A substrate-integrated waveguide (SIW) antenna is an implementation of a waveguide antenna in a microstrip antenna.The microstrip antenna, as a low-profile antenna, suffers from narrow impedance bandwidth.This paper proposes a novel bandwidth maison alhambra libbra enhancement method for solving a narrow impedance bandwidth.Bandwidth enhancement wa
Himalayan Alpine pasture occurs at high altitude mountains in between the tree line and perpetual snow line.These constitute one of the important land cover.These pastures contain very good grasses and medicinal plants thus traditionally tribal people depend on these pastures for grazing their animals during summer.75% of the total alpine pastures
In this paper, the seismic response of a steel truss arch bridge subjected to near-fault ground motions is studied.Then, the idea of applying buckling restrained braces (BRBs) to a steel truss arch bridge in near-fault areas is proposed and validated.Firstly, the basic 537bk-2302 characteristics of near-fault ground motions are identified and disti
