International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Existence of solutions to the Riemann problem for a model of two-phase flows
Electronic Journal of Differential Equations, 2015 We study the existence of solutions of the Riemann problem for a model of two-phase flows. The model has the form of a nonconservative hyperbolic system of balance laws. Based on a phase decomposition approach, we obtain all the wave curves.

Nonlinear Riemann-Hilbert problem for bordered Riemann surfaces [PDF]
American Journal of Mathematics, 2004 Let Σ be a bordered Riemann surface with genus g and m boundary components. Let { γ z } z ∈∂Σ be a smooth family of smooth Jordan curves in [inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="01i" /] which all contain the point 0 in their interior.

A riemann-hilbert problem in a riemann surface [PDF]
Acta Mathematica Scientia, 2011 Abstract One of the inspirations behind Peter Lax's interest in dispersive integrable systems, as the small dispersion parameter goes to zero, comes from systems of ODEs discretizing 1-dimensional compressible gas dynamics [17]. For example, an understanding of the asymptotic behavior of the Toda lattice in different regimes has been able to shed ...

British Journal of Clinical Psychology, EarlyView.Abstract Objectives There is a high, unmet sleep need in young people with mental health difficulties. We took a whole‐system approach to improving access to sleep support across a youth mental health system (14–25 years). Methods We used the Exploration, Preparation, Implementation and Sustainment (EPIS) framework to develop an implementation ...

Electronic Journal of Differential Equations, 2013 In the first part of this article, we study a discontinuous Riemann-Hilbert problem for nonlinear uniformly elliptic complex equations of first order in multiply connected domains. First we show its well-posedness. Then we give the representation of

On Riemann method for solving a mixed problem
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 The formula for solution of a problem for an equation with the higher partial derivative of the general type is constructed using Riemann method. In this problem the solution is found in the characteristic parallelepiped with separated by the non ...
