基于图像处理的桥墩防撞预警系统的研究

利用图像处理硬件设备，通过摄像头将视频信息采入，送入DSP进行分析处理；专门视频信息处理软件，运用各种图像处理技术，进行实时处理分析，对船舶进行实时监控。当船舶进入预警区，经计算机判断处理，提醒监控人员并通过广播对船舶驾驶人员发出警告，避免事故发生。 在图像序列处理技术的开发中，采用软硬件分离的方法，先进行基于Visual C＋＋的计算机软件设计研究；在软件中，研究了船舶检测、船舶跟踪与计算等内容。

Turbo编解码结构及基于LOG-MAP算法的性能仿真研究

阐述Turbo码的编解码结构。研究MAP以及LOG MAP解码算法。设计MATLAB仿真运算程序。根据设计的仿真程序比较Turbo码在不同约束长度、不同迭代次数以及不同编码速率情况下的性能。由仿真结果得出影响Turbo码性能的主要因素是交织器长度、迭代次数、编码速率。在各种情况下通过增加交织器长度和迭代次数、降低编码速率来改善Turbo码的性能。

The Nigerian shipping industry and indigenous shipping companies

The shipping industry in Nigeria since the early 1990s has been experiencing a continuous disastrous downturn. Nigerian shipping companies' participation in international shipping has continued to be very limited. Their presence and impact is hardly felt in the world's shipping industry. Both the national carriers (that is shipping companies with national carrier status) and other indigenous private shipping companies have vessel as well as management problems. These problems have led to the poor performance of the Nigerian shipping industry for over a decade now. The carriers in the industry are not attaining for the country the gains that are supposed to emanate from shipping. This paper points out the importance of shipping to a nation, identifies the problems the country's shipping companies are facing and proffers solutions that include merging of the companies to have strong financial standing and a competitive edge.     

利用RBF神经网络预测和消弱低频无线电导航定位误差

由于诸多因素的影响，导致了低频无线电导航系统的定位误差和GPS卫星导航系统的定位误差之间存在较大的差距，拟采用径向基函数（RBF）网络来预测电波传播误差，以期达到修正现有低频无线电导航系统定位误差的目的，从而进一步提高低频无线电导航定位的精度。     

儿童慢型克山病的自然病程

为了探讨儿童慢型克山病的自然病程和预后危险因素，本文分析了长期随访的儿童慢型克山病６３例，结果表明：①儿童慢型克山病预后差，其１年存活率５０．５％、５年仅１５．８％；②自然慢性发病、有奔马律、心功能Ⅲ级以上，心电图心室增大，Ｘ线心胸比率重度扩大者，５年存活率低（Ｐ＜０．０５或０．０１）。     

Intra-Platoon Collision Behavior during Emergency Operations

This paper presents current research regarding intra-platoon collision dynamics for rapid decelerations. Measures of ride quality and impact severity are introduced to allow comparisons between different collision scenarios. In this study, the disturbance input to the platoon is assumed to be a rapid braking of the lead vehicle. Several deceleration rates are used to assess the overall platoon behavior and the effect of the intra-platoon collisions on the platoon passengers. The role of the desired headway spacing on preventing the occurrence of intra-platoon collisions and improving rider comfort is discussed.
