Abstract Background In 2017, smaller container ports handled approximately 22% of total containerized cargo. Nowadays liner operators are calling on those with larger ships and demanding fast efficient turnaround the in port. This is possible only if berth has right capacities, working properly achieves a good productivity level. Methodology Productivity level does not depend quay crane capacit...

The performance system at the container terminal Semarang Container Terminal (SCT) is not yet good, it can be seen from average dwelling time which still long. Dwelling optimization needs to done in order get a balance of projected increases during trading and compensate for various limitations facilities infrastructure. One them handling procedure using an application, namely cost operating ap...

Multi-terminal high voltage direct current (HVDC) systems, together with AC transmission systems and source converters (VSCs), form hybrid AC/DC grids complex dynamic transient interactions. VSCs characterization taking into account DC- AC-side dynamics in order to study these interactions is not yet well solved. This paper presents a three-port transfer admittance-based matrix model of that ca...

This paper intends to assess the potential impacts of future SLR on operability berthing structures and estimate in monetary terms adaptation costs it. To do this, three scenarios are considered, two corresponding last assessment report IPCC (RCP4.5 RCP8.5) other being a high-end scenario (HES), with low probability occurrence but physically possible. The research is focused case study Tangier-...

Maritime security and surveillance have become one of the main areas in managing overall situational awareness.For example, growing importance maritime traffic cross-border trade has created new pressures to develop newtechnologies for accident prevention, especially ports. safety is also a matter concern continuitymanagement. Automatic ship alarm systems, coastal radars cameras are not alone s...

This paper discusses the problem of scheduling quay cranes, the most important equipment in port terminals. A simulation model is developed for evaluating time of quay cranes. Then a dynamic scheduling model using objective programming for quay cranes is developed based on genetic algorithm approach. Finally, numerical experiments on a specific container terminal are made for propose approach. ...

Abstract With the increasing volume of container freight transport, future port planning is crucial. Simulation models provide a means to gain insight in effects terminal expansions. Detailed simulations incorporate berth allocation: assigning vessels time and location at quay wall, where vessel loaded unloaded. This article develops decision for both offline preliminary online recovery this pl...

In this study, expressions for the radiation quality factor Q and the input impedance seen at any terminal of a multiport antenna are derived. It is shown computationally that because of the possibility to adjust the antenna current distribution through suitable feeding/loading a multiport antenna can perform lower Qs than a similar single-port antenna. © 2008 Wiley Periodicals, Inc.

A wireless multi-hop virtual cellular network (VCN) was recently proposed to avoid the large peak transmit power, resulting from the high transmission rates expected for future mobile communication systems. In VCN, calls hop through several links to reach the central port, which is the gateway to the network. With the use of a routing algorithm based on the total uplink transmit power minimizat...
