    In-situ monitoring of image texturing via random forests and clustering with applications to additive manufacturing

    The amount of attention paid to in-situ monitoring in Additive Manufacturing (AM) has significantly increased over the last few years, paving the way to a paradigm shift for quality monitoring and control via big data analysis of signals, images, and videos. In-situ quality monitoring represents an opportunity for waste reduction and first-time-right production via inline detection of process flaws, which allows early identification of scraps and the possibility of correcting actions for first-time-right production. This article presents a solution for in-situ monitoring of images taken layerwise in material extrusion AM. Compared with the existing solutions, mainly focusing on monitoring the shape deviation observed at each layer with respect to the nominal shape, this article focuses on monitoring the internal surface texture with the aim of detecting over- and under-extrusion flaws. Inspired by an approach reported in the literature that was developed for textile image monitoring, we propose a solution for in-situ monitoring of textured surfaces which is based on combining Random Forests with clustering to automatically identify defective locations layerwise. A real case study based on Fused Filament Fabrication is used to compare the performance of the novel proposed solution with the original one and identify an appropriate direction for future research

    Attraverso l’approfondita analisi dei taccuini e dei diari di viaggio manoscritti di Maria Luisa Gengaro, l’autore pone in evidenza il rigore e la passione con cui l’insigne storica dell’arte promuoveva la conoscenza e lo studio del patrimonio artistico presso i suoi studenti liceali, nel difficile anno 1942. In chiusura del saggio sono inoltre riportati alcuni passi salienti relativi agli appunti di viaggio redatti in forma dattiloscritta dagli studenti del Liceo Parini di Milano, anch’essi conservati all’interno del Fondo Gengaro. Notebooks and travel diaries in the archivial collection Maria Luisa Gengaro, preserved by ISAL The author analyses the notebooks and travel diaries manuscripts by Maria Luisa Gengaro, and describes the rigor and passion with which the eminent art historian promoted the understanding and study of the artistic heritage to her high school students, in the difficult year 1942. In closing, the essay also proposes some salient passages about a travel made by students of Liceo Parini in Milan in typewritten form,conservated in the Fondo Gengar

    System architecture

    Solution Oriented Partnership is about the conception and development of solutions. More precisely: it is about industrialised, contextualised, sustainable solutions that are produced and delivered by networks of partners: the solution-oriented partnerships. It is also about a new idea of industrialization: an advanced industrialization with the capacity to bring a multiplicity of players together to collaborate in an effective way, with a view to sustainable objectives. The book is organised in two parts: Themes, that discusses the nature of partner-based solutions, and Tools, that introduces methodological tools for their conception and development. “System Architecture” is a chapter of the Themes and is focused on the ways to define system rules able to assure flexibility on one side and industrial production processes on the other side. Partner-based solutions arises from the activity of a group of research centres and European enterprises, funded under the European Community 5th Framework Programme. This research, known as HiCS, Highly Customerised Solutions, coordinated by the author Luisa Collina, was an action research, the specific subject of which has been “food for people with reduced mobility”

    Il saggio segnala l’importanza delle carte del Fondo Maria Luisa Gengaro, conservato negli Archivi ISAL, per la critica dell’arte e per il contesto culturale milanese tra le due guerre. Dopo una sintesi su consistenza e storia del fondo archivistico, l’autore analizza l’impegno eccezionale della studiosa nell’insegnamento della storia dell’arte, al liceo e all’università, accennando anche ai suoi rapporti professionali e amicali, in particolare con Paolo D’Ancona e Giuseppe Antonio Borgese. Viene ricordato il suo signifi cativo impegno per la tutela del patrimonio architettonico e artistico di Milano e provincia durante i bombardamenti della seconda guerra mondiale. Le carte personali e il diario, redatto tra il 1942 e 1975, lasciano trasparire l’umanità ricca e sensibile, capace di intensità poetica, della studiosa dei codici miniati dell’Ambrosiana. The archival Fund Maria Luisa Gengaro in ISAL The text underlines the importance of the documents of the Maria Luisa Gengaro Fund - that is preserved in the ISAL Archives - for the art criticism and the intellectual context in Milan in the period between the World Wars. After a ynthesis about the Fund’s texture and history, the article analyzes the incredible involvement of Gengaro in her activity, teaching history of art in the high school and at the university, and it mentions even the relationships and friendships with Paolo D’Ancona and Giuseppe Antonio Borgese. Th e Author of the article mentions the meaningful involvement of Gengaro for the wardship of the architectural and artistic heritage of Milan and its province during the bombing of the II World War. Th e personal documents and the diary, written between 1942 and 1975, reveal the reach and sensitive humanity of the Ambrosiana’s illuminated manuscript scholar

    Host-defense peptides: from biology to therapeutic strategies

    No full text
    Primitive innate defense mechanisms in the form of gene-encoded antimicrobial peptides are now considered as potential candidates for the development of new therapeutics. They are well known for their function as the first protective barrier of all organisms against microbial infections. In addition, emerging studies reveal that they assist in modulating the host immune system. The biological properties of these host-defense peptides, their role in human health, their cell selectivity and related molecular mechanisms are discussed in this multi-author review along with the strategies to transform them or their peptidomimetics into clinically usable drug

    La riforma della prescrizione tra diritti dell’imputato e della persona offesa: riflessioni dal punto di vista della Convenzione europea dei diritti dell’uomo

    The article addresses the reform of the statute of limitations in light of the case law of the European Court of Human Rights. After discussing the role played by the statute of limitations in civil and criminal proceedings, the author specifically focuses on the questions relating to the reasonable duration of trials and to the need to balance the rights of the victim and those of the accused person. The author rules out the possibility of using the statute of limitations as a ‘compensation’ for possible infringements on the principle of reasonable duration of proceedings. She also maintains that the Strasbourg case-law should not be used as a systematic reference framework for the reform of the statute of limitation

    Un frammento di Timocle comico

    No full text
    The author inquires the question about the dramatic nature of Timocle’s Ikarioi Saturoi, a question much discussed by the classical scholarship of the nineteenth and twentieth century. The new reading of fr. 18 K.-A., handed down from Athenaeus, discloses exact correspondences, concerning language and performance, with Eupoli’s Demoi and, above all, with Aristofane’s Ploutos, so that it’s possible to lean to the opinion that the work has comic, and not satyrical, nature
