Trigonometric approximation

This paper proposes a simple current balancing method among phases for three-phase Dual-Active-Bridge converters due to inductance mismatch in the transmission path. The method is based on first harmonic approximation and trigonometric calculation of the phase shift for each phase. Simulation and experimental results show that the proposed method can help balance the phase current effectively

A unified higher-order shear deformation theory for static analysis of laminated composite beams is proposed in this paper. The theory is based on a higher-order shear deformation beam theory in which a general shear function is proposed. The characteristic equations are derived from Lagrange’s equations and then Ritz method is used to determine the stiffness matrix.

In the present work we prove some direct and inverse theorems for approximation by trigonometric polynomials in Musielak–Orlicz spaces. Furthermore, we get a constructive characterization of the Lipschitz classes in these spaces.

Main properties of the mixed modulus of continuity in the Lebesgue spaces with Muckenhoupt weights are investigated. We use the mixed modulus of continuity to obtain Potapov type direct and inverse estimates of angular trigonometric approximation of functions in these spaces.

The purpose of this volume is to give some guidelines for the student concerning the solution of problems in the theory of Functions in Several Variables. The intension is not to write a textbook, but instead to give some hints of how to solve problems in this fi eld. It therefore cannot replace any given textbook, but it may be used as a supplement to such a book on Functions in Several Variables.

Function Evaluation Algorithms Commercially available DSP processors are designed to efficiently implement FIR, IIR, and FFT computations, but most neglect to provide facilities for other desirable functions, such as square roots and trigonometric functions. The software libraries that come with such chips do include such functions, but one often finds these general-purpose functions to be unsuitable for the application at hand. Thus the DSP programmer is compelled to enter the field of numerical approximation of elementary functions....
