in this paper, vehicle’s fuel consumption and exhaust emissions are investigated in different driving conditions based on driving segments clustering. driving data collection is performed using global positioning systems in real traffic conditions. the driving data is clustered into five groups using k-means clustering technique. vehicle’s fuel consumption and exhaust emissions (i.e. hc, nox a...

in this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (dde) is presented. the main idea is that of incorporating the driver intent in the control of the vehicle. the driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. to induce a risk...

different recovery mechanisms are activated during the production from reservoirs. wells sometimes are kept with the injection. therefore the evaluation of injection indices depended on material injection, seems to be necessary. this study is going to determine the drive indices for a reservoir by making a model using eclipse. the model consists a gas cap and aquifer, in which there is an injec...

The core element of traditional simulation is a fixed database which is overlaid by a traffic model. Despite obvious efficiency of simulator use, shortcomings must be seen in (1) imperfect reality and control, (2) fixed sequencing of scenarios which cannot be altered during simulation, and (3) missing of objective evaluation of drivers’ performance. Therefore, at the University of Wuerzburg a n...
