高校应该加强诚信教育与信用意识教育

近几年在某些高等学校发生了许多不守信用的事件，影响了高校的形象．因此，高校应重视信用建设，强化诚信教育和信用建设．     

海员避碰行动各指标相关性的多元回归分析

在获取大量海员避碰行动样本的基础上，通过建立多元线性回归的数学模型，分析了转向时机、转向幅度、目标船舷角、会遇两船的船速比等4个指标与目标船最后通过距离之间的相关性大小，结论对海员避碰行动决策有一定的参考价值。由于样本是在对海员进行航海模拟器训练中获得的，从而说明了用航海模拟器来研究避碰行为的可行性以及STCW公约强化模拟器训练的必要性。

Finite-difference simulation of green water impact on fixed and moving bodies

A numerical method was developed to predict the water impact pressure caused by green water phenomena. The density function method was employed in the framework of a locally refined overlapping grid system. The simple problem of a rectangular body placed in regular waves was considered and the simulation results were compared with tank experiments. Good agreement with experiment was shown for wave–body interactions and for the pressure values at three different positions on the body. The case of a rectangular body with a vertical wall on the deck was also considered and the comparison showed satisfactory agreement. It was demonstrated that this method could be extended to a moving body problem, in which the body was free to undergo heave, pitch, and surge motions.

Estimation of value of travel time reliability

In mode choice decision, travelers consider not only travel time but also reliability of its modes. In this paper, reliability was expressed in terms of standard deviation and maximum delay that were measured based on triangular distribution. In order to estimate value of time and value of reliability, the Multinomial and Nested Logit models were used. The analysis results revealed that reliability is an important factor affecting mode choice decisions. Elasticity is used to estimate the impacts of the different policies and system improvements for water transportation mode. Among these policies, decision maker can assess and select the best alternative by doing the benefit and cost analysis based on a new market share, the value of time, and the value of reliability. Finally, a set of promising policies and system improvement of the water transportation were proposed.
