Disegni e incisioni di Tarquinio Ligustri da Viterbo conservati presso collezioni private e pubbliche italiane, francesi e tedesche
2021
In international, Italian, French and German public collections, but also among private collections, there are architectural drawings by the quadrature painter Tarquinio Ligustri da Viterbo, made after 1596 and depicting portals of his invention. This corpus is mostly unpublished and has remained anonymous for centuries. It consists of a consistent body of preparatory drawings kept at the Kunstbibliothek in Berlin, and a small number of engravings made from them, distributed in loose form but also bound in a rare miscellaneous volume published in the second half of the seventeenth century by Giovanni Giacomo De Rossi‘s famous Roman printing house Alla Pace. The detailed examination of the d…
Memoria, disinganno, composizione: Goethe, Kniep e la funzione del disegno durante il viaggio in Sicilia
2018
This article focuses on Goethe’s specific concept of drawing as it appears to the reader through the pages of his Italian journey. A fundamental role is played in this discourse by Christoph Heinrich Kniep, a young German draughtsman who has been recommended to Goethe by his friend, the painter Tischbein, and who accompanied the poet during his trip to Sicily. The key function of Kniep’s linear drawings was to create a visual archive destined to keep memory of his experience for future times, free from picturesque effects and potentially capable to force the recipient’s imagination. The relationship between the two travellers turned into a kind of creative symbiosis as can be seen from Goet…
I marginalia di Dino Buzzati: schemi, illustrazioni e disegni
2022
Secondo questa proposta di lettura dell'opera grafica di Dino Buzzati, che può essere estesa anche ad altri autori dal doppio talento, i disegni ai margini della scrittura possono essere interpretati allora nella loro funzione di relazione tra le arti che si risolve in una interazione, una negoziazione, uno slittamento oppure un conflitto, una cancellatura. Inoltre le annotazioni ai margini della scrittura, soprattutto nelle loro versioni grafiche, costituiscono una forma di introspezione autobiografica assai preziosa per ricostruire il profilo del loro autore, se scrittore e disegnatore al contempo.
Una dama dell'architettura a Palermo
2020
Questo saggio riguarda l’attività di una donna che può essere considerata una delle prime protagoniste e probabilmente, parafrasando Nikolaus Pevsner, una delle prime pioniere del Movimento Moderno a Palermo, un contesto culturale complesso. Il difficile ruolo della donna nell’architettura italiana degli anni ’60 e ’70, proveniente dai retaggi del regime fascista, è stato particolarmente palese in Sicilia dove l’attività professionale era soltanto praticata da uomini. Tra le pochissime donne operanti e militanti è certamente da ricordare Luciana Natoli le cui opere e gli scritti definiscono, in quel periodo, un carattere identitario al territorio siciliano. Per comprendere compiutamente la …
In-process tool-failure detection by means of AR models
1997
The present paper proposes a cutting tool breaking and chipping detection system for continuous and interrupted cutting, based on the analysis of the cutting force componentsFx andFy. A multifactorial experimental design has been carried out, to take account of the variability of the force signal. An adaptive signal processing algorithm is proposed, which detects catastrophic failure when at least one component deviates outside an estimated oscillation band for a time duration longer than a prefixed interval. The algorithm has been implemented on a four-microprocessor transputer board. Several tests confirmed the validity of the approach for detecting breaking and chipping phenomena in a fe…
A tool for a first analysis of architectural façades
1997
Abstract This work presents a tool for analysing the figurative structure of architectural facades. The procedure begins by singling out the elementary shapes which make up the facade image; it detects and identifies them as “area objects”, even if present in combination in virtual or mental form and groups them into classes of equal objects. A second step is the analysis of the inner structure of the classes: equidistant, arithmetical and geometrical sequences, or alternate distances are distinguished. The procedure ends by singling out the symmetries which structure the facade image and displaying them, pointing out their implied hierarchy through a thickness differentiation.
Theoretical and Experimental Model for the Analysis of a Cardan Cross
2015
The work presents the aproach of initial moddeling and calculus in order to prepare an finite element investigation of the cardan transmission joint. For this, it is necessary to develop a flexible informational system that would connect the constructive design of cardan transmissions to the technological design within a unitary structure. Due to the typodimensional diversity of cardan transmissions, the design and manufacturing of the various components for a certain application domain (medical aparature, dental and agricultural machines, lifting and transportation machines etc.) has been typified. In order to study the problems that occur in the practice of using cardan transmissions, the…
Computer Simulation Paradigm Regarding the Structure and Mechanical Characteristics of Human Long Bones
2013
Given the complex form of the long bones, a quality method of geometrical modeling which provides a good result is that of the 3D modeling by reconstruction, using the principles of reverse engineering. One of the important problems that shall be taken into consideration while modeling is the one concerning the real structure of the bones. This aspect presents a lot of importance because from the point of view of the mechanical behavior, the bones are neither homogenate structures. In this paper a study of the long bones structures is undergone, and in relation to the modelated element (the human tibia) it is divided in areas (called constructive-anatomical entities) of different mechanical…
A Proposal to Model Ancient Silk Weaving Techniques and Extracting Information from Digital Imagery - Ongoing Results of the SILKNOW Project
2019
Three dimensional (3D) virtual representations of the internal structure of textiles are of interest for a variety of purposes related to fashion, industry, education or other areas. The modeling of ancient weaving techniques is relevant to understand and preserve our heritage, both tangible and intangible. However, ancient techniques cannot be reproduced with standard approaches, which usually are aligned with the characteristics of modern, mechanical looms. The aim of this paper is to propose a mathematical modelling of ancient weaving techniques by means of matrices in order to be easily mapped to a virtual 3D representation. The work focuses on ancient silk textiles, ranging from the 15…
Attraversare
2016
L'articolo propone alcune riflessioni sul concetto di "attraversamento dell'architettura" tramite l'implicazione delle arti visuali e del teatro danza. In particolare, è stata approfondito tale concetto realizzando un "attraversamento" della concatenazione spaziale di Palazzo Riso, Museo d'Arte Contemporanea di Palermo, filtrando lo spazio con la scansione temporale della danza. La performance di teatro danza prende avvio in un precedente momento architettonico, cioè nella Piazza Bologni, che costituisce una delle due estremità del percorso teatrale-spaziale. La piazza costituisce il momento della riflessione, dall'esterno verso l’interno, di una serie di avvenimenti attraverso i quali pren…
