Optimal control of a heat exchange process using a perturbation signal

Based on the recent summit in Copenhagen, it is obvious that all nations are taking climate change seriously. One of the areas that countries are focusing on is reducing their greenhouse gas emissions by reducing their overall energy consumption. Industrial Countries are encouraging consumers to buy appliances that are deemed energy efficient using an Energy Star rating.

Invstigation of High Temperature Tribological Behavior and Wear Mechanism of Stellite Alloys

Many industrial processes require materials that combine high strength at elevated temperatures with good corrosion and wear resistance. Superalloys are the only materials which can serve in such conditions, because of their outstanding high-temperature properties and excellent corrosion and wear resistance. However, due to limitation of testing facilities and difficulty of experimental operations, the data of these properties at elevated temperatures for these alloys are very limited, which has limited the application of these high temperature materials.

Electric Vehicle Components Modeling

Vehicle electrification poses considerable challenges on chassis architecture, design of vehicle control and power management systems. Moreover, it tends to induce variations in the sprung and unsprung masses and load distributions. A combination of these has a significant impact on vehicle system dynamics and stability. Thus, development of next-generation electric vehicles

Hierarchical Thermal Transport in Electronic Devices: Nano-Scale and Transistor-Level Modelling

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.

Experimental investigation of anaerobic digestion conducted under controlled conditions: data collection and analysis

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

Vibration Assisted Nano Mechanical Machining through Atomic Force Microscope

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.

Examining Human Standing Balance Response with Independent Ankle Control

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
