To solve the clinical problem of constructing an aesthetic and appropriate orbital prosthesis model, two methods based on volume cutting and surface cutting respectively are proposed in this paper. Using spline interpolation, region growth, triangular patch calculation, cylinder cutting and other techniques, we obtain the 3D orbital prosthesis model with a proper size and smooth edges. Besides, a...
In order to solve the parallel algorithm for Petri nets system with concurrent function, to realize the parallel control and execution of the Petri nets, the Petri nets parallel subnets conditions were proposed, that provides the theory basis for judging P- invariant whether was the parallel subnet. Firstly, we according to the concurrent character of Petri net model, to analyze the parallelism of...
With the aim of solving the problems of the Petri nets to the place/transition nets automatic conversion and realization of Petri nets parallel control and running, the algorithm is proposed to transform Color Petri net systems transform into P/T nets. The algebraic model of colored Petri nets and P/T nets, and its intrinsic mechanism is analyzed, the process and theory verification of the colored...
A recent lifting technique led to a computationally efficient Model Predictive Control (MPC) strategy in which the online optimization is performed using a univariate Newton-Raphson procedure. However this procedure solves a dual problem, preventing the use of warm starting or premature termination. By solving a primal problem, the current paper proposes a strategy that is more efficient than the...
A recent paper proposed an MPC methodology which achieved a considerable reduction in the online optimization by transferring some of the computational load to calculations that can be performed offline. The approach was based on an augmented autonomous state space formulations of the prediction dynamics and gained significantly in efficiency by imposing a terminal constraint at current time. The...
