In this paper a particle swarm optimization (PSO) algorithm is presented to design a compact stepped triangle shape antenna in order to obtain the proper UWB bandwidth as defined by Brides FCC.By changing the various cavity dimensions of the antenna, data to develop PSO program in MATLAB is achieved.The results obtained from the PSO algorithm are a
There are stringent requirements on the vertical movement of a ground surface when using artificial ground freezing method to reinforce a shield tunnel in a city.This paper focused on the tunnel of Nanjing Metro Line Two between Yixianqiao and Daxinggong.Based on the discrete element thermo-mechanical coupling theory, the horizontal freezing reinfo
Epitaxial lateral growth will be required if complex diamond-based device architecture, such as, for example, Metal-oxide-semiconductor Field-effect transistors (MOSFETs) or epitaxial lateral overgrowth (ELO) substrates, need to be developed for high-power applications.To this end, undoped and doped non-planar homoepitaxial diamond were overgrown o
Sustainable socio-economic development largely depends on the sustainability of the Machine Control energy supply from economic, environmental, and public health perspectives.Fossil fuel combustion only meets the first element of this equation and is hence rendered unsustainable.Biofuels are advantageous from a public health perspective, but their
Spiders exist in every place and ecosystem.Spiders in tropical regions are particularly poisonous and can be dangerous to humans.Nearly 20,000 spider species are known, and almost all are venomous, although only 60 species worldwide are poisonous in humans.In Brides our area, eight species are reported as poisonous in humans.Although most cases of
