A high efficiency and low audio noise motor includes an armature (Figure 5) and a stator (Figure 6). The armature has an armature aspect ratio which is equal to the armature diameter (DA) divided by the armature thickness and is not less than three. The stator has a stator aspect ratio...

Wood chips to be separated are metered by an auger into the separation chamber where the high velocity air stream disperses the chips evenly over the chamber. The more dense knots fall through the uprising current of air and are rejected. The lighter chips are drawn from the separation ...

(total acceleration, body acceleration, total angular velocity, and both time and frequency domain features). The WISDM dataset uses only the original acceleration and rotation features. Accuracy on the HAR dataset (Fig.3) is generally higher in the 89%-92% range compared to the similar task ...
high velocity + low mass and low velocity + high mass. Damage caused by the two groups of experiments and peak forces measured were dissimilar. The results show that the addition of 5 wt.% of nanoclay lead to a more efficient energy absorption. The failure modes were also analyzed, and ...

Conventional light-emitting diodes (LEDs) face an efficiency droop at low current due to non-radiative recombination overtaking radiative recombination at low carrier density. To overcome this universal problem, we develop LEDs with high efficiency at ul
