The focus of attention from regulatory bodies in Australia with respect to air pollution emissions is for land-based industries and activities; as such, little attention has been paid to emissions from ships operating in Australian ports. Emissions standards for ships in general are not included in Australian legislation, although the international standard, MARPOL 73/78, sets limits on emissio...

ions A first-order abstraction in the ρpg-calculus consists of two object port graphs for the leftand the right-hand sides, and an arrow node embedding the correspondence between the two sides. The arrow node has two particular ports, a handler port p0 and a black hole port bh. Some restrictions must be imposed on the connectivity of these two types of ports. A handler port can be connected onl...

This paper presents an extension of the BIP component framework to hierarchical components by considering also port sets of atomic components to be structured (ports may be in con ict or ordered, where a larger port represents an interaction set with larger interactions). A composed component consisting of a set of components connected through BIP connectors and a set of ports representing a su...

2014 Linear reciprocal resistive n-ports manifest convex (downward concave) property in view of their positive definite character. Several useful theorems for resistive n-ports are proved by electrical circuit considerations. The suggested line of physical reasoning via n-ports is potent for deriving a variety of matrix inequalities for positive definite operators. Tome 41 No 5 1 er MARS 1980 L...

This paper examines how two geographically separated ports compete for a market consisting of manufacturing firms located between the two ports. There is a firm in each port, and these two firms, taking the infrastructure provided by their governments as given, compete in a Bertrand sense. The governments, however, can also compete in terms of investment in infrastructure. This paper shows that...

This study presents an evaluation of the relative efficiency of sixteen container ports in Sub-Sahara Africa using three DEA models namely CCR, BCC and Super-Efficiency over the year 2012. The CCR and BCC models are used to estimate the technical and scale efficiency while the super-efficiency technique provides a ranking of efficient ports. The efficiency results indicate that on average the i...
