Dynamic behaviour of shredded rubber soil mixtures (2018)
Presentation / Conference Contribution
Bernal-Sanchez, J., McDougall, J., Barreto Gonzalez, D., Miranda, M., & Marinelli, A. (2018, June). Dynamic behaviour of shredded rubber soil mixtures. Presented at 16th European Conference on Earthquake Engineering, Thessaloniki

Residential buildings in high population density areas are seismically vulnerable to the action of major seismic events. The high cost and technical difficulties related to the use of advanced seismic isolations systems precludes its installation to...

Optical Fiber Sensor Design for Ground Slope Movement Monitoring for Railway Safety Operations (2018)
Presentation / Conference Contribution
Hook, D., Laing, W., Kerrouche, A., Barreto Gonzalez, D., & Alwis, L. S. (2018, October). Optical Fiber Sensor Design for Ground Slope Movement Monitoring for Railway Safety Operations. Presented at 17th IEEE SENSORS Conference, New Delhi, India

Scour and slope instability are a major issue in keeping the railway structures safe and operational. Conventional measurement techniques do not allow real-time monitoring of slope movement and/or are time/resource consuming. Novel fiber optic techno...
