BACKGROUND Physical activity is essential for health; walking is the easiest way to incorporate activity into everyday life. Previous studies report positive associations between neighbourhood walkability and walking but most focused on cities in North America and Australasia. Urban form with respect to street connectivity, residential density and land use mix-common components of walkability i...
Persistent trends in overweight and obesity have resulted in a rapid research effort focused on built environment, physical activity, and overweight. Much of the focus of this research has been on the design and form of suburbs. It suggests that several features of the suburban built environment such as low densities, poor street connectivity and the lack of sidewalks are associated with decrea...
INTRODUCTION Prevalence of walking and cycling for transport is low and varies greatly across countries. Few studies have examined neighborhood perceptions related to walking and cycling for transport in different countries. Therefore, it is challenging to prioritize appropriate built-environment interventions. OBJECTIVES The aim of this study was to examine the strength and shape of the rela...
A reliable, punctual, and spatially accurate dataset of sidewalks is vital for identifying where improvements can be made upon urban environment to enhance multi-modal accessibility, social cohesion, residents' physical activity. This paper develops a synthetically new spatial procedure extract the sidewalk by integrating detected results from aerial street view imagery. We first train neural n...
Urban space, as a place for social interaction, has a very important role in image of the cities and also in place competition between them. These issues along with the outstanding demands of citizens for the quality of urban spaces have led the urban authorities to reconsider such spaces, as Marvi Alley, Naser Khosrow, and Sabzeh Meidan, through definition and implementation of urban projects ...
UNLABELLED BACKGROUND Neighborhood walkability has been associated with physical activity in several studies. However, as environmental correlates of physical activity may be context specific, walkability parameters need to be investigated separately in various countries and contexts. Furthermore, the mechanisms by which walkability affects physical activity have been less investigated. Base...
In theoretical chemistry, -modified Wiener index is a graph invariant topological index to analyze the chemical properties of molecular structure. In this note, we determine the minimum -modified Wiener index of graph with fixed connectivity or edge-connectivity. Our results also present the sufficient and necessary condition for reaching the lower bound.
the stability of a communication network composed of processing nodes and communication links is of prime importance to network designers. as the network begins losing links or nodes, eventually there is a loss in its effectiveness. thus, communication networks must be constructed to be as stable as possible, not only with respect to the initial disruption, but also with respect to the possible...
conclusions the current study showed significant association between the rosenberg self-esteem test results and smoking, and illegal drug abuse like heroin, pills, alcohol, nas, and other substances. therefore, increasing self-esteem is essential for preventing the adolescents’ emotional and behavioral disorders. this fact could guide us to the new approaches for smoking and drug-abuse preventi...
The construction and placement of tombs on either side of an inner or outer city street, and with it, the formation of decorated facades on both sides of a path, was common during the reign of the Timurids. Early in this era, Timur built a complex inside the shahr-i sabz, which consisted of a street on either side of which the Timurid courtiers built tombs for themselves and formed the body aro...
