Several equivariant estimators of multivariate location and scatter are studied, which are highly robust, have a controllable finite-sample efficiency and are computationally feasible in large dimensions. The most frequently ...

An analog circuit that implements a radial basis function network is presented. The proposed circuit allows the adjustment of all shape parameters of the radial functions, i.e., amplitude, center and width. The implemented ...

The DPG method with optimal test functions for solving linear quadratic optimal control problems with control constraints is studied. We prove existence of a unique optimal solution of the nonlinear discrete problem and ...

This note shows the equivalence of different instrumental variables estimators to solve the endogeneity problem in linear models when valid instruments are available. We demonstrate that the exclusion restriction estimator ...

The reference works about control charts consider the statistical parameters as known to calculate the control limits. However, in the last decades, the literature about SPC (Statistical Process Control) has indicated a ...

Abstract. Visual model ofan object is presented as composition ofa model-shape function and a model-pattern function. Nonuniformity ofa pattern is defined as a quadratic form related to the gradient ofintensity. F or ...
