Abstract Vibration and noise aspects play a relevant role in the lifetime comfort of urban areas their residents. Among different sources, one coming from rail transit system will central concern following years due to its sustainability. Ground-borne vibration assessment as well techniques mitigate them become key elements environmental impact global enlargement planned for railway industry. T...

Space weather driven by solar activity can induce geomagnetic disturbances at the Earth's surface that can affect power transmission systems. Variations in the geomagnetic field result in geomagnetically induced currents that can enter the system through its grounding connections, saturate transformers and lead to system instability and possibly collapse. This study analyzes the impact of extre...
