Developed a control system based on reckon up track distance for a variable rate fertilizer applicator without GPS. The control system is able to read the velocity sensor's pulse signal, calculate the ground speed and track distance of the fertilizer applicator, and recognize the working grid by means of the algorithm of automatic grid recognition after(More)
We have investigated the structural and optical properties of type-II GaSb/InGaAs quantum dots [QDs] grown on InP (100) substrate by molecular beam epitaxy. Rectangular-shaped GaSb QDs were well developed and no nanodash-like structures which could be easily found in the InAs/InP QD system were formed. Low-temperature photoluminescence spectra show there(More)
