This research investigates how the number of elements affects the monopole antenna's planar array's directivity. This study also takes into account the antenna's effect on the whole field it radiates. The monopole antennas are arranged in a planar co

We present a simple visual description of the topology of the space of three-dimensional rotations, requiring just intuition, imagination and no advanced math.

In this study, we propose an improvement to the direct mating method, a constraint handling approach for multi-objective evolutionary algorithms, by hybridizing it with local mating. Local mating selects another parent from the feasible solution spac

The unique properties of anisotropic and composite particles are increasingly being leveraged in modern particulate products. However, tailored synthesis of particles characterized by multi-dimensional dispersed properties remains in its infancy and

In this paper, we draw diagrams of yinyang, wuxing and bagua as the McKay quivers of the groups of order 2, of order $5$ and of order $2^3$.
Comment: The orientations of the diagrams in Section 2 are cerrected

Pranata mangsa is a local knowledge based on a calendrical system utilized historically by Javanese peasant farmers in conducting their agricultural activities in cultivating plants and vegetation. It is also used by fishermen to guide them not only

In this paper we point out an interesting geometric structure of nonnegative metric curvature emerging from the hyperspaces of decomposable, non-locally connected homogeneous continua, where "smooth" and "non-smooth" partitions live together, similar

We examine a fundamental material property called Poisson's ratio, which establishes the relationship for the relative deformation of a physical system in orthogonal directions. Architects and engineers have designed advanced systems using repeating
