One of the big problems in wireless communication channels is the multipath fading. Almost all environments suffer for this multipath which is caused when the receiver receive more than one signal path because of diffraction, reflection, shadowing and scattering. Each path has different properties which cause more complexity in the receiver end to recover the transmitted signal especially in the
In this work, the effect of annealing temperature on the formability of three different alloys (Brass CuZn30, Galvanized steel and 1060 Aluminum alloy) sheets was investigated both theoretically and experimentally. A range of annealing temperature, strain rate, and different lubrication conditions to determine best parameters for satisfactory metal forming.
The rehabilitation of an existing cracked pavement made of asphalt can be simply done by the installation of new asphalt layers. Due to external forces from traffic and natural temperature variations, existing cracks or joints rapidly propagate out of the old pavement into the new asphalt overlay.
