Abstract:
Techniques are disclosed for calculating performance metrics associated with a data stream. A processing element configured to process data tuples flowing through a stream-based computing system receives data tuples via the data stream. Each of the one or more tuples is processed at the processing element, and each of the one or more tuples are associated with metadata that includes information related to the processing of the tuple by the processing element. Performance metrics are then calculated for the data stream based on the metadata associated with the one or more tuples.
Abstract:
Techniques are disclosed for invalidating, at one or more processing elements, data streams containing data tuples. A plurality of tuples is received via a data stream, whereupon the data stream is determined to be invalid based on at least one tuple in the plurality of tuples. The data stream is then invalidated, and a message is issued that causes one or more data streams included in the stream-based computing system and related to the invalidated data stream to also be invalidated.
Abstract:
A microdevice assembly (20) that includes a device microstructure (22), a housing (30), and a fine grain getter layer (40). The housing (30) has a base portion (32) and a lid (34). The device microstructure (22) is attached to the base portion (32) and the lid (34) is hermetically sealed to the base portion (32). The housing (30) defines a cavity (38) surrounding the device microstructure (22). The fine grain getter layer (40) is on an interior side (42) of the lid (34) for maintaining a vacuum in the cavity (38) surrounding the device microstructure (22). The lid (34) may be made of metal or have at least a metallic surface in the region where the fine grain getter layer (40) is applied. The fine grain getter layer (40) has a sub-micron grain size. There is also a method for making the microdevice assembly (20).

Abstract:
A vent assembly (50) for an electronic control module (28) is provided. The vent assembly (50) may be adheringly coupled to a printed circuit board (38). The vent assembly (50) being adapted to prevent the ingress of moisture and permit the egress of certain gases.
Abstract:
A database application re-uses one or more query execution strategies for a given logical query, and saves historical data concerning query execution performance under differing execution parameters. The historical data is analyzed to identify environmental variables and/or imported variables which significantly affect execution performance. Preferably, an auxiliary data structure includes, for each of multiple execution strategies, a respective set of imported and environmental variables and respective average cost measure, such as execution time. An analytical tool compares multiple different strategies to identify imported and/or environmental variables which caused a different strategy to be used, and resultant average cost. Preferably, the tool can also compare variation within the same strategy.
