-A polarimetric radar navigation system makes use o f polarization rotating twist-grid retroreflectors in order to navigate a confined waterway, even in inclement weather or after dark. Despite the polarization diversity offered by such a radar target, depolarization allows significant cross-polar clutter to obscure the reflector return. A novel modular neural network solution integrates an ada...

Managing models and schemas pertaining to different parts of the marine information domain is an important part of the U.S. Coast Guard R&D Center's proposed Waterway Information Network. This paper describes our approach to distributed model and schema management and an architecture for facilitating the use of formal artificial intelligence concepts in application development with XML.

In recent years, the waterway navigation and transportation industry has been developing rapidly, living environment of ship cabins not received much attention. Using questionnaire surveys, data collection computer simulations, this study explored problems causes related to thermal comfort that affect a crew onboard. The survey showed differences in sensations crew. Cabins below deck are usuall...

Ship lock as a typical hydraulic structure has become an important node in waterway transportation. Due to the long operating life and high demand of throughput, many locks are under overloaded operation situation. However, service condition assessment ship rarely been directly studied, there is lack efficient standardized method owing complex system. In this paper, multi-level hierarchical sys...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
