The transportation and electric sectors are by far the largest producers of greenhouse emissions in the United States while they consume a significant amount of the national energy. The ever rising demand for these systems, the growing public concern on issues like global warming or national security, along with emerging technologies that promise great synergies between both (plug-in hybrid veh...

Recent years have seen a number of challenges to social stability and order, ranging from terrorist attacks and natural disasters to epidemics such as AIDS and SARS. Such challenges have generated specific policy responses, such as enhanced security at transportation hubs and planned deployment of a global tsunami detection network. However, the range of challenges and the practical impossibili...

In this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. In the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. It is assumed that the sequence of the trains in the network is known. The objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

increasing urban network has both positive (accessibility) and negative (air pollution) impacts. in this research air quality is chosen as key elements with respect to their critical roles in quality of life and urban health. the overall objective of this study is to develop a mathematical model to plan appropriate locations for residential land uses and urban transportation network development...

Nowadays, the Internet plays an important role in peoples' daily lives as well as their work, thus its resiliency is vital within its ecosystem. However, the uncoordinated patterns of inter-domain routing as well as the significant growth of the network and the traffic in Internet challenge the resiliency of Internet. Therefore, it is becoming urgent to find solutions to mitigate those issues. ...

Wireless Sensor Networks have some well known features such as low battery consumption, changing topology awareness, open environment, non reliable radio links, etc. In this paper, we investigate the benefits of Network Coding Wireless Sensor networking, especially resiliency. One of our main concern is the resiliency in Wireless Sensor Networks. We have seen that resiliency could be described ...

the objective of this study was to develop a cost minimizing pattern for cube sugar and sugar transportation from production centers to refinement and storage centers and finally to distribution and consumption  centers in  fars province. producing centers are marvdasht (27.3%), eghlid (27.9%), fasa (11.3%), kavar (7.3%) and mamasani (20.2%). some of the province’s cube sugar and sugar is provi...
