Interacting dark sector with variable vacuum energy
(Amer Physical Soc, 2013-10)
We examine a cosmological scenario where dark matter is coupled to a variable vacuum energy while baryons and photons are two decoupled components for a spatially flat Friedmann-Robertson-Walker spacetime. We apply the χ2 ...
Automation In Fault Detection Using Neural Network And Model Updating

Improved finite element model of a tall building in Santiago of Chile using seismic records
(Universidad de Chile, 2021)
Historically the structural models used for structural design have been developed using accepted parameters (damping, the level of cracking of reinforced concrete elements, the magnitude and distribution of masses and ...
Model error estimation using the expectation maximization algorithm and a particle flow filter
(Society of Industrial and Applied Mathematics, 2021-03)
Model error covariances play a central role in the performance of data assimilation methods applied to nonlinear state-space models. However, these covariances are largely unknown in most of the applications. A misspecification ...

Modified barrier method for optimal power flow problem
(2004-12-01)
In this paper is presented a new approach for optimal power flow problem. This approach is based on the modified barrier function and the primal-dual logarithmic barrier method. A Lagrangian function is associated with the ...
