谈澳大利亚压载水管理新的申报格式

凡到过澳大利亚港口的船员都有共同的感觉：水清、鱼跃。这是澳大利亚长期重视和保护生态环境的结果。为将海洋有害生物和船舶压载水病源体以及压载沉积物排放的风险降到最低限度，AQIS(Australian Quamatine and Inspection Service)在管理实践中几经推出修改，以IMO压载水管理指南(A．868(02)号决议)为基础，订立了新的压载水管理安排，并由2001年7月1日生效及强制实施。凡前往(或在)澳大利亚水域营运的船舶，其船东、船舶经理人和船长务必留意新规定并遵照规定行事，亦即必须以新的表格正确申报压载水管理；

Data Fusion Algorithm for Multi-Sensor Dynamic System Based on Interacting Multiple Model

This paper presents a data fusion algorithm for dynamic system with multi-sensor and uncertain system models. The algorithm is mainly based on Kalman filter and interacting multiple model(IMM). It processes crosscorrelated sensor noises by using augmented fusion before model interacting. And eigenvalue decomposition is utilized to reduce calculation complexity and implement parallel computing. In simulation part, the feasibility of the algorithm was tested and verified, and the relationship between sensor number and the estimation precision was studied. Results show that simply increasing the number of sensor cannot always improve the performance of the estimation. Type and number of sensors should be optimized in practical applications.
