Wavelet based spectral finite element for analysis of coupled wave propagation in higher order composite beams

In this paper, a spectrally formulated wavelet finite element is developed and is used to study coupled wave propagation in higher order composite beams. The beam element has four degrees of freedom at each node, namely axial and transverse displacements, shear and contraction. The formulation is used to perform both frequency and time domain analysis. The formulation is similar to conventional...

Modal Characterization using Principal Component Analysis: application to Bessel, higher-order Gaussian beams and their superposition

The modal characterization of various families of beams is a topic of current interest. We recently reported a new method for the simultaneous determination of both the azimuthal and radial mode indices for light fields possessing orbital angular momentum. The method is based upon probing the far-field diffraction pattern from a random aperture and using the recorded data as a 'training set'. W...

Unital Versions of the Higher Order Peak Algebras

We construct unital extensions of the higher order peak algebras defined by Krob and the third author in [Ann. Comb. 9 (2005), 411–430.], and show that they can be obtained as homomorphic images of certain subalgebras of the Mantaci-Reutenauer algebras of type B. This generalizes a result of Bergeron, Nyman and the first author [Trans. AMS 356 (2004), 2781–2824.].

Higher-order Rewrite Systems and Their Connuence

We study Higher-Order Rewrite Systems (HRSs) which extend term rewriting to-terms. HRSs can describe computations over terms with bound variables. We show that rewriting with HRSs is closely related to undirected equational reasoning. We deene Pattern Rewrite Systems (PRSs) as a special case of HRSs and extend three connuence results from term rewriting to PRSs: the critical pair lemma by Knuth...

Higher Order Methods and their Performance

A class of primal dual interior point methods is developed These methods use a higher order Taylor polynomial to approximate a primal dual trajectory de ned from an infeasible point A detailed implementation of these methods is given and their computational performance is studied We give computational results for two di erent approaches for de ning trajectory and using up to th order polynomial...
