The unified approach comprises global reachability analysis at the discrete event system level, local reachability analysis at the continuous-time dynamical system level and a merging of the results of these two methods using a discrete-path search algorithm.
For the resulting discrete path segments, a static optimisation problem is formulated to determine the path independently of the considered scenario.
Second, we have not established that the discrete path integral converges to a well-defined functional measure in the continuum limit.
More recently, Tsunoda et al. (2016a, b) showed that a striation (i.e., a discrete OGC path in a TEP experiment) can, indeed, persist for more than 5 h, as can be seen from Fig. 9 (see "Three ionosondes and TEP experiment" section).
Two algorithms are provided to generate smooth trajectories from discrete path sequences.
The discrete path activity parameters are in turn estimated conditionally on the delays and the delay rates using a grid-based method [13], which is appropriate to optimally estimate a discrete state space.
The Freeman chain code is a common and useful way for representing discrete paths by means of words such that each letter encodes a step in a given direction.
We assume that a propagation channel consists of L discrete paths with different time delays.
Circuit theory is an appealing model because, rather than modeling discrete paths that assume the disperser has prior knowledge of the landscape, it uses random walkers to model an overall resistance to movement.
The channel coefficients among the nodes are generated by using a tap-delay-line (TDL) model with six discrete paths.
The code presented here provides these required capabilities, but has gone beyond the original design and could be used as is or easily adapted for the visualization of other particulate transport where transport occurs on discrete paths.
