A Generalized Liaison Addition

open access: yesJournal of Algebra, 1994
If \(X\) and \(Y\) are curves in the projective three-space, \(M(X)\) and \(M(Y)\) their deficiency modules, and \(V\) a complete intersection of a surface containing \(X\) with a surface containing \(Y\), then in a natural way is defined a curve \(Z\) (which set-theoretically is \(X \cup Y \cup V)\) whose deficiency module is the direct sum of \(M(X)\)

Influence of surface roughness on the heat transfer coefficient of fluids in an additively manufactured supercharger

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022
The supercharger is intended for heating a fluid (gaseous helium or gaseous nitrogen) used for the pressurization of fuel tanks of oxidizer and propellant of a rocket engine. The fluid is heated with the generator gas downstream the turbine.

AN ALGORITHM TO CONSTRUCT VORONOI DIAGRAMS WITH OPTIMAL PLACEMENT OF GENERATOR POINTS BASED ON THE THEORY OF OPTIMAL SET PARTITIONING

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики", 2020
An algorithm is proposed for constructing a generalized Voronoi diagram with optimal placement of a finite number of generator points in a bounded set of n-dimensional Euclidean space.

An Algorithm for Finding Self-Orthogonal and Self-Dual Codes Over Gaussian and Eisenstein Integer Residue Rings Via Chinese Remainder Theorem

open access: yesIEEE Access, 2023
A code over Gaussian or Eisenstein integer residue ring is an additive group of vectors with entries in this integer residue ring which is closed under the action of constant multiplication by the Gaussian or Eisenstein integers. In this paper, we define

Functional Generalized Additive Models [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2014
We introduce the functional generalized additive model (FGAM), a novel regression model for association studies between a scalar response and a functional predictor. We model the link-transformed mean response as the integral with respect to t of F{X(t), t} where F(·,·) is an unknown regression function and X(t) is a functional covariate.

Z₂Z₄-additive cyclic codes, generator polynomials and dual codes

open access: yes, 2021
A Z₂Z₄-additive code C ⊆ Zα2 × Zβ₄ is called cyclic code if the set of coordinates can be partitioned into two subsets, the set of Z₂ and the set of Z₄ coordinates, such that any cyclic shift of the coordinates of both subsets leaves invariant the code ...

On Indistinguishability Operators, Fuzzy Metrics and Modular Metrics

open access: yesAxioms, 2017
The notion of indistinguishability operator was introduced by Trillas, E. in 1982, with the aim of fuzzifying the crisp notion of equivalence relation.

IDENTIFICATION OF MATHEMATICAL MODEL OF TURBINE GENERATOR UNIT IN PRESENCE OF UNCERTAINTY

open access: yesТехнічна електродинаміка, 2021
An identification procedure of mathematical model of turbine generator unit in the presence of uncertainty is studied for using in the interconnected robust control automated system. The procedure is based on “worst-case” identification approach.

Generalized Sparse Additive Models

open access: yesJournal of machine learning research : JMLR, 2019
We present a unified framework for estimation and analysis of generalized additive models in high dimensions. The framework defines a large class of penalized regression estimators, encompassing many existing methods. An efficient computational algorithm for this class is presented that easily scales to thousands of observations and features.
