Credit derivatives and sovereign debt
(CFAP, Cambridge Judge Business School, University of Cambridge, 2005-10)
We study the introduction of credit protection on sovereign debt. We find that such protection reduces debtor moral hazard by allowing a bonghokder to improve his position in negotiations with the sovereign. Moreover, ...
Ultra-fast Imaging of Two-Phase Flow in Structured Monolith Reactors; Techniques and Data Analysis
(University of CambridgeDepartment of Chemical Engineering, 2007-03)
This thesis will address the use of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) techniques to probe the “monolith reactor”, which consists of a structured catalyst over which reactions may occur. ...
Formulation of continuous/discontinuous Galerkin methods for strain gradient-dependent damage
(Strength Fracture and ComplexityStrength Fracture and Complexity, 2006)
Continuum damage models are widely used to represent the development of microscopic defects that coalesce into a macroscopic crack. The microscopic defects cause a progressive weakening or softening of the material (damage). ...
An interface element based on the partition of unity
(Delft University of Technology, 2001)
An alternative interface finite element is developed. By using the partition of unity property of finite element shape functions, discontinuous shape functions are added to the standard finite element basis. The interface ...
A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model: 2D results
(Proceedings of the 6th World Congress on Computational Mechanics in Conjunction with theputational Mechanics 2nd Asian-Pacific Congress on Computational MechanicsProceedings of the 6th World Congress on Computational Mechanics in Conjunction with theputational Mechanics 2nd Asian-Pacific Congress on Computational Mechanics, 2004)
The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models which involve gradients of the strain eld ...
A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model
(4th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS)4th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS), 2004)
The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models that involve gradients of the strain field ...
Automated modelling of viscoelastic flow using FEniCS
(XVI Convegno Italiano di Meccanica ComputazionaleXVI Convegno Italiano di Meccanica Computazionale, 2006)
Using high-level abstractions, it is possible to efficiently automate the development of finite element models. This has advantages in terms of rapid development, a dramatic reduction in programming errors and offers the ...
A study of discontinuous Galerkin methods for thin bending problems
(Computational Mechanics: Solids Structures and Coupled ProblemsComputational Mechanics: Solids Structures and Coupled Problems, 2006)
Various continuous/discontinuous Galerkin formulations are examined for the analysis of thin plates. These methods rely on weak imposition of continuity of the normal slope across element boundaries. We draw here upon ...
A $C^0$ discontinuous Galerkin formulation for thin shells
(2007)
This paper presents a C 0 discontinuous Galerkin formulation for the simulation of thin shells. The method is based on Koiter’s shell model and allows finite element solutions to be obtained by using standard $C^0$ Lagrange ...
Model-based approaches to support process improvement in complex product development
(University of CambridgeDepartment of Engineering, 2007-10-23)
The performance of product development processes is important to the commercial success of new products. The improvement of these processes is thus a strategic imperative for many engineering companies — the aero-engine ...
