Propeller And Propeller-In-Wing Thrust Vectoring, Grace G. Culpepper

Honors Theses

This research investigates the efficiency of a vane-based thrust vectoring system set in the wake of a propeller, supporting forward force at a minimum loss in net thrust. The vectoring system itself is placed in both a standalone propeller configuration and a propeller-in-wing configuration. Both static and wind-on force-based experiments are conducted at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) with off-the-shelf R/C propellers. Sensitivity analysis determines both the effect of vane deflection angle on thrust vectoring and the effect of propeller placement with respect to the upper surface of the integrated wing on system performance. Static test …

Development Of A Computational Framework For Estimating Knee Joint Contact Forces In Running, Sean W. Kapp

Honors Theses

The prevalence of running as a form of exercise and the necessity of walking for simple locomotion obscure massive forces and moments within the body. An especial area of concern is the knee, as common among these injuries is knee pain as a result from high impact on the ground or ground reaction forces. These forces are altered by the foot strike pattern of the individual; in this study, either rearfoot strike (RFS) or forefoot strike (FFS). This alteration will impact internal forces conducted upward through the body. Given the complexity of the motion of running and the forces involved, …

Comparison Of Tensile Properties Of Triaxial Braided Carbon Fiber Composites Made From Vacuum Assisted Resin Transfer Molding (Vartm) And Autoclave Molding, Donald A. Klosterman, Charles Browning

Chemical and Materials Engineering Faculty Publications

Triaxially braided fiber composites are increasingly being used in aerospace, ballistic, and sporting good applications due to their inherent damage tolerance, torsional stability, and cost compared to woven fabrics and unidirectional preforms. There have been numerous publications over the past 15-20 years on the mechanical properties and failure mechanisms of triaxial braided composites. However, most of these have involved panels made with autoclave curing. In the present study, braided carbon fiber composites were made using autoclave curing and vacuum assisted resin transfer molding (VARTM). The goal of the study was to compare the physical and tensile properties of quasi-isotropic panels …

Detection And Aggregation Of Listeria Monocytogenes Using Polyclonal Antibody Gold-Coated Magnetic Nanoshells Surface-Enhanced Raman Spectroscopy Substrates, Robert T. Busch, Farzia Karim, Yvonne Sun, H. Christopher Fry, Yuzi Liu, Chenglong Zhao, Erick S. Vasquez

Chemical and Materials Engineering Faculty Publications

Magnetic nanoshells with tailored surface chemistry can enhance bacterial detection and separation technologies. This work demonstrated a simple technique to detect, capture, and aggregate bacteria with the aid of end-functionalized polyclonal antibody gold-coated magnetic nanoshells (pAb-Lis-AuMNs) as surface-enhanced Raman spectroscopy (SERS) probes. Listeria monocytogenes were used as the pathogenic bacteria and the pAb-Lis-AuMNs, 300 nm diameter, were used as probes allowing facile magnetic separation and aggregation. An optimized covalent bioconjugation procedure between the magnetic nanoshells and the polyclonal antibody was performed at pH six via a carbodiimide crosslinking reaction. Spectroscopic and morphological characterization techniques confirmed the fabrication of stable pAb-Lis-AuMNs. …

Tep1 Regulates Yki Activity In Neural Stem Cells In Drosophila Glioma Model, Karishma Gangwani

Graduate Student Showcase

Glioblastoma is the most common form of malignant brain tumor with a poor prognosis. Using a Drosophila glioma model, we showed that the Drosophila Tep1 gene (human CD109) regulates Yki (human YAP/TAZ) via an evolutionarily conserved mechanism. Oncogenic signaling by the YAP/TAZ pathway occurs in cells that acquire CD109 expression. Loss of Tep1 caused a reduction in glioma growth. Further, Tep1 affects Yki mediated stem cell renewal in glioma, as reduction of Tep significantly decreases the number of neuroblasts in glioma. Thus, we identify Tep1-Yki interaction in the larval CNS that plays a key role in glioma growth and progression.

Optical Dilatometry Measurements For The Quantification Of Sustainable Aviation Fuel Materials Compatibility, Shane Kosir

Graduate Student Showcase

Sustainable aviation fuel (SAF) offers a near-term opportunity to reduce aviation’s greenhouse gas emissions. Currently-approved SAFs are limited to a maximum blend ratio with conventional jet fuel due to materials compatibility issues (i.e., O-ring volume swell). Specifically, aircraft have been found to leak significant quantities of fuel when volume swell is insufficient. Here, optical dilatometer measurements of volume swell for SAFs are reported. These measurements will serve to screen candidate SAFs at an early stage of the approval process. Optical dilatometry measurements were also coupled with two-dimensional gas chromatography data to predict volume swell withfuel.

Chronic Administration Of The Novel Serca2 Activator Cdn1163 Induces Behavioral Andneurochemical Effects In Mice, Aikaterini Britzolaki

Graduate Student Showcase

The sarco/endoplasmic reticulum (SR/ER) calcium (Ca2+)-ATPase (SERCA) pump is a key regulator of intracellular Ca2+ homeostasis and subsequently essential for cell survival and function [1,2]. Neurons are no exception to this; intricate pathways involving SERCA-mediated Ca2+ signaling are implicated in brain pathophysiology. Several studies have indicated that dysregulation of SERCA pumps may be involved in the molecular mechanisms underlying debilitating brain diseases including Alzheimer’s and Parkinson’s diseases, schizophrenia, bipolar disorder, ischemia and alcoholism [1-3]. Thus, this family of P-type ATPases comprises an emerging molecular target for developing efficient pharmacotherapies. Interestingly, preclinical studies in rodents suggest that chronic pharmacological activation of …

Binder Free, Thin-Film Ceramic Coated Separators For Improved Safety Of Lithium-Ion Batteries, Ashish Gogia, Yuxing Wang, Amarendra K. Rai, Rabi Bhattacharya, Guru Subramanyam, Jitendra Kumar

Graduate Student Showcase

With the rapid development of lithium-ion batteries (LIBs), safety issues are the greatest obstacles that restrict their large scale-applications, especially for the high-energy-density electric vehicle and aviation industry. Separators play a crucial role in ensuring the safety of LIBs. However, due to their poor thermal stability, commercial polyolefin-based separators such as polyethylene (PE) still possess serious safety risks under abuse conditions. To address these challenges, a novel type of binder-free, thin ceramic-coated separator with superior safety characteristics is demonstrated in this research.

Smart WiFi thermostats, when they first reached the market, were touted as a means for achieving substantial heating and cooling energy cost savings. These savings did not materialize until additional features, such as geofencing, were added. Today, average savings from these thermostats of 10–12% in heating and 15% in cooling for a single-family residence have been reported. This research aims to demonstrate additional potential benefit of these thermostats, namely as a potential instrument for conducting virtual energy audits on residences. In this study, archived smart WiFi thermostat measured temperature data in the form of a power spectrum, corresponding historical weather …
