Purpose This study aims to optimize the design of falling film heat exchangers by providing a deeper understanding wave characteristics and capillary flow in laminar inclined films at low Reynolds numbers. The focus is on effects different Kapitza numbers, influenced fluid properties inclination, interfacial behavior. Design/methodology/approach A numerical investigation was conducted using volume method within OpenFOAM’s interFoam solver. examined number, inclination angle inlet...

Online multiplayer games are supposed to match single players or squads with similar abilities. They depend on different kinds of rating systems ensure a fair and competitive gaming environment. Traditional generally focus evaluation criteria, such as Elo scores number killings. However, like Overwatch, which have more aspects, the usage items skills corporation whole team, need some complex systems. Because these, those traditional cannot satisfy needs modern online games. Thus, it is...

It is essential to study the allocation of carbon emission quotas key high-carbon industries. Here, we used theoretical generation performance standard (GPS) evaluate inputs and outputs five major Chinese power groups. We predicted their 2017, 2020, 2030 performances using a grey prediction model based on 2011–2016 data, then applied GPS calculate target year distributions emissions, finally employing data envelopment analysis (DEA) effectiveness these allocations. The trading evaluations...

How does environmental regulation affect ecological efficiency? What is the role of industrial transfer in mechanism action? Relations and interactions between three determine economic quality when performance concerned. Empirical studies this paper are based on samples from Yangtze River belt China, which contributes nearly half China’s GDP. By measuring regulation, transfer, efficiency, data indexes prepared for investigating driving illustrating transfer. applying Markov process to model...

This paper deals with optimal prediction in a regime-switching model driven by continuous-time Markov chain. We extend existing results for geometric Brownian motion deriving stopping strategies that depend on the current regime state and prove number of continuity properties relating to value boundary functions. Our approach replaces use closed form expressions, which are not available our setting, PDE arguments also simplify [du Toit & Peskir (2009) Selling stock at ultimate maximum,...

Artificial Intelligence (AI), particularly through the advent of large-scale generative AI (GenAI) models such as Large Language Models (LLMs), has become a transformative element in contemporary technology. While these have unlocked new possibilities, they simultaneously present significant challenges, concerns over data privacy and propensity to generate misleading or fabricated content. Current frameworks for Responsible (RAI) often fall short providing granular guidance necessary...

Abstract At present, information technology has been widely used in various fields, which also led to the modernization of logistics management China. The new generation penetrated into different professional such as mechanical engineering, electronic communication image processing and so on. Through technology, enterprise moving towards road automation intelligence, is development trend modern enterprises. same time, promotes application management, will help enterprises move process...

A novel semi-blind channel estimation is devised to jointly estimate the matrices of all links in a three-hop multiple-input multiple-output (MIMO) relay system. By exploiting KRST coding structure source node, PARAFAC tensor model firstly investigated process estimating compound matrix consisting state information links. Then, through designed amplification at nodes, PARATUCK-2 based algorithm further extract sub-channel matrices. The proposed uses two-stage iterative fitting for joint...

INTRODUCTION: Accurate and objective human resources performance management evaluation methods are conducive to a comprehensive understanding of the real situation teachers, identifying management, teaching academic level which enables teacher managers have clear gaps problems among teachers. OBJECTIVES: Aiming at current method, there indexes exist objectivity is not strong, poor precision, single method other problems. METHODS: This research puts forward an intelligent optimisation...

Abstract Using panel data from 2012 to 2018, this article investigates the long‐term impact of household debt on consumption, which is very important sustainable development economy. The result shows that total has a significant crowding‐out whereas nonhousing no effect it. In addition, we also find high‐asset families weaker consumption; rural families, however, greater effect, means increasing families' leverage will have negative consumption. Finally, debt's consumption was not found in...

In the real world, as complexity of optimization problems continues to increase, there is an urgent need research more efficient methods. Current algorithms excel in solving with a fixed number dimensions. However, their efficiency searching dynamic multi-dimensional spaces unsatisfactory. response challenge cross-dimensional search varying numbers dimensions, this study proposes new algorithm-Dynamic Dimension Wrapping (DDW) algorithm. Firstly, by utilizing Dynamic Time Warping (DTW)...
