In this paper, we prove the structural stability of transonic shocks for three-dimensional axisymmetric Euler system with swirl velocity under perturbations incoming supersonic flow, nozzle boundary, and exit pressure. Compared known results on shocks, one major difficulties flows swirls is that corner singularities near intersection point shock surface boundary artificial singularity axis appe...

The PAN spinning solution was chosen as the spiral research object. Laminar flow theory used to straighten and align macromolecules, needles were control twisting of straightened macromolecules. internal arrangement nanofibers became more compact helix number increased. TEM (transmission electron microscope) photograph motion trajectory TiO 2 (titanium dioxide) nanoparticles in nanofibers, whic...

Strabismus is one of the common vision disorders. For people with mild strabismus, many evidences showed that doing eye muscle exercise would be very helpful to straighten the weak eyes and improve eye performance eventually. In this paper, we propose aneye-trackingaided training system for strabismus therapy. We aim at helping strabismus people train eye muscle movements with a real-time train...

In this article, we briefly describe various tools and approaches that algebraic geometry has to offer to straighten bent objects. throughout this article we will consider a specific example of a bent or curved piece of paper which in our case acts very much like an elastica curve. We generalize this model to various shapes of paper which are stretched and bent and then finally implement it on ...

This paper addresses the problem of calibrating camera lens distortion, which can be signi£cant in medium to wide angle lenses. While almost all existing nonmetric distortion calibration methods need user involvement in one form or another, we present an automatic approach based on the robust the-least-median-of-squares (LMedS) estimator. Our approach is thus less sensitive to erroneous input d...

When endovascular treatment is performed, angulation of the access route for a device can make the operative procedure difficult. We encountered a case in which we successfully completed thoracic endovascular aortic repair (TEVAR) in a patient with severely angulated aorta by applying 'double-wire technique'. The patient was an 80-year-old woman. An aneurysm with a 71-mm diameter was observed i...

The early clinical results are described of a real time, electromagnetic imaging system as an aid to colonoscopy. After gaining experience with the use of the system, one experienced endoscopist was randomised to perform consecutive colonoscopies either with (n = 29) or without (n = 26) the imager view. All procedures were recorded on computer disk and replayed for retrospective analysis. Total...

BACKGROUND: Early marriage is subject to the loss of crucial moments in adolescence. Therefore, current research focuses on how adolescents consider early marriage. AIM: This study aimed explore adolescents’ perspectives small islands regarding METHOD: In this case, perspective eight as an actor and non-actor influence society their was revealed using a phenomenological design. Domain analysis ...

<p class="abstract">Deviations and deformities of the bony nasal skeleton are amenable to osteotomies in longitudinal, transverse oblique planes. These interventions undertaken either intranasal or percutaneous, translocate osteo-cartilaginous segments as a single entity. The intermediate osteotomy is usually resorted to, three situations, namely; very broad nose with good height, deviate...
