In the Tore Supra tokamak, the scrape-off layer profiles of discharges limited either on the inboard or on the outboard side are compared. Inboard-limited discharges are characterized by substantially longer SOL e-folding lengths of ion and electron temperatures and electron density measured near the top of the plasma, providing strong evidence that the ion and electron energy transport across ...

CONTEXT Although the introduction of a new method is generally hailed as a boon to contraceptive prevalence, uptake of new methods can reduce the use of existing methods. It is important to examine changing patterns of contraceptive use and method mix after the introduction of new methods. METHODS Demographic and Health Survey data from 13 countries were used to analyze changes in method use ...

An approach for assignment of the optimal location and tap changer adjustment related to flux-lock type superconducting fault current limiters with tap changer (TC-FLSFCL) is used in this paper by debating the reduction of fault current flowing from each device and enhancement of reliability varying with customer type in a distribution network connected with distribution generation (DG). TC-FLS...

The effective resolution of a numerical scheme describes the smallest spatial scale (largest wavenumber) that is completely resolved by that scheme. This is often significantly larger than the model’s grid spacing, resulting in poor representation of features that are of the order of the grid scale. We present two methods to determine the effective resolution of numerical advection schemes. An ...

The use of flux limiters is widespread within the scientific computing community to capture shock discontinuities and are paramount importance for temporal integration high-speed aerodynamics, multiphase flows hyperbolic equations in general. Meanwhile, breakthrough new architectures hybridization supercomputer systems pose a huge portability challenge, particularly legacy codes, since subrouti...

The abatement of particulate matter in gasoline direct injection (GDI) engines requires the use filters. In turn, optimisation their regeneration is based on a deep knowledge soot oxidation behaviour. determination intrinsic kinetic parameters GDI explored thermogravimetric analysis (TGA) and reaction rate modelling. New understanding provided enabling an accurate prediction wide range temperat...

In this paper we present the MmB schemes, which preserve the local maximum and minimum bounds of the initial data in the smallest union of mesh elements of previous time step containing the domain of dependence of the solution on the mesh element with center at point P under consideration. In 1-D, the MmB schemes are almost identical with TVD schemes. As well-known, there is no second-order TVD...

We present an elementary derivation of chaos control with simple limiters using the logistic map and the Henon map as examples. This derivation provides conditions for optimal stabilization of unstable periodic orbits of a chaotic attractor.
