Research on Innovation Ability of Industrial Clusters Based On the Fuzzy Comprehensive Evaluation Method ——In Case Of Si Chuan Software Industry Cluster
This paper was first based on the introduction of the fuzzy comprehensive evaluation method and the index system of innovation ability of industrial clusters, and apply the fuzzy comprehensive evaluation method to the cluster\u27s innovation capability for the scientific evaluation, then do the practical situation on the Sichuan Cheng du software industry cluster, obtaining the result is consistent with the practical situation. Therefore, using the fuzzy analytic hierarchy process can not only be on different clusters for horizontal comparison analysis, but also on different periods of the same cluster of longitudinal analysis, so as to clear the superiority and the insufficiency of clusters in the innovation, this method are meaningful for the evaluation of cluster\u27s innovation capability
Coupled Physics-informed Neural Networks for Inferring Solutions of Partial Differential Equations with Unknown Source Terms
Physics-informed neural networks (PINNs) provide a transformative development
for approximating the solutions to partial differential equations (PDEs). This
work proposes a coupled physics-informed neural network (C-PINN) for the
nonhomogeneous PDEs with unknown dynamical source terms, which is used to
describe the systems with external forces and cannot be well approximated by
the existing PINNs. In our method, two neural networks, NetU and NetG, are
proposed. NetU is constructed to generate a quasi-solution satisfying PDEs
under study. NetG is used to regularize the training of NetU. Then, the two
networks are integrated into a data-physics-hybrid cost function. Finally, we
propose a hierarchical training strategy to optimize and couple the two
networks. The performance of C-PINN is proved by approximating several
classical PDEs
Motion Control of Two Mobile Robots under Allowable Collisions
This letter investigates the motion control problem of two mobile robots
under allowable collisions. Here, the allowable collisions mean that the
collisions do not damage the mobile robots. The occurrence of the collisions is
discussed and the effects of the collisions on the mobile robots are analyzed
to develop a hybrid model of each mobile robot under allowable collisions.
Based on the effects of the collisions, we show the necessity of redesigning
the motion control strategy for mobile robots. Furthermore, impulsive control
techniques are applied to redesign the motion control strategy to guarantee the
task accomplishment for each mobile robot. Finally, an example is used to
illustrate the redesigned motion control strategy.Comment: 8 pages, 5 figure
