This article demonstrates the alleviation of mutual coupling of a simple and low-cost four-element microstrip array antenna by strafe hayden jacket loading I-shaped slot-type electromagnetic band gap structure in the ground plane.FR-4 glass epoxy is used as dielectric substrate.Moreover, the proposed array antenna shows a better performance in term
In this gfw-utl-ws250 article, the authors present several topics related to the nascent development of a merit-based hiring system in North Macedonia.This paper employs a normative approach.We advocate for a merit-based hiring system, similar to the American model.First, we explore the pressure exerted by the European Commission to adopt a merit-b
The performance of grouting material determines the connection reliability of prefabricated components and the overall safety of the structure.In order to realize the rapid connection of prefabricated components, improve the construction efficiency and improve the quality of component connection.The research group has developed a grouting material
In this work, a comparison of Greek Orthodox religious chants is performed using fuzzy entropy.Using a dataset of chant performances, each recitation is segmented into overlapping time windows, and the s?n nhà màu n?u ??t fuzzy entropy of each window in the frequency domain is computed.We introduce a novel audio fingerprinting framework by compar
Water and soil losses from sloping farmlands potentially contribute to water eutrophication and land degradation.However, few studies explored the combined effects of ridge direction and ridge width on surface runoff and soil losses of sloping farmlands.Twenty-seven experimental plots (8 m long and 4 m wide) with nine treatments (three ridge direct
