During the last years, agile methods like eXtreme Programming have become increasingly popular. Parallel to this, more and more organizations rely on process maturity models to assess and improve their own processes or those of suppliers, since it has been getting clear that most project failures can be imputed to inconsistent, undisciplined processes. Many organizations demand CMMI compliance ...

The switching-rate capability of mm-wave InGaAs PIN diodes of various sizes was evaluated for the first time by measuring their response times under various bias conditions. The dependencies of InGaAs PIN diode switching times are discussed, and the results are correlated with their DC characteristics. InGaAs PIN diodes demonstrated short switching times (fall time τF=250ps and rise time τR=130...

A new type of rechargeable Mg battery is demonstrated, which achieves charge transfer through simultaneous transport of Mg(2+) cations and halogen anions during electrochemical cycling. The novel Mg/AgCl battery shows remarkable rate capability up to 10 C and excellent cyclability at high rates, with a flat plateau at 2 V.
