In februari 2011 heeft de IANA de laatste IPv4-adresblokken uitgedeeld aan de regionale instanties die deze aan ISP's, bedrijven en organisaties toewijzen. De verwachte groei van het internet leidt hierdoor tot adrestekorten. ISP's in groeimarkten (glasvezel, mobiel) zullen als eerste worden getroffen. …

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies …

Optimization routines for battery, supercap and fuel cell stack in a fuel cell based propulsion system face two problems: the tendency to cycle beating and the necessity to maintain identical amounts of stored energy in battery and supercap at the start and end of the driving cycle used in the simulation. …

Fuel cells are expected to play an important role in the near future as prime energy source on board of road-going vehicles. In order to be able to test all important functional aspects of a fuel cell hybrid drive train, the Automotive Institute of the HAN University has decided to realize a stationary …
