Earthquake-induced ground failure, in the form of liquefaction or slope instability, manifests itself as permanent ground deformation (PGD), which can cause significant damage to buildings and infrastructure. Current methodologies for the evaluation of ground failure related earthquake losses are considerably less advanced than those for ground shaking. Most existing damage scales do not incorp...

on april 15, 1979,a destructive earthquake struck the southwestern part of yugoslavia, in which the total damage exceeded 2.7 billion dollars. in this paper, major engineering lessons learned in this earthquake are discussed and illustrated with representative photographs. the main causes of failure of masonary and reinforced concrete buildings are pointed out. effect of architectural design on...

The Music Information Retrieval Evaluation eXchange (MIREX) serves an essential function in the MIR community, but researchers have noted that the anonymity of its datasets, while useful, has made it difficult to interpret the successes and failures of the algorithms. We use the results of the 2012 MIREX Structural Segmentation task, which was accompanied by anonymous ground truth, to conduct a...

During an earthquake, significant damage can result due to instability of the soil in the area affected by internal seismic waves. A liquefaction-induced lateral ground displacement has been a very damaging type of ground failure during past strong earthquakes. In this study, neuro-fuzzy group method of data handling (NF-GMDH) is utilized for assessment of lateral displacement in both ground sl...

Covid-19 is a novel virus with high affinity to spread in the community. In December 2019, it was first identified in Wuhan, China. The symptoms are non-specific, so fever, cough, dyspnea, are prominent features. Respiratory failure and mortality have also been reported. The most common lung CT scan findings are bilateral ground glass opacities.
