Temperature Index Modeling Of The Kahiltna Glacier: Comparison To Multiple Field And Geodetic Mass Balance Datasets, Joanna Young

Geosciences

Glaciers of Alaska, USA, and Northwestern Canada are shedding mass at one of the highest rates of any mountain glacier system, with significant impact at the global and local scales. Despite advances in satellite and airborne technologies, fully characterizing the temporal evolution of glacier mass change in individual watersheds remains a challenge. Temperature index modeling is an approach that can be used to expand on sparse ground observations, and that can help bridge the gap between regional and individual watershed estimates of the time series of glacier mass change. Here we present a study on temperature index modeling of glacier-wide …

Igneous Rocks And Structures Of The Nixon Fork Mine, Alaska, And Their Relations To Ores, Brian Perttu

Geosciences

The Nixon Fork Mine is a high-grade Cu-Au skarn deposit located near the western contact of the 5 square km Late Cretaceous Mystery pluton with marble, 7 km southeast of the Iditarod-Nixon Fork (I-NF) fault. This fault strikes at ~060�, and can be traced for ~400 km, with a minimum dextral displacement of ~90 km. Close proximity suggests that the Nixon Fork deposit should have been affected by the I-NF fault. In order to assess the structural evolution, I analyzed the orientations of geologic structures. I transcribed 1172 structures from previous mapping (to assess structures) and converted 186 maps into …

Satellite To Model Comparisons Of Volcanic Ash Emissions In The North Pacific, Torge S. Steensen

Geosciences

To detect, analyze and predict the movement of volcanic ash in real time, dispersion models and satellite remote sensing data are important. A combination of both approaches is discussed here to enhance the techniques currently used to quantify volcanic ash emissions, based on case studies of the eruptions of the Kasatochi (Alaska, USA, 2008), Mount Redoubt (Alaska, USA, 2009) and Sarychev Peak (Russia, 2009) volcanoes. Results suggest a quantitative approach determining masses from satellite images can be problematic due to uncertainties in knowledge of input values, most importantly the ground surface temperature required in the mass retrieval. Furthermore, a volcanic …

New Algorithms For The Compilation Of Glacier Inventories, Christian Kienholz

Geosciences

Glacier inventories are used for many applications in glaciology, however, their manual compilation is time-consuming. Here, we present two new algorithms for the automatic compilation of glacier inventories. The first approach is based on hydrological modeling tools and separates glacier complexes into individual glaciers, requiring a digital elevation model (DEM) and glacier complex outlines as input. Its application to > 60,000 km² of ice in Alaska (~98% success rate) and southern Arctic Canada (~97% success rate) indicates the method is robust if DEMs and glacier complex outlines of good quality are available. The second algorithm relies on glacier outlines and a …

Basal Shear Strength Inversions For Ice Sheets With An Application To Jakobshavn Isbræ, Greenland, Marijke Habermann

Geosciences

Satellite and in situ observations of ice sheet outlet glaciers around the turn of the 21st century showed that rapid changes in ice dynamics are possible and important for the evolution of ice sheets. When attempting to model these dynamic changes the conditions at the ice-bed interface are crucial. Inverse methods can be used to infer basal properties, such as the basal yield stress, from abundant surface velocity observations by using a physical model of ice flow. Inverse methods are very powerful, but they need to be applied with care, otherwise errors can dominate the solution. In this study we …

Seismicity, Seawater And Seasonality: New Insights Into Iceberg Calving From Yahtse Glacier, Alaska, Timothy Chester Bartholomaus

Geosciences

At many of the largest glaciers and ice sheets on Earth, more than half of the annual ice loss occurs through iceberg calving into the ocean. Calving is also responsible for the most rapid ice mass changes, both directly (through the mechanical loss of ice at the terminus) and indirectly (through dynamic thinning of upstream ice initiated by terminus retreat). Yet, the mechanisms and factors that control calving are poorly understood. Recordings of glaciogenic seismic waves, known as "icequakes," produced during iceberg calving offer opportunities for insight that cannot be gleaned through other methods. In order to better understand iceberg …

Feedbacks Based On Hyperspectral Measurements Of The Air-Sea Temperature Difference, Adam Chambers

Open Access Theses

Ship-based measurements of the air-sea temperature difference (air-sea ΔT) are analyzed and presented with a focus on the temperature difference probability distribution and causes of its stability and variability. By taking the measurements with a hyperspectral infrared radiometer, temperatures of both the lower atmosphere and the skin layer of the ocean are acquired by a single, well-calibrated instrument. Consider that for each radiometric cruise deployment, when the air-sea ΔT measurements are plotted in a histogram, a mean air-sea ΔT peak at about -1 K becomes apparent regardless of measurement location or time of year. The large amount of air-sea ΔT …

Issues Related To Combining Multiple Speciated Pm2.5 Data Sources In Spatio-Temporal Exposure Models For Epidemiology: The Npact Case Study, Sun-Young Kim, Lianne Sheppard, Timothy V. Larson, Joel Kaufman, Sverre Vedal

UW Biostatistics Working Paper Series

Background: Regulatory monitoring data have been the most common exposure data resource in studies of the association between long-term PM_2.5 components and health. However, data collected for regulatory purposes may not be compatible with epidemiological study.

Objectives: We aimed to explore three important features of the PM_2.5 component monitoring data obtained from multiple sources to combine all available data for developing spatio-temporal prediction models in the National Particle Component and Toxicity (NPACT) study.

Methods: The NPACT monitoring data were collected in an extensive monitoring campaign targeting cohort participants. The regulatory monitoring data were obtained from the Chemical Speciation …

Prediction Of Fine Particulate Matter Chemical Components For The Multi-Ethnic Study Of Atherosclerosis Cohort: A Comparison Of Two Modeling Approaches, Sun-Young Kim, Lianne Sheppard, Silas Bergen, Adam A. Szpiro, Paul D. Sampson, Joel Kaufman, Sverre Vedal

UW Biostatistics Working Paper Series

Recent epidemiological cohort studies of the health effects of PM_2.5 have developed exposure estimates from advanced exposure prediction models. Such models represent spatial variability across participant residential locations. However, few cohort studies have developed exposure predictions for PM_2.5 components. We used two exposure modeling approaches to obtain long-term average predicted concentrations for four PM_2.5 components: sulfur, silicon, and elemental and organic carbon (EC and OC). The models were specifically developed for the Multi-Ethnic Study of Atherosclerosis (MESA) cohort as a part of the National Particle Component and Toxicity (NPACT) study. The spatio-temporal model used 2-week average measurements …

Dog Behavior Co-Varies With Height, Bodyweight And Skull Shape, Paul D. Mcgreevy, Dana Georgevsky, Johanna Carrasco, Michael Valenzuela, Deborah L. Duffy, James A. Serpell

Eidonomy Collection

Dogs offer unique opportunities to study correlations between morphology and behavior because skull shapes and body shape are so diverse among breeds. Several studies have shown relationships between canine cephalic index (CI: the ratio of skull width to skull length) and neural architecture. Data on the CI of adult, show-quality dogs (six males and six females) were sourced in Australia along with existing data on the breeds’ height, bodyweight and related to data on 36 behavioral traits of companion dogs (n = 8,301) of various common breeds (n = 49) collected internationally using the Canine Behavioral Assessment and Research Questionnaire …

The Cult Of Salomé: Decapitation Imagery And Cultural Anxiety In Belle Époque Europe., Sean C. Hall

Master of Liberal Studies Theses

The Belle Époque in Europe marked a time of great change. Many of the old, yet longstanding traditions were being challenged and modernity really took hold of society at that time. The changes in the social fabric with issues such as the roles of women were common topics of conversation. Women demanded new rights and began to even question the role of masculinity in this new age. This was the emergence of the “New Woman,” and with all of these great changes came great anxiety. This cultural anxiety felt by many was expressed in the arts of the period which …

Direct Coupling Of Photonic Modes And Surface Plasmon Polaritons Observed In 2-Photon Peem, Robert Campbell Word, Joseph Fitzgerald, Rolf Könenkamp

Physics Faculty Publications and Presentations

We report the direct microscopic observation of optical energy transfer from guided photonic modes in an indium tin oxide (ITO) thin film to surface plasmon polaritons (SPP) at the surfaces of a single crystalline gold platelet. The photonic and SPP modes appear as an interference pattern in the photoelectron emission yield across the surface of the specimen. We explore the momentum match between the photonic and SPP modes in terms of simple waveguide theory and the three-layer slab model for bound SPP modes of thin metal films. We show that because the gold is thin (30- 40 nm), two SPP …

Department of Biological & Biomedical Sciences

Background

Cardiovascular disorders (CVDs) are the leading cause of disease burden worldwide. Apart from available synthetic drugs used in CVDs, there are many herbal formulations including POL-10 (containing 10 herbs), which have been shown to be effective in animal studies but POL-10 was found to cause tachycardia in rodents as its side effect. This study was designed to modify the composition of POL-10 for better efficacy and/or safety profile in CVDs.

Methods

To assess the antidyslipidemic, antihypertensive and endothelial modulatory properties of two herbal formulations, (ZPTO and ZTO) containing Z: Zingiber officinalis, P: Piper nigrum, T: Terminalia belerica and …

The Familial Union Between Caregivers And The Juvenile Justice System, Joshua T. Baldwin, Wesley Church, Tracy Wharton

Journal of Family Strengths

This research describes an initial exploration of the phenomenon of caregivers’ learning of their child’s detention, an area of exploration that has little previous attention in the literature. This initial exploration was rooted in a desire to gain an understanding of the caregiver’s experience with both their family member (adjudicated juvenile) and the criminal justice system. A qualitative, phenomenological approach was used in this study to gain rich understanding into the lived experiences shared by twelve caregivers of youth being adjudicated in the juvenile justice system. Two overarching themes emerged from the data: 1) the system, with communication, fairness, and …

Grammar In The Composition Classroom: Rewriting The Tradition, Debra Lynn Reece

Theses and Dissertations

In the last 50 years, the trend in the field of composition pedagogy has turned away from traditional grammar instruction, condemning pedagogical practices that focus on preventing and remediating error. In the early 1960s, Richard Braddock, Richard Lloyd-Jones, and Lowell Schoer invoked the death sentence on traditional grammar instruction: "The teaching of formal grammar has a negligible or, because it usually displaces some instruction and practice in actual composition, even a harmful effect on the improvement of writing" (37-38). Having been enlightened by this scholarship, the field refocused instruction to emphasize elements like writing process, collaboration, modeling, and prewriting, pushing …

Rapid Generation Of Light Beams Carrying Orbital Angular Momentum, Mohammad Mirhosseini, Omar S. Magaña-Loaiza, Changchen Chen, Brandon Rodenburg, Mehul Malik, Robert W. Boyd

Faculty Publications

We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerre-Gaussian and vortex orbital-angular-momentum (OAM) modes, along with modes in a set that is mutually unbiased with respect to the OAM basis. Additionally, we have demonstrated rapid switching among the generated modes at a speed of 4 kHz, which is much faster than the speed regularly achieved by phase-only spatial light modulators (SLMs). The dynamic control of both phase and amplitude of a laser beam is an enabling technology for classical communication and …

Reduced Row Echelon Form And Non-Linear Approximation For Subspace Segmentation And High-Dimensional Data Clustering, Akram Aldroubi, Ali Sekmen

Computer Science Faculty Research

Given a set of data W={w1,…,wN}∈RD drawn from a union of subspaces, we focus on determining a nonlinear model of the form U=⋃i∈ISi, where {Si⊂RD}i∈I is a set of subspaces, that is nearest to W. The model is then used to classify W into clusters. Our approach is based on the binary reduced row echelon form of data matrix, combined with an iterative scheme based on a non-linear approximation method. We prove that, in absence of noise, our approach can find the number of subspaces, their dimensions, and an orthonormal basis for each subspace Si. We provide a comprehensive analysis …

Comparison Of Corrosion Of Magnesium And Aluminium In Palm Biodiesel / Chew King Vee, King Vee Chew

Student Works (2010-2019)

Salat is an Islamic prayer ritual that all Muslims must perform five times a day. The salatphysical manoeuvres steps include various motions such as standing, bowing, prostration, and sitting. Recently, the study of salat movements from the perspective of science has been widely investigated. The current study evaluated the impact of salatmovements on the biomechanical response of human muscle using electromyography (EMG). The eight upper-bodymuscles involved were the neck extensors (NE), sternocleidomastoideus (SCM), trapezius (TRP), deltoid (DL), bicepsbrachii (BB), triceps brachii (TB), rectus abdominus (RA), and erector spine (ES) and the four lower-body muscles involved were the rectus femoris (RF), …
