    摘要: A method and system for optimizing resource usage in an information retrieval system. Meta information in query results describes data items identified by identifiers. A chunk of the identifiers and a set of meta information are loaded into a first cache and a second cache, respectively. A portion of the set of meta information is being viewed by a user. The portion describes a data item identified by an identifier included in the chunk and in a sub-chunk of identifiers that identifies data items described by the set of meta information. If a position of the identifier in the sub-chunk satisfies a first criterion, then a second set of meta information is preloaded into the second cache. If a position of the identifier in the chunk satisfies a second criterion, then a second chunk of the identifiers is preloaded into the first cache.

    摘要: A breadcrumb method, system and computer program product for a website. In response to a request for visiting the website, a breadcrumb root node is generated in a tree structure. In response to receiving a request for visiting a first web task associated with the website, a first task node is generated in the tree structure at the breadcrumb root node. In response to sequentially receiving requests for multiple subtasks of the first web task, multiple subtask nodes of the first task node are sequentially established in the tree structure. The subtask nodes of the multiple subtask nodes of the first task node are sequentially connected to the first task node according to a sequential order of the sequentially received requests for the multiple subtasks of the first web task. The multiple subtask nodes of the first task node are processed based a policy of the first web task.

    摘要: A memory control unit of a turbo code decoder includes a buffer having a plurality of storage slots, a buffer control operatively coupled to the buffer, a router operatively coupled to the buffer control and to a plurality of data sources, and a conflict detection unit operatively coupled to the router, to the buffer control, and to the plurality of data sources. The buffer temporarily stores information intended for storage in a memory bank. The buffer control determines a number of available storage slots in the buffer. The router routes data from the data sources to the buffer control. The conflict detection unit initiates a temporary halt of some of the data sources when the number of available storage slots is insufficient to store all of the data from data sources attempting to access the memory bank.

    摘要: A lamp control system includes a first driving circuit, an assistance DC power source having an output voltage lower than a working voltage of a lamp and a second driving circuit. The first driving circuit electrically connects the lamp with a utility power source to convert an AC power a DC power and supply the DC power to the lamp. The second driving circuit electrically connects the assistance DC power source with the lamp. The second driving circuit includes a boost circuit, which is connected to the assistance DC power source to promote the output voltage of the assistance DC power source to the working voltage of the lamp and then supply electrical power with the promoted voltage to the lamp when the utility power source is off.

    摘要: An apparatus for trellis-based detection in a communication system including a processor and memory having computer program code configured to construct a trellis representing a transmitted signal formed from a plurality of symbols, each having a constellation size, transmitted by a number of transmit antennas, and form a log likelihood ratio at nodes of the trellis as a log-sum of a number of exponential terms corresponding to a hypothesized transmitted bit value of the plurality of symbols. The number of exponential terms is limited by a number of most likely paths of the trellis extending from each node of the trellis and the constellation size. The processor and memory including computer program code are further configured to form a list at each node of the trellis of a size limited to the number of the most likely paths of the trellis extending from each node of the trellis.
