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, ...
The production of pure hydrogen with simultaneous capture of carbon dioxide
(University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2010-10-12)
The need to stabilise or even reduce the production of anthropogenic CO2 makes the capture of CO2 during energy generation from carbonaceous fuels, e.g. coal or biomass, necessary for the future. For hydrogen, an ...
Unsupervised intralingual and cross-lingual speaker adaptation for HMM-based speech synthesis using two-pass decision tree construction
(IEEE Transactions on Audio, Speech and Language Processing, 2010)
Hidden Markov model (HMM)-based speech synthesis systems possess several advantages over concatenative synthesis systems. One such advantage is the relative ease with which HMM-based systems are adapted to speakers not ...
Direct numerical simulations of spray spark ignition
(Engineering Department, 2010-09-09)
Direct Numerical Simulations (DNS) of a mono-disperse spray in a turbulent flow have been used to explore the nature of flame kernels when a spark is deposited in the spray. The simulations use complicated chemistry and ...
Unsupervised cross-lingual speaker adaptation for HMM-based speech synthesis using two-pass decision tree construction
(Proceedings of the IEEE International Conference on Acoustics, Speech and Signal ProcessingProceedings of the IEEE International Conference on Acoustics, Speech and Signal Processing, 2010)
This paper demonstrates how unsupervised cross-lingual adaptation of HMM-based speech synthesis models may be performed without explicit knowledge of the adaptation data
language. A two-pass decision tree construction ...
Autoignition of droplets in hot air flow
(2010-09-09)
A single-droplet generator has been used to inject fuel droplets of various sizes and chemical composition into a hot turbulent air flow. The ensuing autoignition and flame behaviour has been recorded with a fast camera. ...
Autoregressive clustering for HMM speech synthesis
(ISCA (International Speech Communication Association)Proceedings of the 11th Annual Conference of the International Speech CommunicationProceedings of the 11th Annual Conference of the International Speech Communication, 2011)
The autoregressive HMM has been shown to provide efficient parameter estimation and high-quality synthesis, but in previous experiments decision trees derived from a non-autoregressive system were used.
In this paper we ...
Thin-walled composite deployable booms with tape-spring hinges
(University of CambridgeDepartment of EngineeringWolfson College, 2011-07-12)
Deployable structures made from ultra-thin composite materials can
be folded elastically and are able to self-deploy by releasing the
stored strain energy. Their lightness, low cost due to smaller
number of components, ...
Acoustics and manufacture of Caribbean steelpans
(University of CambridgeDepartment of EngineeringWolfson CollegeInstitute for Manufacturing, 2011-03-15)
The Caribbean steelpan is a pitched percussion instrument that originated in Trinidad and Tobago
during the Second World War. Despite several research initiatives to improve the making of this
relatively new instrument, ...
Social network support for data delivery infrastructures
(University of CambridgeFaculty of Computer Science and TechnologyComputer Laboratory, 2011-10-11)
Network infrastructures often need to stage content so that it is accessible to consumers. The standard solution, deploying the content on a centralised server, can be inadequate in several situations.
Our thesis is ...
