An estimation of the stability and the localisability functions of multistable processes [PDF]

open access: yes, 2012
Multistable processes are tangent at each point to a stable process, but where the index of stability and the index of localisability varies along the path.

Evaluation of corrosion and scaling potential of drinking water supply sources of Marivan villages, Iran [PDF]

open access: yesJournal of Advances in Environmental Health Research, 2015
Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study
