This paper investigates problems concerning vegetation along railways and proposes automatic means of detecting ground vegetation. Digital images of railway embankments have been acquired and used for the purpose. The current work mainly proposes t... Read More about Detecting plants on railway embankment..

Machine vision approach for automating vegetation detection on railway tracks. (2013)
Journal Article
Yella, S., Nyberg, R., Payvar, B., Dougherty, M., & Gupta, N. K. (2013). Machine vision approach for automating vegetation detection on railway tracks. Journal of Intelligent Systems, 22, 179-196. https://doi.org/10.1515/jisys-2013-0017

The presence of vegetation on railway tracks (amongst other issues) threatens track safety and longevity. However, vegetation inspections in Sweden (and elsewhere in the world) are currently being carried out manually. Manually inspecting vegetation...

Condition monitoring of the strength and stability of civil structures using thick film ceramic sensors (2013)
Journal Article
Jabir, S. A. A., & Gupta, N. K. (2013). Condition monitoring of the strength and stability of civil structures using thick film ceramic sensors. Measurement : journal of the International Measurement Confederation, 46, 2223-2231. https://doi.org/10.1016/j.measurement.2013.03.018

Structural Health Monitoring (SHM) is about the mechanical strength and stability of a structure. The methods used to reveal and quantify the structure quality could be different in nature. Strain change is, however, the common structural parameter i... Read More about Condition monitoring of the strength and stability of civil structures using thick film ceramic sensors.
