Numerical Errors in a Familiar Technique: A Case Study of Polynomial Trend Surface Analysis

Autor: D. J. Unwin

Publikováno v: Geographical Analysis. 7:197-203

Prior to the widespread application of the digital computer, calculations in geography were seldom of an ambitious nature and at best involved the assistance of simple mechanical calculators. Errors resulting from the rounding of large and small numb

Spatial variations in the average rainfall-altitude relationship in Great Britain: an approach using geographically weighted regression

Autor: Chris Brunsdon, D. J. Unwin, John McClatchey

Publikováno v: International Journal of Climatology. 21:455-466

The relationship between annual rainfall totals and gauge elevation over Great Britain is re-examined using the recently developed technique of geographically weighted regression (GWR). This enables the spatial drift of regression parameters to be id

The fourier frequency-domain representation of sediment fabric anisotropy

Autor: E. Derbyshire, X. M. Fang, D. J. Unwin, M. Langford

Publikováno v: Computers & Geosciences. 18:63-73

The spatial characteristics of scanned images of sediment fabrics are analyzed and restructured using Fourier transformations. The resulting pictures are based on the frequency characteristics of the originals described as a series of sinusoidal wave

Generating and mapping population density surfaces within a geographical information system

Autor: M, Langford, D J, Unwin

Publikováno v: The Cartographic journal. 31(1)

Some alternative ways of presenting maps of spatial population distribution are examined using northern Leicestershire, England, as an example. The authors conclude that dasymetric and isarithmic maps are a desirable alternative and can be relatively

High-spin structures in127La and129La

Autor: P. J. Nolan, P J Smith, D J G Love, D J Unwin, P J Twin, D M Todd, A H Nelson, A. Kirwan

Publikováno v: Journal of Physics G: Nuclear Physics. 11:1271-1287

The odd-proton nuclei 127La and 129La have been investigated to high spin using gamma -ray spectroscopy. Seven new states have been found in 127La, while in 129La six new states were seen. In both nuclei, the yrast band has been extended to Jpi =47-/

Limitations of microcomputers in thematic mapping

Autor: D. J. Unwin, V. Gardiner

Publikováno v: Computers & Geosciences. 11:291-295

Hardware, software, and data requirements for thematic mapping are identified. Existing microcomputer-based systems are evaluated in terms of these requirements, with particular reference made to first-generation 8-bit machines. For some applications

A shape change along the yrast line in132Ce?

Autor: P J Twin, D J Unwin, D J G Love, A H Nelson, A. Kirwan, P. J. Nolan

Publikováno v: Journal of Physics G: Nuclear Physics. 11:L17-L20

A rotational band has been found in 132Ce which has a high moment of inertia. This band decays by a series of discrete transitions in the spin range (20-40) h(cross) and is more strongly populated above 26 h(cross) than the yrast band known previousl
