A New Device For Performing Simultaneous Sterno-Thoracic Cardiopulmonary Resuscitation (Sst-Cpr), Deepak S. Gupta

Theses and Dissertations

There are two different physiological mechanisms that cause blood to circulate around the human body during cardiopulmonary resuscitation. The "cardiac pump" generates blood flow by squeezing blood out of the heart as the sternum is depressed. The "thoracic pump" generates flow by forcing blood out of the heart and the great vessels as the intrathoracic pressure rises due to chest compression.

To date, all CPR techniques try to circulate blood during cardiac arrest by exploiting elite; the cardiac pump or the thoracic pump mechanism of blood flow. No mechanical CPR device thus far invented has tried to exploit both mechanisms …

Pelargonic Acid In Enhanced Oil Recovery, Hossein Noureddini, M L. Rempe

Papers in Biomaterials

Oxidation of monounsaturated iatty ac~dss,u ch as erucic and oleic acids, results in the for~nation of dibasic fatty acids, such as brassylic and azelaic acids. Dibasic acids find many inclustrial applications. Prlargon~ca cid is the co-product oi the process. Expanded use oi dibasic acids would require an expansion in the existing and possihiy new uses for pelargoriic acid and its derivatives. In this study, the potential for using pe!argonic acid in enhanced oil recovery is investigated. Experimental results are presented ior the enhanccd oil recover" by waterilooding with the aid oi a surfactan;. In sifu iormation of surfactant at the …

Effect Of Light Source On The Sorting Performance Of A Vision-Based Robot System, Johnny T. Li

Dissertations and Theses @ UNI

Industries look toward computer vision as a means to automate materials handling. To make this choice more appealing, useful and feasible vision applications must be explored. However, illuminance variation in the factory environment can undermine the capability and applicability of vision-based control systems. The purposes of this study were (a) to design and develop a vision-based robot material sorting system, (b) to determine the optimal settings for this system under fluorescent and incandescent lighting for two different color parts on a moving conveyor, and (c) to determine the sorting performance of this system under each light source.

The main components …
