AffectiveROAD system and database to assess driver's attention

Abstract: Thanks to the rise of new wearable and non-intrusive sensor technology, Internet of Things (IoT) contributes in human daily life improvement. In the context of smart vehicles, human affective monitoring should be based on a context-aware system in order to consider the interactions between the driver, the vehicle and the ambient environment. In this paper, we propose AffectiveROAD platform, that senses the human physiological changes, the ambient environment inside the vehicle, and the vehicle speed. Thanks to this platform, several driver's state indicators such as stress and arousal may be developed and validated. Two types of wireless physiological sensors are used to monitor the electrodermal activity, the heart rate, the skin temperature, the respiration, and the hand movement of the driver. Moreover, we developed a sensor network allowing to capture the ambient temperature, humidity, pressure, and luminosity. The purpose of this paper is to describe a real-world driving protocol allowing to collect data using IoT-based materials and to announce the publication of a database for driver's state monitoring research. A partial database concerning the physiological and the environmental information is available on request, for public use.

Aptian sedimentation: an example of interaction between tectonics and eustatics in Central Tunisia

Abstract: Abstract To reconstruct the sequence evolution and distribution of deposits during the Aptian in the Central Tunisian platform, the present study was mainly based on a sedimentological approach. The palaeogeographical reconstruction shows an inner and an external platform separated by the highs of the Central Tunisian islands. These are characterized by carbonate-dominated deposits evolving towards the north into a pelagic marl-dominated sedimentation. The NW-SE-to east-west-directed faults show an important sedimentary control. In fact, a system of tilted blocks located towards the SW characterizes a large part of the platform. The subsidence evolution during the Aptian was marked by a recovery of extensional tectonics. Finally, some halokinetic vertical movements were responsible for several highs during the latest Barremian. The Central Tunisian platform evolution was controlled by drift of the African platform during the opening of the Atlantic Ocean.
