a digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. the system is designed in ka-band for a dvb-s2 satellite link. we use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. the six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. this approa...

In a container terminal, many operations occur within the storage area: containers import, containers export and containers shifting. All these operations require the respect of many rules and even laws in order to guarantee the port safety and to prevent risks, especially when hazardous material is concerned. In this paper, we propose a hybrid architecture, using a Cellular Automaton and a Mul...

This article deals with the extremely difficult problem faced by a large number of smaller ports: how to enable small container terminals simultaneously receive two ships post-Panamax size, and at same time provide effective transshipment operations on an individual terminal subsystem, which would fast turnaround ship in port possibility increase annual traffic. For this purpose, simulation app...

Due to the significant advantages of low cost, integrated multi-port hybrid DC circuit breakers (M-HCBs) with a reduced number devices have attracted extensive attention for fault blocking in multi-terminal VSC-HVDC system. However, current topology exploration by researchers is random, uncertain, and time-consuming. In order provide more new cost-effective topologies, this paper innovatively p...

Background: Laparoscopic Surgery (LS) may be associated with many port site complications such as hernia, bleeding, infection, subcutaneous emphysema and ugly scars. Some of these complications are serious such as obstructed port site hernia . Rate of these complications is low depending  on size and site of the port incision, type of the trocar that it is used, the condition of  the patient a...

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...

In this work, we study the integrated berth and crane scheduling problem in a tidal port with multiple terminals, considering uncertainties, tides, maximum coverage of cranes interference between cranes. For coping certain number randomly generated samples are used to evaluate solutions, slack variables introduced reduce impact caused by variation vessel arrival operational efficiency. A novel ...
