Comparison of innovated thermoplastic polyurethane and commercial helmet lining technology in mitigating concussions as measured by linear accelerations and risk of head injury during simulated horizontal impacts to the head
(2020)Advances in helmet designs and technology have not completely eliminated the incidence of mild traumatic brain injuries (mTBI) in the sport of ice hockey. One issue that concerns researchers is that the vinyl nitrile ... -
Dynamic model and control of vehicles
(2006)In this thesis the author develops a 14 degrees-of-freedom (DOF) full-car model. The model draws from and improves upon features and setups of certain existing vehicle dynamics models. The proposed model provides a means ... -
Dynamic modeling and analysis of circumferential and spiral waves in piezoelectric cylinders
(2012)Understanding the dynamic characteristics of ultrasonic guided wave in structures is important, as it is one of the methods that are widely used in many different areas of industrial sectors and inspections, such as ... -
Dynamics of single axle rail wheelsets incorporating profiled wheels and rails
(2009)This thesis presents the theories and numerical simulations in regard to the behaviour of a single-axle railway wheelset commonly used in cargo rail cars. Specifically, creep forces, dynamic models, real wheel-rail profiles, ... -
Noise attenuation and energy harvesting using helmholtz resonator connected to rectangular cavity
(2025)This thesis investigates the dual functionality of a Helmholtz Resonator (HR) coupled with a rectangular cavity for noise attenuation and small-scale energy harvesting. The study explores the integration of a piezoelectric ... -
Nonlinear dynamics of railway wheelsets incorporating randomness
(2007)The thesis is to investigate the dynamic behavior of a single-axle railway wheelset and identify its chaotic behavior by means of time history, phase portrait, Lyapunov exponents, information dimension, bifurcation diagram ... -
Numerical analysis of discontinuous structures: static and dynamic
(2018)Discontinuous beam structures can be found in various applications such as adhesive bonded joints and piezoelectric energy harvesters. In adhesive bonded joint design, the single lap joint is commonly used and is constructed ... -
Towards examining the effectiveness of boxing headguards with thermoplastic polyurethane in mitigating acceleration and risk of head injury using a dynamic head model
(2021)The sport of boxing historically symbolises a high-risk injury sport due the number of concussions occurring on athletes. Indeed, boxing has shown to have the highest rate of concussions of any individual male sport. ...
