Future memorie. L’ex ospedale psichiatrico di Palermo. Future memories. The former psychiatric hospital in Palermo
2017
La memoria dell’ex manicomio di Palermo ha un futuro. Il riuso del complesso può svelare alla comunità urbana vicende quotidiane di chi fu chiamato “pazzo”, monumenti, paradisi ipogei, altre tracce storiche e una nuova permeabilità dei percorsi cittadini. Il progetto per il Palazzo della Vignicella, elaborato, fra altri, in una ricerca PRIN, più che una risposta è un’esplorazione delle potenzialità dell’opera e un contributo alla conoscenza dei principi architettonici a questa sottesi. The memory of the former asylum in Palermo has a future. The reuse of the complex can reveal to the urban community the everyday life of who was called "mad" but also of the monuments, underground paradises, …
Memory and presence of thólos in architecture
2019
Il thòlos, architettura di pietra dall’origine antichissima (probabilmente greco-arcaica, quindi etrusca e poi romana) è diffuso nell’intero bacino mediterraneo in territori anche distanti (Grecia, Armenia, Cappadocia, Iran, Tunisia, Italia); la Sicilia ne conserva più di ogni altro (la Gurfa di Alia, nelle campagne interne dell’Isola, è la più grande del Mediterraneo) e, nel loro insieme, rappresentano la memoria di epoche mitiche e di personaggi favolosi come Dedalo. Nel loro insieme i thòloi costruiscono una trama di città invisibili in cui si coniugano strategie progettuali-costruttive che dall’antichità sono giunte sino a noi: quasi sempre scavate dentro montagne (luoghi di per sé sacr…
Standard mechanical testing is inadequate for the mechanical characterisation of shape-memory alloys: Source of errors and a new corrective approach
2022
Thanks to its unique behaviour characterised by a superelastic response, Nitinol has now become the material of preference in a number of critical applications, especially in the area of medical implants. However, the reversible phase transformation producing its exceptional comportment is also responsible for a number of phenomena that make its mechanical characterisation particularly complex, by hindering the assumptions at the very basis of common uniaxial tensile testing. This necessarily reduces the level of safety and design optimization of current applications, which rely on incorrect mechanical parameters. In this study, the spurious effects introduced by the unconventional material…
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…
A Cognitive Robotics Implementation of Global Workspace Theory for Episodic Memory Interaction with Consciousness
2023
Abstract—Artificial general intelligence revived in recent years after people achieved significant advances in machine learning and deep learning. This leads to the thinking of how real intelligence could be created. Consciousness theories believe that general intelligence is essentially conscious, yet no universal definition is agreed upon. In this work, Global Workspace Theory is implemented and integrated with crucial cognitive components. With the focus on episodic memory and inspiration from the nature of episodic memory in psychology and neuroscience, the episodic memory component is implemented within the Global Workspace framework. In our experiment, the robotic agent operates in a …
Pedestrian Tracking in 360 Video by Virtual PTZ Cameras
2018
Since the data acquired by a PTZ camera change while adjusting the pan, tilt and zoom parameters, the results of tracking algorithms are difficult to reproduce; such diffi- culty limits the development and the comparison of tracking algorithms with PTZ cameras. The recently introduced 360- degree cameras acquire spherical views of the environment, generally stored as equirectangular images. Each pixel of an equirectangular image corresponds to a point on the spherical surface. A gnomonic projection can be used to project the points on the spherical surface onto a plane tangent to the sphere. Such tangent plane can be interpreted as the image plane of a virtual PTZ camera oriented towards th…
A new algorithm for bit rate allocation in JPEG2000 tile encoding
2004
A new algorithm for allocating a given bit rate to different image tiles in the JPEG2000 encoding system is proposed. The algorithm outperforms other approaches commonly used in implementations. The new algorithm is suitable when information content is not equally distributed across the image. It is based on the computation of an index of the information content of each tile. To implement the proposed approach, we modified JasPer, a free software-based JPEG2000 coder implementation (Adams, M.D. and Kossentini, F., Proc. IEEE Int. Conf. on Image Process., vol.2, p.53-6, 2000). The experimentation was carried out on a subset of the JPEG2000 test images. Experimental results are reported, show…
In ricordo di Federicomaria Muccioli
2020
Un anno fa non avrei pensato di scrivere queste poche parole: sapevo che le condizioni di salute di Federico Muccioli erano peggiorate; lo sentivo anche dalla voce molto affaticata al telefono, ma aveva già superato momenti difficili e speravo che avrebbe visto l’uscita di questi Atti, magari a Palermo, città che ormai conosceva bene e con cui aveva stabilito anche una feconda intesa scientifica, grazie tra l’altro alla sua collaborazione con la nostra rivista ὅρμος. Ricerche di Storia antica...
Memory lost, memory regained. Considerations on the recovery of Sacred Texts in Messenia and in Biblical Israel: A Comparison
2013
The fourth book of Pausanias’ Periegesis may be read as an excursus in the collective memory of the Messenian people, condemned to almost 300 years of sorrowful diaspora after a conflict with the Spartans. According to the oracles, the possibility of a homecoming is linked to a small secret object, which, if properly kept, would guarantee the recovery of the lost land. Legend has it that this object was hidden in the mounts of Ithome by Aristomenes, the hero of the Messenian resistance against Sparta’s oppression and an expert of oracular knowledge. Many years later, a dream vision reveals to Epaminondas and to the military chief Epiteles the exact site where Aristomenes supposedly buried t…
Memory and Religion in the Greek World
2013
The necessity to build a common base of shared values on which to establish any type of social relationship and overcome the use of violence for the resolution of arguments has often found more effective answers drawing from the sacred sphere and its resources. With its complex verbal and gestural structure and its close connection with the other effective enunciated forms the oath is an instrument, both religious and political at the same time, which permits the preservation of the memory of the expressed affirmations and the commitments taken on. Thanks to the convergence of actions and words, both functional towards the creation of binding situations, the oath is a guarantee as much on t…
