A feasibility study for electron-muon correlations at ALICE by Nathanson, Nina

“…The e-μ channel would provide a much cleaner/low background signal than other currently-utilized probing methods, but it is statistics-limited, a re-striction which is of increased concern at ALICE due to the detector's geometry. …”

The role of concentrating solar power in a South African large scale renewable energy scenario by May, Haydn Liam

“…This thesis investigates a hypothetical large scale renewable energy system for South Africa over the long term future using 2050 as a nominal year of analysis. Simulation modeling was used to assess the integration of three renewable energy technologies, which are currently being installed at utility scales in South Africa, at much higher penetrations. …”

Navigating the Rules: Integrating TD3 and Sensor Fusion for Traffic-Aware Autonomous Vehicle Path Planning by Elsayed, Mahmoud Ayman Mohamed

“…This combined approach aims to overcome limitations associated with individual techniques, such as long training time for DRL and lack of generalizability of supervised learning methods. Results from the CARLA simulations demonstrated the effectiveness of the proposed method and sensor fusion in obstacle detection and navigation precision. …”

Efficient radio resource management for the fifth generation slice networks by Oladejo, Sunday Oladayo

“…Besides, neither stochastic geometry nor a three-level hierarchical business model schemes have been employed to model the global energy efficiency of the 5G slice network in the literature, making it the first time such method will be applied to 5G slice network. With rigorous numerical simulations based on Monte-Carlo numerical simulation technique, the performance of the proposed algorithms and schemes was evaluated to show their adaptability, efficiency and robustness for a 5G slice network.…”

Machine Learning for Radio Frequency Interference Flagging by Harrison, Kyle

“…This work explores the application of supervised machine learning algorithms for RFI flagging, trained on real measurement data and simulated data with simulated RFI. The goal of this work is to investigate the prediction of RFI using specific machine learning algorithms; Naive Bayes Classifier, K-Nearest Neighbours Classifier, Random Forest Classifier, the U-Net convolution neural network and the Multilayer Perceptron. …”
