Average corotation of line segments near a point and vortex identification

An easy-to-interpret kinematic quantity measuring the average corotation of material line segments near a point is introduced and applied to vortex identification. At a given point, the vector of average corotation of line segments is defined as the average of the instantaneous local rigid-body rotation over ‘all planar cross-sections’ passing through the examined point. The vortex identificati...

Regularizing a vortex sheet near a separation point

Current methods for computing vortex sheet separation use a regularization parameter which is discontinuous from the body to the vortex sheet. We propose two methods for reducing the errors associated with the discontinuity and improving convergence with respect to the regularization parameter. The ‘‘velocity smoothing” method is the simpler of the two, and removes the discontinuity in regulari...

Critical vortex line length near a zigzag of pinning centers

A vortex line passes through as many pinning centers as possible on its way from one extremety of the superconductor to the other at the expense of increasing its self-energy. In the framework of the Ginzburg-Landau theory we study the relative growth in length, with respect to the straight line, of a vortex near a zigzag of defects. The defects are insulating pinning spheres that form a three-...

Paramedic identification of electrocardiograph J-point and ST-segments.

INTRODUCTION Correct identification of the J-Point and ST-segment on an electrocardiograph (ECG) is an important clinical skill for paramedics working in acute healthcare settings. The skill of ECG analysis and interpretation is known to be challenging to learn and often is a difficult concept to teach. OBJECTIVES The objective of the study was to determine if undergraduate paramedic students...

Uniqueness for the Vortex-Wave System When the Vorticity Is Constant Near the Point Vortex

which means that ω is constant along the characteristics. In the general case of a vorticity ω ∈ L (R, L ∩ L(R)), these computations may be rigorously justified, so that the Eulerian formulation (1.1) and the Lagrangian one (1.2), (1.3) turn out to be equivalent. Since equation (1.1) governs the evolution of the vorticity ω, it is natural to express the velocity v in terms of ω. This can be don...
