Query: Performability analysis of the second order semi-Markov chains: an
  application to wind energy production   In this paper a general second order semi-Markov reward model is presented.
Equations for the higher order moments of the reward process are presented for
the first time and applied to wind energy production. The application is
executed by considering a database, freely available from the web, that
includes wind speed data taken from L.S.I. - Lastem station (Italy) and sampled
every 10 minutes. We compute the expectation and the variance of the total
energy produced by using the commercial blade Aircon HAWT - 10 kW.
