Abstract: A process is provided for the determination of oil dispersant effectiveness. A submersible dispersant sensing platform is passed across a body of water. The platform has a plurality of sensors including a multichannel fluorometer and a particle size analyser, and each sensor produces an output data stream. The body of water is continuously analysed at a predetermined depth profile below the surface of the body of water. Hydrodynamic and environmental condition data is collected proximate in time and location to the output data from the dispersant sensing platform. The environmental condition data includes one or more of ambient temperature, body or water temperature, salinity of the body of water, wind speed, location, mixing energy of the body of water and derivatives thereof. Oil and dispersant data is provided which includes characteristics of the dispersant and of oil samples prior to the application of the dispersant.

Abstract: A blade sharpening device comprises a clamp for holding a blade in a fixed position relative to the device, an elongate slide member having a lower end adapted for sliding movement on a flat surface and an elongate support arm having a first end mechanically connected to the slide member. The elongate support arm extends at a fixed angle relative to the slide member and has a second end with the clamp provided thereon.

Abstract: Methods and apparatus, including computer program products, for block compression of tables with repeated values. In general, value identifiers representing a compressed column of data may be sorted to render repeated values contiguous, and block dictionaries may be generated. A block dictionary may be generated for each block of value identifiers. Each block dictionary may include a list of block identifiers, where each block identifier is associated with a value identifier and there is a block identifier for each unique value in a block. Blocks may have standard sizes and block dictionaries may be reused for multiple blocks.

Abstract: Methods for accurately and efficiently estimating a disinfestation rate of disinfestation equipment and making adjustments based on the estimated disinfestation rate to achieve a desired disinfestation rate are provided. In one example, a disinfestation rate may be based on a number of infested products in an untreated sample out of a total number of products in the untreated sample and based on a number of infested products in a treated sample out of a total number of products in the treated sample.

Abstract: Methods and apparatus, including computer program products, for compression of tables based on occurrence of values. In general, a number representing an amount of occurrences of a frequently occurring value in a group of adjacent rows of a column is generated, a vector representing whether the frequently occurring value exists in a row of the column is generated, and the number and the vector are stored to enable searches of the data represented by the number and the vector. The vector may omit a portion representing the group of adjacent rows. The values may be dictionary-based compression values representing business data such as business objects. The compression may be performed in-memory, in parallel, to improve memory utilization, network bandwidth consumption, and processing performance.

Abstract: Methods and apparatus, including computer program products, for selection of rows and values from indexes with updates. In general, rows of an index may be associated with validity flags that indicate whether a row has been updated with an update inserted in a delta index; one scheme for value identifiers may be used for an index and another scheme for one or more delta indexes where all of the indexes are, to at least some extent, compressed according to dictionary-based compression; and multiple delta indexes may be used in alternation such that one delta index may accept updates while another is being updated. The delta indexes may also have validity flags and all updates, such as modifications of values, deletion of records, and inserting of new records may be handled as updates accepted by one or more delta indexes.

Abstract: A turbo charger for an internal combustion engine includes a turbo charger housing defining a spool axis and including an exhaust chamber having an exhaust inlet and an exhaust outlet. The turbo charger housing also defines an air compressor chamber having an air inlet and an air outlet. A spool is mounted within the turbo charger housing for rotation about the spool axis. The spool includes a spool shaft with an exhaust turbine wheel mounted at one end and an air compressor wheel coaxially mounted for common rotation at the opposite end of the spool shaft. A compressed gas injector is mounted to the exhaust chamber of the turbo charger housing for providing a compressed gas flow to the exhaust turbine wheel from a source external to the turbo charger housing in order to supplement power from the exhaust to rotate the spool.

Abstract: A broadband data communications network includes mobile wireless communications devices, base stations, and a master access gateway for operating using a full data set for controlling broadband data communications between the base stations and the mobile wireless communications devices. A back-up gateway is coupled to a given one of the base stations for communicating with the master access gateway for generating a data subset from the full data set for the given base station and associated mobile wireless communications devices when communications between the given base station and the master access gateway is available. When communications is unavailable, then the back-up gateway operates using the data subset for controlling broadband data communications between the given base station and associated mobile wireless communications devices.
