Abstract The importance of the effective distribution runoff in sewer network throughout a detention facility has recently been recognized. This study aims to determine location and capacity facilities urban network. optimal can be determined by numerous iterations an optimization model. In this paper, interfacing Visual Basic (VB) programming tool with SWMM (Storm Water Management Model) DLL for hydraulic hydrological computation completes routine. A multi-objective genetic algorithm (MOGA)...

In this study, we provide a comparative analysis of intangible cultural heritage (ICH) research trends in Korea and Japan, aiming to uncover shared knowledge networks potential areas for sustainable cooperation. We employ mixed-method approach, combining machine learning-driven topic modeling using Latent Dirichlet Allocation (LDA) network techniques, examine corpus Korean Japanese papers on ICH. LDA identified three primary themes: technology ICH, safeguarding methodologies approaches ICH...

In recent years, significant changes have been taking place in manufacturing industries. To cope with the and intense competitions, most industries made remarkable effort by implementing CIM systems, but they not successful such efforts, which can be summarized into three major reasons. The first reason is conceptual misunderstanding of its optimizations. second lies excluding human factors to build CIM. third division technologies organizations. This article represents a human-centered...

The microbial communities of 5-stage BNR activated sludge samples were analyzed using fluorescence in-situ hybridization (FISH) and 16S rDNA characterization. total cell numbers each reactor from 2.36 × 109 cells/ml to 2.83 cells/ml. From 56.5% 62.0% DAPI counts hybridized the most bacterial specific probe EUB 338. Among them, b-proteobacteria dominant in tank. number phosphate accumulating organisms (PAOs) was almost 50% anoxic-1 tank, these results indicate that this process has a high...

In this study a demand forecasting Optimal Life-cycle Energy Design (OLED) model is developed. The enables the determination of life-cycle existing Water Distribution Systems (WDSs) as well optimal design new WDSs. Harmony Search used optimization algorithm with objective function minimizing energy expenditure per year. A WDS analysis program EPANET 2.0 linked for solving hydraulic constraints. Demand also possible in to consider changes future. Results show that designing developed can...
