Axial twist loading of the spine: Modulators of injury mechanisms and the potential for pain generation.
(University of Waterloo, 2008-05-26)There are several reasons to research the effects of axial twist exposures and the resulting loading on the spine. The lack of consensus from the limited work that has previously examined the role of axial twist moments ... -
COUPLED DYNAMICS OF CABLE-HARNESSED STRUCTURES: ANALYTICAL MODELING AND EXPERIMENTAL VALIDATION
(University of Waterloo, 2019-05-24)This thesis presents analytical models to study the vibration characteristics of cable-harnessed beam structures motivated by space structure applications. The distributed parameter models proposed in this work considers ... -
The Impact of Portland Cement on the Performance of Cold In-Place Recycled Pavement
(University of Waterloo, 2022-12-06)In place recycling of existing asphalt pavement is a rehabilitation strategy, which the Ministry of Transportation Ontario (MTO) adopted decades ago. Asphalt emulsion is the most common type of bitumen stabilizing agent ... -
Interconnected Air Suspensions with Independent Height and Stiffness Tuning
(University of Waterloo, 2014-05-02)Suspensions play a crucial role in vehicle comfort and stability. Different types of suspensions have been proposed to fulfill the essential characteristics of vehicle suspensions. A semi-active suspension with adjustable ... -
Low Mobility Cable Robot with Application to Robotic Warehousing
(University of Waterloo, 2014-10-17)Cable-based robots consist of a rigid mobile platform connected via flexible links (cables, wires, tendons) to a surrounding static platform. The use of cables simplifies the mechanical structure and reduces the inertia, ... -
Novel Semi-Active Suspension with Tunable Stiffness and Damping Characteristics
(University of Waterloo, 2013-01-15)For the past several decades there have been many attempts to improve suspension performance due to its importance within vehicle dynamics. The suspension system main functions are to connect the chassis to the ground, ... -
A procedure for determining parameters of a simplified ligament model
(Elsevier, 2017-11-03)A previous mathematical model of ligament force-generation treated their behavior as a population of collagen fibres arranged in parallel. When damage was ignored in this model, an expression for ligament force in terms ... -
A Risk Based Approach to Module Tolerance Specification
(University of Waterloo, 2014-04-24)This research investigates tolerance strategies for modular systems on a project specific basis. The objective of the proposed research is to form a guideline for optimizing the construction costs/risks with the aim of ... -
TIME VARYING GENDER AND PASSIVE TISSUE RESPONSES TO PROLONGED DRIVING
(University of Waterloo, 2008-08-15)Background: Prolonged sitting in an automobile seat may alter the passive tissue stiffness of the lumbar spine differentially in males and females. Gender specific ergonomic interventions may be indicated for the ...
