Self-Compensation of Commutation Phase Error for Brushless DC Motor
Abstract: BLDC motors are synchronous motors powered by DC electricity via an inverter which produces an AC electric current to drive each phase of the motor via a closed loop controller. Electronic commutation is the on-and-off of the semiconductor switches at appropriate time to turn stator windings. Commutation phase ripple is generated due to the different exchange rate between outgoing phase current and incoming phase current of inverter during commutation period. …

Managing Pavement Settlement Risk: Impact of Waterlogging and Soil Conditions
Abstract: In the context of road infrastructure, the occurrence of waterlogging due to rainfall can have significant repercussions. Rainwater often infiltrates the road surface and, depending on factors such as the depth of the foundation and the extent of penetration into the ground, can lead to the soil beneath the road becoming either moist or saturated. This, in turn, can result in a reduction of the soil's bearing capacity. When vehicles …
