The scheduling method of shiplock has a strong influence on the improvement of shiplock capacity. On the condition that the number of the ships waiting for the lock was relatively stable, the paper constructed an optimization model for joint scheduling of double line shiplock based on the nonlinear goal programming. The hard constraints included that the number of ships arranged in the shiplock...

It is a fact that not only ships, but also seafarers and passengers vanish without a trace at sea, be it in the past or in present times. Several examples for this phenomenon are given. A scheme of the ship conditions found after discovering that single persons or even whole crews had disappeared from board is provided as an orientation, before describing in detail the more than 18 reasons for ...

In this paper, we present a robust and accurate multiple ship detection system for port surveillance. First, water region is detected using a region-based technique. Second, ships are located by a cabin detector for the same port surveillance sequences. Third, a verification process is performed to remove the false detections of ships using the detected water region as contextual cues. We have ...

The Royal Australian Air Force (RAAF) conducts maritime surveillance operations in order to deter non-state threats such as terrorism or illegal fishing. RAAF aircraft search various areas of ocean in order to classify as many ships as possible in the shortest possible time. This resembles the traditional Travelling Salesman Problem (TSP) but with many interesting variations – the “cities” (shi...

During January 1-December 2, 2002, CDC's Vessel Sanitation Program (VSP), which conducts surveillance for acute gastroenteritis (AGE) on cruise ships with foreign itineraries sailing into U.S. ports received reports of 21 outbreaks of AGE on 17 cruise ships. Of the 21 outbreaks, nine were confirmed by laboratory analysis of stool specimens from affected persons to be associated with noroviruses...

Economics and energy aspects of food irradiation were also discussed. Disinfestation of bulk grain, of bagged flour, preservation (radunzation) of packaged beef cuis and salmonella elimination from (radicidation of) poultry with electron accelerators, using electron beams or X-rays, were computed to be economically feasible and competitive. Deiailed analyses of the energy requirements of food p...
