Pseudocapacitors For Energy Storage, Anuradha Venkataraman

Dissertations and Theses

Fluctuation in the demand for electrical power and the intermittent nature of the supply of energy from renewable sources like solar and wind have made the need for energy storage a dire necessity. Current storage technologies like batteries and supercapacitors fall short either in terms of power output or in their ability to store sufficient energy. Pseudocapacitors combine features of both and offer an alternative to stabilize the power supply. They possess high rates of charge and discharge and are capable of storing much more energy in comparison to a supercapacitor. In the quest for solutions that are economical and …

Development And Study Of Waterproof Breathable Fabric Using Silicone Oil And Polyurethane Binder, Aditi S. Bakshi

Master's Theses and Doctoral Dissertations

The focus of this study is on determining the optimum combination of hydrophilic and hydrophobic components in coating material to obtain high breathability and waterproof properties. Polyurethane binder and silicone oil were used in eight different combinations to coat the fabric along with one sample with 100% polyurethane binder for control. A knife-over-roll coating machine was used to coat the fabric. The coated samples were tested by using the Sweating Guarded Hot Plate method for breathability and the spray test and contact angle method for waterproof properties. Results obtained from the tests showed that fabric coated with an 80%-20% and …

The Spectrum Of Control: A Social Theory Of The Smart City, Jathan Sadowski, Frank A. Pasquale

Faculty Scholarship

There is a certain allure to the idea that cities allow a person to both feel at home and like a stranger in the same place. That one can know the streets and shops, avenues and alleys, while also going days without being recognized. But as elites fill cities with “smart” technologies—turning them into platforms for the “Internet of Things” (IoT): sensors and computation embedded within physical objects that then connect, communicate, and/or transmit information with or between each other through the Internet—there is little escape from a seamless web of surveillance and power. This paper will outline a social …

Scalable Euclidean Embedding For Big Data, Zohreh S. Alavi, Sagar Sharma, Lu Zhou, Keke Chen

Kno.e.sis Publications

Euclidean embedding algorithms transform data defined in an arbitrary metric space to the Euclidean space, which is critical to many visualization techniques. At big-data scale, these algorithms need to be scalable to massive dataparallel infrastructures. Designing such scalable algorithms and understanding the factors affecting the algorithms are important research problems for visually analyzing big data. We propose a framework that extends the existing Euclidean embedding algorithms to scalable ones. Specifically, it decomposes an existing algorithm into naturally parallel components and non-parallelizable components. Then, data parallel implementations such as MapReduce and data reduction techniques are applied to the two categories of …

Becoming "Smart" About Relationship Building: Foster Care Youth And The Use Of Technology, Ramona Denby Brinson, Efren Gomez, Keith A. Alford

Lincy Institute Reports and Briefs

Key Findings:

Youth participants reported satisfaction with services and positive feelings about the smartphone.

The youth participants felt that the smartphone gave them a “voice” and control over the people with whom they wanted to talk.

Certain phone restrictions developed by project leadership were unenforceable.

Youth had certain expectations about the phone and its use but when the phone did not work or was “locked” (e.g., for data overuse) it created friction between the youth and their service provider.

Service-providers report that the phones help to create a sense of normalcy for the youth. Youth “were able to be normal …

Evaluating A Potential Commercial Tool For Healthcare Application For People With Dementia, Tanvi Banerjee, Pramod Anantharam, William L. Romine, Larry Wayne Lawhorne

Kno.e.sis Publications

The widespread use of smartphones and sensors has made physiology, environment, and public health notifications amenable to continuous monitoring. Personalized digital health and patient empowerment can become a reality only if the complex multisensory and multimodal data is processed within the patient context, converting relevant medical knowledge into actionable information for better and timely decisions. We apply these principles in the healthcare domain of dementia. Specifically, in this study we validate one of our sensor platforms to ascertain whether it will be suitable for detecting physiological changes that may help us detect changes in people with dementia. This study shows …

Kno.e.sis Publications

With the advent of the web search and microblogging, the percentage of Online Health Information Seekers (OHIS) using these online services to share and seek health real-time information has in- creased exponentially. OHIS use web search engines or microblogging search services to seek out latest, relevant as well as reliable health in- formation. When OHIS turn to microblogging search services to search real-time content, trends and breaking news, etc. the search results are not promising. Two major challenges exist in the current microblogging search engines are keyword based techniques and results do not contain real-time information. To address these challenges, …

Teacher Perceptions Of Factors Influencing Their Self-Efficacy With Using One-To-One Technology During Literacy Instruction, Michael Todd Methvin

Graduate Theses and Dissertations

Teacher perceptions of factors that influence their own self-efficacy with using one-to-one technology during literacy instruction were examined through a multi-site, multi-subject case study. An initial survey was administered to determine the self-efficacy level of a group of participants from a school district that was implementing a one-to-one technology initiative. From this initial data set, four participants with varying levels of self-efficacy were invited to participate in the second, qualitative, phase of the data collection process to better understand factors they perceived to influence these levels. Results revealed that teachers perceived their self-efficacy of one-to-one technology use during literacy instruction …

Computers And Procrastination: Why So Little Research?, Nick Breems

Faculty Work Comprehensive List

As computer and internet technology becomes an ever-greater part of the fabric of our everyday lives, we find that not all of the effects are as beneficial as we might like. One frequently noticed example of this that working on a computer seems to make us more prone to procrastination. While this there is significant anecdotal evidence for this phenomenon, and it is nearly taken for granted in the popular press and productivity blogs, there has been very little research that directly addresses the intersection of computer use and procrastination. For a tool widely perceived to enhance our productivity, this …

The Beginning Of Digital Wisdom, Michael J. Paulus Jr., Ryan Ingersoll

SPU Works

Marc Prensky, who popularized the term “digital natives” more than ten years ago, now emphasizes the need for “digital wisdom”: using digital technologies wisely to become wiser. Recent research reveals that so-called digital natives are often “digital naïves”—familiarity with digital technologies does not translate into facility with them. Incoming college students report declining confidence in their computer skills and report very modest improvements by the time they graduate. Employers report deficiencies in the technological skills of college graduates and, perhaps most troubling, studies of youth and young adults show that ethical and moral reasoning does not extend much beyond self-protection. …

Understanding The Relationships Of User-Selected Music In Video Games, Memphis Wong

Liberal Arts and Engineering Studies

Music has been an integral part of video games in its contribution to users' gameplay experiences. Varying from simple sound effects to elaborate scores, music helps shape the reactive environment of each video game. In particular, video games that generate unique levels and scenarios based on music has become more popular as its own genre. Games such as Audiosurf take this further, with having the game revolve entirely around levels generated to custom tracks. The aim of this study is to analyze the impact of such games, when it allows a user to select his or her own music.

Entity Recommendations Using Hierarchical Knowledge Bases, Siva Kumar Cheekula, Pavan Kapanipathi, Derek Doran, Prateek Jain, Amit P. Sheth

Kno.e.sis Publications

Recent developments in recommendation algorithms have focused on integrating Linked Open Data to augment traditional algorithms with background knowledge. These developments recognize that the integration of Linked Open Data may or better performance, particularly in cold start cases. In this paper, we explore if and how a specific type of Linked Open Data, namely hierarchical knowledge, may be utilized for recommendation systems. We propose a content-based recommendation approaches that adapts a spreading activation algorithm over the DBpedia category structure to identify entities of interest to the user. Evaluation of the algorithm over the Movielens dataset demonstrates that our method yields …

Recently, Twitter has emerged as one of the primary mediums for sharing and seeking of the latest information related to a variety of topics, including health information. Although Twitter is an excellent information source, the identification of useful information from the deluge of tweets is one of the major challenges. Twitter search is limited to keyword-based techniques to retrieve information for a given query and sometimes the results do not …

Spatial, Temporal And Demographical Analysis Of Gulf Of Mexico Research Priorities, The Effect Of The Deepwater Horizon Oil Spill, Stephen Hiller Sempier

Dissertations

A set of twenty equally-weighted national ocean research priorities were define in 2007, but it was not clear if these priorities applied for the Gulf of Mexico. A series of three longitudinal surveys of people who conduct research, sponsor research or use research for professional or recreational purposes was released that focused on the twenty research priorities and asked people how they rated each. A convenience sampling method was employed, which suggests that the results are constrained to the survey respondents and should not be extrapolated to a larger population. More than 1,500 people completed the 2013 GMRP survey and …

Analyzing The Social Media Footprint Of Street Gangs, Sanjaya Wijeratne, Derek Doran, Amit P. Sheth, Jack Dustin

Kno.e.sis Publications

Gangs utilize social media as a way to maintain threatening virtual presences, to communicate about their activities, and to intimidate others. Such usage has gained the attention of many justice service agencies that wish to create better crime prevention and judicial services. However, these agencies use analysis methods that are labor intensive and only lead to basic, qualitative data interpretations. This paper presents the architecture of a modern platform to discover the structure, function, and operation of gangs through the lens of social media. Preliminary analysis of social media posts shared in the greater Chicago, IL region demonstrate the platform’s …

The Snowden Effect: The Conflict In A Free Society, Who Values Privacy Versus Who Values Security?, Matthew C. Blake

Political Science Theses and Capstones

The Obama Administration has come under scrutiny by both the public and Congress, since former National Security Agency (NSA) contractor Edward Snowden made known the scope of government surveillance programs being utilized by the U.S. government to gather intelligence on domestic citizens. Snowden’s disclosures about the government’s surveillance practices to the mainstream media began in June 2013. I focus on how public opinion towards the government’s surveillance practices and an individual’s reasonable right to privacy has shifted after revelations made by Edward Snowden on the practices of the NSA. Individuals may show support for more government surveillance in the name …

Sociological Impacts Of Wind Farms In Maine, Jeanne Barthold

CLAS: Colby Liberal Arts Symposium

Renewable power has emerged in the last decade as a viable alternative for our societies' fossil fuel dependence. The Maine Wind Energy Act of 2009 made lofty goals for the amount of wind power that Maine wanted to produce by the year 2020. The many sides of the debate on Maine windmills that have arisen in the past six years create a picture that is extremely complicated. There is clearly not one solution to the problems that came with the rapid construction of windmills since the passing of the Maine Wind Energy Act. The rural communities most directly affected by …

Learning From Cinara: Exploring The Depths Of Participatory Water Engagement In Cali, Colombia, Zachary T. Strickland

Honors College Theses

Located within the Universidad del Valle in Cali, Colombia, CINARA is an academic institution, comprised of both engineers and social scientists, that has almost three decades of experience regarding participatory approaches to water supply and environmental sanitation. In this paper, I argue that CINARA’s work is important due to its emphasis on meaningful community participation that significantly involves communities in decisions on technical matters that are usually allocated exclusively to “experts.” Furthermore, the valuation of social considerations and non-technical knowledge found amongst CINARA’s engineers stands in distinct contrast to traditional development practices and engineering mindsets. This paper will go on …

Talking To Ourselves: Internal Communication Strategies For Reference Services, John Gottfried, Laura Delancey, Amanda Hardin

DLTS Faculty Publications

At many academic libraries, spiral notebooks and three ring binders have given way to blogs and wikis as a means of facilitating communication at the reference desk. Western Kentucky University Libraries opted instead to create a custom internal website to log reference transactions, highlight current issues, and manage scheduling changes. This solution incorporated numerous platforms and technologies, including LibGuides, Facebook, and Google Calendar. It avoided some of the pitfalls described in the literature, such as relying too heavily on user-generated content, and has been successful largely because it is embedded in the reference workspace and contains features that librarians will …

Determining The Degree Of Collaboration Readiness For Regional Transportation Systems: The Formulation Of A Model, Carol Farver

Master's Theses and Doctoral Dissertations

The purpose of this study was to identify factors, both governmental and universal, that indicate the degree of readiness and/or potential for success of a government collaborative project in the field of regional rapid mass transportation. The study is important because collaboration has been recognized as a tool that can help address such challenges as demonstrating the responsible use of limited resources, anticipating converging technologies, and reacting to rapidly changing technologies. There was very limited availability of tools to assist in ensuring successful collaborations. Although tools have been developed that gauge the degree of collaborative readiness of a project, such …

Context-Driven Automatic Subgraph Creation For Literature-Based Discovery, Delroy H. Cameron, Ramakanth Kavuluru, Thomas Rindflesch, Amit P. Sheth, Krishnaprasad Thirunarayan, Olivier Bodenreider

Kno.e.sis Publications

Background: Literature-based discovery (LBD) is characterized by uncovering hidden associations in non-interacting scientific literature. Prior approaches to LBD include use of: 1) domain expertise and structured background knowledge to manually filter and explore the literature, 2) distributional statistics and graph-theoretic measures to rank interesting connections and 3) heuristics to help eliminate spurious connections. However, manual approaches to LBD are not scalable and purely distributional approaches may not be sufficient to obtain insights into the meaning of poorly understood associations. While several graph-based approaches have the potential to elucidate associations, their effectiveness has not been fully demonstrated. A considerable degree of …

New Directions In Hydro-Climatic Histories: Observational Data Recovery, Proxy Records And The Atmospheric Circulation Reconstructions Over The Earth (Acre) Initiative In Southeast Asia, Fiona Williamson, Rob Allan, Adam Switzer, Johnny C. L. Chan, Robert James Wasson, Rosanne D'Arrigo, Richard Gartner

Research Collection School of Social Sciences

The value of historic observational weather data for reconstructing long-term climate patterns and the detailed analysis of extreme weather events has long been recognized (Le Roy Ladurie, 1972; Lamb, 1977). In some regions however, observational data has not been kept regularly over time, or its preservation and archiving has not been considered a priority by governmental agencies. This has been a particular problem in Southeast Asia where there has been no systematic country-by-country method of keeping or preserving such data, the keeping of data only reaches back a few decades, or where instability has threatened the survival of historic records. …
