The orthosymplectic Lie supergroup in harmonic analysis [PDF]

open access: yes, 2010
The study of harmonic analysis in superspace led to the Howe dual pair (O(m) x Sp(2n); sl2). This Howe dual pair is incomplete, which has several implications. These problems can be solved by introducing the orthosymplectic Lie supergroup OSp(m|2n).

On an atomic decomposition in Banach spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
An atomic decomposition is considered in Banach space.  A method for constructing an atomic decomposition of Banach  space, starting with atomic decomposition of  subspaces  is presented. Some relations between them are established.

Harmonic analysis

open access: yes2004 IEEE Electro/Information Technology Conference, 2004
This paper describes a method of calculating the transforms, currently obtained via Fourier and reverse Fourier transforms. The method allows calculating efficiently the transforms of a signal having an arbitrary dimension of the digital representation by reducing the transform to a vector-to-circulant matrix multiplying.

Solyanik estimates in harmonic analysis

open access: yes, 2014
Let $\mathcal{B}$ denote a collection of open bounded sets in $\mathbb{R}^n$, and define the associated maximal operator $M_{\mathcal{B}}$ by $$ M_{\mathcal{B}}f(x) := \sup_{x \in R \in \mathcal{B}} \frac{1}{|R|}\int_R |f|.

Study on resonance characteristic of continuous co‐phase traction power supply system

open access: yesIET Generation, Transmission & Distribution, 2023
In order to solve the power quality problems and eliminate the neutral sections in the railway, the implementation of the continuous co‐phase traction power supply system (CCTPSS) is the development trend of the future. However, various parameters of the

Unbalance Response Analysis of a Rotor Kit with Two Identical Discs Located Between Bearings

open access: yesTehnički Glasnik, 2023
In this paper, the dynamic behavior of a rotor kit with two identical disks located between the plain bearings was analyzed. Modal and harmonic analysis of this rotor kit configuration were performed in the Ansys software package.

High-order harmonic generation at high laser intensities beyond the tunnel regime

open access: yes, 2014
We present studies of high-order harmonic generation (HHG) at laser intensities well above saturation. We use driving laser pulses which present a particular electron dynamics in the turn-on stage. Our results predict an increasing on the harmonic yield,
