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.

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 ... -
Numerical seakeeping predictions of shallow water effect on two ship interactions in waves.
(Dalhousie University, 2001) -
Numerical simulation and experimental modeling of matrix/fracture flow in porous media.

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 ... -
NUMERICAL STUDY OF THE EFFECTS OF FINS AND THERMAL FLUID VELOCITIES ON THE STORAGE CHARACTERISTICS OF A CYLINDRICAL LATENT HEAT ENERGY STORAGE SYSTEM
(2010-09-15)This thesis work presents a numerical study of the effects of fins and thermal fluid velocities on the storage characteristics of a cylindrical latent heat energy storage system (LHESS). The work consists of two main ... -
NUMERICAL STUDY OF THE IN-PLANE BEHAVIOUR OF CONCRETE MASONRY INFILLS BOUNDED BY STEEL FRAMES
(2016-10-06)A finite element study was conducted to investigate the in-plane behaviour and strength of masonry infills bounded by steel frames with the focus on the effect of several influential parameters. In this study, two finite ... -
Numerical Study of Three-dimensional Circulation and Hydrography in Halifax Harbour Using a Nested-grid Ocean Circulation Model
(2010-12-21)Halifax Harbour is one of the world's largest natural harbours and has significant environmental and economic value. A good understanding of oceanographic processes is required for pollution control and sustainable ... -
Nurses are Key Members of the Abortion Care Team: Why aren’t Schools of Nursing Teaching Abortion Care?
(York University, 2019-12-10)Abortion is a common and safe procedure in Canada, with the Canadian Institute for Health Information reporting approximately 100,000 procedures per year. Yet access remains problematic. As abortion is unrestricted by ...
