Numerical Analysis of Longwall Mining Layout for a Wyoming Trona Mine
(Elsevier, 2016)At Solvay Mine, located in southwestern Wyoming, a subhorizontal trona seam is mined at depths of between 460-490 m using mechanized room-and-pillar and longwall mining methods. The stratigraphy at the mine generally ... -
NUMERICAL AND EXPERIMENTAL STUDY OF BEHAVIOUR OF REINFORCED MASONRY COLUMNS
(2023-11-07)This study investigated the behaviour of reinforced concrete (RC) masonry columns with an emphasis on assessing the moment magnifier method specified in the Canadian masonry design standard CSA S304-14 for design of masonry ... -
NUMERICAL AND EXPERIMENTAL STUDY OF GROUTED ROCK BOLTS AND THEIR DEFECTS USING ULTRASONIC GUIDED WAVES
(2013-05-23)A rock bolt installed in field has only one short exposed end on the rock surface. This condition has posed challenges in field instrumentation and made it difficult to use the ultrasonic guided wave method for rock bolt ... -
Numerical computation of multi-hull ship resistance and motion.

Numerical Investigation of Fillet Welds in HSS-to-Rigid End-Plate Connections
(American Society of Civil Engineers, 2017)This paper presents a finite element (FE) investigation on the behavior of fillet-welded hollow structural section (HSS) rigid end-plate connections, wherein the entire weld length is effective. The FE models are validated ... -
Numerical Investigation of the Strength and Failure Mechanism of Hard Rock Pillars Under Compressive and Shear Loading Conditions
(2023-09-27)Pillars are important support elements in underground mines. A reliable design of hard rock pillars requires a thorough understanding of their strength and failure mechanisms. While several investigations have been conducted ... -
Numerical Modeling and Optimization of Open-Ocean Aeration Systems
(2018-04-30)The coastal regions of Nova Scotia are prone to warmer ocean temperatures resulting in lower dissolved oxygen (DO) levels during the summer months. DO levels below 6 mg/L lead to reduced feed conversion, growth, and welfare ... -
Numerical modeling of a laterally heterogeneous lithosphere under extension: Strength contrasts and rifting of a metasomatized craton
(2015)The heterogeneous composition of the lithosphere affects the way it deforms under extension. This thesis investigates the effects of heterogeneities that introduce compositional, thermal, and thickness contrasts within an ... -
Numerical modeling of Atlantic hurricanes moving into the middle latitudes.
(Dalhousie University, 2006) -
Numerical Modeling of Concrete-Filled Fiber-Reinforced Polymer Piles
(2019-11-06)Although many studies have been conducted on the structural behavior of concrete-filled fiber-reinforced polymer (FRP) tube (CFFT), the soil-structure interaction of CFFT piles was not previously considered. In this study, ... -
Numerical Modeling of Large-Displacement Fluid-Structure Interaction: Preliminary Study Aimed at Analysis of Heart Valve Dynamics
(2012-08-22)The demand for artificial heart valve replacements is increasing as a result of birth defects, ageing and disease. Collaboration between engineers, biologists and mathematicians is necessary to handle problems related to ... -
Numerical Modeling of Salt Tectonics at Rifted Continental Margins
(2016-09-02)This thesis applies finite element numerical modeling to a range of projects investigating salt tectonics at rifted continental margins. Both two-dimensional and fully three-dimensional models are used. The first project ... -
Numerical Modeling of the Lateral Behavior of Concrete-Filled FRP Tube Piles in Sand
(ASCE, 2020-08-01)In this study, a numerical model is developed to study concrete-filled FRP tube (CFFT) pile behavior and interactions with foundation soil under lateral loading. The model, based on nonlinear finite element analysis (NFEA) ... -
Numerical Modelling of Integral Abutment Bridges
(2021-11-02)Integral Abutment Bridges (IABs) are well known for their lower construction and maintenance costs by eliminating expansion joints and bearings. The flexible piles supporting the end-span abutments offer the possibility ... -
Numerical Modelling of Vehicle Loads on Buried Orthotropic Steel Shell Structures
(2010-11-26)An investigation was performed for live load forces applied to soil-steel structures under shallow backfill depths, specifically a long span deeply corrugated box culvert. The work was also relevant to other types of ... -

A Numerical Study of Dual Core Surface Plasmon Resonance-based Photonic Crystal Fiber Biosensors.
(2024-04-29)Photonic crystals (PCs) are periodic material structures in the optical domain. Felix Bloch developed a theory that describes how electron waves behave in the periodic structure of solids such as semiconductors. The same ... -
Numerical study of sea ice dynamics and wave-ice interactions in the marginal ice zone
(2021-04-30)The Marginal Ice Zone (MIZ) is a highly dynamic region between the open ocean and the inner ice pack. The ice over this region is subjected to waves, introducing new forces but also changing the ice from a cohesive material ... -
