Integration Of Plant-Based Canopy Sensors For Site-Specific Nitrogen Management, Luciano S. Shiratsuchi

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The soil’s nitrogen (N) supply can vary drastically in the field, spatially as well as temporally making any soil prediction difficult even with very detailed mapping. Consequently, a plant-based approach wherein the measured canopy can indicate the N needs in a reactive and spatially-variable way can be a better approach than mapping, because integrate the soil N supply and translate the crop need on-the-go. The first experiment evaluated the performance of various spectral indices for sensing N status of corn, where spectral variability might be confounded by water-induced variations in crop reflectance. We found that water and previous crops effects …

Optical Properties Of Antiferroelectric Cs2nb4o11: Absorption Spectra And First-Principles Calculations, H. L. Liu, C. R. Huang, G. F. Luo, Wai-Ning Mei

Chemistry Faculty Publications

We report a joint experimental and theoretical investigation of the optical properties of Cs2Nb4O11. In room temperature optical absorption spectra, we found a direct gap about 3.5560.05 eV and charge transfer excitations at about 4.96 and 6.08 eV, which are in good agreement with the first-principles calculations. Upon passing through the 165 C antiferroelectric to paraelectric phase transition, the peak energies of two charge transfer bands display almost no temperature dependence, yet they become even broader and exhibit enhanced oscillator strength. We infer this intriguing behavior as the manifestation of Nb cation distortions due to the charge-lattice interaction.

On-Line Banking Systems: Are They Sustainable?, Satish Mahadevan Srinivasan, Sachin Pawaskar, Abhishek Tripathi, Lotfollah Najjar

Information Systems and Quantitative Analysis Faculty Proceedings & Presentations

Although the trend for on-line banking has increased in recent years, the customers have not shown enthusiastic participation in the past and in present. Since the sustainability of a bank supporting on-line-banking service depends on what capacity it can attract new customers, retain already existing customers and how well can it extend its services to the current and future customer base. This investigation is focused on examining if there is any significant difference among the factors namely the transactional security, information design, navigational design, visual design, web site trust, web site satisfaction and e-loyalty over sustainability of on-line banking for …

Analysis Of 26" And 29" Wheel Mountain Bikes, Jacob Publicover, David Wang, Alex Warring

Mechanical Engineering

There are two major mountain bike diameter wheel sizes on the market today, but with two different options, one would naturally wonder, “Which one is best?” During the course of this project, 26 and 29 inch wheel mountain bikes were analyzed quantitatively and qualitatively, using a variety of test methods, from heart rate monitoring to serial data acquisition to computer simulated analyses; static, dynamic, theoretical, and subjective tests were administered.

Estimates Of Stress Drop And Crustal Tectonic Stress From The 27 February 2010 Maule, Chile, Earthquake: Implications For Fault Strength, Karen M. Luttrell, Xiaopeng Tong, David T. Sandwell, Benjamin A. Brooks, Michael G. Bevis

Faculty Publications

The great 27 February 2010 Mw 8.8 earthquake off the coast of southern Chile ruptured a ∼600 km length of subduction zone. In this paper, we make two independent estimates of shear stress in the crust in the region of the Chile earthquake. First, we use a coseismic slip model constrained by geodetic observations from interferometric synthetic aperture radar (InSAR) and GPS to derive a spatially variable estimate of the change in static shear stress along the ruptured fault. Second, we use a static force balance model to constrain the crustal shear stress required to simultaneously support observed fore-arc topography …

Is The Transition From Classical To Quantum Mechanics Truly An Example Of A Kuhnian Revolution?, Valia Allori

Faculty Articles, Papers, and Other Scholarship

I argue that classical mechanics and quantum theories are not necessarily as radically different as they have been depicted so far. In fact whether we actually have a paradigm shift going from classical to quantum mechanics is going to depend on what we understand quantum mechanics to be.

Influence Of Gas Pressure On High-Order-Harmonic Generation Of Ar And Ne, Guoli Wang, Cheng Jin, Anh-Thu Le, C. D. Lin

Physics Faculty Research & Creative Works

We study the effect of gas pressure on the generation of high-order harmonics where harmonics due to individual atoms are calculated using the recently developed quantitative rescattering theory, and the propagation of the laser and harmonics in the medium is calculated by solving the Maxwell's wave equation. We illustrate that the simulated spectra are very sensitive to the laser focusing conditions at high laser intensity and high pressure since the fundamental laser field is severely reshaped during the propagation. By comparing the simulated results with several experiments we show that the pressure dependence can be qualitatively explained. The lack of …

Part 1: Size-Independent Quantification Of Ligand Binding Site Depth In Receptor Proteins. Part 2: Representing Rod-Shaped Protein 3d Structures In Cylindrical Coordinates, Srujana Cheguri

Theses

Abstract 1 We have developed a web server that implements the two complementary methods to quantify the depth of ligand and/or ligand binding site (LBS) in a protein-ligand complex. The two methods are the `secant plane' (SP) and the `tangent sphere' (TS) methods. In the SP and TS methods, the protein molecular centroid (global centroid, GC), and the LBS centroid (local centroid, LC) are first determined. The SP is defined as the plane passing through the LBS centroid and normal to the line passing through the LC and the protein molecular centroid. The "exterior side" of the SP is the …

Residence Hall Sense Of Community In Physical And Technology-Based Spaces: Implications For Alcohol-Related Attitudes And Behaviors, Benjamin C. Graham

College of Liberal Arts & Social Sciences Theses and Dissertations

Social experiences such as sense of community (SOC) and peer norms have the potential to influence attitudes and behaviors around a host of wellness-related issues. Social interaction, facilitated by the rapid growth of communication technology, in addition to the enduring need to interact in physical space, represent important community features. College residence halls are of interest to community psychology and other fields, as they are highly interactive, technologically-rich contexts where communities occur. Peer norms having a strong relationship to students’ perspectives and choices around alcohol. Less understood is the role that SOC plays, and the forms of social interaction that …

Communication Disorders Faculty Publications

Haploinsufficiency of TBX1, encoding a T-box transcription factor, is largely responsible for the physical malformations in velo-cardio-facial /DiGeorge/22q11.2 deletion syndrome (22q11DS) patients. Cardiovascular malformations in these patients are highly variable, raising the question as to whether DNA variations in the TBX1 locus on the remaining allele of 22q11.2 could be responsible. To test this, a large sample size is needed. The TBX1 gene was sequenced in 360 consecutive 22q11DS patients. Rare and common variations were identified. We did not detect enrichment in rare SNP (single nucleotide polymorphism) number in those with or without a congenital heart defect. One exception …

Nonlinear Progressive Wave Equation For Stratified Atmospheres, B. Edward Mcdonald, Andrew A. Piacsek

All Faculty Scholarship for the College of the Sciences

The nonlinear progressive wave equation (NPE) [McDonald and Kuperman, J. Acoust. Soc. Am. 81, 1406–1417 (1987)] is expressed in a form to accommodate changes in the ambient atmospheric density, pressure, and sound speed as the time-stepping computational window moves along a path possibly traversing significant altitude differences (in pressure scale heights). The modification is accomplished by the addition of a stratification term related to that derived in the 1970s for linear range-stepping calculations and later adopted into Khokhlov-Zabolotskaya-Kuznetsov-type nonlinear models. The modified NPE is shown to preserve acoustic energy in a ray tube and yields analytic similarity solutions for …

The Evolution Of Function In Strictosidine Synthase-Like Proteins, Michael A. Hicks, Alan E. Barber, Lesley Ann Giddings, Jenna Caldwell, Sarah E. O'Connor, Patricia C. Babbitt

Chemistry: Faculty Publications

The exponential growth of sequence data provides abundant information for the discovery of new enzyme reactions. Correctly annotating the functions of highly diverse proteins can be difficult, however, hindering use of this information. Global analysis of large superfamilies of related proteins is a powerful strategy for understanding the evolution of reactions by identifying catalytic commonalities and differences in reaction and substrate specificity, even when only a few members have been biochemically or structurally characterized. A comparison of >2500 sequences sharing the six-bladed β-propeller fold establishes sequence, structural, and functional links among the three subgroups of the functionally diverse N6P superfamily: …

A Recognition-Based Motion Capture Baseline On The Humaneva Ii Test Data, Nicholas Howe

Computer Science: Faculty Publications

The advent of the HumanEva standardized motion capture data sets has enabled quantitative evaluation of motion capture algorithms on comparable terms. This paper measures the performance of an existing monocular recognition-based pose recovery algorithm on select HumanEva data, including all the HumanEva II clips. The method uses a physically-motivated Markov process to connect adajacent frames and achieve a 3D relative mean error of 8.9 cm per joint. It further investigates factors contributing to the error, and finds that research into better pose retrieval methods offers promise for improvement of this technique and those related to it. Finally, it investigates the …

The assessment asks both multiple-choice and open-ended questions in the areas of writing, reading and mathematics, and provides international normative information about student performance. The Reading and Mathematical Literacy are based on the internationally endorsed frameworks of the OECD's Programme for International Student Assessment (PISA). …

Characterizing Adaptive Capacity To Climate Change In Developing Countries: A Case Study On Peru, Rosa Mitsumasu Heredia

Theses

Climate change is expected to impact biodiversity, global temperatures and the water cycle resulting in changes that affect communities in the social system. The capacity to adapt to such climatic fluctuations will vary across social groups, depending on the group's socio-economic and demographic characteristics. This thesis constructs a methodology that bridges existing approaches to study adaptation, providing an alternative that includes high level deterministic approaches to quantify adaptive capacity (AC) and case-by-case strategies to enhance region-specific AC. The proposed methodology consists of an exploratory model and a principal component analysis. The goal of the methodology is to create a sub-national …

Environmental Impact Comparison Of Distributed And Centralized Manufacturing Scenarios, Lionel Senyana

Theses

Centralized manufacturing and distributed manufacturing are two fundamentally different methods for producing components. This work describes a centralized manufacturing scenario in which parts are produced via forging and finish machining at one central location and are then shipped to the end user. The distributed manufacturing model involves a scenario in which an additive manufacturing process (Electron Beam Melting) is used to produce parts to near net shape with minimal finish machining. Because the process doesn't require molds or dies, production can take place in small production quantities "on demand" at job shops located close to the end user with little …

The work visually investigates through a range of interdisciplinary projects issues related to the nature of the photographic medium and the functioning of the capitalist system. Tractatus uses systematic methodologies embedded in Conceptualism that focus on a more complex, more politicized and more critical understanding of photographs, interrogating the documentary use of the camera.

Combined Fluorescence And Reflectance Spectroscopy For In Vivo Quantification Of Cancer Biomarkers In Low- And High-Grade Glioma Surgery, Pablo A. ValdéS, Anthony Kim, Keith D. Paulsen, Frederic Leblond, Olga M. Conde, Brent T. Harris, David W. Roberts

Dartmouth Scholarship

Biomarkers are indicators of biological processes and hold promise for the diagnosis and treatment of disease. Gliomas represent a heterogeneous group of brain tumors with marked intra- and inter-tumor variability. The extent of surgical resection is a significant factor influencing post-surgical recurrence and prognosis. Here, we used fluorescence and reflectance spectral signatures for in vivo quantification of multiple biomarkers during glioma surgery, with fluorescence contrast provided by exogenously-induced protoporphyrin IX (PpIX) following administration of 5-aminolevulinic acid. We performed light-transport modeling to quantify multiple biomarkers indicative of tumor biological processes, including the local concentration of PpIX and associated photoproducts, total hemoglobin …

Design Of A Dynamic Activity Travel Modeling System For Metro, John Gliebe

Urban Studies and Planning Faculty Publications and Presentations

Trip-based models are no longer adequate for some of the more complex questions. They fail to account for time of day sensitivity, dynamic congestion effects, variable pricing and tolls, and the reliability of both highways and transit. Existing activity/tour-based models lack the enhanced temporal element provided by a more dynamic, activity-based microsimulation. DASH is the next-generation model being developed by the Metro Research Center.
