Noticias de ataques y destrucciones en Orihuela durante el período andalusí (ss. VIII-XIII)

Tras resumirse "Los elementos esenciales de la trama urbana de Orihuela", se estudian los principales hechos históricos durante el período islámico de la ciudad de Orihuela "s. VIII-XIII) en que hay noticia de ataques militares a la ciudad y destrucciones : El ataque de los normandos a Orihuela en 245 H ./859 e.C.; Aceifa del califa ‘Abd al-Raḥmān III al-Nāṣir contra Orihuela y sus rebeldes; La "fitnat al-barbar" o guerra civil que acabó con el califato andalusí; El terremoto posterior a 440 H/1048-9 e.C. que asoló toda la vega del río Segura y finalmente la conquista cristiana de Orihuela. Como conclusiones para el estudio del urbanismo musulmán de Orihuela se demuestra que solo hubo destrucciones en el trazado urbano de importancia como resultado del mencionado terremoto que asoló y destruyó las ciudades de Murcia, Orihuela y toda la Vega Baja del río Segura.

Control of Redundant Joint Structures Using Image Information During the Tracking of Non-Smooth Trajectories

Visual information is increasingly being used in a great number of applications in order to perform the guidance of joint structures. This paper proposes an image-based controller which allows the joint structure guidance when its number of degrees of freedom is greater than the required for the developed task. In this case, the controller solves the redundancy combining two different tasks: the primary task allows the correct guidance using image information, and the secondary task determines the most adequate joint structure posture solving the possible joint redundancy regarding the performed task in the image space. The method proposed to guide the joint structure also employs a smoothing Kalman filter not only to determine the moment when abrupt changes occur in the tracked trajectory, but also to estimate and compensate these changes using the proposed filter. Furthermore, a direct visual control approach is proposed which integrates the visual information provided by this smoothing Kalman filter. This last aspect permits the correct tracking when noisy measurements are obtained. All the contributions are integrated in an application which requires the tracking of the faces of Asperger children.

Rehabilitating, repairing and restoring against demolishing, tearing down and destroying: the recovery of the military fort for the Santa Pola town museum

This communication develops the process of interventions of the Renaissance fortress of a new plant built in 1554–57 in Santa Pola. It is one of the earliest examples built with reference to military architecture theoretical treaties (XV–XVI) and best preserved. The study runs its own story from its initial military use, through the use of civil equipment until the final cultural and Museum Center. First, the project of Italian origin is examined and its use as barracks for troops for a duration of three centuries (1557–1850), pointing out the architectural constants of war machinery in a defense position and its origin as a rainwater collector and cistern: a perfect square with two bastions in which a plan of the uprising is preserved (1778). Secondly, we study the changes in the mentioned architecture throughout a century and a half (1850–1990) after its change of ownership (from the state to the municipality), and as a result of the new use as a city hall and public endowment: a market and health and leisure centre, which meant the demolition of defensive elements and the opening up to the outside of the inner parade ground. And thirdly, the new transfer of the municipal offices brings in the beginning of a project of transformations (1990–2015) that retrieves the demolished elements at the same time as it assigns the entire fort for a cultural centre: exhibition, research and history museum, promoting the identity between the citizens and the building which stands in the foundations of their city. The conclusions take us through an interesting route that goes from the approach of defensive tactics, its use as administrative headquarters to the current cultural policy of preservation. In addition, all the known plans of the fort are recovered (of military, civil and cultural use), some unpublished, as well as the project of the North wing that has guided the last operation and which has been set as a pattern of reference.
