Electrical resistivity tomography and induced polarization studies were conducted for groundwater exploration in eight selected agricultural sites Brunei Darussalam. The study was undertaken to meet the growing demands water supply sector, particularly paddy field irrigation purposes. This nineteen surveys with lengths of up 800 m a depth investigation 150 below ground level. 2D inverted charge...

A novel mobile peer-to-peer (MP2P) in cellular networks is presented in this paper. The proposed architecture is based on Session Initiation Protocol (SIP) that is part of the IP Multimedia Subsystem (IMS) in the third-generation mobile cellular networks. In this architecture, P2P control messages are transported in SIP messages, so called P2PoverSIP. By way of SIP, the operators can have contr...

Currently, with the quick increase in global population, energetic crisis, environmental problematic, and development of power electronic devices generated need to include new technologies for supporting potentiating electrical distributions systems; Distribution Static Compensators (D-STATCOMs) are highly used this task due advantages that technology presents: reduction loss, operation costs, ...

This work analyzed the effectiveness of two electrical geophysical methods in characte-rizing tailings dams. A large flotation cell used for sludge thickening concentration plant Federico Mine (closed 1985) within old mining district La Carolina (southeastern Spain) was selected this research. In addition to direct information provided by geology study area and surface exposure waste deposits, ...

Abstract Wood moisture content (MC) has a significant impact on all electrical properties of wood. Regarding the development (so-called polarization-type) wood meter with charging effect for monitoring and controlling drying process, it is interest to expand theoretical background this type novel by means modelling. Two mediums were selected modelling – raw birch and, as reference medium, liqui...

SUMMARY Kilauea is an active shield volcano located in Hawaiʻi. An induced polarization survey was performed 2015 at the scale of caldera. The data were acquired with a 2.5 km cable 64 electrodes and spacing 40 m between electrodes. A total 6210 measurements performed. apparent chargeability inverted using least square technique to obtain tomogram. normalized tomogram obtained by multiplying ce...

The Alta Floresta Gold Province (PAAF) is abundant in gold deposits and, located the state of Mato Grosso, Brazil, an ideal place to study geoelectric signature mineralization. Auriferous mineralization occurs along shear zones quartz veins and disseminated granites this region. Ores are associated with oxides sulfides, mainly pyrites. To identify primary or continuities mineralized zones, data...
