Marginal fractures of the medial tibial plateau have been reported in the literature as a secondary type of Segond fracture. Some reports described this entity in the setting of combined injuries such as root avulsions of the medial meniscus, complete disruption of the posterior cruciate ligament (PCL), partial tear of the anterior cruciate ligament (ACL), and tears of the medial meniscus and m...

We present a corner-detection algorithm based on a model for end-stopping cells in the visual cortex. Shortcomings of this model are overcome by a combination over several scales. The notion of an end-stopped cell and the resulting corner detector is generalized to color channels in a biologically plausible way. The resulting corner detection method yields good results in the presence of high f...

Chain code is an image representation which can be used to represent a shape of object or structure and also to represent connectivity between lines in the image boundary. It can be used in various applications because of its ability for information preservation and allows considerable storage space reduction for properties data image shape. This representation also can be applied in image proc...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

Harris corner detection algorithm called Harris corner detector is a very effective corner algorithm for gray-scale images. The corners extracted by Harris corner detector are stable, reliable, homogeneous and reasonable. However, it has own inevitable limitations. For the shape recognition of parts, an improved Harris corner detector is proposed in this paper. Based on the analysis of Harris c...

In this paper, a novel corner detection method is presented, to extract geometrically important corners for robot applications, such as indoor mobile robot navigation or manipulation. Intensity‐based corner detectors, such as the Harris corner, can detect corners in noisy environments, but have inaccurate corner positions and miss the corners of obtuse angles. Edge‐based corner det...

injuries to the posterolateral corner (plc) comprise a significant portion of knee ligament injuries. a high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. in this sense, stress radiographs can help to...

We construct various periodic travelling wave solutions of the Ostrovsky/HunterSaxton/short pulse equation and its KdV regularized version. For the regularized short pulse model with small Coriolis parameter, we describe a family of periodic travelling waves which are a perturbation of appropriate KdV solitary waves. We show that these waves are spectrally stable. For the short pulse model, we ...

This paper describes how the visual and acoustic characteristics of some Italian phones (/’a/, /b/, /v/) are modified in emotive speech by the expression of joy, surprise, sadness, disgust, anger, and fear. In this research we specifically analyze the interaction between labial configurations, peculiar to each emotion, and the articulatory lip movements of the Italian vowel /’a/ and consonants ...

We use the Reynolds-averaged Navier–Stokes (RANS) equations with a full Reynolds stress model (RSM) to study effect of corner angle in supersonic flow. RANS data are compared reference direct numerical simulation fully developed square duct flow, which support predictive capability secondary flows from Stress-ω RSM. then carry out parametric by changing range θ = 45 °– 135 °, focusing on mean s...
