Intelligent Data Pre-processing Model in Integrated Ocean Observing Network System

There are a number of dirty data in observation data set derived from integrated ocean observing network system.Thus,the data must be carefully and reasonably processed before they are used for forecasting or analysis.This paper proposes a data pre-processing model based on intelligent algorithms.Firstly,we introduce the integrated network platform of ocean observation.Next,the pre-processing model of data is presented,and an intelligent cleaning model of data is proposed.Based on fuzzy clustering,the Kohon...

Takagi - Sugeno Fuzzy PID Gain - Scheduling Controllers

This paper aims at Takagi - Sugeno (TS) fuzzy controllers as gain scheduling (GS) schemes of PID controllers. A TS fuzzy controller employs arbitrary input fuzzy sets, product or Zadeh fuzzy logic AND, TS fuzzy rules with linear consequent, and the generalized defuzzifler containing the popular centrold defuzzifler as a special case. We first establish the relationship between the TS fuzzy controller and the linear PID controller. The TS ftizzy controller is accurately a nonlinear PID controller with gains continuously changing with Its process output. Then we point out that the TS fuzzy controller is closely related to the traditional gain scheduler. The gains of the TS ftizzy controller are determined by three two - Input - one - output fuzzy systems with singleton output fuzzy sets. Finally, as a demonstration, a simple TS fuzzy controller employing two linear input fuzzy sets, Zadeh fuzzy logic AND, and the popular centrold defuzzifler is designed to be the gain scheduler for the PID controller.

高分子改性絮凝剂在船舶压载水有害生物治理中的应用

以农业废弃物玉米芯粉为原材料,用自制的阳离子醚化剂N-(2、3-环氧丙基)三甲基氯化铵对其进行阳离子化改性,以制备高分子改性絮凝剂.红外光谱扫描图谱显示,产物是含有季胺基团的胺基化纤维素和淀粉.用其絮凝沉淀处理船舶压载水中微藻,总体絮凝沉淀效果良好,用量为50 mg/L时,作用48 h后对新月菱形藻的去除率达到95%;作用72 h对小球藻达到同样的处理效果.同时,对添加絮凝剂前后上述两种藻的叶绿素a测定结果进一步表明,该絮凝剂对其有杀灭抑制作用.     

Surface Deformation with Multi-constraints Based on the Minimum Energy

A method for deformation of 3D point clouds models was proposed with multi-constraints including arc-length constraints and multi-points position constraints. The energy function was built for the polyline which had been converted from the curve. Based on the minimum energy curve method. the curve on the mesh was deformed. The test results show that the proposed method has good performance. Compared with the other method. shape preserving of the curve is better. Finally. this method is used for the deformation of the 3D mannequin model. Circumference changes of the mannequin model can be reflected by the arc-length change in the size of the cross section.     

一种基于生理双向调节机制的协同进化算法

为了提高多参数寻优效果,基于人体生理双向协同网络调节机制,提出一种网络协同优化算法(NCEA).对应相应生理系统设计其体系结构,具体包括监控管理级、协同调节级和群体搜索级:监控管理级根据适应度和群体分布密度等信息,发送协同指令给协同调节级;协同调节级根据协同调节指令,基于生理调节规律实时调整各个搜索群体的交叉和变异概率因子和搜索群体之间的个体交换概率,以及辅助群体的个体均匀化;群体搜索级包括主搜索群体和辅助群体,其中辅助群体为主群体提供优良个体,并避免搜索陷入局部最优.最后采用两个典型的多维非线性函数,检验NCEA的搜索精度和收敛速度,并应用于一种非线性智能优化控制器.试验结果表明,与标准的遗传算法和一种改进的遗传算法相比,NCEA具有较快的收敛速度和搜索精度.
