Do Disaster Expectations Explain Household Portfolios?
(CFAP, Cambridge Judge Business School, University of Cambridge, 2010-03)It has been argued that rare economic disasters can explain most asset pricing puzzles. If this is the case, perceived risk associated with a disaster in stock markets should be revealed in household portfolios. That is, ...

Experimental investigations into high-altitude relight of a gas turbine
(University of CambridgeDepartment of Engineering, 2008-11-18)This thesis describes experiments to investigate high-altitude relight of a lean direct injection (LDI) combustor. The features that make LDI technology less polluting in terms of NOx compared to conventional combustors ...

From Trade-to-Trade in US Treasuries
(CFAP, Cambridge Judge Business School, University of Cambridge, 2010-05)The aim of this paper is to model the trading intensity of the US Treasury bond market which has a unique expandable limit order book which distinguishes its structure from other asset markets. An analysis of tick data ...

Selective cation-exchange adsorption of the two major whey proteins
(University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2010-03-16)Whey is a by-product of cheese manufacture, containing a mixture of proteins of commercial value, each having unique attributes for nutritional, biological and food ingredient applications. A tremendous amount of whey, ...

Engineering Fundamentals of Energy Efficiency
(University of CambridgeDepartment of Engineering, 2010-03-16)Using energy more efficiently is essential if carbon emissions are to be reduced. According to the International Energy Agency (IEA), energy efficiency improvements represent the largest and least costly savings in carbon ...

Tomographic PIV measurement of coherent dissipation scale structures
(University of CambridgeDepartment of Engineering, 2010-05-04)Further understanding the small scale coherent structures which occur in high Reynolds number turbulence would be of enormous benefit. Therefore, the aim of the current project was to make well resolved three-dimensional ...

Rainfall trends in India and their impact on soil erosion and land management
(University of CambridgeDepartment of Engineering, 2010-02-09)Under the threat of global warming it is vital to determine the impact that future changes in climate may have on the environment and to what extent any adverse effects can be mitigated. In this research an assessment was ...

Scalar dissipation rate based flamelet modelling of turbulent premixed flames
(University of CambridgeDepartment of EngineeringTrinity Hall, 2010-03-16)Lean premixed combustion has potential for reducing emissions from combustion devices without compromising fuel efficiency, but it is prone to instabilities which presents design difficulties. From emissions point of view ...

Feedback control of oscillations in combustion and cavity flows
(University of CambridgeDepartment of Engineering, 2010-02-09)This thesis considers the control of combustion oscillations, motivated by the susceptibility of lean premixed combustion to such oscillations, and the long and expensive development and commissioning times that this is ...

The Development of a Set of Principles for Through-Life Management of Engineering Information
(Engineering Design Centre, Department of Engineering, University of Cambridge, 2009-10-26)Corporate business models are shifting away from product delivery paradigms to product-service paradigms, where ongoing through-life service support is preeminent. In the UK, a Grand Challenge project (www.kimproject.org) ...

Optimisations for quadrature representations of finite element tensors through automated code generation
(ACM Transactions on Mathematical Software, 2010)We examine aspects of the computation of finite element matrices and vectors which are made possible by automated code generation. Given a variational form in a syntax which resembles standard mathematical notation, the ...
