31. The approximation u _ h can be computed by solving a linear system of equations. 32. Finite element simulations of moderate size models require solving linear systems with millions of unknowns. 33. Its linear subspaces are called linear systems of divisors. 34. However, a standard linear system has yet to emerge. 35. The addition of noise to a linear system will always decrease the information transfer rate. 36. One then constructs a linear system that can then be solved by standard matrix methods. 37. He was a pioneer in the field of applied mathematics : non-wave replicating linear systems . 38. So in practice, an approximation that results in linear systems of equations is often used. 39. The popular trend in trench drains are linear systems . 40. The main limitation of response spectra is that they are only universally applicable for linear systems .
