Library Guides: An Aggregation Of User Research From 1998 To 2017, David Vess

Libraries

A truly comprehensive search tool for resources provided by libraries will continue to be a distant dream until daunting technical challenges are addressed. A Google-like search experience is desirable in some contexts, but a case can be made that hiding subject-specific article databases behind a comprehensive search tool is a disservice to researchers.

Librarians have a long history of addressing the complex landscape of the various resources they offer by crafting guides to library collections. These guides provide direct links to resources while educating inexperienced researchers about discipline-specific databases. Unfortunately, this solution creates more complexities in the research resource landscape. …

Unsupervised Machine Learning In Agent-Based Modeling, Luke D. Robinson

Celebration of Learning

Agent-based models (ABMs) are used by researchers in a variety of fields to model natural phenomena. In an ABM, a wide range of behaviors and outcomes can be observed based on the parameters of the model. In many cases, these behaviors can be categorized into discrete outcomes identifiable by human observers. Our goal was to use clustering algorithms to identify those outcomes from model output data. For this project, we used data from the NetLogo Wolf Sheep Predation model to explore and evaluate three clustering algorithms from Python's scikit-learn package. If this task can be completed reliably by a computer, …

The Chess Puzzle Lock Screen, Ryan J. Hayes

The Chess Puzzle Lock Screen

Many times each day, owners of cellphones use their phone’s lock screen in order to access their device. The goal of this project has been to take advantage of the action of unlocking one’s device by incorporating an element of self-help into the process. Every time a user who is interested in learning a new field attempts to access their device, that user is faced with a problem pertaining to a subject they are interested in learning more about. After many repetitions of this scenario, the user will have increased their understanding of this field. …

Virtual Reality: Google Cardboard And Unity, Emma Elliott

Student Scholar Showcase

Virtual Reality is currently the hottest way for people to play video games because it provides an immersive and interactive world to explore. It uses computer software to create sounds, realistic images, and other effects to simulate a virtual setting. The current craze started on the Oculus Rift headset and has incited other companies to make their own, but most are expensive or require another system to play. Instead of buying an expensive headset, anyone with a smartphone can play in Virtual Reality with Google’s cheap alternative, the Google Cardboard. The goal of this project is to complete a prototype …

Optimizing Campus Mobility With A Focus On Sustainability: A Graph Theory Approach To Intra-Campus Transportation Networks, Quinn M. Nelson

UNO Student Research and Creative Activity Fair

The idea of public transportation is supported by most in theory but often heavily criticized by users when put into application. There are common tensions that are related to public transportation, as described by frequent users: unreliable, too crowded, and slow. The University of Nebraska-Omaha (UNO) is a growing metropolitan institution that uses a shuttle system to transport students among their three campuses daily. As of 2015, the current total student enrollment is approximately 16,000; UNO plans to enroll 20,000 students by 2020. The expected student growth is also reflected by the current construction of new buildings and expansion of …

A Modular Robotic System For Assessment And Exercise Of Human Movement, Mohan Sai Ambati

UNO Student Research and Creative Activity Fair

This project targets the problem of developing a wearable modular robotic system, for assessing human movement and providing different types of exercises for the user. The system attempts to provide not only a variety of exercises (concentric, eccentric, assisted and resisted), but also to assess the change in variability of the movement as the subject shows functional improvement. The system will not only be useful for patients with sensorimotor problem such as stroke, Parkinson’s, cerebral palsy, but also for special populations such as astronauts who spend long periods of time in space and experience muscle atrophy. In this work, a …
