    Understanding and Tuning Mass-Interaction Networks Through Their Modal Representation

    No full text
    International audienceSound is all about vibration, and the GENESIS environment provides an efficient way for modeling and simulating complex vibrating structures, enabling to produce rich sounds. In this paper, we propose an overview of tools recently developed and available within the GENESIS environment, allowing a better understanding on how mass-interaction networks behave and introducing some enhanced tuning of their vibrating properties. All these tools try to address an inherent need of any creative process either in the physical world or in GENESIS, which is to create bidirectional connections between properties of a phenomenon, in our case, audible sounds, and properties of what produced it, here, mass-interaction networks. For this purpose, we will introduce the topological and modal representations of such mass-interaction networks and appreciate how relevant it can be to switch between these different representations to really apprehend its inner properties and those of the sounds it produces

    Recent developments in high-throughput technologies have accelerated the accumulation of massive amounts of omics data from multiple sources: genome, epigenome, transcriptome, proteome, metabolome, etc. Traditionally, data from each source (e.g., genome) is analyzed in isolation using statistical and machine learning (ML) methods. Integrative analysis of multi-omics and clinical data is key to new biomedical discoveries and advancements in precision medicine. However, data integration poses new computational challenges as well as exacerbates the ones associated with single-omics studies. Specialized computational approaches are required to effectively and efficiently perform integrative analysis of biomedical data acquired from diverse modalities. In this review, we discuss state-of-the-art ML-based approaches for tackling five specific computational challenges associated with integrative analysis: curse of dimensionality, data heterogeneity, missing data, class imbalance and scalability issues

    Vibration control in plates by uniformly distributed PZT actuators interconnected via electric networks

    Full text link
    In this paper a novel device aimed at controlling the mechanical vibrations of plates by means of a set of electrically-interconnected piezoelectric actuators is described. The actuators are embedded uniformly in the plate wherein they connect every node of an electric network to ground, thus playing the two-fold role of capacitive element in the electric network and of couple suppliers. A mathematical model is introduced to describe the propagation of electro-mechanical waves in the device; its validity is restricted to the case of wave-forms with wave-length greater than the dimension of the piezoelectric actuators used. A self-resonance criterion is established which assures the possibility of electro-mechanical energy exchange. Finally the problem of vibration control in simply supported and clamped plates is addressed; the optimal net-impedance is determined. The results indicate that the proposed device can improve the performances of piezoelectric actuationComment: 22 page
