... and blockage to traffic. The wet season of 2018 was particularly severe and triggered many landslides that blocked roads for hours, and days in some cases. The cost of clearing these landslides amounted to an average of almost US$5000 per km. Because of the relatively low traffic volumes that use the mountain...

... among all possible pairs of dimensions. Skinny matrices are often of low rank; hence, applying a low-rank model does not improve data reconstruction. Consequently, square matrices provide the best data structure for low-rank models. In addition, this orientation coincides with the most cost efficient...

... aquifers. We argue that harvesting geothermal energy is economically feasible almost anywhere in the Netherlands with an alternative concept of low unit cost (LUC) installations. LUC produces at a limited rate from cleverly designed high-quality installations that can be developed at a considerably lower...

...Antonio Silva, M.EERI; Jose Miguel Castro; Ricardo Monteiro State-of-the-art seismic performance assessment of buildings requires a realistic estimation of the repair cost of structural and non-structural components. In this context, the US-based FEMA P-58 guidelines feature a procedure and repair...

.... These mostly rely on consequence functions derived by simulating the repair actions needed to restore a component to its pre-earthquake condition. However, due to the lack of data, only a few studies have benchmarked theoretical loss assessments with actual repair costs monitored in the aftermath of earthquake...

These types of geologic conditions are present in the Krishna-Godavari Basin, where a series of horst and grabens defined by deep-seated faults and persistent high sedimentation rates through geologic time, result in the development of challenging conditions for exploratory drilling.
