prior processing
1.The general error handling treatment recommended for UDDI operators is to detect errors in a request prior to processing the request.
2.See appendix B for more information related to the use of byte order marks and UTF-8 and the way the UDDI SOAP implementations convert all requests to Unicode prior to processing.
3.Unicode UTF-8 allows data to be transmitted with an optional three-byte signature, also known as Byte Order Mark (BOM), preceding the XML data. This signature does not contain information that is useful for decoding the contents; but, in the case of UTF-8, tells the receiving program that the rest of the text is in UTF-8. Its presence makes no difference to the endianness of the byte stream as UTF-8 always has the same byte order. The BOM is not part of the textual content, and it is safe for Operator Sites to remove the BOM prior to processing messages received.
4.Bayesian network is a new pattern classification graph model based on Bayesian statistics, it is an intelligent tool that can integrate prior knowledge and sample information in classification and causality discrimination for data processing.
5.Coordinate any required CAE analysis (eg.Moldflow) to validate tool design and processing parameters prior to tool manufacture.
6.The problem of signal processing for direct-sequence code-division-multiple-access (DS-CDMA) signal over multipath frequency-selective mobile channels is considered.A new blind receiver is proposed.Without the knowledge of the multiple-access interference users′ spreading code and the channel characteristics,the receiver achieves blind detection with prior knowledge of only the desired users′ spreading code and approximate timing.By using reduced rank adaptive decorrelating filter and adaptive multipath combiner which is based on decision-directed algorithm,the receiver gets the ability to combat both fading and the near-far effect at low cost.Simulation results demonstrate that the proposed receiver offers high performance.
