In this paper, a linear Chebyshev pseudospectral method (LCPM) is proposed to solve the nonlinear optimal control problems (OCPs) with hard terminal constraints and unspecified final time, which uses Chebyshev collocation scheme and quasi-linearization. ...

A numerical model was used to simulate the propagation of internal waves (IW) along the surface layer. The results show that strong water exchange during IW propagation results in strong free surface flow and produces small but distinct free surface wave...

Lateral torsional buckling of beams is a very important issue in the design of steel structures. Currently, this phenomenon is accounted for in a simplified way, namely by determining the critical moment of lateral torsional buckling for the theoretical ...

In this paper we introduce a Gaussian approximation for the achievable downstream bit rate per user in modern broadband and ultra-broadband digital subscriber loop-based access systems. The considered formulation allows one to account for the main charac...

In this paper, a four-node composite cylindrical shell finite element model based on Love?s first approximation theory is proposed to solve the nonlinear vibration of the hard-coating cylindrical shell efficiently. The developed model may have great sign...

The two-side methods of the second order of accuracy are constructed. The formulas give an opportunity to receive upper and lover approximation at each point to the exact solution and define the value of the main error without referring to the right part...

In recent years, meshless methods have gained their popularity, mainly due to the fact that absolutely no elements are required to discretize the problem domain. This is possible due to the nature of the approximation functions used in this method. Appro...

The adjoint method is applied to derive simple integral formulas for the sensitivity study of the Adem Ocean Thermodynamic Model to small variations both in the heat forcing and in the initial and boundary conditions In each formula, the adjoint model...
