The Use of Consumer Electronics as a Medium for Music Composition
Dean Shannon
The Nintendo Entertainment System produces sound through the Ricoh 2z03 microprocessor. This 8-bit processor is limited to creating two square-waves, a triangle-wave, and a noise track. While the 2a03 is limited, it is what gives the NES its distinctive and memorable sound.

Remote Sensing Risk Assessment of Valdez Glacier Lake
Erik Soederstroem
Can remote sensing techniques be used to determine the probability of an outburst from the Valdez Glacier Lake, and to detect downstream areas affected by a possible glacier lake outburst flood?

Rural Telemedicine in Alaska: A Look at Healthcare Through Telecommunications
Ethan Stephens
•An average town in the United States will have a basic medical facility capable of treating its patients. If not, there is roadway access to a capable facility. •In Rural Alaska however, there is no way to drive to the nearest hospital. These communities are not connected to the major road system and the only way to reach a hospital is by air transport. •Although many villages have access to hub communities that maintain a clinic, the clinic may not have the capabilities to treat certain ailments and many villages have no access to a medical facility. •Providing adequate medical care for Rural Alaskans is difficult due particularly to the size of Alaska, the geographic isolation of many villages, and to the cost of transportation to these rural areas. •The most serious healthcare issues that have been seen in Rural Alaska are “too few physicians or services and [health] care is too expensive,” (Hagopian et al, 2000). •In hopes of overcoming these obstacles in rural medicine, many organizations initiated telemedicine and telehealth programs.

Central CO2/pH Chemosensitivity Influence on Respiration in both Early and Late Staged Tadpoles
Alex Tackett
We test the hypothesis that central respiratory CO2/pH chemosensitivity, recorded from isolated brainstems, remains consistent throughout tadpole development. Results indicate that tadpoles at all developmental stages respond to CO2/pH, and that the sensitivity of these responses does not change with development.

Kern Canyon Fault Quartz Piezometry and Thermometry: How Weak are Rocks in a Deep Fault?
Rebekah Tsigonis
This project is an investigation of the strength of rocks from 10-25 kilometers depth in the Kern Canyon Fault in the Sierra Nevada. When this fault was active, it behaved similarly to the San Andreas Fault in California and the Denali Fault here in Alaska. Deep sections of this ancient fault were brought to the surface of the Earth through erosion. Using a method known as piezometry, I was able to measure the sizes of deformed quartz grains in rock samples, which inversely relates to the amount of stress that the rocks experienced during faulting. I also used a technique known as titanium-in-quartz thermometry (TitaniQ) to determine the temperature of the rocks during faulting deformation episodes. Via the Electron Microprobe in the Analytical Facility at UAF, I was able to measure the amount of titanium present in the deformed quartz grains which directly correlates to the temperature at which these crystals formed. In combining the calculations for stress and temperature of deformation, the strain rate exhibited on these rocks was determined which is used to better understand how weak or strong rocks are at different depths within fault zones.

The Flight of the Black Wolf Squadron
Benjamin Widman
By 1920, Alaska became economically, politically, and socially stale. Aviation brought a need revitalization to the territory. The Black Wolf Squadron's flight from New York to Nome brought international attention and promised new industries and commercial opportunities. The flight of the Black Squadron would begin a new era for Alaska, the era of aviation.

Characterizing Transitioning in Chaotic Models
A Winkelman
In order to understand how complicated physical systems behave, we study idealized systems instead and interpret the qualitative behavior. In order to understand how non-linear, chaotic systems transition into new parameter sets, we characterize the distribution of dynamical points over the manifold of trajectories (also known as the “strange attractor”) for the Lorenz model under two regimes. We consider the effects of variation of just one of the three parameters of the Lorenz model. First, we establish measures of shape of the distribution over the manifold for a range of static values of that parameter. Then, the same measures of shape are calculated for the trajectory that results when a parameter is ramped linearly in time. Statistical comparison of these distributions will be used to describe the evolution of the attractor. This simple model can illustrate how such non-linear, chaotic systems behave when the parameters of the system vary.

Frequency-Based Monitoring of Small-Scale Explosive Volcanic Activity
Anna K. Worden
Strombolian activity is one of the most common types of volcanic activity. When this activity occurs at remote volcanoes it often goes undetected and cannot be monitored easily or safely by direct methods. Satellite remote sensing can be useful in the routine monitoring of this activity. Numerous remote volcanoes in the North Paci c exhibit Strombolian activity, often as a precursor to more vigorous activity which can a ect communities and transportation. Factors a ecting the visibility the explosions include satellite and crater geometry, time of image capture, and most importantly, weather. These factors eliminate a signi cant number of satellite passes. The remaining passes are used to calculate the probability of a clear view at the volcano and the likelihood of detecting an explosion. All of these factors are used to detect changes in relative frequency of explosions.
