Ship Trajectory Control Optimization in Anti-collision Maneuvering

A lot of attention is being paid to ship’s intelligent anti‐collision by researchers. Several solutions have been introduced to find an optimum trajectory for ship, such as Game Theory, Genetic or Evolutionary Algorithms and so on. However, ship’s maneuverability should be taken into consideration before their real applications. Ship’s trajectory control in anti‐collision maneuvering is studied in this paper. At first, a simple linear ship maneuverability model is introduced to simulate its movement under different speed and rudder angle. After that, ship’s trajectory control is studied by considering the duration of rudder, operation distance to turning points, and maximum angular velocity. The details for algorithm design are also introduced. By giving some restrictions according to the requirements from COLREGs, the intervals for rudder angle in different circumstances can be determined based on the curves. The results can give very meaningful guidance for seafarers when making decisions.

Phase Behavior and Solubilization of Microemulsion System Formed by Aliphatic Polyethenoxy Ether and Sodium Dodecyl Sulfonate

Chen J. F., Gao Y. Ch., Li H. L., Chai J. L., Yang X. D., Qin C. K.

Polish Journal of Chemistry

Vol. 82, nr 5

The phase behavior and solubilization of the quaternary system AEO-9/AS/n- butanol /alkane/NaCl solution were investigated with delta-gamma and epsilon-beta fishlike phase diagrams. Two kinds of diagrams were plotted and compared in their shapes, HLB plane equations and solubilization power representations. Their HLB plane equations were used to calculate the composition of the hydrophile-lipophile balanced interfacial layer. It is found that the synergism between AEO-9 and AS in the inter facial layer in solubilization power exists. The influences of oil and aqueous medium on the epsilon-beta fishlike phase diagram were also discussed.
