In this paper, the problem of inverting regular matrices with arbitrarily large condition number is treated in double precision defined by IEEE 754 floating point standard. In about 1984, Rump derived a method for inverting arbitrarily ill-conditioned matrices. The method requires the possibility to calculate a dot product in higher precision. Rump’s method is of theoretical interest. Rump made...

Automated fault forecasting proactivity offers a promising closed-loop approach for conventional network failure management activities. Automated intelligent failure forcasting requires the capability to prefilter the observation data so as to remove irrelevant features or factors from multi-dimensional observation data. In this paper, we propose a new hybrid methodology of combining the rough-...

‎in this paper a nonlinear backward parabolic problem in one‎ ‎dimensional space is considered‎. ‎using a suitable iterative‎ ‎algorithm‎, ‎the problem is converted to a linear backward parabolic‎ ‎problem‎. ‎for the corresponding problem‎, ‎the backward finite‎ ‎differences method with suitable grid size is applied‎. ‎it is shown‎ ‎that if the coefficients satisfy some special conditions‎, ‎th...

In Long Term Evolution-Advanced (LTE-A) networks, Device-to-device (D2D) communications can be utilized to enhance the performance of multicast services by leveraging D2D relays to serve nodes with worse channel conditions within a cluster. For traditional D2D relay schemes, D2D links with poor channel condition may be the bottleneck of system sum data rate. In this paper, to optimize the throu...

This paper proposes a method of generating valid integer Benders cuts for a general class of integer programming problems. A generic valid Benders cut in disjunctive form is presented rst, as a basis for the subsequent derivations of simple valid cuts. Under a qualiication condition, a simple valid Benders cut in linear form can be identiied. A cut generation problem is formulated to elicit it....

This paper proposes an algorithm to extract a target region from a color image. The algorithm utilizes the active net for stable target extraction. In order t o extend the original active net for color image analysis, the image energy function of the net is defined by the function, called the Ratio Histogram, of the histogram backprojection method. Since ratio histogram is computed from both co...
