The geology of the Darien province of eastern Panama is presented through a new geologic map and detailed biostratigraphic and paleobathymetric analysis of its Upper Cretaceous to upper Miocene sediments. The sequence of events inferred from the stratigraphie record includes the collision of the Panama arc (the southwestern margin of the Caribbean plate) and South American continent. Three tect...

[1] This work explores the control of fore-arc structure on segmentation of megathrust earthquake ruptures using coastal geomorphic markers. The Arauco-Nahuelbuta region at the south-central Chile margin constitutes an anomalous fore-arc sector in terms of topography, geology, and exhumation, located within the overlap between the Concepción and Valdivia megathrust segments. This boundary, howe...

Abstract According to the increasingly severe situation of electricity safety. Aiming at difficulty in extracting arc fault features low-voltage three-phase systems and inconspicuous phase distinction, a selection method based on improved LSTM-TCN neural network is proposed. Firstly, structure activation function Long Short-Term Memory Network (LSTM) Temporal Convolutional (TCN) are according e...

Due to load growth and various types within the service territory, utilities need enhance utilization of substations. In any case, towards coordinated substation design, transformers' most total capacity cannot be reduced just because there is a lack proper coordination between transmission distribution systems. The systems' stability safe operability must investigated in substation. critical i...

Abstract A large number of connecting wires and electrical contact points exist in photovoltaic power generation systems, which can easily cause the occurrence an arc fault. Failure to detect isolate faults time will result serious fire hazards. In document, a new approach fault monitoring positioning built on variational mode decomposition is presented for variety series DC systems. The freque...
