Generative adversarial networks with bio-inspired primary visual cortex for Industry 4.0
2022
Biologicalization (biological transformation) is an emerging trend in Industry 4.0 affecting digitization of manufacturing and related processes. It brings up the next generation of manufacturing technology and systems that extensively use biological and bio-inspired principles, materials, functions, structures and resources. This research is a contribution to the further convergence of computer and human vision for more robust and accurate automated object recognition and image generation. We present VOneGANs, a novel class of generative adversarial networks (GANs) with the qualitatively updated discriminative component. The new model incorporates a biologically constrained digital primary…
Integration Data Model of the Bathymetric Monitoring System for Shallow Waterbodies Using UAV and USV Platforms
2022
Changes in the seafloor relief are particularly noticeable in shallow waterbodies (at depths up to several metres), where they are of significance for human safety and environmental protection, as well as for which the highest measurement accuracy is required. The aim of this publication is to present the integration data model of the bathymetric monitoring system for shallow waterbodies using Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicles (USV). As part of this model, three technology components will be created: a hydroacoustic and optoelectronic data integration component proposed by Dąbrowski et al., a radiometric depth determination component based on optoelectronic data u…
The Coupled Magmatic and Hydrothermal Systems of the Restless Aluto Caldera, Ethiopia
2020
Seismicity can be used to better understand interactions between magma bodies, hydrothermal systems and their host rocks—key factors influencing volcanic unrest. Here, we use earthquake data to image, for the first time, the seismic velocity structure beneath Aluto, a deforming volcano in the Main Ethiopian Rift. Traveltime tomography is used to jointly relocate seismicity and image 3D P- and S-wave velocity structures and the ratio between them (V P/V S). At depths of 4–9 km, the seismicity maps the top of a large low velocity zone with high V P/V S, which we interpret as a more ductile and melt-bearing region. A shallow (<3 km) hydrothermal system exhibits low seismic velocities and ve…
O projeto Mujeres Maestras del Perú. Estudo de caso sobre identidades de ensino
2018
El proyecto «Mujeres Maestras de Perú» nos acerca a las opiniones de veintiun maestras peruanas. Las que trabajan en entornos menos favorecidos e insisten en su precocidad vocacional. Las maestras nos hablan de dicho factor vocacional como de algo que ya aparece en su infancia en tanto que deseo explícito de dedicarse a la docencia. Nuestra investigación parte de un enfoque cualitativo, mediante un estudio de caso al que incorporamos elementos de rango artístico (Investigación basada en las artes). Utilizamos grabaciones audiovisuales como instrumento de recogida de datos. Desde la educación artística, visibilizamos las identidades del colectivo docente como homenaje y reivindicación profes…
Muerte e identidad en Final Fantasy IX
2020
espanolLos videojuegos se han desarrollado como medio de comunicacion audiovisual y social que sirven como reflejo verosimil de diferentes aspectos de la propia sociedad. En el caso que nos ocupa, vamos a analizar como se conciben la muerte” y la identidad” en el videojuego Final Fantasy IX. Asi, analizaremos la muerte dentro de la propia historia, y partir de dicho analisis, veremos de que forma se construyen las identidades de los personajes. Para ello, basaremos nuestro estudio en la semiotica, atendiendo tanto a aspectos visuales como sociologicos, puesto que la construccion de la identidad esta ligada a los elementos visuales del videojuego y en conexion con la muerte y las relaciones …
« Le pilotage par l’Etat de la formation des enseignants du début des années 1990 à nos jours et ses incidences sur le métier de formateur »
2014
L’objet de cet article est de questionner, dans une perspective historique, la manière dont l’État a organisé et a fait évoluer la formation des enseignants du début des années 1990 à nos jours. Il s’attache à mettre en lumière les ambitions qui ont présidé aux réformes et tente de montrer la manière dont le métier de formateur d’enseignants s’est constitué et a évolué. Le formateur avait acquis un certain nombre de savoir-faire, et plus généralement une certaine culture, qui pourraient conduire à affirmer qu’un processus de professionnalisation était en cours, et ce jusqu’au milieu des années 2000. Ce processus tendait à rassembler sous une même dénomination, celle de « formateur », des in…
Density Decline in a Mediterranean Seahorse Population: Natural Fluctuations or New Emerging Threats?
2021
Illegal wildlife trade is considered one of the most serious threats to biodiversity worldwide, along with habitat loss/degradation and overfishing of wild stocks. Seahorses are considered at high risk as these fish represent an important component of traditional Chinese medicine but are also sold as curios and ornamental fish. On a worldwide level, illegal trade is controlled by numerous laws and regulations, but it seems to continue by assuming more dynamic routes. In the Mediterranean Sea, Hippocampus guttulatus formed one of the largest populations at Mar Piccolo di Taranto in South-Eastern Italy. During the routine monitoring of this population in 2016, a dramatic density decrease was …
L’éthique, une potentialité : conséquences pour penser l’éducation scolaire
2018
Parler d’éducation à l’éthique c’est en général considérer cette dernière comme une entité c’est-à-dire comme quelque chose qui serait suffisamment défini pour constituer un élément du réel support à transmission. Pourtant, et les difficultés auxquelles sont confrontées les éducateurs le montrent assez bien, les questions éthiques sont délicates à définir : l’éthique implique de s’appliquer ou de faire appliquer des règles, mais ne dit rien sur la nature de ces règles. De ce point de vue, l’éthique est plus une potentialité vers laquelle il s’agit de tendre qu’une entité que l’on pourrait circonscrire pour en faire un objet d’apprentissage défini. Dans cet article, je me propose d’examiner …

In situ micro-Raman and X-ray diffraction study of diamonds and petrology of the new ureilite UAE 001 from the United Arab Emirates
2008
International audience; A new olivine-pigeonite ureilite containing abundant diamonds and graphite was found in the United Arab Emirates. This is the first report of a meteorite in this country. The sample is heavily altered, of medium shock level, and has a total weight of 155 g. Bulk rock, olivine (Fo79.8-81.8) and pyroxene (En73.9-75.2, Fs15.5-16.9, Wo8.8-9.5) compositions are typical of ureilites. Olivine rims are reduced with Fo increasing up to Fo96.1-96.8. Metal in these rims is completely altered to Fehydroxide during terrestrial weathering. We studied diamond and graphite using micro-Raman and in situ synchrotron X-ray diffraction. The main diamond Raman band (LO=TO mode at ~1332 c…
