Selective edge enhancement using anisotropic vortex filter

In optical image processing, selective edge enhancement is important when it is preferable to emphasize some edges of an object more than others. We propose a new method for selective edge enhancement of amplitude objects using the anisotropic vortex phase mask by introducing anisotropy in a conventional vortex mask with the help of the sine function. The anisotropy is capable of edge enhancement in the selective region and in the required direction by changing the power and offset angle, respectively, of the sine function.     

Emergence of Vibrio parahaemolyticus as an important cause of diarrhea in Malaysia

Vibrio parahaemolyticus was isolated from 47 of 2,699 stools examined primarily for the exclusion of cholera. All strains grew well in alkaline peptone water containing 0.5% NaCl and in Monsur's medium. Serotyping showed them to be of various types. Adults were mainly affected. The importance of looking for V. parahaemolyticus in clinical specimens from cases of diarrhea is emphasized.     

Tailored complex 3D vortex lattice structures by perturbed multiples of three-plane waves

As three-plane waves are the minimum number required for the formation of vortex-embedded lattice structures by plane wave interference, we present our experimental investigation on the formation of complex 3D photonic vortex lattice structures by a designed superposition of multiples of phase-engineered three-plane waves. The unfolding of the generated complex photonic lattice structures with higher order helical phase is realized by perturbing the superposition of a relatively phase-encoded, axially equidistant multiple of three noncoplanar plane waves. Through a programmable spatial light modulator assisted single step fabrication approach, the unfolded 3D vortex lattice structures are experimentally realized, well matched to our computer simulations. The formation of higher order intertwined helices embedded in these 3D spiraling vortex lattice structures by the superposition of the multiples of phase-engineered three-plane waves interference is also studied.     

Analysis and design of FRP externally-reinforced concrete beams against debonding-type failures

Epoxy-bonding of FRP plates to the tensile face of RC beams has been shown to be an effective repair and strengthening technique. However, local failure by debonding or ripping of concrete cover has been reported in experiments to be a likely mode of failure due to high interfacial shear and normal stress concentrations. Predictive models for finding the interfacial shear stress have been reviewed and evaluated using experimental data reported in the literature. The most critical parameters governing the interfacial shear strength and stress as determined by the models were also examined. Through understanding of the conditions that result in debonding failure, a better approach towards designing FRP-plated RC beams against this mode of failure might be achieved.

Résumé Le renforcement externe d'éléments en béton armé à l'aide de plaques synthétiques renforcées de fibres (FRP), s'est révélé être une technique efficace de réhabilitation des structures. Cependant, la rupture locale par décollement ou fissure du béton a été présentée dans des essais comme le mode de rupture le plus fréquent à cause de la forte concentration des contraintes de cisaillement et normales aux extrémités des plaques. Des modèles théoriques visant à trouver les contraintes de cisaillement ont été examinés et évalués en utilisant des données expérimentales rapportées dans la littérature. Les paramètres les plus critiques gouvernant la contrainte de cisaillement et la résistance au cisaillement de l'interface colle-béton, comme déterminé par les modèles théoriques, ont aussi été examinés. Pour comprendre les effets qui résultent de la rupture par décollement, une meilleure méthode de conception peut être réalisée afin d'éliminer ou de retarder ce mode de rupture.
