Verifying liner Shipping Alliance’s stability by applying core theory

The core is a vital concept in cooperative game theory and has been widely used in analyzing alliance’s stability. It is especially interesting to apply core theory in liner shipping market due to the latter’s exceptional characteristic of non-homogeneous cost curves as well as divisible and fluctuant demand. Having observed some new phenomena and trends in the industry, this paper studies the economic performance and stability of liner shipping alliance by applying core theory where business cooperation is partly realized by delivering joint-service with mega container ships. To demonstrate the core situation in liner shipping alliance, a cost function is first identified on the basis of two assumptions regarding cooperation: 1) sharing or pooling vessels and 2) deploying mega container ships if needed. Taking cost functions as basis, two conditions of approaching core may be groomed, i.e., collective rationality and individual rationality. The first condition is discussed from the perspective of market, while the second condition is studied within the alliance. Stability of liner shipping alliance is then observed based on these two conditions. An illustrative case study is conducted in order to show some implications and explicitly clarify the theory.     

Boosting Chin Maritime Strategy

Authorized by the competent authority, CCS is the sole professional organization to carry out classification and statutory survey and notarial certification of ships and offshore oil and gas projects. CCS' rule and standard system for offshore installations has experienced 30 years, from none to possessing rules, from statutory and classification survey to competing for notarial certification, and from offshore to deep sea. In recent years, with the quickening of Chinese offshore oil and gas resources exploration, the rule and standard system of CCS has been strengthened and improved continuously.

圆电极电磁流量计干标定模型及仿真

目前在电磁流量计的干标定研究中，为方便公式推导，通常将实际的圆电极简化为方电极模型．这种简化在电极尺寸较大时，会引入不必要的计算误差，影响流量计的标定精度．本文从圆电极模型出发，论述了其对应权重函数的计算过程．并针对大尺寸圆电极模型进行理想化计算，得到其点电极模型，并运用此模型进行了仿真研究．     

无线技术在汽车电控系统中的应用

为了解决传统汽车中组合开关线束复杂、价格昂贵的问题,设计并搭建了一个基于无线局域网络的电气机构控制系统。选用车载电脑为人车交互窗口来完成人车对话,以新力维无线模块WM001S为载体实现无线控制信号与汽车CAN总线的连接,这样就实现了控制开关与汽车ECU的通信。再通过ECU来实现对电气机构的控制,从而达到了借助无线网络来控制汽车电气机构的目的。实验结果证明,该系统最大响应时间为200ms、操作简单、工作稳定可靠、大大降低了线束的复杂程度以及布置线束的空间要求。     

Color image segmentation by edge linking and region grouping

A novel method toward color image segmentation is proposed based on edge linking and region grouping. Firstly, the edges extracted by the Canny detector are linked to form regions. Each of the end points of edges is connected by a direct line to the nearest pixel on another edge segment within a sub-window. A new distance is defined based on the feature that the edge tends to preserve its original direction. By sampling the lines to the image, the image is over-segmented to labeled regions. Secondly, the labeled regions are grouped both locally and globally. A decision tree is constructed to decide the importance of properties that affect the merging procedure. Finally, the result is refined by user’s selection of regions that compose the desired object. Experiments show that the method can effectively segment the object and is much faster than the state-of-the-art color image segmentation methods.
