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 constitutive relations of the thermoviscoelasticity are rigorously formulated, and the corresponding finite-element equations are derived. Due to the second law of thermodynamics, a nonlinear term, which appears in ...

Abstract: Project delays due to late availabilities of resource and information (RI) prerequisites are one of the major threats to construction management. It is desirable to avoid such delays through better means of constraint ...

Abstract: In the GE 7FDL single-cylinder research diesel engine, coal-water slurry (CWS) fuel combustion optimization studies were conducted using electronically controlled CWS and pilot accumulator injectors. ...

Abstract: In order to predict the fatigue crack growth curve under random loading, an analytical model is proposed in this paper. In addition to the mean crack growth curve, the model also considers ...

Abstract: A formulation specifying the bottom shear stress boundary condition for an unsteady, tidal flow model is derived through theoretical analysis. The unsteady boundary layer equation is solved for the velocity distribution ...

Abstract: Identifying and removing constraints from bottleneck activities help to reduce uncertainties in construction processes and increases the transparency of project management. The present means of look-ahead planning do poorly ...

Abstract: Vibration signals of complex rotating machinery are often cyclostationary, so in this paper one novel method is proposed to detect and predict early faults based on the linear (almost) periodically ...
