Abstract: Transient response of an interfacial crack between two dissimilar elastic, orthotropic solids is investigated. The interfacial crack is excited by tractions suddenly applied on the crack surfaces. ...

Abstract: Dynamic stress intensity factors for an interfacial crack between two dissimilar elastic, fully anisotropic media are studied. The mathematical problem is reduced to three coupled singular integral ...

Abstract: To study the effects of the high elongational viscosity on the free (“grid-generated”) turbulence of polymer solutions, a Burgers-type model equation is proposed and formed by replacing the ...

Abstract: The current control systems adopted by most industrial manipulators are “open loop” designs based only upon kinematic consideration. Their servo gains are fixed and there is no flexibility of ...

Abstract: An inverse model of an estuarine eutrophication model with eight state variables is developed. It provides a framework to estimate parameter values of the eutrophication model by assimilation of concentration data of these ...

Abstract: A procedure to calibrate an estuarine eutrophication model of the tidal Rappahannock River, a western tributary of the Chesapeake Bay, Va., using an inverse model is described. The inverse model using variational technique ...

Abstract: An estuarine frontal system was investigated with a series of numerical experiments using a 3D hydrodynamic model. The model results were confirmed with field observations and compared with theoretical analysis. Various ...

Abstract: The success of a robot force and position (hybrid) control scheme relies extensively upon its robustness against uncertainties such as unknown external disturbance or modeling errors in the ...

Abstract: We consider a control design problem for a class of uncertain systems. The salient features of the problem are fourfold. First, the uncertainty is time-varying. Second, the system is nonlinear. ...
