Purpose
To evaluate the accuracy (trueness and precision) of reduction depths of guided veneer preparation assisted by four tooth preparation guides.
Materials and Methods
Fifty resin artificial teeth were randomly divided into five groups (n = 10): a freehand group (F), silicone guide group (S), thermoplastic guide group (T), 3D printed uniform guide group (D), and 3D printed auto‐stop guide group...
Online power measurement is one of the power measurements in smartphones which would allow us to measure the energy consumption of smartphones without using external devices. This online method depends on a built-in BMU (Battery Monitoring Unit). BMU is a chip which can gather relative data of the battery and submit them to the upper level. The current data which BMUs submit in the past is the average...
A new technique for quickly assessing extensive areas of mining subsidence that uses digital elevation models (DEMs) extracted from LiDAR (Airborne light detection and ranging, LiDAR) is presented in this paper. The proposed technique observes the elevation changes by using multi-temporal DEMs. One-meter-resolution DEMs from LiDAR data are applied to detection the mining subsidence in Hebi coal mine...
In order to improve the accuracy of the harmonic current compensation for the single-phase shunt active power filter, a compound control strategy is proposed with the PI control and repetitive paralleling based on the stationary frame, PI control is used to guarantee the system dynamic performance, the repetitive control is to improve the output current tracking accuracy for the load harmonic current...
