For the problems of nonparametric estimation of nonincreasing and symmetric unimodal density functions with bounded supports we determine the projections of estimates onto the convex families of possible parent densities with respect to the weighted integrated squared error We also describe the method of approx imating the analogous projections onto the respective density classes satisfying som...

Abstract: Quantile regression is a flexible and powerful technique which allows to model the quantiles of the conditional distribution of a response variable given a set of covariates. Regression quantile estimators can be viewed as M−estimators and standard asymptotic inference is readily available based on likelihoodratio, Wald, and score-type test statistics. However, these statistics requir...

The time-dependent Stokes equations in twoor three-dimensional bounded domains are discretized by the backward Euler scheme in time and finite elements in space. The error of this discretization is bounded globally from above and locally from below by the sum of two types of computable error indicators, the first one being linked to the time discretization and the second one to the space discre...

Many sensor network applications are based on the knowledge of sensor locations. A priori, some sensors know their position (via GPS). The objective of this paper is to allow positioning of remaining sensors with high accuracy. Existing technologies (e.g. ToA Time of Arival) allow sensors to calculate ranges with their neighbor nodes. A new and original range-based distributed technique, called...
