Performance criteria investigated in the simulation study include power saving efficiency (denoted by PSE), average delay (denoted by AvgD), and signaling overheads for DRX operation (denoted by SignalDRX) and CQI reporting (SignalCQI), respectively.
The fourth performance criterion (denoted by T running) is the total running time for every method, in MATLAB, for 300 Monte Carlo runs in s on an Intel Core i5 2.80 GHz.
The situation under H 1 is similar to that under H 0, except that the detection performance is denoted by p d,i and ({p_{d,i}^{prime }}).
Models based on the natural log of PM10 2.5 levels and the iterative covariate selection approach proposed by Su et al. (2009) showed generally poorer prediction performance as denoted by lower CV R and higher RMSE than those presented here (data not shown).
This performance measurement is denoted by "weighted BER (wBER)" in the Results section.
The above operation is denoted by H.insert L).
Let p A i denote the vector of those parameters of nodes in A i, with its ordering of parameters determined by the sorted indices in A i. Associated with each node i is a performance metric or cost, denoted by M i p A i, which is a function of those parameters in the neighbor list A i of node i.
In order to compare the performance of the estimator (denoted by ALS) given by (2.6) with those of the ordinary least squares estimator (LS), the weighted least squares estimator (WLS), and the maximum likelihood estimation (MLE), we compute the mean square errors based on the four methods: the ALS, the LS, the WLS, and the MLE.
For the purpose of comparison, the results for MSE performances of the optimal PPSAM, denoted by O-PPSAM and the suboptimal PPSAM, denoted by SO-PPSAM as well as the CRB are shown in Figure 4.
The performance of an MHSV is mainly denoted by the hydrogen storage time and the capacity of the absorption and desorption.
