Geometric properties of streamlines in turbulent wall-flows
Streamline geometry has been studied in case of turbulent wall flows. Complex but coherent motions form and rapidly evolve within wall-bounded turbulent flows. Research over the past two decades broadly indicates that the ...
Methods for profling heterogeneous sequencing data
Metagenomics which utilises high throughput DNA sequencing is widely applied to study bacteria and viruses and their effects on their host environments. Metagenomics involves collective sequencing of genetic material of ...
Robust Object Manipulation for Fully-Actuated Robotic Hands
Object manipulation is the ability to rotate/translate an object held within a grasp. Humans have exploited this ability to effectively use tools and interact with the environment. Over the past decades, robotics research ...
Dynamic decision making within spatially-explicit systems subject to environmental uncertainty
Dynamic decision making under uncertainty provides managers with tools to make better-informed decisions to improve objectives such as profits, throughput through networks, scheduling, and reducing the impact of extreme ...
Sensor and actuator selection for feedback control of fluid flows
The present thesis regards linear estimation and control for two fluid flows, with a particular focus on the placement of sensors and actuators. In the first part of the thesis, we study the complex Ginzburg-Landau equation, ...
Robust predictive control of diesel airpath
In an automotive diesel airpath application, the controller is required to track reference values of intake manifold (boost) pressure and exhaust gas recirculation (EGR) rate. EGR rate is the ratio of the EGR outflow rate ...
Reduced-order modeling for membrane wings at low Reynolds numbers
The present work develops reduced-order models for the fluid-structure interaction of two-dimensional membrane wings at low Reynolds numbers. The fluid-structure interaction models are obtained from the coupling between a ...
Underground mine plan optimisation
This thesis addresses several topics relating to the planning of underground mines, with a focus on underlying mathematical models. Some mineral resources are mined by a combination of open-pit and underground mining ...
An experimental study of flame-wall Interaction and exhaust CO emissions
This thesis reports on flame-wall interaction (FWI) and flame-cooling-air interaction (FCAI), and shows that they can directly impact exhaust CO emission ([CO]_exh). These conclusions are determined through the application ...
Methods for modeling advertising channel sequences in an online environment
In today’s age of rapid technological advancement, there is an extensive choice of advertising channels available to marketing practitioners. From traditional offline channels to burgeoning online channels, the options and ...
