Abstract: Semiconductor light-emitting devices are provided, which includes a substrate, a Negative-type semiconductor, a quantum well, an electron-blocking layer, and a Positive-type semiconductor arranged in a sequential stack. The quantum well includes a first quantum well, a second quantum well, and a third quantum well. Optical parameters of the first quantum well, the second quantum well, and the third quantum well are distributed in a gradient in at least one direction. The quantum well includes a periodic structure consisting of a well layer and a barrier layer. A coefficient of thermal expansion of the well layer is smaller than or equal to that of the barrier layer. An elastic coefficient of the well layer is smaller than or equal to that of the barrier layer. A lattice constant of the well layer is greater than or equal to that of the barrier layer. A coefficient of spontaneous polarization of the well layer is smaller than or equal to that of spontaneous polarization of the barrier layer.

Abstract: In one instance, disclosed herein is a computer-implemented method for monitoring an undercarriage of a track-type machine, the computer-implemented method comprising: accessing a reduced order model (ROM) corresponding to the track-type machine; receiving an estimated wear level of at least one undercarriage component of a track-type machine and machine signal data generated by the track-type machine; generating an updated estimated wear level of the at least one undercarriage component using the estimated wear level, the machine signal data, and the ROM; and comparing the updated estimated wear level of the at least one undercarriage component to a wear level threshold.
