Abstract: We statistically analyze the actual ship motion steered by the AR autopilot system developed by the authors in 1977. The analysis is based on a multivariate AR modeling of time series observed ...

Abstract: In the past two decades, accidental failure of conical-shaped steel water tanks under hydrostatic pressure has been reported. For safety analysis, the limit analysis of such structures is formulated as a linear programming ...

Abstract: The transition from supercritical to subcritical flow in sloping channels is systematically investigated under a wide range of slopes. The hydraulic conditions for the formation of D‐jump, where the entire jump is formed ...

Abstract: Supercritical flow below a sluice gate in a horizontal smooth rectangular channel is investigated to explain the effect of the inflow condition on the characteristics of the hydraulic jump. The movement of jump location ...

Abstract: This paper presents an experimental observation of the relation between the plastic damage and the acoustic emission (AE) events in concrete subjected to uniaxial compressive loading. To examine the effect of the degree ...

Abstract: In submerged flows below an expanding outlet, both symmetric and asymmetric flows are observed. The hydraulic conditions required to form a symmetric submerged jump are necessary for design purposes. In this study, the ...

Abstract: The flow conditions of undular jumps for fully developed inflow condition have been investigated systematically. If the inflow Froude number is larger than 1.2, an undular jump has lateral shock waves near the toe of the ...
