Earthquakes are the result of slip along faults and are due to the decrease of rock frictional strength (dynamic weakening) with increasing slip and slip rate. Friction experiments simulating the abrupt accelerations (>>10 m/s(2)), slip rates (similar to 1 ...
This study introduces a novel algorithm to detect unexpected slipping-like perturbations based on the comparison between actual leg joint angles and those predicted by a pool of adaptive oscillators. The approach grounds on the hypothesis that during postu ...
Earthquakes occur because fault friction weakens with increasing slip and slip rates. Since the slipping zones of faults are often fluid-saturated, thermo-mechanical pressurization of pore fluids has been invoked as a mechanism responsible for frictional d ...
This work outlines two approaches for small unmanned aerial vehicles (UAVs) performing surveillance with fixed cameras. Small UAVs present significant control challenges, due to relatively low-bandwidth actuation and significant disturbances due to wind. T ...
The ability of nanosecond pulsed DBD actuators to control flow separation was investigated on a NACA 0015 profile for velocities reaching Re = 230,000 (24 m/s). The optimal location for the actuator was determined from oil flow experiments. Moderate voltag ...
Folded-plate structures provide an efficient design using thin laminated veneer lumber panels. Inspired by Japanese furniture joinery, the multiple tab-and-slot joint was developed for the multi-assembly of timber panels with non-parallel edges without adh ...
