In several applied fields, multimodality assessment is a crucial task as previous exploratory tool or for determining the suitability of certain distributions. The goal this paper to present utilities R package multimode, which collects different and testing non-parametric approaches number modes their estimated location. Specifically, some graphical tools (SiZer map, mode tree forest) are prov...

The R-Mode system is a terrestrial navigation currently under development, which exploits existing means of medium frequency radio transmission. positioning and timing performance depends on the estimation signals' phase offset, from ranging information derived. For an analogous problem such as single-tone estimation, Cramér-Rao bound (CRB) describes minimal achievable in mean squared error sen...

We investigate properties of r-modes characterized by regular eigenvalue problem in slowly rotating relativistic polytropes. Our numerical results suggest that discrete r-mode solutions for the regular eigenvalue problem exist only for restricted polytropic models. In particular the r-mode associated with l = m = 2, which is considered to be the most important for gravitational radiation driven...

in the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. first, governing formulation in transverse electric field mode (te) is obtained using maxwell equations. then, an algorithm based on a finite difference scheme and matrix algebra is presented. the algorithm is then implemented in a comp...
