Abstract: After many years of service, constructed infrastructure facilities including drainage pipes, bridges, and roads show sign of deterioration. To ensure public safety and efficient management of these crucial assets, condition ...

Abstract: This study aims to assess the reliability of hydraulic performance of concrete pipes at the design stage. The reliability assessment is on the basis of the use of Markov chain theory for modeling pipe deterioration during ...

Abstract: Air valves are normally installed at high points along undulating pipelines to allow for air discharge or intake during filling or dewatering. Initial filling of a newly constructed pipeline, or refilling a portion of an ...

Abstract: A homogeneous model for prediction of the longitudinal distributions of pressure, velocity, and void fraction for two-phase bubbly flow in horizontal pipes is presented. The mixture flow is ...

Abstract: In this note we present some results on stochastic dynamics with respect to a fractional Brownian motion from a L2approximation approach. A new and simple definition of fractional stochastic integral is introduced and a ...

Abstract: The propagation of pressure waves in two-component bubbly flow was analytically and experimentally investigated. An analysis is presented that accounts for the effects attributable to liquid compressibility, pipe elasticity, ...

Abstract: Check valves are normally installed at pumping stations to prevent reverse flow through pumps after pump shutdown. Check-valve slam appears to be among the most common causes of water hammer in water supply systems. A ...

Abstract: Progressive design-build (PDB) has been successfully administered and executed in the private, airport, transit, and water/wastewater sectors. Although these sectors have experienced successes with PDB, there is limited ...

Abstract: The typical challenge encountered in developing heavy-oil reservoirs is inefficient wellbore lifting caused by complex multiphase flows. The literature on modeling of a hybrid artificial-lift (AL) system is relatively ...

Abstract: In this paper, for the first time, isogeometric analysis (IGA) and nonlocal theory are used to investigate the free vibration and transient response of bidirectional functionally graded porous (BFGP) curved nanobeams with ...
