Sharp non-asymptotic performance bounds for and Huber robust regression estimators
A quantitative study of the robustness properties of the and the Huber M-estimator on finite samples is presented. The focus is on the linear model involving a fixed design matrix and additive errors restricted to the ...
ON THE p-MEDIAN POLYTOPE AND THE INTERSECTION PROPERTY: POLYHEDRA AND ALGORITHMS
(SIAM PUBLICATIONS, 2011)
We study a prize-collecting version of the uncapacitated facility location problem and of the p-median problem. We say that the uncapacitated facility location polytope has the intersection property if adding the extra ...
Statistical properties for an open oval billiard: An investigation of the escaping basins
Statistical properties for recurrent and non recurrent escaping particles in an oval billiard with holes in the boundary are investigated. We determine where to place the holes and where to launch particles in order to ...
Effect of an experimental silica-nylon reinforcement on the fracture load and flexural strength of bisacrylic interim partial fixed dental prostheses
Statement of the problem. Materials used in the fabrication of interim restorations usually have mechanical properties inferior to those used in definitive prostheses. Various techniques may be used to reinforce these ...
Heat transfer in fixed bed: a model non-linearity approach
(Elsevier B.V., 2000-06-01)
Studies have been carried out on the heat transfer in a packed bed of glass beads percolated by air at moderate flow rates. Rigorous statistic analysis of the experimental data was carried out and the traditional two ...
Connections between the Sznajd model with general confidence rules and graph theory
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
The Sznajd model is a sociophysics model that is used to model opinion propagation and consensus formation in societies. Its main feature is that its rules favor bigger groups of agreeing people. In a previous work, we ...
Propriedades de escala e cascatas de bifurcações em mapas unidimensionais discretos
(Universidade Estadual Paulista (UNESP), 2018-02-28)
Neste trabalho estudamos o decaimento das órbitas para os pontos fixos em bifurcações distintas em mapeamentos unidimensionais não lineares discretos. Consideramos o mapa Gauss, analisamos o diagrama de órbitas e estudamos ...
Uso de microalgas para adsorção do corante rodamina b empregado na indústria de tingimento de ágata
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-09-03)
Rhodamine B (RhB) has been widely used in dyeing of semiprecious stones (agate), which are exported from the Southern Brazil, and in this dyeing process, colored effluents are generated. Then, the objective of this work ...
Scaling properties of the regular dynamics for a dissipative bouncing ball model
(Elsevier B.V., 2007-12-01)
Some scaling properties of the regular dynamics for a dissipative version of the one-dimensional Fermi accelerator model are studied. The dynamics of the model is given in terms of a two-dimensional nonlinear area contracting ...
