Singular Superposition/Boundary Element Method For Reconstruction Of Multi-Dimensional Heat Flux Distributions With Application To Film Cooling Holes, Mahmood Silieti, Eduardo Divo, Alain J. Kassab Jan 2009

Singular Superposition/Boundary Element Method For Reconstruction Of Multi-Dimensional Heat Flux Distributions With Application To Film Cooling Holes, Mahmood Silieti, Eduardo Divo, Alain J. Kassab

Publications

A hybrid singularity superposition/boundary element-based inverse problem method for the reconstruction of multi-dimensional heat flux distributions is developed. Cauchy conditions are imposed at exposed surfaces that are readily reached for measurements while convective boundary conditions are unknown at surfaces that are not amenable to measurements such as the walls of the cooling holes. The purpose of the inverse analysis is to determine the heat flux distribution along cooling hole surfaces. This is accomplished in an iterative process by distributing a set of singularities (sinks) inside the physical boundaries of the cooling hole (usually along cooling hole centerline) with a given …

Assuring Access: One Library's Journey From Print To Electronic Only Subscriptions, Aparna Zambare, Anne Marie Casey, John Fierst, David Ginsburg, Judith O'Dell, Timothy Peters

Publications

The migration of library collections from print to electronic formats has been a priority for many institutions during the last ten years and has played a key role in the transformation of the modern academic library. Not surprisingly, this process has been labor-intensive, costly, and occasionally frustrating to those involved in the transformation. This article recounts the challenges that the Central Michigan University Libraries faced and the measures it established to overcome these challenges as it undertook the process of successfully moving from a print-based to a predominately electronic only subscription collection.

Using Sunflower Plots And Classification Trees To Study Typeface Legibility, Edgar C. Merkle, Barbara S. Chaparro Jan 2009

Using Sunflower Plots And Classification Trees To Study Typeface Legibility, Edgar C. Merkle, Barbara S. Chaparro

Publications

This article describes the application of sunflower plots and classification trees to the study of onscreen typeface legibility. The two methods are useful for describing high-dimensional data in an intuitive manner, which is crucial for interacting with both the typographers who design the typefaces and the practitioners who must make decisions about which typeface to use for specific applications. Furthermore, classification trees help us make specific recommendations for how much of a character attribute is “enough” to make it legible. We present examples of sunflower plots and classification trees using data from a recent typeface legibility experiment, and we present …

Deception, Decisions, And Investor Education, Jayne W. Barnard Jan 2009

Deception, Decisions, And Investor Education, Jayne W. Barnard

Faculty Publications

Tens of millions of dollars each year are spent on investor education. Because older adults (those aged sixty and older) are disproportionately victims of investment fraud schemes, many educational programs are targeted at them. In this Article, Professor Barnard questions the effectiveness of these programs. Drawing on recent studies from marketing scholars, neurobiologists, social psychologists, and behavioral economists examining the ways in which older adults process information and make decisions, she offers a model of fraud victimization (the "deception/decision cycle") that explains why older adults are often vulnerable to investment fraud schemes. She then suggests that many of the factors …

How Planned Parenthood V. Casey (Pretty Much) Settled The Abortion Wars, Neal Devins Jan 2009

How Planned Parenthood V. Casey (Pretty Much) Settled The Abortion Wars, Neal Devins

Faculty Publications

More than twenty-one years after Robert Bork's failed Supreme Court nomination and seventeen years after Planned Parenthood of Southeastern Pennsylvania v. Casey, the rhetoric of abortion politics remains unchanged. Pro-choice interests, for example, argue that states are poised to outlaw abortion and that Roe v. Wade is vulnerable to overruling. In this Essay, I will debunk those claims. First, I will explain how Casey's approval of limited abortion rights reflected an emerging national consensus in 1992. Second, I will explain why the Supreme Court is unlikely to risk political backlash by formally modifying Casey- either by restoring the trimester test …

The distributed nature of the environment in which privacy and security policies operate requires tools that help enforce consistency of policy rules across different domains. Furthermore, because changes to policy rules are required as policies evolve over time, such tools can be used by policy administrators to ensure the consistency of policy changes. in this paper, we describe a number of different policy analysis tools and techniques that we have developed over the years and present them in a unified framework in which both privacy and security policies are discussed. We cover dominance analyses of general policies, conflicts among authorizations …

Processing And Storage Effects On The Polyphenolic Content And Antioxidant Capacity Of Conventional And Sugar-Free Blueberry Jams, Chelsea Castrodale, Luke Howard, Cindi Brownmiller Jan 2009

Processing And Storage Effects On The Polyphenolic Content And Antioxidant Capacity Of Conventional And Sugar-Free Blueberry Jams, Chelsea Castrodale, Luke Howard, Cindi Brownmiller

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Fresh blueberries have received much attention due to their positive role in human health and disease prevention. The abundance of polyphenolics, namely anthocyanins and procyanidins, is thought to play an important role in health promotion. Due to seasonal availability and limited shelf-life, blueberries are commonly preserved and consumed in various thermally processed forms (jams, juices, canned whole fruit, and purées). Both conventional high sugar and sugar-free blueberry jams are available on the market, but no information is available on how different formulations, processing conditions, and storage of processed jams affect the retention of polyphenolics and antioxidant capacity found in fresh …

Application Of Cross-Linked Rice Starches As Drug Delivery Matrices In Monolithic Tablets, Christopher F. Peluso, Fernanda O. Onofre, Ya-Jane Wang

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The sustained release properties of regular and waxy rice starches and their derivatives were studied in tablets. The starches were cross-linked to different levels with epichlorohydrin, and the sustained release properties, swelling power, and rheological characteristics of the matrices prepared were determined. Propranolol hydrochloride was used as a model drug. The sustained release properties of waxy rice starch improved with increasing cross-linking levels, whereas cross-linking had little impact on the functionality of regular rice starch matrices. There was an increase in swelling power for both regular and waxy rice starches as cross-linking levels increased. Both starches showed an increase in …

Correlation Of Calcium And Magnesium Intakes To Frequency Of Muscle Cramps In Female College Athletes, Jennifer Schneider, Marjorie Fitch-Hilgenberg

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Muscle cramps are involuntary, painful, sudden contractions of skeletal muscles that can cause detrimental effects on athletic performance. Recent data suggest that low intakes of dietary calcium (Ca) and magnesium (Mg) can enhance or cause muscle cramps. The purpose of this study was to determine the correlation between Ca and Mg intakes and muscle cramping in female college athletes. Athletes completed a 24-hour dietary recall and a survey on frequency and location of muscle cramps. Of those surveyed, 8 participated in basketball, 21 in softball, and 10 in gymnastics. Calcium and Mg intakes were calculated from dietary recall data using …

Establishing A Rapid And Effective Method For Screening Salt Tolerance In Soybean, Mioko Tamura, Pengyin Chen Jan 2009

Establishing A Rapid And Effective Method For Screening Salt Tolerance In Soybean, Mioko Tamura, Pengyin Chen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Chlorine (Cl) toxicity has been recognized as a constraint for soybean production. Although the use of a Cl-tolerant crop easily solves the problem, current screening methodologies for Cl tolerance are often ineffective because of inadequate means of detecting and measuring plant response to salinity. In order to facilitate the evaluation process and selection of Cl-tolerant genotypes, a study was conducted to develop a rapid and effective method for screening Cl tolerance in soybean. Seeds of five soybean cultivars, each representing either the includer or excluder genotype to salt stress, were grown in a greenhouse in two different growing media (potting …
