this ethnography is a dialogic ethnography between field and two researchers. dialogic ethnography or dialogic anthropology was a result of textual revolution in discipline. textual or interpretive anthropology has been definition of culture as text founded in 1970s and 1980s. geertzian textual revolution considered and interpreted events and actions as texts. marcus, clifford, rabinow, crapanz...

The 3D model reconstruction of buildings from uncalibrated photographs allows new useful Computer Graphics and Computer Vision applications. In this paper we survey some solutions proposed in literature and in commerce. The common and different methodology are reported and described. Finally we try to address the 3D reconstruction problem of architectural scenes presenting our solution: BolBol....

The cavability assessment of rock mass cavability and indicating the damage profile ahead of a cave-back is of great importance in the evaluation of a caving mine operation, which can influence all aspects of the mine operation. Due to the lack of access to the caved zones, our current knowledge about the damage profile in caved zones is very limited. Among the different approaches available, p...

the sofeh mountain in the south of isfahan (iran) has a development of shafts (vertical cave). simorgh cave with a depth of 42 m and a length of 52 m has developed along significant fault structures. structural analysis indicates relationships of orientation between the faults and fractures and shafts and chambers geometries. considering the main ne-sw trend of tectonic structures in the area, ...

Gammarus minus, a freshwater amphipod living in the cave and surface streams in the eastern USA, is an excellent model for investigating evolutionary adaptation to the subterranean environment. RNA-Seq was conducted on one pair of morphologically distinct sister populations inhabiting surface and cave habitats to identify genes that were differentially expressed in the two populations, as well ...

Karstand cave-systems are complex, 3-dimensional phenomena. Mapping and visualizing them represents a challenge to cartographers, morphologists and computer-graphics-specialists. Surveying and sketching of cave-maps as well as the construction of 3D-cave-models (incl. geology) are important parts of cave exploration and research. Besides supporting the efforts of speleologists, cave maps and 3D...

Conventional wisdom among cave divers is that submerged caves in aquifers, such as in Florida or the Yucatan, are unstable due to their ever-growing size from limestone dissolution in water. Cave divers occasionally noted partial cave collapses occurring while they were in the cave, attributing this to their unintentional (and frowned upon) physical contact with the cave walls or the aforementi...

This paper introduces a Natural User Interface (NUI) that enables interaction in a Cave Automatic Virtual Environment (CAVE). The tracking of the head and hand in a CAVE usually takes place with the help of magnetic tracking systems or marker-based optical tracking systems. In both cases the user has to wear a number of instruments. In contrast, the CAVE at the HTW Berlin uses two depth detecti...
