Cox, S.J., Daniell, G.J., Nicole, D.A.

By picking unpopular sets of numbers in a lottery, it is possible to increase one’s expected winnings. We have used the Maximum Entropy method to estimate the probability of each of the 14 million...

Effective Medium Theory of Light Scattering in PDLC films (1998)

COX, S.J., SLUCKIN, T.J., RESHETNYAK, V.Yu.

We present calculations of the optical properties of PDLC films subjected to normally incident unpolarized light, in the long-wavelength regime under which the Rayleigh–Gans approximation applies....

Theory of Dielectric and Optical Properties of PDLC films (1998)

COX, S.J., SLUCKIN, T.J., RESHETNYAK, V.Yu.

We present results of the light scattering properties of PDLC films in the Rayleigh-Gans long wavelength régime. The calculations take into account dependent scattering effects using an effective...

Using Maximum Entropy to Double One's Expected Winnings in the UK National Lottery 1998 (1998)

Cox, S.J., Daniell, G.J., Nicole, D.A.

We have used the Maximum Entropy method to estimate the probability of each of the 14 million tickets being chosen by players in the UK National Lottery. As data, we used the numbers of winners in...

Commodity High Performance Computing at Commodity Prices (1998)

Cox, S.J., Nicole, D.A., Takeda, K.

Effective Medium Theory of Polymer Dispersed Liquid Crystal Droplet Systems II: Partially Oriented Bipolar Droplets (1997)

RESHETNYAK, V.Yu., SLUCKIN, T.J., COX, S.J.

We construct a theory of the dielectric properties of a polymer dispersed liquid crystal droplet film containing bipolar droplets whose principal axes respond to an electric field. The theory...

Latest JET results in deuterium and deuterium-tritium plasmas (1997)

Adams, J. M., Ageladarakis, P., Arshad, S. A., Alper, B., Altmann, H., Andrew, P., ...

All major JET systems have been fully commissioned for D-T and the DTE1 series of experiments has started with the D-T fuel mixture and operating conditions foreseen for ITER. In the area of ITER...

Effective Medium Theory of Polymer Dispersed Liquid Crystal Droplet Systems I: Spherical Droplets (1996)

RESHETNYAK, V.Yu., SLUCKIN, T.J., COX, S.J.

We introduce an effective-medium theory for the local field and mean dielectric function of a polymer dispersed liquid crystal (PDLC) film consisting of identical spherical liquid crystal droplets...

Scale Based Features For Audiovisual Speech Recognition (1996)

I.A. Matthews, J.A. Bangham, S.J. Cox

This paper demonstrates the use of nonlinear image decomposition, in the form of a sieve, applied to the task of audiovisual speech recognition of a database of the letters A--Z for ten talkers. A...

Spontaneous external biliary fistula uncomplicated by gallstones.

Birch, B. R., Cox, S. J.

External biliary fistulae are rare. Only 65 cases have been reported in the literature and in each instance gallstones were a complicating factor. We report in this paper the first case of...

Modelling studies to estimate the prevalence of foot-and-mouth disease carriers after reactive vaccination

Arnold, M.E, Paton, D.J, Ryan, E, Cox, S.J, Wilesmith, J.W

Foot-and-mouth disease (FMD) is a highly contagious and economically significant viral disease of cloven-hoofed animals. Vaccination can be used to help restrict the spread of the infection, but...
