This work aims at discussing the cubature Kalman filter (CKF) performance when applied to a highly nonlinear problem: the artificial satellites orbit determination problem, using real global positioning system (GPS) data. The CKF is a nonlinear filter based on a third-degree spherical–radial cubature rule, which allows to numerically compute multivariate moment integrals in the Bayesian filter and...
Brazil is the world's largest producer of sugarcane and has a great potential for sugar and ethanol production. Sao Paulo is its main producer state and produced more than 367,450 million tons of sugarcane in 2012/2013 harvest season. In this study, operations research techniques are applied to obtain optimum locations for establishing new and/or to expand sugar and ethanol mills in the state of Sao...
