The effect of different manual task simulation methods on hand and forearm demand estimates
(University of Waterloo, 2009-08-28)The force exerted during manual tasks is a dominant risk factor for upper-limb musculoskeletal disorders. To identify tasks that may lead to fatigue over a shift, or increase the risk of injury, the demands placed on the ... -
The effect of different methods to identify, and scenarios used to address energy intake misestimation on dietary patterns derived by cluster analysis
(BioMed Central, 2021-05-08)Background: All self-reported dietary intake data are characterized by measurement error, and validation studies indicate that the estimation of energy intake (EI) is particularly affected. Methods: Using self-reported ... -
Effect of Dissipation on the Dynamics of Superconducting Single Electron Transistors
(University of Waterloo, 2012-08-30)In this thesis, I will present the experimental results of the dynamics of superconducting single electron transistors (sSETs), under the influence of tunable dissipation. The sSET, consisting of two dc SQUIDs in series ... -
