Teleparallel Minkowski Spacetime with Perturbative Approach for Teleparallel Gravity on a Proper Frame

open access: yesUniverse, 2023
A complete perturbation theory suitable for teleparallel gravity is developed. The proposed perturbation scheme takes into account perturbations of the coframe, the metric, and the spin-connection, while ensuring that the resulting perturbed system ...

Reliability Analysis of a Load-Sharing k-out-of-n System Due to Its Components’ Failure

open access: yesMathematics, 2022
The reliability characteristics of a k-out-of-n:F system are studied in the case when a failure of one of the system’s components leads to increasing the load on others, resulting in their residual lifetimes decreasing.

Channel Identification Based on Cumulants, Binary Measurements, and Kernels

open access: yesSystems, 2021
In this paper, we discuss the problem of channel identification by using eight algorithms. The first three algorithms are based on higher-order cumulants, the next three algorithms are based on binary output measurement, and the last two algorithms are ...

Two-Center Basis Generator Method Calculations for Li3+, C3+ and O3+ Ion Impact on Ground State Hydrogen

open access: yesAtoms, 2022
The two-center basis generator method is used to obtain cross sections for excitation, capture, and ionization in Li3+, C3+, and O3+ collisions with ground-state hydrogen at projectile energies from 1 to 100 keV/u.

Situations, alternatives, and the semantics of ‘cases’ [PDF]

open access: yesLinguistics and Philosophy, 2019
AbstractThis paper argues that NPs withcaseas head noun stand for situations in their role as truthmakers within a sentential or epistemic case space. The paper develops a unified semantic analysis ofcase-constructions of the various sorts within a truthmaker-based version of alternative semantics.

Banach Fixed Point Theorem in Extended bv(s)-Metric Spaces

open access: yesComputer Sciences & Mathematics Forum, 2023
We define the class of extended bv(s)-metric spaces by replacing the real number s≥1 with a strictly increasing continuous function ϕ in the definition of a bv(s)-metric space.

A Recipe for State-and-Effect Triangles [PDF]

open access: yesLogical Methods in Computer Science, 2017
In the semantics of programming languages one can view programs as state transformers, or as predicate transformers. Recently the author has introduced state-and-effect triangles which capture this situation categorically, involving an adjunction between

Data Mining Meets Logic: Situation-Based Modal Logic and Metadata Veracity

open access: yesScience & Philosophy
Logic and theoretical computer science are deeply interconnected, with logic forming a foundational pillar in the emergence of computer science. This connection has grown stronger over time, driven by advancements in symbolic systems within artificial ...
