ICT in higher education: an experience with e-books

The present paper seeks to explain the diverse advantages of virtual books and also the main barriers that make it difficult their implementation in the classroom. A brief review of the literature on ICT, e-learning, distance education and e-books will be complemented with a case study about the preparation, development and implementation of an e-book. The paper could be helpful both for systems analysts and for teachers when they are developing and implementing e-books.

Optimal model through identified frequencies of a masonry building structure with wooden floors

The paper presents the analysis of an important historical building: the Saint James Theater in the city of Corfù (Greece) actually used as the Municipality House. The building, located in the center of the city, is made of carves stones and is characterized by a stocky shape and by the presence of wooden floors. The study deals with the structural identification of such structure through the analysis of its ambient vibrations recorded by means of accelerometers with high accuracy. A full dynamic testing was developed using ambient vibrations to identify the main modal parameters and to make a non-destructive characterization of this building. The results of these dynamic tests are compared with the modal analysis of a complex finite element (FE) simulation of the structure. This analysis may present several problems and uncertainties for this stocky building. Due to the presence of wooden floors, the local modes can be highly excited and, as a consequence, the evaluation of the structural modal parameters presents some difficulties.

Aprehender dibujando: los dibujos de Luis Borobio

Este artículo es una contribución al entendimiento del dibujo como aprehensión de su objeto, en general, y de la arquitectura, en particular, es decir, como definición de lo tangible que luego se materializará en la obra. Para ello, tomamos como referencia algunos dibujos de Luis Borobio (1924-2005), arquitecto y catedrático de Estética, poeta y caricaturista, que ilustran sus libros y cuyo valor, como apuntes a mano alzada, es el de dar a entender, de manera sencilla y eficaz, aquello que representan. De este estudio se desprende su capacidad para la transmisión de conocimiento, el sentido del boceto como metáfora y de la caricatura como crítica, herramientas con las que la mano llega a conocer y dar a conocer su objeto. Se añade una reflexión final sobre Mi árbol, verdadero manual de expresión gráfica, idóneo para contribuir a esclarecer la dialéctica entre masa y espacio que es propia de toda arquitectura.
