Thermodynamic design optimisation of an open recuperative twin-shaft solar thermal Brayton cycle with combined or exclusive reheating and intercooling by Meas, Matthew Robert

“…In this work, optimal design of three common open solar thermal Brayton cycle variants is investigated and compared using principles of the second law of thermodynamics and the method of entropy generation minimisation. …”

Trajectory Optimisation Inspired Design for Legged Robotics by Fisher, Callen

“…The results of the study revealed that the optimal method to accelerate was to launch straight into the desired gait (for both bipeds and quadrupeds), with a sliding mass template model emerging for all results. …”

Exploring the impact of novelty and objective-directed evolution in company with MAP-Elites and HyperNEAT by Breytenbach, Jeremy

“…MAP-Elites is referred to as an illumination algorithm because by retaining these elite agents in the population, we expect to increase the chances of exploring and thus illuminating novel, yet potentially high-performing regions of the search space. To evaluate these methods, we use Keep-away, a simulated collective robotics task within the RoboCup football framework as a case study. …”

Condition Monitoring of VSD-fed Induction Motors by Ralikalakala, Lebohang

“…A similar trend is observed in speed and torque pulsations of the motor under the respective faults. Similarly, the method of diagnostic variables has proven valid for both simulation and experimental results and is able to detect and localise inverter open switch fault for single and double switch fault. …”

Micro combined heat and power management for a residential system by Tichagwa, Anesu

“…A model of a residential μCHP system is formulated upon which these simulated tests are conducted. From these simulations, equations to model the costs of running a fuel-cell based μCHP system are proposed. …”

Leveraging the microbiome in host genome wide association studies by Awany, Denis

“…Philosophically, the non-parametric specification amounts to the addition of an infinite amount of prior information about all fine details of the parameters being modelled; thus represents an attractive strategy. The utility of the method is demonstrated through simulation experiments and application to real microbiome datasets for schizophrenia, HIV/AIDS, and atherosclerosis diseases, where it is shown that the method is not only robust but also has high statistical power for association inference, resulting in a framework that can contribute to our understanding of the link between the microbiome and human diseases. …”
