2013 Fall Engr333 Project Final Report, 2013 Fall Engr333

ENGR 333

During the fall of 2013, the Engineering 333 class was asked the question, “what would it take for Calvin College to operate a biofuel vehicle from campus resources?” The three primary considerations included:

• Determining the optimal biofuel feedstock in terms of availability, transportation, and processing.
• Selecting a biofuel vehicle for conversion or purchase to operate on the selected feedstock.
• Designing the infrastructure and process required for operating the selected biofuel vehicle. The design and research described below proposes an environmentally sustainable and cost-effective method for integrating a biofuel vehicle into Calvin’s existing infrastructure.

Supernova Neutrino Nucleosynthesis Of Light Elements With Neutrino Oscillations, Takashi Yoshida, Toshitaka Kajino, Hidekazu Yokomakura, Keiichi Kimura, Akira Takamura, Dieter H. Hartmann

Publications

Light element synthesis in supernovae through neutrino-nucleus interactions, i.e., the ν-process, is affected by neutrino oscillations in the supernova environment. There is a resonance of 13-mixing in the O/C layer, which increases the rates of charged-current ν-process reactions in the outer He-rich layer. The yields of 7Li and 11B increase by about a factor of 1.9 and 1.3, respectively, for a normal mass hierarchy and an adiabatic 13-mixing resonance, compared to those without neutrino oscillations. In the case of an inverted mass hierarchy and a non-adiabatic 13-mixing resonance, the increase in the 7Li and 11B yields is much smaller. Observations …

Commentary On "Family Roots: Sustenance For Samoan And Tongan American Elders", Meripa T. Godinet

Journal of Family Strengths

The article discusses the relevance of family as the foundation of well being for Samoan and Tongan elders. Negotiating dual identities (Samoan American or Tongan American) can be challenging, particularly when contexts of each identity are at odds with one another. This study indicated relevant findings that underscored the role and responsibility of Samoan and Tongan elders in transmitting cultural ways of knowing and doing to current and future generations. The role of families then becomes all the more important as they are key to supporting the health and wellbeing of their elders.

Liquid Core Waveguide Sensors With Single And Multi-Spot Excitation, Lynnell Uilani Wai Yee Zempoaltecatl

Theses and Dissertations

Using silicon based microfabrication and materials, a photonic platform, capable of single bioparticle analysis, has been developed. This platform combines liquid and hollow core waveguides on the micron-scale (5 µm x 12 µm) to isolate femtoliter sized sample volumes. Fluorescence excitation and signals in the visible range are directed into and out of the sample volume at an orthogonal angle to maximize signal-to-noise. In order to guide light in a low-index material antiresonant reflecting optical waveguides (ARROWs) were incorporated into the platform. This thesis reveals the development path of these structures over several device generations including innovations in material, geometries, …

Direct Coupling Of Photonic Modes And Surface Plasmon Polaritons Observed In 2-Photon Peem, Robert Campbell Word, Joseph Fitzgerald, Rolf Könenkamp

Physics Faculty Publications and Presentations

We report the direct microscopic observation of optical energy transfer from guided photonic modes in an indium tin oxide (ITO) thin film to surface plasmon polaritons (SPP) at the surfaces of a single crystalline gold platelet. The photonic and SPP modes appear as an interference pattern in the photoelectron emission yield across the surface of the specimen. We explore the momentum match between the photonic and SPP modes in terms of simple waveguide theory and the three-layer slab model for bound SPP modes of thin metal films. We show that because the gold is thin (30- 40 nm), two SPP …

Rapid Generation Of Light Beams Carrying Orbital Angular Momentum, Mohammad Mirhosseini, Omar S. Magaña-Loaiza, Changchen Chen, Brandon Rodenburg, Mehul Malik, Robert W. Boyd

Faculty Publications

We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerre-Gaussian and vortex orbital-angular-momentum (OAM) modes, along with modes in a set that is mutually unbiased with respect to the OAM basis. Additionally, we have demonstrated rapid switching among the generated modes at a speed of 4 kHz, which is much faster than the speed regularly achieved by phase-only spatial light modulators (SLMs). The dynamic control of both phase and amplitude of a laser beam is an enabling technology for classical communication and …

Reduced Row Echelon Form And Non-Linear Approximation For Subspace Segmentation And High-Dimensional Data Clustering, Akram Aldroubi, Ali Sekmen

Computer Science Faculty Research

Given a set of data W={w1,…,wN}∈RD drawn from a union of subspaces, we focus on determining a nonlinear model of the form U=⋃i∈ISi, where {Si⊂RD}i∈I is a set of subspaces, that is nearest to W. The model is then used to classify W into clusters. Our approach is based on the binary reduced row echelon form of data matrix, combined with an iterative scheme based on a non-linear approximation method. We prove that, in absence of noise, our approach can find the number of subspaces, their dimensions, and an orthonormal basis for each subspace Si. We provide a comprehensive analysis …

The Impact Of Small Pass-Through Wetlands And Stormwater Retention Ponds On Dissolved Organic Matter, Michael B. Burkett

Theses

Retention ponds and mitigation wetlands have become more common throughout the urban and suburban landscape for stormwater management and nutrient removal. It is well known that wetlands can effectively remove nitrogen and phosphorus, but the effect of wetlands on dissolved organic matter (DOM) and its impact on water quality is often overlooked, in spite of the importance of DOM in aquatic ecosystems. We seasonally sampled the inflow and outflow of five natural wetlands, five created wetlands and ten stormwater retention ponds in the urban and suburban environment of Monroe County, New York, for dissolved organic carbon (DOC), dissolved organic nitrogen …

Statistical analysis of experimental tensile and ultrasonic scanning data highlighted the sensitivity of weld strength and the presence of weld zone inclusions and interfacial defects to the process factors of upset current, flashing …

Couple Implicit Rules For Facilitating Disclosure And Relationship Quality With Romantic Relational Aggression As A Mediator, Karl Nathan Meng

Theses and Dissertations

This study examines the association between couple implicit rules related to facilitating disclosure and marital quality with husband and wife romantic relational aggression as potential mediators. Couples (N-353 couples) who participated in the Flourishing Families Project, reported on their use of couple implicit rules related to disclosure. Results indicated that implicit rules for couple disclosure were positively related to marital quality for both husbands and wives. Those couples who reported more use of implicit rules related to disclosure were also likely to use less romantic relational aggression. In turn, both husband and wife romantic relational aggression was negatively related to …

Weak Interaction Studies Ith 6He, A. Knecht, Z. T. Alexander, Y. Bagdasarova, T. M. Cope, B. G. Delbridge, X. Fléchard, A. García, R. Hong, E. Liénard, P. Mueller, O. Naviliat-Cuncic, A. S.C. Palmer, R. G.H. Robertson, D. W. Storm, H. E. Swanson, S. Utsuno, F. Wauters, William Williams, C. Wrede, D. W. Zumwalt

Physics: Faculty Publications

The 6He nucleus is an ideal candidate to study the weak interaction. To this end we have built a high-intensity source of 6He delivering ∼1010 atoms/s to experiments. Taking full advantage of that available intensity we have performed a high-precision measurement of the 6He half-life that directly probes the axial part of the nuclear Hamiltonian. Currently, we are preparing a measurement of the beta-neutrino angular correlation in 6He beta decay that will allow to search for new physics beyond the Standard Model in the form of tensor currents. © 2013 AIP Publishing LLC.

Student Works (2010-2019)

Salat is an Islamic prayer ritual that all Muslims must perform five times a day. The salatphysical manoeuvres steps include various motions such as standing, bowing, prostration, and sitting. Recently, the study of salat movements from the perspective of science has been widely investigated. The current study evaluated the impact of salatmovements on the biomechanical response of human muscle using electromyography (EMG). The eight upper-bodymuscles involved were the neck extensors (NE), sternocleidomastoideus (SCM), trapezius (TRP), deltoid (DL), bicepsbrachii (BB), triceps brachii (TB), rectus abdominus (RA), and erector spine (ES) and the four lower-body muscles involved were the rectus femoris (RF), …

Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng

Dartmouth Scholarship

Abstract Bruce and Young (1986) proposed a model for face processing that begins with structural encoding, followed by a split into two processing streams: one for the dynamic aspects of the face (e.g., facial expressions of emotion) and the other for the invariant aspects of the face (e.g., gender, identity). Yet how this is accomplished remains unclear. Here, we took a psychophysical approach using contrast negation to test the Bruce and Young model. Previous research suggests that contrast negation impairs processing of invariant features (e.g., gender) but not dynamic features (e.g., expression). In our first experiment, participants discriminated differences in …

When successfully managed, improved glycemic control occurs, as evidenced by reductions in glycosylated hemoglobin (A1C) levels. A review of the literature surrounding this topic and description of a capstone scholarly project utilizing findings from the literature to create an evidence-based telephone follow-up pilot study are included. Findings from this study did not reveal statistically significant reductions in A1C levels with …

Community Capital And Local Economic Development Efforts, Andrew A. Zekeri

Professional Agricultural Workers Journal

Actions by local groups and leaders constitute an essential but poorly understood element of many rural economic development efforts. Previous studies suggest that local development efforts can influence community changes, but questions remain about why localities differ in economic development efforts. Drawing upon community capital framework and human ecological theory, the purpose of this research was to examine the effects of community capital on economic development efforts in rural communities. Hierarchical regression results indicate that social capital, cultural capital, built capital significantly predict economic development effort to develop recreation and tourism and human services. Despite that, only built capital and …

The Fate Of Local Food Systems In The Global Industrialization Market: Food And Social Justice In The Rural South, Wylin D. Wilson, Reuben C. Warren, Stephen O. Sodeke, Norbert Wilson

Professional Agricultural Workers Journal

This paper investigates the connection between local food systems, health disparities, and social justice in the rural South. It begins with the relationship between food insecurity and health disparities that disproportionately affect racial and ethnic minority populations, and non-minority women and children. First, we discuss the concept of health disparities within the context of bioethics and public health ethics in order to explore the link between the food system and health as a social justice issue. Second, we define health disparities and discuss how they have historically plagued and disadvantaged racial minority populations. Third, we examine these disparities within the …

The Impact Of Selected Socioeconomic Factors On Asset Building In Rural Communities, Nii O. Tackie, Judith N. Aboagye, Gwendolyn J. Johnson, Millicent Braxton, Latanya Hunt-Haralson, Gertrude D. Wall

Professional Agricultural Workers Journal

The study examined the impact of selected socioeconomic factors on asset building. Using a questionnaire, data were obtained from a convenience sample of 204 participants from several Alabama Black Belt Counties, and analyzed using descriptive statistics and logit analysis. The results showed that a majority (64%) was willing to participate in an asset building program. Of this, an overwhelming majority (at most 70%) wanted to set up a small business; further their education, or purchase a home. In addition, one socioeconomic factor, age, had a statistically significant (p = 0.016) effect on willingness to participate in an asset building …

The Role Of Defects In Interlayer Cation Exchange In Clay Minerals, Laura Cardon, Dr. Barry R. Bickmore

Journal of Undergraduate Research

Clay minerals comprise a large portion of the abundant sediment that covers the earth’s surface. As such, they have a significant impact on society in regard to land development and also water and mineral resources. The purpose of this study was to help unravel the mysteries of clay mineral properties by focusing special attention on the effects of defects found in the clay mineral structure. These defects are believed to play a key role in the exchange of, oftentimes toxic, interlayer cations in the clay mineral. Better understanding of this exchange would lead to better water management and aid us …
