Studies have shown that Sentinel-2 images have advantages over Landsat images in impervious surface area (ISA) extraction. The performance of index-based methods can be affected by different binary ...

The results are compared to the ones obtained with the FEM using linear elements and a Hierarchical Finite Element Method (HFEM) using higher order elements. Keywords: dynamic analysis, structural ...

To grasp various non-cooperative objects in space, this paper develops a novel truss-shaped deployable manipulator with double scissor-shaped mechanisms, which consists of multi-fingers and a ...

Alex Kachkine spends his days working on microchip research — a skill set surprisingly similar to that needed for restoration.
