摘要： Systems and methods are provided for file searching on mobile devices. A system includes a user interface and a file query system. The user interface is for receiving a user-provided spatio-temporal query for use in searching for a particular file. The user-provided spatio-temporal query is provided by a user of a mobile device. The file query system is for determining information about the particular file responsive to the user-provided spatio-temporal query, and identifying from the information one or more files as a search result for the particular file.

摘要： Systems and methods provide a selective instrumentation strategy for monitoring the progress of transactions in a distributed computing system. The monitoring of the transactive processing of jobs is considered through a collection of computer operating stages in a distributed system, using limited information. The monitoring is performed by observing log records (or footprints) produced during each stage of processing in the system. The footprints lack unique transaction identifiers resulting in uncertainties in monitoring transaction instances. The processing stages are selective instrumented to reduce monitoring uncertainty under the given constraints such as limited budget for instrumentation cost.

摘要： A method for measuring trust in a transaction over a public key certificate network includes associating each edge KA→KB of an public key certificate network connecting two public keys KA and KB with a probability p that information about KB is reliable, and a confidence c that is a total dollar amount of transactions which have involved using edge KA→KB. One or more authentication paths are formed in the public key certificate network starting from public key KS and ending with a target public key KT. A limit l of an amount of insurance that an owner of KS is willing to provide to a user interested in a transaction with an owner of KT is calculated, and for each amount m

摘要： Orthogonal Frequency Division Multiplexing (OFDM) is combined with a plurality of transmitting antennas to yield a system that provides space, frequency and time diversity. Specifically, an arrangement is created where a transmitter includes a plurality of antennas that are transmitting simultaneously over the same frequency subbands, and the symbols that are transmitted over each subband, in any given time slot, over the different antennas are encoded to provide diversity. The principles of trellis coding, space-time coding, or any other diversity-producing coding can be applied in this arrangement.
