Continuum Modelling and Vibration Analysis of String-Harnessed Structures
(University of Waterloo, 2017-09-14)Power and signal cables in recent years have been observed to constitute a major component in the dynamic behaviour of space structures. In a typical system, the cables-to-payload mass ratio can be as high as 20%. Ignoring ... -
Controller Design for Active Vibration Damping with Inertial Actuators
(University of Waterloo, 2019-05-06)In the machining industry, there is a constant need to improve productivity while maintaining required dimensional tolerances and surface quality. The self-excited vibration called chatter is one of the main factors limiting ... -
Low-Frequency Piezoelectric Energy Harvester with Novel 3D Folded Zigzag Design and High Power Density
(University of Waterloo, 2018-07-09)Cantilevers have been widely used for vibration energy harvesting applications using piezoelectric materials due to their simple geometries, frequency tune-ability, and closed form analytical solution. Recent studies have ... -
A Multi-class BCI based on Somatosensory Imagery
(Institute of Electrical and Electronics Engineers, 2018-06-18)In this study, we investigated the performance of a multi-class brain-computer interface (BCI). The BCI system is based on the concept of somatosensory attentional orientation (SAO), in which the user shifts and maintains ... -
A multi-class tactile brain-computer interface based on stimulus-induced oscillatory dynamics
(Elsevier, 2017-07-24)We proposed a multi-class tactile brain-computer interface that utilizes stimulus-induced oscillatory dynamics. It was hypothesized that somatosensory attention can modulate tactile induced oscillation changes, which can ... -
Performance of Brain-Computer Interfacing Based on Tactile Selective Sensation and Motor Imagery
(Institute of Electrical and Electronics Engineers, 2017-11-03)A large proportion of users do not achieve adequate control using current non-invasive Brain-computer Interfaces (BCI). This issue has being coined “BCI-Illiteracy”, and is observed among BCI modalities. Here, we compare ...
