The stability of steady, inviscid vortex pairs in equilibrium with a circular cylinder are studied by discretizing equations derived from contour dynamics. These flows were found previously using different methods in Elcrat, Fornberg, Horn & Miller (2000). There are two families of vortices, one with a pair of counter-rotating vortices standing behind the cylinder, which may be thought of as de...

We analyze the e!ect of inertia forces on damping induced during large shearing deformations of an isotropic, incompressible and homogeneous viscoelastic layer constrained between two rigid circular cylinders. The layer is deformed by holding the inner solid cylinder "xed and rotating the outer one by applying to it a time-harmonic axisymmetric tangential velocity. It is assumed that the layer ...

Originally developed by NASA as high performance piston alloys to meet U.S. automotive legislation requiring low exhaust emission, the novel NASA alloys now offer dramatic increase in tensile strength for many other applications at elevated temperatures from 450°F (232°C) to about 750°F (400°C). It is an ideal low cost material for cast automotive components such as pistons, cylinder heads, cyl...

In this paper, we propose novel elastic graph matching (EGM) algorithms for face recognition assisted by the availability of 3D facial geometry. More specifically, we conceptually extend the EGM algorithm in order to...

BACKGROUND The relationship between atrial electrogram (EGM) characteristics in atrial fibrillation (AF) and those in sinus rhythm (SR) are generally unknown. The activation rate and direction may affect EGM characteristics. We examined characteristics of left atrial (LA) EGMs obtained during pacing from different sites. METHODS The study included 10 patients undergoing pulmonary vein isolati...

BACKGROUND AND OBJECTIVES To investigate whether taste thresholds, as determined by electrogustometry (EGM) and chemical taste tests, differ by age and the severity of facial palsy in patients with Bell's palsy. SUBJECTS AND METHODS This study included 29 patients diagnosed with Bell's palsy between January 2014 and May 2015 in our hospital. Patients were assorted into age groups and by sever...

Nitric oxide (NO) is produced by NO synthase (NOS) from L-arginine (L-Arg). Alternatively, L-Arg can be metabolized by arginase to produce L-ornithine and urea. Arginase (AR) exists in two isoforms, ARI and ARII. We hypothesized that inhibiting AR with L-valine (L-Val) would increase NO production in bovine pulmonary arterial endothelial cells (bPAEC). bPAEC were grown to confluence in either r...

The entropy generation analysis of non-Newtonian fluid in rotational flow between two concentric cylinders is examined when the outer cylinder is fixed and the inner cylinder is revolved with a constant angular speed. The viscosity of non-Newtonian fluid is considered at the same time interdependent on temperature and shear rate. The Nahme law and Carreau equation are used to modeling dependenc...
