Goomig Farmlands Development Baseline Water Quality In The Lower Keep River, D L. Bennett, Richard J. George Dr

Resource management technical reports

In 2008 the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain. By mid-2014 construction of almost all of the water supply, drainage, access, monitoring and other infrastructure for the 7400ha Goomig Farmlands development had substantially been completed. An important concern is the effect the Goomig Farmlands development may have on the water quality of the downstream lower Keep River aquatic environment, particularly as it relates to threatened species that inhabit or may inhabit the area. Possible increases in salinity, nutrients, suspended sediment, heavy metals and farm chemicals delivered in …

New to the list are a chapter from Cindy Carlson’s Family Assessment, a book in the Buros-Nebraska Series on Measurement and Testing. Also crashing the top list are several articles from Library Philosophy & Practice, which has got to be among the most widely read scholarly …

A Potential Foundation For Emergent Space-Time, Kevin H. Knuth, Newshaw Bahreyni

Physics Faculty Scholarship

We present a novel derivation of both the Minkowski metric and Lorentz transformations from the consistent quantification of a causally ordered set of events with respect to an embedded observer. Unlike past derivations, which have relied on assumptions such as the existence of a 4-dimensional manifold, symmetries of space-time, or the constant speed of light, we demonstrate that these now familiar mathematics can be derived as the unique means to consistently quantify a network of events. This suggests that space-time need not be physical, but instead the mathematics of space and time emerges as the unique way in which an …

Manifest Complexity: A Foundational Ethic For Astrobiology?, Kelly C. Smith

Publications

This paper examines the age old question of the basis of moral value in the new context of astrobiology, which offers a fresh perspective. The goal is to offer the broad outline of a general theory of moral value that can accommodate the diversity of living entities we are likely to encounter beyond the confines of Earth. It begins with ratiocentrism, the view that the possession of reason is the primary means by which we differentiate entities having moral value in and of themselves from those having moral value merely by virtue of the uses to which they can be …

Asymptotically Optimal Algorithm For Checking Whether A Given Vector Is A Solution To A Given Interval-Quantifier Linear System, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical situations, we have a linear dependence between different quantities. In such situations, we often need to solve the corresponding systems of linear equations. Often, we know the parameters of these equations with interval uncertainty. In this case, depending on the practical problem, we have different notions of a solution. For example, if we determine parameters from observations, we are interested in all the unknowns which satisfy the given system of linear equations for some possible values of the parameters. If we design a system so that it does not exceed given tolerance bounds, then we need to …

Is The World Itself Fuzzy? Physical Arguments For -- And Unexpected Computational Consequences Of -- Zadeh's Vision, Vladik Kreinovich, Olga Kosheleva

Departmental Technical Reports (CS)

Fuzzy methodology has been invented to describe imprecise ("fuzzy") human statements about the world, statements that use imprecise words from natural language like "small" or "large". Usual applications of fuzzy techniques assume that the world itself is ``crisp'', that there are exact equations describing the world, and fuzziness of our statements is caused by the incompleteness of our knowledge. But what if the world itself is fuzzy? What if there is no perfect system of equations describing the physical world -- in the sense that no matter what system of equations we try, there will always be cases when this …

Death Patterns During The 1918 Influenza Pandemic In Chile, Gerardo Chowell, Lone Simonsen, Jose Flores, Mark A. Miller, Cecile G. Viboud

Global Health Faculty Publications

Scarce information about the epidemiology of historical influenza pandemics in South America prevents complete understanding of pandemic patterns throughout the continent and across different climatic zones. To fill gaps with regard to spatiotemporal patterns of deaths associated with the 1918 influenza pandemic in Chile, we reviewed archival records. We found evidence that multiple pandemic waves at various times of the year and of varying intensities occurred during 1918-1921 and that influenza-related excess deaths peaked during July-August 1919. Pandemic-associated mortality rates were elevated for all age groups, including for adults >50 years of age; elevation from baseline was highest for young …

Workspace Analysis Of A Linear Delta Robot: Calculating The Inscribed Radius, Michael Louis Pauly

Graduate Theses - Mechanical Engineering

One of the most important traits of a robotic manipulator is its work envelope, the space in which the robot can position its end effector. Parallel manipulators, while generally faster, are restricted by smaller work envelopes [1]. As such, understanding the parameters defining a physical robot’s work envelope is essential to the optimal design, selection, and use of robotic parallel manipulators. A Linear Delta Robot (LDR) is a type of parallel manipulator in which three prismatic joints move separate arms which connect to a single triangular end plate [2]. In this study, general inverse kinematics were derived for a linear …

The Theory Of Agricultural Cooperatives: A Neoclassical Primer, Jeffrey S. Royer

Department of Agricultural Economics: Faculty Publications

This monograph provides an introduction to the neoclassical theory of agricultural cooperatives. The neoclassical theory of cooperatives has been useful for generating insights into the behavior of cooperatives in various market structures, helping cooperatives develop business strategies consistent with their objectives, and informing public policy decisions concerning cooperatives. This monograph describes the application of neoclassical theory to farm supply and marketing cooperatives within various market structures in both the short and long run. Topics covered include the stability of cooperative price and output solutions, strategies for reducing the cost of producing a farm input sold to members and for raising …

Trade And Divergence In Education Systems, Fali Huang, Pao-Li Chang

Research Collection School Of Economics

This article presents a theory on the endogenous choice of education policy and the two-way causal relationship between trade and education systems. A country’s education system determines its talent distribution and comparative advantage; the possibility of trade by raising the returns to the sector of comparative advantage in turn induces countries to further differentiate their education systems and reinforces the initial pattern of comparative advantage. Specifically, the Nash equilibrium choice of education systems by two countries interacting strategically are necessarily more divergent than their autarky choices, and yet less than what is socially optimal for the world.

Calmodulin Enhances Ribbon Replenishment And Shapes Filtering Of Synaptic Transmission By Cone Photoreceptors., Matthew J. Van Hook, Caitlyn M. Parmelee, Minghui Chen, Karlene M. Cork, Carina Curto, Wallace B. Thoreson

Journal Articles: Pharmacology & Experimental Neuroscience

At the first synapse in the vertebrate visual pathway, light-evoked changes in photoreceptor membrane potential alter the rate of glutamate release onto second-order retinal neurons. This process depends on the synaptic ribbon, a specialized structure found at various sensory synapses, to provide a supply of primed vesicles for release. Calcium (Ca(2+)) accelerates the replenishment of vesicles at cone ribbon synapses, but the mechanisms underlying this acceleration and its functional implications for vision are unknown. We studied vesicle replenishment using paired whole-cell recordings of cones and postsynaptic neurons in tiger salamander retinas and found that it involves two kinetic mechanisms, the …

Probe Location Within Interfacial Layer Of Ctab Reverse Micelle System, Jonathan Li, Bridget L. Gourley

Annual Student Research Poster Session

To understand the chemistry of the interfacial region of reverse micelles (RM), we studied RM system made with the cationic surfactant cetyltrimethylammonium bromide (CTAB), alkanol cosurfactants dissolved in cyclohexane with water core. Spectroscopic methods, specifically UV-Vis absorption of Coumarin 343 (C343) as a probe molecule, were used to determine basic properties of RM systems. However, the probe location was difficult to determine because the spectrum (absorbance), when dissolved in RM solution, didn’t match the spectra in any of the pure components. Our data suggests that the interfacial layer of RM cannot be thought of behaving only the characteristic of single …

Dynamical Behavior Of Probe Molecules And Dominant Role Of Cosurfactants In Reverse Micelles, Jia Qi, Bridget L. Gourley

Annual Student Research Poster Session

Reverse micelles (RM) are nanopools of water surrounded by surfactant molecules in a non-polar solvent. Our studies investigated properties of RM probe molecules in the interfacial boundary between water and non-polar solvents. Reichardt’s dye, a probe molecule, was used to uncover properties of RM. UV/vis spectroscopy of Reichardt’s dye reveals information about polarity and the dye’s approximate residential location and also helps confirm molecular orbital energy diagram. We discovered an interesting phenomenon with Reichardt’s dye in RM. Surprisingly, the UV/vis spectrum of Reicahrdt’s dye in CTAB RM with octanol as a cosurfactant exhibits decreasing absorbance and a blue shift. Reichardt’s …

Nonlinear Optimal Filter Technique For Analyzing Energy Depositions In Tes Sensors Driven Into Saturation, B. Shank, J. J. Yen, Blas Cabrera, J. M. Kreikebaum, R. Moffatt, P. Redl, Betty A. Young, P. L. Brink, M. Cherry, A. Tomada

Physics

We present a detailed thermal and electrical model of superconducting transition edge sensors (TESs) connected to quasiparticle (qp) traps, such as the W TESs connected to Al qp traps used for CDMS (Cryogenic Dark Matter Search) Ge and Si detectors. We show that this improved model, together with a straightforward time-domain optimal filter, can be used to analyze pulses well into the nonlinear saturation region and reconstruct absorbed energies with optimal energy resolution.

Path Flow Estimator For Planning Applications In Small Communities, Seungkyu Rya, Anthony Chen, H. Michael Zhang, Will Recker

Graduate Student Publications

This paper presents an alternative planning framework to model and forecast network traffic for planning applications in small communities, where limited resources debilitate the development and applications of the conventional four-step travel demand forecasting model. The core idea is to use the path flow estimator (PFE) to estimate current and forecast future traffic demand while taking into account of various field and planning data as modeling constraints. Specifically, two versions of PFE are developed: a base year PFE for estimating the current network traffic conditions using field data and planning data, if available, and a future year PFE for predicting …

Search For Standard Model Production Of Four Top Quarks In The Lepton + Jets Channel In Pp Collisions At S√=8 Tev, The Cms Collaboration, V. Khachatryan, A. M. Sirunyan, Marc M. Baarmand, Marcus Hohlmann, Himali Kalakhety, Francisco Yumiceva

Aerospace, Physics, and Space Science Faculty Publications

A search is presented for standard model (SM) production of four top quarks (t¯tt¯t) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb−1 recorded at a centre-of-mass energy of 8TeV with the CMS detector at the CERN LHC. The expected cross section for SM t¯tt¯t production is SM t¯tt¯t 1 fb. A combination of kinematic reconstruction and multivariate techniques is used to distinguish between the small signal and large background. The data are consistent with expectations of the SM, and an upper limit of 32 fb is set at a …

The Effects Of An Extended Power Plant Shutdown On The Florida Manatee (Trichechus Manatus Latirostris) In Port Everglades, Florida, Christopher Grissett

HCNSO Student Theses and Dissertations

Florida manatees (Trichechus manatus latirostris) seek out warmer waters during winter months when ambient water temperatures drop below 20 degrees Celsius. Over time, manatees have discovered artificial warm water sites from power plant discharges in addition to natural sites such as springs and passive thermal refugia (PTRs). The Florida Power and Light (FPL) Port Everglades power plant in Broward County is one such artificial warm water refuge used by manatees. This plant was shutdown on July 16, 2013, and is expected to remain off line for at least three years during demolition and construction of a new facility. …

Habitat And Seasonal Distribution Of The North American River Otter (Lontra Canadensis) And Vertebrate Species Assemblages In Two Protected Areas Of The Florida Everglades, Catherine Faye Hamilton

HCNSO Student Theses and Dissertations

The Florida Everglades ecosystem is threatened by human development, increased pollution, freshwater scarcity, and invasive species; factors that have negatively impacted the Everglades and native species health and populations. Man-made canals and levies have redirected the natural flow of fresh water from Lake Okeechobee into the Florida Everglades, starving central and south Florida ecosystems of necessary fresh water and nutrients. Through the efforts of the Comprehensive Everglades Restoration Project (CERP), freshwater is being redirected back into central and south Florida, returning the sheet flow of water back into the Everglades. Monitoring species abundance in the Everglades is a beneficial conservational …

Reduction Of The Long-Term Inaccuracy From The Avhrr–Based Ndvi Data, Md Zahidur Rahman, Leonid Roytman, M. Nazrul Islam

Publications and Research

This paper investigated the normalized difference vegetation index (NDVI) stability in the NOAA/NESDIS Global Vegetation Index (GVI) data during 1982-2003, which was collected from five NOAA series satellites. An empirical distribution function (EDF) was developed to eliminate the long-term inaccuracy of the NDVI data derived from the AVHRR sensor on NOAA polar orbiting satellite. The instability of data results from orbit degradation as well as from the circuit drifts over the life of a satellite. Degradation of NDVI over time and shifts of NDVI between the satellites were estimated using the China data set, because it includes a wide variety …

Poster: Protecting Against Data Exfiltration Insider Attacks Through Application Programs, Asmaa Mohamed Sallama, Elisa Bertino

Cyber Center Publications

In this paper, we describe a system that distinguishes be- tween legitimate and malicious database transactions per- formed by application programs. Our system is particularly useful for protecting against code-modification attacks performed by insiders who have access to and can change the programs' source code to make them execute different queries than those they are expected to execute. Our system works with any type of DBMS and requires minimum modification to application programs.

The Effect Of Students' Mathematical Beliefs On Knowledge Transfer, Kristen Adams

Theses and Dissertations

Students learn many different concepts throughout their mathematical careers. In order to be successful in mathematics, students should be able to transfer these mathematical concepts learned in one situation and apply them to a new situation. There are many factors that might affect how students transfer knowledge; however research has focused mostly upon cognitive factors, even though affective factors might also exhibit a strong influence. This study examined how students' mathematical beliefs, specifically beliefs about mathematics education and self-efficacy, affect the transfer process. Data were collected from three middle school students. These data were collected through in-class observations, students' written …

Self-Reported Mastery: Moving On From Self-Reported Gains In Assessing Learning Outcomes, Michael S. Thompson

Theses and Dissertations

As the learning outcomes movement gains strength, the need to effectively measure learning outcomes becomes more important. This study looked at the effectiveness of self-reported mastery in measuring learning outcomes by examining the correlations between (a) self-reported mastery, (b) self-reported gains, and (c) objective measures of learning outcomes. The objective measures of learning outcomes were final exams for two classes, Calculus (consisting of two forms) and Statistics. The self-reported mastery and self-reported gains items were taken from the pilot student ratings form and the old student ratings form. A total of 848 undergraduate students completed the final exam and the …
