Caiden: The Communications System, Jennifer Case

Honors Capstones

CAIDEN is a mobile robotic platform that can be equipped with a number of various sensors for specified use. A communication system was developed to convey commands and data to the robot. XBees were used to obtain wireless communication between the user and the robot. The communication system consisted of both intra- and interrobotic communication. Within the robot, there are a variety of sensors and two micro-controllers that need to work together to make the robot function appropriately. Outside of the robot, there is a GUI that the operator uses to monitor and control CAIDEN's movement. This system was rigorously …

Comparative Analysis Of English Language Learners' Experiences In Public School At The Third And Eighth Grade Levels, Amanda Lenox, Kristin Liewald

Honors Capstones

The field of education is one that endeavors constant change of fluctuating degrees. Most recently and drastically, the educational field has experienced and responded to changes in the cultural and linguistic diversity that is rapidly increasing in classrooms across the United States. Congruently, current legislation holds both educators and students accountable for their standardized performance and accomplishments, although teachers of ethnically diverse students are not required to be certified in the teaching of these learners. As a result, it was the purpose of this study to identify and analyze the themes evident from a series of observations and interviews conducted …

The Ishraq Program For Out-Of-School Girls: From Pilot To Scale-Up, Mona Selim, Nahla G. Abdel-Tawab, Khaled El Sayed, Asmaa Elbadawy, Heba El Kalaawy

Poverty, Gender, and Youth

In response to the needs of adolescent girls in Egypt for improved schooling, health, and livelihood prospects, Ishraq (sunrise)—a multidimensional program for 12–15-year-old out-of-school girls—was launched in 2001 by the Population Council in collaboration with CEDPA, Save the Children, Caritas, and local nongovernmental organizations. The program combined traditional tested program elements (literacy, life skills, nutrition) with more innovative ones (sports, financial education). It focused on building a multilayered platform to support and institutionalize the program by educating and mobilizing communities around issues of importance to adolescent girls; forging partnerships between international NGOs, government institutions, and local NGOs; and building capacities …

Smooth Local Subspace Projection For Nonlinear Noise Reduction, David Chelidze

Mechanical, Industrial & Systems Engineering Faculty Publications

Many nonlinear or chaotic time series exhibit an innate broad spectrum, which makes noise reduction difficult. Local projective noise reduction is one of the most effective tools. It is based on proper orthogonal decomposition (POD) and works for both map-like and continuously sampled time series. However, POD only looks at geometrical or topological properties of data and does not take into account the temporal characteristics of time series. Here, we present a new smooth projective noise reduction method. It uses smooth orthogonal decomposition (SOD) of bundles of reconstructed short-time trajectory strands to identify smooth local subspaces. Restricting trajectories to these …

Dynamics Of Nonhomogeneous Carbon Steel Plates, J. H. Kim, L. Zhang, R. Hebert, J. T. Wright, A. Shukla

Mechanical, Industrial & Systems Engineering Faculty Publications

This paper presents finite element modeling procedure for rate-dependent elastic-plastic nonhomogeneous carbon steel plates subjected to dynamic loads. The steel plate consists of two ductile materials. We utilize a modified rule of mixture and linear strain-rate dependence to derive constitutive relations which are then implemented in ABAQUS/Explicit through user subroutine. Validation of the developed procedure is partially made with Steel 1018. Comparative numerical study is done between Steel 1018 and the nonhomogeneous plate. Displacements, stresses and relevant energy terms are calculated and compared for various sets of material configurations. © Published under licence by IOP Publishing Ltd.

Eigenfunction Expansions Associated With The One-Dimensional Schrödinger Operator, Daphne Gilbert

Articles

We consider the form of eigenfunction expansions associated with the time-independent Schrödinger operator on the line, under the assumption that the limit point case holds at both of the infinite endpoints. It is well known that in this situation the multiplicity of the operator may be one or two, depending on properties of the potential function. Moreover, for values of the spectral parameter in the upper half complex plane, there exist Weyl solutions associated with the restrictions of the operator to the negative and positive half-lines respectively, together with corresponding Titchmarsh-Weyl functions.

Applications Of Fourier Analysis To Audio Signal Processing: An Investigation Of Chord Detection Algorithms, Nathan Lenssen

CMC Senior Theses

The discrete Fourier transform has become an essential tool in the analysis of digital signals. Applications have become widespread since the discovery of the Fast Fourier Transform and the rise of personal computers. The field of digital signal processing is an exciting intersection of mathematics, statistics, and electrical engineering. In this study we aim to gain understanding of the mathematics behind algorithms that can extract chord information from recorded music. We investigate basic music theory, introduce and derive the discrete Fourier transform, and apply Fourier analysis to audio files to extract spectral data.

Second Order Approximations In Sequential Point Estimation Of The Probability Of Zero In Poisson Distribution, Eisa Mahmoudi, Mohammad Hatami Kamin

Turkish Journal of Mathematics

In the analysis of the count data, the Poisson model becomes overtly restrictive in the case of over-dispersed or under-dispersed data. When count data are under-dispersed, specific models such as generalized linear models (GLM) are proposed. Other examples are the zero-inflated Poisson model (ZIP) and zero-truncated Poisson model (ZTP), which have been used in literature to deal with an excess or absence of zeros in count data. Thus having a knowledge of the probability of zeros and its estimation in Poisson distribution can be significant and useful. Some estimation problems with unknown parameter cannot attain minimum risk where the sample …

Application Of Swarm And Reinforcement Learning Techniques To Requirements Tracing, Hakim Sultanov

Theses and Dissertations--Computer Science

Today, software has become deeply woven into the fabric of our lives. The quality of the software we depend on needs to be ensured at every phase of the Software Development Life Cycle (SDLC). An analyst uses the requirements engineering process to gather and analyze system requirements in the early stages of the SDLC. An undetected problem at the beginning of the project can carry all the way through to the deployed product.

The Requirements Traceability Matrix (RTM) serves as a tool to demonstrate how requirements are addressed by the design and implementation elements throughout the entire software development lifecycle. …

Automatic Detection Of Abnormal Behavior In Computing Systems, James Frank Roberts

Theses and Dissertations--Computer Science

I present RAACD, a software suite that detects misbehaving computers in large computing systems and presents information about those machines to the system administrator. I build this system using preexisting anomaly detection techniques. I evaluate my methods using simple synthesized data, real data containing coerced abnormal behavior, and real data containing naturally occurring abnormal behavior. I find that the system adequately detects abnormal behavior and significantly reduces the amount of uninteresting computer health data presented to a system administrator.

Automatic Performance Level Assessment In Minimally Invasive Surgery Using Coordinated Sensors And Composite Metrics, Sami Taha Abu Snaineh

Theses and Dissertations--Computer Science

Skills assessment in Minimally Invasive Surgery (MIS) has been a challenge for training centers for a long time. The emerging maturity of camera-based systems has the potential to transform problems into solutions in many different areas, including MIS. The current evaluation techniques for assessing the performance of surgeons and trainees are direct observation, global assessments, and checklists. These techniques are mostly subjective and can, therefore, involve a margin of bias.

The current automated approaches are all implemented using mechanical or electromagnetic sensors, which suffer limitations and influence the surgeon’s motion. Thus, evaluating the skills of the MIS surgeons and trainees …

Recovering Local Neural Tract Directions And Reconstructing Neural Pathways In High Angular Resolution Diffusion Mri, Ning Cao

Theses and Dissertations--Computer Science

Magnetic resonance imaging (MRI) is an imaging technique to visualize internal structures of the body. Diffusion MRI is an MRI modality that measures overall diffusion effect of molecules in vivo and non-invasively. Diffusion tensor imaging (DTI) is an extended technique of diffusion MRI. The major application of DTI is to measure the location, orientation and anisotropy of fiber tracts in white matter. It enables non-invasive investigation of major neural pathways of human brain, namely tractography. As spatial resolution of MRI is limited, it is possible that there are multiple fiber bundles within the same voxel. However, diffusion tensor model is …

Context Aware Privacy Preserving Clustering And Classification, Nirmal Thapa

Theses and Dissertations--Computer Science

Data are valuable assets to any organizations or individuals. Data are sources of useful information which is a big part of decision making. All sectors have potential to benefit from having information. Commerce, health, and research are some of the fields that have benefited from data. On the other hand, the availability of the data makes it easy for anyone to exploit the data, which in many cases are private confidential data. It is necessary to preserve the confidentiality of the data. We study two categories of privacy: Data Value Hiding and Data Pattern Hiding. Privacy is a huge concern …

A Novel Computational Framework For Transcriptome Analysis With Rna-Seq Data, Yin Hu

Theses and Dissertations--Computer Science

The advance of high-throughput sequencing technologies and their application on mRNA transcriptome sequencing (RNA-seq) have enabled comprehensive and unbiased profiling of the landscape of transcription in a cell. In order to address the current limitation of analyzing accuracy and scalability in transcriptome analysis, a novel computational framework has been developed on large-scale RNA-seq datasets with no dependence on transcript annotations. Directly from raw reads, a probabilistic approach is first applied to infer the best transcript fragment alignments from paired-end reads. Empowered by the identification of alternative splicing modules, this framework then performs precise and efficient differential analysis at automatically detected …

Whose Choice Are We Talking About: The Exclusion Of Students With Disabilities From For-Profit Online Charter Schools, Matthew D. Bernstein

Richmond Public Interest Law Review

By examining the history of special education law against the emergence of the for-profit and online education movements, this paper explores the charter school movement from a consumer law perspective. It aims to explain why much of the current debate over test scores, "accountability," and teacher evaluation obscures other systemic fault lines that implicate the very reasons we have a public education system in the first place. In turn, the goal is to suggest solutions to some fundamental questions: in the twenty-first century, do we still need a public education system? What are our collective responsibilities to students? What does …

The Contribution Of Social Simulation In The Advancement Of Marketing Issues And Challenges, Mario V. González Fuentes

School of Business Faculty Research

For some years now, marketers have been praising for a more holistic approach of a company’s marketing efforts across all areas. However, traditional models show serious limitations to address the complexities of managing all of a company’s touch points with a customer. Agent-based modeling (ABM) has opened the door to explore the unfolding behaviors and outputs of an increasingly connected and interactive marketplace. The contribution of this paper is twofold. On the one hand, it provides researchers with a state-of-the-art repository for this strand of research. This facilitates the identification of relevant gaps in the literature and future research avenues. …
