Graph Games: A Human Computing Game Framework, Ryan Alfuth, Matt Jara, Jeff Largent, Dan Simpson

10th Annual Celebration of Undergraduate Research and Creative Performance (2011)

Graph Games is a suite of online casual games that make use of human computation to help solve several NP-complete graph problems. These problems are very difficult for computers to solve efficiently because they rapidly become computationally infeasible as their size increases. However, humans possess intelligent decision-making abilities that computers do not, so they can solve these problems more resourcefully than computers.

Graph Games seeks to harness these abilities to increase the body of knowledge about solving NP-complete problem by presenting problems in the form of puzzle-like games. Graph Games currently consists of three families of games, each being comprised …

A “Peak” At The Algorithm Behind “Peaklet Analysis” Software, Bruce Kessler

Mathematics Faculty Publications

In response to a problem posed by faculty at the Applied Physics Institute at Western Kentucky University, the speaker has developed an algorithm for providing an automated analysis of spectrum data for the purpose of determining the elemental composition of the item generating the data. A full, non-provisional patent application has been filed on the idea, and a full marketing campaign has started to license software implementing the algorithm.

Surface Geometry And Heat Flux Effect On Thin Wire Nucleate Pool Boiling Of Subcooled Water In Microgravity, Troy Munro, Andrew Fassman

Presentations

The motivation of this nucleate boiling research is to understand the effects of surface geometry and heat flux as applied to a thin wire heater. This will further the understanding of the fundamental behaviors of boiling onset, steady state heat transfer, and bubble dynamics with respect to nucleate boiling with the goal of creating efficient thermal management systems for future space applications. Using three different thin platinum wire geometries and five different power levels, subcooled water was boiled over a period of approximately 30 seconds for 15 parabolic arcs to simulate microgravity. To represent the trends in bubbles behavior across …

I was invited by the communities impacted and the different actors involved to participate in the team in charge of developing methodologies to valuate the social-environmental externalities faced by the communities, …

Environmental Sustainability: Challenges And Opportunities Of Greening Your Study Abroad Program, Sylvia M. Seger Mim, Academic Director

Fostering Multicultural Competence and Global Justice: an SIT Symposium

World Learning’s mission to “… create a more peaceful and just world” by necessity encompasses environmental dynamics, considering that the root causes of most social justice issues and violent conflicts can be traced to environmental degradation and disproportional access to shrinking natural resources. Thus our mission mandates that we employ an ethic of environmental stewardship in all our pursuits and put in place mechanisms to mitigate our environmental impacts.

“We shall never achieve harmony with land, any more than we shall achieve absolute justice or liberty for people. In these higher aspirations, the important thing is not to achieve but …

Citrate Synthase And The Visual Interactions Hypothesis, Kristina Camarena

Senior Honors Projects

It has been shown that the metabolic rates of deep-living species of particular pelagic groups are significantly lower than those that live closer to the surface in the water column. Various theories as to why have been presented, including the visual interactions hypothesis, which states that because there is a greatly minimized ability to visually interact in the light-limited deep, predators have a reduced need for high metabolic rates because they do not actively go after their prey. Citrate synthase is a mitochondrial enzyme found at the beginning of the citric acid cycle, which plays an integral role in cellular …

Facilitating Behavior Change Of Coastal Communities In Regards To Climatic Hazards, Marisa Nixon

Senior Honors Projects

For my Senior Honors Project I participated in the Climate Change Collaborative, which is a new interdisciplinary research project studying the ways in which coastal communities in Rhode Island can better adapt to the environmental, cultural and economic consequences of climate change. As a member of this collaborative, I worked in a vertically integrated team of faculty (psychology researchers, climate scientists and communications science practitioners and researchers) as well as undergraduate and graduate students, to begin an endeavor through which behavior change will be assessed in regards to climate change. For the purposes of this study, we specifically focus on …

The poster provides background about Utah State University’s situation and explains our approach to analyzing local needs and culture to inform development of a new organizational structure. We describe our vision of subject librarianship, the process by which we assessed librarians’ ideas and goals for performing as subject librarians, and the actions we are taking to …

An Algorithm For Wavelet–Based Elemental Spectrum Analysis, Bruce Kessler

Mathematics Faculty Publications

At the previous Approximation Theory XII meeting, I discussed some preliminary work with the Applied Physics Institute at Western Kentucky University in using multiwavelets to provide an objective analysis of gamma-ray spectrum generated from fast neutron bombardment of objects, for the purpose of identifying the elemental composition of the object. The method discussed at the time worked moderately well with the limited amount of data provided, but subsequent use with data sets of different compounds and with different detectors brought to light serious flaws with its implementation.

This talk will illustrate those issues and will address how they have been …

Using Twitter To Demonstrate Basic Concepts From Network Analysis, Matt Bogard

Economics Faculty Publications

Social network analysis focuses on finding patterns in interactions between people or entities. These patterns may be described in the form of a network. Network analysis in general has many applications including models of student integration and persistence, business to business supply chains, terrorist cells, or analysis of social media such as Facebook and Twitter. This presentation provides a reference for basic concepts from social network analysis with examples using tweets from Twitter.

Copper(Ii) Catalyzed Aminomethylation Of Alkanes With Amine N-Oxides Via C-H Bond Activation, Matthew Cipolla

Senior Honors Projects

The formation of a C-C bond via double C-H bond activation is very challenging. There are only a few examples of such a coupling having been accomplished. Only one of these examples consists of a coupling of two sp3 hybridized carbons. I set out to reproduce this coupling, using substrates that would have a functional application to the synthesis of appealing molecules such as bioactive molecules. Cyclohexane and trimethylamine N-oxide were successfully coupled via a double C-H bond activation, catalyzed by copper(II). Current research now involves the coupling of toluene with trimethylamine N-oxide. As this work progresses, more interesting and …

Watershed Sciences Faculty Publications

The Great Salt Lake of Utah is surrounded on its eastern and southern shores by 1.4 million people, with projections of 5 million by 2050. Agricultural, industrial and particularly secondary-treated domestic wastes from this population flow primarily into Farmington Bay, a 280 km2 shallow "estuary" with a mean depth near 0.5 m. Fish are rare but bird use is extensive and massive mortalities of waterfowl and shorebirds have occurred in the bay. Phosphorus loading rates of >2 g m-2yr-1 cause hypereutrophic conditions: Secchi depths are usually 0.6 mg/L, mean Chl. a is 179 ug/L and the combined trophic state index …

Differential Equations: A Universal Language, Bethany Caron

Senior Honors Projects

“Mathematics knows no races or geographic boundaries; for mathematics, the cultural world is one country.” – David Hilbert Differential equations are equations of one or more variables that involve both functions and their derivatives. These equations have many applications to the everyday “non-math” world, including modeling in engineering, physics, biology, chemistry, and economics. Differential equations are used when a situation arises where one needs to study a continuously changing quantity (expressed as a function) and its rate of change (expressed through its derivatives). The solutions to differential equations are functions that make the original equation hold true, and they can …
