“…At the moment we are at the first stage that consists in comparing the results of P S-Merge with the results found in the literature, and as the reader can verify this proposal agrees in most of the cases with the results of other merging operators, particularly those of [1,2,4,5].…”

“…Instead of using distance measures, as in current approaches [1,4,2,5], we measure the degree of satisfaction of each agent by Partial Satisfiability of its beliefs. The elected state(s) of the merge will be those whose values maximize the sum of the Partial Satisfiability of the bases.…”

Merging operators try to define the beliefs of a group of agents according to the beliefs of each member of the group. Several model-based propositional belief merging operators have been proposed which use distance measures and aggregation functions. This paper introduces the notion of Partial Satisfiability which is an alternative way of measuring the satisfaction of a formula since this notion lets us have satisfaction values in the interval [0,1]. Partial Satisfiability allows us to define model-based merging operator. The proposal produces similar results to other merging approaches, but while other approaches require many merging operators in order to achieve satisfactory results for different scenarios this proposal obtains similar results for all these different scenarios with a unique operator. Moreover, unlike most of model-based approaches, this approach considers the case where the belief bases are inconsistent. The framework presented is in a preliminary state and further analysis of its properties is needed in order to characterize the proposed merging operator in terms of postulates. 625 978-81-904262-7-5 (RPS) c 2007 IFAAMAS

“…Comparing the (K s − N) index with the rotation period of single stars enables us to compare our results to the theoretical frameworks which use single star + disk scenarios. Furthermore, there is some evidence that the presence of a companion affects the evolution of a disk around a PMS object (Meyer et al 1997b;Ghez et al 1994). Jensen et al (1996) and Jensen & Mathieu (1997) present convincing evidence that disks from 50-100AU are affected by the presence of binary companions over this range of separations.…”

We present mid-IR N-band (λ ef f = 10.2µm) photometry of a carefully selected sample of T Tauri stars thought to be single from the Taurus-Auriga molecular cloud. Infrared excesses in these stars are generally attributed to circumstellar dust-disks. Combining observations at 2.16µm (K s -band) and 10.2µm (N-band) we probe a region in the circumstellar dust-disk from a few stellar radii through the terrestrial planet zone (0.02-1.0AU). By analyzing the distribution of the (K s − N) color index with respect to previously measured photometric rotation periods we investigate what role circumstellar disks play in the rotational evolution of the central star. The resulting positive correlation between these two variables is consistent with the notion that a star-disk interaction facilitates the regulation of angular momentum during the T Tauri stage. We also demonstrate, how including non-single stars in such an analysis will weaken any correlation in the relation between (K s − N) color and period. To further understand disk properties we also present SEDs for a few objects with new ground based Mband (λ ef f = 4.8µm) and Q-band (λ ef f = 20µm) data and compare them to a geometrically thin, optically-thick disk model.
