We compare the cost-efficiency of optical networks based on mixed datarates (10, 40, 100Gb/s) and datarateelastic technologies. A European backbone network is examined under various traffic assumptions (volume of transported data per demand and total number of demands) to better understand the impact of traffic characteristics on cost-efficiency. Network dimensioning is performed for static and...

We analyse maintenance cost data for Swedish railway infrastructure in relation to traffic volumes and network characteristics, and separate the cost impact from passenger and freight trains. Lines with mixed passenger and freight traffic, and dedicated freight lines are analysed separately using both log-linear and BoxCox regression models. We find that for mixed lines, the Box-Cox specificati...

Wireless Sensor Networks (WSN) has recently experienced a significant development. New techniques and communication protocols emerged as well as physical implementations of network node mainly based on mixed signal microcontrollers and processors (MSP – Mixed Signal Processors).Control applications over wireless sensor networks require timely, reliable, and energy efficient communications. This...

Car-following behaviour is well studied and analyzed in the last fifty years for homogeneous traffic. However in the mixed traffic, following behaviour is found to vary based on type of lead and following vehicles. In this study, a neural network based model is proposed to predict the following behaviour for different lead and following vehicle-type combinations. Performance of the model is stu...
