One novel composite kernel based support vector machine (SVM), which is called DOCKSVM (Data Oriented Composite Kernel based Support Vector Machine) is proposed in the paper. SVM have been proved good potential in various studies, and tried to application for pattern classification problems such as text categorization, image classification, objects detection etc. Recently, more and more researc...
Integrated use of multidisciplinary researches have been applied in the last years for the study of Aquileia archeological sites and, in particular the River Port structures. Since 1992 GPS (Global Positioning System) techniques have been adopted with the aim of linking together various independent topographic networks and georeferencing single relevant points. In 2001 a scientific cooperation ...
In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by scientists of Riga Technical University (RTU). The model generalizes geological and hydrogeological information accumulated by the Latvian Environment, Geology and Meteorology Center (LEGMC). LAMO simulates the active groundwater zone that provides drinking water. The worldwide used commercial program Groundwater Vis...
The 10-year drought event from 2007 to 2017 caused a completely different behavior of groundwater of the Ilam-Sarvak karstic aquifers in northern Khuzestan in two regions Izeh (with a drop of about 120 meters) and Lali (with a drop of about 20 meters). In this paper, the drawdown in the Izeh karstic aquifers and the reduction of discharge of karstic wells are compared to the Lali aquifer based ...
The study of the human past needs the effort of different disciplines including history, archaeology and non invasive imaging techniques such geophysics whose application for cultural heritage has been dramatically increasing in the last two decades. The capability of geophysical techniques in identifying subsurface features of cultural interest depends on: 1) the nature of the physical interac...
Old Las Salinas spring in Medina del Campo, Duero river basin, central Spain. Campo groundwater body (MCGWB) is a multilayer semiconfined aquifer subject to intensive pumping since the 1970’s, where current existence of spas there used be traditional baths could confirm deep flow paths. The old (OSLS) saline anomaly an with predominance CaCO3H waters whose occurrence has not yet been formally e...
vodeAbstractThe Radovna River Valley is located in the north-western part of Slovenia Julian Alps, where there an extensive intergranular aquifer whose depth to pre-Quaternary bedrock unknown. Therefore, obtain information about valley and geometry two geophysical methods were used our study; ground penetrating radar (GPR) seismic reflection method. The low-frequency GPR method has shown be use...
Groundwater nitrate contamination of the aquifer in the Central Valley, California is a major problem due to intense agricultural practice over the last decades. Excessive loading of fertilizer and manure in combination with hydrogeological parameters and geochemical conditions have enhanced the downward percolation of nitrate into the aquifer. A spatial variance-based geographical detector met...
