Acute cardiopulmonary responses to different intensities of exercise in healthy older adults
(2019-12-01)
The overall purpose of this thesis was to study the acute cardiopulmonary responses to different intensities of exercise in healthy older adults. Thirty healthy older males and females (69.6 ǂ 6.2 yrs.; males n = 15) ...
Compensation in movement behaviours following exercise of different intensities in older adults
(2019-08-01)
The overall purpose of this thesis was to assess compensation in movement behaviours of older adults following exercise. Participants (n=28, 69.7±6.5 years) completed the following exercise protocols in random order, one ...
The impact of assisted dying on suicidality: a synthetic control analysis of population suicide rates
(2019-06-01)
Adoption of assisted dying is growing, but one argument against these policies is that they cause a suicide contagion, thus increasing suicides. Evidence for the assisted dying-suicide link does not currently exist, and ...
Multimodal series elastic actuator for human-machine interaction with applications in robot-aided rehabilitation
(2019-11-01)
Series elastic actuators (SEAs) are becoming an elemental building block in collaborative robotic systems. They introduce an elastic element between the mechanical drive and the end-effector, making otherwise rigid structures ...
Design and development of an autonomous scaled electric combat vehicle
(2019-04-01)
Current literature pertaining to multi-steerable mobile robots and the progression of military vehicles in the past few decades suggest a lack of effort in pursuing advanced technologies in this joint area. As a result, a ...
Simulation of microgrid system and low-cost wireless communication network
(2019-08-01)
The MATLAB/SIMULINK model of a microgrid system is presented in this thesis. The microgrid consists of a converter-fed distributed generator photovoltaic array with maximum power point tracking, a converter-fed battery ...
Controlling the Vienna rectifier using a simplified space vector pulse width modulation technique
(2019-11-01)
In this thesis, a simplified Space-Vector Pulse-Width-Modulation (SVPWM) technique for the Vienna rectifier is introduced to reduce the computational burden, the switching losses and the Total-Harmonic-Distortion (THD). ...
Damping acoustic pressure pulsations in pipelines using Helmholtz resonators
(2019-05-01)
In industrial piping systems, centrifugal and reciprocating turbomachinery generate acoustic pressure pulsations, which propagate into the pipeline and interact with piping components, potentially causing vibrations, ...
Optimal structure and efficient algorithm for max-min fair multi-group multicast beamforming
(2019-09-01)
In this thesis, we consider the max-min fair (MMF) multi-group multicast beamforming design to maximize the minimum signal-to-interference-plus-noise ratio (SINR) subject to transmit power limit. We obtain the optimal ...
Design of robust active trailer steering controllers for multi-trailer articulated heavy vehicles using software/hardware-in-the-loop real-time simulations
(2019-08-01)
Due to their remarkable economic and environmental benefits, Multi-Trailer Articulated Heavy Vehicles (MTAHVs) have been frequently adopted by the trucking industry. Despite the above advantages, MTAHVs exhibit two particular ...
