Ricerca di soglie critiche per un test su matrici di confusione
No full textThis paper will discuss misclassification errors induced by human judgment. Facing different classifications coming from different trials, often researchers have to evaluate the goodness of classification proposed. Particularly, we propose an interesting application concerning olfactory measurement. In that field the accuracy of a confusion matrix is crucial, because the classification suggested by a panel of experts is collected by means of a confusion matrix.
The analysis of a confusion matrix we will perform in this study serves both to evaluate skills of judges, of whom the panel is composed, and to evaluate the discriminant capability of the element used to make the experiment. This work will focus in establishing critical thresholds for the test through which we assess not random classification
Electric field under an MV line supported by concrete poles
No full textThis paper presents a study of the electric field under a three-phase medium voltage (MV) power line supported by concrete poles. The analyzed configuration is a pole-top-pin construction. An analytical model has been developed for the three-phase wires assuming three straight cylindrical conductors whose axes have been put parallel to each other and to the ground, and for the concrete pole a cylindrical conductor placed in a vertical position. Simple analytical formulas have been obtained for the three components of the electric field in the vertical plane containing the axis of the conductor representing the central top wire. The validity range of the model is from the ground to one quarter of the height of the concrete pole. The analytical expressions have been checked against the numerical data obtained by a 3-D numerical analysis performed by using the charge simulation method. Finally, the results have been experimentally validated. The analytical model reported here is a new easy tool for the evaluation of the electric field for the analyzed geometry

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
