In this study, nonlinear wave phenomena related to reections and transmissions of the phase-inversion-waves around the discontinuity of the system consisting of two parts of coupled van der Pol oscillators are investigated. Behavior of the phase-inversion-waves around a discontinuity in a coupled system consisting of two kinds of arrays of van der Pol oscillators classi ed into 8 types by compu...

Seismic velocity discontinuities are commonly found within the upper 100 km of the mantle lithosphere, with great variability in their depth, lateral extent, and the polarity of velocity jump. Among the more commonly observed is the ‘80 km’ or Hales discontinuity, identified in a variety of tectonic environments, and sometimes associated with seismic anisotropy. Teleseismic receiver functions f...

Knowledge management research needs consistent and empirically supported theory for sound foundations. Our research seeks to understand how to extend established organization theory and emerging knowledge-flow theory to inform the design of organizations through development of empirical theory. Because knowledge flows enable workflows, and workflows drive performance, theory suggests the organi...

When modelling a chemical process, a modeller is usually required to handle a wide variations in time and/or length scales of its underlying differential equations by eliminating either the faster or slower dynamics. When compelled to deal with both and simultaneously simplify model structure, he/she is sometimes forced to make decisions that render the resulting model discontinuous. Discontinu...

We reveal that realistic fluids generate microscopic-level discontinu-ity constantly and the discontinuity spreads out with motion of particles rather rapidly and widely. These things cannot be treated by the standard kinetic equations, and thus the existing fluid theories, macroscopic ones and microscopic ones, need to be revised considerably. It has been unanimously believed that the followin...

Pelvic discontinuity represents a rare but challenging problem for orthopaedic surgeons. It is most commonly encountered during revision total hip replacement, but can also result from an iatrogentic acetabular fracture during hip replacement. The general principles in management of pelvic discontinuity include restoration of the continuity between the ilium and the ischium, typically with some...

An extended isogeometric analysis (XIGA) approach is proposed for modeling fracturing in a fluid-saturated porous material. XIGA provides definition of the discontinuity independent underlying mesh layout, which obviates need knowing crack extension direction priori. Unlike Lagrange shape functions used standard finite element approach, non-uniform rational B-splines (NURBS) provide higher-orde...

A novel method for detecting altered fingerprints using scars, minutiae density and ridge discontinuity is proposed here.This paper mainly focuses on FFT enhancement for ridge discontinuity analysis and use of scars along with ridge discontinuity and minutiae density for alteration detection. The scar is detected by adaptive average filtering and thresholding. This method is found suitable for ...

Aortic-mitral valve discontinuity has previously been described in double outlet right ventricle, endocardial cushion defect, single ventricle, tetralogy of Fallot, and prolapse of the mitral valve. We are reporting two additional examples of aortic-mitral valve discontinuity including 15 cases of gross left ventricular dilation and a case of acute pneumococcal bacterial endocarditis with a la...

The theory of continuity based on the Lambek Calculus is well-de-veloped, but we need a compatible extension to include discontinuity.Earlier work set out ingredients: hypersequent calculus and proof netsexpanded with parameter edges. This paper completes a preliminaryline by finalising proof nets for basic discontinuity (that with one pointof discontinuity) and proving ...
