... for engineering computation (Bellman et al., 1972 ; Bert and Malik, 1996 ; Malik and Civan, 1994). As a high order discretization technique, it provides very accurate results with reasonably small number of sampling points. It is particularly useful in eigenvalue problem of mechanical structures (e.g...

... the eikonal transformation has been used in the theory of nonlinear optics, this is the first time it has been utilized for effective engineering computations. Although both equations (2.9), (2.10) and (2.13), (2.14), or (2.11), (2.12) and (2.15), (2.16), offer relatively simple algorithmic structures...
