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 ...

The widespread application of echocardiography to the field of congenital heart disease has led to the development of a concept of "echocardiographic discontinuity" for the diagnosis of some conditions. Although this is a valuable sign in differentiating such entities as tetralogy of Fallot, truncus arteriosus and double outlet right ventricle, the reported cases illustrate that the echocardiog...

When patients receive an intervention based on whether they score below or above some threshold value on a continuously measured random variable, the intervention will be randomly assigned for patients close to the threshold. the regression discontinuity design exploits this fact to estimate causal treatment effects. in spite of its recent proliferation in economics, the regression discontinuit...

An ionic current model of the retinal horizontal cell is constructed. The horizontal cell models are interconnected by gap junctions to form a horizontal cell layer. The light response properties of the L-type horizontal cell are analyzed using this model. We demonstrate the functional role of each ionic current and the role of the feedback loop between cones and horizontal cells. The present s...

This paper presents a treatment of first–order discontinuities (D1) that arise in discontinuitymeshes. An algorithm is described that, given a planar D1 discontinuity surface in a polyhedral scene, computes the corresponding discontinuity curves on the faces of the scene. A method is described to efficiently update the backprojection across a D1 discontinuity curve. An alternative update method...

The quality of the surrounding rock is crucial to stability underground caverns, thereby requiring an effective monitoring technology. Ground-penetrating radar (GPR) can reconstruct subterranean profile by electromagnetic waves, but two significant issues, called clutter and hyperbola tails, affect signal quality. We propose approach identify fractured rocks using 2D Wavelet transform (WT) F-K ...
