Effects Of Computer Assisted Tier Ii Interventions By Gender On Math And Reading Achievement For Remediated Students, Kathi (Lutz) Sweere

College of Education Dissertations

Response to Intervention (RtI) is a current reform initiative being examined by educators, politicians, and proponents of differentiated education. RtI has tiers of intervention designed to meet the various academic needs of all students. RtI has been developed as an educational methodology to increase student achievement through various problem-solving techniques, through the implementation of specific interventions based on each student’s individual needs, and through data-based decision making regarding the interventions used. The implementation of RtI requires schools to shift current educational paradigms of how services are delivered to students.

This quantitative causal comparative study compared the effectiveness of PLATO alone, …

Finding Unpredictable Behaviors Of Periodic Bouncing For Forced Nonlinear Spring Systems When Oscillating Time Is Large, Yanyue Ning

Honors Scholar Theses

The model of nonlinear spring systems can be applied to deal with different aspect of mechanical problems, such as oscillations in periodic flexing in bridges and ships. The concentration of this research is the bouncing behaviors of nonlinear spring system when the processing time is large, therefore nonlinear ordinary differential equations (ODE) are suitable since researchers can add different variables into the models and solve them by computational methods. Benefit from this, it is easy to check the oscillations or bouncing behaviors that each variable contributes to the model and find the relationship between some important factors: vibrating frequency, external …

Best Practices To Make Online Learning An Advantageous Tool For Students With Specific Learning Disorder, Sanchi Kalra

Intersections Fall 2020

Online education has been prevalent for years, but with the spread of the Covid-19, it became the most viable option for students all over the world. Out of these students, an estimated 15-20% of them show signs of what the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders describes as Specific Learning Disorder (SLD). Students with SLD experience difficulties with learning and using academic skills such as reading, writing, and mathematics. These difficulties are independent of intelligence. Over the past two decades, SLD has also been referred to as dyslexia or a learning disability. While adapting to …

Remarkable Sensitivity Of The Prospective Photodynamic Therapy Agent 6-Selenoguanine To Ph, Collin Merrick, Sean J. Hoehn, Luis A. Ortiz-Rodríguez, Sarah Krul, Carlos E. Crespo-Hernández

Intersections Fall 2020

The photophysical properties of the canonical DNA/RNA nucleobases can be modified by selective functionalization. The carbonyl functional group at the C6 position of guanine or 2-amino-6-oxopurine, for example, can be removed to form 2-aminopurine, thus replacing the ultrafast internal conversion pathway to the ground state observed in guanine with slow internal conversion and intersystem crossing pathways in 2-aminopurine.1 Similarly, substitution of the carbonyl oxygen in guanine with a heavier atom results in a redshift of the absorption spectrum and a remarkable modulation of the electronic relaxation pathways of the DNA nucleobase. More specifically, sulfur substitution redshifts the absorption spectrum of …

Charge Transport Properties Of Bo-Chelated Azadipyrromethenes, Tingrui Ma, Muyuan Zhao, Geneviève Sauvé

Intersections Fall 2020

Intramolecular BO-chelated azadipyrromethenes are promising organic semiconductors. Here, we evaluated the electron and hole mobility of a series of BO-chelated azadipyrromethenes using the Space Charge Limited Current(SCLC) method. In order to determine the mobility of the material, Mott Gurney's law was applied using the film thickness and slope of the J1/2 versus voltage plot in the SCLC graph. The best electron mobility observed for BO-chelated materials is 4.64—10-6 cm2V-1s-1 and the best hole mobility is 7.38—10-4 cm2V-1s-1. These results suggest that BO-chelated materials are promising p-type semiconductors for electronic applications.

On The Behavior Of The Gamma Function On The Negative Side, Tri Minh Ngo

Senior Honors Theses

In this paper we analyze the behavior of the Gamma function at its critical points and points of discontinuity on the negative side of the x-axis. We will also explain the bluntness of the gamma function on this negative side.

Safe: Simulation Automation Framework For Experiments, Luiz Felipe Perrone, Bryan C. Ward, Christopher S. Main

Faculty Journal Articles

The workflow of a network simulation study requires adherence to best practices in methodology so that results are credible and reproducible by third parties. The opportunities for one to introduce errors start at model description and permeate the process through to the reporting of results. The literature indicates that even publications in respected venues include inadvertent mistakes and poor application of methodology. When experts are liable to fail, it is unreasonable to expect that students would fare any better. This paper presents a system designed to provide guidance for inexperienced users of the popular ns-3 network simulator. SAFE automates the …

Methods For Speculatively Bootstrapping Better Intrusion Detection System Performance, Sunny Fugate

Computer Science ETDs

During the last three decades, the designers of computer IDSs have been continuously challenged with performance bottlenecks and scalability issues. The number of threats is enormous. The performance of ID systems depends primarily on the quantity of input data and complexity of detected patterns. During noisy attacks, system load tends to increase proportional to increasing data rates, making ID systems vulnerable to flooding and denial-of-service attacks. Unfortunately, the number, type, and sophistication of threats is quickly increasing, outpacing our ability to detect them. The more we try to detect, the more computing and economic resources must be reserved solely for …

Multivalent Random Walkers:A Computational Model Of Superdiffusive Transport At The Nanoscale, Mark Joseph Olah

Computer Science ETDs

We present a stochastic model and numerical simulation framework for a synthetic nanoscale walker that can be used to transport materials and information at superdiffusive rates in artificial molecular systems. Our \emph{multivalent random walker} model describes the motion of a walker with a rigid, inert body and flexible, enzymatic legs. A leg can bind to and irreversibly modify surface-bound chemical substrate sites arranged as nanoscale tracks. As the legs attach to, modify, and detach from the sites, the walker moves along these tracks. Walkers are symmetrical and the tracks they walk on are unoriented, yet we show that under appropriate …

An Examination Of Physical And Empirical Approaches In Forecasting Nonconvective Wind Gusts, Jeramie Lippman

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Nonconvective winds can be a dangerous and costly weather hazard. For example, over a ten year span from 2002 to 2011, there were over 200 fatalities and nearly 1,000 injuries, as well as over 6.4 billion dollars in monetary losses due to high, nonconvective winds. An important subset to nonconvective winds is the nonconvective wind gust. When winds are already relatively strong, a sudden wind gust can magnify already existing hazards. Three different methods were evaluated to determine if either of two physically based algorithms can outperform an empirical algorithm. The two physically based methods were the Wind Gust Estimate …

Which Study Method Works Best? A Comparison Of Soar And Sq3r For Text Learning, Sarah C. Kasson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

One hundred thirty-eight college students participated in a study comparing the SOAR (Select, Organize, Association, Regulate) and SQ3R (Survey, Question, Read, Recite, Review) study systems to each other and to students’ preferred study methods. Though both systems have been researched independently, just one other study has compared these study systems to each other. College students were assigned randomly to one cell of a 2x2 factorial design (method: SOAR or SQ3R; material: supplement or no supplement) or to a preferred-study-method control group. Groups were trained in their respective system (SOAR, SQ3R, or control) and then given materials about educational measurement to …

In-Plane Shear Resistance Of Sustainable Structural Walls With Large Openings, Matija Radovic

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

Shear walls are primary structural systems that support building against lateral loads (tornadoes and hurricanes). Even though concrete shear walls are the most efficient lateral resisting system, they are rarely used in a residential construction. The reasons for why contractors do not use concrete walls in residential construction were due to higher construction cost and slower construction paces. This study proposes building and testing residential concrete structural wall system that is energy efficient, cost competitive and structurally safe.

In order to decrease environmental impact of the residential construction process, this study proposed implementing sustainability concept while building residential structures. The …

Morphometric, Biochemical, And Raman Spctral Analyses Of Muscle Damage In Patients With Peripheral Arterial Disease: Provising Objective Criteria For Diagnosis And Treatment Monitoring, Kim Cluff

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Peripheral arterial disease (PAD), which affects approximately 10 million Americans, is characterized by atherosclerosis of the non-coronary arteries. PAD produces a progressive accumulation of ischemic injury to the limbs that is reflected in a gradual worsening in the myofiber morphology and oxidative damage in the gastrocnemius muscle. In this study, we evaluated the hypothesis that quantitative morphological and biochemical parameters of gastrocnemius myofibers change in a consistent manner during the progression of PAD, provide an objective grading of muscle degeneration in the ischemic limb, and correlate to clinical stage of PAD. Myofiber morphometrics were determined precisely with mathematical equations that …

Interactions Of Zoo Plankton And Phytoplankton With Cyanobacteria, Rebecca J. Alexander

School of Natural Resources: Dissertations, Theses, and Student Research

Cyanobacteria are a major concern in Nebraska reservoirs and are capable of producing toxins that can cause skin irritations and gastrointestinal problems, as well as affect the nervous system. It is important to determine the mechanisms that can cause cyanobacteria blooms due to the effect they can have on human health. The interaction of zooplankton and other phytoplankton groups with cyanobacteria is important because there is a biological component in surface waters that should be taken into consideration along with the physical and chemical parameters that have been noted to promote cyanobacteria. For example, zooplankton have the ability to alter …

The Use Of Tree Rings To Study The Impacts Of Stream Flow And Climate Variability On Native And Invasive Woody Species Along A Semi-Arid Riparian Ecosystem In The Great Plains, Usa, Kristen M. Skolaut

School of Natural Resources: Dissertations, Theses, and Student Research

Forested riparian areas of the Northern Great Plains have historically been dominated by the native Populus deltoides L. vegetation type. Changes in climate, stream flow, groundwater, and management practices in the past few decades have promoted the expansion of the upland native woody species Juniperus virginiana L. and the invasion of the non-native Elaeagnus angustifolia L. into these riparian ecosystems. This study aims at using dendrochronology, or the study of tree rings, to assess the impacts of intra- and inter- annual climatic variability and stream flow over the past decades, on the annual tree ring growth, oxygen and carbon isotopic …

Investigations Of Inter- And Intramolecular C-O Bond Forming Reactions Of Peroxide Electrophiles, Benjamin W. Puffer

Department of Chemistry: Dissertations, Theses, and Student Research

A common reaction to yield ethers relies on an alkoxide nucleophile and a carbon electrophile (Williamson ether formation). Ethers can also be formed by reactions with carbon nucleophiles and oxygen electrophiles by way of the peroxide functional group. We screened a number of carbon nucleophiles suitable for attack on dialkyl peroxides to form new C-O bonds. Also a novel approach using a peroxyketal electrophile is shown to increase the efficiency of this intermolecular reaction. This method of C-O bond formation can also be implemented intramolecularly, not seen before in the literature, to yield cyclic ethers. This approach requires the generation …

This study involved the use of questionnaires with 100 teacher candidates enrolled on an introductory course on diversity in education in a Florida university. Teacher candidates responded to a series of items to identify beliefs about giftedness within and outside the context of education as well as the value of training in gifted education for educators. Of the 100 respondents, 79% agreed or strongly agreed with the need for specialized training for educators …

Art As A Questioning Process, Elizabeth Perez

HIM 1990-2015

The topic of this thesis is, broadly, the crisis of postmodernity and the solution that French rhetorician, Michel Meyer, presents in his theory “problematology.” Meyer looks to relocate the focus of philosophical attention on the question as opposed to the answer. Meyer calls preoccupation with answers “propositionalism.” Propositionalism can be likened to the looming scientism that threatens philosophy in general. Meyer shows, through an examination of questioning, how philosophy can be rescued from obsolescence without being detracted to scientism. Although Meyer’s philosophy is promising, it could not be considered thorough if it did not address art. Using Gilles Deleuze and …

Use Of Pile Driving Analysis For Assessment Of Axial Load Capacity Of Piles, Rodrigo Salgado, Yanbei Zhang

JTRP Technical Reports

Driven piles are commonly used in foundation engineering. Pile driving formulae, which directly relate the pile set per blow to the capacity of the pile, are commonly used to decide whether an installed pile will have the designed capacity. However, existing formulae have been proposed based on empirical observations and have not been validated scientifically, so some might over-predict pile capacity, while others may be too conservative. In this report, a more advanced and realistic model developed at Purdue University for dynamic pile driving analysis was used to develop more accurate pile driving formulae. These formulae are derived for piles …

Rotor Model Updating And Validation For An Active Magnetic Bearing Based High-Speed Machining Spindle, Adam C. Wroblewski, Jerzy T. Sawicki, Alexander H. Pesch

Mechanical Engineering Faculty Publications

This paper presents an experimentally driven model updating approach to address the dynamic inaccuracy of the nominal finite element (FE) rotor model of a machining spindle supported on active magnetic bearings. Modeling error is minimized through the application of a numerical optimization algorithm to adjust appropriately selected FE model parameters. Minimizing the error of both resonance and antiresonance frequencies simultaneously accounts for rotor natural frequencies as well as for their mode shapes. Antiresonance frequencies, which are shown to heavily influence the model’s dynamic properties, are commonly disregarded in structural modeling. Evaluation of the updated rotor model is performed through comparison …

Experimental Determination Of Colburn And Friction Factors In Small Plate Heat Exchangers With High Surface Enlargement Factors, Andrew H. Pike

Masters Theses

Experiments were conducted to measure the performance of several small brazed plate heat exchangers. A test apparatus was designed and constructed that allowed for the easy switching of the plate heat exchangers, as well as having the ability to electronically monitor and record the inlet and outlet temperatures, pressures, and flow rates. The flow rates and applied electrical power were controlled electronically by the same program which recorded the data. De-ionized water was used as the heat transfer medium to reduce the uncertainty related to fluid properties.

An existing mathematical model was used to create Colburn and friction factors based …

Network Target Coordination For Design Optimization Of Decomposed Systems, Wenshan Wang

All Dissertations

A complex engineered system is often decomposed into a number of different subsystems that interact on one another and together produce results not obtainable by the subsystems alone. Effective coordination of the interdependencies shared among these subsystems is critical to fulfill the stakeholder expectations and technical requirements of the original system. The past research has shown that various coordination methods obtain different solution accuracies and exhibit different computational efficiencies when solving a decomposed system. Addressing these coordination decisions may lead to improved complex system design. This dissertation studies coordination methods through two types of decomposition structures, hierarchical, and nonhierarchical.
