It Takes A Village: The Role Of Emic And Etic Adaptive Strengths In The Persistence Of Black Men In Engineering Graduate Programs, Brian A. Burt, Krystal L. Williams, Gordon J. M. Palmer
Black men, underrepresented in engineering, constitute a missing segment of the population who could contribute to the global knowledge economy. To address this national concern, stakeholders need additional research on strategies that aid in Black men’s persistence. This study explores the experiences of 30 Black men in engineering graduate programs. Three factors are identified as helping them persist from year to year, and in many cases through completion of the doctorate: the role of family, spirituality and faith-based community, and undergraduate mentors. The article concludes with implications for future research and professional practice that may improve the experiences of ...

As technology continues to develop, external beam radiation therapy is being employed, with increased conformity, to treat smaller targets. As this occurs, the dosimetry methods and tools employed to quantify these fields for treatment also have to evolve to provide increased spatial resolution. The team at the University of Wollongong has developed a pixelated silicon detector prototype known as the dose magnifying glass (DMG) for real-time small-field metrology. This device has been tested in photon fields and IMRT. The purpose of this work was to conduct the initial performance tests with proton radiation, using beam energies and modulations typically associated ...
Adsorption Kinetics Of Pb(Ii) And Zn(Ii) Ions Unto Carbonized Groundnut Shells And Maize Cobs, 2018 Missouri University of Science and Technology
Adsorption Kinetics Of Pb(Ii) And Zn(Ii) Ions Unto Carbonized Groundnut Shells And Maize Cobs, Leke Luter, Aboi Julius, Henry T. Dekaa, B. A. Ikyenge, Ande Sesugh, Monday Uchenna Okoronkwo
Monday Uchenna Okoronkwo
Maize cobs and groundnut shell adsorbents from agricultural by-products were carbonized and investigated for adsorption of two selected metals, Lead (Pb II) and Zinc (Zn II) from aqueous solutions of these metals. Kinetic studies of the adsorption processes were investigated employing Elovich and the intraparticle diffussion models. The results showed that, the adsorption capacities of these comparatively cheaper adsorbents and their efficiency for the removal of Pb(II) and Zn(II) ions from aqueous solution present them suitable for use in place of the costly commercial activated carbons.

Hydrodynamics Of An Anguilliform Swimming Motion Using Morison’S Equation, 2018 University of New Orleans
Hydrodynamics Of An Anguilliform Swimming Motion Using Morison’S Equation, Naga Sasi Devarakonda
University of New Orleans Theses and Dissertations
In this study, the hydrodynamic performance of anguilliform swimming motion is computed using Morison’s equation. This method was shown to predict the servo motor torques well. The anguilliform swimming motion is sinusoidal with increasing amplitude from head to tail. A “wakeless” swimming motion proposed by Vorus and Taravella (2011) with zero net circulation is considered.
This method is compared to the existing slender body theory and is validated with reference to the experimental results of NEELBOT-1.1 (Potts, 2015). The results for the study indicates that self-propulsion speed of the motion is independent of the oscillating tail amplitude at ...

Thermal Properties Of Spinel Based Solid Solutions, 2018 Missouri University of Science and Technology
Thermal Properties Of Spinel Based Solid Solutions, Kelley R. Wilkerson
Kelley R. Wilkerson
"Solid solution formation in spinel based systems proved to be a viable approach to decreasing thermal conductivity. Samples with systematically varied additions of MgGa₂O₄ to MgAl₂O₄ were prepared and thermal diffusivity was measured using the laser ash technique. Additionally, heat capacity was measured using differential scanning calorimetry and modeled for the MgAl₂O₄-MgGa₂O₄ system. At 200⁰C thermal conductivity decreased 24% with a 5 mol% addition of MgGa₂O₄ to the system. The solid solution continued to decrease the thermal conductivity by 13% up to 1000⁰C with 5 mol% addition. The decrease in thermal conductivity ultimately resulted in a decrease in heat flux ...

Self-Healing Control With Multifunctional Gate Drive Circuits For Power Converters, 2018 Missouri University of Science and Technology
Self-Healing Control With Multifunctional Gate Drive Circuits For Power Converters, Peng Xiao, Ganesh K. Venayagamoorthy, Keith Corzine, Robert S. Woodley
Robert S. Woodley
Many commercial and military transport systems have fault diagnostic functions implemented to help protect the device when a severe fault occurs. However, most present systems do not contain prognostics capability which would allow operators to observe an unhealthy system component in its pre- fault condition. In industry applications, scheduled downtime can result in considerable cost avoidance. The next technology step is self-healing system components which observe not only potential problems, but can also take steps to continue operation under abnormal conditions - whether due to long-term normal wear-and-tear or sudden combat damage. In this paper, current and voltage information using the ...
An Approach To Active Sensor Imaging, 2018 Missouri University of Science and Technology
An Approach To Active Sensor Imaging, Askin Demirkol, Levent Acar, Robert S. Woodley
Robert S. Woodley
In this paper, an alternative Target Density Function (TDF) is proposed to image the radar targets in a dense target environment. It is obtained by considering a novel range and scanning angle plane different from the conventional methods. An alternative method is briefly proposed for smoothing the target density function by taking advantage of Walsh functions. Although the imaging is obtained via the phased array radars, the problem associated with beamforming in linear phased array radar system is bypassed in this new algorithm.

In this paper, an alternative Target Density Function( TDF) is proposed for narrowband radar model. This is achieved by estimating a new target density function by Gabor theory. It is shown how Gabor transform can be used to obtaining wideband target density function by transmitting a waveform which is a kernel for this transform. The windowing characteristics of this theory is plausible to reaching an accurate result. The presented wideband target density function is developed in a various manner different from the conventional methods.

Development Of A Subsurface Landfill Fire Risk-Index, Samain Sabrin
Theses and Dissertations
Landfill subsurface fires create environmental hazards by emitting potentially dangerous particulates into the atmosphere and damaging liners, potentially contaminating surrounding soil and groundwater aquifers with leachate. Currently, the only means of detecting underground fires are physical tests. This paper is used to describe an index that can be employed to track fire risk across a landfill. The landfill parameters analyzed for fire risk susceptibility in Chapter 1 include residual nitrogen concentration, oxygen exceedance, methane concentration, carbon monoxide level, methane and carbon dioxide ratio and monitoring well temperature. Incorporating these factors, a landfill fire index ranging from 1 to 10 was ...

Impact Of Trace Element Ions And Fe2+ On Anaerobic Food Waste Digestion, Andisheh Yazdanpanah
Electronic Thesis and Dissertation Repository
In Canada, about $31 billion worth of food is wasted annually. This amount of food waste (FW) ends up in landfills where it is naturally broken down by bacteria and releases methane to the atmosphere, a powerful greenhouse gas (GHG) which is 21 times more harmful to the environment than carbon dioxide (CO2). This process can also be done in a controlled environment at wastewater treatment plants, in a process known as anaerobic digestion (AD). Diverting food waste from landfills to wastewater treatment facilities allows for the capture of the methane, which can be used as an energy source ...
