Digital soil mapping (DSM) has been used from the national to paddock scale in Australia over past 20 years. However, there insufficient objective evaluation of limitations DSM. The continual evolution DSM methods time have led a lack operational stability that creates an ongoing risk associated with method. inherent modelling paradigm (a reliance on systematic variation) is key factor potentia...

Digital terrain models (DTM) have been used in soil mapping worldwide. When using such models, improved predictions are often attained with the input of extra variables provided by the use of proximal sensors, such as magnetometers and portable X-ray fluorescence scanners (pXRF). This work aimed to evaluate the efficiency of such tools for mapping soil classes and properties in tropical conditi...

presence of joints and fractures in rocks strongly influences the behavior of the rock mass by dividing the media into smaller units. these structures intensify the potential instability besides the development of sliding and rotational movements. the assumption of discontinuum media changes the whole analysis conditions in relation to the continuum analysis. acquisition of geometrical and stru...

introduction:  the  success  of  hyperthermia  depends  on  the  accuracy  of  the  temperature  monitoring in the tumor and the surrounding normal tissue. in this study, the temperature changes  were determined by computing the speckle displacement in the ultrasound digital images. speckle  tracking algorithm was used to compute the displacement.  materials and methods: the experiment was perf...
