The current situation and future development of the supply demand coupling coordination elderly care service resources reflect level resource allocation. Whether factors affecting its can be found is key to promote accurate allocation service. Based on model, resources, circumstance spatio-temporal evolution are analyzed in this paper by using data 31 regions autonomous China from 2010 2019. result shows that there regional differences resources. degree western northern lower than eastern...

By utilising the two-dimensional phase field model with phenomenological anti-trapping current, morphological pattern formation of particles within alloy melt during initial crystal growth is studied. The results numerical simulations elucidate that two progressively converge and interact, ultimately coalescing into a microstructure, subsequently, microstructure interface undergoes deformation growth. To be specific, differential orientation across various parts prompts concentration...

This paper focused on three application problems of the traditional Deep Deterministic Policy Gradient(DDPG) algorithm.That is, agent exploration is insufficient, neural network performance unsatisfied, output fluctuates greatly.In terms strategy, training algorithm and overall implementation, an improved DDPG method based double-layer BP proposed.This introduces fuzzy BFGS Armijo-Goldstein criterion, improves efficiency, learning efficiency convergence network, increases number layers to...

With the rapid growth of elderly population China in recent years, service demands older Chinese people continue to increase. The increasingly severe situation with respect is an important social problem that will face for a long time into future. It urgent solve how scientifically carry out allocation planning resources aged and guide effective supply resources. This paper analyzes factors affecting aged, divides China’s resource demand system subsystem, economy subsystem. Using dynamics...

(1) Objective: to accelerate the digitalization of elderly care service industry and construction smart industry, this paper designs an intelligent e-procurement system for suppliers selecting from perspective care, which can enhance efficiency supply chains assist manufacturers products in choosing a reliable, high-quality supplier during trades. (2) Methods: system, including six modules, is built with improved dynamic Markov Decision Process selection model combined Analytic Network...

In this paper, focusing on the inconvenience of variable value PID based manual parameter adjustment for hydraulic drive unit (HDU) a legged robot, method employing double-layer back propagation (BP) neural networks learning law control parameters is proposed. The first layer used to learn relationship between different and performance system under various working conditions. second study conditions optimizing effectiveness proposed was verified by simulation experiment. results showed that...

Recent studies in big data analytics and natural language processing develop automatic techniques analyzing sentiment the social media information. In addition, growing user base of high volume posts also provide valuable information to predict price fluctuation cryptocurrency. This research is directed predicting volatile movement cryptocurrency by finding correlation between them. While previous work has been developed analyze English posts, we propose a method identify Chinese from most...

Consumer behaviors have always been the hot spot of study. With arrival network age and popularity e-commerce, consumption pattern shopping online is beginning. Until December 2014, there were 649 million Internet users in China, it's increasing. In year number most mainstream shoppers has increased by 23.7% become an irresistible trend. New mode can produce a new research subject, study consumer becomes very important. This article used LocoySpider, data mining software, to mine Taobao...

Accountability in the workplace is critically important and remains a challenging problem, especially with respect to safety management. In this paper, we introduce novel notion, Internet of Responsibilities, for accountability Our method sorts through list responsibilities hazardous positions. The positions are interconnected using directed acyclic graphs (DAGs) indicating hierarchy organization. addition, system detects collects responsibilities, represents risk areas terms responsibility...

Supply chain coordination has been a research hot spot in supply management. This paper constructs secondary system. Taking the abatement of bullwhip effect and double marginal as objective, simulation study decision was conducted using system dynamics. First, by controlling lead time, it found that decentralized decision-making model, profit supplier whole increases with shortening vice versa for retailer. In centralized model addition information sharing contract, retailer’s is consistent...

ABSTRACT This study investigated the effects of 8,12‐dimethoxysanguinarine (DSG) from Eomecon chionantha Hance on malignant biological activity breast cancer cells. RNA‐sequencing measure analysis revealed that metastasis‐related genes were significantly downregulated in DSG‐treated MCF‐7 DSG inhibits migration ability Molecular docking studies demonstrated significant interactions between and Fibronectin 1 (FN1) protein, with a binding energy ‐8.91 kcal/mol. Additionally, FN1 messenger RNA...

With the large-scale wind farm in Grid, stability of power system is becoming hot issue. But forecasting methods and development not enough perfect. So paper proposed architecture Forecasting System for Wind Farm Power, expounded function every module system. It designed class diagram Power based on BP. In end, application JAVA. The result showed that model JAVA technology feasibility effectiveness.

We consider the Cox–Ingersoll–Ross (CIR) model in time-dependent domains, that is, CIR process domains reflected at boundary. This is a very meaningful question, as commonly used to describe interest rate models, and rates are often artificially set within domain by policy makers. most fundamental question of recurrence versus transience for normally with we examine some precise conditions terms growth The drift diffusion processes carefully provided. In case, also investigate last passage...

The two-dimensional thermodynamically consistent phase field model, which consists of the anisotropic Allen-Cahn type equation and heat equation, is used to study morphological pattern particle in initial stage crystal growth. results reveal locally reversible growth Specifically, some parts interface first grow inward, while others outward from critical nucleation, until speed becomes zero. After this, inward start with other parts. leads development a petal-like shape. radius size...

The developed division and specialization exists in the industrial cluster between enterprises. transactions of intermediate products upstream downstream enterprises same product are so frequent that competitiveness final consumer market depends on cooperation Therefore, labor is basic force development division. increased transaction costs, resulted from increasing amount trades, request efficient organization developing process produce, to reduce costs various kinds trading activities. As...
