| 20100114869 | GENERATING A QUERY PLAN FOR ESTIMATING A NUMBER OF UNIQUE ATTRIBUTES IN A DATABASE - In a method for generating a query plan for estimating a number of unique entry counts of an attribute in a database, a sample of entries in the database is identified, at least one of a sampling percent and a coefficient of variance of the entries in the sample is identified, and a skewness of the entries in the sample is calculated. In addition, at least one of a plurality of estimators is selected based upon the skewness of the entries and at least one of the sampling percent and the coefficient of variance of the entries in the sample. Moreover, a query plan is generated from the selected at least one of the plurality of estimators. A query optimizer for performing the method is provided. | 05-06-2010 |

| 20110202528 | SYSTEM AND METHOD FOR IDENTIFYING FRESH INFORMATION IN A DOCUMENT SET - A method of identifying a fresh document in a document set is provided. The method may include obtaining a query document that is included in a document set comprising a plurality of documents. The method may also include grouping the plurality of documents into a plurality of fine clusters based on a textual similarity between the plurality of documents. The method may also include identifying a target fine cluster within the plurality of fine clusters, the target fine cluster including the query document. The method may also include ordering the documents included in the target fine cluster by time to identify the fresh document. The method may also include generating a query response that includes the fresh document. | 08-18-2011 |
| 20110202535 | SYSTEM AND METHOD FOR DETERMINING THE PROVENANCE OF A DOCUMENT - A method of identifying a provenance of a document is provided. The method may include obtaining a query document that is included in a document set comprising a plurality of documents. The method may also include grouping the plurality of documents into a plurality of fine clusters based on a textual similarity between the plurality of documents. The method may also include identifying a target fine cluster within the plurality of fine clusters, the target fine cluster including the query document. The method may also include ordering the documents included in the target fine cluster based, at least in part, on metadata associated with each of the documents to identify a source document. The method may also include generating a query response that includes the source document. | 08-18-2011 |
| 20110202886 | SYSTEM AND METHOD FOR DISPLAYING DOCUMENTS - A computer system that includes a graphical user interface used to organize a group of documents is provided. The system includes a processor that is adapted to execute machine-readable instructions. The system also includes a storage device that is adapted to store data. The data includes a plurality of documents and instructions that are executable by the processor to generate the graphical user interface. The graphical user interface includes a cluster map that includes the results of a clustering algorithm applied to the documents. The graphical user interface also includes a principal documents screen that includes a principal document that is identified by weighting each of the documents in a cluster based, at least in part, on an occurrence of representative terms in the document. The representative terms are terms that have been identified by the clustering algorithm as being more effective for distinguishing between documents that belong to different clusters. | 08-18-2011 |

| 20090139546 | PROCESS FOR ACIDIC CLEANING IN THE BEER INDUSTRY - The present invention relates to the acidic cleaning in the beer industry, and more particularly an improved process for acidic cleaning of the various elements and vessels that are used in the preparation of beer and other and other related fermented beverages, said cleaning being carried out by using a formulation comprising at least one alkane sulphonic acid. | 06-04-2009 |
| 20100229898 | METHOD FOR CLEANING SURFACES OF POLYOLEFIN-BASED MATERIALS SOILED WITH FOOD, PARTICULARLY DAIRY PRODUCTS - The invention relates to a method for cleaning surfaces of polyolefin-based materials soiled with food, particularly dairy products. More specifically, the invention relates to a method for cleaning materials based on one or more halogenated or non-halogenated polyolefins and soiled with food, particularly dairy products, which method is particularly safe for the environment, but also for the soiled polyolefin-based material with minimal wear and tear. According to the invention, the soiled material is brought into contact with an aqueous composition based on alkane sulfonic acids having between 1 and 4 carbon atoms. | 09-16-2010 |
| 20100313908 | Use of Alkanesulfonic Acid as Agent for Cleaning Cement, Mortar and Concrete - The present invention relates to the use of at least one alkanesulfonic acid of formula R—SO | 12-16-2010 |

| 20090273549 | IMPROVEMENTS TO BISTABLE NEMATIC LIQUID CRYSTAL DISPLAYS - A method for addressing a bistable nematic matrix LCD having two stable textures without any applied electric field. Pixel addressing is of the passive multiplex type. The method includes selecting the value of the electrical voltage applied between the substrates so that an average value of the voltage, preferably the average quadratic value, since the initial command for image display up to the time immediately preceding switching, has a predetermined value independent of the information to be displayed, which is the same for all the pixels of the image. | 11-05-2009 |
| 20100007652 | LIQUID CRYSTAL DISPLAY DEVICE WITH IMPROVED SWITCHING MEANS - The invention relates to a method for controlling a liquid crystal display, comprising a matrix of pixels arranged in crossed lines and columns and in which a switch in the state of the liquid crystal molecules, controlled by application of an electric control signal between two electrodes ( | 01-14-2010 |
| 20110063536 | LIQUID CRYSTAL DISPLAY DEVICE WITH ADVANCED MEANS FOR SWITCHING - This present invention relates a method for the control of a liquid crystal display that includes a matrix of pixels arranged in crossed lines and columns and in which a switching of state of the liquid crystal molecules, controlled by application of an electrical control signal between two electrodes ( | 03-17-2011 |
