This paper compares two well known scan matching algorithms: the MbICP and the pIC. As a result of the study, it is proposed the MSISpIC, a probabilistic scan matching algorithm for the localization of an Autonomous Underwater Vehicle (AUV). The technique uses range scans gathered with a Mechanical Scanning Imaging Sonar (MSIS), and the robot displacement estimated through dead-reckoning with the help of a Doppler Velocity Log (DVL) and a Motion Reference Unit (MRU). The proposed method is an extension of the pIC algorithm. Its major contribution consists in: 1) using an EKF to estimate the local path traveled by the robot while grabbing the scan as well as its uncertainty and 2) proposing a method to group into a unique scan, with a convenient uncertainty model, all the data grabbed along the path described by the robot. The algorithm has been tested on an AUV guided along a 600m path within a marina environment with satisfactory results

Le protestantisme a-t-il un avenir? A-t-il toujours les moyens de ses ambitions fondatrices - réformer l'Eglise et faire résonner des accents prophétiques au-delà de ses frontières ? Le présent volume a pour but de dresser un état de la situation, d'examiner l'identité protestante sous l'angle de ses forces et de ses faiblesses, de se demander comment cette identité est susceptible de trouver sa place dans la situation actuellement en devenir. Le protestantisme n'est en effet plus ni ne peut plus être exactement ce qu'il était. Le monde autour de lui n'a cessé de changer et lui-même est passé par plusieurs mutations. Le problème de l'identité protestante s'esquisse désormais sur fond de modernité, voire de post-modernité - des étapes culturelles d'autant plus importantes que le protestantisme a directement participé à leur formation ou s'est constamment soucié d'en comprendre les incidences les plus décisives. Quels sont alors les risques, mais aussi les chances, de la tradition théologique et culturelle dont il est issu? Les contributions rassemblées ici explorent quelques aspects parmi les plus importants de cette problématique: la précarité, la morale, le rapport à la tradition, l'oecuménisme, le défi des images, etc.

Nominal Unification is an extension of first-order unification where terms can contain binders and unification is performed modulo α equivalence. Here we prove that the existence of nominal unifiers can be decided in quadratic time. First, we linearly-reduce nominal unification problems to a sequence of freshness and equalities between atoms, modulo a permutation, using ideas as Paterson and Wegman for first-order unification. Second, we prove that solvability of these reduced problems may be checked in quadràtic time. Finally, we point out how using ideas of Brown and Tarjan for unbalanced merging, we could solve these reduced problems more efficiently

Enhanced degradation of the fungicide metalaxyl was investigated in two soils: a gley humic (GH) and a Dark Red Latosol (LE), collected at sites never exposed to the fungicide. The soil samples were treated with successive applications of metalaxyl as a commercial formulation and 14C-metalaxyl in laboratory. Metalaxyl biodegradation was analyzed during 63 days by means of radiometric techniques to verify biomineralization and degradation product formation from the applied 14C-metalaxyl. Although biomineralization (maximum of 14 and 8% in the GH and LE soils, respectively), and partial degradation (about 32 and 48%, respectively) were detected in both soils, enhanced degradation was verified only in the GH soil. Results proved that metalaxyl behaves differently in soils.
