We study the connection between triangulations of a type $A$ root polytope and resonance arrangement, hyperplane arrangement that shows up in surprising number contexts. Despite an elementary definition for chambers has only been computed to $n=8$ dimensional case. focus on data structures labeling chambers, such as sign vectors sets alternating trees, with aim at better understanding structure...

In this paper, small sized array configurations with small number of element are investigated. As the antenna size, the diameter less than 3λo is assumed. The investigated configurations are a non-uniform arrangement, Triangular arrangement and uniform arrangement. The gain characteristics of these configurations is calculated using the method of moment and compared them. As a result, it is fou...

This paper presents Barycentric Coordinates using Closed-Points (BCCP) algorithm to minimize positioning error occurred by AP arrangement form. Triangular AP arrangement form and straight line AP arrangement form were used to include measurement error and conduct simulation in which the presented algorithm and least-square method was used for simulation performance analysis. As result of simula...
