Improved Accuracy in Optical Motion Capture Measurements Leads to Increased Sensitivity to Kinematic Changes
(2016-08-18)Clinical optical motion capture allows us to obtain kinematic and kinetic outcome measures that aid clinicians in diagnosing and treating different pathologies affecting healthy gait. The long term aim for gait centres is ... -
Improvements on Single Point Incremental Forming Through Electrically Assisted Forming, Contact Area Prediction and Tool Development
(2013-11-29)Single Point Incremental Forming (SPIF) is a die-less sheet metal forming method. Because SPIF does not use custom tooling, this process allows for parts to be made at low cost and short lead times. In this thesis electric ... -
IMU-Based Lower-limb joint angles: A comparison of methods
(2015-12-21)Inertial measurement units (IMUs) are a popular option for human movement analysis. The untethered, self-contained nature of IMUs overcomes many limitations of conventional measurement systems. The potential of IMU systems ... -
In-plane plane strain testing to evaluate formability of sheet steels used in tubular products
(2007-09-28)In order to effectively and efficiently hydroform new automotive components, the formability of new tubular steels must be evaluated. Standard forming limit diagrams have been used for decades to evaluate and predict the ... -
Industrial-Scale Autonomous Vehicle Path Following by Feedback Linearized Iterative Learning Control
This work describes and demonstrates, through simulation and field trials, a technique for autonomous wheeled vehicle path following that uses iterative learning control (ILC) performed in a feedback linearized space to ... -
INERTIAL SENSORS FOR KINEMATIC MEASUREMENT AND ACTIVITY CLASSIFICATION OF GAIT POST-STROKE
(2013-08-29)The ability to walk and negotiate stairs is an important predictor of independent ambulation. The superposition of mobility impairments to the effects of natural aging in persons with stroke render the completion of many ... -
Inertial Sensors in Estimating Spatio-Temporal Parameters of Walking: Performance Evaluation and Error Analysis
(2011-08-23)The portability, ease of use and improved accuracy of miniature inertial sensors brought by current microelectromechanical system (MEMS) technology has inspired researchers to develop human movement monitoring system with ... -
The Inhomogeneous Microstructure and Deformation of Similar and Dissimilar Al-Zn Containing Mg Friction Stir Welds
The magnesium-based aluminum-zinc alloys have excellent stiffness to weight ratios, and may be combined by friction stir welding to expand the possible applications. The high aluminum alloy AZ80 in particular has the ... -
INITIATION OF DELAYED HYDRIDE CRACKING IN Zr-2.5Nb MICRO PRESSURE TUBES
(2009-04-25)Pressure tubes pick up hydrogen while they are in service within CANDU reactors. Sufficiently high hydrogen concentration can lead to hydride precipitation during reactor shutdown/repair at flaws, resulting in the potential ... -
Integrated Energy System for a High Performance Building
Integrated energy systems have the potential to reduce of the energy consumption of residential buildings in Canada. These systems incorporate components to meet the building heating, cooling and domestic hot water load ... -
Investigating Catalyst Coated Membrane Equilibration Time For Polymer Electrolyte Membrane Fuel Cell Manufacturing
Mercedes-Benz Canada Inc., Fuel Cell Division, manufactures polymer electrolyte membrane fuel cell stacks for use in vehicles. The manufacturing line is being optimized for efficiency and quality control, in order to uphold ... -
An Investigation of Nano-voids in Aluminum by Small-angle X-ray Scattering
(2008-04-28)Small angle x-ray scattering (SAXS) with synchrotron radiation was used to characterize nano-sized voids in different nominally pure aluminum (Al) alloys produced by quenching. The scattering signal from nano-voids is ... -
Investigation of Performance Enhancements for a Liquid-Desiccant Solar Air-Conditioner
(2016-06-27)Thermally driven liquid-desiccant air-conditioners (LDAC) are a proven but still developing technology. LDACs can use a solar thermal system to reduce the operational cost and environmental impact of the system by reducing ... -
An Investigation of Rat Vertebra Failure Behaviour Under Uniaxial Compression Through Time-Lapsed Micro-CT Imaging
(2013-11-22)Osteoporosis is a bone degenerative disease characterized by reduced bone mass, quality and strength, along with changes in microarchitecture and increased incidence of fracture. The significant economic and social costs ... -
Investigation of the Causal Factors for Enrollment and Satisfaction in Engineering
(2015-10-03)Undergraduate students at Queen’s University were surveyed and interviewed to examine the factors behind engineering program selection and academic transfer to engineering. The surveys were completed by 416 2nd-4th year ... -
AN INVESTIGATION OF THE FLOW THROUGH CHECK VALVES IN A UNIFLOWTYPE TWO-STROKE ENGINE
(2010-07-13)An innovative two-stroke engine has been under development at Queen’s University. Traditional crankcase-scavenged two-stroke engines have laboured to meet emissions standards and achieve fuel economy comparable to four-stroke ... -
INVESTIGATION OF THE STABILITY OF C15 LAVES PHASE STRUCTURES IN BCC IRON BY MOLECULAR DYNAMICS METHOD
(2016-05-02)A new class of interstitial clusters which present a structure of C15 Laves phase has been theoretically predicted in bcc iron. However, these C15 clusters have never been identified experimentally. In this thesis, molecular ... -
Investigation of Vibration Related Signals for Monitoring of Large Open‐Pit Rotary Electric Blasthole Drills
(2010-09-27)This thesis investigated the monitoring and analysis of signals related to the vibration of large rotary blasthole drills. The research focused on a machine with electric drilling actuators: such machines are used as primary ... -
