The Mathematical Table of the Palazzina Cinese in Palermo. Animation and Virtual Reality Techniques for an Edutainment Project
2023
The Palazzina Cinese of Palermo was built on a project by Venanzio Marvuglia in 1799 on behalf of Ferdinand IV of Borbone, when the royal family, fleeing from Naples following the establishment of the Parthenopean Republic, moved to Sicily. The building, known as “Chinese” due to its style, is full of particular architectural and decorative solutions. An element of particular interest is theMathematical Table, designed to avoid any contact between the living room and the kitchen below, isolating it from smells and servants. Thanks to a complex system of winches and pulleys, in fact, the dishes could be served by letting the central portion of the table and small circular areas fall into the…
Innovative techniques for survey and communication of cultural heritage
2008
This paper deals with the survey and communications of Cultural Heritage through the development of innovative methodologies. The case of study is the polychrome wooden ceiling in the “Magna” Hall of “Palazzo Steri”. The “Steri”, built in the XIVth century by the noble family Chiaromonte, is at the present the headquarter of the Rector’s Office of Palermo University. A 3D model of the wooden ceiling has initially been carried out with laser-scanning and digital photogrammetric techniques; successively a multimodal interactive guide has been realized. The guide is integrated to the 3D model, so that visitors can navigate the virtual representation of the ancient wood ceiling and achieve, int…
E-wave and heart rate responses during anticipation of nonmotor events.
1994
This study concentrated on three main questions: 1) can anticipatory late negative shift (expectancy wave, E-wave) be elicited in nonmotor S1-S2 paradigm, 2) is it sensitive to variation of emotional aspects of the task and 3) is there a connection between heart rate (HR) responses and E-wave. S1 was a letter row that was replaced tachistoscopically by another letter row (S2). The task of the subjects (n = 12) was to detect if the critical aspects of S2 were similar to S1. After their delayed response they received feedback of their performance. The emotional aspects of the task were varied by presenting aversive noise bursts at the end of the feedback period either always, contingently to …
La heterodoxia en la poesía visual española del siglo XXI
2014
Resumen: Toda vanguardia esconde un malestar y una rebeldia contra la realidad que aflige al individuo y que se vuelve objeto de critica en las obras. En este sentido, tras aclarar a que nos referimos cuando hablamos de poesia visual, analizaremos algunas obras que han aparecido por primera vez en 2014, interpretandolas como reaccion contra la perdida de valores de la sociedad postmoderna. La finalidad sera demostrar que la poesia visual espanola del siglo XXI no ha renunciado a su heterodoxia, puesto que elige justamente este universo donde todo es rapido, fluido, superficial, complejo e inasible para seguir denunciando desde su interior la incomunicacion y la alienacion a la que nos han l…
A cultural heritage experience for visually impaired people
2020
Abstract In recent years, we have assisted to an impressive advance of computer vision algorithms, based on image processing and artificial intelligence. Among the many applications of computer vision, in this paper we investigate on the potential impact for enhancing the cultural and physical accessibility of cultural heritage sites. By using a common smartphone as a mediation instrument with the environment, we demonstrate how convolutional networks can be trained for recognizing monuments in the surroundings of the users, thus enabling the possibility of accessing contents associated to the monument itself, or new forms of fruition for visually impaired people. Moreover, computer vision …
Changes in physiological astigmatism of human eye during accommodation in emmetropes (Conference Presentation)
2017
Introduction: Most young emmetrope eyes are far from ideal and have some degree of minor spherocylindrical error including also physiological astigmatism. Because of the changes in the shape of optical interfaces, pupil size, eyelid pressure, tear film, body posture, binocularity and accommodation astigmatism is considered as constantly dynamic phenomenon (Cheng et al, 2004). The purpose of this study was to evaluate and quantify changes in physiological astigmatism during accommodation. Method: Twenty young emmetropes with mean age 24 ± 4 years were selected for the study. Refraction and accommodative response were measured monocularly for dominant eye with an open-field infrared autorefract…
Mafalda and museum educators. Strategies for teaching creation from Childhood Visual Culture
2013
Esta investigación aborda desde la cultura visual infantil un problema educativo -como el del diseño creativo de actividades didácticas de materia artística- mediante intersecciones e interacciones con aspectos de género, crítica social y cultural. Desde el marco conceptual se expone el interés y vigencia de Mafalda como personaje de la cultura visual: por su calado internacional, por haberse empleado con fines pedagógicos con anterioridad, por ser precursora de la crítica al sistema educativo, por ser conocido por todos los integrantes del entramado educativo formal e informal, y por tratar transversalmente cuestiones de género. Desde la pedagogía generativa se intenta alterar la práctica …
Efficacy and safety study of an eyelid gel after repeated nocturnal application in healthy contact lens users and non-users
2020
Purpose: To evaluate skin biocompatibility of a nighttime hydrating eyelid gel and possible ocular surface effects in contact lens users (CLU) and non-contact lens users (NCLU). The formulation is registered as a medical device as Tridocosahexaenoine-AOX® (TDHA-AOX) (a concentrated DHA triglyceride), containing also hyaluronic acid (HA). Methods: A prospective, randomized, masked clinical trial was performed with 62 participants of both sexes, aged 20–70 years, split into: (1) CLU (n = 30) and (2) NCLU (n = 32). All participants were instructed to apply a single dose of the moisturizing gel (containing TDHA-AOX and HA) nightly to the upper and inner eyelids of their right eye (RE) only, and…
Dynamic Perception of Plastic Movements: Biomechanics and Digital Artifacts
2017
The article offers some reflections on the body-space relationship through images, graphic translations and visual studies that converge into a contemporary digital illuminated avant-garde of the fourth virtual dimension. Starting from the study of the Soviet coreutics of the 1920s and the biomechanics of multimedia performances, it moves on the cinesthetic suggestions and to the dance theorization integrated with the musical score. Finally, some contemporary forms of digital image production are taken into account by addressing a number of issues regarding the exploration of the object-image and its experiential re-elaboration through the production of new graphic knowledge.
