11. At that critical value of the parameter K, the system undergoes a Hopf bifurcation. 12. There is a critical value of transformer gain is maximum at the resonant frequency. 13. There is no very special critical value in the readings. 14. A-segregates are predicted to form when the Rayleigh number exceeds a certain critical value . 15. The critical value is found from the t-distribution table. 16. If the value of the field exceeds some critical value , the latter changes its direction. 17. Thus these polynomials have only two finite critical values , the defining property of Shabat polynomials. 18. However, criticality is only achieved once the thickness of this slab exceeds a critical value . 19. Eventually, at an unknown critical value of ?, there is a transition to quark matter. 20. The SAS and R-package MBESS provides functions to find critical values of " ncp ".
