To develop an understanding of singularity formation in vortex sheets, we consider model equations that exhibit shared characteristics with the vortex sheet equation but are slightly easier to analyze. A model equation is obtained by replacing the ux term in Burgers' equation by alternatives that contain contributions depending globally on the solution. We… (More)

The overlapping sinc{collocation domain decomposition method combined with the Schwarz alternating technique is developed for two-point boundary-value problems for second-order ordinary diierential equations with singularities. The discrete system is formulated and the solution technique is described. It is shown that this method has an exponential… (More)

The sinc{collocation overlapping method is developed for two-point boundary-value problems for second-order ordinary diierential equations. The discrete system is formulated and the bordering algorithm used for the solution of this system is described. It is then shown that the convergence rate is exponential even if the solution has boundary singularities.… (More)

Here, we rigorously prove some of the results obtained with asymp-totic methods for a modiied Burgers' equation, obtained by replacing the ux term in Burgers' equation considered in its hyperbolic form by the Hilbert transform. We show that, under the asumptions ju x j 1 C ?1=3 , jH(u x)j 1 C ?1=3 , and R 1 0 jju x jj 2 dt C, H(u) being the Hilbert… (More)

We present an improved model for the vortex sheet equation, that combines some of the features of the models of Beale and Schaeeer, Dhanak, and Baker et al. We regularize the Beale-Schaeeer equation with a second-order viscous regularizing term, and we add a globally deened ux term in conservative form. We obtain u t + iu x = H(u)u ]x + ju x j 2 u x ]x + u… (More)

OBJECTIVE
The aim of this study was to improve the strength and quality of the titanium-hydroxyapatite interface in order to prevent long-term failure of the implanted devices originating from coating delamination and to test it in an in-vivo model.
METHODS
Ti disks and dental commercial implants were etched in Kroll solution. Thermochemical treatments of… (More)

Intracardiac echocardiography (ICE) is used in humans for percutaneous interventional procedures, such as transcatheter device closures. Intracardiac echocardiography provides high-resolution imaging of cardiac structures with two-dimensional, M-mode, Doppler, and also three-dimensional modalities. The present report describes application of ICE during… (More)
