11. Computing acceptance probability can be reduced to solving a linear system . 12. In more recent work, Birkar studied Fano varieties and singularities of linear systems . 13. The theorem has been proved for linear systems comprising real vectors x and y. 14. In 1952 founded Non-Linear Systems , a manufacturer of digital instrumentation. 15. The canonical form may be viewed as an explicit solution of the linear system . 16. "And unlike linear systems , it requires no transfers, " says Raytheon engineer Steven Gluck. 17. The linear systems approach oversimplifies the dynamics of nonlinear systems. 18. Nonlinear systems can exhibit a substantially richer variety of behavior than can linear systems . 19. One has to see that the linear system is homogenous. 20. For linear systems , distortion-limited operation is equivalent to bandwidth-limited operation.
