A new approach for constructing variational integrators is presented. In the general case, the estimation of the action integral in a time interval [t"k,t"k"+"1] is used to construct a symplectic map (q"k,q"k"+"1)->(q"k"+"1,q"k"+"2). The basic idea, is that only the partial derivatives of the estimated action integral of the Lagrangian are ...

In this article we present a simulated annealing based algorithm for the determination of optimal ship routes through the minimization of a cost function defined as a weighted sum of the time of voyage and the voyage comfort (safety is taken into account too). This cost function is dependent on ...

LMEF is a program written in MATLAB, to calculate the coefficients of a linear multi-step method (explicit, implicit or backward differentiation formulas) with algebraic and/or exponential fitting, for the numerical solution of first order ordinary differential equations. Moreover, LMEF calculates the local truncation error and in the case of exponential ...

A parametric method is presented for calculating the directional wave spectrum from vertical and horizontal accelerations of a floating buoy. These measurements are obtained from accelerometers attached on board the buoys of the POSEIDON network. The method assumes the superposition of two independent wave trains giving a better approach to ...
