Energy drift in reversible time integration
Energy drift is commonly observed in reversible integrations of systems of molecular dynamics. We show that this drift can be modelled as a diffusion and that the typical energy error after time T is O( √ T ). PACS numbers: 45.10.−b, 05.45.Pq In simulations of conservative systems, the energy H is usually monitored as a check on the calculation. In symplectic integration of Hamiltonian systems,...
متن کاملEnergy Drift in the Numerical Integration of Hamiltonian Problems
Abstract: When approximating reversible Hamiltonian problems, the presence of a “drift” in the numerical values of the Hamiltonian is sometimes experienced, even when reversible methods of integration are used. In this paper we analyze the phenomenon by using a more precise definition of time reversal symmetry for both the continuous and the discrete problems. A few examples are also presented ...
متن کاملReal-time Integration of Energy Storage
Increasing dynamics in power systems on account of renewable integration, electric vehicle penetration and rising demands have resulted in the exploration of energy storage for potential solutions. Recent technologyand industry-driven developments have led to a drastic decrease in costs of these storages, further advocating their usage. This thesis compiles the author’s research on optimal inte...
متن کاملSensory Updates to Combat Path-Integration Drift
Even without sensory input, an animal can estimate how far it hasmovedby integrating its velocity, a process called path integration. The entorhinal cortex (EC) and hippocampus seem to be involved in path integration, and in an animal’s perceived location in space. However, path integration is highly susceptible to accumulating errors. A real animal avoids this problem by incorporating sensory ...
متن کاملEnergy-Efficient Emplacement of Reversible DC Traction Power Substations in Urban Rail Transport through Regenerative Energy Recovery
Due to the high potential of urban rail transport systems as an effective solution to improve urban mobility services, these systems have faced an increasing demand in recent years. High capacity, reliability and absence of local emissions are some of the most promising advantages of these transportation systems. However, with the increase in capacity demands, energy costs and environmental ...
