A variant of the method of characteristics
Computer Assisted Methods in Engineering and Science, 2023 A variant of the method of characteristics for hyperbolic conservation laws is proposed in this paper. It is based on the time interpolation instead of space interpolation as in the standard method of characteristics.

On the Boundary Control of Systems of Conservation Laws
, 2001 The paper is concerned with the boundary controllability of entropy weak solutions to hyperbolic systems of conservation laws. We prove a general result on the asymptotic stabilization of a system near a constant state.

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Weak asymptotic solution for a non-strictly hyperbolic system of conservation laws-II
Electronic Journal of Differential Equations, 2016 In this article we introduce a concept of entropy weak asymptotic solution for a system of conservation laws and construct the same for a prolonged system of conservation laws which is highly non-strictly hyperbolic.

Shock Waves in Gas Dynamics [PDF]
Surveys in Mathematics and its Applications, 2007 Shock wave theory was studied in literature by many authors. This article presents a survey with references about various topics related to shock waves: Hyperbolic conservation laws, Well-posedness theory, Compactness theory, Shock and reaction-diffusion

Nonlinear Hyperbolic Conservation Laws. [PDF]
, 1987 Abstract : The focus of this research project has been the study of systems of conservation laws that lose strict hyperbolicity. Two areas of application, namely isentropic gas dynamics for a van der Waals gas, and multiphase flow in a porous medium were considered.

Business Strategy and the Environment, EarlyView.ABSTRACT This study systematizes the literature on eco‐innovation and economic complexity, aiming to understand how the sophistication of productive structures shapes countries' capacity to develop environmentally responsible innovations, and how eco‐innovation may, in turn, influence productive sophistication.

A new central-upwind scheme for solving the shallow water equations [PDF]
AUT Journal of Mathematics and ComputingWe have conducted a study where we applied one-dimensional central-upwind methods to estimate solutions of the Saint-Venant (SV) system. Our approach carefully considers the source terms associated with bottom topography.

Business Strategy and the Environment, EarlyView.ABSTRACT Although firms that integrate a sustainability orientation (SO) may experience a significant improvement in their resource efficiency, many, particularly small‐ and medium‐sized enterprises (SMEs), still struggle with the complexities of incorporating sustainability into their business models.

A Task-Driven Implementation of a Simple Numerical Solver for Hyperbolic Conservation Laws
ESAIM: Proceedings and Surveys, 2018 This article describes the implementation of an all-in-one numerical procedure within the runtime StarPU. In order to limit the complexity of the method, for the sake of clarity of the presentation of the non-classical task-driven programming environment,
