    摘要： A process for separating a feed gas mixture into a more strongly adsorbable component and a less strongly adsorbable component in a plurality of adsorbent beds containing an adsorbent selective for the more strongly adsorbable component using pressurization by product end to product end pressure equalization between beds simultaneous with cocurrent ambient and elevated pressure feed pressurization, coproduction of product and purge gas, and cocurrent depressurization for pressure equalization gas simultaneous with countercurrent evacuation. Oxygen product can be recovered from air at high recovery using the process.

    摘要： A tree structure has a node associated with each category of a hierarchy of item categories. Child nodes of the tree are associated with sub-categories of the categories associated with parent nodes. Training data including received queries and indicators of a selected item category for each received query is combined with the tree structure by associating each query with the node corresponding to the selected category of the query. When a query is received, a classifier is applied to the nodes to generate a probability that the query is intended to match an item of the category associated with the node. The classifier is applied until the probability is below a threshold. One or more categories associated with the nodes that are closest to the intent of the received query are selected and indicators of items of those categories that match the received query are output.

    摘要： Methods, computer-readable storage media, and systems are provided to facilitate visually distinguishing common attributes of users an electronic communication network or messaging service. In particular, user profile attributes are compared between a first and second user, and similar attributes are visually highlighted by assigning, for example, a distinct font, font size, color, font effect, and/or other visual effect to the user's screen name to designate which attributes are similar. In addition, or alternatively, when the first user views a user profile of the second user, common user attributes are visually highlighted. In one embodiment, the font, font size, color, and/or font effect assigned to the highlighted attribute indicates a degree of similarity of the attribute. Such implementations may allow users to more easily recognize and interact with others that have similar interests and attributes.

    摘要： An implementation wherein RFID data is shared across independent organizations has been addressed. RFID data is usually spread across different parties, e.g. enterprises in a supply chain and thus, efficient query processing across all parties is required. Traceability is emerging as one of the key applications of RFID technology. A generic data model is introduced for querying RFID data across a network of independently operated data sources. The model can be used to facilitate traceability query processing and give a set of representative traceability queries. A newly designed process-and-forward approach is implemented for executing traceability queries.

    摘要： As provided herein objects from a source catalog, such as a provider's catalog, can be added to a target catalog, such as an enterprise master catalog, in a scalable manner utilizing catalog taxonomies. A baseline classifier determines probabilities for source objects to target catalog classes. Source objects can be assigned to those classes with probabilities that meet a desired threshold and meet a desired rate. A classification cost for target classes can be determined for respective unassigned source objects, which can comprise determining an assignment cost and separation cost for the source objects for respective desired target classes. The separation and assignment costs can be combined to determine the classification cost, and the unassigned source objects can be assigned to those classes having a desired classification cost.

    摘要： A system, a method and computer-readable media for identifying and presenting potential query refinements for a user's search input. Documents are identified as being responsive to the search input. A query log is accessed to identify previously entered queries that also returned one or more of the identified documents. From these previously entered queries, a portion of the queries are selected as potential query refinements. Thereafter, the potential query refinements are displayed to the user.
