The Enhancement Of Peroxide-Cured Fluoroelastomer Rubber To Metal Bonding, Richard Hunter Cooke Iii

Browse all Theses and Dissertations

A "combi-cured&" fluoroelastomer (FKM) rubber formulation was designed to yield 100% cohesive rubber failure when cured to cold-rolled steel with derivatives of polymeric silane adhesives. Three different categories of adhesives were tested: Unsaturated Polymeric Silane with Phosphonium Salt (UPSP-D), Unsaturated Polymeric Silane (UPS-L), and Saturated Polymeric Silane (SPS-L). Adhesion Inserts molded using ASTM Method D429 Method C all consistently yielded 100% cohesive rubber failure and showed adhesion strength in the range of 700 to 800 psi after being pulled at 2" per minute until break. After obtaining consistent 100% rubber failure, a design of experiment (DOE) was implemented to determine …

Factors Affecting Uptake Of, And Adherence To, Treatment For Latent Tuberculosis Infection In Ventanilla, Peru, Mariano Matias Iberico Lozada

Master of Public Health Program Student Publications

In Peru, treatment for latent tuberculosis infection (LTBI) with isoniazid is free for all people younger than 20 who have been in close contact with a person with active pulmonary tuberculosis (TB). Despite the availability of this drug therapy within the context of a TB control program that exceeds the international standards for TB care, very few children access, and even fewer complete a full course of treatment. This study was done in order to understand which factors contribute to latent tuberculosis infection treatment uptake and adherence, and whether a socio-economic intervention could improve uptake and adherence of treatment for …

A Hybrid Approach To Finding Relevant Social Media Content For Complex Domain Specific Information Needs, Delroy H. Cameron, Amit P. Sheth, Nishita Jaykumar, Gaurish Anand, Krishnaprasad Thirunarayan, Gary Alan Smith

Kno.e.sis Publications

While contemporary semantic search systems offer to improve classical keyword-based search, they are not always adequate for complex, domain specific information needs. Some complex search situations require knowledge of both ontological concepts as well as 'intelligible constructs' not typically modeled in ontologies. Intelligible constructs convey essential information, which may be important to the holistic information needs of information seekers. Such constructs may include notions of intensity, frequency, interval, dosage, emotion, sentiment, equivalence, synonymy, negation, parts-of-speech, etc. However, few search systems utilize both structured background knowledge (ontologies) and the aforementioned knowledge for query interpretation in domain specific searches. Instead, there is …

Educating Students With Learning Disabilities In Inclusive Classrooms, Jeremy Ford

Electronic Journal for Inclusive Education

There is great debate over including students with disabilities, in particular students with learning disabilities, in inclusive classrooms. Several strategies are available to support educating students with learning disabilities in inclusive classrooms including: co-teaching, differentiated instruction, and peer-mediated instruction and interventions. Theory suggests the practice of inclusion is congruent with social justice, but evidence suggests mixed results regarding academic achievement typically occur. However, results of providing separate pullout instructional services are not necessarily more likely to achieve desired results. Therefore, educators will need to make placement decisions considering the resources available in their school, in addition to the skill level …

Analysis Of Laser Induced Spallation Of Electron Beam Physical Vapor Deposited (Eb-Pvd) Thermal Barrier Coatings, David Allen Beeler

Browse all Theses and Dissertations

The use of thermal barrier coatings (TBCs) has been an important factor in the efficiency improvements of jet engines due to their ability to withstand the extreme environments within the engine. With this improved resistance, TBCs have also become more difficult to remove without damaging the substrate. Mound Laser & Photonics Center, Inc. (MLPC) has developed an innovative, laser based technique to spall this coating. The intention of this work was to investigate and better understand the removal mechanism. Through experimentation and analysis (such as high speed video, Scanning Electron Microscopy and Energy Dispersive Spectroscopy, semi-logarithmic analysis, and a numerical …

Heroes: Creating Classroom Environments, Presentations, And Activities That Positively Affect Student Motivation, Inclusion, And Retention, Virginia Heslinga

Electronic Journal for Inclusive Education

To help students of diverse needs learn, retain what they learn, collaborate in problem-solving, see value with inclusion, and grow in a desire to learn, teachers need to create environments conducive to active learning and filled with hope. Environments emerge from the time a student stands in the doorway of a classroom and continue through every element on display and encountered in interactions. Educators who understand they affect the environment will set the tone, present inclusively, provide meaningful activities, and do a heroic job of leading students. This article presents heroes with classic values in schools and communities through the …

Traffic Analytics Using Probabilistic Graphical Models Enhanced With Knowledge Bases, Pramod Anantharam, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

Graphical models have been successfully used to deal with uncertainty, incompleteness, and dynamism within many domains. These models built from data often ignore preexisting declarative knowledge about the domain in the form of ontologies and Linked Open Data (LOD) that is increasingly available on the web. In this paper, we present an approach to leverage such 'top-down' domain knowledge to enhance 'bottom-up' building of graphical models. Specifically, we propose three operations on the graphical model structure to enrich it with nodes, edges, and edge directions. We illustrate the enrichment process using traffic data from 511.org and declarative knowledge from ConceptNet. …

Advancing Data Reuse In Phyloinformatics Using An Ontology-Driven Semantic Web Approach, Maryam Panahiazar, Amit P. Sheth, Ajith Harshana Ranabahu, Rutger Vos, Jim Leebens-Mack

Kno.e.sis Publications

Phylogenetic analyses can resolve historical relationships among genes, organisms or higher taxa. Understanding such relationships can elucidate a wide range of biological phenomena, including, for example, the importance of gene and genome duplications in the evolution of gene function, the role of adaptation as a driver of diversification, or the evolutionary consequences of biogeographic shifts. Phyloinformaticists are developing data standards, databases and communication protocols (e.g. Application Programming Interfaces, APIs) to extend the accessibility of gene trees, species trees, and the metadata necessary to interpret these trees, thus enabling researchers across the life sciences to reuse phylogenetic knowledge. Specifically, Semantic Web …

Twitris: Socially Influenced Browsing, Ashutosh Sopan Jadhav, Wenbo Wang, Raghava Mutharaju, Pramod Anantharam, Vinh Nguyen, Amit P. Sheth, Karthik Gomadam, Meenakshi Nagarajan, Ajith Harshana Ranabahu

Kno.e.sis Publications

In this paper, we present Twitris, a semantic Web application that facilitates browsing for news and information, using social perceptions as the fulcrum. In doing so we address challenges in large scale crawling, processing of real time information, and preserving spatio-temporal-thematic properties central to observations pertaining to real time events. We extract metadata about events from Twitter and bring related news and Wikipedia articles to the user. In developing Twitris, we have used the DBPedia ontology.

The Feasibility Of Implementing The Acp-215 At The Dayton Community Blood Center: A Cost-Benefit Analysis, Angela Albrecht

Master of Public Health Program Student Publications

The community blood supply is a limited resource with a relatively short shelf-life. To ensure an adequate supply, a balance must be maintained between the numbers of donors providing blood and blood products required by hospitals to meet patient needs. Any change in the number of blood donors or in the volume of blood required by hospitals can create a blood shortage. During times of disaster, a blood shortage may be inevitable. Additional strategies must be in place to ensure availability of blood for essential transfusions across the community. Cryopreservation of red blood cells to build and maintain a blood …

Adaptive Semantic Annotation Of Entity And Concept Mentions In Text, Pablo N. Mendes

Kno.e.sis Publications

The recent years have seen an increase in interest for knowledge repositories that are useful across applications, in contrast to the creation of ad hoc or application-specific databases.
These knowledge repositories figure as a central provider of unambiguous identifiers and semantic relationships between entities. As such, these shared entity descriptions serve as a common vocabulary to exchange and organize information in different formats and for different purposes. Therefore, there has been remarkable interest in systems that are able to automatically tag textual documents with identifiers from shared knowledge repositories so that the content in those documents is described in a …

A Computational Approach To Simulating The Performance Of A 24-Hour Solar-Fuel Cell-Hydrogen Electric Power Plant, Michael K. Gustafson

Browse all Theses and Dissertations

World energy demand has risen from about 375 exajoules (EJ) in 1990 to around 600 EJ today. The Energy Information Administration predicts that by the year 2035, this figure will rise to around 800 EJ. This places large stresses on the electric generation infrastructure. Increasingly this demand is being met by renewable energy sources. There are several reasons this is the case. The prices of renewables are dropping quickly and reaching grid parity in more regions. Utilizing renewable energy generation can help achieve energy security: adverse weather or military conflicts are less likely to impact supply routes when energy is …

The Effects Of Stereoscopic Radar Displays On Air Traffic Controller Performance, Jason G. Russi, Brent T. Langhals, Michael E. Miller, Eric Heft

International Symposium on Aviation Psychology - 2013

Controllers identify vertical separation in aircraft depicted on 2-D radar displays by calculating altitude from numerical values. This is used to create a 3-D mental image to determine vertical spacing; a mentally fatiguing practice. Current stereoscopic display technology exists that may allow reduction of this aspect of controller workload. With a near doubling of traffic expected within the next two decades (FAA, 2012), controllers’ abilities to rapidly interpret spacing and maintain awareness will become increasingly imperative to safety. A stereoscopic radar simulator was developed and field-tested with 35 USAF controllers. It presented a top-down view, similar to traditional radar displays, …

Exploring The Effects Of Working Memory Capacity, Attention, And Expertise On Situation Awareness In A Flight Simulation Environment, Orçun Orkan Özcan, Murat Perit Çakır, Bilge Say

International Symposium on Aviation Psychology - 2013

Simulator pilots are subject to some of the constraints of a real flight situation in a PC based flight simulation. Situation awareness (SA) for simulator pilots was explored in terms of underlying cognitive aspects by analyzing the compound effects of expertise, working memory, inhibition and divided attention. Online and Offline SA measurements were analyzed with expertise and scores of Automated Operation Span Task, Stroop and Coşkunöz visual attention tasks. Regression analyses revealed the expected relationships of simulator pilots’ SA with expertise and inhibition capacity but not with working memory and divided attention capacity. Obtained results were also compared to those …

Synthesis And Characterization Of Graphene Oxide/Sulfur Nanocomposite For Lithium-Ion Batteries, Aaron Joseph Blake

Browse all Theses and Dissertations

The growing need for clean and efficient energy storage systems has recently peaked due to concerns of climate change and increased global energy consumption. However, efficiently integrating renewable resources such as solar and wind energy into society will require a complex electrical energy storage (EES) system capable of storing and expending significant amounts of energy. A battery based on the lithium/sulfur couple can yield a theoretical specific energy of 2600Wh/kg, which is about five times higher than that offered by present Li-ion batteries, and hence, is a promising and attractive technology. Despite recent developments in addressing various issues inherent to …

Extending Positive Class Results Across Multiple Instructors And Multiple Classes Of Modeling Instruction, Eric Brewe, Adrienne L. Traxler, Jorge De La Garza, Laird H. Kramer

Physics Faculty Publications

We report on a multiyear study of student attitudes measured with the Colorado Learning Attitudes about Science Survey in calculus-based introductory physics taught with the Modeling Instruction curriculum. We find that five of six instructors and eight of nine sections using Modeling Instruction showed significantly improved attitudes from pre- to postcourse. Cohen’s d effect sizes range from 0.08 to 0.95 for individual instructors. The average effect was d = 0.45, with a 95% confidence interval of (0.26–0.64). These results build on previously published results showing positive shifts in attitudes from Modeling Instruction classes. We interpret these data in light …

Consequence Based Procedure For Description Logics With Self Restriction, Cong Wang, Pascal Hitzler

We present a consequence based classification procedure for the description logics with self restriction constructor. Due to the difficulty of constructing a concept inclusion model for self restriction, we use a different proof by showing that all the completion rules can simulate all the corresponding ordered resolution inferences.

Model For Thickness Dependence Of Mobility And Concentration In Highly Conductive Zinc Oxide, David C. Look, T. C. Droubay, S. A. Chambers

Physics Faculty Publications

The dependences of the 294 and 10 K mobility μ and volume carrier concentration n on thickness (d=25 to 147 nm) are examined in aluminum-doped zinc oxide (AZO). Two AZO layers are grown at each thickness, one with and one without a 20-nm-thick ZnON buffer layer. Plots of the 10 K sheet concentration ns versus d for buffered (B) and unbuffered (UB) samples give straight lines of similar slope, n=8.36×1020 and 8.32×1020  cm−3, but different x-axis intercepts, δd=−4 and +13  nm, respectively. Plots of ns versus d at 294 K produce substantially the same results. Plots of μ versus d …

Compensation In Al-Doped Zno By Al-Related Acceptor Complexes: Synchrotron X-Ray Absorption Spectroscopy And Theory, Jiraroj T-Thienprasert, S. Rujirawat, W. Klysubun, J. N. Duenow, T. J. Coutts, S. B. Zhang, David C. Look, Sukit Limpijumnong

Physics Faculty Publications

The synchrotron x-ray absorption near edge structures (XANES) technique was used in conjunction with first-principles calculations to characterize Al-doped ZnO films. Standard characterizations revealed that the amount of carrier concentration and mobility depend on the growth conditions, i.e. H₂ (or  O₂)/Ar gas ratio and Al concentration. First-principles calculations showed that Al energetically prefers to substitute on the Zn site, forming a donor Al_Zn, over being an interstitial (Al_i). The measured Al K-edge XANES spectra are in good agreement with the simulated spectra of Al_Zn, indicating that the majority of Al atoms …

Secondary Teachers’ Knowledge Of Response To Intervention, Cherry M. Stanard Ed.S., Ravic P. Ringlaben, Kimberly Griffith Ph. D.

Electronic Journal for Inclusive Education

School systems across the United States have been required by federal laws to utilize scientific based interventions and instruction within the classroom to educate all students. Through the use of a multi-tiered model called Response to Intervention (RTI), school systems now have a model to implement the interventions within the environment. The purpose of this study was to investigate secondary teachers’ knowledge of RTI within a public school system in the southeastern United States. It is vital that the teachers and specialists who implement RTI be knowledgeable of the multi-tiered model. The teacher’s knowledge of RTI can help guide administrators …

Logical Linked Data Compression, Amit Krishna Joshi, Pascal Hitzler, Guozhu Dong

Computer Science and Engineering Faculty Publications

Linked data has experienced accelerated growth in recent years. With the continuing proliferation of structured data, demand for RDF compression is becoming increasingly important. In this study, we introduce a novel lossless compression technique for RDF datasets, called Rule Based Compression (RB Compression) that compresses datasets by generating a set of new logical rules from the dataset and removing triples that can be inferred from these rules. Unlike other compression techniques, our approach not only takes advantage of syntactic verbosity and data redundancy but also utilizes semantic associations present in the RDF graph. Depending on the nature of the dataset, …

Effects Of Endothelial Progenitor Cell-Derived Microvesicles On Hypoxia/Reoxygenation-Induced Endothelial Dysfunction And Apoptosis, Jinju Wang, Shuzhen Chen, Xioatang Ma, Chuanfang Cheng, Xiang Xiao, Ji Chen, Shiming Liu, Bin Zhao, Yanfang Chen

Pharmacology and Toxicology Faculty Publications

Oxidative stress-induced endothelial dysfunction plays a key role in ischemia/reperfusion injury. Recent evidence indicates that endothelial progenitor cell-derived microvesicles (EPC-MVs) can promote angiogenesis of endothelial cells (ECs). Here, we investigated the potential effects of EPC-MVs on hypoxia/reoxygenation (H/R) injury in human brain microvascular ECs (hb-ECs). MVs were prepared from EPCs cultured in a serum deprivation (SD) medium (starving stress, sEPC-MVs) or SD medium containing tumor necrosis factor-α (TNFα) (apoptotic stress, aEPC-MVs). H/R injury model of hb-ECs was produced by 6 hr hypoxia (1% O₂) and 24 hr reoxygenation. The H/R hb-ECs were co-cultured with EPC-MVs. Results showed that …

A Geophysical Investigation To Locate Missing Graves Utilizing Ground Penetrating Radar, Electromagnetic, And Magnetic Methods, Jared Wyatt Shank

Browse all Theses and Dissertations

Old cemeteries often have graves that are unmarked because gravestones are missing or degraded and the graves are in areas for which maps or other historical documents are incomplete. This is the case for one cemetery in southwestern Ohio, known as Stevenson Cemetery, which contains graves of Revolutionary War and War of 1812 veterans. The immediate goal of this study is to locate unmarked graves in this cemetery using geophysical techniques. The broader goal is to evaluate three geophysical techniques to determine the effectiveness of each.

The three geophysical techniques evaluated in this study are magnetics, electro-magnetics, and ground-penetrating radar. …

The design consists of a 16-bit phase accumulator, a set of 18 band pass finite impulse response filters, a 12-bit digital to analog converter and a low pass filter to produce a sine wave with output frequencies ranging from 36 MHz to 72 MHz with a resolution of 3.05 kHz and a 55 dB spur free dynamic range. The same hardware can be used to achieve …

The Synthesis And Characterization Of 1,3-Bisphenylsulfonylacetone, 2,5-Dicarboethoxy-3,4-Di(4-Methylphenyl)Cyclopentadienone Dimer, And Dp-Ppv Polymers And Oligomers, Mark Robert Duffy

Browse all Theses and Dissertations

An SN2 reaction between 1,3-dichloroacetone and benzenesulfinic acid sodium salt was carried out to produce 1,3-bis(phenylsulfonyl)acetone. A crystal structure for 1,3-bis(phenylsulfonyl)acetone was obtained. The SN2 reaction was followed by a condensation reaction with benzil but this did not yield a condensation product. A photo-active compound, 2,5-dicarboethoxy-3,4-di(4-methylphenyl)cyclopentadienone, was synthesized and was shown to undergo a unique, solid-state dimerization. Several reactions involving the ester functions were carried out but these did not yield the expected products, instead, structural rearrangements seemed to predominate. An asymmetric cyclopentadienone, 2-carbomethoxy-5-methyl-3,4-diphenylcyclopentadienone, was synthesized and it was reacted with norbornadiene to produce methyl 4-methyl-2,3-diphenylbenzoate. The benzoate was reduced …
