We propose an opportunistic routing scheme for wireless sensor networks operating in volatile environments. In particular, we consider a sensor field for sensing and reporting on buildings during fires, where sensors are progressively being destroyed by the fire. We envisage firefighters equipped with small computers which can act as mobile sink nodes, offering transient shorter routes for rela...

Archeological acoustics is a part of acoustics that studies ancient environments which were dedicated (completely or partly) to sound performing. The combination of this acoustic area in conjunction with room acoustics enables the study of the acoustic evolution of existing buildings (in terms of the historical documentation) or even, make the acoustic reconstruction of rooms which were destroy...

In recent years, the acquisition and processing techniques of high resolution Digital Surface Models (DSM) have been rapidly improved. Airborne LiDAR production as a well-known and high quality DSM is still unbeatable in elevation accuracy and highly produced dense point clouds. In this paper, the objective is to update an old but high quality DSM produced by LiDAR data using a DSM generated fr...

The legacy of Arab-Muslim architecture in Spain is one of the most valuable parts of the wealthy Spanish heritage. The application of new concepts and practices to the conservation of this architecture has led to numerous examples of restoration which respect historical values, while using the most modern techniques and principles at the same time. Nowadays, virtual reconstruction of buildings ...

Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...

3D building data is needed in many application areas. Besides the geometric description an increasing number of applications also demand thematic information about acquired buildings. We present a concept for the automatic extraction of buildings from aerial images. In contrast to other approaches generic building structures both are geometrically reconstructed and semantically classified. A co...

Earthquakes, as a nature disaster, not only causes deaths, physical disease, damage to the infrastructure and economic loss, it also keeps long-lasting Mental Health effects on individuals involved. There will always be cases of psychological disorders such as PostTraumatic Stress Disorder (PTSD), depression, cognitive disorder, personality disorders, and so on, especially with individuals deal...

Historical perspective images have been proved to be very useful to properly provide a dimensional analysis of buildings façades or even to generate a pseudo-3D reconstruction based on rectified images of the whole structure. In this paper, the case of Gobierna Tower (Zamora, Spain) is analyzed from a historical single image-based modeling approach. In particular, a bottom-up approach, which ta...

The virtual recreation of a physical three dimensional (3D) exhibition or museum allows a visitor to navigate in this virtual scenario in a way closer to reality. This issue is particularly relevant when the museum building is by itself a piece of art, as it is often the case. In this paper, the use of virtual 3D models in the domain of cultural diffusion is analysed, considering the common asp...

The components and claddings of low-rise building are usually destroyed first during typhoon disasters in coastal areas. Roof accessory structures can change the flow pattern on the roof, thus effectively reducing the wind load on the roof surface and the damage to the low rise buildings. Two types of aerodynamic mitigation plates, i.e., (1) 0.3 m high full length roof-edge plate, and (2) 0.3 m...
