Condition assessment of sewer pipelines using multi attribute utility theory (MAUT)
( International Society for Trenchless Technology , 2016 , Conference Paper)Many municipalities rely on the interpretation of Closed Circuit Television (CCTV) inspection reports to arrive to a condition assessment grade for the inspected sewer pipelines. The grades stand as a key for decision ... -
Condition prediction models for oil and gas pipelines using regression analysis
( American Society of Civil Engineers (ASCE) , 2014 , Article)Although they are the safest means of transporting oil and gas products, pipelines can sometimes fail with hazardous consequences and large business losses. The decision to replace, repair, or rehabilitate depends mainly ... -
Conditional dependence structure and risk spillovers between Bitcoin and fiat currencies
( Elsevier , 2023 , Article)This paper investigates the extreme dependence and risk spillovers between Bitcoin and the currencies of the BRICS and G7 economies. We find time-varying dependence between Bitcoin and all currencies. Moreover, when analysing ... -
