Ultrafast Laser-Induced Damage Threshold Of The Optical Materials In Near Infrared Region, Yun Jo Lee

Open Access Theses

Ultrafast optics is widely used in nowadays for optical communication, tomography, remote sensing and ranging, and even fabrication methods. In order to generating the ultrafast optical signals from such applicable devices, we need to understand the threshold that the material consisting the devices can bear without any damages. Materials’ Laser-Induced Damage Thresholds (LIDT) are varying with the laser’s characteristics that irradiated onto the material and the materials’ band gap energy. Abundant journals and papers had been published with this topic, however, it was not well studied in optical communication wavelength range. In this thesis, existing widely-accepted LIDT theory will be …

Parental Perceptions Of Stem Enrichment For Young Children, Juliana Tay, Alissa Salazar, Hyeseong Lee

Department of Education Studies Graduate Student Publications

Most pre-kindergarten and kindergarten curricula are challenging and engaging, but few are strongly grounded in STEM education. In this study, the authors examined parental perception (N=55) of the influences of a Saturday STEM enrichment program in one university center on pre-kindergarten and kindergarten students and their attitudes towards STEM learning. Using survey data collected from 2013 – 2016, the authors studied parental comments about benefits, drawbacks, and memorable moments they observed from their children’s experiences during the program. These comments were analyzed qualitatively using NVivo and three main themes were developed. The themes were children’s reactions to STEM …

“What You See Is What You Get: The Artifice Of Insight”: A Conversation Between R. Luke Dubois And Anne Collins Goodyear, Anne C. Goodyear

Artl@s Bulletin

The metaphorical relationship between sight and knowledge has long been recognized: the double-entendre of “illumination” promises both light and understanding; “I see” signifies that one “gets it” intellectually. This conversation between R. Luke DuBois and Anne Collins Goodyear addresses how data accrues meaning through pictorial structures that represent it. An artist, DuBois has consistently played with conventions for depicting information visually, revealing the intersections between data and desire they represent. Reexamining the interfaces through which we view the world, DuBois and Goodyear consider what our filters threaten to hide.

Enriching And Cutting: How To Visualize Networks Thanks To Linked Open Data Platforms., Lea Saint-Raymond, Antoine Courtin

Artl@s Bulletin

Networks are developing very quickly in the social sciences, and they are beginning to emerge in art history. This paper explores the making of network visualizations, from the building of the dataset to the analysis of results. Starting from an initial corpus regarding the Parisian auction sales for modern paintings, we developed a methodology to enrich it, thanks to linked open data platforms and technologies for realigning datasets. We then call into question the visualization of networks. Although it brings about an overview of the market and allows a very close reading, the best is the enemy of the good: …

The Computer As Filter Machine: A Clustering Approach To Categorize Artworks Based On A Social Tagging Network, Stefanie Schneider, Hubertus Kohle

Artl@s Bulletin

Image catalogs containing several million reproductions of artworks still pose a costly or computationally intensive challenge if one tries to categorize them adequately, either in a manual or automatic way. Using crowdsourced annotations assigned by laypersons, this article proposes the application of a clustering algorithm to segment artworks into groups. It is shown that the resulting clusters allow for a consistent reclassification extending the traditional categories (history, genre, portrait, still life, landscape), and thus enable a finely-grained differentiation which can be used to search in and filter image inventories, among other things.

Network Analysis And Feminist Artists, Michelle Moravec

Artl@s Bulletin

This article examines the benefits and drawbacks of using social network analysis to study feminist artists’ networks. Looking at two of the author’s digital humanities projects, it explores the systemic and structural barriers that limit the utility of social network analysis for feminist artists. The first project on the social network of artist Carolee Schneemann analyzed her female circles through a correspondence network. The second project attempted to trace the circulation of feminist art manifestos in American feminist periodicals. Three factors are identified as constraining network analysis in these case studies, the lack of feminist artists’ archives, an insufficient amount …

Dry Etching With Nanoparticles: Formation Of High Aspect-Ratio Pores And Channels Using Magnetic Gold Nanoclusters, Naveen Reddy Kadasala, Mojib Saei, Gary J. Cheng, Alexander Wei

Department of Chemistry Faculty Publications

Methods for generating nanopores in substrates typically involve one or more wet-etching steps. Here a fundamentally different approach to produce nanopores in sheet substrates under dry, ambient conditions, using nanosecond-pulsed laser irradiation and magnetic gold nanoclusters (MGNCs) as the etching agents is described. Thermoplastic films (50–75 µm thickness) are coated with MGNCs then exposed to laser pulses with a coaxial magnetic field gradient, resulting in high-aspect ratio channels with tapered cross sections as characterized by confocal fluorescence tomography. The dry-etching process is applicable to a wide variety of substrates ranging from fluoropolymers to borosilicate glass, with etch rates in excess …

Theoretical Limits Of Stone Skipping, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

A simplified geometric model captures essential dynamics of stone skipping and allows easy computation of realistic stone trajectories under a variety of conditions. The model describes idealized collisions of flat, spin-stabilized stones with water, in which the water exerts sufficient reactive force on the stone to completely stall motion normal to the stone’s bottom surface. Motion parallel to the stone’s bottom surface remains unchanged. The necessary computations, including vector forces and accelerations, work and energy, algebra and trigonometry, are understandable by first year students of classical Newtonian physics. Comparison of this highly simplified theory with suitable experiments provides an interesting …

Continuity And Disruption In European Networks Of Print Production, 1550-1750, Matthew D. Lincoln

Artl@s Bulletin

Computational analysis of the potential historical professional networks inferred from surviving print impressions offers novel insight into the evolution of early modern artistic printmaking in Europe. This analysis traces a longue durée print production history that examines the changing ways in which different regional printmaking communities interacted between 1550 and 1750, highlighting the powerful impact of demographic forces and calling in to question narratives based on single key individuals or the emergence of specific national schools.

A Multi-Paradigm Framework To Assess The Impacts Of Climate Change On End-Use Energy Demand, Roshanak Nateghi, Sayanti Mukherjee

Energy Publications

Projecting the long-term trends in energy demand is an increasingly complex endeavor due to the uncertain emerging changes in factors such as climate and policy. The existing energy-economy paradigms used to characterize the long-term trends in the energy sector do not adequately account for climate variability and change. In this paper, we propose a multi-paradigm framework for estimating the climate sensitivity of end-use energy demand that can easily be integrated with the existing energy-economy models. To illustrate the applicability of our proposed framework, we used the energy demand and climate data in the state of Indiana to train a Bayesian …

Statistical Results On The Performance Of An Adaptive-Threshold Radar Detector In The Presence Of Wireless Communications Interference Revision 1, David P. Zilz, Mark R. Bell

Department of Electrical and Computer Engineering Technical Reports

In an article recently accepted for publication in the IEEE Transactions on Aerospace and Electronic Sys-tems [1], we investigate the problem of specifying interference protection criteria for a radar sharing spectrum with wireless communications. In that paper, we first propose a statistical model for wireless communications interference based on existing interference and clutter models and supported by original simulations. Then we model the statistical effects of such interference on the detection performance of a cell-averaging adaptive-threshold radar detector. While the IEEE paper summarizes the statistical results and plots some representative figures, many additional calculations were computed than could be presented …

The Role Of Argumentation In Hypothetico-Deductive Reasoning During Problem-Based Learning In Medical Education: A Conceptual Framework, Hyunjung Ju, Ikseon Choi

Interdisciplinary Journal of Problem-Based Learning

One of the important goals of problem-based learning (PBL) in medical education is to enhance medical students’ clinical reasoning—hypothetico-deductive reasoning (HDR) in particular—through small group discussions. However, few studies have focused on explicit strategies for promoting students’ HDR during group discussions in PBL. This paper proposes a novel conceptual framework that integrates Toulmin’s argumentation model (1958) into Barrows’s HDR process (1994). This framework explains the structure of argumentation (a claim, data, and a warrant) contextualized in each phase of HDR during PBL. This paper suggests four instructional strategies—understanding argument structures, questioning, elaborating on structural knowledge, and assessing argumentation—for promoting medical …

Problem-Based Learning Pedagogies In Teacher Education: The Case Of Botswana, Thenjiwe Major, Thalia M. Mulvihill Dr.

Interdisciplinary Journal of Problem-Based Learning

The development of primary school teachers is an important aspect of a country’s economic, social, and political well-being. The use of particular pedagogies in teacher education may greatly influence how teachers perform in their classrooms after completing their training programs. This micro-ethnography investigated the extent to which teacher educators in Botswana’s College of Education used problem-based learning (PBL) approaches in the development of preservice primary teachers. While the findings of this micro-ethnography showed that particular teacher educators rarely used problem-based learning approaches, the accompanying insights helped to bring a deeper understanding of what is needed for Botswana’s teacher education program …

Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer

Journal of Applied Farm Economics

This study evaluated the feasibility of reintroducing mechanical weed control as an alternative for herbicide-resistance weed infestations. The production practice tested included row cultivation with a separate banded spray application using high-accuracy automated guidance systems. A range of ground speeds were tested for the row cultivation operation, each with a different per acre cost and timeliness penalty. A typical eastern Corn Belt farm with a rotation of corn and soybean served as the base for the linear programming model. It was found that if the farmer was willing to reintroduce tillage, row cultivation conducted at higher operating speeds in conjunction …

Liaison Librarians In The Know: Methods For Discovering Faculty Research And Teaching Needs, Nora B. Wood, Melanie Griffin

Charleston Library Conference

Libraries constantly seek information from their faculty partners on what, precisely, is needed from the library to support their teaching and research needs. This paper uses a case study from the University of South Florida (USF) as a framework to explore methods for determining the curriculum and research needs of faculty across disciplinary boundaries and ways for promoting library resources and services to departments across campus. Using syllabus analysis, website analysis, focus groups, and interviews, this project sought to evaluate faculty needs without relying on surveys. The data gathered from this case study will allow the liaisons at the University …

Wrangle Your Data Like A Pro With The Data Processing Power Of Python, Geoffrey P. Timms, Jeremy M. Brown

Charleston Library Conference

Management, delivery, and marketing of library resources and collections necessitate interaction with a plethora of data from many sources and in many forms. Accessing and transforming data into meaningful information or different formats used in library automation can be time consuming, but a working knowledge of a programming language can improve efficiency in many facets of librarianship. From processing lists to creating extensible markup language (XML), from editing machine-readable cataloging (MARC) records before upload to automating statistical reports, the Python programming language and third-party application programming interfaces (APIs) can be used to accomplish both behind-the-scenes tasks and end-user facing projects. …

Supporting Research Information Management In The Research University: Partnerships, Challenges, And Possibilities, Rebecca Bryant, Beth Sandore Namachchivaya, Julie Speer

Charleston Library Conference

Research universities are increasingly engaging in complex efforts to collect and synthesize information about an institution’s research footprint. The collection, updating, and sharing of the campus’s bibliographic research outputs is an increasingly important part of this effort, as institutions seek to develop external profiling systems and enable collaborator discovery and to also increasingly internally understand the research strengths and synergies of an institution for planning and assessment. Institutions are adopting a variety of tools to support research information management (RIM), faculty activity reporting (FAR), and researcher collaboration and discovery on campus. In this presentation, we will talk about the complex …

Is A Gold Open Access World Viable For Research Universities?, Greg Tananbaum, Carol Tenopir, Ivy Anderson

Charleston Library Conference

Open access is at the heart of a seismic shift in scholarly publishing. In particular, gold open access (OA) has expanded at an accelerated pace, increasing in market share every year. In the gold OA model, financial viability shifts from the demand to the supply side, with article processing charges (APCs) a common scenario. Ideally, this model would be sustainable for academic research institutions, in that it would cost them cumulatively no more to pay APCs than they pay now in the traditional subscription model. APC-driven gold OA has financial and other implications for libraries, institutions, and authors. In the …

Bridging The Divide: Collaborating Across Departments To Improve Communication And Collections, Nancy Fawley, Laura Gewissler

Charleston Library Conference

Flat budgets, rising subscription rates, and the need to communicate the (bad) news to librarians and faculty are part of the academic library landscape. Additionally, the University of Vermont recently implemented incentivebased budgeting, requiring financial transparency and demonstration of value to community stakeholders. Collaborative efforts between liaison librarians and collection management departments are increasingly necessary as libraries work to support research, teaching, and learning with fewer resources. This article will focus on the venues and the mechanisms that facilitate a culture of librarians sharing information across departments about financial realities within the libraries and the university to promote cooperative decision-making …

Scholarly Needs For Text Analysis Resources: A User Assessment Study For The Hathitrust Research Center, Harriett E. Green, Eleanor F. Dickson, Leanne R. Nay, Ewa Zegler-Poleska

Charleston Library Conference

The HathiTrust Research Center (HTRC) is undertaking a study to better understand the needs of current and potential users of the center’s tools and services for computational text analysis. In this paper, we report on the results of the first phase of the study, which consisted of interviews with scholars, administrators, and librarians whose work involves text data mining. Our study reveals that text analysis workflows are specific to the individual research project and are often nonlinear. In spite of, and in some cases because of, the wealth of textual data available, scholars find it most difficult to locate, access, …
