This work presents new elements of understanding for the microwave-based gas sensors behavior at room temperature. A TiO2-covered microstrip interdigital capacitor was submitted to various ethanol concentrations and showed a proportional response in the 1–10 GHz microwave range. For each concentration and right after ethanol injection, the sensor response presented a slight overshoot which is o...

We present the first attempt of charge carrier transport modeling in III-nitride multipleQW light-emitting diode structures which takes into consideration ballistic overshoot of the device active region. For the purpose of this study, the drift-diffusion based Transport module of our software package has been complemented by a simple model of ballistic carrier transport which proved to be essen...

A dual formulation for the problem of determining absolute performance limitations on overshoot, undershoot, maximum amplitude and fluctuation minimisation for continuous-time feedback systems is constructed. Determining , for example, the minimum possible overshoot attainable by all possible stabilising controllers is an optimisation task that cannot be expressed as a minimum-norm problem. It ...

A collisionless shock is a self-organized structure where fields and particle distributions are mutually adjusted to ensure stable mass, momentum energy transfer from the upstream downstream region. This adjustment may involve rippling, reformation or whatever else needed maintain shock. The inside front produced due motion of charged particles, which in turn governed by fields. overshoot arise...
