An analysis of delamination for a thin elastic film, attached to a substrate a corner, is carried out. The film is in compression and the analysis is performed by combining results from fracture mechanics and the theory of thin shells. The results show a very strong dependency of the angle of the corner. In contrast with earlier results for delamination on a flat substrate, the present problem ...

We propose a detection method and a removal filter for corner outliers in order to improve visual quality in highly compressed video. Corner outliers are detected using the direction of edge going through a block-corner and the properties of blocks around the block-corner. The proposed filter for removing corner outliers, which compensates the stair-shaped discontinuities around edges using the...

Free probability theory originated in the context of operator algebras, however, one of the main features of that theory is its connection with random matrices. Indeed, free probability can be considered as the theory providing concepts and notations, without relying on random matrices, for dealing with the limit N → ∞ of N ×N -random matrices. One of the basic approaches to free probability, o...

A convex corner models the upper surface of a deflected flap and shock-induced boundary layer separation occurs at transonic speeds. This study uses micro-vortex generators (MVGs) for flow control. An array MVGs (counter-rotating vane type, ramp type co-rotating type) with height 20% thickness incoming is installed upstream corner. The pressure distributions are similar regardless presence MVGs...

A novel numerical scheme has been developed to simulate high speed viscous flows in complex geometries using unstructured grids. A characteristic–filter based shock capturing scheme is applied as a corrector step to a non–dissipative predictor scheme. This algorithm is being used to study shock turbulent boundary layer interactions and this paper presents the results of a turbulent flow at Mach...

Most information received by the human is acquired through vision. However, image has the largest data amount in three information forms. If the image is not compressed, high transmission rate for digital image transmission and tremendous capacity for digital image storage can hinder the development of digital image. For example, for a color image whose resolution rate is 1280×1024, each pixel ...

Discontinuity detection plays an important role in image analysis applications like image registration, comparison, segmentation, time sequence analysis and object recognition. This paper presents a new approach for Corner Detection using First Order Difference Chain-Encoding. The proposed method is based on integer operations it is very simple and efficient. Preliminary results are presented a...

female patient, 54 years old, complained of excessive earing in the right eye for 12 years. After four years, he presented with progressive obstruction of the nasal assages. Approximately one year before presenting to his service, a bulging swelling, painful upon compression, ppeared near the inner corner of the right eye. On physial examination, she demonstrated epiphora in the right eye nd a ...

A flap can be used as a high-lift device, in which a downward deflection results in a gain in lift at a given geometric angle of attack. To characterize the aerodynamic performance of a deflected surface in compressible flows, the present study examines a naturally developed turbulent boundary layer past the convex and concave corners. This investigation involves the analysis of mean and fluctu...
