Assessing The Relationship Between Organizational Management Factors And A Resilient Safety Culture In A Collegiate Aviation Program With Safety Management Systems (Sms), Daniel Kwasi Adjekum, Marcos Fernandez Tous

Aviation Faculty Publications

Extant research advocates for assessing and continuously improving resilient safety culture in high-reliability organizations (HROs) such as aviation that has a fully functional Safety Management Systems (SMS). Perceptions on the relationship between four (4) organizational management factors (Principles, Policy, Procedures, Practices) and resilient safety culture in a collegiate aviation program was assessed using an online survey instrument drafted using Reason (2011) concept on safety resilience. Sample was drawn from aviation students, flight instructors, faculty and administrators. Structural Equation Model (SEM) and Causal Path Analysis (CPA) techniques were used to assess conceptual models. Results suggest good …

Elmer Fem-Dakota: A Unified Open-Source Computational Framework For Electromagnetics And Data Analytics, Anjali Sandip

Mechanical Engineering Faculty Publications

Open-source electromagnetic design software, Elmer FEM, was interfaced with data analytics toolkit, Dakota. Furthermore, the coupled software was validated against a benchmark test. The interface developed provides a unified open-source computational framework for electromagnetics and data analytics. Its key features include uncertainty quantification, surrogate modelling and parameter studies. This framework enables a richer understanding of model predictions to better design electric machines in a time sensitive manner.

Mechanical Engineering Posters and Presentations

Traditionally, multi-physics/phase simulation software programs lack tools for uncertainty quantification and optimization. More recently, there is a growing body of research that has integrated these tools into multi-physics/phase simulation software programs [1-4]. Building on this methodology, the study integrated open-source software programs, OpenFOAM [5] for multi-physics/phase simulations and DAKOTA [6] for optimization and uncertainty quantification. Furthermore, the coupled software was successfully applied to benchmarks. The overarching goal was to develop an open-source framework for multi-physics/phase simulations, optimization and uncertainty quantification. The applications of this open-source framework span several industries ranging from aerospace and energy to healthcare and manufacturing.

Evaluation Of Bridge Decks With Overlays Using Impact Echo, A Deep Learning Approach, Sattar Dorafshan, Hoda Azari

Civil Engineering Faculty Publications

In this paper, the feasibility of using deep learning models (DLMs) for evaluation of bridges with overlay systems is investigated. Several laboratory-made concrete specimens with artificial subsurface defects and overlay systems (bonded and debonded) made of cement and asphalt overlay materials were tested using impact echo (IE). One-dimensional (1D) and two-dimensional (2D) convolutional neural networks (CNNs) were developed, trained, and tested on the IE data. The proposed 1D CNN was the most successful in detecting debonding and subsurface defects; it achieved an average accuracy of 0.68 on the cement overlay specimens and 0.58 for asphalt overlay specimens. Maps of the …

Assessing Cultural Drivers Of Safety Resilience In A Collegiate Aviation Program, Daniel Kwasi Adjekum, Marcos Fernandez Tous

Aviation Faculty Publications

Organizational safety resilience is a key factor in sustaining an effective safety management system (SMS) in high-reliability organizations (HROs) such as aviation. Extant research advocates for monitoring, assessing and continuously improving safety in an organization that has a fully-functional SMS. Safety resilience provides a buffer against vulnerabilities. Extant research also suggests a paucity in terms of a measurement framework for organizational safety resilience in collegiate aviation operations. A quantitative approach using Reason’s safety resilience concept (Reason, 2011) is used to assess organizational safety resilience in a collegiate aviation program with an active conformance SMS accepted by the FAA. A sample …

Comparative Scoping Study Report For The Extraction Of Microalgae Oils From Two Subspecies Of Chlorella Vulgaris, Jasmine Kreft, Eric Moe, Nicholas Garcia, Andrew Ross, Wayne Seames

Chemistry Faculty Publications

The production of microalgae as a fatty acid oil resource for use in biofuels production is a widespread research topic at the lab scale. Microalgae contain a higher lipid content on a dry-weight basis compared to oilseeds such as soybeans. Additionally, the growth and cultivation cycle of microalgae is 15 days, in comparison to soybeans, for which the cycle occurs once or twice annually. However, to date, it has been uneconomical to produce microalgae oils in a world-scale facility due to limitations in cultivating microalgae at commercial scales. Recent developments suggest that the use of heterotrophic microalgae may be economically …

Using Geothermal Energy To Reduce Oil Production Costs, Will Gosnold, Mark Ballesteros, Dongmei Wang, Josh Crowell

Geology and Geological Engineering Faculty Publications

The economic impact of the Covid-19 pandemic on the oil industry has been devastating. The decline in demand and price collapse have been particularly disruptive for shale oil extraction which is inherently more expensive than conventional operations. Survival and continuing operations will depend partly on reducing operating costs, and a ubiquitous and substantial cost in oil production is electrical power used primarily for pumping the wells. The Bakken in North Dakota play is particularly vulnerable because there is not an adequate electrical grid in the region. Many Bakken fields rely on generators burning propane, gasoline or diesel fuel at costs …

Deep Direct Use Geothermal Energy In The North Dakota Clean Energy Transition Strategy, Al Thibeault, Moones Alamooti, Nnaemeka Ngobidi, Will Gosnold

Geology and Geological Engineering Faculty Publications

The geothermal heat in the Williston Basin is an energy giant that can provide sustainable, renewable, and ecologically sound heat and power for the state of North Dakota (ND). We have known of this resource for decades, but development has been delayed for reasons which can be summed as economic competition from existing fossil fuel energy sources. With the “seismic” shock of the Covid-19 pandemic reverberating through the state’s carbon-centric economy, the timing is ideal for acting quickly to develop this energy resource.

Coincidentally, the State Energy Research Center (SERC) within the Energy & Environmental Research Center (EERC), has recently …

A Relook At Canada’S Western Canada Sedimentary Basin For Power Generation And Direct-Use Energy Production, Catherine Hickson, Katie Huang, Darrell Cotterill, Will Gosnold, Dick Benoit

Geology and Geological Engineering Faculty Publications

The Alberta No. 1 Project, under the terms of Canada’s Federal government’s Emerging Renewable Power Program (ERPP), must produce 5MWe net. The goal of this study was to identify areas where three essential constraining conditions overlap; (1) the temperature gradient is sufficiently high that 120°C brines at depths of 4,500m or less are potentially available, (2) there are formations at the depths targeted with known high fluid flows, and (3) there is adequate existing infrastructure that supports low-cost power grid connection as well as a direct use application. A fluid temperature of at least 120^oC is needed to …
