abstract urban neighborhoods are as the smallest unit of spatial organization in the city to urban stability. neighborhoods development will be considered one of the main goals of planning the urban stability development and, it is key action to achieve stable development. stable community development perspective, will strengthen the new approach, that the solving of the urban problems is perce...

the minimal prime decomposition for semiprime ideals is defined and studied on z-ideals of c(x). the necessary and sufficient condition for existence of the minimal prime decomposition of a z-ideal / is given, when / satisfies one of the following conditions: (i) / is an intersection of maximal ideals. (ii) i is an intersection of o , s, when x is basically disconnected. (iii) i=o , when x x ha...

following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. however, this concept has originally been developed for american and european neighborhoods’ planning, it could also be customized for other neighborhoods’. additionally, in the neighborhood scale, the quality parameter f...

BACKGROUND Identifying neighborhood environment attributes related to childhood obesity can inform environmental changes for obesity prevention. PURPOSE To evaluate child and parent weight status across neighborhoods in King County (Seattle metropolitan area) and San Diego County differing in GIS-defined physical activity environment (PAE) and nutrition environment (NE) characteristics. MET...

We consider neighborhood search defined on combinatorial optimization problems. Suppose that N is a Neighborhood for combinatorial optimization problem X. We say that N′ is LO-equivalent (locally optimal) to N if for any instance of X, the set of locally optimal solutions with respect to N and N′ are the same. The union of two LO-equivalent neighborhoods is itself LO-equivalent to the neighborh...

Urban scholars have made great advances to understand the reciprocal relations between households and their immediate environments as a means for creation of efficient urban administrative systems. However, from an management perspective, reliance on geographical areas fixed long periods time basic data collection constitutes problem. Modern are in permanent state flux because changing preferen...

neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. traditional neighborhoods of iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. in the modern era, the new master plans and the complementary local plans have disintegrated these...
