摘要： A method to assess external corrosion in buried pipelines includes analysis of moisture content of soil along the length of the pipe to choose the most appropriate indirect inspection methods. External corrosion is assessed based on the unification of probability techniques using clustered inspection data and deterministic formulation for soil conditions. A deterministic model pinpoints the location of the most likely areas for corrosion due to the electrochemical cell formation produced by the presence of water and the properties of the soil, such as ion concentrations, pH, soil resistivity, redox potential, corrosion potential and soil type. The filtering of the data by clustering provides reliable results to locate the most corrosive locations. The failure probability is calculated based on in-line inspection data, where different indications could appear and different dimensions are used to link the corrosivity with the failure for choosing repairing methods and taking actions against corrosion.

摘要翻译：一种评估埋地管道外部腐蚀的方法，包括沿管道长度分析土壤含水量，选择最合适的间接检验方法。基于使用聚类检验数据的概率技术的统一性和土壤条件的确定性公式来评估外部腐蚀。确定性模型指出了由于水的存在和土壤的性质，如离子浓度，pH，土壤电阻率，氧化还原电位，腐蚀电位和土壤类型产生的电化学电池形成，最可能的腐蚀区域的位置。。通过聚类过滤数据提供了可靠的结果来定位最具腐蚀性的位置。故障概率是根据在线检验数据计算的，其中可能出现不同的指示，并使用不同的尺寸将腐蚀性与选择修理方法的故障和采取防腐措施联系起来。

摘要： Improved capacitors containing novel electrodes are described. One electrode composition comprises mixed metal oxides of the transition metals nickel and cobalt in a molar ratio of 0.5:1 or greater, and optionally containing a binder and carbon nanotubes. The resulting capacitors can be characterized by superior properties including higher specific capacitance values at higher voltage scan rates than the prior art. Methods of forming the electrodes that produce superior results are also described.
