An Inquiry Into The Electro-Physiology Of Bacteria, Prasanth Prahladan Apr 2016

An Inquiry Into The Electro-Physiology Of Bacteria, Prasanth Prahladan

Electrical, Computer & Energy Engineering Graduate Theses & Dissertations

This thesis documents the exploration of tools and techniques which were used to determine the existence of patterns within and relationships between the voltage and calcium measurements from individual bacterial cells. The research lies in the broad domain of bacterial electro-physiology.


The Effects Of Weak Static And Pulsed Magnetic Fields On Fibroblast And Fibrosarcoma Cells Under A Controlled Magnetic Environment, Julian Brandon Cyrus Apr 2015

The Effects Of Weak Static And Pulsed Magnetic Fields On Fibroblast And Fibrosarcoma Cells Under A Controlled Magnetic Environment, Julian Brandon Cyrus

Electrical, Computer & Energy Engineering Graduate Theses & Dissertations

This thesis provides evidence supporting the claim that weak static and pulsed magnetic fields have measureable effects upon fibrosarcoma cells. Fibroblast and fibrosarcoma cell lines were exposed to 0, 100, and 200μT fields, with a static 45μT field as the control. Each exposure intensity, other than 0μT, was conducted at a 20 sec pulse repetition rate, as well as the normal static conditions. The cells were tested for variations in oxidative stress, membrane potential, and cell viability. The fibrosarcoma cells were also tested for cell count. The trials were conducted using an electromagnetic system that provided a controlled magnetic environment ...


Optimization And Control Of An Active Helmet Design For Head Injury Prevention, Chadi S. Abdel-Samad Apr 2015

Optimization And Control Of An Active Helmet Design For Head Injury Prevention, Chadi S. Abdel-Samad

Electrical, Computer & Energy Engineering Graduate Theses & Dissertations

Thousands of mild traumatic brain injuries (mBTIs) occur in US football each year. In some instances, injuries are quite serious and life-threatening. New NFL rules being enforced by the league are an attempt to address this problem. Of interest is whether an active helmet design, employing feedback, can also reduce the incidence of mBTIs in football. Medical evidence and research suggests that peak center of gravity (CG) head acceleration is well correlated with the onset and severity of mBTI. In this dissertation, an active helmet design is introduced, dynamically modeled, and explored from the perspective of using control to reduce ...
