To quantify if this scenario parameter is also relevant, we employ the Bayesian information criterion (BIC) =-=[10]-=- in the next section. The methodology to be used can be applied to other choices of scenario parameters, besides (4). III. MODEL COMPARISON BY BIC We first give a general description of the BIC, then ... |

Fig. 3 illustrates the difference between a stationary Markovian (SM) model and the generalized Markovian (GM) model via a causal diagram =-=[9]-=-, which is a directed graph that shows the causal relationship of the random variables. Intuitively, Sk characterizes different classes of energy-harvesting environments, such that in each class Ek is... |

For simplicity, we consider a first-order SM model, i.e., L = 1. Similar derivations can be made for L ≥ 1. Su... |

Some energy harvesters, e.g. the solar energy harvester in =-=[12]-=-, harvest either an approximately constant amount of energy (if Ẽk is large enough) or no energy at all in our empirical measurements. This justifies the use of the two-state quantizer in such cases.... |
