Stepped spillways are designed to increase the rate of energy dissipation on the chute and to reduce the size of the downstream energy dissipator. It is essential to predict accurately the turbulent dissipation above the steps for large discharges per unit width corresponding to the skimming flow regime. New measurements were conducted in a large facility with a channel slope of 21.8o and a ste...

Pomelos (Citrus maxima) are known for their thick peel which-inter alia-serves as energy dissipator when fruits impact on the ground after being shed. It protects the fruit from splitting open and thus enables the contained seeds to stay germinable and to potentially be dispersed by animal vectors. The main part of the peel consists of a parenchymatous tissue that can be interpreted from a mate...

It is considered the mathematical model of a benchmark hydroelectric power plant containing water reservoir (lake), two conduits (the tunnel and turbine penstock), surge tank hydraulic turbine; all distributed (Darcy-Weisbach) local losses are neglected,the only energy dissipator remains throttling tank. Exponential stability would require asymptotic difference operator associated to model. How...

We present a detailed thermodynamic analysis of three-level quantum heat engine coupled continuously to hot and cold reservoirs. The system is driven by an oscillating external field described the Markovian master equation. use general form dissipator which consistent with thermodynamics. calculate heat, power, efficiency for heat-engine operating regime also examine uncertainty relation. stron...

Many studies have been carried out to determine the performance of energy dissipators proposed by different authors, mainly analyzing hysteretic loops loading and unloading. Likewise, authors sought simple, easy manufacture economical designs. Based on above, analysis a passive bidirectional dry friction dissipator system is presented, whose main characteristic implementation layer elements as ...

The severe sloshing induced by earthquake in cylindrical liquefied petroleum gas (LPG) storage tank is of great concern for liquid design. For suppressing sloshing, porous material attached to inner periphery the wall proposed and studied numerically using OpenFOAM. model was validated against with available data without ring baffle, flow through media a U-tube dam break. Fair agreements betwee...

Recent works on quantum resource theories of non-Gaussianity, which are based upon the type tools available in contemporary experimental settings, put Gaussian states and their convex combinations equal footing. Motivated by this, this article, we derive a new model dissipative time evolution unitary Lindblad operators which, while does not preserve set states, preserves combinations, i.e. so-c...
