Over the last century there has been a global interest in reducing/recycling waste material as well as creating energy from renewable and more eco-friendly sources. Catalytic gasification is one effective method that can promote low-temperature conversion of solid waste to energy, also referred to as “gasification”. The gas mixture produced by gasification of long-chain polymers using ruthenium (or platinum) catalysts consists of hydrogen, methane, carbon monoxide, carbon dioxide, and water. Product mixtures of gasification experiments were analyzed by Gas Chromatography (GC) and post-processed using statistical analysis. Using fundamental reactor design equations along with stoichiometric calculations yielded the percent gasified as …

Processing Conditions For Ultrastable Surfactant-Free Nanoparticle Stabilized Foams, Willian Ivancic, Richard Schmitt
Undergraduate Research Posters 2015
Foams, which are mixtures of gas and either a liquid or solid, are important to many applications, from consumer products to industrial processes. Stabilizing the liquid/gas interface against coalescence is key to the performance of foams. Typically, molecular surfactants (surface active agents) are used for interfacial stability, but adsorption/desorption of surfactant can diminish foam performance. We investigated the use of solid nanoparticles, rather than surfactants, as stabilizers. Fumed silica nanoparticles of varying surface chemistry, ranging from hydrophobic to hydrophilic, were suspended at 1% (w/w) and agitated in solutions of water and ethanol. Foam (gas in liquid), suspensions, and inverse foam …

Tuning The Size Of Elastin-Like Polypeptide Nanoparticles, Adam Maraschky
Undergraduate Research Posters 2015
The ability to control the size of biologically-based, environmentally-sensitive colloidal nanoparticles can advance their application in areas such as drug delivery, tissue engineering, and biosensors. Controlling size is a primary task in engineering nanomaterials because many of their properties depend on size. With the aim of fine- tuning the size of particles, we characterize mixtures of two elastin-like polypeptide structures: a linear and a trimer configuration. Both constructs undergo aggregation above their inverse transition temperatures, but the linear ELP forms large aggregates which coalesce into a protein-rich phase, while the ELP trimer with polar head groups forms stable polymer micelles …

Characterizing Stimuli-Responsive Materials For Drug Delivery: Interactions With Model Compounds And Ph Responsive Behavior, Ryan Martin, Eric Helm
Undergraduate Research Posters 2015
Stimuli responsive elastin-like polypeptide (ELP) nanoparticles are a promising platform for targeted drug delivery. Our laboratory has developed ELP nanoparticles that can specifically target cancer cells and provide contrast for MRI imaging. In order to utilize this system for drug delivery, the ability to carry and release drugs needs to be determined. Partition coefficients of drugs in ELP systems are one important measure of a system's ability to transport drugs, while a pH response mechanism can be utilized to provide selective drug release. In this study, we investigated the partition coefficients of seven model drug compounds in a pH responsive …

Effect Of Solidification Through Cross-Section Change On Dendritic Array In Single Crystal Castings, Christopher Stacey, Masood Ghods
Undergraduate Research Posters 2015
Dendritic single crystal turbine blades are the most critical component in a gas turbine engine. These are made by directional solidification in ceramic molds having many cross-section changes. Abrupt cross-section changes during casting are the source of casting defects, such as, freckles and spurious grains. Purpose of this study was to examine the role of convection associated with cross-section changes in producing microstructural defects. Al-7%Si alloy was directionally solidified at 11, 29 and 73 μm s-1 in graphite crucibles having abrupt cross-section decrease and cross-section increase to simulate solidification of turbine blades. It is observed that, (i) shrinkage flow leads …

Power Electronics Design For A Transfemoral Prosthesis, Taylor Barto
Undergraduate Research Posters 2015
Prosthetic legs do not always properly emulate a human leg. However, recent advances have allowed prostheses to include motors and brakes in order to closely mimic the performance of human legs. Unfortunately, motorized prostheses are often inefficient, which results in a dependence on batteries. This project aims to use energy regeneration methods to increase the operating time of motorized prostheses. Regeneration occurs when the leg requires braking; instead of using an energy-wasting braking mechanism, energy flows through an electronic circuit into a bank of supercapacitors. The energy can also flow in the reverse direction so that the motors can be …

Undergraduate Research Posters 2015
The computing power of current Graphical Processing Units (GPUs) has increased rapidly over the years. They offer much more computational power than recent CPUs by providing a vast number of simple, data parallel, multithreaded cores. In this project, we focused on the study of different variations of parallel selection algorithms on the current generation of NVIDIA GPUs. That is, given a massively large array of elements, we were interested in how we could use a GPU to efficiently select those elements that meet certain criteria and then store them into a target array for further processing. The optimization techniques used …

Learning To Drive A Simulator: Impact Of Prolonged Practice, Eyal Greenhouse, Samah Soki
Undergraduate Research Posters 2015
Most driving simulation experiments begin with a practice scenario, to allow participants to learn how to interact with the driving simulator. During practice, driving performance improves such that consistent steering and speed control is exhibited. It is unclear however, whether driver performance will degrade with prolonged practice, and whether the fidelity of the simulator contributes to this degradation. Therefore, a driving simulation experiment was conducted to examine the performance of drivers over one hour of driving, using two different simulators: DriveSafety RS-100 and RS- 600 models. The RS-100 is made up of a Logitech steering wheel and pedals attached to …

Prosthetic Socket Surface Initialization – For Future Use In Subject-Specific Socket Optimization, Brahm Powell
Undergraduate Research Posters 2015
For persons with lower limb amputations the human-prosthesis interface, termed the “prosthetic socket,” remains an area of ongoing research. Patient satisfaction is closely tied to the physical comfort of the device, which includes performance factors such as fit, moisture management, stiffness/rigidity, stress concentrations, range of motion, etc. An imbalance in these factors may result lack of mobility for the patient or worse, pressure sores, a precursor to debilitating deep tissue ulcerations. Ulcerations are well documented and current socket fitting techniques, as performed by a “prosthetist,” are largely subjective, relying on the prosthetist's experience and feedback from the patient. With the …

Ultra-High Resolution Simulations Of The Atmospheric Boundary Layer Across The Shores Of Lake Erie, Stephen Kennedy
Undergraduate Research Posters 2015
An accurate assessment of wind speeds at various heights and locations is important in the deployment of wind turbines. This study focuses on assessing wind speeds and their trends across the shores of the Lake Erie by unsteady, three dimensional, Large Eddy Simulations (LES) with a horizontal resolution of 50m. In a previous study the Weather Research and Forecasting (WRF) was used for the same region with a coarser resolution of 3km. It did not consistently predict the wind speeds, especially for a well- known nocturnal phenomenon—the Low Level Jet. Our LES code, DALES (Dutch Atmospheric Large Eddy Simulation), seems …

Undergraduate Research Posters 2015
Wind energy has become a major contributor to energy production from renewable sources and is expected to increase its portion to the overall energy supply. Wind-tunnel testing of miniature wind turbine models plays an important role in understanding the turbine wake effects and interactions of wind farms with the incoming flow. However, previous research has often not carefully quantified the rotor aerodynamic characteristics of the mini wind turbines, i.e., how the power and thrust coefficients vary with respect to the tip speed ratio, and to what extent they represent the field-scale wind turbines. This work focuses on developing a robust …

Privacy-Aware Computer-Vision Based Human Motion Tracking, Connor Gordon, Abou-Bakar Fofana
Undergraduate Research Posters 2015
Computer-vision based human motion tracking has undergone intensive research for the past several decades. As exemplified by Microsoft Kinect, inexpensive portable computer-vision based motion sensors can now be used to accurately track human motions in many application domains, particularly in the healthcare area, such as rehabilitation exercises, fall detection, and safe patient handling. However, such computer-vision based technology is rarely used in venues such as hospitals and nursing homes, primarily due to privacy concerns. Even if a patient or a health caregiver has consented to being monitored, the vision-based motion sensor cannot guarantee that only the consented person is tracked …
