Re-drawing of vanished space: Casa Giobbe della Bitta by Marcello Piacentini
2020
Ha ancora un senso oggi, nel tempo dominato dall’immagine e dal suo potere, interrogarsi sulle ragioni e sulle potenzialità del Disegno di Architettura? Potremmo sfruttare, invece, questa forza immateriale che pervade la nostra era contro il modus operandi della tabula rasa che interessa il patrimonio del moderno in Italia? Un tentativo di risposta a queste domande potrebbe giungere dallo studio di un’opera non più esistente di Marcello Piacentini, Casa Giobbe della Bitta, del 1925. A partire dal ridisegno critico dell’edificio, si vuol tentare una decodifica dell’architettura svanita, analizzandone forme e matrici geometriche che l’hanno generata; la modellazione tridimensionale digitale, …
Images of the imagined city
2018
The essay investigates one of the projects in the competition for the expansion of the North area of Palermo named ZEN 2 and designed by the architects Pasquale Culotta, Giuseppe Laudicina, Teresa Cannarozzo, Anna Maria Fundarò and Tilde Marra, in 1970. The essay aims at illustrating the spatial, figurative and urban qualities of it. The analysis of the project has been guided by a written text and the graphic support, that is the project report and the attached drawings, in Indian Ink, made by the architects themselves, indeed very often fragmented and difficult to be interpreted. In this regard, the support of digital drawing in two-dimensional and three-dimensional form, based on the cre…
Alphabet as a pretext. Representation and architecture starting from J.D. Steingruber
2020
Johann David Steingruber (1702-87) realizzò nel 1773 l’ “Alfabeto Architettonico” (titolo originale “Architektonisches Alphabeth bestehend aus 30 Rissen”),ovvero un compendio di edifici immaginari le cui piante presentano la forma delle lettere dell’alfabeto. A partire dall’analisi delle tavole, obiettivo del contributo è presentare una riflessione su questi disegni, sia in relazione alle intrinseche caratteristiche storiche ed estetiche, sia in relazione alla personalità dello Steingruber. Johann David Steingruber (1702-87) realized in 1773 the “Architectural Alphabet” (original title “Architektonisches Alphabeth bestehend aus 30 Rissen”), that is a compendium of imaginary buildings with p…
Villa Colli by Giuseppe Pogatschnig Pagano and Gino Levi-Montalcini: some graphic reflections
2019
Villa Colli è una delle testimonianze più vivide della collaborazione professionale di due protagonisti dell’architettura del primo novecento italiano, come Giuseppe Pagano e Gino Levi-Montalcini. Costruita nelle campagne appena fuori Rivara, in Provincia di Torino, alla fine degli anni ’20, presenta caratteri di unicità finora non particolarmente esplorati dalla critica storiografica. Con questa ricerca si tenta di colmare tale vuoto, usando una metodologia che vede l’applicazione degli strumenti classici della Scienza della Rappresentazione, ossia disegno, rilievo, modellazione tridimensionale digitale e analisi grafica, qui adoperati come dispositivi di indagine e decodifica dello spazio…
Virtual tour through the towers of the defensive system in the province of Salerno
2019
The coastal towers of the defensive system in the province of Salerno are architectures developed over time; they are buildings belonging to an extended strategic plan of the coastal territory useful to defend populations and cities from the ancient enemy attacks. Hence, their location comes from careful studies in which the orographic characteristics of the place and the visual connection between a tower and another played a fundamental role.The aim of this work is to focus the attention on the visual communication between the towers, or on the “dialogue” that the different artefacts entertain each other. In order to pursue this objective, a virtual tour that connects the different ancient…
Digital Vitruvius, or an elogy of the equilateral triangle
2012
On interpretation of an architectural project, triangle’s form generally refers both to plans of organic architecture and to fronts of Romanesque and Gothic churches. This wonderful form, that contains God’s eye, is, according to Vitruvius, the geometric generative principle of the Roman Theatre. Everybody knows that De Architectura arrived to us without images; in the past there were innumerable interpretations, from editio princeps (1486). A digital transcriptions, that follows side by side a Vitruvius’ book’s translation, highlights the compositional process that defines that the equilateral triangle is the geometric element that give origin to the composition of theatre.
Una rappresentazione dell'architettura stratificata
2009
<p>La representación de una construcción y su restitución gráfica, es un código que permite conocer todas las informaciones que el edifico puede ofrecer.</p><p>En la época del levantamiento “no selectivo” por el escáner- laser, creemos que existe la posibilidad de considerar la tarea del levantamiento de planos, no solo como la organización de trabajos prácticos, si no como una filosofía metodológica.</p>
A tabu search algorithm for the bipartite drawing problem
1998
Graphs are used to represent reality in several areas of knowledge. This has generated considerable interest in graph drawing algorithms. Arc crossing minimization is a fundamental aesthetic criterion to obtain a readable map of a graph. The problem of minimizing the number of arc crossings in a bipartite graph (BDP) is NP-complete. In this paper we present a Tabu Search (TS) scheme for the BDP. Several algorithms can be obtained with this scheme by implementing different evaluators in the move definitions. In this paper we propose two variants. Computational results are reported on a set of 300 randomly generated test problems. The two algorithms have been compared with the best heuristics…
Variable Neighborhood Search for the Vertex Separation Problem
2012
The vertex separation problem belongs to a family of optimization problems in which the objective is to nd the best separator of vertices or edges in a generic graph. This optimization problem is strongly related to other well-known graph problems; such as the Path-Width, the Node Search Number or the Interval Thickness, among others. All of these optimization problems are NP-hard and have practical applications in VLSI, computer language compiler design or graph drawing. Up to know, they have been generally tackled with exact approaches, presenting polynomial-time algorithms to obtain the optimal solution for speci c types of graphs. However, in spite of their practical applications, these…
IMFLer: A Web Application for Interactive Metabolic Flux Analysis and Visualization.
2021
Increasing genome-wide data in biological sciences and medicine has contributed to the development of a variety of visualization tools. Several automatic, semiautomatic, and manual visualization tools have already been developed. Some even have integrated flux balance analysis (FBA), but in most cases, it depends on separately installed third party software that is proprietary and does not allow customization of its functionality and has many restrictions for easy data distribution and analysis. In this study, we present an interactive metabolic flux analyzer and visualizer (IMFLer)-a static single-page web application that enables the reading and management of metabolic model layout maps, …
