Digital exchange of design models between marine equipment libraries using hybrid neutral formats

The selection of marine equipment is a time-consuming process for a ship outfitting designer. The inefficiency originates from the paper-based exchange of design information between shipyards and equipment manufacturers. We propose a method to exchange equipment models for electronic commerce. Shipyard practices were investigated to find out how the outfitting CAD library is being used. We also surveyed international standards for the exchange of digital equipment models, and analyzed the macroparametric methodology. We propose a hybrid method to represent the geometric information using STEP AP203 or the macroparametric method. The nongeometric information is defined according to the Parts Library (PLIB) standard. We implement a pilot system and test it with a ship design data set. The equipment model proposed can be used in the design process with heterogeneous shipbuilding CAD systems. The equipment model can improve the design and purchase process in shipyards.     

基于数据融合的公交客流规模测算方法

公交客流规模测算往往存在调查成本受限和准确度要求较高的矛盾.提出基于公交IC卡历史数据与人工补充调查数据的数据融合测算方法,以准确推算公交客流规模.首先根据公交线路的基本属性,采用聚类分析方法划分线路类型,从每一类中选择具有代表性的线路.基于IC卡数据分析公交客流时变特征,运用有序样本聚类Fisher算法将线路小时刷卡量进行聚类分析.划分刷卡量相似时段,进而采用优化方法确定调查抽样率,确定相应的调查车辆进行人工补充调查,最终经过数据融合计算获得公交客流规模.基于上海市某辖区IC卡数据进行案例分析,测算得到三类公交线路的日均客流量.     

Pushing the CZMA Envelope: California: The First State to Litigate the New Federal Law

As noted often by the former California Coastal Commission Executive Director Peter Douglas, the history of how the California coast was saved is a great repository of untold stories. Although the Commission has had a dramatic and tangible impact on California's coastal geography, the public is largely unaware of many of its early accomplishments. This article begins to chronicle the rich stories of California's coastal legacy by telling the story of how the Commission utilized the Coastal Zone Management Act (CZMA) to prevent Southern Pacific Railroad from developing a seven-mile stretch of the Monterey Bay shoreline. In so doing, the Commission helped make possible the creation of the Monterey Peninsula Recreational Trail, a public bicycle and pedestrian path that has grown to sixteen miles in length and runs through the heart of John Steinbeck's world-famous Cannery Row. The controversy also was the subject of the first judicial challenge of a state's federal authority under the CZMA and precluded private commercial and residential development that would have dramatically altered the urban form of the Monterey Peninsula. It is important to tell the story as the Coastal Commission's role in this remarkable accomplishment has been almost completely overlooked.

Public Perception of Ocean Governance and Marine Resources Management in Taiwan

Understanding public perception of the oceans, and relationship between society and the sea is an important key to the sustainable management of marine resources. This research reports the first population-based survey on Taiwanese public knowledge, attitudes, and actions on marine-related issues. The stratified random sampling by county was completed with 1,120 telephone respondents from October to December 2010. More than 60% of the respondents have heard about global warming, sea-level rising, the Gulf of Mexico oil spill, the coral reef bleaching crisis, and Japan whaling fisheries. However, less than 20% of the respondents are aware of Taiwanese domestic marine policies, such as the Ocean White Paper. On resources conservation, 74.7% of the respondents support the bluefin tuna catches regulations and 76.6% agree that the shark fin fisheries will impact shark resources. Education and age are the major affecting variables for resource conservation and knowledge. Higher education and age 40–49 are most supportive of conservation measures. For marine recreational activities, 42.2% of the respondents can swim, and 44.2% of the respondents had not visited the beach in the previous year. The results suggest that the government could establish a specialized agency to strengthen its marine policy and take more actions to protect ocean environment and conserve marine resources. To encourage more Taiwanese to participate in ocean recreational activities, the government could build a safe facility for marine recreation, cooperate with the private sectors in education, and provide outreach to raise public awareness of the oceans.     

The Offshore Wind Power Debate: Views from Cape Cod

Wind power resources on the eastern U.S. continental shelf are estimated to be over 400 GW, several times the electricity used by U.S. eastern coastal states. The first U.S. developer proposes to build 130 large (40 story tall) wind turbines in Nantucket Sound, just outside Massachusetts state waters. These would provide 420 MW at market prices, enough electricity for most of Cape Cod. The project is opposed by a vigorous and well-financed coalition. Polling shows local public opinion on the project almost equally divided. This article draws on semistructured interviews with residents of Cape Cod to analyze values, beliefs, and logic of supporters and opponents. For example, one value found to lead to opposition is that the ocean is a special place that should be kept natural and free of human intrusion. One line of argument found to lead to support is: The war in Iraq is problematic, this war is “really” over petroleum, Cape Cod generates electricity from oil, therefore, the wind project would improve U.S. security. Based on analysis of the values and reasoning behind our interview data, we identify four issues that are relevant but not currently part of the debate.
