چکیده

In a previous paper (Figueiredo and Amorim, 2005), we introduced the continuity lines, a compressed description that encapsulates topological and geometrical properties of urban grids. In this paper, we applied this technique to a large database of maps that included cities of 22 countries. We explore how this representation encodes into networks universal features of urban grids and, at the same time, retrieves differences that reflect classes of cities. Then, we propose an emergent taxonomy for urban grids.

URBAN SHAPES AND URBAN GRIDS : a comparative study of Adriatic and Ionian coastal cities 009

This paper models in a precise quantitative manner the proposition that the properties of urban shapes strongly and significantly affect the syntactic properties of urban grids. Urban shapes are described according to three measures of shape compactness and fragmentation and their skewness of distribution. The analysis of a large sample of coastal cities has shown that urban shapes affect the i...

Optimal Self-healing of Smart Distribution Grids Based on Spanning Trees to Improve System Reliability

In this paper, a self-healing approach for smart distribution network is presented based on Graph theory and cut sets. In the proposed Graph theory based approach, the upstream grid and all the existing microgrids are modeled as a common node after fault occurrence. Thereafter, the maneuvering lines which are in the cut sets are selected as the recovery path for alternatives networks by making ...

Global Health Politics: Neither Solidarity nor Policy; Comment on “Globalization and the Diffusion of Ideas: Why We Should Acknowledge the Roots of Mainstream Ideas in Global Health”

The global health agenda has been dominating the current global health policy debate. Furthermore, it has compelled countries to embrace strategies for tackling health inequalities in a wide range of public health areas. The article by Robert and colleagues highlights that although globalization has increased opportunities to share and spread ideas, there is still great asymmetry of power accor...

Spatially Periodic Cells Are Neither Formed From Grids Nor Poor Isolation

Grid cells recorded in the parahippocampal formation of freely moving rodents provide a strikingly periodic representation of self-location whose underlying mechanism has been the subject of intense interest. Our previous work(1) showed that grid cells represent the most stable subset of a larger continuum of spatially periodic cells (SPCs) which deviate from the hexagonal symmetry observed in ...
