A predictive estimator for estimating the parameter of binomial distribution is suggested. This estimator aims to maximize the expectation of expected log-likelihood. The results given by this estimator are superior to those given by the maximum likelihood estimator in terms of t...

Gaussian elimination method is one of the widely used methods for solving linear equations. An interval version of Gaussian elimination method has been used by simply replacing each real arithmetic step by the corresponding interval arithmetic step. Two interval arithmetics techn...

This paper studies Strassen’s algorithms for fast multiplication of two finite dimensional matrices. However, one pertinent issue that has deterred Strassen’s scheme from been considered for practical usage is determining the cross-over point. In this light, large matrices with d...

This paper is presenting a fourth-order nonlinear conjugate gradient method in large scale optimization. This method solves unconstrained optimization problems. It is based on a nonlinear polynomial approximation of the objective function. The idea is to approximate the minimizin...

In this paper we calculate the Witt groups of P1. It's a known result, but we calculate it by another method: we use the localisation theorem of Balmer and the excision theorem of S. Gille.

In this paper, we shall continue a study of the CS-recovery of signals studied in [1]. Under the assumption that a m × n matrix A obeys the RIP of order s we decompose the space of unknown vectors into sets M0; M1; · · · ;M7 de ned by a bias function px on a good location T0 = {1...

Bernstein operators constitute a powerful tool allowing one to replace many inconvenient calculations performed for continuous functions by more friendly calculations on approximating polynomials. In this note we study a modi cation of Bernstein type operators and prove in partic...

The aim of this paper is to introduce the two notions of filtrations and deductive systems in BCL+ algebras, and investigate some of their related properties. Using this, we prove that the filtration is subalgebra of BCL+ algebras; we also prove that the filtration of BCL+ algebr...

In this note we compute values of global linear Harbourne constants over arbitrary fields for up to ten lines. These invariants have appeared recently in the discussions around the Bounded Negativity Conjecture, see [1]. They seem to be of independent interest also from the point...

Based on the very old methods of solving linear systems of simultaneous congruences, the Chinese Remainder Theorem is still an irreplaceable tool in Computing, Signal Processing and Information security. We demonstrate its potential by considering an example of an application con...
