A Study On The Comparison Of Sample Location Of Pultruded Composites Exposed To Corrosive Environment, Md Mahmudul Hasan
A Study On The Comparison Of Sample Location Of Pultruded Composites Exposed To Corrosive Environment, Md Mahmudul Hasan
Electronic Theses and Dissertations
Composite structures may experience different environments during their prolonged service life. These environments may include corrosive, acidic or both or many others that can adversely affect the mechanical properties of the structural composites. Various studies have been done on the environmental effects on the composites but only a few are on structural shaped pultruded composites. More specifically, none of the studies tell anything about the effects of corrosive media on the locations of the structural shaped pultruded composites coupon samples. Hence, this current study focused on two primary objectives, 1) the durability characterization of structural shaped pultruded composites after an …
Design And Implementation Of Periodic Unsteadiness Generator For Turbine Secondary Flow Studies, Nathan James Fletcher
Design And Implementation Of Periodic Unsteadiness Generator For Turbine Secondary Flow Studies, Nathan James Fletcher
Browse all Theses and Dissertations
A primary source of periodic unsteadiness in low-pressure turbines is the wakes shed from upstream blade rows due to the relative motion between adjacent stators and rotors. These periodic perturbations can affect boundary layer transition, secondary flow, and loss generation. In particular, for high-lift front-loaded blades, the secondary flowfield is characterized by strong three-dimensional vortical structures. It is important to understand how these flow features respond to periodic disturbances. A novel approach was taken to generate periodic unsteadiness which captures some of the physics of turbomachinery wakes. Using stationary pneumatic devices, pulsed jets were used to generate disturbances characterized by …

Mechanical Stresses On Nasal Mucosa Using Nose-On-Chip Model, Zachary Edward Brooks
Browse all Theses and Dissertations
The objective of this research was to design and fabricate a nose-on-chip device and bi-directional airflow system that models flow within the nasal cavity to investigate how airflow induced mechanical stresses impact nasal secretion rates and cytoskeletal remodeling. This research hypothesizes that the airflow induced shear stresses on the nasal mucosa will influence mucus production and the cytoskeleton of the cells. The RPMI 2650 cell line was used to model the nasal mucosa. The system was used to replicate the wall shear stresses (WSS) and wall shear forces (WSF) present in the anterior region of the nose. The WSS and …

Towards Analytical Techniques For Systems Engineering Applications, Griselda Valdepeñas Acosta
Open Access Theses & Dissertations
One of the main objectives of systems engineering is to design, maintain, and analyze systems that help the users. To design an appropriate system for an application domain, we need to know: what are the users' desires and preferences (so that we know in what direction we should aim to change this domain), what is the current state and what is the dynamics of this application domain, and how to use all this information to select the best alternatives for the system design and maintenance. Designing a system includes selecting numerical values for many of the parameters describing the corresponding …
Monitoring Cerebral Functional Response Using Scmos-Based High Density Near Infrared Spectroscopic Imaging, Dharminder Singh Langri
Monitoring Cerebral Functional Response Using Scmos-Based High Density Near Infrared Spectroscopic Imaging, Dharminder Singh Langri
Browse all Theses and Dissertations
Neurovascular coupling is an important concept that indicates the direct link between neuronal electrical firing with the vascular hemodynamic changes. Functional Near Infrared Spectroscopy (fNIRS) can measure changes in cerebral vascular parameters of oxy-hemoglobin and deoxyhemoglobin concentrations and thus can provide neuronal activity through neurovascular coupling. Currently many commercial fNIRS devices are available, but they are limited by the number of channels (usually having only 8 detectors), which can limit the sensitivity, contrast, and resolution of imaging. High-density imaging can improve sensitivity, contrast, and resolution by providing many measurements and averaging the signals originating from the target cerebral focus area …

Natural resources are essential structures of socio-economic systems which shape the well-being of humanity, environment, and the economy. Human actions have become the critical responsibility for environmental changes and pressuring many planetary boundaries. Having a systematic approach can provide a governance platform including the inherent characteristics of the resource, the historically established form of use, and transaction costs. A natural resource governance framework is developed by applying Blockchain technology as the primary goal of this study to regulate and manage the extraction and trades. Blockchain technology provides a distributed concurrency monitoring system for sustainable resource management. Persistent and pervasive cooperation …
On Hybrid Temporal Basis Functions For Stable Numerical Solution Of Time Domain Boundary Integral Equations, Fang Q. Hu
On Hybrid Temporal Basis Functions For Stable Numerical Solution Of Time Domain Boundary Integral Equations, Fang Q. Hu
Mathematics & Statistics Faculty Publications
Problems in unsteady aerodynamics and aeroacoustics can sometimes be formulated as integral equations, such as the boundary integral equations. Numerical discretization of integral equations in the time domain often leads to so-called March-On-in-Time (MOT) schemes. In the literature, the temporal basis functions used in MOT schemes have been largely limited to low-order shifted Lagrange basis functions. In order to evaluate the accuracy and effectiveness of the temporal basis functions, a Fourier analysis of the temporal interpolation schemes is carried out. Based on the Fourier analysis, the spectral resolutions of various temporal basis functions are quantified. It is argued that hybrid …

Development Of Physics Based Machine Learning Algorithms, Rob Jennings
Master’s Theses
In this study, a baseball pitch was examined to try to understand its behavior, and make a predictive model of it. A baseball pitch was tested experimentally with a wind tunnel and modeled computationally with COMSOL CFD software. Five input variables (spin rate, sting angle, seam orientation: Y axis, seam orientation: Z axis, and air velocity) were controlled, with force in three axes recorded as outputs. The experimental and computational results were examined and seen to be interdependent for all input variables. Experimental and computational data were both insufficient for predicting system behavior. Experimental data collection would have required an …

Project "Auxilia" - Jaiden's Prosthetic Arm, Christopher Halley, Lindsay Jaros, Autumn Young
Williams Honors College, Honors Research Projects
The main objective of this project was to create a prosthetic arm for a 15 year old boy named Jaiden Foden. Jaiden was born with only one fully developed limb as a result of a genetic disorder, Hanhart Syndrome II. His right arm becomes a residual limb below the elbow, but has two fingers which act in a “claw-like” movement. Jaiden’s left arm becomes a residual limb above the elbow, and his left leg becomes a residual limb above the knee. The goal of the arm was to increase Jaiden’s overall independence and to help in completing daily tasks, such …

This design project will aim to provide archery hunters with a platform to simulate shooting at string jumping deer. String jumping refers to a spooked deer hearing the snap of a bow string and instintivly ducking up to ten inches. This often results in wounded or missed deer. We will design and build a control system that uses the sound of a bow string as a trigger to operate a mechanical target system. A sound sensor will mimic a deer’s hearing in close range hunting and then send a signal to the mechanical system to replicate the dropping motion of …

Recent advancements in virtual environment (VE) technology and the growth of VE use in treating and training individuals are opening up new possibilities for rehearsal in safe and rich environments. Research has shown that VEs can be used to treat those with Post Traumatic Stress Disorder (PTSD), but very little research has been done to suggest good guidelines for creating an effective environment. This research was conducted to help inform the design of systems that let veterans rehearse potentially stressful experiences in a safe environment before having to physically step into that environment. We investigated responses to specific design components …

Usually power take off (PTO) with a two-spool turbofan engine has been accomplished via the high pressure (HP) shaft and bleed air from the high-pressure compressor (HPC). The PTO is used to run various aircraft components such as generators and hydraulic pumps, which also produce waste heat. To better understand the coupled transient nature of balancing engine thrust, power take off and thermal management, a transient variable cycle three stream turbofan engine model has been developed to investigate the integrated behavior. The model incorporates many dynamic features including a third-stream heat exchanger as a heat sink for thermal management and …
Investigative Study Of Poly(Ionic) Liquid Incorporation In Resin Wafer Electrodeionization For Improved Specific Energy Consumption, Angela Fasuyi
Investigative Study Of Poly(Ionic) Liquid Incorporation In Resin Wafer Electrodeionization For Improved Specific Energy Consumption, Angela Fasuyi
Electronic Theses and Dissertations
An electrokinetic separation method known as Resin Wafer Electrodeionization (RW-EDI) is recognized as a promising technology for energy efficient desalination of brackish water. However RW-EDI is limited by an inherent drawback of its ion exchange media that prevents the largescale deployment of this technology. This research was undertaken to optimize the conventional resin wafer used in RW-EDI through the incorporation of high conducting polyionic liquids (PILs). It was hypothesized that by the changing non-conducting polyethylene binder with a PIL binder in conventional resin wafer configurations ion conductivity within the resin bed would be enhanced and could lead to an improvement …

Williams Honors College, Honors Research Projects
Akron Children’s Hospital and The University of Akron’s Biomedical Engineering Design Team Engineering Forward have paired together to improve medical adapted helmets for post-operative and disabled patients. An issue is the helmets are only produced in a couple of sizes. Also, it is a tedious process to constantly adjust the pressure on the patient’s cranium within a trial-and-error process. Engineering Forward plans to improve the effectiveness of this helmet by creating an adjustable helmet that can read the pressure on a patient’s head. The caregiver can then make the necessary adjustments to the helmet to accommodate the patient. Documents of …

Wideband technology has been applied to many wide bandwidth applications when there is a need to send much different information in a short time from one point and received from another point in high precision and accuracy. A wideband receiver reports a signal without tuning if the signal is within the input bandwidth. The analog Instantaneous Frequency Measurement (IFM) receiver has been used for decades to cover a very wide input bandwidth and report one accurate frequency on a short pulse at a time. The digital IFM use a high sampling rate ADC to operate in a wide bandwidth, Hilbert …

As-Manufactured Modeling Of A Mistuned Turbine Engine Compressor Evaluated Against Experimental Approaches, Daniel L. Gillaugh
Browse all Theses and Dissertations
As-manufactured rotors behave quite differently than nominal, as-designed rotors due to small geometric and material property deviations in the rotor, referred to as mistuning. Traditional integrally bladed rotor (IBR) modeling approaches assume each blade is identical. State-of-the-art IBR dynamic response predictions can be accomplished using asmanufactured models (AMM) generated via optical topography measurements and mesh morphing. As-manufactured models account for geometric deviations occurring through the machining process, material deviations and field wear, allowing each blade to respond differently. Rotor designs are intended to avoid resonance crossings throughout an engine’s operating range, but total avoidance is challenging. This has led to …
