How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
A method for assessing sudomotor function of a patient for evaluating diabetic and autonomous neuropathy is disclosed. The method is performed in a system comprising electrodes intended to be placed on different regions of the patient body, and an adjustable DC source. The method includes applying on the electrodes DC voltage pulses of varying volt...
Sudomotor dysfunction is a major clinical manifestation of diabetic autonomic neuropathy and is an early sign of prediabetes. SUDOSCAN™, a noninvasive and quick method was developed to assess sudomotor function based on measurement of the electrical current response of the skin when different rectangular pulses of low voltage amplitudes are applied...
This volume contains the proceedings of an international conference on Numerical Methods for Fluid Dynamics held at the University of Oxford in April 1995. Such conferences have been held at the Universities of Reading and Oxford since the early 1980s, under the auspices of the Institute for Computational Fluid Dynamics. The conferences have become...
This paper is concerned with the solution of the steady Euler equations by an implicit unsteady method of Lax-Wendroff type without artificial viscosity or upwinding. Stability and efficiency are discussed for various treatments of the implicit operator: direct solution, approximate factorization or a few iterations of a line-relaxation method. Com...
When solving the compressible Navier-Stokes equations, any method requires some numerical dissipation. This dissipation, internal in upwind and Lax-Wendroff-type centered schemes, and artificial in Runge-Kutta centered scheme, is necessary to avoid instability and spurious oscillations. However, this numerical dissipation should be significantly sm...
In this contribution to the Workshop on Hypersonic Flows for Reentry Problems, we are interested in showing that an implicit method without upwinding or flux limiter can calculate external flows at large Mach number, large angle of attack and large Reynolds number.
