The Use of Kramers-Kronig Relations for Verification of Quality of Ferrite Magnetic Spectra
The complex initial permeability (CIP) as a function of frequency is one of the main properties of ferrites. This characteristic (CIP) is measured experimentally, therefore there can be found noisy, doubtful or incomplete parts of the spectrum.

The Place of Quasi Topological Structure in the Mathematical Theory of Categorization
This work is a theoretical one bridging two mathemat- ical models namely the Quasi Topological Structure (QTS) and Soft Sets (SST) theories. We prove that theQuasi Topological Structure (QTS) can be viewed as a complexification of Soft Sets, from the ...

Divergence of high order Gaussian modes [PDF]
A simple expression for the beam divergence from a laser oscillating in a high order Gaussian mode can be derived from the properties of the mathematical expressions for these ...

Mathematical simulation of catalytic paste flow in a ram extruder [PDF]
A mathematical model was developed for the stage of catalyst paste preparation. The mathematical model allows the calculation of solvate film thickness and volume content of the solid phase at any moment of time. Functional dependencies were found, which

Mathematical properties of ordered amplitude graphs [PDF]
Abstract This paper elaborates on some mathematical aspects of the ordered hadronic amplitudes. In particular, a systematic way of constructing the ordered Hilbert space is presented and it is shown to be the most general Hilbert space consistent with unitarity of the S -matrix.

Dynamical Casimir effect in a periodically changing domain: A dynamical systems approach [PDF]
We study the problem of the behavior of a quantum massless scalar field in the space between two parallel infinite perfectly conducting plates, one of them stationary, the other moving periodically.

Pseudospectra in non-Hermitian quantum mechanics [PDF]
We propose giving the mathematical concept of the pseudospectrum a central role in quantum mechanics with non-Hermitian operators. We relate pseudospectral properties to quasi-Hermiticity, similarity to self-adjoint operators, and basis properties of ...

Weakly-entangled states are dense and robust
Motivated by the mathematical definition of entanglement we undertake a rigorous analysis of the separability and non-distillability properties in the neighborhood of those three-qubit mixed states which are entangled and completely bi-separable.
