Assume that there are no two time instances in set T that are exactly the same.

Tables 1 and 2 show computational errors in the L 2 -norm and the energy norm at four time instances t = 5.0, t = 10.0, t = 15.0 and t = 20.0, the corresponding EOC during all computations.
The current system is shown for six time instances (UTC = 4 00, 8 00, 12 00, 16:00, 20 00, 24:00) for 1990-05-15 with the solar terminator of the respective day on top (blue shade).
If no loop closures are detected, then the ESDF is simply stacking all pose estimates, but once a loop closure is detected and the relative pose between the two time instances is calculated, the ESDF allows for the whole trajectory to be updated using this new information.
On the left, the three images correspond to the spatial field at three different time instances, where the star symbols indicate the sensing nodes.
In addition, we also computed cross-correlation between two identical segments of two decaying tails of same "hand-clap" recorded at two different time instances.
The SBA performs repetition coding at two consecutive time instances while the ESA performs repetition coding at two carefully chosen time instances.
And, shown in Figure 3 is the plot of cross-correlation function of two time-aligned segments of decaying tails of identical "hand-clap" recordings made at two different time instances with M i c 1 in E5 (i.e., by playing the same "hand-clap" recording twice).
The computed EOCs at all four monitoring time instances keep asymptotically the same orders, i.e., err h 0 = O ( h 2 ) and err h 1 = O ( h ), for piecewise linear approximations and confirm the spatially suboptimal a priori error estimates (66) with respect to the L 2 -norm and spatially optimal estimates (67) in the energy norm, respectively.
