AccES: A Framework for Predicting Building‐Level Loss of Accessibility to Essential Services Post‐Disasters Based on Publicly Available Information [PDF]
Risk AnalABSTRACT Natural hazards significantly disrupt access to essential services, affecting individuals' capacity to withstand and recover from such events. However, existing hazard resilience models often fail to account for the interdependencies among essential services and lack the spatial resolution needed to assess accessibility loss at the building ...

High Voltage, EarlyView.ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.
