Anytime, Anywhere: measuring movement using miniaturized wearable sensors
Andrea CEREATTI (Univ. de Sassari / PolyTechnique de Turin). Professeur Invité par Guillaume RAO et Fabrice SARLEGNA à l'ISM du 11 février au 10 mars 2020.
Recent technological advances in microelectromechanical system technology has opened new possibilities in the domain of human movement analysis, enabling us to “follow” participants outside the laboratory and to monitor individuals in real-world conditions. Magnetoinertial measurement units (MIMU), supplemented by other wearable technologies show great potential for capacity and performance assessment, diagnosis and intervention planning, and educational purposes. This seminar will outline state of-the-art measurement and estimation methods for the description of human joint kinematics and digital mobility parameters using MIMUs. It will also highlight the extent that validity depends on sensor modality, data fusion techniques, biomechanically derived features and the techniques employed.

Additive Manufacturing (AM) provides the agility needed to rapidly make innovative customized complex products and replacement parts that are not realizable by traditional manufacturing technologies or are required to be produced in low volumes. Several technical barriers exist, however, that prevent AM processes from reaching their full potential. The recent roadmapping activities for AM outline research recommendations in several areas to advance the industry and emphasize that the ability to achieve predictable and repeatable operations is critical. The issues with surface quality, part accuracy, material properties, and computational requirements are significant barriers to and/or limitations for widespread implementation of AM processes. To mitigate these challenges, NIST program focuses on the problems associated with AM material characterization, real-time control of AM processes, qualification methodologies and system integration for AM. This presentation will summarize some metrology solutions for AM machines/feedstock materials, AM processes, and AM parts towards overcoming the challenges.
Mechanistic determinants of effector-independent motor memory encoding
Pratik MUTHA (Indian Institute of Techology). Invité par Fabrice SARLEGNA.
Coordinated, purposeful movements learned with one effector generalize to another effector, a finding that has important implications for tool use, sports, performing arts and rehabilitation. This occurs because the motor memory acquired through learning comprises components that are effector-independent. Despite knowing this for decades, the neural mechanisms and substrates that are causally associated with the encoding of effector-independent motor memories, remain poorly understood. Here we exploit inter-effector generalization, the behavioral signature of effector-independent memory representations, to address this crucial gap. We first show in healthy human participants that post-learning generalization across effectors is principally predicted by the level of an implicit mechanism that evolves gradually during learning and produces a temporally stable memory. We then demonstrate that interfering with left but not right posterior parietal cortex (PPC) using high-definition cathodal transcranial direct current stimulation impedes learning mediated by this mechanism, thus potentially preventing the encoding of effector-independent memories. We confirm this in our final experiment in which we show that disrupting left PPC but not primary motor cortex after learning has been allowed to occur, blocks inter-effector generalization. Collectively, our results reveal the key mechanism that encodes an effector-independent memory trace and uncover a central role for the PPC in its representation. Remarkably, the encoding of such motor memory components outside primary sensorimotor regions likely underlies a parsimonious neural organization that enables more efficient movement planning in the brain, independent of the effector used to act.
Vers des applications de l'imagerie polarimétrique pour la robotique mobile
Olivier MOREL (Laboratoire Electronique, Informatique et Image; Université de Bourgogne & CNRS). Invité par Julien SERRES.
La présentation traitera de mes principales activités de recherche autour de l'imagerie polarimétrique et de ses applications. L’imagerie polarimétrique est une technique permettant de représenter les informations de polarisation issues d’un objet ou d’une scène sous forme matricielle. Initialement dédiée à des applications d’analyse purement optique, elle s’est rapidement développée ces dix dernières années avec la mise sur le marché de caméras polarimétriques. Ces dernières permettent d’envisager des applications en robotique mobile car leur taille est devenue compacte et les informations de polarisation peuvent être exploitées en temps réel. Après avoir introduit quelques notions élémentaires, je présenterai les premières applications que nous avons développées en imagerie médicale sur l'analyse de mélanomes et sur la numérisation d'organes par laparoscopie. Puis je décrirai des applications orientées vers la vision avec le calibrage et l'utilisation de capteurs polarimétriques et omnidirectionnelles. Je terminerai mon exposé avec des applications dédiées à la robotique mobile avec l'analyse de scènes et l'estimation d'attitude par vision polarimétrique.
Bio :
Diplômé de l'école d'ingénieurs Polytech Savoie en 2001, Olivier Morel a obtenu un DEA en Informatique et Instrumentation de l'Image à l'Université de Bourgogne en 2002.
Il a soutenu sa thèse de doctorat en 2005 sur des travaux portant sur la reconstruction d'objets métalliques par imagerie polarimétrique. Il est depuis 2007, Maître de Conférences à l'Université de Bourgogne et ses travaux de recherche concernent principalement l'utilisation de l'imagerie non-conventionnelle : omnidirectionnelle, polarimétrique pour des applications en robotique mobile. De 2016 à 2018 il a coordonné le projet ANR VIPeR (VIsion Polarimétrique pour la navigation de Robots) qui a permis de développer cette thématique de recherche au sein de l'équipe ERL Vibot CNRS 6000.

Ant navigation.
Antoine WYSTRACH (Centre de Recherches sur le Comportement Animal – CNRS/Université Paul Sabatier, Toulouse ). Invité par Franck RUFFIER.
The remarkable navigational abilities of social insects are proof that small brains can produce exquisitely efficient, robust navigation in complex environments. Because social insects produce specialist foragers that are amenable to field and lab studies, they have been productive model systems for studies of navigation. Ideas derived from these studies of insect navigation have shown how simple mechanisms can produce robust and seemingly complex behaviour. I show here how simple low-resolution panoramic views, without the need for cognitive processes such as object identification or labelling provides an elegant solution to cope with the complexity of the world. Recent insect navigation research has only been possible because of techniques enabling the recording of visual scenes from the perspective of the insect. Without such techniques one has to intuit an animal’s point of view (its Umwelt) and I discuss how this may lead to unhelpful assumptions about the cues available for navigation. In the future, ants running on a track ball in front of screens displaying ecological environments may provide a powerful tool to understand how complex behaviours can emerge from the interaction between brain, body and environment.
Post-scriptum :
Antoine Wystrach obtained his licence in biology in Caen, with a special focus on neuroscience and ecology. He then went to Paris 13 University for a master in Ethology, where animal behaviour is studied at the crossroad between ecology, neuroscience and psychology. AW started his own research project on ant visual navigation and realised a PhD combining lab (in the university of Toulouse Paul Sabatier) and field experiments in Australia (with Macquarie university). He then obtained 2 years founding from the the Fyssen Foundation to pursue his research on ant navigation in Sussex University, with a stronger focus on modelling. AW then went at the University of Edinburgh involved in a European project with the aim of modelling the neural mechanisms underpinning learning in drosophila larvae. He pursues in the mean time his research on ant navigation by collaborating with his previous lab in Sussex and Macquarie Universities. Beyond the field of insect navigation, AW’s research shows how apparently complex behaviours can arise from surprisingly simple explanations, and thus has an impact in the field of comparative cognition.

International Workshop in AgingThe workshop has took place in Marseille, at the Faculty of Sport Sciences located on the campus of Luminy - (163 Avenue de Luminy, 13288 – Marseille).
The human organism is a complex system composed of a huge number of sub-systems that interact on different scales of space and time. It is now accepted that aging is more than the sum of the separate alterations occurring across the multiple subsystems. Instead, aging leads to critical changes in the functional interactions that occur within and between them.
