Un testigo del arte barroco "novator" valenciano de "La Vall de Gallinera": la iglesia parroquial de San Miguel de Benissivà
2002
El estudio nos presenta una muestra de recuperación de artesanías tradicionales en el medio rural como proyecto de enseñanza-aprendizaje de la Universitat de València y su Área de Conservació del Patrimoni Cultural, desde unos análisis histórico-material, histórico-artístico y técnico, en torno a la intervención llevada a cabo en la iglesia de San Miguel de Benissivà de Alicante. Buscando su valoración dentro del conjunto patrimonial al cual pertenece, se acomete una investigación sobre dicho templo y sus transformaciones, sus orígenes, evolución y creadores (entendidos dentro de la etapa artística valenciana de esplendor barroco y clasicismo matemático en la que se encuentran inmiscuidos),…

Transports et offre scolaire : arbitrages à revoir...
1998
The paper examines the tradeoffs that can exist in rural settings between the supply of classes and that of pupils transportations. A conclusion is that in the current circumstances, it could preferable to extend the number of villages in which the school is organised (via multigrade teaching) while reducing the number of pupils using busses. Since the operation cost of schools are born mostly by the State while the financing of bussing is born by the local communities, the paper opens a discussion on the balance of the financing between the two bodies.
A comparison of two different formulations for Arc Routing Problems on Mixed graphs
2006
[EN] Arc routing problems on mixed graphs have been modelled in the literature either using just one variable per edge or associating to each edge two variables, each one representing its traversal in the corresponding direction. In this paper, and using the mixed general routing problem as an example, we compare theoretical and computationally both formulations as well as the lower bounds obtained from them using Linear Programming based methods. Extensive computational experiments, including some big and newly generated random instances, are presented.
New Heuristic Algorithms for the Windy Rural Postman Problem
2005
[EN] In this paper we deal with the windy rural postman problem. This problem generalizes several important arc routing problems and has interesting real-life applications. Here, we present several heuristics whose study has lead to the design of a scatter search algorithm for the windy rural postman problem. Extensive computational experiments over different sets of instances, with sizes up to 988 nodes and 3952 edges, are also presented. (c) 2004 Elsevier Ltd. All rights reserved.
A branch-and-cut algorithm for the Profitable Windy Rural Postman Problem
2016
[EN] In this paper we study the profitable windy rural postman problem. This is an arc routing problem with profits defined on a windy graph in which there is a profit associated with some of the edges of the graph, consisting of finding a route maximizing the difference between the total profit collected and the total cost. This problem generalizes the rural postman problem and other well-known arc routing problems and has real-life applications, mainly in snow removal operations. We propose here a formulation for the problem and study its associated polyhedron. Several families of facet-inducing inequalities are described and used in the design of a branch-and-cut procedure. The algorithm…
Un nuovo insediamento rurale nel territorio dei Monti Sicani tra epoca bizantina e normanna: dati preliminari sul sito di lunga durata di Contrada Ca…
2018
Negli ultimi anni (2015-2017) sono state avviate delle ricerche archeologiche sulle dinamiche diacroniche dei paesaggi di una porzione di territorio localizzata a sud del comune di Corleone corrispondente alle contrade Castro e Giardinello delimitate a nord dal massiccio promontorio di Pizzo Castro o Rocche di Mezzogiorno e ad est dalle pendici del Monte Barraù. Il progetto Harvesting Memories ha previsto diverse fasi di studio relative alle traiettorie ecologiche e alle trasformazioni del paesaggio (Università di Palermo) e indagini archeologiche (Soprintendenza BB. CC. AA. di Palermo). In questo contributo si presentano i risultati preliminari di una prima campagna di scavo (marzo-maggio …
Segunda campaña de excavación en el asentamiento ibérico final de la Casa de la Cabeza (Requena, València)

Second report about the excavations in Casa de la Cabeza, an iberian rural settlement (IInd century BC).
El registro material del colmenar ibérico de la Fonteta Ràquia (Riba-Roja, València)
2016
La excavación arqueológica en 2008 del yacimiento de la Fonteta Ràquia (Riba-Roja del Túria, València) permitió documentar un pequeño asentamiento rural de la Edetania, territorio de la antigua ciudad ibérica de Edeta / Tossal de Sant Miquel (Llíria, València). El núcleo estuvo ocupado entre finales del s. V a.C. y finales del III / comienzos del II a.C. Destaca, por encima de todo, por una gran especialización en apicultura, tal y como demuestra el hallazgo de miles de fragmentos de aproximadamente 200 colmenas cerámicas, superando con creces los registros precedentes de este tipo de actividad en Iberia y el Mediterráneo en general. The archaeological excavation of the site in Fonteta Ràqu…
