Reduced Temperature Return-to-Power Demonstration
Autor: M. Plumier, C. E. Meyer, N. P. Mueller, R. Leroy, M. G. Watts, C. J. Saint-Mard
Publikováno v: Nuclear Technology. 59:14-19
A demonstration of reduced temperature return-to-power was performed at the 920-gross-MW(electric) Tihange nuclear station in Belgium. A rapid power escalation of 320-MW(electric) in gross output was achieved using control rod withdrawal and moderato

The end-point distribution of self-avoiding walks on a crystal lattice. II. Loose-packed lattices
Autor: M G Watts
Publikováno v: Journal of Physics A: Mathematical, Nuclear and General. 7:489-494
A study is made of the mean-square lengths of self-avoiding walks on a number of loose-packed lattices. It is found that the even-odd oscillations characteristic of this type of lattice may be largely removed by the use of an Euler transformation. Fr

Publikováno v: Journal of Physics A: Mathematical and General. 8:1461-1468
For pt.VIII see ibid., vol.8, no.9, p.1448 of 1975. The derivation of high-field expansions for the honeycomb and triangular lattices is described briefly. New results are given for the high-field polynomials L11 and L12 on the triangular lattice and

High-temperature spontaneous magnetization of models with pure triplet interactions
Autor: I G Enting, M G Watts
Publikováno v: Journal of Physics A: Mathematical and General. 8:L39-L42
A configurational proof is given that at high enough temperatures the triplet model on the triangular lattice has zero spontaneous magnetization. On the face-centred cubic lattice the spontaneous magnetization is shown to be nonzero for all finite te

Magnetization of the three-spin triangular Ising model
Autor: M G Watts, M F Sykes, R J Baxter
Publikováno v: Journal of Physics A: Mathematical and General. 8:245-251
Below its critical temperature, the triangular Ising model with pure three-spin interactions has a spontaneous magnetization M. The first 13 terms of a series expansion for M are known. Here these are re-arranged into a form which can be extrapolated

Derivation of low-temperature expansions for Ising model. VII. The honeycomb-triangular code system

Publikováno v: Journal of Physics A: Mathematical and General. 8:1441-1447
For pt.VI see abstr. A72435 of 1973. It is shown how the principle of complete code balance can be exploited in a systematic way and the method is generalized to apply to partial codes. Euler's law of the edges is used to establish a latent symmetry

Critical indices for an Ising model with pure triplet interactions on the triangular lattice
Autor: M G Watts
Publikováno v: Journal of Physics A: Mathematical, Nuclear and General. 7:L85-L88
Extended series for the spontaneous magnetization and reduced susceptibility of the triplet model on the triangular lattice are analysed using Pade approximants. Baxter and Wu's exact solution (1973) for the specific heat has been used as a guide in

Application of the method of Pade approximants to the excluded volume problem
Autor: M G Watts
Publikováno v: Journal of Physics A: Mathematical and General. 8:61-66
Pade approximants have been applied to the analysis of the chain generating functions of all the common two- and three-dimensional lattices. Estimates for the critical attrition mu , are in very close agreement with those obtained using the ratio met

The end-point distribution of self-avoiding walks on a crystal lattice
Autor: M G Watts, J L Martin
Publikováno v: Journal of Physics A: General Physics. 4:456-463
A recursive relation connecting the numbers of self-avoiding walks on an arbitrary network with the numbers of certain related topologies is given, and is used to obtain exact end-point distributions of self-avoiding walks on a variety of Bravais lat
