Abstract: A class of problems that has received considerable attention in recent years from both control theorists and engineers is the following: Given ẋ = Fx + du, x(0) = cDetermine |u(t)| ≤ 1 ...

Abstract: In this paper, we study the control of the dynamic system governed by the matrix differential equation, ẋ = Fx + Du , x (0) = −c , where the input vector u is constrained in amplitude. ...

Abstract: Acoustic metasurfaces use the phase gradient of a single layer to reflect/refract waves in any direction. This study shows that other than wave steering, acoustic metasurfaces can exhibit wave splitting or trapping through ...

Abstract: A rigid sphere approaching a lubricated flat surface with a layer of elastic coating on the elastic substrate is explored under constant load conditions. The transient pressure profiles, film shapes, elastic deformation, ...

Abstract: The vortex lock-in in the laminar wake behind a circular cylinder induced by the unsteady monopole source is numerically simulated in this paper. The artificial compressibility method is employed ...

Abstract: Flow duration curves (FDCs) are useful tools for many water resource development and management purposes. Many water resource projects are located at ungauged sites, however, for which FDCs are required but unavailable due ...

Abstract: A new precast segmental bridge pier system using modular construction methodology is proposed in this study. The proposed system contains multiple segmental layers with several small precast modular RC segments for each ...

Abstract: Calibration is a necessary process for rainfall-runoff models. A fuzzy multiobjective function (FMOF) was proposed to combine various objective functions using only three important features of a hydrograph (i.e., time to ...

Abstract: A hole-effect autocorrelation function is one that is non-monotonic or pseudo-periodic as defined in the geostatistics literature. This paper shows that such an autocorrelation function (ACF) can influence the probability ...
