1. Knotted Nodal Band Structures
Abstract : It is well known that in conventional three dimensional (3D) Hermitian two band models, the intersections between the energy bands are generically given by points. The typical example are Weyl semimetals, where these singular points can be effectively described as Weyl fermions in the low energy regime. READ MORE

2. The Construction of the Professional Identity of the TV News Presenter in Two Chinese News Programmes : A Discourse-Theoretical Analysis
Abstract : This PhD research project investigates how the professional identity of the Chinese TV news presenter is constructed in two news programmes, Guangdong News and TVS News, both based at Guangdong TV. The overarching theoretical framework of the project takes its inspiration from Laclau and Mouffe's (1985) post-structuralist discourse theory (DT). READ MORE

3. Predictors of Lymph Node Metastasis in Primary Breast Cancer - Risk Models for Tailored Axillary Management
Abstract : Most patients with breast cancer present with low-risk tumors, node-negative disease, and excellent prognosis. For these patients, routine axillary nodal staging by sentinel lymph node biopsy (SLNB) has no therapeutic benefit. For patients with limited sentinel lymph node metastasis, completion axillary nodal dissection is controversial. READ MORE

4. Simulation of Delamination Initiation and Growth in Fiber Composite Laminates
Abstract : This thesis concerns the topic of delaminations in unidirectional fiber reinforced plastic composite laminates.A model for the simulation of delamination initiation and growth has been developed. It is based on fracture mechanics and formulated as a combination of a cohesive zone model and a linear elastic adhesive penalty formulation. READ MORE

5. Co-rotational beam elements in instability problems
Abstract : The purpose of the work presented in this thesis is to implement co-rotational beam elements and branch-switching procedures in order to analyse elastic and elastoplasticinstability problems. For the 2D beam elements, the co-rotational framework is taken from Crisfield [23]. READ MORE
