摘要： A system and method for estimating a metric of a proposed product from a document describing the product in an arbitrary degree of detail provides accuracy comparable to a function point assessment of a fully detailed document by parsing a document into a plurality of lines in an outline form and assigning a hierarchy to each line. Values or weights are determined for each of a relatively small plurality of key words in accordance with the key word and the hierarchy level of the line in the parsed document in which the key word is found. An adjustment is made based on a category of the key word such as nouns and verbs and the hierarchy level of the lines as compared with the number of hierarchy levels found in the document. Further adjustments may be made for subject matter domain of the product and the source or author of the document.

摘要： A method for providing a real time measurement of the purity of one gas in a binary mixture of two known gases, which mixture also contains water vapor, applies principles of the fan laws and ideal gas laws in a manner whereby the volume percent purity of the gas may be calculated directly from measured fan differential pressure. The calculted purity is preferably corrected for variations in temperature and pressure. The method requires the determination and use of an appropriate fan constant based on the gas whose purity is to be measured and specific to the fan being used to circulate the gas mixture and the speed at which it operates. An appropriate adjustment factor for differences between design and measured speed may also be applied in acordance with the fan laws. The method is particularly well adapted to provide real time measurement of hydrogen gas purity in the cooling gas circulated inside a large synchronous AC generator and utilizing a microprocessor to provide a real time output of hydrogen gas purity. The principles underlying the method of the invention are also utilized to develop a correction factor to convert hydrogen purity measured from a dry gas mixture sample using a thermal gas analyzer to a true hydrogen purity. The method may further to applied to calculate actual water vapor content in a sample from which hydrogen purity was measured by a thermal gas analyzer.
