An Analysis of the Impact of the Internet on Coastal Management

The role of the Internet in coastal management practice is analyzed through the Internet's communication and information access capacity. Primary and secondary impacts of the Internet in coastal management are assessed. A broad research framework is employed, including background on the development and spread of the Internet worldwide; analysis of emerging literature on the societal impact of the Internet; limited existing research on the use of the Internet by environmental management professionals generally and coastal managers in particular; and personal experience of the authors in the development of coastal management Internet sites. This analytical framework is supplemented by the first survey of integrated coastal management (ICM) Internet websites by www.coastalmanagement.com and a case study of the Internet Center for Coastal Management (ICCM) Internet-based communication platform based at the University of Washington. The survey of ICM websites found a total of 77 websites worldwide, with a dominance of sites in English located in the developed world. Assessment of the first year of operation of the ICCM project to facilitate discussion between coastal management practitioners and students in the United States and the Philippines demonstrates the enormous potential of the Internet as a communications tool in coastal management and also reveals the many practical technological and cultural constraints of using the Internet, especially in working on a project between the developed and developing world. Three groups of scenarios of the future use of the Internet in coastal management with decreasing levels of forecast certainty, namely, "probable," and "possible," and "potential for" are presented and discussed. Finally, the potential for the Internet to fundamentally transform the practice of coastal management is analyzed. It is concluded that while such a potential exists, there remain significant research questions requiring further analysis before the full transformative potential, and the possible impacts of such a transformation on coastal management, can be fully assessed. This article aims to provide a benchmark against which such future assessments can be made.     

Collaborative Management of Natural Resources in San Diego Bay

This article presents the results of a three-year effort at applying information technology to the problem of collaborative natural resource management in San Diego Bay. As such, it represents an approach to integrated coastal zone management (ICZM). This effort resulted from a collaboration between the San Diego Supercomputer Center at the University of California, San Diego and the San Diego Bay Interagency Water Quality Panel for the purpose of (1) developing an environmental data repository to facilitate the acquisition and sharing of data and (2) the development of a visual model of the bay in support of the development of a comprehensive, coordinated management plan for San Diego Bay. It was determined from this study that information technology is an important and key component to ICZM but that sociopolitical factors may override the benefits of decision-support systems and should be considered at the outset of any project of this kind.     

Attitudes toward Participation in Cooperative Coastal Management: Four European Case Studies

Findings are reported of the VALCOAST project that had as one of its research objectives to ascertain: (a) stakeholder willingness to participate and cooperate in coastal management (CM), given local and national CM practices; and (b) stakeholder assessment of the "accessibility" and "friendliness" of current CM processes. The project involved case studies and stakeholder interviews in Belgium, Greece, Spain, and the UK. Major findings include: (1) most stakeholders are willing to cooperate in three out of the four case areas, but not to the same extent; (2) the participating "officials" in the case studies are expecting the stakeholders to be less willing to cooperate than the latter indicate; (3) stakeholders in all case studies do not expect to be heard by those responsible for CM, find it difficult to learn about the relevant institutional arrangements, and consider the communication of the objectives and anticipated impacts of CM policies to be inadequate. It is concluded that the strong evidence of stakeholders' potential willingness to cooperate in local initiatives is very encouraging for a devolved, regional approach to European Union coastal management policies, provided that this potential is capitalized upon in such policy processes.     

基于自适应神经网络的UUV航速控制仿真研究

针对无人水下航行器(UUV)在水动力参数变化和外界不确定干扰下的航速控制问题,提出一种基于李雅普诺夫方法的自适应神经网络控制算法。引入RBF神经网络来估计建模误差和海流干扰,并设计自适应学习律来保证神经网络权值的最优估计,保证了系统的航速误差收敛到零。仿真试验结果表明设计的控制器在航速控制过程中可有效抑制UUV载体的模型不确定性及海流干扰,且控制参数易于调节。

内河集装箱班轮优先过闸管理模式探讨

文章结合2013年最新出台的《广西壮族自治区船闸管理办法》,以及近期国家关于行政审批制度改革的相关精神和要求,对集装箱班轮优先过闸条款进行探索和研究,分析了集装箱班轮优先过闸面临的主要问题,提出了一套新的市场管理模式,即主要采取企业公开"承诺制",加上"定期、定港、定线、不定船"的管理模式,通过实施"宽进严管",以期在简政放权的同时,能够充分发挥市场作用,促进企业自律,推动内河集装箱班轮运输市场的健康发展。     

汽车排气管设计中QFD与FMEA的集成应用研究

在汽车产品质量管理过程中,QFD和FMEA作为两个核心工具得到广泛应用,这两种工具的结合,既可以分析出最大限度的满足顾客需求的关键技术特性和质量特性,又可以将顾客需求与企业实际生产能力相结合,找出对产品质量影响较大的潜在的质量缺陷和失效模式,合理的调整相应的设计参数。本论文以汽车排气管设计为例,集成应用QFD与FMEA分析工具,从排气管产品的关键技术特性和关键零部件特性方面对产品进行了改善,对企业产品开发中的质量管理具有实际指导意义。
