Thomas C. Schelling showed that global aggregation may occur, even if it does not correspond to agent preferences; thus, to some extent his model supported the view that segregation is unavoidable, whatever the tolerance is. The segregation landscape approach proposed in this paper is seriously weakening this hypothesis; here, we radically change the perspective and propose using the landscape ...

what to look for in abbas abad pool? a lake in middle of the forest on the mountain heights with an encircled building with waters and a garden ashore? why are the trees cut and used to build a garden? and what is the purpose of placing a lake on a dominant and deep valley over the khazar sea. today, green trees are grown in abbas abad garden and no sign of landscaping or water features can be ...

A seed shadow is the spatial pattern of seed distribution relative to parent trees and other conspecifics; it results from the process of seed dispersal and represents the starting template for plant regeneration. Janzen (1970) and Connell (1971) consider it the population recruitment surface. For animal-dispersed, endozoochorous species the seed shadow results primarily from movement patterns ...

A detailed analysis of homogeneous melting in crystalline materials modeled by empirical interatomic potentials is presented using the theory of inherent structures. We show that the homogeneous melting of a perfect, infinite crystalline material can be inferred directly from the growth exponent of the inherent structure density-of-states distribution expressed as a function of formation enthal...

The application of information technology to landscape analysis dates back to the early work in computer-based mapping. Indeed, much of the early development of what became geographic information systems (GIS) and three-dimensional landscape simulation was undertaken by landscape architects. Mapping of viewsheds quickly became a key element of the landscape-planning process. The process was app...

without the surrounding environment of a site, architecture loses its full meaning. in the evolutionof the design process, a site's environment should be understood as the integral factor within which a designed productor artifact is expected to perform. the environment is not of secondary priority. every building is intertwined with itscontext; context being its physical, visual and ecological...

We uncovered the underlying energy landscape for a cellular network. We discovered that the energy landscape of the yeast cell-cycle network is funneled towards the global minimum (G0/G1 phase) from the experimentally measured or inferred inherent chemical reaction rates. The funneled landscape is quite robust against random perturbations. This naturally explains robustness from a physical poin...
