Trees, B-series and G-symplectic methods

Autor: J. C. Butcher

Publikováno v: AIP Conference Proceedings.

The order conditions for Runge–Kutta methods are intimately connected with the graphs known as rooted trees. The conditions can be expressed in terms of Taylor expansions written as weighted sums of elementary differentials, that is as B-series. Po

Fatal equine meningoencephalitis in the United Kingdom caused by the panagrolaimid nematode Halicephalobus gingivalis: Case report and review of the literature

Autor: C. Hermosilla, J. Habershon-Butcher, S. Schöniger, K. M. Coumbe

Publikováno v: Equine Veterinary Journal. 43:759-763

A fatal case of eosinophilic and granulomatous meningoencephalitis caused by the free-living panagrolaimid nematode Halicephalobus gingivalis is reported in a 10-year-old Welsh gelding in the United Kingdom. Clinical examination first revealed behavi

Investigation of microbial keratitis: an audit from 1988-1992

Autor: A. B. Tullo, I. C. Lloyd, M. Armstrong, P. R. Simcock, J. M. Butcher

Publikováno v: Acta Ophthalmologica Scandinavica. 74:183-186

An audit was performed of the investigation of 263 cases of microbial keratitis severe enough to be admitted to the Manchester Royal Eye Hospital over the 5-year period, 1988-1992. A pathogen isolation rate of 37% was noted during the first year whic

Controlling clay pore pressures for cut-and-cover tunnelling

Autor: H. Roscoe, T. O. L. Roberts, D. J. E. Butcher, W. Powrie

Publikováno v: Proceedings of the Institution of Civil Engineers - Geotechnical Engineering. 160:227-236

To facilitate construction of the Channel Tunnel Rail Link through Ashford in cut-and-cover tunnels and retained cut, it was necessary to control pore water pressures in the relatively low-permeability, laminated Weald Clay. This was achieved by mean

Algebraic analysis of structure-preserving general linear methods

Autor: J. C. Butcher

Publikováno v: AIP Conference Proceedings.

G-symplectic general linear methods are capable of integrating Hamiltonian problems successfully if the parastitic growth factors are zero. This talk will attempt to explain this surprisingly good behaviour through a property known as cohesiveness. A
