Investigation of the Wear Resistance of a Journal Bearing with Polymer-Coated Grooved Support Ring
Advanced Engineering Research, 2023 Introduction. In modern heavy-loaded friction units, metallopolymer coated bearings operating in the boundary friction mode are widely used. Their successful application is provided by the viscoelastic deformation of these coatings under load.

Ultralogics and probability models
International Journal of Mathematics and Mathematical Sciences, 2001 We show how nonstandard consequence operators, ultralogics, can generate the general informational content displayed by probability models. In particular, a probability model that predicts that a specific single event will occur and those models that ...

SNSequate: Standard and Nonstandard Statistical Models and Methods for Test Equating
Journal of Statistical Software, 2014 Equating is a family of statistical models and methods that are used to adjust scores on two or more versions of a test, so that the scores from different tests may be used interchangeably.

Crossover dynamics of climate change models: Numerical simulations
Alexandria Engineering Journal, 2023 In this paper, two new climate change mathematical models are extended using the stochastic-deterministic piecewise hybrid fractional derivatives, where the hybrid fractional order operator is applied to extend the deterministic model and the fractional ...

Nonstandard Higgs decays in the E6 inspired SUSY models [PDF]
, 2016 We consider the exotic decays of the SM-like Higgs state within the E6 inspired supersymmetric (SUSY) models. In these models the lightest SUSY particle (LSP) can be substantially lighter than 1 eV forming hot dark matter in the Universe.

Advanced Engineering Materials, EarlyView.Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Non-standard discretization of biological models [PDF]
, 2015 We consider certain types of discretization schemes for differential equations with quadratic nonlinearities, which were introduced by Kahan, and considered in a broader setting by Mickens.
