Smart transportation based on big data traffic analysis is an important component of smart city. With millions of ubiquitous street cameras and intelligent analytic algorithms, public transit systems of the next generation can be safer and smarter. We participated the IEEE Smart World 2017 NVIDIA AI City Challenge which consists of two tracks of contests that serve this spirit. In the AI City T...

The street garment vendors are playing a significant role in the fields of the economic development through protecting resources (garment products) from such a position where they are treated as wastes; very much less valued products and creating the opportunity for self-employment. This study aimed at showing the economic contribution and the impact of the street vendors to the local community...

Methods: This paper is a part of comprehensive rapid assessment and response (RAR) research on street children in Tehran i...

The intelligent systems are becoming more important in life. Moving objects tracking is one of the tasks of intelligent systems. This paper proposes the algorithm to track the object in the street. The proposed method uses the amplitude of zernike moment on nonsubsampled contourlet transform to track object depending on context awareness. The algorithm has also been processed successfully such ...

E-commerce has been one of the success stories of the last decade. Developments in wireless communications and mobile computing have heralded an era of mobile commerce (m-commerce). Though a number of successful applications and services have been deployed, these are almost invariably inherently static in nature. By augmenting m-commerce with intelligent and autonomous components, the significa...

A four-sector cross-shaped urban microcellular system with intelligent switched-beam antennas is proposed. Each sector covers a street block with a base station located at an intersection, and an intelligent beam-switching scheme is used to locate mobile users in the most suitable beam coverage. Due to directional narrow-beam patterns and waveguide effects of tall buildings, radio signals along...

tire street children phenomenon is categorized as a social disorder that not only includes a great number of children and youngsters as society future capital with danger but also makes the society suffer of harms. therefore, in order to decrease this disorder we should understand its different dimensions and the factors influencing on it to find various scientific and practical solutions for i...

Nowadays, the expansion of the cities is an inevitable necessity; increasing the dependence of the citizens on motor vehicles and, consequently, making development of the transportation networks a necessity rather than an option. Thus, increasing car ownership and car use has created many problems for the cities, such as increasing greenhouse gas emissions, environmental pollution, casualties o...

in recent years many transformations have occurred in iranian society and women and girls still have a lot of worries about comes to urban public spaces. also, due to some ambiguities in defining the domain of public space in traditional islamic cities and gaps in the knowledge related to the kurdish cities, the main problem of this paper is how we can define a participatory approach to improve...
