Abstract
Conditions were determined for consistent coupling of a CO2 laser beam to weld 5182 aluminum
alloy sheet. Full penetration butt and bead-on-plate welds on 0.8 and 1.8 mm sheets were
performed. Process conditions examined included beam mode, spot size and irradiance,
shielding gas flow, and edge quality and fitup. The observed weld quality variations with the
different process parameters were consistent with physical phenomena and a threshold irradiance
model. Optimal conditions were determined for obtaining consistent wel ....etc

ABSTRACT:
Conventional closed die forging, is widely used for manufacture of superalloy parts. Despite recent technological advancements in the area of forging design, empirical and trial-and-error methods are still widely used in forging super alloy materials. This paper investigates the effect of flash thickness and various geometrical forging design parameters including internal and external drafts and internal and external corner radii, on the die cavity filling, forging load and raw material cost when forging Nimonic80-A a supera ....etc

Abstract:
superalloy, exhibits excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. Also called high-performance alloy, Superalloys typically have a matrix with an austenitic face-centered cubic crystal structure. A superalloy's base alloying element is usually nickel, cobalt, or nickel-iron. such materials allow the turbine to operate more efficiently by withstanding higher temperatures and Superalloy development has relied heavily on both chemical and ....etc

Abstract:
Transducers for high-power sonars, an important tool for undersea exploration and monitoring, may be required to work in deep water where pressures are higher than several tens of MPa. In contrast with the piezoelectric devices commonly used as high-power sonars for seabed resource exploration, electroactive polymers offer the benefits of high coupling efficiency, low cost, and the ability to form large area skins or other devices. One question about the use of electroactive polymers for sonar has been their ability to withsta ....etc

Role & Role Effectiveness
Role, Role Space & Role Set
• Mutual obligations under a social system
• Functions one performs in response to the expectations
• Role is defined with the expectations of the role senders, including those of the role occupant.
• Role Space is a dynamic relationship between the self and the various roles an individual occupies and also amongst these roles
• Role Set is a subsystem or inter relationships between a particular role and the other roles in an organi ....etc
