Il mattone cuneiforme maiolicato. Procedure algoritmico-parametriche digitali come strumento di indagine e progettazione: dall'architettura storica a…
2020
The study focuses on the cuneiform in majolica brick that has been widespread in Sicily since the 16th century for the construction of spires and domes. A unifying element that has constituted a particular identity contribution to the island’s brick tradition; an original solution able to combine aesthetics with structural and durability. On the basis of more than a hundred examined cases, the different geometrical-formal peculiarities detected in relation to the characteristics of the shell are described. Some analyses and checks of the traditional geometrical composition patterns of the wall facade are reported. Through the definition of digital tools of algorithmic-parametric design, new…
Deceptive design e disinformazione. Il ruolo delle tecnologie persuasive nella diffusione delle fake news.
2022
Dal 2016, la letteratura scientifica ha registrato una drastica crescita dell’interesse per il tema delle fake news e ha dimostrato la responsabilità dei progettisti nel supportare fenomeni di polarizzazione. L’applicazione malevola di principi di psicologia cognitiva alla progettazione delle interfacce digitali, detta deceptive design, persegue la manipolazione dell’utente e gioca un ruolo chiave nella diffusione delle fake news: questo contributo offre un insieme di strumenti utili all’identificazione di notizie false, testati in fase di popolazione del database di news per l’addestramento di un algoritmo di verifica nell’ambito del progetto Fake News.
The tree of life in the southern porch of the cathedral of Palermo: survey and geometric analysis
2016
This study focuses one of the most puzzling works of art made in Palermo at the end of the medieval age: the tree of life, a rich geometrical decoration with animal and human figures in the southern porch of the Cathedral of Palermo. Topographic and SfM photogrammetric methods produced a detailed orthophoto of the porch. Images collected during restoration have been rectified and superimposed to the orthophoto. The geometrical analysis of the decorative patterns reveals a complex design and meaningful links between the decoration and the general architectural layout of the porch.
La rappresentazione dell'architettura in alcuni rivestimenti musivi di epoca medievale in Sicilia
2019
Nei mosaici che decorano le chiese costruite in Sicilia nel XII dai re normanni compaiono rappresentazioni di edifici. Tali rappresentazioni, come frequentemente accade in epoca pre-rinascimentale, condensano, per accostamento, diverse ‘viste’ dello stesso edificio. La presenza negli edifici normanni di pavimenti e manufatti lignei decorati secondo pattern geometrici, ha suggerito la ricerca di analoghi tracciati nei rivestimenti musivi. L’analisi grafica propone la presenza di quadrati e ottagoni stellati in un mosaico della Cappella palatina di Palermo che raffigura un padiglione coperto da una cupola. Many buildings are depicted in the mosaic panels that enrich the churches built in Sici…
Hardware and Software Platforms for Distributed Computing on Resource Constrained Devices
2014
The basic idea of distributed computing is that it is possible to solve a large problem by using the resources of various computing devices connected in a network. Each device interacts with each other in order to process a part of a problem, contributing to the achievement of a global solution. Wireless sensor networks (WSNs) are an example of distributed computing on low resources devices. WSNs encountered a considerable success in many application areas. Due to the constraints related to the small sensor nodes capabilities, distributed computing in WSNs allows to perform complex tasks in a collaborative way, reducing power consumption and increasing battery life. Many hardware platforms …
Building agents with agents and patterns
2006
The use of design patterns proved successful in lowering the development time and number of errors when producing software with the object-oriented paradigm. Now the need for a reuse technique is occurring for the emergent agent paradigm, for which a great effort is currently spending in methodology definitions. In this work we present our experiences in the identification, description, production and use of agents patterns. A repository of patterns was enriched during these years so to request a classification criteria and a documentation template useful to help user during the selection
The eXtensible Dynamic Presentation Manager for content adaptation
2008
Human Computer Interaction studies deals with systems and tools that are able to improve user experience during interaction with computer. For this purpose, modern web application are expected to supply multimodal and multi-channel access, adaptivity and transcoding features. We will present in this work the eXtensible Dynamic Presentation Manager (XDPM) which is a set of innovative tools that support the eXtensible Presentation Language (XPL) in the adaptation of contents to different working contexts. The adaptation is performed according to the delivery context information which have been formalized by means of a profiler system. A profile holds information about the specific access devi…
Entropy-based Localization of Textured Regions
2011
Appearance description is a relevant field in computer vision that enables object recognition in domains as re-identification, retrieval and classification. Important cues to describe appearance are colors and textures. However, in real cases, texture detection is challenging due to occlusions and to deformations of the clothing while person's pose changes. Moreover, in some cases, the processed images have a low resolution and methods at the state of the art for texture analysis are not appropriate. In this paper, we deal with the problem of localizing real textures for clothing description purposes, such as stripes and/or complex patterns. Our method uses the entropy of primitive distribu…
Mathematical Patterns and Cognitive Architectures
2014
Mathematical patterns are an important subclass of the class of patterns. The main task of this paper is examining a particular proposal concerning the nature of mathematical patterns and some elements of the cognitive architecture an agent should have to recognize them.
THE INFLUENCE OF TEXTURE SYMMETRY IN MARKER POINTING: EXPERIMENTING WITH HUMANS AND ALGORITHMS
2011
Symmetry plays a fundamental role in aiding the visual system, to organize its environmental stimuli and to detect visual patterns of natural and artificial objects. Various kinds of symmetry exist, and we will discuss how internal symmetry due to textures influences the choice of direction in visual tasks. Two experiments are presented: the first, with human subjects, deals with the effect of textures on preferences for a pointing direction. The second emulates the performances obtained in the first through the use of an algorithm based on a physic metaphor. Results from both experiments are shown and comment.
