Integrating An Android Device Into Embedded Computer Systems, Eric Payne Jan 2015

Integrating An Android Device Into Embedded Computer Systems, Eric Payne

Undergraduate Research Posters 2015

An embedded system is a computer system designed to perform a specific set of tasks such as a GPS device or a digital camera. An embedded system is composed of three major parts: a processor (CPU), input devices, and output devices. The input devices are peripherals to take user command (switches and keypad) and sensors to measure environmental conditions (barometer and accelerometer). The output devices are actuators that generate light and sound (LED display and amplified speaker) and moving parts (servo motor). An important step in prototyping an embedded system is to design the input subsystem. It is traditionally done …

Characterization Of Rotor Aerodynamics Of The Laboratory-Scale Miniature Wind Turbines, Jason Wolf, Jordan Thomas Jan 2015

Characterization Of Rotor Aerodynamics Of The Laboratory-Scale Miniature Wind Turbines, Jason Wolf, Jordan Thomas

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 …

Ultra-High Resolution Simulations Of The Atmospheric Boundary Layer Across The Shores Of Lake Erie, Stephen Kennedy Jan 2015

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 …

Privacy-Aware Computer-Vision Based Human Motion Tracking, Connor Gordon, Abou-Bakar Fofana Jan 2015

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 …

Selective Plane Illumination Microscopy, David Ian Pendleton Jan 2015

Selective Plane Illumination Microscopy, David Ian Pendleton

Undergraduate Research Posters 2015

Selective plane illumination microscopy (SPIM), or light sheet microscopy, is a microscopy technique that allows you to acquire high resolution fluorescence images of biological samples by illuminating the sample with a thin plane from the side, instead of along the imaging axis as in traditional transillumination or epi-illumination. The purpose of this SPIM research assignment was to combine two previously built systems, an inverted SPIM and a tunable lens system. This report includes use of optics, coupling lasers and proper technique to building optical systems. Programming in Matlab, LabVIEW, and other programming languages was used to synchronize the shutter and …

Tuning The Size Of Elastin-Like Polypeptide Nanoparticles, Adam Maraschky Jan 2015

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 Jan 2015

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 …

Prosthetic Socket Surface Initialization – For Future Use In Subject-Specific Socket Optimization, Brahm Powell Jan 2015

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 …

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

Terahertz radiation is invaluable in spectroscopy and imaging due to its nondestructive nature. It has become a key focus for those wishing to develop sensors capable of detecting weapons and narcotics unobtrusively and at a distance. An ultrafast pulsed (femtoseconds) laser incident on a superconducting ring causes the emission of terahertz (THz) radiation. It is theorized that the radiation is a result of the supercurrent being modulated by the breaking and recombining of Cooper pairs on the order of picoseconds, where the time scale determines the frequency of the emitted radiation. We propose to investigate the terahertz emission from Yttrium …

Strain Controlled Ultra-Low-Energy Magnetic Tunneling Junction, Hasnain Ahmad, Supriyo Bandyopadhyay, Jayasimha Atulasimha Jan 2015

Strain Controlled Ultra-Low-Energy Magnetic Tunneling Junction, Hasnain Ahmad, Supriyo Bandyopadhyay, Jayasimha Atulasimha

Graduate Research Posters

We are experimenting on designing a voltage-controlled ultra-low-energy Magnetic Tunneling Junction (MTJ) device using a soft single domain magnetostrictive layer (i.e. Galfenol: Fe1-xGax , x = 20 At%) coupled to a piezoelectric layer (i.e. PMN-PT). Special metal pads have been designed using photolithography to generate stress in the PMN-PT layer by applying electric field. The patterns of different shape anisotropic nano-magnets are designed using e-beam lithography and we have successfully fabricate FeGa nanomagnets with only 12 to 13 nanometer thickness by sputter deposition. These nanomagnets have been characterized by magnetic force microscopy for observing their switching capabilities. …

Coherent Spin Transport In Nanowire Spin Valves And Novel Spintronic Device Possibilities, Md Iftekhar I. Hossain, Supriyo Bandyopadhyay, Jayasimha Atulasimha, Saumil Bandyopadhyay

Graduate Research Posters

We have proposed a spintronic infrared photodetector backed by experimental evidence and matched with theoretical prediction obtained in our labs. Unlike conventional photodetectors, it can work at room temperature with ideally infinite light-to-dark contrast ratio, infinite detectivity and zero dark current. The proposed idea is based on smart implementation of spin polarized transport. Electrons while travelling through one-dimensional channel show long spin relaxation length if they can be confined to a single conduction subband because of the elimination of major spin relaxation mechanism, namely the D’yakonov-Perel’ mechanism. With infrared light, electrons can be excited to higher subbands, resulting in the …

Fluorescent Biosensors To Measure Endothelial Cell Responses To Fluid Shear Stress, Natalie Noll Jan 2015

Fluorescent Biosensors To Measure Endothelial Cell Responses To Fluid Shear Stress, Natalie Noll

Undergraduate Research Posters

The response of endothelial cells, innermost layer of blood vessels, to blood flow is thought to be critical in the initiation and progression of atherosclerosis. Atherosclerosis in the human body is non-random and is highly correlated to vessel sites which experience oscillatory and reversing blood flow. Endothelial cells (ECs), the inner most cell layer of blood vessels are highly responsive to the drag force from blood flow, known as shear stress. To study endothelial cell responses to shear stress we used a parallel plate flow chamber in which we exposed endothelial cells to defined fluid shear stress. Using fluorescence resonance …

Design And Creation Of A Device To Induce Vergence Eye Movements, Jacob B. Jaminet, Paul A. Wetzel

Undergraduate Research Posters

Automated eye-tracking systems can detect and analyze eye movements as a means to accurately diagnose more than 20 neurological diseases including mild traumatic brain injury. Mild traumatic brain injury is an occurrence of injury to the head resulting from blunt trauma or from acceleration or deceleration forces. Eye movement refers to the voluntary or involuntary movement of the eyes, helping in acquiring, fixating and tracking visual stimuli. There are three types of voluntary eye movement to track objects: smooth pursuit, vergence shifts and saccades. Vergence shifts are eye movements where the eyes move in opposite directions: moving to the midline …
