Background: Scoliosis is a health problem that causes a side-to-side curvature in the spine. The curvature may have an “S” or “C” shape. To evaluate scoliosis, the Cobb angle has been commonly used. However, digital image processing allows the Cobb angle to be obtained easily and quickly, several researchers have determined that Cobb angle contains high variations (errors) in the measurements. ...

We revisit the issue of memory effects, i.e. effects giving rise to a net cumulative change configuration test particles, using toy model describing emission radiation by compact source and focusing on scalar, hence non-radiative, part Riemann curvature. Motivated well known fact that gravitational is accompanied effect, permanent displacement relative separation present after has passed, we in...

Abstract The paper describes a method for optical measurement of oscillation blades in linear cascade designed flutter research. uses laser triangulation, which measures the distance between sensor and object. can be recalculated to angular displacement blade. However, relation is nonlinear due curvature dependence derived quantified analytically. further analyzes influence light refraction win...

Isolated mechanical systems—e.g., those floating in space, free-fall, or on a frictionless surface—are able to achieve net rotation by cyclically changing their shape, even if they have no angular momentum. Similarly, swimmers immersed “perfect fluids” are use cyclic shape changes both translate and rotate the swimmer-fluid system has linear Finally, systems fully constrained direct nonholonomi...

The understanding of the interactions between subduction-induced mantle flow and background (being global or regional) remains incomplete despite its potential impact on subduction dynamics associated deformation. Here we present results three-dimensional laboratory models zones at scale upper in which systematically vary plate's width trench perpendicular flow. In particular, test different ma...

we establish some relative volume comparison theorems for extremal volume forms of‎ ‎finsler manifolds under suitable curvature bounds‎. ‎as their applications‎, ‎we obtain some results on curvature and topology of finsler manifolds‎. ‎our results remove the usual assumption on s-curvature that is needed in the literature‎.

We describe a new method for computing a dense displacement eld from a time-sequence of 2D or 3D images. It consists in minimizing an energy deened on the space of correspondence functions. This energy is divided into two terms, one term which matches contour points and particularly high curvature points, and one regularization term which constrains the continuity of the eld. We introduce an ad...

This document lists some open problems related to the notion of discrete Ricci curvature defined in [Oll09, Oll07]. Do not hesitate to contact me for precisions. Please inform me if you seriously work on one of these problems, so that I don’t put a student on it! The problems are not ordered. Problem A (Log-concave measures). Ricci curvature is positive for RN equipped with a Gaussian measure, ...

Dynamic forces between a deformable tetradecane oil drop (radius of curvature z 25 mm) anchored on the cantilever of the Atomic Force Microscope (AFM) and similar oil drops (radii of curvature 80 to 500 mm) on the substrate in aqueous electrolyte with added sodium dodecyl sulfate surfactant have been studied. Measurements were made over a range of scan rates that span the range of Brownian velo...

OBJECTIVE To compare the safety and efficacy of patients undergoing dorsal penile plication with patients undergoing ventral and lateral plication. METHODS A retrospective review was performed of all patients who underwent penile plication between 2007 and 2013. Plication was performed through a 2-cm longitudinal incision in the proximal or midpenile shaft without degloving. Plication sutures...
