Raman spectroscopy, and BET techniques. In vitro studies were performed in order to investigate the cellular attachment and proliferation of
osteoblasts on carbon surfaces. Results showed that cell proliferation is strongly dependent on crystallinity, orientation, surface roughness, and
BET surface area. Amine-based grafting molecules inhibited osteoblast proliferation. However, both oxygen and acid-based grafting molecules
promoted cell growth. This effect was more pronounced with longer grafting molecules. A Cellular Automata model was developed as a predictive
design tool.

Senior/Capstone Project
9:00 AM-12:00 PM
Kennedy Union Boll Theatre
This project represents the work of the graduating class from the Department of Civil and Environmental Engineering and Engineering Mechanics.
The class will be presenting conceptual and design work pertaining to land recently annexed by the City of Centerville from Sugarcreek Township
of what was formerly the property of the Dille family. The new development has been named Miami Valley Pointe by the students. The property
is located in Greene County, bounded to the north by Interstate 675, to the west by Wilmington Pike, and to the south and east by Clyo Road. The
work done by the 2012 Capstone Class includes site layout and design of an extension of Miami Valley Drive through the property, as well as an
acute care center and associated site development features. The presentation will last approximately three hours.

The memristor is known as the fourth fundamental two-terminal passive circuit element (the others being the resistor, capacitor, and inductor).
The memristor was first theorized by Dr. Leon Chua in 1971, and the first successful fabrication of the device was published by a research team
led by Dr. Stanley Williams at HP Labs in 2008. The memristor has unique properties including the ability change resistance based the amount
of charge flowing through the device, and more importantly the ability to retain its resistance state after the power is removed from the device.
These properties have led researchers to believe that this device can be used to approximate the effect of a synapse in neuromorphic computing
architectures. The synapse is a component of brain tissue that provides a connection with variable strength between neurons. Just as the memristor
can change its resistance state based on total charge through the device, the synapse has a variable connection strength based on the number
of neuron spikes that have been applied to another neuron through a given synapse. This presentation will discuss work completed thus far in
memristor device modeling and electronic circuit simulation and design. The memristor device model was developed so that circuit simulations
can be completed using a memristor model that can accurately match the IV characteristic of several published devices. Circuit designs have been
completed that show how memristor devices can be used as memory components in both neuromorphic and traditional computing systems. It
will also be demonstrated through simulation and electronic characterization how well the memristor can model a synapse.
