Manufacturing and repair tasks using additive subtractive laser processing (e.g., paint stripping drilling) are becoming widely used in ships, aircrafts, bridge structures. As with fire exhaust impingement, such low level heat fluxes (<10 W) could negatively impact mechanical properties of composite In this work, thermal excursions were simulated via continuous-wave exposure the center region a...

limit to the tension reinforcement ratio in flexural high strength reinforced concrete (hsrc) members isbased on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state.however, the provisions for the total amount of longitudinal reinforcement ratio ( and ) are not associated withany rational derivation. in this paper, a quantitative measure to e...

EDITOR: Extubation failure is defined as the need for reinstitution of ventilatory support within 24–72 h of planned endotracheal tube removal. It occurs in 2–25% of extubated patients. Many causes, such as an imbalance between respiratory muscle capacity and work of breathing, upper airway obstruction, excess respiratory secretions, inadequate cough, encephalopathy and cardiac dysfunction, hav...

There are profound analogies between fracture experiments and earthquakes; however, few works attempt a complete characterization of the parallels between these so separate phenomena. We have studied the acoustic emission (AE) events produced during the compression of porous SiO2 (Vycor). The distribution of avalanche energies (Gutenberg-Richter law), the rate of aftershocks (modified Omori’s l...

Several linear-time algorithms for automata-based pattern matching rely on failure transitions for efficient back-tracking. Like epsilon transitions, failure transition do not consume input symbols, but unlike them, they may only be taken when no other transition is applicable. At a semantic level, this conveniently models catch-all clauses and allows for compact language representation. This w...
