Fuzzy Partial Metric Spaces and Fixed Point Theorems

open access: yesMathematics, 2022
Partial metrics constitute a generalization of classical metrics for which self-distance may not be zero. They were introduced by S.G. Matthews in 1994 in order to provide an adequate mathematical framework for the denotational semantics of programming ...

Eigenfunction Expansions for Second-Order Boundary Value Problems with Separated Boundary Conditions [PDF]

open access: yesMathematics Interdisciplinary Research, 2016
In this paper, we investigate some properties of eigenvalues and eigenfunctions of boundary value problems with separated boundary conditions. Also, we obtain formal series solutions for some partial differential equations associated with the second ...

Research on Tire Marking Point Completeness Evaluation Based on K-Means Clustering Image Segmentation

open access: yesSensors, 2020
The tire marking points of dynamic balance and uniformity play a crucial guiding role in tire installation. Incomplete marking points block the recognition of tire marking points, and then affect the installation of tires.

A Metric and Visualization of Completeness in Multi-Dimensional Data Sets of Sensor and Actuator Data Applied to a Condition Monitoring Use Case

open access: yesApplied Sciences, 2021
The so-called ‘Industrie 4.0’ provides high potential for data-driven methods in automated production systems. However, sensor and actuator data gathered during normal operation of the system is often limited to a narrow range of single, specific ...

Discontinuity at fixed point and metric completeness

open access: yesApplied General Topology, 2020
In this paper, we prove some new fixed point theorems for a generalized class of Meir-Keeler type mappings, which give some new solutions to the Rhoades open problem regarding the existence of contractive mappings that admit discontinuity at the fixed ...
