    Project: ANR | IDEXLYON (ANR-16-IDEX-0005)

    International audience; Diffusing a graph signal at multiple scales requires computing the action of the exponential of several multiples of the Laplacian matrix. We tighten a bound on the approximation error of truncated Chebyshev polynomial approximations of the expon...

    Project: ANR | SOLHARIS (ANR-19-CE46-0009)

    International audience; Sparse direct solvers using Block Low-Rank compression have been proven efficient to solve problems arising in many real-life applications. Improving those solvers is crucial for being able to 1) solve larger problems and 2) speed up computations...

    International audience; When indexing large collections of short-read sequencing data, a common operation that has now been implemented in several tools (Sequence Bloom Trees and variants, BIGSI,.) is to construct a collection of Bloom filters, one per sample. Each Bloo...

    Project: ANR | SolDuGri (ANR-14-CE22-0019)

    International audience; In this paper we present the results of the national French project SolDuGri dealing with pavement reinforcement by glass fiber grids. In this project, an accelerated pavements test (APT) was performed on 6 pavement sections to evaluate the in si...

    Project: ANR | DISCONT (ANR-17-CE25-0005)

    International audience; Cyber-Physical Systems (CPSs) are multi-component systems that interact with the real world. Their heterogeneous nature makes them particularly difficult to model and prove. Our work proposes a framework allowing to design complex hybrid systems ...

    Project: ANR | PERCERA (ANR-16-CE28-0003)

    International audience; Recent evidence in adults indicates that object perceptual processing is affected by the competition between action representations. In the absence of specific motor plan, reachable objects associated with distinct structural (grasping) and funct...

    When humans interact with each other, collaborating on a shared activity or chatting, they are able to tell whether their interaction is going well or not and if they observe that its quality is deteriorating, they can adapt their behavior or invite their partner to act...

    We study the collective dynamics of two distant magnets coherently coupled by acoustic phonons that are transmitted through an intercalated crystal. By tuning the ferromagnetic resonances of the two magnets to an acoustic resonance of the crystal, we control a coherent ...

    International audience; Given a plant whose trajectories of interest remain in a known compact set and an associated observer, we propose a general framework to modify this observer so that its state remains in a given convex set for all times, without altering the obse...
