    摘要: An air-exhaust mixer assembly includes an air intake to supply air and an exhaust gas intake to supply exhaust gas. A mixer is fluidly coupled to the air intake and the exhaust gas intake. The mixer has an inner passage and an outer passage defined therein along a longitudinal axis. The inner passage and the outer passage are adapted to mix the air and the exhaust gas by expanding the air and the exhaust gas in radially opposite directions with respect to the longitudinal axis.

    摘要: A technique for analyzing test results obtained by applying a binary table and a suite of test scripts to a test subsystem control facility for a distributed systems network. The binary table expresses a proposed set of requirements for a proposed subsystem control facility. The suite of test scripts is prepared from a knowledgebase containing test generation information relating to a predetermined global set of subsystem requirements. The test results are compared with the knowledgebase containing the predetermined set of subsystem requirements, and the relative performance of the proposed set of requirements with the predetermined set of subsystem requirements is graphically displayed or printed. The predetermined set of subsystem requirements includes rules governing the operation of a subject network and a library of permitted commands and object types. The proposed set of requirements includes paired selections of commands and object types from the library. The test results obtained using at least some of the paired selections of commands and object types are compared with the corresponding predetermined set of subsystem requirements in the knowledgebase, and violations of the rules are specified. The library further includes object modifiers and attributes, and the proposed set of requirements further includes selected modifiers and attributes paired to objects. The nature of any non-conformance of the proposed set of requirements to the predetermined set of subsystem requirements is indicated, along with the correction required to establish conformance. Any non-conformance is also related expressly to the predetermined set of subsystem requirements.

    摘要: A method and system for preparing a suite of test scripts for testing a proposed network management application. The proposed network management application, termed a subsystem control facility (SCF), is first defined as a set of requirements with the aid of a developmental tool incorporating a subsystem knowledgebase and a test generation knowledgebase. The subsystem knowledgebase contains the rules governing the operation of a given network and a library of permitted commands, objects, attributes, modifiers and other data. The test generation knowledgebase includes information relating to those commands and objects specific to the proposed subsystem control facility set of requirements. A user interface coupled to the knowledgebases permits the selection of types of tests and specific commands and objects to be tested. Once test selection has been specified, test scripts corresponding to the selected tests are generated from the first and second knowledgebases for use in testing the proposed set of requirements for the SCF prior to coding the SCF. The suite of test scripts can be used to test the proposed SCF set of requirements, detect nonconformance with the rules and permit modification of the proposed set of SCF requirements. If necessary, additional testing may be performed using the same test scripts or a subset thereof, until the test results indicate no errors and a minimum number of warnings. Thereafter, the SCF product module can be coded. Errors in the developmental stage can be thus corrected early in the developmental cycle.
