Assessing The Return On Investment For Various Types Of Break-In Training, Kim L. Trenbath

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis presents a Return on Investment, or ROI, model for various types of break-in training by utilizing employee learning curves as a factor of the cost. The model captures the additional profit earned when a company makes an investment in break-in training, training employees receive at the beginning of their employment. Research involves developing employee learning curves for break-in training vs. traditional training through experimentation. The thesis utilizes the improvement in the learning curve as the driving factor behind the profits. The ROI model is a comparison between the profits, or benefits minus cost, of a traditional and break-in …

Chemical And Physical Properties Of Acid Mine Drainage Floc, Catherine M. Bohan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage is a serious environmental concern in many regions worldwide, but especially in coal and metal mining regions. These acid drainages are often treated with chemicals to raise the pH of the water and to cause neutralization and precipitation of metals. As neutralization occurs, a looser gelatinous material called "floc" is produced. The effects of neutralizing chemical, pH, sulfate to iron molar ratio, and solids concentration on floc settling properties were determined in synthetic acid mine drainage. Sulfate was the important factor affecting floc physicochemical properties, increasing settling times from 25-125% and decreasing settling rates from 24-63%. Neutralization …

Improving The Conceptual Understanding Of Kinematics Through Graphical Analysis, Glenn W. Ellis, Warren A. Turner

Engineering: Faculty Publications

In this study, we use graphical analysis to develop a learner-centered approach to understanding kinematics. The learner-centered approach offers three advantages: it is consistent with pedagogy that has been shown to be effective for learning, it can be naturally integrated with real-time data collection using motion detectors or video analysis, and it provides a mechanism for developing insight into both physics and calculus. Students discover fundamental principles through a series of laboratory modules. The learning process is integrated into a conceptual framework through a variety of activities and application projects.

Lunar Lava Tube Radiation Safety Analysis, Giovanni De Angelis, J. W. Wilson, M. S. Clowdsley, J. E. Nealy, D. H. Humes, J. M. Clem

Mathematics & Statistics Faculty Publications

For many years it has been suggested that lava tubes on the Moon could provide an ideal location for a manned lunar base, by providing shelter from various natural hazards, such as cosmic radiation, meteorites, micrometeoroids, and impact crater ejecta, and also providing a natural environmental control, with a nearly constant temperature, unlike that of the lunar surface showing extreme variation in its diurnal cycle. An analysis of radiation safety issues on lunar lava tubes has been performed by considering radiation from galactic cosmic rays (GCR) and Solar Particle Events (SPE) interacting with the lunar surface, modeled as a regolith …

Design And Simulation Of Novel Arrayed Waveguide Grating By Using The Method Of Irregularly Sampled Zero-Crossings , Sai Hu

Department of Electrical and Computer Engineering Technical Reports

Arrayed waveguide grating (AWG) is playing an increasingly important role in dense wavelength division multiplexing (DWDM) system. The regular AWG device consists of an arrayed waveguide region where all the individual waveguides are equally spaced on the Rowland circle and the adjacent ones have constant length difference. The regularity of their positions and lengths leads to the phenomenon that a portion of the Rowland circle is occupied by the adjacent (undesired) order focused beams of the operation wavelength channels. The repetitions of the same wavelengths at different locations affect the device potential capacity. The method of irregularly sampled zero-crossings is …

The Evolution And Implications Of The Concentration Profiles Of An Analyte In Porous Adsorbent Particles Packed In A Capillary Electrochromatography Column Operated In The Analytical Mode, B. A. Grimes, Athanasios I. Liapis

Chemical and Biochemical Engineering Faculty Research & Creative Works

In this work, a mathematical model is constructed and solved to describe the propagation and dispersion of the mass wave of an analyte in a capillary electrochromatography (CEC) column packed with porous adsorbent particles and operated in the analytical mode. The evolution and dynamic behavior of the isoconcentration contours of the concentration of the analyte in the pores of the particles are presented in order to demonstrate the significant impact that the velocity of the intraparticle electroosmotic flow (EOF) encountered in CEC systems could have in reducing the overall intraparticle mass transfer resistance. It is shown that under both unretained …

Ccr4-Bearing T Cells Participate In Autoimmune Diabetes., Soon H. Kim, Mary M. Cleary, Howard S. Fox, Icos Coporation, Nora Sarvetnick

Journal Articles: Regenerative Medicine

Chemokine receptor expression is exquisitely regulated on T cell subsets during the course of their migration to inflammatory sites. In the present study we demonstrate that CCR4 expression marks a pathogenic population of autoimmune T cells. CCR4 was found exclusively on memory CD4(+) T cells during the progression of disease in NOD mice. Cells expressing the CCR4 ligand TARC (thymus- and activation-regulated chemokine) were detected within infiltrated islets from prediabetic mice. Interestingly, neutralization of macrophage-derived chemokine (MDC) with Ab caused a significant reduction of CCR4-positive T cells within the pancreatic infiltrates and inhibited the development of insulitis and diabetes. Furthermore, …

A Performance Study Of Lam And Mpich On An Smp Cluster, Brian Patrick Kearns

Dissertations and Theses

Many universities and research laboratories have developed low cost clusters, built from Commodity-Off-The-Shelf (COTS) components and running mostly free software. Research has shown that these types of systems are well-equipped to handle many problems requiring parallel processing. The primary components of clusters are hardware, networking, and system software. An important system software consideration for clusters is the choice of the message passing library.

MPI (Message Passing Interface) has arguably become the most widely used message passing library on clusters and other parallel architectures, due in part to its existence as a standard. As a standard, MPI is open for anyone …

Ocean Zoning For The Gulf Of Maine: A Background Paper, Fara Courtney, Jack Wiggin

Applying Learner-Centered Pedagogy To An Engineering Circuit-Theory Class At Smith College, Susan E. Voss, Glenn Ellis

Engineering: Faculty Publications

This paper discusses examples of learner-centered activities that have been incorporated into a circuit-theory course at Smith College. The learner-centered activities are organized around the structures of community, knowledge, and assessment. Specific examples include the use and ongoing development of "Concept Tests," frequent assessment of the students and the course, a peer-editing process facilitated by using class time to edit lab reports, and discussions and readings related to the social context within which electrical engineering concepts reside. This course is part of a program-wide effort to integrate learner-centered pedagogy into the entire engineering science curriculum.

Masters Theses

The purpose of this research is to study deviant behavior among collegiate student athletes. This study involves institutions in the Midwest region of the United States, particularly the Mid-American Conference (MAC). This study took on a sociological approach by interviewing specialized athletic officials, and examining different levels of social control by the National Collegiate Athletic Association (NCAA), along with its interaction with the Mid-American Conference. Various variables that affect social control such as gender, race, and economic conditions were also examined to get an understanding of how these factors influence behavior.

Development Of A Simulation For The Prediction Of Pvdf Surface Velocity Sensor Response For Vibrating Beams And Rectangular Plates, Brian C. Zellers

Masters Theses

A simulation for the prediction of Polyvinylidene Flouride (or PVDF) sensor charge response to structural vibration displacements of beam and rectangular plate structures was developed. The simulation uses measured vibration displacements from an actual structure using point sensors (accelerometers) assembled in an array on the surface of the structure. The PVDF sensor charge output equation was written for a PVDF film of constant spatial sensitivity so that numerical analysis tools in Matlab® can be used to solve the equation. Preliminary experimental results showed that the bending strain component, due to transverse vibration displacements, is the dominant term for both the …

Training Fuzzy Systems With The Extended Kalman Filter, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

The generation of membership functions for fuzzy systems is a challenging problem. We show that for Mamdani-type fuzzy systems with correlation-product inference, centroid defuzzification, and triangular membership functions, optimizing the membership functions can be viewed as an identification problem for a nonlinear dynamic system. This identification problem can be solved with an extended Kalman filter. We describe the algorithm and compare it with gradient descent and with adaptive neuro-fuzzy inference system (ANFIS) based optimization of fuzzy membership functions. The methods discussed in this paper are illustrated on a fuzzy filter for motor winding current estimation, and are compared with Butterworth …
