S.G. Nikolov, E. Loke, J.M.H. du Buf Signal and Image Processing Laboratory Department of Electronics and Computer Science University of Algarve, 8000 Faro, Portugal e-mail: fsnikolov, loke, [email protected] ABSTRACT In this paper we describe a new software system for interactive three-dimensional visualisation of sonar data. Novel approaches to 3-D volumetric sonar data reconstruction and segmen...
the images of muslims in media, literature and politics have been mostly black and white portrayals of a people alien to modernity, civilization, rationality and pluralism. since the end of the cold war and the onset of deadly terrorist attacks in different areas of the world, especially in the united states, these representations show a palpable difference: muslims are represented not only as ...
Three-dimensional geoelectrical surveys are widely used to map the subsurface in areas with complex geology. Field survey methods using offset pole–dipole and dipole–dipole arrays have been proposed large efficiently. However, it has found that negative apparent resistivity values sometimes encountered contrasts, particularly when offsets between current electrodes potential dipoles used. The v...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

One of the slopping processes which creates tremendous damage in many locations of Iran and the world is landslide phenomenon. Creating a landslide susceptibility map provides the possibility to recognize susceptible areas and to verify them in the environmental programs. The purpose of this research is to map the susceptibility of landslide in Taleghan watershed by establishing informational l...
in this research, the applicability of geographic information system (gis) and remote sensing (rs) techniques was tested to assess soil erosion risk with the icona erosion model. this study was carried out in the tange bostanak area because of its variety of diverse landforms, land uses and land covers. the erosion risk assessment phase of this model consists of seven steps that mainly use slop...
Landslide, due to its dangerous nature in mountainous areas, usually causes morphology to suddenly collapse and causes major damage to residential areas, roads, agricultural lands, and so on. In this study, using the AHP model and fuzzy logic operators, we evaluated and zoned the landslide sensitivity in the Pseudogene basin in Razavi Khorasan province. The eight main criteria of elevation, slo...
This paper summarizes the results of a recent geophysical investigation carried out at Porolissum, which is considered to be one most significant Roman sites in Romania. The survey was within latus dextrum fort, same location that had been subject earlier surveys as well older archaeological excavations (1970s) uncovered multiroom building. A cesium vapor total field magnetometer and multi-elec...
The Yeoncheon titanomagnetite deposit formed by Precambrian magma differentiation is located in Gyeonggi-do, South Korea. Our team conducted an airborne magnetic survey for multiscale mineral exploration and then selected a promising area. An electrical resistivity was carried out the potential area to image subsurface structure. Because ore minerals are mainly distributed gabbro monzodiorite r...
