urban green spaces and parks are important land use of cities which promote quality of life by providing facilities for leisure and also play a crucial role in social cohesion and participation due to their socio-economic and environmental functions. hence the distribution of such spaces is very important in cities. however the zone of 3 in tehran has a relative appropriate green space per capi...

Consider 1D Vlasov-poisson system with a …xed ion background and periodic condition on the space variable. First, we show that for general homogeneous equilibria, within any small neighborhood in the Sobolev space W s;p p > 1; s < 1 + 1 p of the steady distribution function, there exist nontrivial travelling wave solutions (BGK waves) with arbitrary minimal period and traveling speed. This impl...

conclusions the findings point to a relationship between neighborhood characteristics and obesity only in the azeri turks. however, educational level was more important than neighborhood quality in predicting the risk of obesity results three common neighborhood environments were identified: 1) modern-affluent, 2) central-high access and 3) marginal. these three factors explained 73.2% of the t...

Neighborhood filters are image and movie filters which reduce the noise by averaging similar pixels. The object of the paper is to present a unified theory of these filters and reliable criteria to compare them to other classes of filters. First a CCD noise model will be presented justifying this class of algorithm. A classification of neighborhood filters is proposed, including classical image...

Granular Computing on partitions (RST), coverings (GrCC) and neighborhood systems (LNS) are examined: 1. The order of generality is RST, GrCC, and then LNS 2. The quotient structure: In RST, it is called quotient set. In GrCC, it is a simplical complex, called the nerve of the covering in combinatorial topology. For LNS, the structure has no known description. 3. The approximation space of RST ...

In this paper, new definitions of $L$-fuzzy closure operator, $L$-fuzzy interior operator, $L$-fuzzy remote neighborhood system, $L$-fuzzy neighborhood system and $L$-fuzzy quasi-coincident neighborhood system are proposed. It is proved that the category of $L$-fuzzy closure spaces, the category of $L$-fuzzy interior spaces, the category of $L$-fuzzy remote neighborhood spaces, the category of ...

The positive relationships between urban green space and health have been well documented. Little is known, however, about the role of residents' emotional attachment to local green spaces in these relationships, and how attachment to green spaces and health may be promoted by the availability of accessible and usable green spaces. The present research aimed to examine the links between self-re...
