Evolve Filter Stabilization Reduced-Order Model for Stochastic Burgers Equation
, 2018 In this paper, we introduce the evolve-then-filter (EF) regularization method for reduced order modeling of convection-dominated stochastic systems. The standard Galerkin projection reduced order model (G-ROM) yield numerical oscillations in a convection-

Bright Solvatochromic Fluorophores With Dual Emission Enabled by a Donor‐Engineering Strategy
Chemistry – A European Journal, EarlyView.We screened tertiary amines for installation on the donor unit of highly emissive donor–acceptor‐type solvatochromic fluorophores based on a 9,9‐dimethyl‐2‐phenyl‐9H‐fluorene scaffold, with the aim of enabling two bright emissive states to coexist. As a result, the azetidine derivative [4] and the azepane derivative [7] exhibited clear dual emission ...

Model Reduction of the Coupled Burgers Equation in Conservation Form
, 2011 This thesis is a numerical study of the coupled Burgers equation. The coupled Burgers equation is motivated by the Boussinesq equations that are often used to model the thermal-fluid dynamics of air in buildings.

On the existence of Burgers vortices for high Reynolds numbers
, 2009 Axisymmetric or non-axisymmetric Burgers vortices have been studied numerically as a model of concentrated vorticity fields. Recently it has been rigorously proved that non-axisymmetric Burgers vortices exist for all values of the vortex Reynolds number ...

Canadian Journal of Statistics, EarlyView.Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

VİSKOZ BURGERS DENKLEMİNİN KLASİK VE NÜMERİK ÇÖZÜMLERİ
, 2023 In this study, the viscous Burgers equation is studied both theoretically and numerically. Before introducing our model of interest, we provide a brief historical concept of the equation where we also remind the reader some basic concepts of the partial ...

Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

An Evolutionary Model with Interaction between Development and Adoption of New Technologies
We propose a difference-differential equation that reflects interactions between innovation and imitation processes to describe the evolution of the distribution curve of firms by efficiency levels.

The Effect of Electrolyte pH and Impurities on the Stability of Electrolytic Bicarbonate Conversion
ChemSusChem, Volume 18, Issue 6, March 15, 2025.The performance of bicarbonate electrolysis is largely controlled by the electrolyte inlet pH, the distance between the membrane and electrode, and the impurities present in the electrolyte. By complexing trace metal ions with ethylenediaminetetraacetic acid (EDTA), stability can significantly be improved and longer term operation can be achieved ...
