Type-2 Fuzzy Control of a Bioreactor
2009
Abstract—In this paper the control of a bioprocess using an adaptive type-2 fuzzy logic controller is proposed. The process is concerned with the aerobic alcoholic fermentation for the growth of Saccharomyces Cerevisiae a n d i s characterized by nonlinearity and parameter uncertainty. Three type-2 fuzzy controllers heve been developed and tested by simulation: a simple type-2 fuzzy logic controller with 49 rules; a type-2 fuzzyneuro- predictive controller (T2FNPC); a t y p e -2 selftuning fuzzy controller ( T2STFC). The T2FNPC combines the capability of the type-2 fuzzy logic to handle uncertainties, with the ability of predictive control to predict future plant performance making use of a…
How the Context Matters. Literal and Figurative Meaning in the Embodied Language Paradigm
2014
The involvement of the sensorimotor system in language understanding has been widely demonstrated. However, the role of context in these studies has only recently started to be addressed. Though words are bearers of a semantic potential, meaning is the product of a pragmatic process. It needs to be situated in a context to be disambiguated. The aim of this study was to test the hypothesis that embodied simulation occurring during linguistic processing is contextually modulated to the extent that the same sentence, depending on the context of utterance, leads to the activation of different effector-specific brain motor areas. In order to test this hypothesis, we asked subjects to give a moto…
Climatology of the aerosol extinction-to-backscatter ratio from sun-photometric measurements
2010
The elastic lidar equation contains two unknown atmospheric parameters, namely, the particulate optical extinction and backscatter coefficients, which are related through the lidar ratio (i.e., the particulate-extinction-to-backscatter ratio). So far, independent inversion of the lidar signal has been carried out by means of Raman lidars (usually limited to nighttime measurements), high-spectral-resolution lidars, or scanning elastic lidars under the assumption of a homogeneously vertically stratified atmosphere. In this paper, we present a procedure to obtain the lidar ratio at 532 nm by a combined Sunphotometer– aerosol-model inversion, where the viability of the solution is largely reinf…
Aerosol Lidar Intercomparison in the Framework of SPALINET—The Spanish Lidar Network: Methodology and Results
2009
Abstract—A group of eight Spanish lidars was formed in order to extend the European Aerosol Research Lidar Network–Advanced Sustainable Observation System (EARLINET-ASOS)project. This study presents intercomparisons at the hardware and software levels. Results of the system intercomparisons are based on range-square-corrected signals in cases where the lidars viewed the same atmospheres. Comparisons were also made for aeros backscatter coefficients at 1064 nm (2 systems) and 532 nm (all systems), and for extinction coefficients at 532 nm (2 systems). In total, three field campaigns were carried out between 2006 and 2007. Comparisons were limited to the highest layer found before the free tr…
Bello e Idea nell’estetica del Seicento
2007
The Beautiful and The Idea in 17th-Century Aesthetics In his renowned lecture on the Idea, which he delivered at the Academy of Saint Luke in 1664, Giovan Pietro Bellori asserts the superiority of ideal beauty against the slavish imitation of reality and the unbridled freedom of the imagination. However, an equally important, albeit lesser known, contributor to the formulation of this classicist aesthetic theory is Giovan Battista Agucchi, author of a Treatise on Painting that appeared in fragmentary form in 1646. In this work, Agucchi identifes beauty as the truest and highest aim of painting; he attributes to the artist the power to contemplate the Idea, and confers a profound cognitive v…
Arte e Idea. Francisco de Hollanda e l’estetica del Cinquecento
2004
Art and Ideas Francisco de Hollanda and Sixteenth-Century Aesthetics The historians of aesthetics who have studied the problem of ideas in art theory (from Panofsky to Baeumler and Tatarkiewicz) have overlooked Da pintura antiga, by Portuguese artist and theoretician Francisco de Hollanda (1517-1584), a text where the Platonic notion of idea enters a treatise on art for the first time. The present volume aims to fill such gap by shedding light on an author who has long been overshadowed by the great Michelangelo (whom Hollanda met during his stay in Rome in the years 1538-1540), as well as by advancing an analysis of the aesthetic concepts that emerge not only from Da pintura antiga, but fr…
A parody of action : Politics and pantomime in Agamben's critique of Arendt

The impurity of praxis : Arendt and Agamben
2023
AbstractIf politics is understood as a foundational and open-ended activity, a general problem that arises from such a framing concerns the question of how to sustain the possibility of continuous openings without converting action into permanence and closure. In this article, we approach this problematic by treating Hannah Arendt as an exemplary figure in the current of political thought that emphasizes the indeterminate nature of action. We focus more specifically on how Arendt addressed the question of sustaining action by exploring the role of forgiveness, promises, divided power, and principles of action in her thought. While we show that the task of sustaining the indeterminacy of act…
Tra cielo e terra. La figura dell’artista nel Rinascimento
2012
Nella figura del genio romantico, oltre alla metafora rinascimentale dell’artista–dio (già ampiamente scandagliata), convergono anche altri modelli teorici. Uno di questi attinge alla categoria della feritas, quale dimensione sotto certi aspetti sub umana – se per misurare l’humanitas consideriamo il parametro della ratio – ma al contempo più ampia e più ricca per le suggestioni provenienti dalla sfera dei sensi, dell’istinto e della passione. In questo lavoro si cerca di delineare come la “bestializzazione”, ovvero la degenerazione dei comportamenti umani a uno stato selvatico, costituisca una chiave di lettura per mettere a fuoco le dinamiche simboliche che convergono a delineare l’identi…
On the abnormal structure of finite groups
2014
We study finite groups in which every maximal subgroup is supersoluble or normal. Our results answer some questions arising from papers of Asaad and Rose.
