It is shown that a topographic product P, first introduced in nonlinear dynamics, is an appropriate measure of the preservation or violation of neighborhood relations. It is sensitive to large-scale violations of the neighborhood ordering, but does not account for neighborhood ordering distortions caused by varying areal magnification factors. A vanishing value of the topographic product indica...

sports spaces are the most important services in the city, that have a significant role in raising physical and mental health citizens. after studying the existing sports spaces in the neighborhood, district, region and city of zanjan, determined levels and percapita sport spaces of zanjan city. a total of 19 spaces sports zanjan city, 9 sport spaces neighborhood-scale, 6 sport spaces district ...

ـــــ In [25], we introduce the notion of r-fuzzy neighborhood filters in smooth topological spaces in sense of Gähler [10], and used it to define and study separation axioms , = , , . Here we continue our study of the axioms of separation in smooth topological spaces. Therefore, we introduce the notion of r-fuzzy neighborhood filter at a set. Then by using this notion we define and study separ...

The Bisognano-Wichmann property on the geometric behavior of the modular group of the von Neumann algebras of local observables associated to wedge regions in Quantum Field Theory is shown to provide an intrinsic suucient criterion for the existence of a covariant action of the (universal covering of) the Poincar e group. In particular this gives, together with our previous results, an intrinsi...

the neighborhood is a major factor in urbanism where habitation is characterized.in iranian traditional cities, the concept of neighborhood demonstrates the values of well-being, identity and sociability. neighborhoods can be approached into the following ways: external view that includes official boundaries, issues related to urban development and urban management. internal view that is based ...

In this paper, the effectiveness of the neighborhood crossover of EMO algorithms is discussed through the numerical experiments. The neighborhood crossover chooses two parents which are close to each other in the objective space. All the individuals are sorted in order of proximity in the objective space, and then neighborhood shuffle is conducted, which randomly replaces individuals in the pop...

2.1. Basic properties: separation, countability, separability, compactness, connectedness. A space X is Tychonoff if for u, v ∈ X, there exists a neighborhood of u not containing v (and by symmetry a neighborhood of v not containing u). It is Hausdorff if every two points can be separated by disjoint neighborhoods. It is regular if it is Tychonoff and every closed set and point not in the set c...

BACKGROUND To improve our understanding of the neighborhood environment - physical activity (PA) relationship, it is of importance to assess associations between neighborhood environmental characteristics and neighborhood-based PA. METHODS Participants' (N = 308; 45-65 years) light PA (LPA) and moderate-vigorous PA (MVPA) within a 400, 800, and 1600 m buffer around adults' homes was measured ...
