SPICE will then terminate the run because both the AC and transient analyses require an initial stable operating point in order to proceed. During the transient analysis, this iterative process is repeated for each individual time step. If the node voltages do not settle down, the time step is...
During the transient period after a link failure the network cannot guarantee the agreed service levels to user data. This is due to the fact that forwarding tables in the network are inconsistent. Moreover, link states can inadvertently be advertised wrong due to protocol time outs, which may...

Troubleshooting Client-Side Failure Problem This problem occurs when there is a signal payload loss in the following conditions: If the fiber cut occurs at the client-side in the direction from the client to the NCS 1020, the LOS...
As stated before, convergence is a transient phenomenon; that is, it concerns the period from the initial kick-off point to the steady state. The steady state was also discussed for stationary environments, that is, environments in which the unknown parameter vector as well as the underlying ...
(a) In a SW graph with size\(n = 1000\)and average degree\(deg_{avg} = 20\), after a faster transient phase, the logarithm of the normalised error decreases linearly but at a slower rate than the complete graph of the same size. The convergence rate can be estimated as the angular...
The mean and standard deviation plots (Factor of Safety, or Probability of Failure), are obtained by recalculating the mean and standard deviation of the results, after EACH sample iteration of the Probabilistic Analysis. The minimum Factor of Safety plot simply keeps track of the minimum safety ...
