摘要:
A method for determining a maintenance schedule of geographically dispersed physical assets includes receiving asset data including infrastructure relationships between the assets, modeling failure risk of the assets based on spatial, temporal and network relationships, and producing the maintenance schedule according to a combination of the risk model, asset data, maintenance, and external operation constraints. The maintenance schedule may be corrective and/or strategic.

A method and an apparatus for determining leakage volume of fluid in transportation pipelines are provided. The method comprises: obtaining the negative pressure wave signals detected by at least two pressure sensors arranged on the pipeline; determining the pressure signal at the leakage location based on the negative pressure wave signals; determining the leakage rate during a leakage period based on the pressure signal at the leakage location according to a leakage model; and determining the leakage volume of the fluid in the pipeline based on the leakage rate and the leakage period. The apparatus provided corresponds to the method described above. By using the method and apparatus described above, the leakage volume of the transportation pipelines can be obtained to help understand the leakage profile of the pipelines and thus reduce losses.

摘要:
A method for checking pipeline leakage comprises: receiving detecting parameters collected by at least one sensor with respect to pipelines in its corresponding region; gathering detecting parameters collected by the at least one sensor; analyzing the gathered detecting parameters to obtain an evolutionary tendency of detecting parameters in the corresponding region of the at least one sensor; judging if the evolutionary tendency of the detecting parameters satisfies predefined features of leakage; determining that pipeline leakage exists in the corresponding region if the evolutionary tendency of the detecting parameters satisfies the predefined features of leakage. The present invention may help to determine leak regions with a leakage having small flow quantity, and provide a user with regions with pipeline leakage to be detected based on a resource constraint.

An approach is provided for determining one or more recommendations based on an incremental update of a recommendation model. An incremental platform causes, at least in part, a categorization of activity information into a plurality of subsets based, at least in part, on one or more user groups, one or more item groups, at least one update time for at least one recommendation model associated with the activity information, or a combination thereof. The incremental platform further processes and/or facilitates a processing of the activity information based, at least in part, on the categorization to determine whether to perform an incremental update of the at least one recommendation model. The incremental platform also determines one or more recommendations based, at least in part, on the at least one recommendation model, the incremental update, or a combination thereof.

An approach is provided for creating a connection between users of a social network. The approach involves determining location information associated with a user and other location information associated with one or more other users. The approach also includes processing the location information and the other location information to cause, at least in part, identification of one or more encounters, one or more encounter patterns, or a combination thereof with respect to the user and the one or more other users. The approach further includes determining to generate at least one recommendation to create at least one social network, at least one social networking relationship, or a combination thereof between the user and at least one of the one or more other users based, at least in part, on the one or more encounters, the one or more encounter patterns, one or more meetings and/or events, or a combination thereof.
摘要:
Novel compounds of the structural formula I, and the pharmaceutically acceptable salts thereof, are inhibitors of TarO and may be useful in the prevention, treatment and suppression of diseases mediated by TarO, such as bacterial infections, including gram negative bacterial infections and gram positive bacterial infections such as MRSA and MRSE, alone or in combination with a β-lactam antibiotic.
摘要:
This invention disclosed condoms with surface hydrophilic and lubricious modification. Said condoms were grafted with a thin layer of zwitterions, which forms lubricious water layer when contacted with human body liquids or other water solutions, to lower the surface friction and mechanical damage to human body, and to improve user's experience. Another benefit of present invention is due to the tight bonding between modification material and condom substrate, the modification will stably stay on the substrate during usage, to avoid the potential side effects caused by lubricants.
