The nonFickian flow of fluid in porous media is complicated by the history effect which characterizes various mixing length growth of the flow, which can be modeled by an integro-differential equation. This paper proposes two mixed finite element methods which are employed to discretize the parabolic integro-differential equation model. An optimal order(More)
With nonrelativistic QCD factorization, we present the first complete next-to-leading order study on the polarization of prompt J/ψ hadroproduction by including feeddown from χ(c)((3)P(J)(1),(3)S(1)(8)) and ψ(2s) which turn out to be very important parts. By using the color-octet long-distance matrix elements obtained from a combined fit of the measurements(More)
Based on the nonrelativistic QCD factorization scheme, we present the first complete next-to-leading-order study on the yield and polarization of Υ(1S,2S,3S) hadroproduction. By using the color-octet long-distance matrix elements obtained from fits of the experimental measurements on Υ yield and polarization at the Tevatron and LHC, our results can explain(More)
We calculate the next-to-leading-order (NLO) QCD corrections to e;{+}e;{-}-->J/psi gg via color singlet J/psi(3S1) at the B factories. The result shows that the cross section is enhanced to 0.373 pb by a K factor (NLO/LO) of about 1.21. By considering its dependence on the charm quark mass and renormalization scale, the NLO cross section can range from(More)
The FDC is a general-purpose program package for Feynman Diagram Calculation. We outline previous successes in calculations and focus on its recent progress about automatic deduction the Feynman rules for first principle model, especially for the supersymmetric model, proper evaluation of the rates of multi-final-particle processes and the event generators(More)
The Schwarz altemating algorithm [25, 21, 4, 27] is considered in this paper for mixed fimte element methodsfor second-order elhptic équations General convergence estimâtes similar to [4] are estabhshed In particular, we détermine a uniform convergence rate for the algorithm associated with a fine-coarse domain décomposition [17] Résumé — L'algorithme(More)
Most of the blind algorithms are based on one of the following properties: nongaussianity of the sources, their different autocorrelations, or their nonstationarity. Each of the methods is able to separate sources if the respective assumptions are met. But in reality, radar signals fulfill all of the three conditions at the same time. So we adopt the(More)
Computer assistance for breast conserving surgery requires a guidance method to assist a surgeon in locating tumor margin accurately. A wide array of guidance methods can be considered ranging from various pictorial representations, symbolic graphical interfaces as well as those based on other sensory cues such as sound. In this study, we present an(More)
