culture has always been regarded as the most important element of human communities; we can easily observe cultural changes. what causes these changes has been a matter of controversy. the issues such as people’s increasingly getting detached from each other, psychopathy, behavioral abnormalities, traditions being increasingly faded away, malformation, extravagancy and value conversion into ant...

Rapid urbanization and increasing demand for transportation burdens urban road infrastructures. The interplay of number of vehicles and available road capacity on their routes determines the level of congestion. Although approaches to modify demand and capacity exist, the possible limits of congestion alleviation by only modifying route choices have not been systematically studied. Here we coup...

This study aims to redefine spaces of learning to places of learning through the direct engagement of local communities as a way to examine and learn from real world issues in the city. This paper exemplifies Smart City Learning, where the key goal is to promote the generation and exchange of urban design ideas for the future development of South Bank, in Brisbane, Australia, informing the crea...

this paper proposes an efficient network architecture to improve energy consumption in wireless sensor networks (wsn). the proposed architecture uses a mobile data collector to a partitioned network. the mobile data collector moves to center of each logical partition after each decision period. the mobile data collector must declare its new location by packet broadcasting to all sensor nodes. h...

Many wireless protocol simulation studies are performed under the assumptions that (i) nodes travel in a random fashion in unobstructed environments, and that (ii) radio wave propagation modeling is based on the freespace principle. We propose an urban mobility model, where mobile nodes traverse city streets using a variety of movement modes and where the urban environment is used as an input i...

background: although it is one of the most toxic nonradioactive elements, mercury is widely used in dental amalgam. mercury is a toxic element which can damage various organs such as central nervous system, renal, respiratory and hematologic systems. the adverse health impacts associated to exposure to some common sources of electromagnetic fields including laptop computers, mobile phones, mri ...

Large-scale urban sensing data such as mobile phone traces are emerging as an important data source for urban modeling. This study represents a first step towards building a methodology whereby mobile phone data can be more usefully applied to transportation research. In this paper, we present techniques to extract useful mobility information from the mobile phone traces of millions of users to...
