lthough software engineers generally agree that software measurement must be goal oriented, little has been published on the results of shifting to goal-orientation and still less on how to systematically make that transition. Thus, when we at Schlumberger RPS decided to adopt the Goal/Question/Metric approach, we resolved to document each step and record our experiences at each stage of the tr...

It is assumed that many measurement programs fail because of the lack of normative models to assess a measurement program in advance. Our last years ESCOM presentation was about enhancing GQM with the characteristics of software development and software products. This enhancement improves the definition process of a measurement program. Schlumberger RPS is continuing its measurement program suc...

The Steiner tree problem which is known to be NP-Complete is the following. Given a weighted undirected graph G = (V;E), and a set X V of terminals, the objective is to nd a tree of minimum cost which connects all the terminals. If the graph is directed, in addition to X, we are given a root r 2 V , and the objective is to nd a minimum cost arborescence which connects the root to each of the te...

Geoelectricity is a geophysical method that conducted by injecting an electric current into the earth’s interior. This study objected to map aquifer aquifers using geoelectric with Schlumberger electrode configuration consisting of 4 sounding points. The measurement results are then processed IP2WIN software which produces real resistivity as function depth. correlation between points three-dim...
