EG-2004 AI, Machine Learning and Data Analysis
This module provides an introduction to several AI algorithms for engineering/physics problems. The specific engineering problems chosen to demonstrate the benefits offered by AI algorithms are 1) interpretation/processing of data from distributed sensors; 2) optimisation of material/device properties through physics informed neural network. The module teaches students basic statistical skills underpinning machine learning/artificial intelligence such as probability analysis and regression, as well as several case studies that use existing AI software to analyse engineering problems. Two assessments (exam and individual project, each carries 50%) for each term, designed to examine understanding of the basic machine leaning concepts and using the software to solve engineering problems, take place in the middle of term and end of term. Emphasis is placed on the use of existing software for tackling engineering problems.

EG-2038 Microstructure Evolution and Control in Metallic Materials: Theory and Practicals
This module introduces the fundamental principles of thermodynamics and kinetics that underpin the development and interpretation of phase diagrams, key phase transformations, and the resulting evolution of microstructure in metallic materials. It examines how microstructures develop and how they can be controlled to tailor the mechanical properties of metallic alloys, with a focus on industrially significant manufacturing processes and commercially important alloy systems. A wide range of case studies is integrated throughout the module to illustrate real-world applications and enhance contextual understanding. Theoretical concepts are reinforced through practical components, enabling students to examine, measure, and interpret microstructure formation and associated mechanical properties across various commercial alloys. The module also develops skills in microstructural and mechanical property characterisation, and fosters logical reasoning based on binary phase diagrams to understand phase transformations and the influence of processing on microstructure. Mae¿r modiwl hwn yn cyflwyno egwyddorion sylfaenol thermodynameg a chineteg sy¿n sail i ddatblygu a dehongli diagramau cam, trawsnewidiadau cam allweddol, a¿r esblygiad o strwythurau micro mewn deunyddiau metelig. Mae¿n archwilio sut mae strwythurau micro yn datblygu a sut y gellir eu rheoli i addasu priodweddau mecanyddol aloion metelig, gan ganolbwyntio ar brosesau gweithgynhyrchu o bwys diwydiannol ac ar systemau aloion masnachol arwyddocaol.
