Background
Whether the accuracy of robot‐assisted spinal screw placement is significantly higher than that of freehand and the source of robotic deviation remain unclear.
Methods
Clinical data of 105 patients who underwent robot‐assisted spinal surgery was collected, and screw accuracy was evaluated by computed tomography according to the modified Gertzbein–Robbins classification. Patients were...
Facial expression recognition is an interesting research topic. Considerable methods have been proposed in order to achieve high accuracy in facial expression recognition, however, only a few of these methods have considered factors like memory consumption and computational complexity. In this paper, we focus on smile detection which belongs to facial expression recognition. Compare with the proposed...
General fuzzy controller in the control rules to determine the need, after adjustment, time-consuming and laborious; with a correction factor of fuzzy controller to change the correction factor, the entire control of the table almost affected, would make some point to meet the control requirement has led to some point does not meet the requirements. To solve these problems, proposed a new type of...
This paper studies the real-time location of human body and objects in indoor environments of several methods, and through reverse thinking, study of a RFID-based indoor signal blocking method for positioning, according to the experimental thinking, we did a reality scenario test, obtained relevant data. According to test results we obtained the optimum label release interval, which to provide support...
Generally, the code excited linear predictive (CELP) coding is known as one of the best algorithms for bit rate between 4 kbps and 16 kbps. Recently, the algebraic CELP (ACELP) algorithm has been widely adopted in standard speech coders such as G.729 and Adaptive multi rate (AMR) and AMR Wide Band (AMR-WB).In order to improve the speech quality based on CELP algorithm, harmonic Pitch pre-emphasis...
