Mixed Stone-timber Masonry in Traditional Construction: Structural, Architectural and Anti-seismic Features across Europe
2018
This paper investigates the stone masonry with timber reinforcement through the European traditional and historical architecture. It is a remarkable practice consisting of combining different materials to build up a masonry. This technology shows a wide variety of typological, formal, and technological types of buildings across Europe as it is strongly influenced by the nature and availability of local materials, the cultural aspects of the various communities, and the soils geological nature. As a consequence, the same constructive typology is based on different premises and leads to many interesting results. In this paper the various uses of such a mixed stone-timber masonry are shown in …
BEM analysis of a piezoelectric structural health monitoring system for delamination detection
2013
In the present work a piezoelectric based structural health monitoring (SHM) system is analyzed with the aim of assessing the ability of the piezoelectric patch to detect both edge and embedded delaminations proper of flange-skin composite laminated structures. he boundary element model is developed for piezoelectric solids and is implemented by taking advantage of the multidomain technique to model laminated and cracked configurations. A non-linear spring model interface is then implemented in conjunction with an iterative procedure allowing for the simulation of the finite stiffness of the bonding layers as well as of the non-penetration condition of the delamination surfaces. he dynamic …
On the use of the EMI for the health monitoring of bonded elements
2014
The low weight, robustness and fatigue resistance of adhesive joints make them suitable for structural joints. A fully developed nondestructive evaluation technique however is needed to monitor and assess the quality of bonded joints. In the present paper the application of the electromechanical impedance (EMI) technique is proposed. In the EMI method a piezoelectric transducer (PZT) is attached to the structure of interest. The high sensitivity and low power consumption make the EMI method feasible for real time structural health monitoring. In this study we investigated the sensitivity of the electromechanical response of a PZT to the curing and the quality of the adhesive used for bonded…
Multi-objective Optimization for Computation Offloading in Fog Computing
2018
Fog computing system is an emergent architecture for providing computing, storage, control, and networking capabilities for realizing Internet of Things. In the fog computing system, the mobile devices (MDs) can offload its data or computational expensive tasks to the fog node within its proximity, instead of distant cloud. Although offloading can reduce energy consumption at the MDs, it may also incur a larger execution delay including transmission time between the MDs and the fog/cloud servers, and waiting and execution time at the servers. Therefore, how to balance the energy consumption and delay performance is of research importance. Moreover, based on the energy consumption and delay,…
Socially-aware Dynamic Computation Offloading Scheme for Fog Computing System with Energy Harvesting Devices
2018
Fog computing is considered as a promising technology to meet the ever-increasing computation requests from a wide variety of mobile applications. By offloading the computation-intensive requests to the fog node or the central cloud, the performance of the applications, such as energy consumption and delay, are able to be significantly enhanced. Meanwhile, utilizing the recent advances of social network and energy harvesting (EH) techniques, the system performance could be further improved. In this paper, we take the social relationships of the EH mobile devices (MDs) into the design of computational offloading scheme in fog computing. With the objective to minimize the social group executi…
Emma Zaragoza: mujer del artista, compañera de viaje, musa y coleccionista
2021
La mayoría de las obras realizadas por Joaquín Agrasot escapan a la narración de la consideración social del artista o de su éxito en los circuitos expositivos y comerciales. Gran parte de su obra se realizó en un contexto íntimo y familiar, en el que la obra se convertía en recurso de la memoria o el obsequio al ser querido. En este escenario debemos situar algunos de sus autorretratos realizados con el fin de ser destinados al recuerdo familiar o como parte de la celebración familiar, especialmente asociada a la llegada de un nuevo miembro a la familia de Agrasot. Pero será a su mujer Emma a quien retratará en diversas ocasiones.
La memoria vivida: el arte de Joaquín Agrasot como expresión de la vida íntima
2021
Muchas de las obras de Joaquín Agrasot nos hablan de una dimensión personal, más íntima, a través de la que nos permite eludir la supresión de una memoria existencial, en la que el relato se establece a través de la mirada del artista y de la representación. Estas obras, quizá de las menos conocidas, de la producción del pintor oriolano son también un instrumento de análisis social.
Joaquín Agrasot. Un pintor internacional
2021
En 1902, la Encyclopaedia Britannica resumía de forma rotunda la situación de la pintura española de la segunda mitad del siglo XIX. Consideraba que la pintura moderna en España comenzaba con Mariano Fortuny (1838-1874), quien habría de dejar su marca en las siguientes generaciones de pintores. Y destacaba solamente a un artista durante los años de 1870, Joaquín Agrasot y Juan (1836-1919), quien pintó con gran sinceridad imágenes de la vida española cotidiana. Y, concluía que, ya para finales del siglo, dos jóvenes artistas aparecieron con energía: Joaquín Sorolla (1863-1923) e Ignacio Zuloaga (1870-1945). Por tanto, el pintor valenciano Joaquín Agrasot había adquirido una consideración a p…
Introducció a la vida i obra de Joaquín Agrasot
2021
Joaquín Agrasot fallecía en Valencia el 8 de enero de 1919 a los 82 años de edad. Su trayectoria artística tuvo una faceta cosmopolita a menudo ensombrecida por su estrecha amistad con Mariano Fortuny, con quien visitó distintos lugares e incluso veranearon, junto a sus esposas, en la Villa Arata de Portici. En su etapa italiana formó parte de la colonia española en Roma junto a Fortuny, Antonio Casanova Estorach, José Tapiró y Ramón Tusquets, acogidos en el círculo del príncipe Odescalchi, aristócrata romano y teórico artístico. La muerte prematura de Fortuny, en 1874, le mueve a regresar a tierras valencianas donde llegó a convertirse en todo un referente para la siguiente generación de p…
VELENI ED ALCHIMIE NEI MATERIALI DELL’EDILIZIA PRE INDUSTRIALE
2019
Since at least two decades, a renewed sensitivity to biocompatibility and the consequent diffusion of eco-certified building products have led to the attention of designers and operators on the issue of the healthness of construction materials. Although the application of strict protocols guarantees for new constructions very high levels of healthiness for both construction workers and users who come into direct contact with building materials and components, the issue for the characterization of potentially hazardous materials arises in many case for historical buildings. In addition to the well-known asbestos problem, there are new worrying signs deriving from the ascertainment in the inc…
