The paper presents a new approach to the computational treatment of polyreaction kinetics. This approach is characterized by a Galerkin method based on orthogonal polynomials of a discrete variable, the polymer degree (or chain length). In comparison with the known competing approaches (statistical moment treatment, Galerkin methods for continuous polymer models), the suggested method is shown ...

Following the suggestion made by Johnson (Johnson B.A., 2015), a polygonbased cross validation (CV) method is compared to the pixel-based CV method to classify different levels of land cover categories using a single-date Landsat 8 image and time series of Landsat TM images. Also, different variants of band combinations, with and without the thermal bands, were considered. The results demonstra...

Geometric iterative methods, including progressive approximation and geometric interpolation are efficient for fitting a given data set. With the development of big technology, number points has become massive, least-squares (LSPIA) is generally applied to fit mass data. Combining Schulz method calculating Moore–Penrose generalized inverse matrix with traditional LSPIA method, this paper presen...

In a recent paper, Baader and Schulz presented a general method for the combination of constraint systems for purely positive constraints. But negation plays an important role in constraint solving. E.g., it is vital for constraint entailment. Therefore it is of interest to extend their results to the combination of constraint problems containing negative constraints. We show that the combined ...

This article deals with the mathematical and the numerical aspects of the Fredholm integral equation of the second kind arising as a result of the heat energy exchange inside a convex and non-convex enclosure geometries. Some mathematical results concerning the integral operator are presented. The Banach fixed point theorem is used to guarantee the existence and the uniqueness of the solution o...

this paper attempts to determine the relationship between women’s participation and their empowerment. empowerment is a process whereby women become able to organize themselves to increase self-reliance and to assert their independent right to make choices and control resources. empowerment in this study was adopted from rowlands (1997) and schulz, et al. (1993) which has two levels, individual...
