Análise de estruturas de aço com ligações semi-rígidas
(Universidade Federal de Minas GeraisUFMG, 1997-04-11)
A method for the calculation of the initial tangent stiffness and the ultimate secant stiffness of flexible connections was presented. Local flexibilities, in elastic phase, of rigid connection where evaluated.It was ...
Design Analysis of Omnidirectional Single Reflector Antennas Synthesized for a Cosecant Squared Coverage in Elevation Plane
(Ieee, 2019-01-01)
This work explores a Geometrical Optics based procedure to design axis-symmetric single reflector antenna to offer omnidirectional coverage with an arbitrary radiation pattern in the elevation plane. The reflector surface ...
