Nueva aplicación potencial de dos técnicas instrumentales para la caracterización de materiales de construcción prehistóricos

En este trabajo se ponen de manifiesto las ventajas de la utilización de la Termogravimetría acoplada a Espectrometría de masas (TG-EM) y de la Espectrometría Infrarroja mediante Reflectancia Total atenuada (ATR-FTIR) frente a las técnicas usadas tradicionalmente de Termogravimetría (TG) y de Espectroscopia Infrarroja por Transformada de Fourier en modo transmisión (FTIR) en el estudio de materiales de construcción prehistóricos de diversos yacimientos de la Provincia de Alicante (España).

Image processing for safety assessment in Civil Engineering

Behaviour analysis of construction safety systems is of fundamental importance to avoid accidental injuries. Traditionally, measurements of dynamic actions in Civil Engineering have been done through accelerometers, but high-speed cameras and image processing techniques can play an important role in this area. Here, we propose using morphological image filtering and Hough transform on high-speed video sequence as tools for dynamic measurements on that field. The presented method is applied to obtain the trajectory and acceleration of a cylindrical ballast falling from a building and trapped by a thread net. Results show that safety recommendations given in construction codes can be potentially dangerous for workers.

A high-resolution binocular video-oculography system: assessment of pupillary light reflex and detection of an early incomplete blink and an upward eye movement

Background: The pupillary light reflex characterizes the direct and consensual response of the eye to the perceived brightness of a stimulus. It has been used as indicator of both neurological and optic nerve pathologies. As with other eye reflexes, this reflex constitutes an almost instantaneous movement and is linked to activation of the same midbrain area. The latency of the pupillary light reflex is around 200 ms, although the literature also indicates that the fastest eye reflexes last 20 ms. Therefore, a system with sufficiently high spatial and temporal resolutions is required for accurate assessment. In this study, we analyzed the pupillary light reflex to determine whether any small discrepancy exists between the direct and consensual responses, and to ascertain whether any other eye reflex occurs before the pupillary light reflex. Methods: We constructed a binocular video-oculography system two high-speed cameras that simultaneously focused on both eyes. This was then employed to assess the direct and consensual responses of each eye using our own algorithm based on Circular Hough Transform to detect and track the pupil. Time parameters describing the pupillary light reflex were obtained from the radius time-variation. Eight healthy subjects (4 women, 4 men, aged 24–45) participated in this experiment. Results: Our system, which has a resolution of 15 microns and 4 ms, obtained time parameters describing the pupillary light reflex that were similar to those reported in previous studies, with no significant differences between direct and consensual reflexes. Moreover, it revealed an incomplete reflex blink and an upward eye movement at around 100 ms that may correspond to Bell’s phenomenon. Conclusions: Direct and consensual pupillary responses do not any significant temporal differences. The system and method described here could prove useful for further assessment of pupillary and blink reflexes. The resolution obtained revealed the existence reported here of an early incomplete blink and an upward eye movement.

Puesta en valor de la arquitectura moderna residencial post-terremoto de 1944. San Juan – Argentina

La ciudad y su arquitectura testimonian las culturas que modelan y remodelan sus formas y espacios en el tiempo. Toda comunidad tiene derecho a un ambiente urbano apto para el desarrollo humano sustentable. Desarrollo sustentable, es aquel que asegura la satisfacción de las necesidades del presente, sin comprometer los recursos con que generaciones futuras puedan satisfacer las propias (Naciones Unidas, 1987). Significa el uso racional y responsable de toda clase de recursos, especialmente los no renovables, como el patrimonio arquitectónico. La ciudad de San Juan fue reconstruida bajo influencias de los postulados del Movimiento Moderno tras el terremoto de 1944 que destruyó casi la totalidad de sus edificios patrimoniales. La arquitectura moderna es considerada internacionalmente un patrimonio a legar a las generaciones futuras. En San Juan, las obras residenciales modernas corren el riesgo de ser transformadas o demolidas ante un posible reemplazo por nuevas obras más redituables, por la dinámica del desarrollo urbano y la ausencia de protección que preserve este patrimonio. Es objetivo de este trabajo promover el reconocimiento, valoración y protección, de obras patrimoniales residenciales, exponentes de la modernidad arquitectónica local.
