Étude d'un système de stéréo-vision hybride
2013
National audience; On considère dans ce travail un système de vision hybride fixe composé d'une caméra fisheye et d'une caméra PTZ dans un environnement rigide. Nous souhaitons être en mesure d'orienter la caméra mécanisée sur une cible visible depuis l'image omnidirectionnelle de manière à obtenir une image de bonne définition de l'objet d'intérêt à partir de la caméra PTZ. Nous proposons dans cet article d'utiliser la modélisation sphérique des images ainsi que les propriétés de la géométrie épipolaire afin d'initialiser la localisation de la cible dans la caméra PTZ.

Greening a university campus: trends of energy consumption and possible sustainable paths
2014
Recent years have seen an increasing public interest in issues related to energy saving and environmental pollution reduction of public buildings, such as those in university campuses, that should set an example of sustainable development. University campuses are usually characterized by the daily presence of a high number of people working and living in a relatively limited area. They are sites of a wide spread of functions, ranging from teaching to laboratory activities, from housing and food preparation to local transportation. All these activities require remarkable amount of energy that, actually, are not always utilized with the best possible efficiency. This calls for a deep reconsid…
Institutional arrangements for sustainable development: Cases from the Navarra Province (Spain).
2015
After more than 20 years of the Earth Summit, Sustainable development is still recognized as one of the main challenges of the XXIst century. World leaders are putting new emphasis on the need to resolve urgent environmental challenges underlining their link with the wellbeing of humankind and the very conditions that made life possible on the planet. We are immersed in complex socio-ecological systems where sectoral or simplified responses are not adequate. A more systemic vision is imperative to effectively address the challenges faced. New approaches are being developed to integrate social, environmental and economic concerns in all human activities. Particular attention is given to deco…
Drugie stanowisko prześwietlika platanowego Corythucha ciliata (Say, 1832) (Hemiptera: Heteroptera: Tingidae) na Górnym Śląsku
2022
The sycamore lace bug Corythucha ciliata (Say, 1832) has a North American origin and is one of the most abundant and widespread pests on plane trees (Platanus spp.) across the globe. It has been introduced to Europe, South America, Asia, Australia, and Africa during the last sixty years. In Poland, it has been recorded since 2009 in 28 localities distributed in four of its southern zoogeographical regions. The present paper describes the second record of this species in Upper Silesia.
CA3–CA1 long‐term potentiation occurs regardless of respiration and cardiac cycle phases in urethane‐anesthetized rats
2023
Breathing and heartbeat synchronize to each other and to brain function and affect cognition in humans. However, it is not clear how cardiorespiratory rhythms modulate such basic processes as synaptic plasticity thought to underlie learning. Thus, we studied if respiration and cardiac cycle phases at burst stimulation onset affect hippocampal long-term potentiation (LTP) in the CA3–CA1 synapse in urethane-anesthetized adult male Sprague–Dawley rats. In a between-subjects design, we timed burst stimulation of the ventral hippocampal commissure (vHC) to systole or diastole either during expiration or inspiration and recorded responses throughout the hippocampus with a linear probe. As classic…
Bailiaspis (Trilobita) with English affinities from the Mansilla Formation (Cambrian Series 3 of the Iberian Chains; NE Spain)
2020
A new study of the trilobite record in the Mansilla Formation (Iberian Chains, NE Spain) has led to the discovery of the presence of Bailiaspis aff. tuberculata, B. cf. tuberculata and Bailiaspis sp., the first certain citation of this genus in the Mediterranean subprovince. The age of the findings extends from Eccaparadoxides asturianus Zone (upper Leonian) to the lowermost Badulesia tenera Zone (lower Caesaraugustan), which correspond to the upper part of Stage 5 of Cambrian Series 3 and, probably, the lowermost Drumian. The specimens show the cranidial anterior border expanding backwards, forming a plectrum that is characteristic of Bailiaspis. The main characters of the three taxa inclu…
