Simultaneously, for each process of extrusion it was possible to assess the angles of convergence to the bottom of the chambers for both the external and internal chambers.
Secondly, the influence of system state noise and observation noise were taken into account, designed a stochastic sliding model variable structure guidance law, which had the merit of robustness and angle of sight convergence.
By focusing only on one parameter, which was the inlet angle of the convergence nozzle, Khan et al. [19] studied the flow patterns through the velocity and pressure behavior contours.
Several experimental studies in close-range photogrammetry have revealed that the accuracy of a network increases with the increase of convergence angles of cameras, the numbers of intersection rays to an object point, the number of measured points, and orthogonal roll angles (Fraser 1996b; Fryer 1996; Clarke et al. 1998; Gruen and Beyer 2001; El-Hakim et al. 2003; Remondino and Fraser 2006).
In addition, increasing the volumetric flow rate of coolant and convergence angle of channels, reduced the temperature gradient in bottom wall of the heat sink.
To investigate the influence of the convergence angle of tooth preparation on the fracture load of Y-TZP-based ceramic (YZ – Vita YZ) substructure (SB) veneered with a feldspathic porcelain (VM9 – Vita VM9).
Within the limitations of this experimental design, decreasing the axial convergence angle of the ceromer/fiber-reinforced composite crowns diminished their marginal gap and increased their fracture strength.
With the limitation of acceptance angle and crystal growth size are taken into account, the tiling scheme of LBO crystals is proposed and designed optimally to adopt to the total convergence angle of 36.0 mrad.
While varying the convergence angle of the duct it is observed that the maximum power coefficient and lowest torque ripple are obtained at the same value of duct half angle, equal to 27°.
This study aimed to individually quantify the effects of various design parameters, including margin thickness, convergence angle of abutment, and bonding conditions on fracture resistance of resin bonded glass dental crown systems (namely, glass simulated crown).
