We have been reporting our quenched staggered light hadron mass calculations for the past few years [1]. Our inverse squared coupling is set at β=6.5 corresponding to a high cutoff of a∼3.7 GeV. The lattice volume of 48 × 64 covers about 2.6 fm across for each space dimension and hence is comfortable enough even for our lightest pion with mπ∼0.06 a =220 MeV. We calculated staggered quark propag...

Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...

In this study, the 2D steady-state seepage analysis of dam body and its base is investigated using finite element method based on Galerkin’s approach. The foundation soil are considered as homogeneous isotropic anisotropic materials effects horizontal drainage length cutoff wall investigated. differential equation governing response water in obtained with help Darcy's law continuity equations. ...

We have considered the divergence structure in the brick-wall model for the statistical mechanical entropy of a quantum field in thermal equilibrium with a rotating BTZ black hole. Especially, the contribution to entropy from superradiant modes is carefully incorporated, leading to a very different result from known ones in the literature. That is, it is positive and also has a leading order di...

Abstract In this paper, the simulation–optimization method is used to study optimal location of cutoff walls for seawater intrusion. The optimization model based on minimizing chlorine concentration two water sources after 50 years. order reduce computational complexity, a Kriging surrogate simulation coupled with model. Finally, hypothetical case evaluate accuracy and performance results show ...

We discuss massive scalar perturbations of a Schwarzschild black hole. We argue that quantum effects alter the effective potential near the horizon resulting in Poincaré recurrences in Green functions. Results at the semi-classical level are independent of the details of the modification of the potential provided its minimum near the horizon is inversely proportional to the square of the Poinca...
