Salts Removal As An Effective And Economical Method Of Bakken Formation Treatment, Mousa Almousa, Olusegun Stanley Tomomewo, Yeo Howe Lim
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 …
Sustainable Management Of Dams And Reservoirs In North Dakota: Sediment Transport Characterization, Adewale Ajao, Yeo Howe Lim
Sustainable Management Of Dams And Reservoirs In North Dakota: Sediment Transport Characterization, Adewale Ajao, Yeo Howe Lim
Civil Engineering Posters and Presentations
Selected reservoirs in the state of North Dakota was surveyed to assess their storage capacity, sedimentation characteristics, water quality parameters, and check for leakage. The purpose of the study is to understand the dynamic of reservoir sedimentation in North Dakota and the effect on its resiliency and sustainability. The HYCAT, which is an autonomous surface vehicle, was interfaced with a side scan sonar and global positioning system. The side scan sonar soundings at a determined frequency was used to measure reservoir bed level and deposited sediments while the positioning system would provide information along the grid lines. Additionally, this bathymetry …
Evaluation Of Bridge Decks With Overlays Using Impact Echo, A Deep Learning Approach, Sattar Dorafshan, Hoda Azari
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 …
Thin-Walled Steel Tubular Circular Columns With Uniform And Graded Thickness Under Bidirectional Cyclic Loading, Qusay Al-Kaseasbeh, Iraj H.P. Mamaghani
Thin-Walled Steel Tubular Circular Columns With Uniform And Graded Thickness Under Bidirectional Cyclic Loading, Qusay Al-Kaseasbeh, Iraj H.P. Mamaghani
Civil Engineering Faculty Publications
Thin-walled steel tubular circular columns are becoming an increasingly attractive choice as cantilever bridge piers due to their architectural, structural and constructional advantages. This paper aims to evaluate the strength and ductility of thin-walled steel tubular circular columns with uniform thickness (BC) and graded thickness (BGC) under bidirectional cyclic lateral loading in the presence of constant axial force. The analysis is carried out using a finite-element model (FEM) which is substantiated based on the experimental results in the literature. Then, the proposed BGC column with size and volume of material equivalent to the BC column is investigated. As a part …

Investigation Into The Behavior Of An Open Web Steel Joist Bridge, Zahra Andalib, Piero Caputo, Sattar Dorafshan, Marc Maguire, William Collins

Open web steel joists (OWSJ) have been extensively used in the building industry due to numerous advantages when compared with other structural systems. They are lighter than comparable rolled steel shapes, allowing for faster and less costly construction, in addition to their reduced material costs. However, OWSJ are rarely used for bridge structures. This paper examines the behavior of an OWSJ system in a bridge located at the Nucor plant in Brigham City, Utah.

Mitigating global climate change is a major contemporary topic of research and is of major interest to today’s societies. Developed countries the top contributors to the destruction of the climate with buildings in these countries being one of the reasons. Buildings in developed countries account for 20-40% of the total primary energy consumption. This high-energy consumption produces approximately 36% of the total CO2 emissions since fossil-fuels are the primary source of energy in almost all developed countries. To combat this, researchers have investigated wind energy harvesting technologies that produce electricity while also being considered “green”, or low carbon dioxide emitters. …
