چکیده
This paper proposes new closed expressions of self-impedance using the Method Moments with Point Matching Procedure and piecewise constant linear basis functions in different configurations, which allow saving computing time for solution wire antennas complex geometries. The have complexity O(1) well-defined theoretical bound errors. They were compared an adaptive numerical integration. We obtain accuracy between 7 16 digits depending on chosen function segmentation used. Besides, involved calculation terms was evaluated required by adaptative quadrature integration same problem. Expressions a run-time bounded 50 200 times faster than assuming full computation all expressions.

Closed Form expressions for moments of the beta Weibull distribution
The beta Weibull distribution was first introduced by Famoye et al. (2005) and studied by these authors and Lee et al. (2007). However, they do not give explicit expressions for the moments. In this article, we derive explicit closed form expressions for the moments of this distribution, which generalize results available in the literature for some sub-models. We also obtain expansions for the ...
