20130204892 | BIASING SEARCH RESULTS TOWARD TOPICS OF INTEREST USING EMBEDDED RELEVANCE LINKS - Redirection (“biasing”) architecture that automates the selection of topical terms in a search query, and provides a user-selectable (e.g., clickable) interface which enables the user to quickly and easily re-formulate and execute a new query using terms that return more focused search results. The redirection of search by biasing the terms (strings) can also be performed by indicating that certain results are not interesting to the user. For example, one way using an existing search engine, is to apply a search operator (e.g., a hyphen) to indicate that certain terms must not occur in the search results (negation). Accordingly, by automatically selecting topical terms to negate, constructing a query, and embedding the negation in a link with each results page result, considerable manual and cognitive effort is saved. | 08-08-2013 |

20140296057 | MITIGATION OF PLUGGING IN HYDROPROCESSING REACTORS - The behavior of a monitored condition over time for a reactor or reaction system can be analyzed using groupings or windows of data to identify anomalous features in the time-average values. Anomalous features can be identified based on a threshold value generated from the analysis. Based on identification of an anomalous feature, a corrective action can be taken. For example, when the monitored condition is the pressure drop across a catalyst bed, detection of an anomaly can indicate the time to initiate a wash process for the catalyst bed before a large drop in catalyst activity occurs. By detecting an anomaly at an earlier point in time, a wash cycle can be initiated earlier so that the wash is more effective at restoring the catalyst bed to a desired condition. | 10-02-2014 |
