An Analytical Method of Coulomb’s Active Earth Pressure Acting on Cohesion-Less Backfill Subject to Local Surcharge in Cold Regions

Advances in Civil Engineering, 2020
The traditional Coulomb’s earth pressure theory does not consider the effect of local surcharge on the lateral earth pressure and its critical failure angle.

Shock formation in the collapse of a vapor nano-bubble [PDF]

, 2014
In this paper a diffuse-interface model featuring phase change, transition to supercritical conditions, thermal conduction, compressibility effects and shock wave propagation is exploited to deal with the dynamics of a cavitation bubble. At variance with

Experimental study of visual corona under aeronautic pressure conditions using low-cost imaging sensors [PDF]

, 2020
Visual corona tests have been broadly applied for identifying the critical corona points of diverse high-voltage devices, although other approaches based on partial discharge or radio interference voltage measurements are also widely applied to detect ...

Bose-Einstein condensation in multilayers

, 2009
The critical BEC temperature $T_{c}$ of a non interacting boson gas in a layered structure like those of cuprate superconductors is shown to have a minimum $T_{c,m}$, at a characteristic separation between planes $a_{m}$.

Efficiency Enhancement Design Approach in the Side Wing of a FSAE Car Utilizing a Shutter-Like Fairing Structure

Applied Sciences, 2022
Aerodynamical design is one of the critical technologies in race car engineering, and favorable race car aerodynamics is supposed to provide sufficient negative lift force and keep the center of pressure in the vicinity of center of mass.

Nice inducing schemes and the thermodynamics of rational maps [PDF]

, 2010
We consider the thermodynamic formalism of a complex rational map $f$ of degree at least two, viewed as a dynamical system acting on the Riemann sphere.

A dynamic new look at the lambda transition [PDF]

, 2003
We discuss aspects of the theory of critical phenomena and explore the superfluid transition in 4He. We review some of the recent experimental and theoretical work on helium in nonequilibrium conditions and summarize some future space experiments that ...

Prediction of the Liquid Vapor Pressure Using the Artificial Neural Network-Group Contribution Method [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2015
In this paper, vapor pressure for pure compounds is estimated using the Artificial Neural Networks and a simple Group Contribution Method (ANN–GCM). For model comprehensiveness, materials were chosen from various families.
