The generalized entropy, calculated from the quadrat counts of the population of the United States and Great Britain, is plotted against the logarithm of the quadrat size. These graphs are linear over a range of scales that corresponds to the size

Simultaneous optimization of land use and transportation. A synthesis of the quadratic assignment problem and the optimal network problem in Quadratic models of spatial allocation.

La même structure de points est analysée avec des quadrats de différentes tailles. Les aspects de la théorie de l'information pertinents pour la méthode des quadrats| description des résultats reliant le comportement de l'indice de redondance au

A study of multipurpose shopping at a range of planned suburban shopping centres in Sydney during 1988/89 endeavour to relate several hypotheses to results from a space-time differential consumer-trip model. The number of consumers is shown to form
a substantial quadratic relationship with centre scale. The model predicts positive and negative states of MPS. Distinctly different socioeconomic groups can have in common a MPS strategy independent of centre scale. They are using this strategy as a mechanism

Les mesures en lichenométrie ne pouvant être aisément reproduites, les observateurs obtiennent des résultats plus cohérents par la répétition d'une recherche sur quadrat.

Use of the linear quadratic approach to study the dynamic policy responses of a non linear model of the French economy

Three different drainage basins were studied with the aid of a quadratic grid consisting of 3439 data points. For each areal unit (4 km) the relative height was calculated as the difference between the highest and the lowest point
then gradually, and disappearing entirely at some pint in the range 30-80 m depending on the area concerned. The figures of 30 m and 80 m emerged as two of the most appropriate boundary values for a relative height classification suitable for Northern Finland

This paper records 1) the impact of a wildfire on permanent quadrats established along a moisture gradient in a subcoastal wet monsoon rainforest and 2) the impact of a tropical cyclone on permanent quadrats established across a boundary between dry

An algorithm for the solution of a quadratic programming problem, with application to constrained matrix and spatial price equilibrium problems

An optimal quadratic equilibrium model based on Israel's multiregional input-output tables

Analysis of a distribution of point events using the network-based quadrat method

Convexity and duality properties of a quadratic intraregional location model in Quadratic models of spatial allocation.

in southwestern Oklahoma, USA. Nearest neighbor and quadrat analyses are used for describing settlement morphologies that, with time, exhibited clustering tendencies. Dwellings comprising the contemporary settlement occupied sites that indicated rural inhabitants

Economics of information examples in location and land use theory in Quadratic models of spatial allocation.

A regional planning model and its application to southeastern Australia in Quadratic models of spatial allocation.

Présentation d'approches théoriques et algorithmiques pour effectuer une analyse d'aggrégation de quadrats à partir d'une densité donnée. Ceux-ci sont traités comme des régions multifractales dont la dimension fractale varie selon l'intensité
