Local Path Fitting: A New Approach to Variational Integrators
D S Vlachos, O T Kosmas
In this work, we present a new approach to the construction of variational integrators. In the general case, the estimation of the action integral in a time interval $[q_k,q_{k+1}]…
High Order Phase-fitted Discrete Lagrangian Integrators for Orbital Problems
O. T. Kosmas, D. S. Vlachos
In this work, the benefits of the phase fitting technique are embedded in high order discrete Lagrangian integrators. The proposed methodology creates integrators with zero phase l…
Operational Optimal Ship Routing Using a Hybrid Parallel Genetic Algorithm
O. T. Kosmas, D. S. Vlachos
Optimization of ship routing depends on several parameters, like ship and cargo characteristics, environmental factors, topography, international navigation rules, crew comfort etc…
Simulated Annealing for Optimal Ship Routing
O. T. Kosmas, D. S. Vlachos
A simulated annealing based algorithm is presented for the determination of optimal ship routes through the minimization of a cost function. This cost function is a weighted sum of…
Gamma Ray Spectrum Unfolding Using Derivative Kernels
D. S. Vlachos, O. T. Kosmas
The unfolding of a gamma ray spectrum experience many difficulties due to noise in the recorded data, that is based mainly on the change of photon energy due to scattering mechanis…
Synchronization in Complex Systems Following the Decision Based Queuing Process: The Rhythmic Applause as a Test Case
D. Xenides, D. S. Vlachos, T. E. Simos
Living communities can be considered as complex systems, thus a fertile ground for studies related to their statistics and dynamics. In this study we revisit the case of the rhythm…
