Accurate evaluation of combustion enthalpy by ab-intio computations [PDF]

open access: yesScientific Reports, 2022
Accurate evaluation of combustion enthalpy is of high scientific and industrial importance. Although ab-initio computation of the heat of reactions is one of the promising and well-established approaches in computational chemistry, reliable and precise ...

Accurate Computations with Block Checkerboard Pattern Matrices [PDF]

open access: yesMathematics
In this work, block checkerboard sign pattern matrices are introduced and analyzed. They satisfy the generalized Perron–Frobenius theorem. We study the case related to total positive matrices in order to guarantee bidiagonal decompositions and some ...

Structured matrix methods for computations on Bernstein basis polynomials [PDF]

open access: yes, 2013
This thesis considers structure preserving matrix methods for computations on Bernstein polynomials whose coefficients are corrupted by noise. The ill-posed operations of greatest common divisor computations and polynomial division are considered, and it

Accurate Computations on Inertial Manifolds [PDF]

open access: yesSIAM Journal on Scientific Computing, 2001
Summary: An algorithm is implemented for the computation of inertial manifolds to arbitrary accuracy. It is applied to the Kuramoto-Sivashinsky equation to recover the high wave number components of elements on the global attractor. The computational results demonstrate that this algorithm is significantly more accurate than previous methods when ...

On the Total Positivity and Accurate Computations of r-Bell Polynomial Bases

open access: yesAxioms, 2023
A new class of matrices defined in terms of r-Stirling numbers is introduced. These r-Stirling matrices are totally positive and determine the linear transformation between monomial and r-Bell polynomial bases.

On the Category of Petri Net Computations [PDF]

open access: yes, 1995
We introduce the notion of strongly concatenable process as a refinement of concatenable processes [DMM89] which can be expressed axiomatically via a functor $Q[-]$ from the category of Petri nets to an appropriate category of symmetric strict monoidal ...

High resolution methods for incompressible, compressible and variable density flows.

open access: yes, 2004
The uid dynamics community has dealt with a number of numerical challenges since the 1950's. These include the development of numerical methods for hyperbolic conservation laws with particular interest in capturing shock wave propagation and related ...

Second-Order Time-Accurate ALE Schemes for Flow Computations with Moving and Topologically Changing Grids

open access: yesFluids, 2023
In computations of unsteady flow problems by the arbitrary Lagrangian–Eulerian (ALE) method, the introduction of the grid velocity in the transport terms of the governing equations is not a sufficient condition for conservativeness if topology changes in
