[1] We explore and review the value of soil moisture measurements in vadose zone hydrology with a focus on the field and catchment scales. This review is motivated by the increasing ability to measure soil moisture with unprecedented spatial and temporal resolution across scales. We highlight and review the state of the art in using soil moisture measurements for (1) estimation of soil hydrauli...

In this work we present an evaluation of the performance of a range-based hybrid localization algorithm based on the Received Signal Strength Indicator (RSSI) and inertial data applied in a real world WSN. As can be found in literature, RSSI-based localization algorithms exhibit low accuracy due to the variability of the radio signal. Adding inertial information, such as accelerations values ob...

the soil erodibility factor varies spatially according to variations of some soil properties on the surface. this study was carried out to compare spatial variability of the soil erodibility factor as estimated and measured using the usle. the study was conducted in an agricultural zone with an area of in 900 km2 in hashtrood, northwestern iran. in the study area, 36 square grids with a dimensi...

In direct seeding systems, soil strength variability and crop residues increase the difficulty of seeding operation. Especially when trying to achieve uniform seeding depth that will result in reliable seed germination and plant emergence. An advanced improvement has been accomplished using direct seeding systems. However, some problems still exist in soil-machine interaction due to various rea...

We describe how to build statistically-based flexible models of the 3D structure of variable objects, given a training set of uncalibrated images. We assume that for each example object there are two labelled images taken from different viewpoints. From each image pair a 3D structure can be reconstructed, up to either an affine or projective transformation, depending on which camera model is us...
