Recent developments in computational fluid dynamics are enabling accurate simulations of full scale ship hydrodynamic flow. In particular, Cartesian-grid techniques such as volume-of-fluid and immersed boundary methods expedite computational simulations of unsteady breaking wave flows around complicated ship geometries. However, there are still a number of important numerical and modeling issue...

this study analyses the concept of cost functions for semi-automated straddle carrier (sc), rubber tyred gantry (rtg) and automated rail mounted gantry (rmg) container yard operating cranes. it develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

Major changes in the size, shape and performance of ships will create a severe challenge to the technical skills of ship structural designer. Fortunately, the groundwork has alreadY been laid for the technology required to support him. The na~;re and quality of this technical base is discussed and gaps are identified. The serious need for closing the interface between researcher and designer is...

although liability under general tort and contract law principles is not limited to a certain amount, liability arising under a carriage contract is limited by the majority of international transport conventions and national legislatures and, there are certain reasons given to justify the “essential departure from the current rules of civil law” and it is common for the liability of the carrier...

To understand the impact ofmicroplastic (MP) pollution to aquatic ecosystems, it is important to identify the mechanisms of interaction with organisms. Exposure experiments, like the study of Sussarellu et al. (1) recently published in PNAS, may provide such insights. However, the results of dose–response experiments must always be interpreted in light of environmental concentrations, and the e...

Fresh mushroom compost is a byproduct of the edible mushroom (Agaricus bisporus) industry and represents the composted growing substrate that remains after a crop has been harvested to completion. Thirty samples were obtained from commercial mushroom farms in southeastern Pennsylvania and sent to a laboratory for analysis to determine plant nutrient content, bulk density, and particle size dist...

We present an optimization model for the yard allocation process in an automotive transshipment terminal. The cars arrive and depart by ships in large batches and the yard planners have to dynamically assign incoming cars to parking rows. The integer linear programming model has been implemented in a commercial solver (CPLEX). We will present at the conference the model, the CPLEX computational...
