Enhancing the Iterative Smoothed Particle Hydrodynamics Method
2021
Motivated by recent research on the iterative approach proposed for the smoothed particle hydrodynamics (ISPH) method, some ideas to improve the process are introduced. The standard procedure is enhanced iterating on the residuals preserving the matrix-free nature of the process. The method is appealing providing reasonable results with disordered data distribution too and no kernel variations are needed in the approximation. This work moves forward with a novel formulation requiring a lower number of iterations to reach a desired accuracy. The computational procedure is described and some results are introduced to appreciate the proposed formulation.
Microalgae-bacteria consortia for urban wastewater treatment
2021
Los consorcios de microalgas y bacterias surgen como una opción idónea en el marco de las tecnologías sostenibles para el tratamiento de aguas residuales. Los mecanismos de eliminación de contaminantes son el resultado de interacciones ecológicas directas y/o indirectas entre las microalgas y las bacterias autóctonas de las aguas residuales. Para diseñar sistemas eficaces que incorporen consorcios de microalgas y bacterias es necesario comprender las interacciones ecológicas entre ambas comunidades dentro de los procesos de tratamiento de aguas residuales. El objetivo principal de este trabajo de investigación es, por tanto, estudiar y explorar las interacciones ecológicas para mejorar el t…
L'écart et l'entre-deux : traduire la culture
2011
Comparative linguistics seems to suggest that the gap between two languages can be filled by grammar. But mapping the structural gaps between languages hardly makes for the more fundamental gap that is created by the writing of a new text, a supposedly identical addendum to the first. Writing that new text entails questions about the nature of texts, their intentions, their interpretations. Translation must therefore develop a hermeneutical approach. This critical stance is about sorting out what belongs to the languages and what belongs to the text as a specific unit, as a cultural and authorial unit. Because of its cultural nature, translation questions the way one can carry meaning acros…
Identification of Energy Hubs for the Exploitation of Residual Biomass in an Area of Western Sicily
2017
Recent years have witnessed a marked reduction in financial incentives for renewable energy production in Italy as a consequence of the fact that the nation has already reached its energy policy targets for 2020, However, incentives still persist in certain sectors, such as those of specialized crops for biomass and residual biomass. In order to increase use-efficiency of biomass resources, careful study is needed of their characteristics, and their distribution within an area and over time: biomass use is of interest when production is concentrated in a given area and sufficiently available throughout the year. In order to assess the competitiveness of the biomass energy sector, the logist…
