Experimental Modal Analysis of Business Jet Fuselage Tail Section Sub-Assemblies
Experimental modal testing is a technique through which the dynamic response characteristics of a system can be found. Parameters such as the natural frequencies and mode shapes of a system can be extracted through ... -
Exploring Engineering Students' Interpretations of Success
This study used quantitative methods to explore Canadian undergraduate engineering students’ interpretations of their success. The amorphous term “student success” is used by students, educators, academics, engineering ... -
A Mesh Independent Approach for Multi-Joint Topology Optimization
Topology optimization (TO) has been identified as a leading method to reduce weight in both component and assembly level design. Optimum loadpaths within a designable region are determined, providing non-intuitive designs ... -
INVESTIGATING MEASUREMENT MODALITIES FOR INTEGRATED USE IN OVERUSE INJURY RESEARCH
Running is a common form of exercise enjoyed throughout the world. Unfortunately, it poses a significant risk of injury, as up to 70% of runners suffer an overuse injury within a one-year period. Previous research indicates ... -
Effect of Heating Cycles on Microstructure of Dissimilar Friction Stir Welded Age-Hardenable Aluminum Alloys
The effect of heating on microstructural changes in dissimilar friction stir welding of aluminum alloys AA6022 and AA7075 was studied. The challenge in welding these alloys is the strength loss in the heat affected zone ... -
Direct numerical simulations of aeolian noise generated by a circular cylinder in subsonic and transonic conditions
The aeolian noise generated by a circular cylinder is an important benchmark aero-acoustic problem. The overall goal of this thesis is to identify sound sources, isolate the radiating components from the non-radiating ... -
Arch-rivals? The roles of the windlass and arch-spring mechanisms in running
The human foot is an integral part of locomotion due to its broad range of function. Its versatility derives from mechanisms that originated from cadaveric or static experiments, and were extrapolated to locomotion. Two ... -
Feature Engineering and End-to-End Deep Learning in Tool Wear Monitoring
Machinery health monitoring is an important tool for improving the productivity of today's manufacturers. Two data-driven techniques are prominent in machinery health monitoring: feature engineering and end-to-end deep ... -
Topology Optimization and Additive Manufacturing-based Parts Consolidation of an Aircraft Avionics Pedestal
An avionics pedestal is the structure located in the center of the cockpit that houses the flight controls and critical electronics for the operation of the aircraft. This thesis presents a parts consolidation design ... -
Fluid-Structure Interaction of Large Viscoelastic Vessels Under Pulsatile Conditions
The current threshold diameter for aortic aneurysm repair is based on Laplace's law. However, aneurysms below this threshold have undergone dissection, while some larger aneurysms remain stable. An accurate understanding ... -
Force-Based Control of UGVs by Using Physical Human-Robot Interaction
Humans apply directional forces to move wheeled objects in various everyday applications such as maneuvering a loaded cart, a lawnmower, or moving a stretcher. The heavier the object, the higher the magnitude of force ... -
Computational Modal Analysis of Prestressed Half Scale Generic Business Jet Substructures
Computational modal analysis via finite element analysis is a well-established method for modal parameter estimation. The resultant modal parameters are crucial inputs for vibro-acoustic finite element analyses and require ... -
Structural Design of a Morphing Serpentine Inlet Using a Multi-Material Topology Optimization Methodology
A promising avenue for development in the aerospace industry involves relocation of engines from conventional locations beneath the wings, to within the aircraft fuselage. Aircraft with these so-called embedded engines ... -
Application of Nano-Scale Characterization Techniques in Failure Analysis of Stress Corrosion Cracking in an Alloy C-276 Pull Rod
A failure analysis was performed on an alloy C-276 pull rod which underwent unexpected brittle, fracture after exposure to nuclear-relevant, high temperature aqueous environments: Pb-contaminated alkaline (8.5 < pH300C < ... -
Validation of a Markerless Motion Capture System for Human Movement Analysis
Three-dimensional human movement analysis is a widely used tool in clinical and research biomechanics to provide comprehensive 3D representations and quantification of individuals’ movement patterns, particularly gait. ... -
Numerical Investigation of an Aircraft Thermal Management System
Thermal management requirements in modern aircraft have been increasing over time, driven by the increase in the thermal loads generated by a variety of electronic components and hydraulic systems. A literature review has ... -
Causes and Effects of Variation in Wrist Range of Motion: Investigating the Kinematics of the Proximal Carpal Row
Due to the complex nature of the wrist, we still do not fully understand how the healthy wrist functions. There are few muscle insertions at the wrist, so bone motion is induced by passive ligaments and bone to bone contact, ... -
Evaporative Spray Cooling of Hot Air Flow from a Round Nozzle: Experiments and CFD
Evaporative spray cooling is a technique that utilizes the latent heat of evaporation of a cold liquid spray to rapidly cool a hot gaseous source. During evaporation the liquid droplets are fixed at their boiling point, ... -
Environmentally Friendly Recycling of Lithium Ion Batteries
Recycling lithium ion batteries (LIBs) and using their recovered materials to make new ones has many economic, social, and environmental benefits. The greatest benefits come from recycling metals from cathode active ... -
Automated Detection of Helium Bubbles in Inconel X-750 and Modeling Their Effect on its Mechanical Properties
It is well known that the presence of pores has an effect on the mechanical properties of materials. A figure case is X-750, a Ni-based alloys exposed to neutron irradiation in nuclear reactors. Interactions with neutrons ...
