11. The symmetrical network theory has been developed with the assistance of mathematical modeling. 12. The classical application area for network theory and Tellegen's theorem is electrical circuit theory. 13. His research focuses on network theory , dynamical systems, and multiphysics modeling of complex systems. 14. Actor-network theory has developed this concept as the object around which social networks form. 15. The vaccine concept was based on a network theory resolution of the Oudin-Cazenave paradox. 16. But Le Soir said it had seen no evidence to support the network theory . 17. Matroids have found applications in geometry, topology, combinatorial optimization, network theory and coding theory. 18. Instead, we borrow from network theory and calculate scattering matrices. 19. Immune network theory became, and remains, Hoffmann's primary research focus. 20. This image appears at Bose Einstein condensation ( network theory ) with the same caption.
