This paper deals with the design of on board networks in satellites (also called Traveling wave tube Amplifiers (TWTA)). These networks should connect signals arriving on some ports of the satellite to amplifiers, even in case of failures of some amplifiers. They are made of links and expensive switches each with 4 links. So, the aim is to design networks having as few switches as possible and ...

Railway planners have several tools to simulate the operation. Simulation allows the evaluation of the railway system’s quality by different points of view. Analyses of timetable stability and robustness include several indicators: recovery time and total delay among others. This paper formulates a model to describe the delay on a railway line. The total delay is characterized as a polynomial f...
