Improved Modeling And Verification Of Metrology On Small Radius Optics, Reem Alsalamah
Improved Modeling And Verification Of Metrology On Small Radius Optics, Reem Alsalamah
Dissertations
This dissertation employs a graphical method of laser beam propagation analysis, the yybar diagram, to develop analytical solutions for a difficult optical metrology challenge: modeling of the behaviour of an interferometric system when testing small radius objects. The method presented utilizes the yybar diagram for Gaussian beams to model interferometric systems. The method enables rapid, intuitive layout and understanding of the complex properties of beam propagation, yielding algebraic calculations producing quantitative results. We first derive a relation for minimum test radius; the smallest radius part that can produce a perfect fluffed fringe, wherein the test and reference waves are identical …
Ultrafast Time-Frequency Spectroscopy Based On Few-Cycle Pump-Probe Transient Reflectometry, Hemang Jani

Journal of Law, Technology, & the Internet
Algorithmic consumer credit scoring has caused anxiety among scholars and policy makers. After a significant legislative effort by the European Union, the General Data Protection Regulation (GDPR) that has provisions tailored to automated decision-making (ADM) was implemented. When the EU Commission and the US Department of Commerce negotiated for US organizations to whom data from EU data controller is transferred to comply with the key principles of EU Data Protection Law under the EU-US Privacy Shield (PS) Framework, the Department of Commerce refused to incorporate the GDPR principles governing ADM in the PS Framework. The EU Commission accepted this refusal …

Quantum Machine Learning: A Patent Review, Brian S. Haney
Journal of Law, Technology, & the Internet
One of the central problems bottlenecking machine learning research is classical computational power limits. Quantum computing provides a solution, offering more processing power for less electric cost. Quantum Machine Learning (QML) is a research field at the intersection of quantum computing and machine learning technologies, driving the cutting edge in technological innovation. While the legal literature on software patents is rapidly scaling, the research focused on QML patents is noticeably nascent. As such, this Article contributes the first empirical patent survey for QML technologies.

Confirmatory Factor Analysis Of The Wisc-Iv With A Trinidad Referred Sample, Cherisse Rambarose
Open Access Dissertations
There has been an extensive amount of research in the intelligence-assessment literature on the structure of the Wechsler Intelligence Scale for Children, fourth edition (WISC-IV; 2003a). Numerous studies show that the test’s general factor structure replicates across normative and referred groups, in the U.S. and globally. Thus far, few studies have been done examining the factor structure of this, and other intelligence tests with Caribbean samples. The current study adds to this body of literature by examining the factor structure of the WISC-IV with a referred sample from Trinidad. This study utilized archival data from a sample accessed through private …
Help Seeking After Campus Sexual Assault: From Policy To Victims, Kathleen Ratajczak
Help Seeking After Campus Sexual Assault: From Policy To Victims, Kathleen Ratajczak
Theses and Dissertations--Sociology
Help seeking after an experience of campus sexual assault is an important link for many survivors towards processing and healing. College campuses have a plethora of resources available, from free counseling, health clinics, advocates, and reporting options all right on their doorstep. Yet many students do not seek help from these offices. This study sought to find out why by looking beyond the victim, and examining the relationship between Title IX policy, professionals who provide resources, and victims. Through both policy analysis and in-depth interviews with both professionals and victims, this study found that Title IX policy codify the social …

Teacher Knowledge Of Attention-Deficit/Hyperactivity Disorder And Classroom Management, Sarah J. Bolinger, Dr. Winnie Mucherah, Dr. Andrew M. Markelz
Teacher Knowledge Of Attention-Deficit/Hyperactivity Disorder And Classroom Management, Sarah J. Bolinger, Dr. Winnie Mucherah, Dr. Andrew M. Markelz
The Journal of Special Education Apprenticeship
There is limited research on teacher knowledge of Attention Deficit Hyperactivity Disorder (ADHD) and classroom management; however, research suggests that teacher knowledge of ADHD influences teaching behaviors. This study investigates general education teachers’ and special education teachers’ knowledge of ADHD and the interaction with classroom management. In this study, 17 teachers responded to surveys about knowledge of ADHD and classroom management. Teachers scored an average of 61% on the knowledge of ADHD questionnaire. Contrary to the hypothesis, teacher knowledge of ADHD was not significantly related to classroom management. The relationship between knowledge of ADHD and classroom management needs further examination …
Data-Driven Personalized Applications In Networks, Chuankai An
Data-Driven Personalized Applications In Networks, Chuankai An
Dartmouth College Ph.D Dissertations
A network models relationships. For a network that either encodes or supports internal information sharing activities, a better understanding of the network may enable data-driven applications (e.g., social network based recommendation), and boost both descriptive and predictive modeling of information flow in itself. In a multi-faceted manner, we propose in this thesis to contribute to several challenges that arise in the development of personalized applications in the general area of information and networks: 1) articulation of new patterns (and associated metrics) for individual user behavior and network structure; 2) exploitation of new forms of feature vector representations derived from large …
Stylized 2d Fabrication Of Non-Photorealistic Images, Athina Panotopoulou
Stylized 2d Fabrication Of Non-Photorealistic Images, Athina Panotopoulou
Dartmouth College Ph.D Dissertations
A current trend in computer graphics is the use of programmable tools that allow non-experts to engage in the design of physical prototypes. Within fabrication, one area of research focuses on non-photorealistic images which are stylized to depict a particular aesthetic quality or convey key information. In cases where authenticity is demanded or the images need to be manipulated, fabrication is necessary. Non-photorealistic image fabrication involves two challenges: identifying and abstracting key information during design and considering material restrictions during fabrication. This thesis showcases two examples for fabricating new types of non-photorealistic images, the first involving watercolors, and the second …

Intersections Of Deleted Digits Cantor Sets With Gaussian Integer Bases, Vincent T. Shaw
Browse all Theses and Dissertations
In this paper, the intersections of deleted digits Cantor sets and their fractal dimensions were analyzed. Previously, it had been shown that for any dimension between 0 and the dimension of the given deleted digits Cantor set of the real number line, a translate of the set could be constructed such that the intersection of the set with the translate would have this dimension. Here, we consider deleted digits Cantor sets of the complex plane with Gaussian integer bases and show that the result still holds.

Hierarchical Hybrid Materials From Flexible Fabric Substrates, Wenhu Wang
Browse all Theses and Dissertations
The goal of this project is to investigate fabrication approaches and structure-property relationships of porous and flexible hierarchical hybrid solids suitable for advanced surface-active devices. Multi-scale hierarchical carbon materials are being fabricated by strong covalent attachment of multiwall carbon nanotube(MWCNTs) arrays on flexible carbon fabric substrates in order to enhance the surface area per unit volume. This was done using chemical vapor deposition (CVD) after functionalizing the surface with a plasma-derived nano-oxide coating. Structural and chemical characterization is performed using scanning electron microscope(SEM), energy dispersive spectroscopy(EDS) and x-ray photoelectron spectroscopy(XPS). Surface area estimates have been made by building structural models …

Introducing Functionality To Poly(Arylene Ether)S Via Modification Of Diphenyl Sulfone – Type Monomers, Zahida Humayun
Browse all Theses and Dissertations
The synthesis of poly(arylene ether)s, with a pendent aryl iodide, was achieved via nucleophilic aromatic substitution (NAS) polycondensation of DI-DFDPS monomer. The platform diiodo-difluorodiphenyl sulfone monomer, DFDPS-DI (3), was prepared in one-step, via EAS chemistry. Structural characterization was provided by NMR spectroscopy, GC/MS, and elemental analysis. As “pre” approach didn’t work here, so “post” approach was used to synthesize N-heterocycle functionalized copolymers. The DI-copolymers were subjected to copper-catalyzed C-N coupling reaction with carbazole, phenoxazine, and indole and the syntheses of chromophore based copolymer were successfully carried out. A series of PAEs containing carbazole, phenoxazine, and indole substituents were synthesized and …

Browse all Theses and Dissertations
In the last decade, the advent of social media and microblogging services have inevitably changed our world. These services produce vast amounts of streaming data, and one of the most important ways of analyzing and discovering interesting trends in the streaming data is through clustering. In clustering streaming data, it is desirable to perform a single pass over incoming data, such that we do not need to process old data again, and the clustering model should evolve over time not to lose any important feature statistics of the data. In this research, we have developed a new clustering system that …

One of the strategies for reducing the emission of the greenhouse gas carbon dioxide (CO2) and mitigating its accumulation into the Earth’s atmosphere is geologic sequestration (GSCO2). This process might be paired with enhanced oil recovery (EOR) within depleted oil reservoirs to provide an economic incentive for GSCO2. Heterogeneity within reservoirs (e.g. spatial differences in entry pressure, permeability, and porosity) can exert significant influence on the dynamics of fluid flow during EOR and GSCO2, and thus on the ultimate success of GSCO2-EOR. The Western Belt sandstones of the Cypress Formation in the Illinois Basin are candidate reservoirs for GSCO2-EOR. Heterogeneity …

Browse all Theses and Dissertations
At the present time, using wind and solar energy for producing electricity in the United States is becoming cost competitive. According to Lazard’s 2019 [36] levelized cost of energy (LCOE) analysis of a number of energy sources used for producing electricity in the United States, wind and solar are cheaper than natural gas and coal. While capital, maintenance, operation, and fuel costs are included in LCOE numbers, energy source intermittency is not. Intermittency is an important issue with wind and solar energy sources, but not with natural gas or coal energy sources. Combining wind and solar energy sources into one …
