Multiservice UAVs for Emergency Tasks in Post-disaster Scenarios
UAVs are increasingly being employed to carry out surveillance, parcel
delivery, communication-support and other specific tasks. Their equipment and
mission plan are carefully selected to minimize the carried load an overall
resource consumption. Typically, several single task UAVs are dispatched to
perform different missions. In certain cases, (part of) the geographical area
of operation may be common to these single task missions (such as those
supporting post-disaster recovery) and it may be more efficient to have
multiple tasks carried out as part of a single UAV mission using common or even
additional specialized equipment.
In this paper, we propose and investigate a joint planning of multitask
missions leveraging a fleet of UAVs equipped with a standard set of accessories
enabling heterogeneous tasks. To this end, an optimization problem is
formulated yielding the optimal joint planning and deriving the resulting
quality of the delivered tasks. In addition, a heuristic solution is developed
for large-scale environments to cope with the increased complexity of the
optimization framework. The developed joint planning of multitask missions is
applied to a specific post-disaster recovery scenario of a flooding in the San
Francisco area. The results show the effectiveness of the proposed solutions
and the potential savings in the number of UAVs needed to carry out all the
tasks with the required level of quality
Idioma y saberes otomÃes. rescate y práctica en la vida cotidiana
Este artÃculo contiene los resultados de la investigación sobre el papel de las mujeres otomÃes en la transmisión del idioma en el ámbito de la vida cotidiana. Se buscó rescatar la relevancia del idioma materno para el funcionamiento de la vida social de los otomÃes y reconocer la relevante función de las mujeres para que el otomà siga siendo un idioma vivo. Este es, particularmente para las mujeres, el referente generacional, la herramienta a través de la cual han adquirido un amplio reservorio de saberes. Desde el confinamiento de sus roles tradicionales, ellas encuentran en la esfera doméstica un espacio de privacidad y de confianza para hablarlo y forjar el respeto de los demás. La práctica cotidiana de sus saberes femeninos en ese espacio constituye uno de los vehÃculos que prolonga la vigencia y el desarrollo de su idioma

The guilty brain: the utility of neuroimaging and neurostimulation studies in forensic field
Several studies have aimed to address the natural inability of humankind to detect deception and accurately discriminate lying from truth in the legal context. To date, it has been well established that telling a lie is a complex mental activity. During deception, many functions of higher cognition are involved: the decision to lie, withholding the truth, fabricating the lie, monitoring whether the receiver believes the lie, and, if necessary, adjusting the fabricated story and maintaining a consistent lie. In the previous 15 years, increasing interest in the neuroscience of deception has resulted in new possibilities to investigate and interfere with the ability to lie directly from the brain. Cognitive psychology, as well as neuroimaging and neurostimulation studies, are increasing the possibility that neuroscience will be useful for lie detection. This paper discusses the scientific validity of the literature on neuroimaging and neurostimulation regarding lie detection to understand whether scientific findings in this field have a role in the forensic setting. We considered how lie detection technology may contribute to addressing the detection of deception in the courtroom and discussed the conditions and limits in which these techniques reliably distinguish whether an individual is lying
