The worldwide adoption of the Internet Things (IoT) depends on massive deployment sensor nodes and timely data collection. However, installing required ground infrastructure in remote or inaccessible areas can be economically unattractive unfeasible. Cost-effective nanosatellites deployed low Earth orbits (LEOs) are emerging as an alternative solution: on-board IoT gateways provide access to de...

In materials science, the microstructures of are generally characterized by 2D observation (e.g. electron microscopy). For polycrystalline materials, such as crystalline rocks or ceramics, those observations can be used to measure grain size distribution. However, fact that sizes measured in planar cuts introduces a statistical bias, since real (3D) cannot directly measured. almost spherical gr...
