Reza, H., Zhang, B., & Gupta, N. K. (2015). Assessment of efficiency of air abrasive cleaning on masonry stones and bricks using greyscale Imaging analysis. In Proc. of the Second Intl. Conf. on Advances in Civil, Structural and Construction Engineering

Advanced greyscale imaging analysis was conducted using Adobe Photoshop 6 on the surfaces of masonry stones and clay bricks, taken from old buildings, to accurately assess the efficiency of building cleaning. Five commonly used masonry stones and... Read More about Assessment of efficiency of air abrasive cleaning on masonry stones and bricks using greyscale Imaging analysis..

Inter-rater reliability in determining the types of vegetation on railway trackbeds (2015)
Presentation / Conference Contribution
Nyberg, R. G., Yella, S., Gupta, N. K., & Dougherty, M. (2015). Inter-rater reliability in determining the types of vegetation on railway trackbeds. In J. Wang, W. Cellary, D. Wang, H. Wang, S. Chen, T. Li, & Y. Zhang (Eds.), Web Information Systems Engin

Vegetation growing on railway trackbeds and embankments can present several potential problems. Consequently, such vegetation is controlled through various maintenance procedures. In order to investigate the extent of maintenance needed, one of the f... Read More about Inter-rater reliability in determining the types of vegetation on railway trackbeds.

Reliability of manual assessments in determining the types of vegetation on railway tracks (2015)
Presentation / Conference Contribution
Nyberg, R. G., Yella, S., Gupta, N. K., & Dougherty, M. (2015). Reliability of manual assessments in determining the types of vegetation on railway tracks. In J. Wang, W. Cellary, D. Wang, H. Wang, S. Chen, T. Li, & Y. Zhang (Eds.), Web Information System

Current day vegetation assessments within railway maintenance are (to a large extent) carried out manually. This study has investigated the reliability of such manual assessments by taking three non-domain experts into account. Thirty-five track imag...
