In order to improve the feasibility of low-elevation height measurement for meter-wave multiple-input multiple-output (MIMO) radar, a virtual sub-array-level beam splitting algorithm is proposed. The can solve coherence problems caused by low-angle multipath reflection, target reflection wave and direct coupling, quickly measure low elevation angle on flat ground, then obtain through geometric ...

Corn height measured manually has shown promising results in improving the relationship between active-optical (AO) sensor readings and crop yield. Manual measurement of corn height is not practical in US commercial corn production, so an alternative automatic method must be found in order to capture the benefit of including canopy height into in-season yield estimates and from there into in-se...

BACKGROUND A clinical need exists to improve identification of those who will sustain fragility fractures. Individuals with both osteoporosis (OP) and sarcopenia (SP), so-called "sarco-osteoporosis" (SOP), might be at higher fracture risk than those with OP or SP alone. Approaches to facilitate SOP identification, e.g., use of tallest historical rather than current height and inclusion of radiu...
