Il testo propone un articolato commento alle posizioni teoriche e alle linee di ricerca progettuale espresse da Michele Argentino, professore ordinario di Design a Palermo circa la necessità di riconquistare il ruolo sociale alla creatività individuale, riprendendosi il desiderio di diventare nuovamente "Homo Faber". Il testo inoltre presenta gli obiettivi della nuova collana scientifica - diretta dall'autrice - dal Titolo " Design e Contesti": intercettare ambiti di ricerca trasversali alle discipline del progetto, favorire gli intrecci tra idee progettuali e percorsi di innovazione socio-culturale, sviluppare nuove strategie produttive compatibili con i diversi aspetti della sostenibilità.
The urban rent in the multicultural city: retail shops, migrants and urban decline in the historic centre of Palermo
2020
La diffusione di nuove modalità di vendita al dettaglio, come gli shopping mall, i megastore e l’e-commerce, hanno modificato i tradizionali modelli localizzativi di immobili a destinazione commerciale, incidendo anche sulle connotazioni del tessuto urbano ed extraurbano e sulla distribuzione spaziale della rendita. Anche le zone centrali delle città hanno subito trasformazioni significative, che a volte si traducono in un vero e proprio declino, soprattutto in presenza di sistemi economici locali deboli e di mercati immobiliari in recessione. Una quota rilevante di immobili a destinazione commerciale può rimanere a lungo non utilizzata per eccesso di offerta sulla domanda, poiché a fronte …
Forecasting energy output of a solar power plant in curtailment condition based on LSTM using P/GHI coefficient and validation in training process, a…
2022
This study presents how to improve the short-term forecast of photovoltaic plant's output power by applying the Long Short-Term Memory, LSTM, neural networks for industrial-scale solar power plants in Vietnam under possible curtailment operation. Since the actual output power does not correspond to the available power, new techniques (Global Horizontal Irradiance - GHI interval division, P/GHI factor addition (P - Power)) have been designed and applied for processing errors and missing data. The prediction model (LSTM network, structure of hidden layers, number of nodes) has been developed by the authors in a previous work. In this new version of the model, the training technique is improve…
An Intelligent Empowering Agent (IEA) to Provide Easily Understood and Trusted Health Information Appropriate to the User Needs
2023
AbstractMost members of the public, including patients, usually obtain health information from Web searches using generic search engines, which is often overwhelming, too generic, and of poor quality. Although patients may be better informed, they are often none the wiser and not empowered to communicate with medical professionals so that their care is compatible with their needs, values, and best interests. Intelligent Empowering Agents (IEA) use AI to filter medical information and assist the user in the understanding of health information about specific complaints or health in general. We have designed and developed a prototype of an IEA that dialogues with the user in simple language, c…
A genetic algorithm for the design of a fuzzy controller for active queue management
2003
Active queue management (AQM) policies are those\ud policies of router queue management that allow for the detection of network congestion, the notification of such occurrences to the\ud hosts on the network borders, and the adoption of a suitable control\ud policy. This paper proposes the adoption of a fuzzy proportional\ud integral (FPI) controller as an active queue manager for Internet\ud routers. The analytical design of the proposed FPI controller is\ud carried out in analogy with a proportional integral (PI) controller,\ud which recently has been proposed for AQM. A genetic algorithm is\ud proposed for tuning of the FPI controller parameters with respect\ud to optimal disturbance rej…
Les détails archéologiques dans les décorations monumentales des bâtiments publics siciliens du XXe siècle : une recherche d’identité
The intervention presented a premise aimed at reconstructing the Greek and Roman past of Sicily, the importance of the archaeological heritage rediscovered during the years of the Grand Tour and the archaeological excavation campaigns between the 18th and early 20th centuries. Subsequently, the presence of «archaeological» details or at least attributable to Greek and Roman classical art and architecture in the monumental decorations of Sicilian public buildings of the 20th century was analyzed, focusing on the period of the fascist regime. Fascist ideology, inspiration from the Roman past for the constitution of the «Third Rome» and references to it in periodicals and Italian architectural…
Logical Operations among Conditional Events: theoretical aspects and applications
2019
We generalize the notions of conjunction and disjunction of two conditional events to the case of $n$ conditional events. These notions are defined, in the setting of coherence, by means of suitable conditional random quantities with values in the interval $[0,1]$. We also define the notion of negation, by verifying De Morgan's Laws. Then, we give some results on coherence of prevision assessments for some families of compounded conditionals and we show that some well known properties which are satisfied by conjunctions and disjunctions of unconditional events are also satisfied by conjunctions and disjunction of conditional events. We also examine in detail the coherence of the prevision a…
On compound and iterated conditionals
2021
We illustrate the notions of compound and iterated conditionals introduced, in recent papers, as suitable conditional random quantities, in the framework of coherence. We motivate our definitions by examining some concrete examples. Our logical operations among conditional events satisfy the basic probabilistic properties valid for unconditional events. We show that some, intuitively acceptable, compound sentences on conditionals can be analyzed in a rigorous way in terms of suitable iterated conditionals. We discuss the Import-Export principle, which is not valid in our approach, by also examining the inference from a material conditional to the associated conditional event. Then, we illus…
Sequentially Forecasting Economic Indices Using Mixture Linear Combinations of EP Distributions
2021
This article displays an application of the statistical method moti- vated by Bruno de Finetti's operational subjective theory of probability. We use exchangeable forecasting distributions based on mixtures of linear com- binations of exponential power (EP) distributions to forecast the sequence of daily rates of return from the Dow-Jones index of stock prices over a 20 year period. The operational subjective statistical method for comparing distributions is quite different from that commonly used in data analysis, because it rejects the basic tenets underlying the practice of hypothesis test- ing. In its place, proper scoring rules for forecast distributions are used to assess the values o…
Quasi conjunction and p-entailment in nonmonotonic reasoning
2010
We study, in the setting of coherence, the extension of a probability assessment defined on n conditional events to their quasi conjunction. We consider, in particular, two special cases of logical dependencies; moreover, we examine the relationship between the notion of p-entailment of Adams and the inclusion relation of Goodman and Nguyen. We also study the probabilistic semantics of the QAND rule of Dubois and Prade; then, we give a theoretical result on p-entailment.
