Pseudosymmetric Spaces as Generalization of Symmetric spaces [PDF]
In this paper, the concept of a pseudosymmetric space which is a natural generalization of the concept of a symmetric space is defined. All basic concepts such as the Luxemburg representation theorem, the Boyd indices, the fundamental function and its ...

$L_{p;r} $ spaces: Cauchy Singular Integral, Hardy Classes and Riemann-Hilbert Problem in this Framework [PDF]
In the present work the space $L_{p;r} $ which is continuously embedded into $L_{p} $ is introduced. The corresponding Hardy spaces of analytic functions are defined as well. Some properties of the functions from these spaces are studied.

A High Power Quality Buck-H Auxiliary Power Converter in Railway Applications
DC voltage utilization and AC voltage harmonics are important evaluation indexes for Auxiliary Power Converter in Railway Applications. To improve the above two indicators, a novel switch-mode modulation method and quasi-PR control strategy for Buck-H ...

Harmonic Voltage Synchronization Using GPS Modules for Grid-Connected Power Converters
Voltage-controlled inverters (VCI) for distributed energy resources allow operation in grid-connected and islanded conditions. Common techniques based on $P$-$f$, $Q$-$V$ droop-control use sinusoidal voltage references for the VCIs, which brings unwanted

A unified representation of some starlike and convex harmonic functions with negative coefficients [PDF]
In this paper we introduce a unified representation of starlike and convex harmonic functions with negative coefficients, related to uniformly starlike and uniformly convex analytic functions.

On bases from cosines in Lebesgue spaces with variable summability index
In this paper the perturbed system of cosines is considered. Under certain conditions on the summability index p ( ⋅ ) $p (\cdot )$ and perturbation, the basicity of this system in Lebesgue spaces L p ( ⋅ ) ( 0 , π ) $L_{p (\cdot )} (0,\pi )$ with ...

There are several ways to reduce the ripple magnitude for direct torque-controlled permanent magnet synchronous motor (PMSM) drives. In this work, the compensated duty ratio optimized direct torque control (DDTC-TC) method was proposed to reduce the ...
