Towards the definition of a sustainable Smart Model for the suburbs redevelopment
2020
Starting from the analysis of the problems that characterize the Italian suburbs, the application of a Smart Methodology to a real peripheral area is presented. In literature, several studies underline the urgent request of the city's periphery, enhancing local and national projects to increase the quality of life in the suburbs. In this framework, authors propose a multifunctional centre development, characterized by modern technologies (both structural and plant) to implement energy efficiency and social aggregation, in line with the citizen's needs. Once the simulation model of alternative solutions, such as construction type, energy system and social services, was elaborated in Matlab/S…
“Sources of Research” for the Virtual Reconstruction of Ancient Monuments: The Case of Architectural Models
2023
The use of architectural scale models, also known by the French word maquette or the Italian names plastico or modello, is an ancient practice, which prob-ably began when architecture emerged from its purely practical and utilitarian phase to become a formal category of knowledge with specifically sought-after and deliber-ately selected characteristics, linked to the increased dimensions and the enrichment of forms [1]. The model constitutes a representation, generally on a smaller scale and made of different materials but similar in effect, of a work to be created. Models are made of various materials, in accordance with the tastes of Scholars and with need, such as wood, wax, terracotta, …
Architectural Perspectives in the Cathedral of Palermo: Image-Based Modelling for Cultural Heritage Understanding and Enhancement
2015
Palermo off ers a repertoire of both artistic and architectural solid perspective of great beauty and in large quantity. This paper addresses the problem of the 3D survey of these works and their related study through the use of image-based modelling (IBM) techniques. We propose, as case studies, the use of IBM techniques inside the Cathedral of Palermo. Indeed, the church houses a huge and rich sculptural repertoire, dating back to 16th century, which constitutes a valid field of IBM techniques application. The aim of this study is to demonstrate the e ffectiveness and potentiality of these techniques for geometric analysis of sculptured works. Indeed, usually the survey of these artworks …
Arqueometría y georreferenciación con gvSIG en un yacimiento al aire libre. Campaña Mas d'Is 2015
2016
La Arqueología ha sido pionera entre las Humanidades en la utilización de los avances tecnológicos para acercarse al conocimiento histórico, lo que ha facilitado y mejorado el trabajo posterior de los datos registrados. Con programas como gvSIG, se pueden realizar estos estudios y georreferenciar unidades estratigráficas (UUEE), configurar la forma de estructuras o ubicar en el espacio las piezas arqueológicas encontradas, dotando de un significado más completo al trabajo de campo. En esta comunicación, aportamos nuestra experiencia para el tratamiento de datos del yacimiento neolítico de Mas d'Is (Penàguila, Alicante). La campaña de 2015 se abordó desde su inicio con el ánimo de informatiz…
Campañas de excavación recientes en el yacimiento Mas d'Is (Penàguila, Alacant)
2014
Las diferentes actuaciones arqueológicas realizadas en el yacimiento del Mas d'Is (Penàguila, Alacant) han mostrado depósitos que datan del Holoceno Antiguo - Medio. El trabajo de campo en este emplazamiento neolítico es uno de los proyectos que el Departament de Prehistòria i Arqueologia de la Universitat de València lleva a cabo en esta región. Las campañas previas han puesto de manifiesto la existencia de grandes estructuras negativas en el extremo norte del yacimiento. Presentamos aquí los resultados obtenidos en los ultimos años. Archaeological works at the site of Mas d'Is (Penàguila, Alacant) have revealed important deposits dating back to the Early Holocene. The more recent field se…
Isótopos en la Prehistoria y Arqueología Valencianas
2017
Desde su primera aplicación en Arqueología y Prehistoria en la década de 1970, los análisis isotópicos se han desarrollado rápidamente durante las últimas décadas y se han convertido en una herramienta crucial en la investigación arqueológica. Esto ha ocurrido gracias a su gran versatilidad, los avances y refinamientos en la metodología y, en especial, por la reducción significativa de los costes de análisis, de la cantidad de material requerido, del grado de invasión en el muestreo del material y de los tiempos de retorno de resultados. Todos estos factores han contribuido sin duda a que actualmente las caracterizaciones isotópicas de los registros arqueológicos sean una aproximación rutin…
Sequence and context for the Cocina cave neolithic pottery: An approach from social networks analysis
2023
Cocina cave has been considered one of the main sites when explaining the transition from Mesolithic to Neolithic in the Iberian Mediterranean façade. But the current review of its stratigraphy has evidenced important post-depositional disturbances affecting those layers where Neolithic pottery is present. These taphonomic problems question the usefulness of this record in any detailed approach to a potential process of acculturation of the local Mesolithic groups. Despite this negative preservation, and using decorative traits as a proxy, we have isolated two ceramic contexts with inner coherence. Over these contexts, we have developed a Bayesian approach to compare them with other well-da…
Optimal Guard Placement Problem Under L-Visibility
2006
Two points a and b in the presence of polygonal obstacles are L-visible if the length of the shortest path avoiding obstacles is no more than L. For a given convex polygon Q, Gewali et al [4]. addressed the guard placement problem on the exterior boundary that will cover the maximum area exterior to the polygon under L-visibility. They proposed a linear time algorithm for some given value of L. When the length L is greater than half of the perimeter, they declared that problem as open. Here we address that open problem and present an algorithm whose time complexity is linear in number of vertices of the polygon.
Intraocular Telescopic System Design: Optical and Visual Simulation in a Human Eye Model
2016
Purpose. To design an intraocular telescopic system (ITS) for magnifying retinal image and to simulate its optical and visual performance after implantation in a human eye model. Methods. Design and simulation were carried out with a ray-tracing and optical design software. Two different ITS were designed, and their visual performance was simulated using the Liou-Brennan eye model. The difference between the ITS was their lenses’ placement in the eye model and their powers. Ray tracing in both centered and decentered situations was carried out for both ITS while visual Strehl ratio (VSOTF) was computed using custom-made MATLAB code. Results. The results show that between 0.4 and 0.8 mm of d…
Fuzzy C-Means Segmentation on Brain MR Slices Corrupted by RF-Inhomogeneity
2007
Brain MR Images corrupted by RF-Inhomogeneity exhibit brightness variations in such a way that a standard Fuzzy C-Means (fcm) segmentation algorithm fails. As a consequence, modified versions of the algorithm can be found in literature, which take into account the artifact. In this work we show that the application of a suitable pre-processing algorithm, already presented by the authors, followed by a standard fcm segmentation achieves good results also. The experimental results ones are compared with those obtained using SPM5, which can be considered the state of the art algorithm oriented to brain segmentation and bias removal.
