Benchmarking the sustainable manufacturing paradigm via automatic analysis and clustering of scientific literature: A perspective from Italian techno…
2019
Abstract The number of scientific papers in the field of Sustainable Manufacturing (SM) shows a strong growth of interest in this topic in the last 20 years. Despite this huge number of publications, a clear statement of the profound meaning of Sustainable Manufacturing, or at least a strong theoretical support, is still missing. The 6R framework seems to be a first attempt to rationalize this issue, as it is an axiomatic identification of its true nature. Recognizing the pursuing of one or more of the Reduce-Recycle-Reuse-Recover-Redesign-Remanufacture principles allows users to identify if any manufacturing action is in the right direction of sustainability. In the paper, the authors spec…
A Multilayered Plate Theory with Transverse Shear and Normal Warping Functions
2016
A multilayered plate theory which takes into account transverse shear and normal stretching is presented. The theory is based on a seven-unknowns kinematic field with five warping functions. Four warping functions are related to the transverse shear behaviour, the fifth is related to the normal stretching. The warping functions are issued from exact three-dimensional solutions. They are related to the variations of transverse shear and normal stresses computed at specific points for a simply supported bending problem. Reddy, Cho-Parmerter and (a modified version of) Beakou-Touratier theories have been retained for comparisons. Extended versions of these theories, able to manage the normal s…
El fomento de la mediación y de otros medios alternativos de justicia (también) en relación con la sustracción internacional de menores en Europa
2021
El decidido fomento de la mediación y de otros instrumentos MASC en el ámbito del Derecho de familia internacional constituye una constante, en los últimos tiempos, en el panorama comparado internacional. También en relación con aquellas disputas que involucran a menores. La UE no es ajena a este proceso y contribuye decididamente a éste. Aunque persisten dudas sobre la virtualidad real de estos mecanismos en la práctica diaria internacional.
Different approaches to marriage downgrading : from an anti-elusive measure to an antidiscriminatory claim
2021
The essay focuses on the different mechanisms of marriage downgrading. Given the principle of ?cross-border continuity? of statuses, limits to this continuity are sometimes admitted and they are placed through downgrading mechanisms. That can occour in the case of same-sex marriages transcription in a Member State which does not allow such marriages, but which does allow samesex registered partnerships. Downgrading mechanism has an anti-elusive function, but it is not without problems in terms of discrimination on the grounds of sexual orientation. A different approach is taken in the case of an opposite-sex couple requesting the downgrading of their marriage, celebrated before the Member S…
Protection of the surviving spouse in French law
2021
While French inheritance law has recently sought to give everyone more freedom to anticipate the transmission of their estate, it still guarantees to the children a reserved portion in his estate. This guarantees the deceased?s children a minimum share in his/her estate. However, the mechanisms protecting this reserve are subject to legal adjustments when spouses wish to organize the protection of the couple?s survivor, either by submitting to a conventional matrimonial regime or by giving themselves gifts that improve the legal succession of the spouse. This ensures a balance between the protection of the spouse and that of the compulsory heirs. Not seeming to be satisfied, several famous …
Los programas de cumplimiento penal : Aspectos generales
2021
In Spain, as in many other countries, corporate criminal liability has been a reality for years, as well as criminal compliance programs that allow them to be mitigated or exonerated from liability. In this article we will present some of the main keys to consider for the implementation of these mechanisms. This is a series of general considerations that can serve as a guide to understand the complex system of crime prevention provided by the organization and management models in the corporate environment.
Un cuento de robots : La hija cibernética de descartes
2021
French philosopher René Descartes is today valued as a forerunner of the studies of human mind, artificial intelligence and robotic systems. Throughout his work there are large references to automata and the possibility of artificial life, as well as an assessment of the differences between rational behavior of human beings and the purely mechanical of animals and automata. In addition to these references, there is a fable about the creation by the philosopher of an automaton that replicated his deceased daughter Francine, a story that is well known among the French and Anglo-Saxon specialists, but not so much in the Spanish ones, which is what settles this short work
Radio environment map estimation based on communication cost modeling for heterogeneous networks
2017
Los mapas del entorno radioeléctrico pueden ser una poderosa herramienta para lograr una asignación de recursos eficiente y consciente del contexto en las redes heterogéneas 5G. En este trabajo, consideramos una red heterogénea formada por una red celular tradicional y una red de sensores inalámbricos. El papel de la red de sensores inalámbricos es estimar el mapa del entorno radioeléctrico de la célula utilizando una técnica de interpolación geoestadística denominada Kriging. En un trabajo anterior se propuso un algoritmo de agrupación distribuida de sensores para reducir la complejidad de la estimación. En nuestra contribución, el proceso de formación de clústeres se modifica para incluir…
Distributed radio map reconstruction for 5G automotive
2018
Se espera que los mapas de entorno radio sean una herramienta esencial para la optimización y gestión de recursos del 5G en vehículos. En este trabajo, consideramos el problema de la reconstrucción del mapa de entorno radio utilizando una red de sensores inalámbricos formada por nodos sensores en vehículos, nodos de acceso de una infraestructura de ciudad inteligente, etc. Debido a las limitaciones de recursos en las redes de sensores, es crucial seleccionar un pequeño número de mediciones de los sensores para reconstruir el campo. En este contexto, presentamos un novedoso algoritmo distribuido basado en el método de regresión Kriging para la reconstrucción del mapa de entorno radio en térm…
Safety Evaluation of α-Lipoic Acid Supplementation: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Studies
2020
Alpha-lipoic acid (ALA) is a natural short-chain fatty acid that has attracted great attention in recent years as an antioxidant molecule. However, some concerns have been recently raised regarding its safety profile. To address the issue, we aimed to assess ALA safety profile through a systematic review of the literature and a meta-analysis of the available randomized placebo-controlled clinical studies. The literature search included EMBASE, PubMed Medline, SCOPUS, Google Scholar, and ISI Web of Science by Clarivate databases up to 15th August 2020. Data were pooled from 71 clinical studies, comprising 155 treatment arms, which included 4749 subjects with 2558 subjects treated with ALA an…
