Adaptation Of The Nevada Climate Change Data Portal Web Interface To Small-Screen Mobile Devices, Tsvetan Komarov

Festival of Communities: UG Symposium (Posters)

Robust and convenient access to the Nevada Climate Change Data Portal is vital for the project’s success, because of the researchers’ need to gather and analyze large volumes of data with minimal effort. However, the current version of the data portal web interface is not optimized for small-screen mobile devices such as mobile phones, PDAs, iPads, NetBooks, and others. The proposed research will address this issue by exploring the current methods for creating a client-aware web interface adaptable to the variety of small-screen devices, designing and implementing the most appropriate solution, and finally, user testing of the implemented solution.

The Stress Coping Skills Of Undergraduate Collegiate Aviators, Jennifer Kirschner

Purdue Polytechnic Masters Theses

An important human factors research interest area is error reduction. Although pilots placed in highly stressful situations have an increased chance of making errors, they use coping skills to lower their stress level and reduce the likelihood of errors. Typically, coping skills are conceptually separated into three different types: active coping skills which attack and change the situation to make it inherently less stressful, emotionfocused coping skills which use discussion or thinking about the situation in a different way to diminish the negative emotional reaction associated with the stressful situation, and avoidant coping skills which allow one to mentally and/or …

After The Fire Is Out, Elise Lequire

Joint Fire Science Program Digests

Even before firefighters have left a burn site, a second wave of specialists is deployed. Their task: to assess the burn site; determine the level of risk to life, property, and ecological resources; and determine quickly the most effective postfire treatments for emergency stabilization and initial rehabilitation of the site. For the past 13 years, the Joint Fire Science Program (JFSP) has funded research on this critical phase of work, which often goes unnoticed after the fire is out. With support from the JFSP, scientists have made great strides in improving the tools available to assess postfire risks and evaluate …

Why Do Some Nations Have More Renewable Energy Policies?, Melissa Dahl

Political Science Theses and Capstones

Some nations have considerably more renewable energy policies than others and this research is attempting to discover why. Renewable energy use is quickly growing in our world and has become a major topic in today’s politics. Existing literature suggests various theories as to why some nations have more renewable energy policies than others. I test these theories with data from two major data sources; REN21, the Renewable Energy Policy Network for the 21st Century, and the International Energy Agency. I anticipate that nations with a larger number of effective political parties, higher GDPs, and larger population would have more renewable …

Identifying And Implementing The Underlying Operators For Nuclear Magnetic Resonance Based Metabolomics Data Analysis, Ashwin Manjunatha, Ajith H. Ranabahu, Paul E. Anderson, Amit P. Sheth

Kno.e.sis Publications

The science of metabolomics is a relatively young field that requires intensive signal processing and multivariate data analysis for interpretation of experimental results. The lack of integration and standardization for metabolomics compounded by the complexity of the experimental data has lead to a fragmented research community. While efforts have been undertaken to approach these problems, the efforts to develop a set of standards for reporting processing and analysis procedures has stalled.

In this paper, we propose a set of fundamental operators for nuclear magnetic resonance(NMR) based metabolomics. These operators are implementation independent, and can be used to easily and precisely …

Adolescent Use Of Social Networking Sites And Internet Safety, Mary Kate Whitcomb

Psychology and Child Development

The use of computers and the Internet continue to increase, especially by children and adolescents. Approximately 40% of adolescents access social networking sites in a typical day and spend on average 54 minutes on the sites (Rideout, Foehr, & Roberts, 2010). Social networking sites, such as Facebook, allow users to provide personal information, continually update information, post images, and communicate with friends. Due to an increase in availability, media has become greatly related to the socialization of adolescents. Identity formation is a major component of adolescence and social networking sites are a realm in which adolescents can explore and express …

Confronting Socially Generated Uncertainty In Adaptive Management, Andrew J. Tyre, Sarah Michaels

School of Natural Resources: Faculty Publications

As more and more organizations with responsibility for natural resource management adopt adaptive management as the rubric in which they wish to operate, it becomes increasingly important to consider the sources of uncertainty inherent in their endeavors. Without recognizing that uncertainty originates both in the natural world and in human undertakings, efforts to manage adaptively at the least will prove frustrating and at the worst will prove damaging to the very natural resources that are the management targets. There will be more surprises and those surprises potentially may prove at the very least unwanted and at the worst devastating. We …

A Genetic Optimization Approach For Isolating Translational Efficiency Bias, Douglas W. Raiford, Dan E. Krane, Travis E. Doom, Michael L. Raymer

Kno.e.sis Publications

The study of codon usage bias is an important research area that contributes to our understanding of molecular evolution, phylogenetic relationships, respiratory lifestyle, and other characteristics. Translational efficiency bias is perhaps the most well studied codon usage bias, as it is frequently utilized to predict relative protein expression levels. We present a novel approach to isolating translational efficiency bias in microbial genomes. There are several existent methods for isolating translational efficiency bias. Previous approaches are susceptible to the confounding influences of other potentially dominant biases. Additionally, existing approaches to identifying translational efficiency bias generally require both genomic sequence information and …

A Systematic Property Mapping Using Category Hierarchy And Data, Kalpa Gunaratna, Sarasi Lalithsena, Prateek Jain, Cory Andrew Henson, Amit P. Sheth

Kno.e.sis Publications

Relationships play a key role in Semantic Web to connect the dots between entities (concepts or instances in a way that enables to absorb the real sense of the entities. Even though relationships are important, it is difficult to categorize or identify them because they consist of complex knowledge in the schema. Therefore systematically identifying relationships yield many advantages and open doors for new research avenues. In this work, we try to identify a specific type of relationship (part of) in a multi-domain dataset and devised an algorithm using Wikipedia to identify patterns of part of relationships in the dataset. …

Kno.e.sis Publications

The problem of efficient and high-quality clustering of extreme scale datasets with complex clustering structures continues to be one of the most challenging data analysis problems. An innovate use of data cloud would provide unique opportunity to address this challenge. In this paper, we propose the CloudVista framework to address (1) the problems caused by using sampling in the existing approaches and (2) the problems with the latency caused by cloud-side processing on interactive cluster visualization. The CloudVista framework aims to explore the entire large data stored in the cloud with the help of the data structure visual frame and …

Analysis On Partial Relationship In Lod, Kalpa Gunaratna, Sarasi Lalithsena, Cory Andrew Henson, Prateek Jain

Kno.e.sis Publications

Relationships play a key role in Semantic Web to connect the dots between entities (concepts or instances) in a way that enables to absorb the real sense of the entities. Some interesting relationships would give proof for the existence of subject and object in triples which in tern can be defined as evidential relationships. Identifying evidential relationships will yield solutions to some existing inference problems and open doors for new applications and research. Part_of relationships are identified as a special kind of an evidential relationship out of membership, causality and etc. Linked Open data as a global data space would …

Contextual Ontology Alignment Of Lod With An Upper Ontology: A Case Study With Proton, Prateek Jain, Peter Z. Yeh, Kunal Verma, Reymonrod G. Vasquez, Mariana Darnorva, Pascal Hitzler, Amit P. Sheth

Kno.e.sis Publications

The Linked Open Data (LOD) is a major milestone towards realizing the Semantic Web vision, and can enable applications such as robust Question Answering (QA) systems that can answer queries requiring multiple, disparate information sources. However, realizing these applications requires relationships at both the schema and instance level, but currently the LOD only provides relationships for the latter. To address this limitation, we present a solution for automatically finding schema-level links between two LOD ontologies – in the sense of ontology alignment. Our solution, called BLOOMS+, extends our previous solution (i.e. BLOOMS) in two significant ways. BLOOMS+ 1) uses a …

Reconciling Owl And Rules, David Carral Martinez, Adila A. Krisnadhi, Frederick Maier, Kunal Sengupta, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We report on a recent advance in integrating Rules and OWL. We discuss a recent proposal, known as nominal schemas, which realizes a seamless integration of Datalog rules into the description logic SROIQ which underlies OWL 2 DL. We present extensions of the standardized OWL syntaxes to incorporate nominal schemas, reasoning algorithms, and a first naive implementation. And we argue why this approach goes a long way towards overcoming the present paradigm split.

Privacy-Aware An Scalable Content Dissemination In Distributed Social Networks, Pavan Kapanipathi, Julia Anaya, Amit P. Sheth, Brett Slatkin, Alexandre Passant

Kno.e.sis Publications

Centralized social networking websites raise scalability issues - due to the growing number of participants - and, as well as, policy concerns - such as control, privacy and ownership over the user's published data. Distributed Social Networks aim to solve this issue by enabling architecture where people own their data and share it their own way. However, the privacy and scalability challenge is still to be tackled. This paper presents a privacy-aware extension to Google's PubSubHubbub protocol, using Semantic Web technologies, solving both the scalability and the privacy issues in Distributed Social Networks. We enhanced the traditional feature of PubSubHubbub …

A Unified Framework Fro Managing Provenance Information In Translational Research, Satya S. Sahoo, Vinh Nguyen, Olivier Bodenreider, Priti Parikh, Todd Minning, Amit P. Sheth

Kno.e.sis Publications

Background

A critical aspect of the NIH Translational Research roadmap, which seeks to accelerate the delivery of "bench-side" discoveries to patient's "bedside," is the management of the provenance metadata that keeps track of the origin and history of data resources as they traverse the path from the bench to the bedside and back. A comprehensive provenance framework is essential for researchers to verify the quality of data, reproduce scientific results published in peer-reviewed literature, validate scientific process, and associate trust value with data and results. Traditional approaches to provenance management have focused on only partial sections of the translational research …

Methodology For Evaluating Statistical Equivalence In Face Recognition Using Live Subjects With Dissimilar Skin Tones, Bryan Baker

Masters Theses

The question sought in this study is whether there is a significant statistical difference between a facial recognition system's ability to recognize dark or light skin tone subjects. In addition to the direct comparison of results from two different populations, this study also examines four factors commonly effecting facial recognition systems. The four factors tested were angle of the camera viewing the subject; both horizontally to the left and right, as well as vertically, both above and below the subject's line of sight.

Additionally, the distance the subjects are from the camera, and then intensity of the illumination on the …

Mentor Perceptions Of Closure In Formal Youth Mentoring Relationships, Anna Maria Peterson

Masters Theses

In formal community-based youth mentoring relationships, mentors and mentees travel through phases of a relationship from inception through closure. To form an understanding of mentor perceptions of the closure phase of those relationships, a Glaserian grounded theory survey was conducted. Mentors located in central Illinois participated in the survey providing their perceptions, insights and experiences regarding the closure phase of the youth mentoring relationships in which they were involved.

Key Factors Affecting Color Reproduction On T-Shirt Fabrics Using Heat Transfer Printing, Molly Frank

Masters Theses

Dye sublimation heat transfer printing is commonly used to transfer an image to fabric for small production runs. This process is very inexpensive and is very quick. Unlike digitally printing on fabric, there is no need to treat the fabric once the image has been transferred onto it. Heat transfer printing is also commonly used due to the fact that three different factors can be controlled while printing. These three factors are the temperature, the dwell time, and the pressure. Color reproduction is easy to do once the correct combination of these three factors is found. The temperature, time, and …

Obtaining Speech Assets For Judgement Analysis On Low-Pass Filtered Emotional Speech, John Snel, Charlie Cullen

Conference papers

Investigating the emotional content in speech from acoustic characteristics requires separating the semantic con- tent from the acoustic channel. For natural emotional speech, a widely used method to separate the two channels is the use of cue masking. Our objective is to investigate the use of cue masking in non-acted emotional speech by analyzing the extent to which filtering impacts the perception of emotional content of the modified speech material. However, obtaining a corpus of emotional speech can be quite difficult whereby verifying the emotional content is an issue thoroughly discussed. Currently, speech research is showing a tendency toward constructing …

The Obvious Invisibility Of The Relationship Between Technology And Social Values, Jamie P. Ross

Women, Gender, and Sexuality Studies Faculty Publications and Presentations

We all too often assume that technology is the product of objective scientific research and that technology’s moral value lies in only the moral character of its user. To remove technology from a moral realm, we assume value and context neutrality. Yet the power of technology is a reflection of the values that exist in its developmental context. Technology’s moral realm is visible in the reciprocal relationship between culture and technology in the epidemiology of AIDS, clinical research and practice regarding heart disease, and DNA research. Cultural values decide what counts as a scientific question. When we look at the …
