    • A prognostic and health accuracy maintenance system and method for a system following on-site replacement of a component in the system is provided. A system characterization model of at least portions of the system is generated and embedded within a controller in the system. The system characterization model is adapted to receive a plurality of signals that are each representative of an operational parameter within the system and is responsive to each of the signals to generate simulation response data and determine system health based, at least in part, on the simulation response data. When a component within the system is replaced, a determination is made as to whether the replacement component exhibits one or more operational performance characteristics that differ from the component it replaced. If so, the embedded system characterization model is updated in-situ.
    • 提供了一种用于系统中现场更换组件的系统的预测和健康精度维护系统和方法。 系统的至少部分的系统表征模型被生成并嵌入到系统中的控制器内。 系统表征模型适于接收多个信号,每个信号各自代表系统内的操作参数,并且响应于每个信号以产生模拟响应数据并且至少部分地基于模拟来确定系统健康性 响应数据。 当系统中的组件被替换时,确定替换组件是否表现出与其替换的组件不同的一个或多个操作性能特征。 如果是这样,嵌入式系统特征模型就是现场更新。

    • A semiconducting internal boundary layer ceramic composition having a fine grain structure suitable for use in thin-layer multilayer capacitors is made in one step by firing a mixture comprising a major amount of finely divided strontium titanate, a minor amount of a compound containing either strontium or titanium, or an element functionally equivalent thereto, a minor amount of a semiconductor forming ingredient (dopant), the identity of which depends on whether the mixture is rich in strontium or in titanium, and a minor amount of a counterdopant selected from cuprous oxide or silver oxide. When the mixture is rich in titanium, the chemical doping agent used to produce semiconductivity is an oxide of a trivalent metal selected from bismuth, boron, iron, antimony, lanthanum and the rare earth and transition metals. When the mixture is rich in strontium, the dopant is an oxide of a pentavalent or hexavalent metal selected from tungsten (+6), niobium (+5), tantalum (+5), and molybdenum (+6).
