We extend the Stochastic Subscriber Line Model by the introduction of shortest-path trees which are obtained by splitting up the segment system of the typical serving zone at its crossings and endings. Due to reasons in the complex field of cost and capacity estimation in telecommunication networks, it is desirable to gain knowledge about distributional… (More)

Shortest-path trees play an important role in the field of optimising fixed-access telecommunication networks with respect to costs and capacities. Dis-tributional properties of the corresponding two half-trees originating from the root of such a tree are of special interest for engineers. In the present paper, we derive parametric approximation formulas… (More)

When arithmetic components are parallelized, fault-prone interconnections can tamper results significantly.A dvances in feature size shrinking lead to as teady increase of errors caused by faulty transmission. We suggest to employresilient data encoding schemes to offset these negative effects. Focusing on parallel signed-digit based arithmetic, frequently… (More)
