A time-domain approach to the extinction paradox for scattering of electromagnetic waves

The extinction paradox states that a perfectly electric conducting target which is large compared to the wavelength removes from the incident radiation exactly twice the amount of power it can intercept by its geometrical cross section area. In this paper, the extinction paradox is generalized to include temporally dispersive material parameters with finite values of the permittivity and the perme

Dynamic speed adaptation in adverse conditions

Accident risk in adverse conditions (wet/slippery road, darkness) increases drastically and speed adaptation in these conditions is often inappropriate. The safety potential of more appropriate speeds in these situations is high. Appropriate highest speeds in different conditions are discussed. A system, which limits the maximal speed of the vehicle in the actual situation (on wet/slippery road, a
