Abstract: Sediment transport in a turbulent channel flow over the sediment bed with a ripple structure is numerically simulated by means of a large eddy simulation. The filtered Navier-Stokes equations for the channel flow and the ...

Abstract: Failure of a public–private partnership (PPP) contract could cause heavy losses to sponsors. However, the current machine learning models neglect misclassification costs when predicting PPP contract failure. This research ...

Abstract: In this paper, submerged soil excavation by high-velocity water jet was investigated by means of a two-fluid smoothed-particle hydrodynamics (SPH) method. A critical state theory was coupled to account for the dilatancy ...

Abstract: Prefabricated concrete has substantial merits regarding a cleaner environment and less rework. However, precast concrete design suffers from an inefficient workflow. In this research, a new workflow is proposed by combining ...

Abstract: The public-private partnership (PPP) has been adopted by many governments in developing countries to provide better public services. However, PPP projects have a high risk of contract failure. To proactively predict PPP ...
