Modelling Spatial Regimes in Farms Technologies [PDF]

open access: yes, 2017
We exploit the information derived from geographical coordinates to endogenously identify spatial regimes in technologies that are the result of a variety of complex, dynamic interactions among site-specific environmental variables and farmer decision ...

Supporting Device Discovery and Spontaneous Interaction with Spatial References [PDF]

open access: yes, 2008
The RELATE interaction model is designed to support spontaneous interaction of mobile users with devices and services in their environment. The model is based on spatial references that capture the spatial relationship of a user’s device with other co ...

Spatial Stimuli Gradient Sketch Model

open access: yes, 2015
The inability of automated edge detection methods inspired from primal sketch models to accurately calculate object edges under the influence of pixel noise is an open problem. Extending the principles of image perception i.e.

Modelling Spatial Patterns

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1977
Summary Spatial point processes may be analysed at two levels. Quadrat and distance methods were designed for the sampling of a population in the field. In this paper we consider those situations in which a map of a spatial pattern has been produced at some cost and we wish to extract the maximum possible information.

Provincial town as a spatial model in the satirical and humorous literature

open access: yesСемиотические исследования, 2023
The article deals with the artistic functions of local spatial models in the Russian satirical and humorous prose of the 20th century. It gives an idea of the typology of comic evaluation objects (character, situation, event, space). Particular attention
