A comprehensive analysis of the occlusal plane (OP) inclination in predicting anteroposterior mandibular position (APMP) changes is still lacking. This study aimed to analyse relationships between inclinations different OPs and APMP metrics explore feasibility OP APMP. Overall, 115 three-dimensional (3D) models were reconstructed using deep learning-based cone-beam computed tomography (CBCT) segmentation, their accuracy supporting cusps was compared with that intraoral scanning models.

Microservice architecture (MSA) is a new software architecture, which divides large single application and service into dozens of supporting microservices. With the increasingly popularity MSA, security issues MSA get lot attention. In this paper, we propose an algorithm for mining causality root cause. Our consists two parts: invocation chain anomaly analysis based on robust principal component (RPCA) indicator detection algorithm. The composed Isolation Forest (IF) algorithm, One-Class...
Four new trigonometric Bernstein-like basis functions with two exponential shape pa- rameters are constructed, based on which a class of Bezier-like curves, anal- ogous to the cubic Bezier is proposed. The corner cutting algorithm for computing curves given. Any arc an ellipse or parabola can be represented exactly by using curves. corresponding operator presented and spectral analysis shows that closer given control polygon than cu- bic Based proposed basis, B-spline-like local constructed....
Constructing shape-preserving interpolation spline has been a hot topic in industrial design and scientific data visualization during the past 30 years. In existing shape preserving C2 methods, however, some methods can be only used to preserve monotonic set, while others convex often for continuity, it is requested solve linear system of consistency equations derivative values at knots. this paper, new explicit representation rational quartic with two local tension parameters developed. A...

In the classical GM(1,1) model, an accumulated generating operation is made on original non-negative sequence to obtain a monotone increasing 1-AGO sequence, and forecasting model established based sequence. A great number of scholars have improved accuracy grey prediction through better developed background value equation for time response. this work, we reconstruct new monotonicity-preserving piecewise cubic interpolations spline, thereby establish model. Numerical examples show that has...
Key performance indicators (KPIs) are time series with the format of (timestamp, value). The accuracy KPIs anomaly detection is far beyond our initial expectations sometimes. reasons include unbalanced distribution between normal data and anomalies as well existence many different types curves.
