    Non-linear Quantization of Integrable Classical Systems

    Full text link
    It is demonstrated that the so-called "unavoidable quantum anomalies" can be avoided in the farmework of a special non-linear quantization scheme. A simple example is discussed in detail.Comment: LaTeX, 14 p

    Discretization of Information Collecting Situations and Continuity of Compensation Rules

    Get PDF
    A canonical procedure is described, which associates to each infinite information collecting situation a related information collecting situation with finite state and action spaces, in such a way that the two corresponding IC-games are near to each other.Compensations for informants are then also near to each other in the two IC-situations, if they are based on continuous compensation rules.cooperative games;information

    Il DM 93/2017 sui controlli degli strumenti di metrologia legale

    Get PDF
    Questo articolo analizza il recente Decreto Ministeriale che disciplina le verifiche periodiche sugli strumenti di misura impiegati in metrologia legale. Vengono discussi gli aspetti giuridici e metrologici, e si mostra come la palese mancanza di competenze metrologiche con cui sono stati redatti gli allegati tecnici rischi seriamente di compromettere e vanificare tutto ciò che di buono è stato introdotto, dal punto di vista specificatamente giuridico, in questo delicato settore

    Time-resolved photoluminescence of n-doped SrTiO_3

    Full text link
    Following the recent surge of interest in n-doped strontium titanate as a possible blue light emitter, a time-resolved photoluminescence analysis was performed on nominally pure, Nb-doped and oxygen-deficient single-crystal SrTiO3 samples. The doping-effects on both the electronic states involved in the transition and the decay mechanism are respectively analyzed by comparing the spectral and dynamic features and the yields of the emission. Our time-resolved analysis, besides shedding some light on the basic recombination mechanisms acting in these materials, sets the intrinsic bandwidth limit of the proposed blue light emitting optoelectronic devices made of Ti-based perovskites heterostructures in the GHz range

    Towards explainable face aging with Generative Adversarial Networks

    Get PDF
    Generative Adversarial Networks (GAN) are being increasingly used to perform face aging due to their capabilities of automatically generating highly-realistic synthetic images by using an adversarial model often based on Convolutional Neural Networks (CNN). However, GANs currently represent black box models since it is not known how the CNNs store and process the information learned from data. In this paper, we propose the \ufb01rst method that deals with explaining GANs, by introducing a novel qualitative and quantitative analysis of the inner structure of the model. Similarly to analyzing the common genes in two DNA sequences, we analyze the common \ufb01lters in two CNNs. We show that the GANs for face aging partially share their parameters with GANs trained for heterogeneous applications and that the aging transformation can be learned using general purpose image databases and a \ufb01ne-tuning step. Results on public databases con\ufb01rm the validity of our approach, also enabling future studies on similar models
