In this paper an emergency service vehicle (ESV) location problem has been considered in which it is assumed that each emergency call may require more than one ESV. In ESV location problem two factors should be known; the location of stations and the number of ESVs at each station. Hence, a nonlinear mixed integer programming model is presented in order to maximize the total response rate to th...

LPG storage tanks may be seriously threatened by a fire coming from nearby fuels or leakage appearance. The aim of the study was to prepare three-dimensional model release on car gas station under different environmental conditions. CFD simulations liquid and phase tank localized performed. First, ALOHA software applied determine mass flow rate, while Ansys used shape size hazardous zone. To re...

2.15 billion mobile phone users in the world and there are 50 million subscribers in Pakistan. The more mobile devices are sold, the more mobile services are developed and downloaded. Location Based Services (LBS) is one of those popular technologies. It provides valuable information based on user's location such as nearest gas station for drivers and nearest ATM in the vicinity, road route sel...

By taking the super-long railway tunnel as the object of research, based on setting problems of emergency stations adopted by super-long railway tunnels, from the viewpoint of people's safe evacuation, several aspects were studied, such as the mode of evacuation and rescue by adopting emergency station, the number and interval of the cross passage, and the people's safe evacuation time under di...

The user terminal The terminal provides a simple user interface consisting of a smart card system, keyboard, monitor, and printer. After inserting a smart card into the smart-card reader, the user keys in a password and selects the kind and amount of fuel. The user can check the smart card’s records and updated status. During refueling, the monitor displays the procedure’s progress. The printer...
