their occurrence 91% 76% HSS scores, respectively, improves over works. However, small-size C B-class flares, does not succeed producing similar promising results.

Solar flare signatures of the ionospheric GPS total electron content
6 [1] In this study, ionospheric solar flare effects on the total electron content (TEC) and 7 associated time rate of change (rTEC) derived from ground-based global positioning 8 system (GPS) receivers in the midday region are examined. The occurrence times and 9 locations of 11 solar flares are isolated from the 1–8 Å X-ray radiations of the 10 geosynchronous operational environmental satelli...

متن کاملIonospheric total electron content (TEC) studies with GPS in the equatorial region
This paper essentially deals with the effects of equatorial ionization anomaly gradient on space-based navigation systems like GPS. The equatorial region of the ionosphere, which extends about ±30dip about the magnetic equator, is characterized by a steep latitudinal gradient, not only in the maximum ionization but also in the total electron content (TEC), through a major part of the day. This ...

We introduce semi-supervised data classification algorithms based on total variation (TV), Reproducing Kernel Hilbert Space (RKHS), support vector machine (SVM), Cheeger cut, labeled and unlabeled data points. We design binary and multi-class semi-supervised classification algorithms. We compare the TV-based classification algorithms with the related Laplacian-based algorithms, and show that TV...
متن کاملUsing Wavelet Support Vector Machine for Fault Diagnosis of Gearboxes
Identifying fault categories, especially for compound faults, is a challenging task in mechanical fault diagnosis. For this task, this paper proposes a novel intelligent method based on wavelet packet transform (WPT) and multiple classifier fusion. An unexpected damage on the gearbox may break the whole transmission line down. It is therefore crucial for engineers and researchers to monitor the...
