Mapping between γ 5 schemes in the Standard Model Effective Field Theory

Journal of High Energy Physics
We explore the relation between two distinct prescriptions for γ 5 in dimensional regularization — the Breitenlohner Maison t’Hooft Veltman (BMHV) scheme and Naive Dimensional Regularisation (NDR).

GenSDF: An MPI-Fortran based signed-distance-field generator for computational fluid dynamics applications

SoftwareX
This paper presents a highly efficient signed-distance field (SDF) generator designed specifically for computational fluid dynamics (CFD) workflows. Our approach integrates the Message Passing Interface (MPI) for parallel computing with the performance ...

Numerical Computation of Unsteady Compressible Flow past a Plunging Aerofoil

Journal of Applied Fluid Mechanics, 2012
Unsteady Reynolds-averaged Navier-Stokes (RANS) computations are presented for subsonic and transonic flow past a plunging NACA 64A010 aerofoil. The Implicit RANS solver used for obtaining the time-accurate solution is based on finite volume nodal point ...

Accurate Sharp Interface Scheme for Multimaterials [PDF]

, 2012
We present a method to capture the evolution of a contact discontinuity separating two different material. A locally non-conservative scheme allows an accurate and stable simulation while the interface is kept sharp.

Towards Fast and Accurate Algorithms for Processing Fuzzy Data: Interval Computations Revisited [PDF]

, 2011
In many practical applications, we need to process data -- e.g., to predict the future values of different quantities based on their current values. Often, the only information that we have about the current values comes from experts, and is described in

Enhanced shifted Jacobi operational matrices of integrals: spectral algorithm for solving some types of ordinary and fractional differential equations

Boundary Value Problems
We provide here a novel approach for solving IVPs in ODEs and MTFDEs numerically by means of a class of MSJPs. Using the SCM, we build OMs for RIs and RLFI for MSJPs as part of our process.

Ship wake field analysis using a coupled BEMt-RANS approach

The prediction of a ship’s wake field and self-propulsion capabilities has traditionally been centered on experiments; however with the advancement in modern computing power, this can be achieved through the use of computational methods.
