Kitchen Table Meetings: Applying The Golden Rule To Property Owner Outreach, David N. Goffinet, David Pluckebaum

Purdue Road School

Property impacts are unavoidable with most road construction. Rather than the owner’s first experience being a drilling rig pull up in their drive-way, the kitchen table meeting process takes a proactive approach to sitting down in the “safety and comfort” of their home, upfront to discuss the type and timing of activities that will occur during design, property acquisition and construction— reducing the “unknown” in this multi-year process that happens too fast for some and too slowly for others. Learn how this approach has not only resulted in increased project acceptance and perception, but also in valuable knowledge that can …

Application Of Sub-Micrometer Vibrations To Mitigate Bacterial Adhesion, Will R. Paces, Hal Holmes, Eli Vlaisavljevich, Katherine L. Snyder, Ee Lim Tan, Rupak Rajachar, Keat Ghee Ong

Michigan Tech Publications, Part 1

As a prominent concern regarding implantable devices, eliminating the threat of opportunistic bacterial infection represents a significant benefit to both patient health and device function. Current treatment options focus on chemical approaches to negate bacterial adhesion, however, these methods are in some ways limited. The scope of this study was to assess the efficacy of a novel means of modulating bacterial adhesion through the application of vibrations using magnetoelastic materials. Magnetoelastic materials possess unique magnetostrictive property that can convert a magnetic field stimulus into a mechanical deformation. In vitro experiments demonstrated that vibrational loads generated by the magnetoelastic materials significantly …

Zno Nanosheet Arrays Constructed On Weaved Titanium Wire For Cds-Sensitized Solar Cells, Cuncun Wu, Lin Wei, Yitan Li, Chang Liu, Jun Jiao, Yanxue Chen, Liangmo Mei

Mechanical and Materials Engineering Faculty Publications and Presentations

Ordered ZnO nanosheet arrays were grown on weaved titanium wires by a low-temperature hydrothermal method. CdS nanoparticles were deposited onto the ZnO nanosheet arrays using the successive ionic layer adsorption and reaction method to make a photoanode. Nanoparticle-sensitized solar cells were assembled using these CdS/ZnO nanostructured photoanodes, and their photovoltaic performance was studied systematically. The best light-to-electricity conversion efficiency was obtained to be 2.17% under 100 mW/cm/cm² illumination, and a remarkable shortcircuit photocurrent density of approximately 20.1 mA/cm² was recorded, which could attribute to the relatively direct pathways for transportation of electrons provided by ZnO nanosheet arrays as …

Determination Of Specific Gravity Of Municipal Solid Waste, Nazli Yesiller, James Hanson, Jason Taylor Cox, Danielle E. Noce

Civil and Environmental Engineering

This investigation was conducted to evaluate experimental determination of specific gravity (G_s) of municipal solid waste (MSW). Water pycnometry, typically used for testing soils was adapted for testing MSW using a large flask with 2000 mL capacity and specimens with 100–350 g masses. Tests were conducted on manufactured waste samples prepared using US waste constituent components; fresh wastes obtained prior and subsequent to compaction at an MSW landfill; and wastes obtained from various depths at the same landfill. Factors that influence specific gravity were investigated including waste particle size, compaction, and combined decomposition and stress history. The …

[M3(Μ3-O)(O2cr)6] And Related Trigonal Prisms: Versatile Molecular Building Blocks For 2-Step Crystal Engineering Of Functional Metal-Organic Materials, Alexander Schoedel

USF Tampa Graduate Theses and Dissertations

Metal-organic materials (MOMs) assembled from metal-based building blocks and organic linkers have attracted much interest due to their large pore dimensions and their enormous structural diversity. In comparison to their inorganic counterparts (zeolites), these crystalline materials can be easily modified to tailor pore dimensions and functionality for specifically targeted properties.

The work presented herein encompasses the development of a synthetic 2-step process for the construction of novel families of MOMs or 'platforms' and allow us exquisite design and control over the resulting network topologies. Examples of cationic mesoporous structures were initially exploited, containing carboxylate based centers connected by metal-pyridine bonds. …

Automated Tracking And Estimation For Control Of Non-Rigid Cloth, Marc D. Killpack

Faculty Publications

This report is a summary of research conducted on cloth tracking for automated textile manufacturing during a two semester long research course at Georgia Tech. This work was completed in 2009. Advances in current sensing technology such as the Microsoft Kinect would now allow me to relax certain assumptions and generally improve the tracking performance. This is because a major part of my approach described in this paper was to track features in a 2D image and use these to estimate the cloth deformation. Innovations such as the Kinect would improve estimation due to the automatic depth information obtained when …

A Reactor Model For Hydrogen Generation From Sodium Borohydride And Water Vapor, Lin Yu, Michael A. Matthews

Faculty Publications

This paper reports new data on the production of hydrogen from water vapor plus NaBH4, or NaBH4 þ 10% CoCl2. Data were collected with the aid of an isothermal semi-batch reactor with in-situ H2 rate measurement. The reaction of NaBH4 to generate H2 proceeds via three steps: deliquescence, dissolution and reaction. The deliquescence regime of NaBH4 in the presence of 10 weight percent CoCl2 is defined. The H2 yield is quantified at various reaction conditions (reaction temperature 70-120 C, relative humidity 31-69%). CoCl2 significantly accelerates the rate of H2 production compared to deliquescence + reaction of pure NaBH4. It is …

A High-Quality Professional Development For Teachers Of Grades 3–6 For Implementing Engineering Into Classrooms, S. Selcen Guzey, Kristina Tank, Hui-Hui Wang, Gillian Roehrig, Tamara J. Moore

School of Engineering Education Faculty Publications

With the increasing emphasis on integrating engineering into K-12 classrooms to help meet the needs of our complex and multidisciplinary society, there is an urgent need to investigate teachers' engineering-focused professional development experiences as they relate to teacher learning, implementation, and student achievement. This study addresses this need by examining the effects of a professional development program focused on engineering integration, and how teachers chose to implement engineering in their classrooms as a result of the professional development. 198 teachers in grades 3–6 from 43 schools in 17 districts participated in a yearlong professional development program designed to help integrate …

A Recreation And Ballistic Evaluation Of Otto Schneeloch's Firearm Curiosity - The .307 Triangular, Amber Nicole Shukitis

USF Tampa Graduate Theses and Dissertations

Otto Scheeloch's U.S. Patent No. 134,442 of 1872 describes a unique firearm that uses triangular bullets. The current research effort evaluates the ballistic performance of Otto's disclosure for the very first time. To achieve this goal it was necessary to seek out surviving artifacts and scour the historical record in search of all the parameters needed to meticulously recreate the curious triangular cartridges and the corresponding gun barrel, with its matching twisted triangular bore. Every aspect of the resulting reproduction ammunition was made to be as authentic as possible, including the use of vintage civil war era bullet lead, bullet …

Theoretical Framework For Multiple-Polymorph Particle Precipitation In Highly Supersaturated Systems, B. B. Schroeder, D. D. Harris, S. T. Smith, D. O. Lignell

Faculty Publications

An overarching mathematical framework is proposed to describe entire mineral particle precipitation processes, including multiple polymorphic forms and ranges of temperatures. While existing models portray individual physical phenomena, the presented approach incorporates a diverse set of the physical phenomena simultaneously within a single mathematical description. The liquid and solid phase dynamics interact through coupling an aqueous ionic equilibrium-chemistry model with a set of population balance equations and a mixing model. Including the particle physical phenomena, nucleation, growth, dissolution, and aggregation together within a single framework allows for the exploration of nonintuitive and nontrivial coupling effects. To validate the proposed framework, …
