The paper presents the DQ axis with Fourier analysis (DQF) algorithm to identify harmonic quantities for hybrid power filters. This algorithm is a combination of the advantages of DQ axis method and sliding window Fourier analysis (SWFA). This paper also presents the harmonic elimination by using the DQF algorithm for both three-phase balanced and unbalanced systems. The results show that the u...

Point Spread Function (PSF) engineering by pupil filters is a relevant technique in several applications, such as confocal microscopy, optical data storage and astronomy. Circularsymmetric filters have been usually preferred for the ease of their fabrication and analysis. A seminal study on such filters was performed by Toraldo [1]. Sheppard [2] introduced the parabolic approximation of the PSF...

Discrete diagnosis systems have traditionally included the ability to model unknown faults. However, this ability has not been available in hybrid diagnosis approaches. This is because one weakness of the standard approaches to tracking the hybrid state—Kalman filters and particle filters—is that it is hard to tell when they are performing poorly. In this paper we show that by using a particle ...

This novel joint feature issue on "Hybrid organic-inorganic materials for photonic applications" in Applied Optics and Optics Materials Express comprises 14 papers on liquid crystals, polymers, photoconductive materials, and gratings and filters. It is hoped that this feature issue encourages and stimulates further research into hybrid materials with enhanced linear and nonlinear optical proper...

In this paper obligatory hybrid networks of evolutionary processors (a variant of hybrid networks of evolutionary processors model) are proposed. In the obligatory hybrid network of evolutionary processors a node discards the strings to which no operations are applicable. We show that such networks have the same computability power as Turing machines only using one operation per node (deletion ...
