Integration And Characterization Of An Electrical Storage System For A Hydrogen Fuel Cell Plug-In Hybrid Electric Vehicle, Edward Alexei Anculle Arauco

Masters Theses

"Hydrogen fuel cell hybrid vehicles are an advance technology that promises to solve the energy crisis in transportation and green houses emissions. Even more, Plug-in or extended range vehicles can add diversity in energy sources. Extended range vehicles have the capability to extract energy from the grid and hence reduce the cost of operation of the vehicle. EcoCAR: the NeXt Challenge is a Noth [sic] American competition with seventeen schools participating across North America. Missouri S&T is developing a Fuel Cell Plug-in Hybrid electric vehicle which has a large lithium-ion battery able to store 16 kWh. The fuel cell powertrain …

A Real-Time Visualization Of An/Pss-14 Audio Alert Signals For Land Mine Detection Validation, Nitin Kolekar

Masters Theses

"The central idea of the current research is visualization of audio alerts from AN/PSS-14. A visualization device connected to the arm of PSS-14 will show real-time display of MD and GPR Audio Alert signals from PSS-14. This visualization device displays both amplitude-time and spectral frequency-time formats of the signals. The latter format achieves visual separation of combined, simultaneous, MD and GPR alerts. The joint occurrence of MD and GPR signals in a specific time window confirms the presence of landmine. This window is defined by the time of occurrence of MD peak and time of occurrence GPR diffraction from onset …

In Search Of Something More: My Path Towards International Service-Learning In Engineering Education, Margaret Pinnell

Mechanical and Aerospace Engineering Faculty Publications

My personal and professional travels led me toward global education, in particular the University of Dayton (UD) program Engineers in Technical Humanitarian Opportunities for Service-Learning (ETHOS). I do not believe I ever intended to become part of an international engineering education program. In fact, I think the international piece was just a bonus. What really drew me to the ETHOS program was what initially draws our students to the program - a desire to "help" people. In order for the reader to understand how I ended up being involved in global education through the ETHOS program, I must first explain …

Gains In Knowledge And Perception Of Engineering After Participation In An Engineering Design Web-Experience Are Gender-Dependent, Kimberly Edginton Bigelow, Gail Wheatley, David Tomasko

Mechanical and Aerospace Engineering Faculty Publications

Web-based activities have the potential to teach engineering in both formal and informal science education settings, maximizing outreach efforts. To date, many activities available on the internet teach about engineering, but few allow students to truly “do” engineering.

This project utilized web animation and interaction in the design of a web-based experience focused on engineering design. In this activity, targeted toward middle school students, users played the role of engineer and engaged in the process of designing a cell phone for the older adult market. It was hoped that this web-based activity would increase participant understanding of what engineering is …

A Novel Far-Field Nanoscopic Velocimetry For Nanofluidics, C. Kuang, Guiren Wang

Faculty Publications

For the first time we have been able to measure the flow velocity profile for nanofluidics with a spatial resolution better than 70 nm. Due to the diffraction resolution barrier, traditional optical methods have so far failed in measuring the velocity profile in a nanocapillary or a closed nanochannel without an opened sidewall. A novel optical point measurement method is presented which applies stimulated emission depletion (STED) microscopy to laser induced fluorescence photobleaching anemometer (LIFPA) techniques to measure flow velocity. Herein we demonstrate this far-field nanoscopic velocimetry method by measuring the velocity profile in a nanocapillary with an inner diameter …

Structural Health Monitoring With Piezoelectric Wafer Active Sensors--Predictive Modeling And Simulation, Victor Giurgiutiu

Faculty Publications

This paper starts a review of the state of the art in structural health monitoring with piezoelectric wafer active sensors and follows with highlighting the limitations of the current approaches which are predominantly experimental. Subsequently, the paper examines the needs for developing a predictive modeling methodology that would allow to perform extensive parameter studies to determine the sensing method’s sensitivity to damage and insensitivity to confounding factors such as environmental changes, vibrations, and structural manufacturing variability. The thesis is made that such a predictive methodology should be multi-scale and multi-domain, thus encompassing the modeling of structure, sensors, electronics, and power …
