... at critical locations in metallic structures, which are heavily used in hostile manufacturing environments. This paper presents the study of design, fabrication, and characterization of integrated microring sensors. Various thin film optical materials were studied and single ring resonators were designed...

... of applying energy is desired. This paper investigates material property changes of various metals (aluminum, copper, iron, and titanium based alloys) in response to the flow of electricity. Theory involving electromigration and electroplasticity is examined and the implications thereof are analyzed...

...A. R. Ragab; S. N. Samy; Ch. A. R. Saleh In this work central bursting in drawing and extrusion of metals is investigated. The analysis is based on a modified stress distribution within the die zone due to Shield ( Shield, R. T., 1955, J. Mech. Phys. Solids, 3, pp. 246–258 ) together with Gurson...
