The morphological evolution of a carbonate fault line scarp from southern Italy, generated by transpressional faulting and evolved by slope replacement, has been reconstructed. C dating of faulted slope deposits (ages included between 18 ka and ~8 ka BP) have been performed to constrain the Late Pleistocene — Holocene evolution of that scarp. Longto short-term denudation rates have been also ev...

We demonstrate algorithm-based fault tolerance for silent, transient data corruption in “black-box” preconditioners. We consider both additive Schwarz domain decomposition with an ILU(k) subdomain solver, and algebraic multigrid, both implemented in the Trilinos library. We evaluate faults that corrupt preconditioner results in both single and multiple MPI ranks. We then analyze how our approac...

Strike-slip faults may be traced along thousands of kilometers, e.g., the San Andreas Fault (USA) or the North Anatolian Fault (Turkey). A closer look at such continental-scale strike faults reveals localized complexities in fault geometry, associated with fault segmentation, secondary faults and a change of related hazards. The North Anatolian Fault displays such complexities nearby the mega c...

Runtime verification (RV) is a natural fit for ultra-critical systems, where correctness is imperative. In ultra-critical systems, even if the software is fault-free, because of the inherent unreliability of commodity hardware and the adversity of operational environments, processing units (and their hosted software) are replicated, and fault-tolerant algorithms are used to compare the outputs....

The dramatic decrease in the cost of Global Positioning System (GPS) receivers has made feasible the establishment of extensive Continuous GPS receiver arrays (CGPS), for the study of crustal deformation (and to support differential GPS applications). The GPS Earth Observation NETwork (GEONET) of the Geographical Survey Institute in Japan and the Southern California Integrated GPS Network (SCIG...

The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements measured up to 10 m and strong ground motion velocity pulses exceed 100 cm/s. As there is no concrete method for the seismic design of near-fa...

In some subsurface urban development projects, bedrock faults intersecting with the tunnel path are inevitable. Due to high costs of it is necessary study behavior such concrete structures under fault movement risks. Using an advanced 3D numerical finite difference code and a plastic hardening constitutive model for soil, this paper examined performance straight oblique segmented Tabriz Subway ...

Duration of treatment is one of the main concerns of patients undergoing orthodontic treatment. Fixed orthodontic treatment lasts up to 2 to 3 years increasing the risk of external root resorption, periodontal problems and patient compliance [1]. Clinicians are constantly striving towards developing strategies to enhance the rate of orthodontic tooth movement. An increase in in-depth knowledge ...
