Abstract: The present invention provides a system and method for automatically deriving unique surrogate response data from experiment results in which inherent data loss occurs in a sufficient number of the samples to disallow quantitative effects estimation at the experimenter's desired level of confidence for statistical significance. In part, the unique surrogate response data sets of the present invention have four primary characteristics including: each is numerically analyzable; each may be more readily or directly obtained in which inherent data loss occurs; each provides a response value for an experiment trial; and each provides information on the effect of the change made to the process or system that would have been obtainable if the experiment samples had had no inherent data loss.

Abstract: A system and method for computing a blind checksum includes a host Ethernet adapter (HEA) with a system for receiving a packet. The system determines whether or not the packet is in Internet protocol version four (IPv4). If the packet is not in IPv4, the system computes the checksum of the packet. If the packet is in IPv4, the system determines whether the packet is in transmission control protocol (TCP) or user datagram protocol (UDP). If the packet is not in either of TCP or UDP the system attaches a pseudo-header to the packet and computes the checksum of the packet based on the pseudo-header and the IPv4 standard.

Abstract: A method, computer readable medium, and system for optimizing a query in a relational database processing system is disclosed. The present invention relates to a query rewrite optimization method for eliminating a redundant join and equivalent subquery in an SQL query before generation and selection of the optimal query execution plan. The method of the present invention includes evaluating the query to identify a join predicate joining a sub-expression of the query to itself, and determining whether a row set producible from a first set of references of the query to the sub-expression is subsumed by a row set producible from a second set of references of the query to the sub-expression. Based on such evaluation and determination, the query may be reformed to eliminate the join predicate and the second quantifier. A further determination of the removability of the second quantifier may be required such as by evaluating a cardinality constraint when query output cardinality is material.
