Stability of Godunov’s method for a class of $2\times 2$ systems of conservation laws

L1 Stability for 2× 2 Systems of Hyperbolic Conservation Laws

We assume that the system is strictly hyperbolic, i.e. the matrix ∂f(u) ∂u has real and distinct eigenvalues λ1(u) < λ2(u) for all u under consideration, with the corresponding right eigenvectors ri(u), i = 1, 2. Each characteristic field is assumed to be either linearly degenerate or genuinely nonlinear [11], i.e. ri(u) · 5λi(u) ≡ 0 or ri(u) · 5λi(u) 6= 0, i = 1, 2. The purpose of this paper i...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Stability and Convergence of a Class of Finite Element Schemes for Hyperbolic Systems of Conservation Laws

We propose a class of finite element schemes for systems of hyperbolic conservation laws that are based on finite element discretizations of appropriate relaxation models. We consider both semidiscrete and fully discrete finite element schemes and show that the schemes are stable and, when the compensated compactness theory is applicable, do converge to a weak solution of the hyperbolic system....

Stability of systems of viscous conservation laws

a comparison of linguistic and pragmatic knowledge: a case of iranian learners of english

در این تحقیق دانش زبانشناسی و کاربردشناسی زبان آموزان ایرانی در سطح بالای متوسط مقایسه شد. 50 دانش آموز با سابقه آموزشی مشابه از شش آموزشگاه زبان مختلف در دو آزمون دانش زبانشناسی و آزمون دانش گفتار شناسی زبان انگلیسی شرکت کردند که سوالات هر دو تست توسط محقق تهیه شده بود. همچنین در این تحقیق کارایی کتابهای آموزشی زبان در فراهم آوردن درون داد کافی برای زبان آموزان ایرانی به عنوان هدف جانبی تحقیق ...
