This paper deals with accuracy improvement of handwritten character recognition by the GLVQ (generalized learning vector quantization). In literature , the way of combining the FDA (Fisher discriminant analysis) and the GLVQ was investigated and evaluated to be effective for handwritten Chinese character recognition employing the minimum Euclidian distance classifier. In this paper, the project...

In recent years, Topology Optimization (TO) gained interest in the scientific community. It assists finding best arrangement of material a design volume. The classical approach named ”Solid Isotropic Material with Penalization” (SIMP) associates fictitious density to each finite element domain. While SIMP is described as an implicit which can lead problems dimensionality variables, explicit met...

An interesting method has been applied by David Alexandrovich Aitoff modifying the equidistant transversal azimuthal projection so that it can be used for planisphere representations. Such transformations were generalized Karheinz Wagner long after Aitoff. In this study, transformation is discussed, and to streographic projection. This modification examined in terms of distortions compared with...

The theory of anisotropic generalized plane strain line forces and dislocation lines is embedded in three-dimensional elasticity point densities. Embedding real space achieved by slicing reciprocal using the projection-slice theorem.

This paper deals with the stability of null-space velocity control algorithms in extended operational space for redundant robots. We compare the performance of the control algorithm based on the minimal null-space projection and generalized-inverse-based projection into the Jacobian nullspace. We show how the null-space projection affects the performance of the null-space tracking algorithm. Th...

The paper investigates the properties of general reduced order models obtained by projection of a high order system. It answers questions such as are any two models of different orders related by a projection? Is it possible to obtain the same reduced order model using different projections? How to find, if it exists, a projection that relates the two models? Etc. It is shown that answers to th...

Chernoff's bound binds a tail probability (ie. Pr(X ≥ a), where a ≥ EX). Assuming that the distribution of X is Q, the logarithm of the bound is known to be equal to the value of relative entropy (or minus Kullback-Leibler distance) for I-projection ^ P of Q on a set H {P : E P X = a}. Here, Chernoff's bound is related to Maximum Likelihood on exponential form and consequently implications for ...
