We address the planar restricted four-body problem with a small body of negligible mass moving in Newtonian gravitational field three primary bodies nonnegligible masses. assume that two primaries have equal masses and all move circular orbits forming Lagrangian equilateral triangular configuration. This configuration admits relative equilibria for analogous to libration points three-body probl...

Two compact and low loss dual-mode filters are proposed by using degenerate modes of slotted triangular microstrip patch resonators. The geometrical size and radiation loss of the triangular patch are reduced simultaneously by loading both horizontal and vertical slots. The resonant frequencies of two degenerate modes can be easily controlled by varying the dimensions and positions of the slots...

In this paper we describe a method for multiple speech sources separation using an equilateral triangular microphone array. Firstly, the azimuths of horizontal plane are divided into many units and the spatial features of some directions observed by the microphone array are modeled precisely. Secondly, the input mixing signals are segmented into blocks, and then the number of active speakers an...

ABSTRACT This study is concerned with the simulation of viscous flow past three equal diameter circular cylinders in equilateral-triangular arrangement. The hydrodynamic characteristics of cylinders are modelled by a 2Dlattice Boltzmann kernel which is constructed employing Compute Unified Device Architecture (CUDA) interface developed by nVIDIA. Computations using the developed kernel are perf...

We have recently studied a model of monomer adsorption on infinitely long equilateral triangular lattices with terraces of finite width M and nonperiodic boundaries. This study was restricted to the case of repulsive adsorbate-adsorbate first-neighbor interactions but included attractive, repulsive, and negligible second-neighbor interactions. The present work extends this study to the case of ...
