EN In this paper we introduce a state-estimation method that uses a short-term memory to calculate the current state. A common way to solve state estimation problems is to use implementations of the Bayesian algorithm like Kalman filters or particle filters. When implementing a Bayesian filter several [...]

EN We use a simple formalism to calculate the conductance of any quantum network consisting of single-channel one-dimensional quantum wires in the presence of Rashba spin-orbit coupling and a coupling magnetic field. We show that the Rashba effect may give rise to an electron localization phenomenon si[...]

EN The estimation of a vehicle configuration in its environment is mostly solved by Bayesian methods. Interval analysis allows an alternative approach: bounded-error localization. Such an approach provides a bounded set of configuration that is guaranteed to include the actual vehicle configuration. Th[...]
