Weak enforcement of interface continuity and generalized periodicity in high‐order electromechanical problems [PDF]

International Journal for Numerical Methods in Engineering, 2021
AbstractWe present a formulation for the weak enforcement of continuity conditions at material interfaces in high‐order problems by means of Nitsche's method, which is particularly suited for unfitted discretizations. This formulation is extended to impose generalized periodicity conditions at the unit cell boundaries of periodic structures.

Prevalence and associated factors of fear of childbirth among pregnant women in Saudi Arabia [PDF]

Frontiers in Psychiatry
BackgroundFear of childbirth (FOC) is a common concern among pregnant women and can significantly impact maternal and fetal well-being. This study estimates the prevalence of childbirth fear, its determinants and correlation with depression and anxiety ...

Some Classes of Soft Functions Defined by Soft Open Sets Modulo Soft Sets of the First Category

Mathematics, 2023
Soft continuity can contribute to the development of digital images and computational topological applications other than the field of soft topology. In this work, we study a new class of generalized soft continuous functions defined on the class of soft

The Equivalence of Convergence Results between Mann and Multistep Iterations with Errors for Uniformly Continuous Generalized Weak Φ‐Pseudocontractive Mappings in Banach Spaces [PDF]

Abstract and Applied Analysis, 2012
We prove the equivalence of the convergence of the Mann and multistep iterations with errors for uniformly continuous generalized weak Φ‐pseduocontractive mappings in Banach spaces. We also obtain the convergence results of Mann and multistep iterations with errors. Our results extend and improve the corresponding results.

Q-Learning for MDPs with General Spaces: Convergence and Near Optimality via Quantization under Weak Continuity

, 2021
Reinforcement learning algorithms often require finiteness of state and action spaces in Markov decision processes (MDPs) (also called controlled Markov chains) and various efforts have been made in the literature towards the applicability of such algorithms for continuous state and action spaces.

Fast Implementation of Insect Multi-Target Detection Based on Multimodal Optimization

Remote Sensing, 2021
Entomological radars are important for scientific research of insect migration and early warning of migratory pests. However, insects are hard to detect because of their tiny size and highly maneuvering trajectory.

Fixed Point Results under Generalized c-Distance in Cone b-Metric Spaces Over Banach Algebras

Axioms, 2020
In this work, we define the concept of a generalized c-distance in cone b-metric spaces over a Banach algebra and introduce some its properties. Then, we prove the existence and uniqueness of fixed points for mappings satisfying weak contractive ...
