This paper deals with Feedback/Feedforward (FB/FF) control of a gantry crane system intended for the transport payloads that take values over known interval. It is also assumed affected by unmeasurable disturbances. A new 2DoF architecture proposed whose purpose to speed up horizontal payload transition while minimizing its oscillations. The main features design procedure are as follows: (1) ou...

background: the purpose of this study was to investigate the various gantry angle and ssd dependencies of tld and mosfet dosimeters. materials and methods: lif (mg) tld and mosfet were used in this study. dosimeter systems were calibrated and then irradiated at various gantry angle and ssd by applying 6 mv photon energy. results: based on the results, mosfet changes were found to be in 2% range...

The growths of containerization and transporting goods in containers have created many problems for ports, especially with the development of operation equipments produced by port machine manufacturer. A simulation study was proposed to a new container terminal handling technology, which is comprised of twin 40-foot quay cranes, a low bridge allocation system and twin 40-foot rail mounted gantr...
