Power Packet Networks For Wave Energy Converter Arrays, David G. Wilson, Raymond H. Byrne, Steven F. Glover, Tu Anh Nguyen, Rush Robinett, Wayne Weaver, Et. Al

Michigan Tech Patents

One of the biggest challenges for all renewable energy sources (RES) is that they are variable power generators which will require reactive power or energy storage systems (ESS) to provide reliable power quality (ideally power factor of one) at the power grid generation side. The present invention is directed to a power packet network (PPN) for integrating wave energy converter (WEC) arrays into microgrids. Specifically, an array of WECs can be physically positioned such that the incoming regular waves will produce an output emulating an N-phase AC system such that the PPN output power is constant. ESS requirements are thereby …

Salts Removal As An Effective And Economical Method Of Bakken Formation Treatment, Mousa Almousa, Olusegun Stanley Tomomewo, Yeo Howe Lim

Civil Engineering Posters and Presentations

One of the main aims of managing and containing waste disposal in deep rock formations is to safeguard individuals, the surroundings, and the groundwater reserves The elevated salt content of the water produced by the rock formation necessitated an analysis of its chemical composition, including its major ion content, in order to understand the characteristics of the rock Additionally, the total dissolved solids ( in the ND Bakken formation are greater than 300 g/l, which is much higher than the concentration of salt in seawater therefore, it is reasonable to propose a modified process to treat the salts found in …

Comparing Fishbone Drilling And Hydraulic Fracturing In Ultra-Low Permeability Geothermal Reservoirs, Aimene Aihar, Nassim Bouabdallah, Ghoulem Ifrene, Doina Irofti

Petroleum Engineering Posters and Presentations

Harnessing geothermal energy through Enhanced Geothermal Systems (EGS) offers a sustainable and renewable means of tapping the Earth's subsurface heat. However, in ultra-low permeability formations like those found in the Williston Basin, the effectiveness of conventional hydraulic fracturing techniques is limited. This study evaluates the potential of fishbone drilling technology as an alternative approach, focusing on the efficiency and engineering aspects of both methods in the context of geothermal reservoirs with extremely low permeability.

We carried out an extensive literature review, numerical simulations, and case studies to compare fishbone drilling and hydraulic fracturing in EGS applications. Fishbone drilling, which involves …

Evaluation Of Hybrid Prediction Models For Accurate Rate Of Penetration (Rop) Prediction In Drilling Operations, Abdelhakim Khouissat, Mohamed Riad Youcefi, Ghoulem Ifrene, Doina Irofti

Petroleum Engineering Posters and Presentations

The precise prediction of the rate of penetration (ROP) is of utmost importance for optimizing drilling operations and minimizing costs while increasing efficiency. However, the complex and nonlinear nature of the drilling process can pose significant challenges in achieving accurate ROP predictions. To address this challenge, multiple hybrid prediction models have been developed, and their accuracy in ROP prediction has been compared.

To accomplish this objective, we created three different hybrid models, including Artificial Neural Network – Genetic Algorithm (ANN-GA), Artificial Neural Network-Particle Swarm Optimization (ANN-PSO), and Support Vector Regression (SVR) to estimate ROP. These models were trained and tested …

Exploring Underground Hydrogen Storage Options In North Dakota: A Review, Aimen Laalam, Olusegun Stanley Tomomewo

Petroleum Engineering Posters and Presentations

As the world shifts towards a low-carbon future, the demand for efficient, safe, and cost-effective energy storage solutions has become increasingly critical. Hydrogen has emerged as a promising energy carrier with numerous advantages, such as high energy density, zero emission combustion, and versatile applications. Nevertheless, the challenge of effective hydrogen storage remains. This study examines the potential of underground hydrogen storage (UHS) in North Dakota, assessing its opportunities and challenges in supporting the region's renewable energy objectives. North Dakota's unique geological features, abundant renewable energy resources, and growing energy demands make it an ideal location for UHS implementation. This review …

Creation Of A Hyperplane Device For Horizontal Cellular Migration Assays, Nicholas M. Bittner, Nelofar Nargis, Ghoulem Ifrene, Brent Jeffrey Voels, Colin K. Combs

Biomedical Sciences Posters and Presentations

Cell culture studies routinely seek to monitor cell migration in response to chemoattractant stimuli. Common assays of cell migration employ well inserts and vertical cell migration assessment. This approach does not allow real-time monitoring of cell behavior. To address this need, we sought to develop a horizontal culture platform conducive to time course cell assessment changes in migration, morphology, phenotype etc. Modification of a commercial chamber slide allowed us to quantify cell migration in response to a 20% serum gradient. Based upon this finding, we designed and fabricated a prototype chamber slide for high replicate, real time assessment of cell …

Advancing Our Understanding Of Non-Linear Flow Behavior In X-Crossing Fractures Through 3d Printing Technology, Ghoulem Ifrene, Sven Egenhoff, Doina Irofti, Nicholas Bittner, Tyler Newman

Petroleum Engineering Posters and Presentations

Fractured reservoir systems play a critical role in the efficient management of hydrocarbon resources, CO2 storage, and geothermal energy extraction. Understanding the behavior and characteristics of these systems is essential for optimizing recovery, reducing carbon footprint, and increasing efficiency. However, fractures within reservoir systems create complex geometries and can make fluid flow behavior complex and difficult to predict. Replicating these complex geometries in the laboratory has been challenging, but advancements in 3D printing technology have made it possible to create accurate models of rough-walled fracture geometries. In this study, the impact of geometric characteristics on fluid flow behavior in connected …

Slowly Changing Dimensions And Fast Changing Facts - The Story Of The Traditional Data Warehouse, Vishnu Pendyala

Open Educational Resources

This presentation, "Slowly Changing Dimensions and Fast Changing Facts - The Story of the Traditional Data Warehouse," explores how to generate actionable insights from organizational performance data. It begins by discussing the challenges of generating insights directly from existing databases and introduces the concept of data cubes for efficient aggregate storage. The core of the presentation focuses on dimensional modeling, particularly the Star Schema, as a solution for analytical processing needs that cannot be met by transactional systems. It details the characteristics of fast-changing fact tables (long, lean, numeric) and slowly changing dimension tables (descriptive, wide, containing strings and numbers). …

Development Of A Biobased Carbon Adsorbent For Treating Emerging Contaminants In Recycled Water On The International Space Station, Savanna Vacek, Madeline Carroll, Gabson Baguma

Undergraduate Research Symposium Posters

The International Space Station (ISS) operates as a closed system. Water is recycled from humidity and urine and held in a wastewater tank; part of the Water Processing Assembly (WPA). Potable treated water is used indirectly in the Sabatier Reactor.The Sabatier Reactor is a key component in the Environmental Control and Life Support System (ECLSS). Three main functions of ECLSS: water recovery, air revitalization, and oxygen generation Sabatier Reactor recently failed due to contamination of DMSO2, dimethyl sulfone, and DMSD, dimethylsilanediol. DMSO2 and DMSD are emerging contaminants that are not removed by the media used in the WPA due to …

Identifying The Optimal Range Of Fine Ground Waste Glass As Cement Replacement, Stephanie Taylor

Undergraduate Research Symposium Posters

The viability of finely ground waste glass as cement replacement is linked to the amount of time the concrete is allowed to cure. Testing beyond 91 days was rare, with only one study using an entire year. Replacement levels below 25% provided the best results in compressive strength. The parameters for future testing derived from this literature review will use ASTM C39/C39M-21 to test the compressive strength of specimens with 0%, 10%, 15%, 20% and 25% finely ground glass replacing OPC with measurements taken at 1, 7, 28, 56, 90, 182 and 365 days of curing.
