As the world container volumes are soaring, container terminals form a very important chain in the global transportation network. It is a generally accepted view that the modelling of the dynamic and stochastic nature of the container terminal systems using analytical or closed form models is a complicated process and the use of such models is very limited. Hence, this paper presents a simulati...

Crane sequencing in container terminals determines the order of ship discharging and loading jobs that quay cranes (QCs) perform so that the duration of vessels’ stay is minimized. The ship’s load profile, berthing time, number of available bays and QCs are considered. More importantly, clearance and yard congestion constraints need to be included, which respectively ensure that a minimum dista...

Committed to converting the Port of Balboa into a major transshipment hub, Panama Ports Company (PPC) launched in 2006 a $300-million expansion program to increase berthing and stacking space that would almost triple the port capacity. The site’s history of marine-related activities, deteriorating facilities, buried structures, and poor soils mandated significant investment in clearing and prep...

The %V/∆C model of rhythmic class distinction captures syllable complexity rather than rhythm. An alternative rhythm measure will be proposed based on (z-transformed) syllable durations and inspired by the PVI-measure [1]. Some evidence for the existence of isochronous syllable sequences is presented which might provide a new approach towards a classification into stress timed and syllable time...

W you're my age, attention has to be paid to the generation gap. Slacking off leads to a slide into isolation and even ignorance. It isn't always easy for my generation who are more at home with paper, print and books than iPhones, iPads and touch screens. But I will also be the first to recognize the importance of change. Last year we planned our annual Wisconsin Turfgrass Association Winter T...

The electronic structures and excitation properties of dye sensitizers determine the photon-to-current conversion efficiency of dye sensitized solar cells (DSSCs). In order to understand the different performance of porphyrin dye sensitizers YD2 and YD2-o-C8 in DSSC, their geometries and electronic structures have been studied using density functional theory (DFT), and the electronic absorption...

This section contains an overview of the different functional areas of a marine container terminal and a summary of the main types of container handling systems. The main advantages and disadvantages of each type of handling system are also summarized without focusing on technical details. 2.1 Functional Areas of Terminal Operations As every other terminal, a container terminal is a complex sys...
