Wind Power West Michigan - Project Overview, Erik Edward Nordman

Technical Reports

Wind energy has the potential to be an environmentally sensitive alternative to fossil fuels because wind is renewable and can be used to generate electricity without emitting greenhouse gases and other pollutants. Michigan’s coastal zones possess abundant wind resources. However, wind energy development might present challenges for tourism-dependent lakeshore communities. Poorly sited wind farms may interfere with other uses of the coast, such as recreation, commercial fishing, and nature preservation, and not all communities are prepared to manage these conflicts.

Theory Of Planned Behavior Model Fit Using Atod Prevention Program Data, Ying Jin

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report is to test the Theory of Planned Behavior (TpB) model fit using the data collected from the ATOD Prevention Program conducted by the Operation Snowball Program from year 2004 to 2007 in Naperville, Illinois. Measurement Model and Structural Equation Modeling are used as principal modeling methods to test internal consistency of assigned measures for each construct and the dependency between constructs respectively. The results show that the ATOD Prevention Program data does not fit the TpB model perfectly. Extra paths should be added to the original theoretical model in order to obtain a satisfactory model fit.

Surface Mucous As A Source Of Genomic Dna From Atlantic Billfishes (Istiophoridae) And Swordfish (Xiphiidae), John P. Hoolihan, Nerida G. Wilson, Ronald M. Faugue, Andrea Bernard, Rebekah L. Horn, Derke Snodgrass, Duane R. Schultz

Marine & Environmental Sciences Faculty Articles

Procedures for sampling genomic DNA from live billfishes involve manual restraint and tissue excision that can be difficult to carry out and may produce stresses that affect fish survival. We examined the collection of surface mucous as a less invasive alternative method for sourcing genomic DNA by comparing it to autologous muscle tissue samples from Atlantic blue marlin (Makaira nigricans), white marlin (Tetrapturus albidus), sailfish (Istiophorus platypterus), and swordfish (Xiphias gladius). Purified DNA from mucous was comparable to muscle and was suitable for conventional polymerase chain reaction, random amplified polymorphic DNA analysis, …

The Effects Of Chronic Mercuric Chloride Ingestion In Female Sprague–Dawley Rats On Fertility And Reproduction, J.C. Heath, Y. Abdelmageed, T.D. Braden, A.C. Nichols, D.A. Steffy

Research, Publications & Creative Work

Thirty-days-old female rats were chronically exposed, for 60 days, to 1or 2 mg/kg/day of mercuric chloride or an equivalent volume of water, via gavage. At 90 days of age they were mated with unexposed males. At approximately day 13 of gestation necropsies were performed on the females. Data were collected on the number of implantations and non-viable implantations in the uterus. No physical signs of Hg intoxication were seen except in weight gain. There were significantly fewer implantations in the high HgCl2 group, with significantly more non-viable implantations in the low and high HgCl2 groups, compared to controls. Lower levels …

Validation Of The Principal’S Computer Technology Survey, Lantry Brockmeier, Nicole Gibson

Georgia Educational Researcher

The purpose of this study was to provide a more in-depth analysis of the psychometric characteristics of the Principal’s Computer Technology Survey (PCTS). The PCTS developmental process yielded a 40–item survey with groups of items comprising five subscales (i.e., curriculum integration, perceptions, acquired expertise, needs assessment, and professional development). Principals’ responses to items within the five subscales was measured on a five-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). An expert panel reviewed the instrument plus exploratory factor analyses and confirmatory factor analyses were conducted. This analysis resulted in a restructured instrument …

Toward A Coherent Test For Disparate Impact Discrimination, Jennifer L. Peresie

Indiana Law Journal

Statistics are generally plaintiffs' primary evidence in establishing a prima facie case of disparate impact discrimination. Thus, the use, or misuse, of statistics dictates case outcomes. Lacking a coherent test for disparate impact, courts choose between the two prevailing tests, statistical significance and the four-fifths rule, in deciding cases, and these tests frequently produce opposite results. Litigants thus face considerable uncertainty and the risk that a judge's preferred outcome will dictate which test is applied. This Article recognizes that the two tests perform complementary functions that both play a useful role in determining whether liability should be imposed. statistical significance …

Pointed Trees Of Projective Spaces, Linda Chen, A. Gibney, D. Krashen

Mathematics & Statistics Faculty Works

We introduce a smooth projective variety T(d,n) which compactifies the space of configurations of it distinct points oil affine d-space modulo translation and homothety. The points in the boundary correspond to n-pointed stable rooted trees of d-dimensional projective spaces, which for d = 1, are (n + 1)-pointed stable rational curves. In particular, T(1,n) is isomorphic to ($) over bar (0,n+1), the moduli space of such curves. The variety T(d,n) shares many properties with (M) over bar (0,n+1). For example, as we prove, the boundary is a smooth normal crossings divisor whose components are products of T(d,i) for i < n and it has an inductive construction analogous to but differing from Keel's for (0,n+1). This call be used to describe its Chow groups and Chow motive generalizing [Trans. Airier. Math. Soc. 330 (1992), 545-574]. It also allows us to compute its Poincare polynomials, giving all alternative to the description implicit in [Progr. Math., vol. 129, Birkhauser, 1995, pp. 401-417]. We give a presentation of the Chow rings of T(d,n), exhibit explicit dual bases for the dimension I and codimension 1 cycles. The variety T(d,n) is embedded in the Fulton-MacPherson spaces X[n] for any smooth variety X, and we use this connection in a number of ways. In particular we give a family of ample divisors on T(d,n) and an inductive presentation of the Chow motive of X[n]. This also gives an inductive presentation of the Chow groups of X[n] analogous to Keel's presentation for (M) over bar (0,n+1), solving a problem posed by Fulton and MacPherson.

Light-Particle Single Ionization Of Argon: Influence Of The Projectile Charge Sign, Sebastian Otranto, Ronald E. Olson

Physics Faculty Research & Creative Works

The ionization of the 3p orbital of argon by incident electrons and positrons is studied by means of the post version of the continuum distorted wave-eikonal initial-state model. Results are presented at both 200 and 500 eV impact energies for conditions amenable to present experiments. Differences in the fully differential cross sections (FDCSs) are analyzed and the influence of the projectile charge sign on the emission dynamics is discussed. The FDCSs are found to display the classic binary plus recoil peak structure at 500 eV, but transition to a more complicated four-lobed structure at the lower impact energy.

Thermal Expansion And Grüneisen Parameter In Quantum Griffiths Phases, Thomas Vojta

Physics Faculty Research & Creative Works

We consider the behavior of the Grüneisen parameter, the ratio between thermal expansion and specific heat, at pressure-tuned infinite-randomness quantum-critical points and in the associated quantum Griffiths phases. We find that the Grüneisen parameter diverges as ln (T₀ /T) with vanishing temperature T in the quantum Griffiths phases. at the infinite-randomness critical point itself, the Grüneisen parameter behaves as [ln (T₀ /T)]^{1+1/ (νψ)} where ν and ψ are the correlation length and tunneling exponents. Analogous results hold for the magnetocaloric effect at magnetic-field-tuned transitions. We contrast clean and dirty systems, we discuss subtle differences between Ising and …

Quantitative Rescattering Theory For High-Order Harmonic Generation From Molecules, Anh-Thu Le, R. R. Lucchese, S. Tonzani, Toru Morishita, C. D. Lin

Physics Faculty Research & Creative Works

The quantitative rescattering theory (QRS) for high-order harmonic generation (HHG) by intense laser pulses is presented. According to the QRS, HHG spectra can be expressed as a product of a returning electron wave packet and the photorecombination differential cross section of the laser-free continuum electron back to the initial bound state. We show that the shape of the returning electron wave packet is determined mostly by the laser. The returning electron wave packets can be obtained from the strong-field approximation or from the solution of the time-dependent Schrödinger equation (TDSE) for a reference atom. The validity of the QRS is …

Simulations Of Baryon Acoustic Oscillations. Ii. Covariance Matrix Of The Matter Power Spectrum, Ryuichi Takahashi, Naoki Yoshida, Masahiro Takada, Takahiko Matsubara, Naoshi Sugiyama, Issha Kayo, Atsushi J. Nishizawa, Takahiro Nishimichi, Shun Saito, Atsushi Taruya

Physics Faculty Research & Creative Works

We use 5000 cosmological N-body simulations of 1 h^-3 Gpc³ box for the concordance ËCDM model in order to study the sampling variances of a nonlinear matter power spectrum. We show that the non-Gaussian errors can be important even on large length scales relevant for baryon acoustic oscillations (BAOs). Our findings are the following: (1) the non-Gaussian errors degrade the cumulative signal-to-noise ratios (S/Ns) for the power spectrum amplitude by up to a factor of 2 and 4 for redshifts z = 1 and 0, respectively; (2) there is little information on the power spectrum amplitudes in the …

Stacked Search For Gravitational Waves From The 2006 Sgr 1900+14 Storm, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with the 2006 March 29 SGR 1900+14 storm. A new search method is used, "stacking" the GW data around the times of individual soft-gamma bursts in the storm to enhance sensitivity for models in which multiple bursts are accompanied by GW emission. We assume that variation in the time difference between burst electromagnetic emission and potential burst GW emission is small relative to the GW signal duration, and we time-align GW excess power time-frequency tilings containing individual burst triggers to their corresponding electromagnetic emissions. We use …

Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero

Department of Environmental Studies: Undergraduate Student Theses

Hydroxyapatite is a mineral that is very inexpensive, easily made, and binds well to lead. In this procedure its application will be paired with Flame Atomic Absorption Spectroscopy (Flame AA) to detect lead concentrations in water to ppb levels. While ppb concentrations of lead are too dilute to produce a response from the Flame AA by using Hydroxyapatite to concentrate lead molecules from a larger volume and dissolving the Hydroxyapatite into a smaller volume it may be able to produce a response. The method could provide an inexpensive, efficient, and accurate way to detect lead concentrations to the ppb level …

Nebraska Wind Power: A Comparitive Study Of Knowledge And Attitudes, Cameron Helgren

Department of Environmental Studies: Undergraduate Student Theses

Abstract The goal of this project is to assess the knowledge and attitudes of Nebraskans on the issue of wind power. The point of this research is to learn whether the presence of wind power has a positive effect on a person’s knowledge about and attitudes toward wind power and wind turbines. Using mail surveys, qualitative and quantitative data were collected from the towns of Pierce and Ainsworth Nebraska. The surveys aided in seeing patterns of knowledge about wind power and wind turbines and positive and negative attitudes and major concerns regarding wind power.

Spectroscopic Investigations On Polypropylene-Carbon Nanofiber Composites: I. Raman And Electron Spin Resonance Spectroscopy, Mircea Chipara, John R. Villarreal, Magdalena Dorina Chipara, Karen Lozano, Alin Cristian Chipara, David J. Sellmyer

David Sellmyer Publications

Isotactic polypropylene-vapor grown carbon nanofiber composites containing various fractions of carbon nanofibers, ranging from 0 to 20 wt %, have been prepared. Raman spectroscopy was used to analyze the effect of the dispersion of carbon nanofibers within polypropylene and the interactions between carbon nanofibers and macromolecular chains. The as-recorded Raman spectra have been successfully fitted by a linear convolution of Lorentzian lines. Changes of the Raman lines parameters (position, intensity, width, and area) of polypropylene and carbon nanofibers were analyzed in detail. The Raman spectra of the polymeric matrix—at low concentrations of nanofibers—show important modifications that indicate strong interactions between …

A Near-Infrared Spectroscopic Survey Of Cool White Dwarfs In The Sloan Digital Sky Survey, Mukremin Kilic, Piotr M. Kowalski, Ted Von Hippel

Publications

We present near-infrared photometric observations of 15 and spectroscopic observations of 38 cool white dwarfs (WDs). This is the largest near-infrared spectroscopic survey of cool WDs to date. Combining the Sloan Digital Sky Survey photometry and our near-infrared data, we perform a detailed model atmosphere analysis. The spectral energy distributions of our objects are explained fairly well by model atmospheres with temperatures ranging from 6300 K down to 4200 K. Two WDs show significant absorption in the infrared, and are best explained with mixed H/He atmosphere models. Based on the up-to-date model atmosphere calculations by Kowalski & Saumon, we find …

Temporal Geophysical Signatures From Contaminant-Mass Remediation, Vukenkeng Che-Alota, Estella A. Atekwana, Eliot A. Atekwana, William August Sauck, D. Dale Werkema

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

We have previously documented changes in bulk electrical conductivity, self-potential (SP), and ground-penetrating-radar (GPR) reflections in a field setting caused by biogeochemical transformations of hydrocarbon-contaminated media. These transformations are associated with hydrocarbon biodegradation. The results of surface geophysical surveys acquired in 1996, 2003, and 2007 document changes in geophysical signatures associated with removing hydrocarbon mass in the contaminated zone. Initial investigations in 1996 showed that relative to background, the contaminated area was characterized by higher bulk electrical conductivity, positive SP anomaly, and attenuated GPR reflections. Repeated surveys in 2003 and 2007 over the contaminated area showed that in 2007, the …

A Semilinear Wave Equation With Smooth Data And No Resonance Having No Continuous Solution, Jose F. Caicedo, Alfonso Castro

All HMC Faculty Publications and Research

We prove that a boundary value problem for a semilinear wave equation with smooth nonlinearity, smooth forcing, and no resonance cannot have continuous solutions. Our proof shows that this is due to the non-monotonicity of the nonlinearity.

Evolution Versus Revolution As A Strategy For Thin Client Acceptance: Case Study, Paul Doyle, Mark Deegan, Ciaran O'Driscoll

Conference papers

Thin Clients have evolved from simple text based CRT dumb terminal devices in the 1960s, into a sophisticated architecture encompassing hardware, software, networks and protocols. However despite this recent evolution the Thin Client model has yet to re-emerge as a relevant design in an IT industry where Fat Clients (desktops and laptops) thrive. This paper describes two case studies performed within the Technological University Dublin School of Computing, focused on the issue of student acceptance of this technology. The first case study provides a dedicated single service Thin Client implementation, while the second case study adopts a process of coexistence …

Tableau Algorithm For Concept Satisfiability In Description Logic Alch, Satya S. Sahoo, Krishnaprasad Thirunarayan

Kno.e.sis Publications

The provenir ontology is an upper-level ontology to facilitate interoperability of provenance information in scientific applications. The description logic (DL) expressivity of provenir ontology is ALCH, that is, it models role hierarchies (H) (without transitive roles and inverse roles). Even though the complexity results for concept satisfiability for numerous variants of DL such as ALC with transitively closed roles (ALC_R+ also called S), inverse roles SI, and role hierarchy SHI have been well-established, similar results for ALCH has been surprisingly missing from the literature. Here, we show that the complexity of the concept satisfiability problem for the ALCH variant …

“Best K”: Critical Clustering Structures In Categorical Datasets, Keke Chen, Ling Liu

Kno.e.sis Publications

The demand on cluster analysis for categorical data continues to grow over the last decade. A well-known problem in categorical clustering is to determine the best K number of clusters. Although several categorical clustering algorithms have been developed, surprisingly, none has satisfactorily addressed the problem of best K for categorical clustering. Since categorical data does not have an inherent distance function as the similarity measure, traditional cluster validation techniques based on geometric shapes and density distributions are not appropriate for categorical data. In this paper, we study the entropy property between the clustering results of categorical data with different K …

City Of Gloucester Harbor Plan & Designated Port Area Master Plan, July 2009, Sarah Buck, Greg Ketchen, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

A harbor plan is a waterfront land and water use plan intended to establish the community’s objectives, standards, and policies for guiding public and private utilization of land and of water within and adjacent to the commonwealth’s jurisdiction. The 1999 Gloucester Harbor Plan was chiefly focused on infrastructure improvements for both maritime and visitor oriented industries along the waterfront as a central means of recharging the harbor’s economic engine. Many of the improvements have been completed in the wake of this plan. However, it largely ignored the confusing web of land use regulations that has since emerged as the central …
