heoretical bases are developed in terms of complexvoltage/current unbalance factors at the POE. Thus, it isassumed that all voltage/current measurements in eitherpreconnection or postconnection stages at the POE areobtained as synchronized phasor quantities.• Installation (load) is represented as a coupled impedancematrix in the case of passive loads (coupling impedancesare present when converting unequal decoupled phaseimpedances into sequence domain) and as a decoupledimpedance matrix in the case of induction motors in thesequence domain

Slippage of DNA polymerase during DNA replica-tion and failure to repair mismatches is consideredas a mechanism for creation and hypervariability ofSSRs (Levinson & Gutman, 1987). Mutations atthe priming site i.e. SSR could prevent amplifica-tion of a fragment, as also in RAPD markers andthus give a presence/absence polymorphism. An in-sertion/deletion event within the SSR region or theamplified region would result in the absence of aproduct or length polymorphism, depending on theamplifiability of the resulting fragment size. Variab-ility in number of nucleotides within a microsatelliterepeat would result in length polymorphisms whenusing a 5’-anchored primer

This towering scheme is ideal since it keeps the coefficents of the irreducible polynomialsas small as possible. At some points during the pairing computation, it is required thatfinite field elements be multiplied byξ(for example, when multiplying two elements overFq12). Using the above towering scheme, multiplication byirequires one negation overFq,and multiplication byξrequires only one addition overFq2. For primes congruent to 3mod 8, we use the above towering scheme.We represent all prime and extension fields using a towering scheme as above, varyingthe choice ofξandvto suit the primeqin question

One consequence of Proposition 4.3 is thatForeward-searchis complete. An-other consequence is thatForeward-search’s search space is usually muchlarger than it needs to be. There are various ways to reduce the size of thesearch space, by modifying the algorithm toprunebranches of the searchspace (i.e., cut offsearch below these branches). A pruning technique issafeif it is guaranteed not to prune every solution; in this case the modifiedplanning algorithm will still be complete. If we have some notion of planoptimality, then pruning technique isstrongly safeif there is at least oneoptimal solution that it doesn#prune. In this case, at least one trace of themodified planning algorithm will lead to an optimal solution if one exists.Here is an example of a strongly safe pruning technique. Suppose thealgorithm generates plansπ1andπ2along two different paths of the searchspace, and supposeπ1andπ2produce the same state of the worlds. Ifπ1can be extended to form some solutionπ1π3, thenπ2π3is also a solution,and vice versa. Thus we can prune one ofπ1andπ2, and we will still beguaranteed of finding a solution if one exists. Furthermore, if the plan thatwe prune is whichever ofπ1andπ2is longer, then we will still be guaranteedof finding a shortest-length solution if one exists

When the blocks were subjected to 7 days of 95% RH, all velocitiesdecreased and the amplitude of the decrease was inversely propor-tional to the velocity value at the end of the freezing–thawing cycles.This means that, the higher the velocity had been, the lower it becameafter re-humidification. Finally when oven-dried (50 °C), samplespresented the same velocity independently of their hydric history.The last few observations are noteworthy because the elastic wavevelocities, and especially that of the elastic compressive wave Vp, pro-vide a non-destructive parameter that gives information on the dam-age of the sample. It is interesting to compare these results with thoseof the literature. Numerous studies have been carried out on differentsedimentary rocks.Gueguen and Palciauskas (1992)showed that thepresence of water (or any other low compressibilityfluid) in thepores of the rocks, and thus the degree of saturation, had a strong ef-fect on the value of Vp (Gueguen and Palciauskas, 1992). This effectcan be explained by the fact that the compressive wave velocity in
