Solomon rings, upholding the symbol of wisdom with profound historical roots, were widely used as decorations in ancient architecture and clothing. However, it was only recently discovered that such topological structures can be formed by self-organization biological/chemical molecules, liquid crystals, etc. Here, we report observation polar rings a ferroelectric nanocrystal, which consist two intertwined vortices are mathematically equivalent to [Formula: see text] link topology. By...
In this article, the condition-based maintenance optimization of a K-out-of-N deteriorating system considering failure dependence is discussed. The degradation each component modelled by pure jump Lévy process. Whenever one fails, it can either induce instantaneous failures or lead to increment levels other components. Thus, model has flexibility describe phenomena multiple components, which known as common cause failure. It also accumulative, gradual propagation effect system. A periodic...
In the current era, green operation has become a key strategic direction for firm development, with its core being realization of win–win situation economic and environmental benefits through environmentally friendly production processes [...]
The advancement of event cameras has sparked a revolution in imaging technology, presenting exciting opportunities for vision-based measurement tasks. Event operate on an innovative asynchronous principle, which offers several advantages over traditional cameras, including ultra-high dynamic range and exceptional temporal resolution. As result, excel challenging environments characterized by motion blur, overexposure, or underexposure, outperforming conventional frame-based cameras. However,...
k-terminal network reliability is the probability that k terminal vertices are connected given edges in fail independently while do not fail. It depends on distribution of these as well topology. The problem computing NP-hard. Previous literature mainly focus designing efficient algorithms to compute it different graphs, but lacking analysis for optimal sparse within which those with n nodes and m edges, where ≤ + 1, most basic classes. Hence, great significance investigate classes graphs...
With the help of advanced digital technologies, product managers can use monitored mission cycles to sustain reliability. In this study, a random warranty model and replacement next (RRN) are designed through-life reliability with cycles. The warranty, called two-stage two-dimensional free repair (2DFRW), be carried out during stage. ‘whichever occurs first last’ is used distinguish coverage ranges latter stage warranties, which maintain fairness by removing inequity former warranty. RRN...
In order to understand the two-way coordination of mine water supply and demand in Ningdong coal base, contradiction between this area will be solved some extent. Based on theory resources balance analysis, paper establishes a coordinated evaluation index system for based survey data. The analytic hierarchy process entropy method are used determine weight index. TOPSIS is evaluate base Yinchuan, Shizuishan, Lingwu Wuzhong. Regional coordination. results show that under current mining mode,...
The Chronic Kidney Disease Management Centre (CKDMC) primarily focuses on developing a new system for early screening, standardised diagnosis, treatment, and the long-term follow-up management of patients with chronic kidney disease (CKD) to enhance CKD prevention management. Nurses play pivotal role in comprehensive CKD, contributing considerably improvement patient survival. Consequently, this study constructs an evaluation index nursing positions CKDMC, delineating required competencies...

The water-soluble mining is often accompanied by ground subsidence, which could result in the severity of subsidence disasters. roof salt-bearing strata Longgui salt rock area close to third aquifer, mostly composed muddy conglomerate and other porous rocks with large porosity permeability. for many years has caused serious area, there a tendency accelerate subsidence. Taking mine as case, mechanism was analyzed discussed through water dissolution simulation test. This study great...
In this paper, the reliability and maintenance modelling of a system with dependent main auxiliary components is considered. The consists one degrading component that takes charge functionality several protective components. Failure dependence exists among components:within components, whenever fails, it may induce increment failure rate survival Meanwhile, can accumulative damages to component.The periodically inspected, upon which, degradation level state each are observed. Considering...
The reliability of supply chain network system design and optimization based on the industrial cluster was discussed, that is, operational platform multi-objective moved to cluster, so has effects both regional radiation scale economy. Instead some static research methods such as former traditional mathematic planning, systematic dynamic analysis, this paper put forward a coordinative mechenism construction, used simulation method which combined with weighing in region, should be cost...
