Taught Modules

EG-283 Mechanical Deformation in Structural Materials

Following on from the first year module "Mechanical Properties" this module provides further detail about the deformation characteristics of a wide range of engineering materials. The course aims to develop the understanding of topics taught in the first year module by application to high performance materials such as titanium and nickel. Further understanding of deformation and damage mechanisms is gained through targeted units on elasticity, plasticity, alloy strengthening, mechanics of materials, fatigue and creep. The knowledge provided then allows for topics such as methods of mechanical testing and additive layer manufacturing. The module then seeks to draw these topics together by considering application to three main material classes, metals, ceramics and composites.
GE-007 Foundation Physical and Environmental Geography

The module considers the impacts of physical geography processes on human habitation and how humans might mitigate against the effects of nature's extreme events. It also examines the complex issues surrounding human impacts on the landscape. Foundation Physical & Environmental Geography will pave the way for students to study Geography at Level 4 (Year 1). This module complements topics taught in the Foundation Human Geography module (GE-008), to give an understanding of physical geography and the environment.
GEG100 Geographical skills

The aim of this module is to introduce the participants to essential geographical skills. These invaluable skills will become enhanced throughout their degree at Swansea University. Participants should be able to apply these techniques in a wide variety of environments and contexts. Skills covered include essay writing, data analysis and map making
GEG277 Geographical Methods and Data Analysis

This core 20-credit module introduces a variety of physical and human geography methods, along with data analysis. The module builds upon student knowledge and covers research design, data collection and data analysis. Students are introduced to a range of lab and field techniques in physical and / or human geography along with statistical analysis. They gain experience in describing, interpreting and presenting the results.
GEG278 Dissertation Preparation Skills

This module builds upon student knowledge of social research methods and environmental methods (delivered in GEG277) through to the formulation of a dissertation proposal. The module focuses on key dissertation planning and preparation skills.
