Experimental results for single-bubble sonoluminescence of air bubbles at very low frequency f = 7.1 kHz are presented: In contrast to the predictions of a recent model [S. Hilgenfeldt and D. Lohse, Phys. Rev. Lett. 82, 1036 (1999)], the bubbles are only as bright (10(4)-10(5) photons per pulse) and the pulses as long (approximately 150 ps) as at f = 20 kHz. We can theoretically account for thi...

Peridynamics is a formulation of continuum mechanics based on integral equations. It is a nonlocal model, accounting for the effects of long-range forces. Correspondingly, classical molecular dynamics is also a nonlocal model. Peridynamics and molecular dynamics have similar discrete computational structures, as peridynamics computes the force on a particle by summing the forces from surroundin...

Construction projects using emerging bio-based materials have been realized over the past ten to fifteen years within Europe. Bio-based buildings utilize properties of natural regulate internal environments, particularly fluctuations in temperature and relative humidity. Despite individual exemplar demonstrating functional performance long-term operational cost savings, there hasn’t a prolifera...

Resilience is the capacity of any system to maintain its function, structure and identity despite disturbances. Assessing resilience has been elusive due high levels abstraction that are difficult empirically test, or lack quality data required once appropriate proxies identified. Most assessments limited specific situation arenas, making comparision one unresolved challenges. Here we show how ...
