Here we introduce a combined experimental and descriptive approach (termed resurrection ecology) to reconstructing historical perturbations, pointing out how direct tests with sediments and hatched resting eggs complement the traditional descriptive calculation of microfossil fluxes. In the Keweenaw Waterway, a freshwater estuary off Lake Superior, turn-of-the-century copper mining impacted the...

Sediment trend analysis (STA) is a technique that determines the net patterns of sediment movement and their dynamic behavior or stability. The data required are the complete particle size distributions obtained from bottom grab samples collected in a regular grid over the area of interest. Appendix 1 provides the particular details of how STA is undertaken. Because many contaminants are known ...

We examine spatial competition along a waterway when shippers are distributed over space. Competition is between barge and rail companies and among barge companies. Equilibrium prices are derived for two variations: oligopolistic rivalry between barge and rail operators, and oligopolistic rivalry among barge operators with terminals located at different points on the waterway. In the first vari...

Informatisation of the public administration Slovak Republic aims to create a functional architecture integrated information system. This system also includes development Agenda systems that provide electronic services in most automated mode, according principle all at once. In field water transport, there is currently no fully agenda Creating an Information System (AIS) will allow multi-channe...

The paper gives a general description of the Danube waterway data management in Croatia. For this purpose, we initiated the development of a specialized geographic information system (GIS), the so called River IS, which provides efficient waterway related data management for the Croatian part of the Danube River. In addition, Croatian activities in the Pan-European Programme Consortium Operatio...

Inland waterway networks are likely to go through heavy changes due to a will in increasing the boat traffic and to the effects of climate change. Those changes would lead to a greater need of an automatic and intelligent planning for an adaptive and resilient water management. A representative model is proposed and tested using MDPs with promising results on the water management optimization. ...

In recent years, single object tracking has been extensively studied and achieved much development. However, multiple objects tracking is still an issue that remains to be addressed. Generally speaking, existing multiple objects tracking methods employ a manner of simultaneously tracking each object respectively. In this paper, we develop a multiple ship tracking algorithm based on deformable p...
