A method and apparatus are disclosed for approximating in real time the fracture fatigue entropy (FFE) of a metallic object subjected to cyclic loading. Such objects experience fatigue, which can lead to failure after a number of loading cycles. The disclosed invention allows for real time monitoring of the entropy increase in a metallic object under cyclic loading, and allows for removing the object from service before fatigue fracture occurs. Through use of the present invention, users may keep metallic objects in service for longer periods, because such objects may be safely taken closer to the fatigue fracture point. The …

Using Accelerometer Data To Remotely Assess Predation Activity Of Arctic Wolves (Canis Lupus Arctos), Heather Shipp

Research on Capitol Hill

Arctic wolves (Canis lupus arctos) play an important role in ecosystems located in the far northern regions of the world; however, little information is available about them and their impacts on prey populations due to their remote location. Recently, there has been concern about declining caribou populations, which serve as an important food source for local Inuit peoples. As a result, there is an urgent need to better understand Arctic wolves and their influence on caribou abundance.

Dr. Dan MacNulty, a professor at Utah State University, is currently conducting research on Arctic wolves in the Fosheim Peninsula of Ellesmere Island, …

Stomatal Differences In Western Aspen And Linkage To Drought Tolerance, Brianne Palmer

Research on Capitol Hill

Aspen are the most widely distributed broadleaf tree in North America .However, aspen mortality is widespread across the Intermountain West. Researchers are attempting to determine the causes of the decline and propose future methods of management.

In order to survive, plants need to take in CO₂ through pores on their leaves called stomata. When the stomata are open, the plant takes in CO₂, however, water escapes. Therefore, stomata are important in regulating the drought response in plants. The size and the density of the stomata could influence the drought tolerance of an organism.

In Utah, there are …

Sexual Assault And The Doctrine Of Chances In The Courtroom, Ryan Wallentine

Research on Capitol Hill

Sexual assault can have devastating and long-lasting effects on victims, but many assailants get away with their crime without being prosecuted.

The doctrine of chances is a rule of evidence allowing evidences of past crimes, wrongs, or acts to show it is unlikely a defendant would be repeatedly and innocently involved in similar, suspicious circumstances.

Given that about 63.3% of assailants are repeat offenders, the doctrine of chances could effectively be used in sexual assault cases.

The main objective is to determine a precise probabilistic threshold for allowing the use of the doctrine of chances in sexual assault cases such …

Potential Regulation Of Deadly Water-Borne Shigella Bacteria Pathogenesis Through The Shigella Infection Protein Spa47, Jamie Kingsford

Research on Capitol Hill

• Shigella is a gram-negative, bacterial pathogen typically found in contaminated water sources.
• Each year, Shigella is responsible for over 90 million infections and 100,000 deaths stemming from symptoms of severe dysentery, fever, nausea and vomiting.
• A needle-like apparatus found on the surface of Shigella allows the bacterium to infect host cells.
• Each needle-apparatus has an associated ATPase, a protein that can hydrolyze ATP into ADP and P_i.
• The Shigella needle-apparatus ATPase Spa47 is predicted to provide the energy for infection.
• Spa47 has been shown to be essential for infection – without Spa47, no infection will occur.
• We were …

Conformal Symmetry: Finding New Physics In Scale Invariance, Benjamin C. Lovelady

Research on Capitol Hill

Modern physics is the study of symmetry. Everything from electromagnetism to the famed Higgs mechanism stems from fundamental symmetries. These have fancy mathematical names and even fancier math behind them, but the basic idea is the same. These are mathematical generalizations of normal transformations such as rotating. These symmetries describe fields (electric, magnetic, etc.).

Most models of unification, i.e. string theory, use "Poincare symmetry." This symmetry includes both translations and rotations. This means physics only cares about relative position, angle, velocity, etc. If I were to wake up in a windowless room that had been moved a mile north and …

Water Use Of Kentucky Bluegrass Varieties, Shawn Foster

Research on Capitol Hill

• With drought so prevalent in the West, water use on urban landscapes is being closely scrutinized with up to 60% of urban water use directed to landscape irrigation-primarily our lawns.
• Kentucky bluegrass (Poa pratensis L.) is widely used because of its soft texture, attractive color, and ability to recover from intensive use.
• More water-efficient varieties of Kentucky bluegrass may result in less irrigation yet maintain quality and function of the turf.

Demographic Consequences Of Climate Change In The Uinta Ground Squirrel, Kari Norman

Research on Capitol Hill

One important impact of climate change is shifts in the timing of life events such as reproduction and flowering. Hibernators like the Uinta Ground Squirrel are especially sensitive to potential shifts because they depend on food at essential times.

Chapter 2: Time Series, Sara A. Myers

Journal Articles

Time series is “simply a list of numbers assumed to measure some process sequentially in time” (Stergiou et al. 2004). Mathematicians have a more formal definition, that is, a set or a sequence of observations, with each one recorded at specific times, or at least sequentially (Brockwell and Davis 2002; Box et al. 2008). Time series are created from multiple sources for research purposes to understand various behaviors. For example, social scientists could collect graduation rates, physiologists record heart rates, economists study consumer spending, and climatologists examine weather patterns. Basically, any time observations are taken repeatedly over time, from any …

Chapter 8: Autocorrelation Function, Mutual Information, And Correlation Dimension, Nathaniel Hunt

Journal Articles

In this chapter, we will discuss in greater detail the autocorrelation function and the mutual information we mentioned in Chapter 3 on the reconstruction of the state space. We will also cover a new measure called the correlation dimension, which quantifies the dimensionality of an attractor.

An Introduction To Differential Geometry Through Computation, Mark E. Fels

Textbooks

The outline of the book is as follows. Chapter 1 reviews some basic facts about smooth functions from IRⁿ to IR^m, as well as the basic facts about vector spaces, basis, and algebras. Chapter 2 introduces tangent vectors and vector fields in IRⁿ using the standard two approaches with curves and derivations. Chapter 3 reviews linear transformations and their matrix representation so that in Chapter 4 the push-forward as an abstract linear transformation can be defined and its matrix representation as the Jacobian can be derived. As an application, the change of variable formula for vector …

Technology: An Essential Component Of Today's College Education, William F. Herlehy

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

The growing educational failures of the colleges and universities of the United States are a major concern of the 1990's and are not showing a great deal of promise for the 21st century. The overabundance of committee reports that describe and prescribe for our schools, the evidence presented in those reports, and the analyses that are offered combine to form a persuasive argument that there is a profound crisis (AACC, 1995).

Technological developments have so outpaced the understanding of it provided by almost all college programs that we have become a people who are unable to comprehend the technology we …
