More on the Terwilliger algebra of Johnson schemes
(Elsevier Science, 2014-08)
In Levstein and Maldonado (2007), the Terwilliger algebra of the Johnson scheme J(n,d) was determined when n≥3d. In this paper, we determine the Terwilliger algebra T for the remaining case 2d≤n<3d.
On Hilbert schemes and Chen-Ruan cohomology
A central scheme for advecting scalars by velocity fields obtained from Finite Volume multiphase incompressible solvers
(Elsevier Science Inc, 2016-08)
This paper presents an extension of the central scheme of Kurganov and Tadmor (2000) to work with solvers based on conservative face fluxes, which are usual in the solution of incompressible flows by the Finite Volume ...
Zuspan's Scheme Versus an Alternative Magnesium Sulfate Scheme: Randomized Clinical Trial of Magnesium Serum Concentrations
(Taylor & Francis Inc, 2010-01-01)
Objective. The purpose of this study was to determine whether magnesium serum concentrations in patients with severe preeclampsia or eclampsia treated with two different magnesium sulfate schemes were different. Methods. ...
Fully well-balanced, positive and simple approximate Riemann solver for shallow water equations
The present work is focused on the numerical approximation of the shallow water equations. When studying this problem, one faces at least two important issues, namely the ability of the scheme to preserve the positiveness ...
On Ponzi schemes in infinite horizon collateralized economies with default penalties
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2011-06-30)
Araujo, Páscoa and Torres-Martínez (2002) showed that, without imposing any debt constraint, Ponzi schemes are ruled out in infinite horizon economies with limited commitment when collateral is the only mechanism that ...
