The conventional continuum-based physical relations that describe heat and fluid flow in bulk materials, such as the Navier-Stokes and Fourier equations, break down at sub-continuum scales. The failure of these relations, along with the current trend of miniaturization in man-made devices and wide spread use of nano-structured systems, urge for development of new computational techniques capable of modelling sub-continuum physical phenomena. This project specifically studies the thermal transport modelling in nano‐structured systems.
Anaerobic digestion is an environmentally-friendly process that breaks down biomass into simpler, more stable components, while simultaneously capturing energy in the form of a methane-rich biogas. Digesters are usually used to treat wastes, such as at municipal waste facilities, or from livestock farms. However, anaerobic digesters are not very reliable, suffering from occasional “digester upsets”. Consequently, anaerobic digestion is less attractive to industry as compared to other less environmental alternatives. The reason behind this unreliability lies in the complexities of anaero
The objectives of this proposed research are the development of a piezoelectric actuator system to assist nano machining by minimizing forces and the generation of nano-patterns to achieve the desired surface characteristics. The objectives shape the comprehensive technologies required to achieve flexibility, productivity and accuracy in manufacturing miniature systems through a judicious combination of experimental and analytical analysis.
Standing balance is controlled by several inputs, including vision, vestibular sense, and ankle proprioception Research studies in this field actively engage and manipulate these input mechanisms to examine their effects on the balance output, mainly muscle actuation in the lower limbs. While significant progress has been made, it is often difficult to isolate a single input and test its results on the output. The unique Robot for Interactive Sensor Engagement and Rehabilitation (RISER) has been developed in the UBC CARIS
In papermaking, a slurry of wood fibres, which are approximately 2 millimetres long and 30 microns in diameter, is drained through a forming fabric. In this drainage process the fibres get trapped by the fabric as the water drains through it. The actual drainage process is obviously highly complicated because the forming fabric geometry is complex, the wood fibres may interact with one another, and the wood fibres have variable properties. However, we may gain some understanding of dewatering by considering simplified versions of the process.
3D movies and videogames enjoy a rapidly increasing popularity. However, current display technology, especially for home theatres, still requires the viewers to wear assistive devices such as shutter glasses. We are developing 3D display technology that does not require such assistive devices. This technology uses micro-electromechanical elements and synchronized image content display.
