Flow Electrification Behavior: A New Parameter Involved

Flow electrification is a complex phenomenon and, in spite of extensive researches for many years by several groups all over the word, the origin of the process is not totally clarify. Indeed, even if the influence of many parameters has been established. However, the physicochemical process at the interface solid/liquid remains rather difficult to clearly understand because it is often controlled by impurities which are not well identified. Concerning the influence of the flow characteristics, it has been pointed out in various experiments that the wall shearing stress plays an important role on the ionic exchanges at the interface which control the wall current density. In this paper we analyze this behavior comparing the different experimental results that we previously obtained. Finally, we discuss the relation between the wall shearing stress and the wall current density.Fil: Moreau, O.. No especifíca;Fil: Cabaleiro, Juan Martin. Universidad de Buenos Aires.

Gravimetric evidences of active faults and underground structure of the Cheliff seismogenic basin (Algeria)

International audienceThe Cheliff basin (ex El Asnam) is known as one of the most seismic active zone in Algeria and the West Mediterranean region. We can cite the El Asnam earthquake which occurred in 10.10.01980 with magnitude of 7.3. It was generated by a thrust fault with NE–SW sinistral component. Until now, there is a little information about existence of deep active faults, which generate this strong activity. The gravity field is an important resource of information on crustal structure. The aim of this work is giving a reliable geometry of the major faults relative to the kinematics of this region.The results obtained from various filtered maps (derivatives, upward continuation) of the gravity data, were used to generate a structural map of the studied area. Whilst the continuous wavelet transform method can help in automatic detection of elongated structures in 3-D, to estimate their strike direction, shape and depth. It gives a 3-D image or a model of the region and confirms the existence of several faults, localized or inferred, from former geological studies

Building Trust in Human-Machine Partnerships

Artificial Intelligence (AI) is bringing radical change to our lives. Fostering trust in this technology requires the technology to be transparent, and one route to transparency is to make the decisions that are reached by AIs explainable to the humans that interact with them. This paper lays out an exploratory approach to developing explainability and trust, describing the specific technologies that we are adopting, the social and organizational context in which we are working, and some of the challenges that we are addressing
