Energy : converting from acoustic to biological resource units

Creator:: Benoit-Bird, Kelly J. and Au, Whitlow W. L.
Abstract:: Acoustic backscattering strength is often used as an index of biomass; however, the relationship between these variables has not been directly validated. Relationships were investigated between acoustic cross section at 200 kHz, measured as part of a previous study, and measured values of length, biovolume, dry weight, ash-free dry weight,...

Cooperative prey herding by the pelagic dolphin, Stenella longirostris

Creator:: Benoit-Bird, Kelly J. and Au, Whitlow W. L.
Abstract:: Sonar techniques were used to quantitatively observe foraging predators and their prey simultaneously in three dimensions. Spinner dolphins foraged at night in highly coordinated groups of 16–28 individuals using strict four-dimensional patterns to increase prey density by up to 200 times. Herding exploited the prey’s own avoidance behavior to achieve...

Climate-Driven Variability and Trends in Mountain Snowpack in Western North America

Creator:: Mote, Philip W.
Abstract:: Records of 1 April snow water equivalent (SWE) are examined here using multiple linear regression against reference time series of temperature and precipitation. This method permits 1) an examination of the separate roles of temperature and precipitation in determining the trends in SWE; 2) an estimation of the sensitivity of...

Diversity Literary Awards: A Tool for Assessing an Academic Library's Collection

Creator:: Kristick, Laurel L.
Abstract:: Diversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university. Gaps in the collection and acquisition processes were identified and will...

Global Existence and Energy Decay Rates for a Kirchhoff-Type Wave Equation with Nonlinear Dissipation

Creator:: Kim, Daewook, Kim, Dojin, Hong, Keum-Shik, and Jung, Il Hyo
Abstract:: The first objective of this paper is to prove the existence and uniqueness of global solutions for a Kirchhoff-type wave equation with nonlinear dissipation of the form Kuⁿ + 𝑀(|𝐴¹/²𝑢|²)𝐴𝑢 + 𝑔(𝑢')=0 under suitable assumptions on 𝐾, 𝐴, 𝑀(⋅), and 𝑔(⋅). Next, we under some growth conditions on the nonlinear...

Internal photoemission spectroscopy determination of barrier heights between Ta-based amorphous metals and atomic layer deposited insulators

Creator:: Jenkins, M. A., McGlone, J. M., Wager, J. F., and Conley, J. F., Jr.
Abstract:: The energy barrier heights between two recently reported Ta-based amorphous metals (TaWSi and TaNiSi), TaN, and atomic layer deposited Al2O3 and HfO2 insulators are measured in metal/insulator/metal (MIM) structures with Au top electrodes using internal photoemission (IPE) spectroscopy. For Al2O3, the Ta-based metal barrier heights, phi(Bn), increase with increasing metal...

Complex networks, streamflow, and hydrometric monitoring system design

Creator:: Halverson, M. J. and Fleming, S. W.
Abstract:: Network theory is applied to an array of streamflow gauges located in the Coast Mountains of British Columbia and Yukon, Canada. The goal of the analysis is to assess whether insights from this branch of mathematical graph theory can be meaningfully applied to hydrometric data, and more specifically, whether it...

Th-234 applied to particle removal rates from the surface ocean: A mathematical treatment revisited

Creator:: Alleau, Y., Colbert, D., Covert, P., Haley, Brian A., Qiu, X., Collier, Robert W., Falkner, Kelly, Hales, Burke, Prahl, Fredrick, and Gordon, L.
Abstract:: It has been recognized since the 1950's that radioisotopic disequilibrium between naturally occurring parent-daughter isotope pairs in seawater can provide information on the rate of processes segregating them. In the surface ocean, the U-238:Th-234 parent-daughter pair tends to display measurable disequilibrium that is attributable to the effects of scavenging on...

Enhancing the T-shaped learning profile when teaching hydrology using data, modeling, and visualization activities

Creator:: Sanchez, Christopher A., Ruddell, Benjamin L., Ruddell, Benjamin L., and Merwade, Venkatesh
Abstract:: Previous research has suggested that the use of more authentic learning activities can produce more robust and durable knowledge gains. This is consistent with calls within civil engineering education, specifically hydrology, that suggest that curricula should more often include professional perspective and data analysis skills to better develop the "T-shaped"...

A new instrument to measure plot-scale runoff

Creator:: Stewart, R. D., Liu, Z., Rupp, D. E., Higgins, C. W., and Selker, J. S.
Abstract:: Accurate measurement of the amount and timing of surface runoff at multiple scales is needed to understand fundamental hydrological processes. At the plot scale (i.e., length scales on the order of 1–10 m) current methods for direct measurement of runoff either store the water in a collection vessel, which is...
