Background: Glacial Lake Outburst Floods (GLOFs) occur when the dam containing a glacial lake fails, releasing large volumes of water suddenly and causing catastrophic downstream flooding. Climate change is increasing the number and size of glacial lakes, heightening the risk of GLOFs. Curent monitoring and prediction methods can be improved with a...

ABSTRACT
This paper deals a detailed study, control and energy management of a solar vehicle Multisource Power Supply. A PVG is used as the principal energy source and the batteries are used as secondary/storage source. The use of this last source can reduce strongly the power stress imposed on the primary source. The power sources (PVG- battery) ...

The on-load tap changing (OLTC) regulators have been widely used in various industry. The main function of OLTC is to change the turns of transformer winding, so that the voltage variations are limited without interrupting the secondary current. In other word the voltage can be regulated with the changer without any supply interruption using ANN co...

The major obstacle for learning-based RF sensing is to obtain a high-quality large-scale annotated dataset. However, unlike visual datasets that can be easily annotated by human workers, RF signal is non-intuitive and non-interpretable, which causes the annotation of RF signals time-consuming and laborious. To resolve the rapacious appetite of anno...

Most State-Of-The-Art (SOTA) Neural Machine Translation (NMT) systems today achieve outstanding results based only on large parallel corpora. The large-scale parallel corpora for high-resource languages is easily obtainable. However, the translation quality of NMT for morphologically rich languages is still unsatisfactory, mainly because of the dat...

This letter proposes a novel soft-switched single-stage-isolated dc-ac converter topology from the industry point of view. The proposed converter requires a lesser number of MOSFETs compared to a widely studied cycloconverter-type (CCT)-isolated dc-ac converter topology. This converter provides lower duty cycle loss, better efficiency, and electrom...

Any distribution network is prone to faults, and intermittency in power availability creates loss for the supplier as well as user. Majorly, a supply line can be effected by conditions of overvoltage and overcurrent, also under-voltage condition. During the occurrence of any fault, the incident goes unreported for long duration. Manual reporting ca...
