‎Intuitionistic Fuzzy Modular Spaces [PDF]

open access: yesTransactions on Fuzzy Sets and Systems, 2023
‎After the introduction of the concept of fuzzy sets‎ ‎by Zadeh‎, ‎several researches were conducted on‎ ‎the generalizations of the notion of fuzzy sets‎. ‎There are many viewpoints on the notion of metric space in fuzzy topology‎.

On Fuzzy Modular Spaces [PDF]

open access: yesJournal of Applied Mathematics, 2013
The concept of fuzzy modular space is first proposed in this paper. Afterwards, a Hausdorff topology induced by a β-homogeneous fuzzy modular is defined and some related topological properties are also examined.

Fixed Point Results on Partial Modular Metric Space

open access: yesAxioms, 2022
In the present paper, we refine the notion of the partial modular metric defined by Hosseinzadeh and Parvaneh to eliminate the occurrence of discrepancies in the non-zero self-distance and triangular inequality. In support of this, we discuss non-trivial

Modular Line-Focused Space Solar Power Satellite

open access: yesAerospace, 2021
The Space Solar Power Satellite is an ultra-large space structure, which collects sunlight directly in space and then transmits it into the ground. Since the idea was invented in 1968, scientists around the world have proposed several typical conceptual ...

Design and Dynamic Simulation Verification of an On-Orbit Operation-Based Modular Space Robot

open access: yesApplied Sciences, 2023
Space robots have been playing an important role in space on-orbit operation missions. However, the traditional configuration of space robots only has a single function and cannot meet the requirements of different space missions, and the launch cost of ...

Emergence of kinematic space from quantum modular geometric tensor

open access: yesPhysics Letters B, 2022
We generalize the Quantum Geometric Tensor by replacing a Hamiltonian with a modular Hamiltonian. The symmetric part of the Quantum Geometric Tensor provides a Fubini-Study metric, and its anti-symmetric sector gives a Berry curvature. Our generalization

A Passive Vibration Control Method of Modular Space Structures Based on Band Gap Optimization

open access: yesInternational Journal of Aerospace Engineering, 2022
Modular space structure has become a research hotspot in the aerospace field. In the microgravity and weak damping space environment, modular space structures may continuously vibrate due to the transient excitation caused by satellite attitude ...
