This work focuses on improving the technical and economic performance of poultry farming sub-sector in Benin. We were specifically interested study design a grinder-grader for feed. Indeed, two different technologies controlling particle size are combined into one to form crusher-sizer. is fragmentation food particles, carried out by mobile hammer mill dimensional classification vibrating sieve...

For entomological radar, the polarization information of target is usually used to estimate biological parameters, such as orientation, body length, and mass, insect. Thus, accuracy measurement directly affects performance parameters’ estimation. The error mainly caused by imbalance amplitude phase between two channels crosstalk dual-polarization antenna. In order obtain correct target, polarim...

ABSTRACT A good knowledge of the angular diameters stars used to calibrate observables in stellar interferometry is fundamental. As available precision for giant worse than required per cent level, we aim improve many using MATISSE (Multiple AperTure mid-Infrared SpectroScopic Experiment) data its different instrumental configurations. Using squared visibility observable, compute diameter value...

Traditionally, fully polarimetric calibration of a nonreciprocal radar system requires measurements at least two passive calibrators, such as dihedral corner reflector plus metal plate or sphere. Interchanging multiple calibrators results in not only higher complexity but also degraded uncertainty. In this work, new calibrator is proposed, which designed quarter concave cylinder linked (QCCLD)....
