Development Of Unsaturated Flow Functions For Low Impact Development Stormwater Management Systems Filter Media And Flow Routines For Hydrological Modeling Of Permeable Pavement Systems, Iulia Aurelia Barbu

Doctoral Dissertations

Low Impact Development - Stormwater Management (LID-SWM) systems are relatively new technologies that were developed in order to meet the water quality criteria imposed by the Clean Water Act. LID-SWM is also used to replicate the natural hydrology of developed sites. However, the hydrological benefits of LID systems cannot be accurately predicted with the existing simulation models. Currently used software packages represent LID systems as storage units and do not specifically represent water routing through the systems' hydraulically restrictive sublayers. Since the LID's functionality at system level is not fully understood, the relationships of design variables and the systems' hydrological …

Evaluation And Optimization Of Bioretention Design For Nitrogen And Phosphorus Removal, Robin M. Stone

Master's Theses and Capstones

Laboratory and field investigations were conducted into the performance of modified bioretention system designs to reduce nutrient loads from stormwater runoff. Bioretention design characteristics of particular interest were filter media composition and structural configuration. A filter media admixture of raw aluminum-based water treatment residuals (WTR) in bioretention soil mix effectively adsorbed orthophosphate in laboratory tests (90-99% median removal efficiencies). WTR dewatered to 33% solids demonstrated consistently higher removal efficiencies (>99%). A bioretention system constructed in Durham, NH in 2011 includes a bioretention soil mix with raw WTR admixture (9% solids) and a structural design modeled after the UNHSC subsurface …

Muskeget Channel Tidal Energy Test Facility, Toby Dewhurst

Master's Theses and Capstones

Conceptual designs were investigated for a tidal hydrokinetic device test facility at Muskeget Channel, MA. Six platform concepts were investigated for devices of various sizes: A floating platform, a submerged buoyant platform, a fixed bottom-mounted gravity foundation, a telescoping bottom-mounted gravity foundation, a fixed four-pile group foundation, and a two-pile surface-piercing structure that could raise and lower a device. A natural berth option was also considered. Designs for each concept were developed for structural soundness, dynamic response, vibration, scour, corrosion, bio-fouling, electrical connection, monitoring, operating limits, ease of turbine installation and access, and cost. The floating platform and two-pile platform …

Minority Women In Stem: A Valuable Resource In The Global Economy, Ezella Mcpherson, Diane R. Fuselier-Thompson

Journal of the International Association for the Study of the Global Achievement Gap (Archived)

While there is an expected demographic shift of the ethnic minority population in the United States to become the majority population by 2020, few minority women successfully attain baccalaureate degrees in science, technology, engineering, and mathematical (STEM) fields. To address this gap, this article employs critical race feminism and narrative analysis methods to examine minority women’s challenges while pursuing undergraduate STEM degrees. Findings suggest that limited access to the field, isolation and alienation, and affordability create barriers that result in many minority women leaving STEM majors. Implications for practice include targeted institutional efforts to increase recruitment and retention efforts towards …

Academic And Social Barriers To Black And Latino Male Collegians' Success In Engineering And Related Stem Fields, Terrell Lamont Strayhorn, Leroy L. Long Iii, Joseph Allen Kitchen, Michael Steven Williams, Meg E. Stenz

Publications

Historically underrepresented racial/ethnic minorities (i.e. African Americans, Latinos, and Native Americans) have experienced barriers to their success in engineering and related STEM fields. These student populations have had lower degree attainment rates, switch to non-STEM majors more frequently, and experience unique social challenges when compared to White and Asian Pacific Islander counterparts. To examine these findings, nearly 50 interviews were conducted and analyzed in the present study to better understand the academic and social experiences of African American and Latino American men in these fields. Interviews revealed that these students tend to (1) feel alone and invisible, (2) lack same …

2012 Fall Engr333 Project Final Report, 2012 Fall Engr333

Control Scheme For Cathode Airflow During Load Swings In A Solid Oxide Fuel Cell/Gas Turbine System, Megan Rae Gorrell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Control and management of cathode airflow in a solid oxide fuel cell gas turbine hybrid power system was analyzed using the Hybrid Performance (HyPer) hardware simulation at the National Energy Technology Laboratory (NETL), U.S. Department of Energy. This work delves into previously unexplored operating practices for HyPer, via simultaneous manipulation of bypass valves and the electric load on the generator. The work is preparatory to the development of a Multi-Input, Multi-Output (MIMO) controller for HyPer. A factorial design of experiments was conducted to acquire data for 81 different combinations of the manipulated variables, which consisted of three air flow control …

A Model For Professional Development To Promote Engineering Design As An Integrative Pedagogy Within Stem Education, Joel D. Donna

Journal of Pre-College Engineering Education Research (J-PEER)

Engineering design activities can help educators to apply concepts and processes from within and across STEM domains. To facilitate these connections, there is a need for sustained, job-embedded, and collegial professional development that brings together teachers from across STEM domains to engage in design-based activities. These activities can help teachers better understand engineering design processes and can foster collaborations. This can lead to a culture shift within the school by which integration of STEM concepts and process becomes more seamless for both educators and their students. This paper describes a research-based model for professional development to promote engineering pedagogy to …

The Tower Builders: A Consideration Of Stem, Stse And Ethics In Science Education, Astrid Steele, Christine R. Brew, Brenda R. Beatty

Australian Journal of Teacher Education

The call for the integration of ethical considerations in the teaching of science is now firmly on the agenda. Taking as illustrative a science lesson in a pre-service teacher class, the authors consider the roles of STSE (science, technology, society and environment) and the increasingly influential heavily funded STEM (science, technology, engineering and mathematics) education initiatives. The origins and foci of both initiatives are discussed, as are their disparate ontological foundations. The use of Habermas’ knowledge theories in conjunction with ethical frameworks is posited as a way of considering both STSE and STEM perspectives and their implications for strengthening science …

Engineering Project Appraisal (2nd. Ed), Martin G. Rogers, Aidan Duffy

Books/Book Chapters

In most cases of civil engineering development, a range of alternative schemes meeting project goals are feasible, so some form of evaluation must be carried out to select the most appropriate to take forward. Evaluation criteria usually include the economic, environmental and social contexts of a project as well as the engineering challenges, so engineers must be familiar with the processes and tools used.

The second edition of Engineering Project Appraisal equips students with the understanding and analytical tools to carry out effective appraisals of alternative development schemes, using both economic and non-economic criteria. The building blocks of economic appraisal …

Incorporating Engineering Design Challenges Into Stem Courses, Dan L. Householder, Christine E. Hailey

Engineering Education Faculty Publications

Successful strategies for incorporating engineering design challenges into science, technology, engineering, and mathematics (STEM) courses in American high schools are presented in this paper. The developers have taken the position that engineering design experiences should be an important component of the high school education of all American youth. In most instances, these experiences in engineering design are infused into instruction programs in standards-based courses in science, technology, or mathematics. Sometimes the courses are designated as engineering courses and the engineering design component is emphasized. A growing number of researchers seek to understand whether the development of engineering habits of thought …

Surveying First-Year Students Prior Conceptual Understanding Of Direct Current Resistive Electric Circuits: An Update, Aidan O'Dwyer

Conference papers

There is an increasing diversity of educational background of students entering Level 7 and Level 8 programmes in engineering in Irish third level education. Student reasoning about basic electricity concepts often differs from accepted explanations. The paper reports, analyses and reflects on the results of a multiple-choice diagnostic test to assess student understanding of such concepts (developed by Engelhardt and Beichner (2004) for U.S. high school and college students) taken by four cohorts of students, on the same DIT Level 7 engineering programme, from 2008-12 (n=106) and two cohorts of students, on the same DIT Level 8 engineering programme, from …
