This paper presents a design technique of magnetic integrated LLCL filters for grid-tied inverters. With the proposed technique, filter's resonant frequency can be higher than Nyquist frequency. Furthermore, concept was only reported LCL filter in previous research works. In addition, modulation process will produce dominant switching harmonics unipolar PWM H-bridge inverters at double Thus, pu...

This note calculates the requirements on the anti-aliasing filter for the read-out of the fluorescence detector of the AUGER experiment. The filter order and its cut-off frequency are related to the error in amplitude reconstruction. 1 System transfert functions The Fluorescence Detector read-out channel consist of a current preamplifier followed by a low pass anti-aliasing filter and a samplin...

Abstract Biomethanation is a prospective biogas upgrading method to integrate renewable energy grid with existing grid. Biomethane can directly substitute fossil natural gas and be used in all sectors. The selection of packing material for the ex-situ biomethanation biotrickling filter reactors based on physical chemical characterization carrier material. selected supports hydrogenotrophic meth...

Double Boolean algebras are algebras (D,u,t, , ,⊥,>) of type (2, 2, 1, 1, 0, 0). They have been introduced to capture the equational theory of the algebra of protoconcepts. A filter (resp. an ideal) of a double Boolean algebra D is an upper set F (resp. down set I) closed under u (resp. t). A filter F is called primary if F 6= ∅ and for all x ∈ D we have x ∈ F or x ∈ F . In this note we prove t...

We investigate regular realizability (RR) problems, which are the problems of verifying whether the intersection of a regular language – the input of the problem – and a fixed language, called a filter, is non-empty. In this paper we focus on the case of context-free filters. The algorithmic complexity of the RR problem is a very coarse measure of the complexity of context-free languages. This ...

A robust recursive least-squares (RLS) adaptive filter against impulsive noise is proposed for the situation of an unknown desired signal. By minimizing a saturable nonlinear constrained unsupervised cost function instead of the conventional least-squares function, a possible impulse-corrupted signal is prevented from entering the filter’s weight updating scheme. Moreover, a multi-step adaptive...

In this study by using noise-free signal estimation the reduction of noise in the image is being proposed. The dyadic stationary wavelet transform is used for both the wiener filter and in estimating the noise free signal. Finding a suitable filter bank and choosing other parameters of the wiener filter with respect to obtained signalto-noise ratio (SNR) is our goal. Testing was being performed...

The articles [8], [5], [9], [1], [10], [11], [3], [2], [7], [4], and [6] provide the notation and terminology for this paper. We consider tree construction structures as extensions of 1-sorted structure as systems 〈 a carrier, rules 〉, where the carrier is a set and the rules constitute a relation between the carrier and the carrier∗. Let us note that there exists a tree construction structure ...

Free electron model, constructed by Drude and Lorentz near 1900 (well before quantum mechanics was developed), can qualitatively explain the DC electrical conductivity, AC electrical conductivity, Hall effect, and magnetoresistance. Later inclusion of Fermi-Dirac distribution (as opposed to Boltzmann distribution) helps to explain the thermal conductivity and specific heat of electrons. However...
