undergoing abdominal surgery. After animal use committee approval, 14 pigs were anaesthetized and the tracheas intubated with appropriately sized Hi-Lo Evac (n1⁄47) or TaperGuard Evac (n1⁄47) tracheal tubes. Saline based-fluid (pH 2.5/0.3 ml kg) stained with Methylene-Blue was instilled into the area below the vocal cords but above the inflated tracheal tube cuff via the Evac port. The cuff pre...

GENERATION by SHU ZHANG (Under the Direction of Khaled Rasheed) ABSTRACT In this thesis, two music accompaniment systems are presented. Evac (the evolutionary accompanist) is a system that engages in musical improvisation with the user. It uses a novel, implicitly interactive, genetic algorithm (GA), which allows the user’s actions to influence Evac’s musical performance without the need for ex...

It is a present-day challenge to design and develop oxygen-permeable solid oxide fuel cell (SOFC) electrode electrolyte materials that operate at low temperatures. Herein, by performing high-throughput density functional theory calculations, oxygen vacancy formation energy, Evac, data for pool of all-inorganic ABO3 AI0.5AII0.5BO3 cubic perovskites generated. Using Evac perovskites, the area-spe...

This research aims to prepare a nano composite material of ethylene vinyl acetate (EVAc) copolymer reinforced with both silica and silver (Ag+) nanoparticles different weight percentage ( 0.25, 0.5 & 1) wt.%. Spin coating technique was used for the preparation films SiO2 nanoparticles. Atomic force microscopy (AFM) measure roughness , in addition surface area ratio, valley fluid index bearing i...

This paper lists the recent developments in the FDS+Evac evacuation model. FDS+Evac is an agent based emergency egress simulation model which is embedded in the fire simulation program FDS, thus, enabling simultaneous simulation of the fire and egress processes. The main new feature of the evacuation module is better treatment of different behavioral types of the evacuees using herding type alg...
