Iterative Learning Control for Precision Motion Control of Microscale and Nanoscale Tracking Systems
Second, we develop a set of time-frequency ILC design and analysis techniques. These techniques are used to custom-design the ILC for precision tracking of aggressive trajectories suitable for rapid microscale and nanoscale manufacturing, assembly, or scanning. They are also useful for applications …

Cache design exploration in a general purpose massively parallel architecture
Memory model design is a major part of any modern processor architecture. There are many design choices and tradeoffs to be considered, and these often need to be tightly coupled to the processing unit's arcitecure. The increased popularity of massively parallel architectures has motivated …

Digital Sun Sensor Design for Nanosatellite Applications
In this research a novel, semi-custom design of a Sun sensor, based on the orthogonal photodiode array design approach, applicable for nanosatellites and other small spacecraft is proposed. A common and well-known strategy of application of a geometrical aperture mask on the light detectors is …

Turbulent mixing of unpremixed reactants in stirred tanks.
… technique and a bifurcated fiber optic probe of custom design. Measurements were taken at two axial-radial planes within the tank. In the reacting case, the second-order reaction between sodium hydroxide and hydrochloric acid was studied, and urinine acted as a fluorescent indicator which became …

Surface functionalisation techniques for colloidal inorganic nanocrystals
… and location of the silica shell. In Chapter 4, custom-synthesised amphiphilic polymers for water transfer and functionalisation of nanocrystals are synthesised, characterised and tested. Commercially-available polymers used for this purpose are examined, leading to a rationale for custom-design. …
