In this paper I discuss economic processes that may give rise to spatial patterns in data, and explore the relative merits of alternative modeling approaches when data are spatially correlated. Specifically, I present an estimation scheme that allows for spatial random effects, and focus attention on cases in which such a framework may be preferred to the more general fixed effects framework th...
Introduction: As the behavioral base of the family, the house is functionally and physically the place where the behavior, culture, and ethics of the community are formed. The traditional house of Iran has been a constructive and suitable place for this important. However, today's Iranian housing architecture is not a suitable container for this important because it has lost its Iranian charact...
Geometrical patterns are encountered in many different fields of science and technology, including porous media, biology, polymer chemistry, metallography, geology and astronomy. 1), 2) We characterize these patterns in terms of shape (geometry) and connectivity (topology) by means of morphological image analysis (MIA). This involves the calculation of the Minkowski functionals known from integ...
The origins of large-scale spatial patterns in biology have been an important source of theoretical speculation since the pioneering work by Turing (1952) on the chemical basis of morphogenesis. Knowing how these patterns emerge and their functional role is important to our understanding of the evolution of biocomplexity and the role played by self organization. However, so far, conclusive evid...
CWI's research has a theme-oriented structure and is grouped into four clusters. Listed below are the names of the clusters and in parentheses their acronyms. ABSTRACT We discuss issues arising when a spatial pattern is observed within some bounded region of space, and one wishes to predict the process outside of this region extrapolation as well as to perform inference on features of the patte...
Ecologists and conservation biologists have historically used species-area and distance-decay relationships as tools to predict the spatial distribution of biodiversity and the impact of habitat loss on biodiversity. These tools treat each species as evolutionarily equivalent, yet the importance of species' evolutionary history in their ecology and conservation is becoming increasingly evident....
introduction precipitation plays an important role in the global energy and water cycle. it is important for assessment and management of land use, agriculture and hydrology such as flood and drought risk reduction to know about the amount of precipitation reaching the ground water. assessment of climate change and its effects require long-term rainfall analysis in all spatial scales. growing c...
