2009 1m Snow Depth For Reynolds Mountain East, Reynolds Creek Experimental Watershed, Idaho, Rupesh Shrestha

Boise Center Aerospace Laboratory Data

Snow depth was calculated for the general area of Reynolds Mountain East in Reynolds Creek Experimental Watershed using lidar data collected in November 10-18, 2007 (snow off) and March 19, 2009 (snow on). The raw point clouds were filtered using the BCAL Lidar Tools and then 2007 and 2009 point clouds were georeferenced to each other. The point clouds were then rasterized to 1 m and the 2007 bare earth raster was subtracted from the 2009 snow on raster to create a 1 m snow depth product.

We consider the conjugacy problem for the automorphism groups of a number of countable homogeneous structures. In each case we find the precise complexity of the conjugacy relation in the sense of Borel reducibility.

An Experiment-Based Methodology To Understand The Dynamics Of Group Decision Making, Susan G. Mason, Don Holley, Aaron Wells, Amit Jain, Thomas Wuerzer, Alark Joshi

Urban Studies and Community Development Faculty Publications and Presentations

In this paper, we present an experiment-based design to examine the dynamics of group decision making. The experiment-based design on group decision making that we put forth provides a path for understanding collective decision making. Understanding more about the dynamics of collective decision making will benefit public policy making and design of roundtable discussions, which can enhance communication and cooperation on important issues such as the design and placement of transportation infrastructure, hospitals facilities, and housing for the homeless, and many others.

Impact Of Spatial Averaging On Radar Reflectivity At Internal Snowpack Layer Boundaries, N. Rutter, H.P. Marshall, K. Tape, R. Essery, J. King

CGISS Publications and Presentations

Microwave radar amplitude within a snowpack can be strongly influenced by spatial variability of internal layer boundaries. We quantify the impact of spatial averaging of snow stratigraphy and physical snowpack properties on surface scattering from near-nadir frequency-modulated continuous- wave radar at 12–18 GHz. Relative permittivity, density, grain size and stratigraphic boundaries were measured in-situ at high resolution along the length of a 9 m snow trench. An optimal range of horizontal averaging (4–6 m) was identified to attribute variations in surface scattering at layer boundaries to dielectric contrasts estimated from centimetre-scale measurements of snowpack stratigraphy and bulk layer properties. Single …

A Validated Software Application To Measure Fiber Organization In Soft Tissue, Erica E. Morrill, Azamat N. Tulepbergenov, Christina J. Stender, Roshani Lamichhane, Raquel J. Brown, Trevor J. Lujan

Mechanical and Biomedical Engineering Faculty Publications and Presentations

The mechanical behavior of soft connective tissue is governed by a dense network of fibrillar proteins in the extracellular matrix. Characterization of this fibrous network requires the accurate extraction of descriptive structural parameters from imaging data, including fiber dispersion and mean fiber orientation. Common methods to quantify fiber parameters include fast Fourier transforms (FFT) and structure tensors, however, information is limited on the accuracy of these methods. In this study, we compared these two methods using test images of fiber networks with varying topology. The FFT method with a band-pass filter was the most accurate, with an error of 0.71 …

Understanding How Algorithms Work Persuasively Through The Procedural Enthymeme, Kevin Brock, Dawn Shepherd

English Literature Faculty Publications and Presentations

Procedure, when discussed in regards to rhetoric, and to “digital rhetoric” in particular, is framed overwhelmingly in regards to game play (and to video games most frequently). We argue that this view needs to be expanded if scholars of rhetoric are to realize how complex human-computer rhetor systems function in diverse contexts. Such systems do so through procedural enthymemes, which persuade audience agents to action through the apparent logic of a given system. Procedural persuasion occurs most often via strategies that facilitate the agent to assume an active role in “self-persuasion” in order to complete a given enthymeme. In …

The Effects Of High Concentrations Of Ionic Liquid On Gb1 Protein Structure And Dynamics Probed By High-Resolution Magic-Angle-Spinning Nmr Spectroscopy, Lisa Warner, Erica Gjersing, Shelby E. Follett, K. Wade Elliott, Sergei V. Dzyuba, Krisztina Varga

Biomolecular Research Center Publications and Presentations

Ionic liquids have great potential in biological applications and biocatalysis, as some ionic liquids can stabilize proteins and enhance enzyme activity, while others have the opposite effect. However, on the molecular level, probing ionic liquid interactions with proteins, especially in solutions containing high concentrations of ionic liquids, has been challenging. In the present work the ¹³C, ¹⁵N-enriched GB1 model protein was used to demonstrate applicability of high-resolution magic-angle-spinning (HR-MAS) NMR spectroscopy to investigate ionic liquid–protein interactions. Effect of an ionic liquid (1-butyl-3- methylimidazolium bromide, [C₄-mim]Br) on GB1was studied over a wide range of the ionic liquid …

Closed Primary, Exposed Preferences: Idaho's Primary System And The Bureaucratic Dilemma, Matthew Ryan May

Boise State University Theses and Dissertations

The ability to elect representatives is one of the most fundamental rights citizens of the United States of America possess, but the expression of that right looks very different from state to state. A state’s primary system determines not only who participates in an election, but under what circumstances. When a state shifts from one primary system to another, it produces a period of uncertainty, as the electorate must acclimate to new rules and their attendant consequences. Among those who must adjust to the new rules are public state employees—the bureaucracy. When a shift necessitates and introduces a partisan …

Developing An Abac-Based Grant Proposal Workflow Management System, Milson Munakami

Boise State University Theses and Dissertations

In the advent of the digital transformation, online business processes need to be automated and modeled as workflows. A workflow typically involves a sequence of coordinated tasks and shared data that need to be secured and protected from unauthorized access. In other words, a workflow can be described simply as the movement of documents and activities through a business process among different users. Such connected flow of information among various users with different permission level offers many benefits along with new challenges. Cyber threats are becoming more sophisticated as skilled and motivated attackers both insiders and outsiders are equipped with …

Using Near-Infrared Photography To Better Study Snow Microstructure And Its Variability Over Time And Space, Jesse Raymond Dean

Boise State University Theses and Dissertations

The methods typically used to study snow stratigraphy, microstructure, and variability are expensive, cumbersome, and often highly subjective. Near-infrared (NIR) photography is a low-cost, portable tool to rapidly collect high-resolution, objective measurements of snow microstructure and variability. To expand its application, an active-source NIR flash was introduced to the traditionally passive-source method. NIR imagery was collected alongside proven snowpit methods such as manual observation, Snow Fork wetness, and Snow Micro-Penetrometer hardness profiles. NIR photography was also deployed in five pits along a 10.6 km transect in Grand Mesa, CO, to track stratigraphy variations in space. The NIR flash was found …

Continuous Snow Water Equivalent Measurements With Ultra-Wideband Radar: Towards A New Generation Of Real-Time Automated Snow Sensor Arrays, Mark Edward Robertson

Boise State University Theses and Dissertations

Snow accounts for the majority of precipitation in many areas of the Western United States, and accurate measurements of the amount of water contained in the snowpack, known as snow water equivalent (SWE), are therefore important for water resource managers. The National Resources Conservation Service Snow Telemetry (SNOTEL) sites are the current standard remote measurement of SWE, with approximately 800 sites across the Western United States. Measurements at these sites are made by snow pillows, which weigh the overburden pressure of a snowpack, and are relatively expensive to install and maintain. Spring runoff is modeled using a 30-year average of …

Two-Way Symmetric Communication Between Public Utilities And The Public, Maria Willacy

Differences between two-way symmetric communication and other communication/public relations methods are examined, as well as the specific merits of two-way symmetric communication, including its ethical benefits, and criticisms and constraints. Current forms of communication between public utilities and the public are examined, including whether these forms are two-way symmetric. Planning events and those that involve public participation are highlighted as …

Controls On The Presence, Concentration, Storage, And Variability Of Soil Inorganic Carbon In A Semi-Arid Watershed, Christopher Allen Stanbery

Boise State University Theses and Dissertations

Soil inorganic carbon (SIC) constitutes approximately 40% of terrestrial soil carbon and is an integral part of the global carbon cycle; however, the controls on the storage and flux of inorganic carbon are poorly understood. Soil forming factors controlling SIC storage and flux include climate, organisms, relief, parent material, and time (Jenny, 1941). Rainfall is a primary factor controlling SIC accumulation in arid and semi-arid regions, but the hierarchy of controls on SIC development is complex. The Reynolds Creek Experimental Watershed in southwestern Idaho is an ideal location to study factors influencing SIC, as the carbon pool transitions from predominately …

Using Infrasound Waves To Monitor Tropospheric Weather And Crater Morphology Changes, Hugo David Ortiz

Boise State University Theses and Dissertations

Infrasound waves generated during volcanic eruptions and recorded near the vent are used to study both changing atmospheric conditions and volcano eruption source characteristics. Infrasound data were recorded for a 32 month period at Volcán Tungurahua (Ecuador) by a five-station network located within 6.5 km from the vent. Infrasound detections made through cross-network correlation indicate cyclic eruptive behavior, which is corroborated by reports from the Ecuadorian monitoring agency. Cross-network correlation lag times are used to compute _10 m resolution infrasound source positions, which take into account NOAA models of local wind and temperature. Variable infrasound-derived source locations suggests source migration …

Towards Multipurpose Readability Assessment, Ion Madrazo

Boise State University Theses and Dissertations

Readability refers to the ease with which a reader can understand a text. Automatic readability assessment has been widely studied over the past 50 years. However, most of the studies focus on the development of tools that apply either to a single language, domain, or document type. This supposes duplicate efforts for both developers, who need to integrate multiple tools in their systems, and final users, who have to deal with incompatibilities among the readability scales of different tools. In this manuscript, we present MultiRead, a multipurpose readability assessment tool capable of predicting the reading difficulty of texts of varied …

Examining The Influence Of Number Line Fraction Task Characteristics On Student Work, Sharlee Hatch

Boise State University Theses and Dissertations

Research supports the claim that classrooms with teachers who respond to student thinking in the mathematics classroom will see greater student gains and student success (Lamon, 1996; Sleep & Boerst, 2012). The topic of fractions is both difficult to teach and learn, but has important implications on future success in mathematics and in life. This study set out to explore the ways in which student work is influenced by characteristics of number line fraction tasks. By examining task type, number line structure, and number choice this study shares the way these task characteristics influenced student strategies. The relationship between task …

Selling Narratives Of A Mexico In Crisis: Environmental Reporting In Excélsior And Uno Más Uno, 1983-84, Adam Behrman

Boise State University Theses and Dissertations

This thesis analyzes the diverse environmental narratives found in more than 200 stories published by two Mexican national newspapers, Excélsior and Uno Más Uno, in 1983 and 1984, a period of economic and environmental crisis. It argues that the popularity of environmental issues permitted column space for journalists, environmentalists, researchers, rural peasants, the urban poor, and government administrators to present their many different environmental narratives for the reading public’s consideration. Focusing on how journalists and their sources described air pollution, forests, and water crises in the pages of Excélsior and Uno Más Uno, this thesis brings out many …

Evaluating The Effects Of Major Assumptions In Layered Elastic Theory On Railroad Track Response Prediction Through The Development Of An Improved Track Analysis Software, Sadichchha Sharma

Boise State University Theses and Dissertations

Railway transportation has been recently gaining popularity due to its efficiency and environmental-friendly technology which has led to its increased usage for both passenger and freight transport. For railway transport to be a sustainable component of the transportation infrastructure in the United States, adequate structural and functional design of track components is essential. This is primarily dependent on thorough understanding of track mechanics and track structural response under loading, and can be accomplished through mechanistic analysis of railway track structure response under loading. Considering the need for a mechanistic track analysis program that can serve as a link between the …

Barn Owls (Tyto Alba) Crossing The Road - Examining The Interplay Among Occupancy, Behavior, Habitat Selection, And Roadway Mortality In Southern Idaho, Tempe Regan

Boise State University Theses and Dissertations

Barn Owls (Tyto alba) are killed by vehicle collisions in greater numbers than any other North American bird of prey. Interstate-84 (I-84) in southern Idaho, USA has among the world’s highest known rates of Barn Owl-vehicle collisions. Little is known about Barn Owl occupancy in this region, so it is unclear if owls are killed in proportion to their abundance, or if they are equally abundant in segments with lower mortality and somehow escape collisions. Furthermore, studies of Barn Owl movements and behavior are limited. I was interested in understanding (1) factors that affect Barn Owl occupancy in …

Kinetic Control Of Nucleic Acid Strand Displacement Reactions, Xiaoping Olson

Boise State University Theses and Dissertations

Nucleic acids are information-dense, programmable polymers that can be engineered into primers, probes, molecular motors, and signal amplification circuits for computation, diagnostic, and therapeutic purposes. Signal amplification circuits increase the signal-to-noise ratio of target nucleic acids in the absence of enzymes and thermal cycling. Amplification is made possible via toehold mediated strand displacement – a process where one nucleic acid strand binds to a nucleation site on a complementary helix, which then displaces one of the two strands in a nucleic acid complex. When compared to polymerase chain reactions (PCR), the sensitivity and stability of toehold-mediated strand displacement reactions suffer …

To Boldly Go: Boldness Predicts Behavior And Survivorship Of A Critical Prey Species, Zoe Katherine Tinkle

Boise State University Theses and Dissertations

Understanding population dynamics is at the core of conservation biology. However, our understanding of the mechanisms driving population dynamics remains unclear in many cases. Animal behavior in response to biotic and abiotic stressors is an important driver of these population dynamics and varies both within- and among-individuals in a population. Consistent differences in behavior among individuals within a population are referred to as personality traits. Boldness, a personality trait representing the willingness of an individual to engage in risky behavior, may help predict individual and community-level consequences, such as survivorship. Here, we investigated the inter- and intra-individual variation in risk-taking …

Empirical Models For Structural Effects Of A-Site Point Defects And Ordering In Perovskites, Kevin Ross Tolman

Boise State University Theses and Dissertations

Composition-structure-property relationships are essential keys to unlocking the strength of predictive crystal chemistry. Awkwardly, the electroceramics industry largely relies on various time-consuming and expensive trial-and-error experiments to address new questions which often could otherwise be interpolated from published data. Indeed, predictive models, which can be derived from empirical evidence, can greatly aid the direction and support of future development in a meaningful, apt, and cost-effective way. Theory suggests that intrinsic properties on the scale of a unit cell may be estimated from the sizes and charges of the chemical constituents alone. Ultimately, researchers could be provided a compositional recipe for …

Analog Spiking Neuromorphic Circuits And Systems For Brain- And Nanotechnology-Inspired Cognitive Computing, Xinyu Wu

Boise State University Theses and Dissertations

Human society is now facing grand challenges to satisfy the growing demand for computing power, at the same time, sustain energy consumption. By the end of CMOS technology scaling, innovations are required to tackle the challenges in a radically different way.

Such a neuromorphic chip that combines CMOS analog spiking neurons and nanoscale resistive random-access memory (RRAM) using as electronics synapses can provide massive neural network parallelism, high density and online learning capability, and hence, paves …

Evaluating The Suitability Of Microbial Induced Calcite Precipitation Technique For Stabilizing Expansive Soils, Sikha Neupane

Boise State University Theses and Dissertations

Expansive soils, also known as swell-shrink soils have been a problem for civil infrastructures including roads and foundations from ancient times. The use of chemical additives such as cement and lime to stabilize expansive soils is a common practice among geotechnical engineers especially for lightly loaded structures. However, several occurrences of subgrade failures were observed after stabilizing with chemical additives hence engineers are in search of sustainable stabilization alternatives. Microbial Induced Calcite Precipitation (MICP) is gaining attention as an environmental friendly soil improvement technique. Several researchers have successfully tested its feasibility in mitigating liquefaction induced problems in sandy soils. This …

Coupled Numerical Analysis Of Variations In The Capacity Of An Energy Pile In Clay Soil, Daniel Patrick Zimmerman

Boise State University Theses and Dissertations

Energy piles are an emerging alternative for the reduction of energy consumption to heat and cool buildings. The majority of the research to date focuses on thermodynamic properties or axial strain of piles. This paper concerns the effects of temperature fluctuation on the capacity of driven energy piles in clayey soils. Consolidation of clay (due to the dissipation of excess pore-water pressure in clay) surrounding piles affects the capacity of the pile (pile setup in clay). Reciprocally, it is reasonable to assume that heating and cooling periods will create or relax the excess pore-water pressure (EPWP) in clayey soils (due …

Using importance-performance analysis can assist with the instructional design of the activities. This exploratory study used importance-performance analysis in an online introduction to criminology course. There is limited research on experiential learning in online courses as well as empirical data to assist with the instructional design of the experiential learning activities. The primary goal of this article is to demonstrate the use of importance- performance analysis to guide the instructional design of experiential learning activities.

Pulse Shape And Timing Dependence On The Spike-Timing Dependent Plasticity Response Of Ion-Conducting Memristors As Synapses, Kris A. Campbell, Kolton T. Drake, Elisa H. Barney Smith

Electrical and Computer Engineering Faculty Publications and Presentations

Ion-conducting memristors comprised of the layered materials Ge₂Se₃/SnSe/Ag are promising candidates for neuromorphic computing applications. Here, the spike-timing dependent plasticity (STDP) application is demonstrated for the first time with a single memristor type operating as a synapse over a timescale of 10 orders of magnitude, from nanoseconds through seconds. This large dynamic range allows the memristors to be useful in applications that require slow biological times, as well as fast times such as needed in neuromorphic computing, thus allowing multiple functions in one design for one memristor type—a “one size fits all” approach. This work also …
