DOI: 10.1109/tii.2020.3033170
Abstract: Crack detection on concrete bridges is a critical task to ensure bridge safety. However, many cracks on concrete bridges show low contrast and blurry edges in practice, which brings challenges to image-based crack detection. In… read more here.

DOI: 10.1155/2018/1537301
Abstract: Although the knowledge and technology of performance-based earthquake engineering have rapidly advanced in the past several decades, current seismic design codes simply ignore the effect of aftershocks on the performance of structures. Thus, the present… read more here.
