WANG, P. and KRAUS, N.C., 2005. Beach profile equilibrium and patterns of wave decay and energy dissipation across the surf zone elucidated in a large-scale laboratory experiment. Journal of Coastal Research, 21(3), 522–534. West Palm Beach (Florida), ISSN 0749-0208. The widely accepted assumption that the equilibrium beach profile in the surf zone corresponds with uniform waveenergy dissipatio...

Sustained molecular oscillations are ubiquitous in biology. The obtained oscillatory patterns provide vital functions as timekeepers, pacemakers and spacemarkers. Models based on control theory have been introduced to explain how specific oscillatory behaviors stem from protein interaction feedbacks, whereas the energy dissipation through the oscillating processes and its role in the regulatory...

Anomalous dissipation of energy in three dimensional turbulence is one of the basic statements of physical theory [55]. It has been verified experimentally to a large degree [75], but not mathematically. The statement is about the average behavior of the energy dissipation rate = ν〈|∇u|〉 as ν → 0. Here ν is kinematic viscosity, u is the velocity (assumed to have mean zero), ∇ are spatial gradie...

In the present study we explore material architectures that lead to enhanced dissipation properties by taking advantage of squirt-flow a local flow mechanism triggered by heterogeneities at the pore level. While squirt-flow is a known dominant source of dissipation and seismic attenuation in fluid saturated geological materials, we study its untapped potential to be incorporated in highly defor...

Kachanov’s simplifiedmodel ofmicrocrack interaction is applied to an investigationof the behaviour of a cracked body under predominantly compressive periodic loading, so that the cracks experience periods of closure and slip, with frictional dissipation. The model is shown to be equivalent to a discrete elastic frictional systemwith each crack representing one node. Theorems and algorithms from...

In this paper we investigate possible ways to improve the energy efficiency of a general purpose microprocessor. We show that the energy of a processor depends on its performance, so we chose the energy-delay product to compare different processors. To improve the energy-delay product we explore methods of reducing energy consumption that do not lead to performance loss (i.e., wasted energy), a...

When properly designed at ultra-low density, hollow metallic microlattices can fully recover from compressive strains in excess of 50%, while dissipating a considerable portion of the elastic strain energy. This article investigates the physical mechanisms responsible for energy loss upon compressive cycling, and attributes the most significant contribution to a unique form of structural dampin...

Jakubi, and Diego Pavón Departamento de F́ısica, Universidad de Buenos Aires, 1428 Buenos Aires, Argentina Departamento de F́ısica, Universidad Autónoma de Barcelona, 08193 Bellaterra, Spain Abstract In a recent paper we showed that a quintessence scalar field plus a dissipative matter fluid can drive late cosmic accelerated expansion and simultaneously solve the co...

Some properties of the annular billiard under the presence of weak dissipation are studied. We show, in a dissipative system, that the average energy of a particle acquires higher values than its average energy of the conservative case. The creation of attractors, associated with a chaotic dynamics in the conservative regime, both in appropriated regions of the phase space, constitute a generic...

Correlations for the prediction of biomass yields are valuable, and many proposals based on a number of parameters (Y(ATP), Y(Ave), eta(o), Y(c), Gibbs energy efficiencies, and enthalpy efficiencies) have been published. This article critically examines the properties of the proposed parameters with respect to the general applicability to chemotrophic growth systems, a clear relation to the Sec...
