Adaptive cruise control with collision-avoidance guarantees
An adaptive cruise control (ACC) is designed to schedule the velocity of a vehicle whilst maintaining an adequate distance to a vehicle in front. Subject to this distance requirement, the velocity control problem can show ...
Trans-barrier local magnetic actuation for robotics abdominal surgery
The advances in surgical instruments have played a significant role in the reduction of surgical trauma on patients. The evolution of surgical applications to the current popular approaches of minimally invasive surgery ...
Feedback-based iterative learning control for constrained systems with application to robotic manipulators
Iterative learning control (ILC) is an advanced control algorithm that achieves tracking of the desired reference trajectory through repetitions without using the precise knowledge of the dynamic systems. In a feed-forward ...
Techno-economic and environmental analysis of a hybrid power plant
This thesis presents a model to optimise the operation of a small-scale, grid-connected, hybrid power plant in deterministic and stochastic frameworks. The model minimises the total cost of supplying electricity from a ...
Characteristics of energetic motions in turbulent boundary layers
In this dissertation, we present the first measurements of two-dimensional (2-D) energy spectra of the streamwise velocity component (u) in high Reynolds number turbulent boundary layers. The measurements in the logarithmic ...
Wood particle based biocomposites consolidated by equal channel angular pressing
Previous research has demonstrated the potential of equal channel angular pressing (ECAP) for producing wood particle based biocomposites. By disturbing wood particle structure and reducing cellulose crystallinity, wood ...
Performance of electricity markets & power plant investments in the transition to a low-carbon power system
In power systems around the world, substantial quantities of Variable Renewable Generation (VRG) sources such as wind and solar are being introduced. Challenges arise from increasing VRG as it is characterised by significant ...
Experimental investigation of velocity and vorticity in turbulent wall flows
This thesis details the results of a research effort both to acquire sufficiently-resolved velocity and vorticity vector time-series in turbulent wall-bounded flows, as well as to use the acquired data to juxtapose two ...
Autoignition of pentane isomers in a spark-ignition engine: experiment & modeling uncertainty quantification
Pentane isomers are among the most abundant constituents of worldwide gasoline. Their autoignition has been extensively studied in fundamental reactors (shock tube, rapid compression machine (RCM), jet-stirred reactor, ...
Multimedia training facility for high speed machining
Change has now become a fact of life in all businesses, and training is no exception to the rule. (Leigh, 1996)
