Two-pass decision tree construction for unsupervised adaptation of HMM-based synthesis models
(2009)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 ...

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. ...

Development and validation of a combustion model for a fuel cell off-gas burner
(University of CambridgeMagdalene College, 2008-10-14)A low-emissions power generator comprising a solid oxide fuel cell coupled to a gas turbine has been developed by Rolls-Royce Fuel Cell Systems. As part of the cycle, a fraction of the unreacted fuel (the off-gas) and ...

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 ...

Development of novel laser diagnostic techniques for the quantitative study of premixed flames
(University of CambridgeJesus College, 2009)The main topic of this thesis concerns the development and application of laser diagnostic techniques for accurate temperature measurements and for the determination of flamefront properties in premixed flames that can ...

On strategic default and liquidity risk
(CFAP, Cambridge Judge Business School, University of Cambridge, 2002)How does the uncertain provision of external finance affect investment projects' default probability and liquidity risk? In this paper, I study the strategic interaction between many creditors and a single borrower in the ...

The supervisory approach: a critique
(CFAP, Cambridge Judge Business School, University of Cambridge, 2002)Rules suffer from two serious defects. The world is complex, and so the creation and application of rules is difficult; and it changes, so that rules become obsolete. In recent years, the conventional wisdom on financial ...

Depreciation bias, financial-sector fragility and currency risk
(CFAP, Cambridge Judge Business School, University of Cambridge, 2002)Do expected future exchange rate fluctuations affect current social welfare? In the third-generation approach to currency crises, financial fragility can trigger devaluation and default. Expected future depreciation is ...

Establishing a European securities regulator: is the European Union an optimal economic area for a single securities regulator?
(CFAP, Cambridge Judge Business School, University of Cambridge, 2002)The paper’s purpose is to address the economic, institutional, and legal issues confronting the establishment of a more centralised approach to EU securities regulation and to suggest that the theory of optimum currency ...

The World Trade Organization and financial stability: the balance between liberalisation and regulation in the GATs
(CFAP, Cambridge Judge Business School, University of Cambridge, 2003)The WTO General Agreement on Trade in Services and its Annex on Financial Services provide the international legal framework for the regulation of cross-border trade in financial services. This paper analyses some of the ...

The new Basel accord and developing countries: problems and alternatives
(CFAP, Cambridge Judge Business School, University of Cambridge, 2002)The new Basel Accord framework relies on markets and supervisors to discipline banks. Yet both markets and supervisors fail, and more so in developing countries than in high-income countries. Therefore, the new Accord is ...
