Proceedings ArticleDOI
A route planning for disaster waste disposal based on robot technology
TL;DR: A transportation management system for disaster wastes to support early recovery from great the effect of earthquakes and other natural disasters is described and is able to manage waste transportation by using a map that simulated south Tokyo.
Journal ArticleDOI
Study on failure rate analysis for water distribution pipelines
TL;DR: In this article, the authors apply reliability engineering in the waterworks field as one possible approach and to show its viability; it will also obtain vital messages revealed within pipeline incident data, such as cumulative failure distribution (unreliability) by pipeline material, the failure probability density and failure rate, among others.
Journal ArticleDOI
Optimized operation of water distribution system using multipurpose fuzzy LP model
TL;DR: In this paper, a multi-objective optimization of water operations in a water supply and distribution system is proposed to reduce energy consumption while meeting water quality needs, where fuzzy linear programming (LP) is applied to achieve a balance among multiple objectives.
Journal ArticleDOI
Water leak detection based on convolutional neural network using actual leak sounds and the hold-out method
TL;DR: A method for detecting water leaks was developed using a convolutional neural network, after taking recurrence plots and visualising the time series as input data, and tested using the hold-out method.
Journal ArticleDOI
Optimization model for water distribution network considering minimization of total replacement cost and stabilization of flow velocity in pipelines
TL;DR: In this article, a method using genetic algorithms (GA) to optimize selection of appropriate pipe diameter during pipeline replacement planning for water distribution networks was proposed. But this method does not consider the stability of flow velocity in pipes.
