    A copula based BINAR(1) process with applications

    No full text
    The application of the simple first order integer-valued autoregressive model to multidimensional space allows the simultaneous modelling of multiple series. Despite this, existing models do not provide a great deal of flexibility for modelling dependence, allowing only positive correlations to be modelled. A copula is one of the most widely used tools in statistics to describe, analyze and model the relationship between random variables. As part of this study, we investigate a bivariate first order integer-valued autoregressive process in which cross-correlations are introduced through the use of copulas for the specification of the joint distribution of innovations. Throughout the paper, we emphasize the parametric case arising from the Poisson extended exponential marginals. An empirical illustration is provided using a bivariate financial time series and a bivariate criminal dataset

    eXplainable artificial intelligence for non-visual multiclass recognition of EHDA Modes

    Electrohydrodynamic atomization (EHDA) is a versatile technology applied to different fields ranging from process industries to materials science and medicine. Depending on the operating conditions, EHDA provides different spray modes, which are mostly recognized either by highspeed imaging or, less frequently, by current measurements. While high-speed imaging is very successful for lab experiments, it may be difficult to apply in field applications with limited optical access to the spray. To this scope, this study specifically uses frequency-domain analysis of emitted electric current signal data to propose an eXplainable Artificial Intelligence (XAI)-based approach for multi-class recognition of EHDA modes, improving the accuracy of electric current-based classification and allowing an online control of the spray performances. To this scope, a new dataset of experimental data for various liquid types with different chemical-physical properties has been built. The dataset is used to tune the XAI-based method through a supervised learning approach. By combining advanced feature engineering and a one-dimensional convolutional neural network (1D-CNN), the proposed approach achieves accurate classification, making possible the identification of dripping, intermittent, cone-jet, and the challenging multi-jet modes, without the need for visual data. The use of post-hoc XAI techniques ensures transparency, confirming that the model bases its decisions on frequency patterns aligned with the physics of the process. The proposed method demonstrates robustness and a certain adaptability, being capable of classifying with appreciable accuracy EHDA modes for liquids with physical properties different from those used for its training, marking a significant advancement in EHDA process control. This innovation lays the foundation for integrating AI-based classification into closed-loop systems for real-time optimization, addressing both academic and industrial challenges in process efficiency and automation

    87Sr/86Sr isotope ratios in soils, vine leaves, grapes and wines of the Italian volcanic districts authenticate their respective terroirs

    Interest in the origin and traceability of agri-food products has led to an increasing number of publications using strontium isotope ratios as a geographic tracer. We used 87Sr/86Sr isotope systematics to authenticate the provenance of wine from different volcanic districts of Italy. Samples of soil, grapes, leaves and bottled wines from 6 different wineries were analysed. A detailed study of the different soil horizons from the Somma-Vesuvio area demonstrates the relationship between the 87Sr/86Sr of the soils and the different parts of the grapevine (root, steam, grape, grape pulp, grape seed, grape skin), and the soil characteristics (soil type, granulometry, root density) that control the 87Sr/86Sr of the end-products. Results showed that the geological characteristics of volcanic terranes of Italy, and in particular the northwest to southeast 87Sr/86Sr gradient, are inherited by the wines of each region, such that the wines can be discriminated and authenticated by their isotope ratio
