Response of Marine‐Terminating Glaciers to Forcing: Time Scales, Sensitivities, Instabilities, and Stochastic Dynamics [PDF]

open access: yes, 2018
Recent observations indicate that many marine‐terminating glaciers in Greenland and Antarctica are currently retreating and thinning, potentially due to long‐term trends in climate forcing.

Simulation and Experimental Verification of Buried Pipeline Corrosion under the High-Voltage Direct Current Interference

open access: yesInternational Journal of Electrochemical Science, 2021
Aimed at the corrosion caused by the ground current of the high-voltage direct current (HVDC) transmission system to adjacent buried pipelines, horizontal delamination is carried out according to different soil conductivities, and a field-circuit ...

Behavior-Based Early Language Development on a Humanoid Robot [PDF]

open access: yes, 2002
We are exploring the idea that early language acquisition could be better modelled on an artifcial creature by considering the pragmatic aspect of natural language and of its development in human infants.

Grounding System Adequacy of HV/MV Substations in Areas With Reduced Accessibility [PDF]

open access: yes, 2015
The adequacy of grounding systems has to be verified periodically in the operational time. With urban development and buildings growth adjacent to power systems as HV/MV substations, it is very rare to have area around with sufficient accessibility for ...

Fault line selection of power distribution system via improved bee colony algorithm based deep neural network

open access: yesEnergy Reports, 2022
A fault line selection approach on the basis of modified artificial bee colony optimization deep neural network (ACB-DNN) is presented to address the difficulties in choosing a fault line in electric current grounding systems for small electric currents.

Identification of Single-Phase Line Break Fault Direction Based on Local Voltage Information in Small Current Grounding System Considering the Impact of DG

open access: yesIEEE Access, 2023
Line break faults commonly occur in distribution networks and pose the risk of electric shocks to nearby individuals and animals. This study aims to address the challenge of identifying the direction of a line break fault.
