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.

Tabulation of the Riemann problem solution in Godunov method for Soave – Redlich – Kwong equation of state [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThe work is devoted to the using of the exact solutions of the Riemann problem on the decay of an arbitrary discontinuity to describe the real gases flows with the Soave – Redlich – Kwong equation of state.

The generalized Riemann problem for reactive flows [PDF]
Journal of Computational Physics, 1989 A generalized Riemann problem is introduced for the equations of reactive non-viscous compressible flow in one space dimension. Initial data are assumed to be linearly distributed on both sides of a jump discontinuity. The resolution of the singularity is studied and the first-order variation (in time) of flow variables is given in exact form.

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

The Riemann-Hilbert problem and the generalized Neumann kernel [PDF]
, 2005 This paper presents two new Fredholm integral equations associated to the interior and the exterior Riemann-Hilbert problems in simply connected regions with smooth boundaries. The kernel of these integral equations is the generalized Neumann kernel. The

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

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 ...
