The present numerical investigation focuses on the leading edge bluntness effects double-wedge with varied aft-wedge angles exposed to low enthalpy hypersonic free stream conditions. ratio in this study varies, ranging from R/L1 = 0 (sharp edge) 0.577 (maximum allowable bluntness), along angle varying between {\theta}2 450 and 600. Noticeably, even a small can completely change shock interactio...

BACKGROUND Varus deformity increases the risk of progression of medial compartment knee osteoarthritis. The aim of this study was to investigate the clinical and radiographic mid-term results of closing-wedge and opening-wedge high tibial osteotomy when used to treat this condition. METHODS From January 2001 to April 2004, ninety-two patients were randomized to receive either a closing-wedge ...

BACKGROUND Medial opening wedge distal tibial osteotomy, a relatively new technique for treatment of intermediate ankle joint arthritis, is a technically demanding procedure that requires preoperative planning to determine the size of the wedge that will restore anatomic alignment of the joint surface. The purpose of this study was to facilitate the preoperative planning process for distal tibi...

OBJECTIVE To review my experience in both malar reduction and mandibular reshaping techniques to establish optional, effective, and reliable surgical procedures. A square-shaped face is considered aesthetically unfavorable among East Asians; therefore, reduction malarplasty and mandibular reshaping are becoming more acceptable for aesthetic facial skeleton recontouring. METHODS The techniques...

We perform a Monte Carlo study of N-step self-avoiding walks, attached to the corner of an impenetrable wedge in two dimensions (d = 2), or the tip of an impenetrable cone in d = 3, of sizes ranging up to N = 10 steps. We find that the critical exponent γα, which determines the dependence of the number of available conformations on N for a cone/wedge with opening angle α, is in good agreement w...

Accretionary wedge earthquakes usually occur in the overriding crust close to trench or above cold nose of mantle wedge. However, mechanism and temperature properties related slab dip angle remain poorly understood. Based on 3D thermal models estimate subduction plate structure, we investigate distribution Alaska, which has a varying along trench. The horizontal distance wedge-earthquake hypoce...

Pressure-gain combustion has gained attention for airbreathing ramjet engine applications owing to its better thermodynamic efficiency and fuel consumption rate. In contrast with traditional detonation induced by a single wedge, the present study considers oblique shock interactions attached double wedges in hypersonic combustible flow. The temperature/pressure increases sharply across interact...

An ω-wedge consists of two rays emanating from a single 1 point (the apex), separated by an angle ω < π. Given a convex polygon 2 P , we place the ω-wedge such that P is inside the wedge and both rays 3 are tangent to P . The ω-cloud of P is the curve traced by the apex of 4 the ω-wedge as it rotates around P while maintaining tangency in both 5 rays. 6 Previous work crucially required knowledg...

ABSTRACT The addition of wedge-like fairings onto the side missiles and space launch vehicles, to shield devices such as cameras reaction jet nozzles, creates additional drag, particularly when in supersonic hypersonic freestream flow. An experimental computational study was performed obtain aerodynamic data on simple representative configurations test accuracy theories for drag increment due t...

The step-by-step preoperative planning for supracondylar opening wedge osteotomy of the femur for precise correction of the load axis of the lower limb using a fixed-angle implant (95° AO blade plate) is presented. The surgical technique and the use of a bone graft from the same site for filling in the defect are also presented.
