Impact of Commutation Failure Preventions on HVDC System Based on a Multi-Index Value Set Approach

open access: yesIEEE Access, 2021
This paper proposes a systematic method, based on rational approximation and value set approach, to unravel the impact of commutation failure preventions (CFPREVs) on HVDC system dynamics.

Substantiation of rational parameters of open-pit development of a two-layer deposit [PDF]

open access: yesE3S Web of Conferences, 2023
Technological schemes for open pit mining of mineral deposits show the reduce of costs by diminishing the distance of transportation. The development of fundamentally new types of technological schemes includes the division of the mining front into ...

Development of a comprehensive approach to determining the rational parameters of an onboard capacitive energy accumulator for a subway train

open access: yesEastern-European Journal of Enterprise Technologies, 2019
One of the essential, yet insufficiently studied, issues related to the implementation of onboard capacitive energy accumulators in the subway is determining their rational parameters (power and energy intensity).

Erratum to: The generalized strong recurrence for non-zero rational parameters [PDF]

open access: yes, 2010
In the present paper, we prove that self-approximation of $${\log \zeta (s)}$$ with d = 0 is equivalent to the Riemann Hypothesis. Next, we show self-approximation of $${\log \zeta (s)}$$ with respect to all nonzero real numbers d. Moreover, we partially

C2-rational cubic spline involving tension parameters

open access: yesProceedings Mathematical Sciences, 2000
Shape preserving interpolation with rational (cubic/linear) splines is considered. The splines are parametrised with two (tension) parameters and are Hermite interpolants matching function values and derivatives in the knots. The main results are theorems about the following topics. An upper bound for the approximation error.

Arranging parameters of self-anchored stressed ribbon supported on arch pedestrian bridges / Vienajuosčių kabamųjų paremtų arka pėsčiųjų tiltų pusiausvirosios sistemos komponavimas

open access: yesMokslas: Lietuvos Ateitis, 2017
Stressed ribbon pedestrian bridges are most graceful, efficient and economical strains of suspension bridges. However, these structures have a major disadvantage – very large horizontal support reactions, which result mainly to the construction cost.

Equilibrium measures in the presence of certain rational external fields [PDF]

open access: yes, 2015
Equilibrium measures in the real axis in the presence of rational external fields are considered. These external fields are called rational since their derivatives are rational functions.
