Abstract: A method and information handling system (IHS) converts a globally unique identifier to an electronic data interchange document identifier. The method includes receiving a globally unique identifier and converting the globally unique identifier into 128 binary bits. The 128 binary bits are selectively separated to form groups of bits that translate to integers. Each integer is replaced with an assigned alphanumeric character selected from an alphanumeric character map to form an encoded alphanumeric string of characters for use as an electronic data interchange document identifier.

Abstract: Data compression using a combination of content independent data compression and content dependent data compression. In one aspect, a system for compressing data comprises: a processor, and a plurality of data compression encoders wherein at least one data encoder utilizes asymmetric data compression. The processor is configured to determine one or more parameters, attributes, or values of the data within at least a portion of a data block containing either video or audio data, to select one or more data compression encoders from the plurality of data compression encoders based upon the determined one or more parameters, attributes, or values of the data and a throughput of a communications channel, and to perform data compression with the selected one or more data compression encoders on at least the portion of the data block.

Abstract: Data to be stored in a data block for a columnar database table may be compressed according to a multi-level compression scheme. Data to be stored in the data block may be received. The data may be compressed according a column-specific compression technique to produce compressed data. The compressed data may then be compressed according to a second compression technique different than the column-specific compression technique to produce multi-level compressed data. The multi-level compressed data may be stored in the data block. When reading from the data block, multi-level compressed data may be decompressed according to the column-specific compression technique and the default compression technique applied to the data.

Abstract: A method is described for use in a satellite communication network, utilizing available resources (e.g. when operating in an idle mode) of at least one first terminal. that belongs to a cluster comprising a plurality of terminals that are adapted to communicate with a satellite, by at least one other terminal being a second terminal that belongs to that cluster of terminals, and wherein the utilization of idle resources is done by enabling communications between the first and second terminals is carried out by using a communication link that is not part of the satellite communication network.

Abstract: Decompressing sliding window compressed data requires reference to previously decompressed character sequences. Previously decompressed data is stored in a history buffer to satisfy these ‘back references.’ As each decompressed/decoded character is emitted, it is stored in this history buffer. Thus, for each decompressed character that is emitted, the history buffer may need to be accessed at least twice—once to retrieve the backreference, and once to store the emitted character. A pipeline architecture is disclosed that stores decompressed characters in a write queue that coalesces eight or more emitted characters before they are stored in the history buffer memory. This reduces collisions between accessing the history buffer memory to retrieve the backreferences and the storing of the emitted character. This also allows the use of a single-ported memory which is less expensive than a multi-ported memory.

Abstract: Aspects provide digital media content as a function of embedded environmental impact data. When a digital multimedia item is received, an embedded environmental impact value is decoded and the item is utilized as a function of the decoded embedded environmental impact value. Some aspects account for amounts and types of energy used in creating the item to calculate an environmental impact value for the item, and the calculated environmental impact value is embedded within digital data of the item.

Abstract: A coding method for data compression of a power spectra of an optoelectronic component and a decoding method are disclosed. In an embodiment, a coding method includes providing a power spectrum, sampling the power spectrum at particular sampling wavelengths in order to provide a discrete source spectrum, indexing the discrete source spectrum in order to provide a source graph having discrete source values, producing an image graph having discrete image values by transforming the source graph from a source range into an image range with a discrete frequency transform, performing compression of the image graph, and digitizing the compressed image graph in order to produce compressed spectral data.

Abstract: Techniques are provided for maintaining data persistently in one format, but making that data available to a database server in more than one format. For example, one of the formats in which the data is made available for query processing is based on the on-disk format, while another of the formats in which the data is made available for query processing is independent of the on-disk format. Data that is in the format that is independent of the disk format may be maintained exclusively in volatile memory to reduce the overhead associated with keeping the data in sync with the on-disk format copies of the data. Selection of data to be maintained in the volatile memory may be based on various factors. Once selected the data may also be compressed to save space in the volatile memory. The compression level may depend on one or more factors that are evaluated for the selected data. The factors for the selection and compression level of data may be periodically evaluated, and based on the evaluation, the selected data may be removed from the volatile memory or its compression level changed accordingly.

Abstract: In a compression processing storage system, using a pool of compression cores, the compression cores are assigned to process either compression operations, decompression operations, or decompression and compression operations, which are scheduled for processing. Only decompression operations are assigned to the plurality of compression cores having an idle status, where the idle status represents those of the plurality of compression cores that have yet to process any of the compression operations, decompression operations, and decompression and compression operations during a predetermined threshold period.

Abstract: Apparatuses, methods, systems, and program products are disclosed for managing storage of digital content. An eligibility module determines one or more content elements that are eligible for compression. A content element is determined to be eligible for compression based on one or more characteristics of the content element. A rate module determines a compression rate for each of the one or more content elements. The compression rate comprises an amount of compression to be applied to a content element. The amount of compression to be applied to the content element is determined as a function of one or more characteristics of the content element. A compression module compresses each of the one or more eligible content elements according to the determined compression rate.
