20120215751 | TRANSACTION PREDICTION MODELING METHOD - The present invention provides database systems configured for creating and utilizing a transactions predictive model using a computer, the database system including: a database management system (DBMS) for handling transactions in the database system, the DBMS including a prediction component for generating the transactions predictive model; a database workload table for capturing commands associated with the transactions, the commands utilized for generating the transactions predictive model; database data for providing data in response to the transactions; and a prediction model database for storing the transactions predictive model, where the prediction component is configured for generating a generalized statement for each statement corresponding with the transactions, identifying a sequence of transactions of the transactions, creating a transaction class based on the sequence of transactions, identifying a current transaction, and then calculating probabilities between transactions, where each statement includes at least a database command. | 08-23-2012 |
20130159283 | INTERMEDIATE RESULT SET CACHING FOR A DATABASE SYSTEM - A method for storing intermediate result sets in a database is provided. An access plan for a single query for accessing data stored in the database system is received. An intermediate result set is generated during execution of the access plan. A value of an intermediate result set rating of the intermediate result set is determined during execution of the access plan at runtime of the query for determining if the intermediate result set, generated during the execution of the access plan, is to be stored. Based on determining that the value of the intermediate result set rating meets a predefined criterion, the determined intermediate result set is stored for a longer period of time than the runtime of the query as a stored intermediate result set. | 06-20-2013 |

20110182789 | EXHAUST GAS AFTERTREATMENT SYSTEM - An exhaust gas post treatment system for, in particular, a self-igniting internal combustion engine including a catalytic converter that is arranged in an exhaust gas line, a fine particle filter and an introduction device for a reduction agent arranged upstream of the catalytic converter in the direction of the flow of the exhaust gas, and to a method for operating said type of exhaust gas post treatment system. An exhaust gas post treatment system and a method for operating said type of system that is simple to use and compact. This is achieved by virtue of the fact that the catalytic converter is a reductively or oxidatively operated catalytic converter, or that the introduction device, the catalytic converter, that can be operated reductively or oxidatively, and the fine particle filter are arranged in said sequence and in the exhaust line in the direction of flow. | 07-28-2011 |
20110258987 | VAPORIZER - A vaporizer device which works together with an exhaust pipe carrying process exhaust gas. An exhaust duct of the vaporizer device opens into the exhaust pipe. The vaporizer device has a burner comprising an injection device for fuel and air, a combustion chamber, and the exhaust duct. An exhaust gas aftertreatment device is inserted into the exhaust pipe downstream of the junction with the exhaust duct. A method for the operation of such a vaporizer device. According to the invention, a vaporizer device and a method for the operation of such a vaporizer device are provided, and are expanded or improved with respect to the functionality thereof. This is achieved in that an introduction device for the vaporizable liquid is inserted into the exhaust duct. The corresponding method is characterized in that the burner provides sufficient thermal energy, wherein the lower limit thereof is prespecified by the provision of an amount of energy which is sufficient for the vaporization of an amount of vaporizable liquid which is larger than the amount of vaporizable liquid introduced into the exhaust duct. | 10-27-2011 |

20120117949 | EXHAUST GAS AFTERTREATMENT SYSTEM - The invention relates to an exhaust gas post treatment system for an internal combustion engine, including an intake device for taking hydrocarbons into an exhaust gas pipe carrying the exhaust process gas from the internal combustion engine and a treatment device through which exhaust process gas flows downstream of the intake location and which increases the exhaust process gas temperature by means of oxidation of the hydrocarbons taken in. The invention specifies an exhaust gas post treatment system and a method for operating such an exhaust gas post treatment system which can be implemented cost-effectively. This is achieved in that the treatment device has catalytically coated components, in that the hydrocarbons are at least partly evaporated in the intake device and are modified chemically by means of cracking reactions and/or by means of partial oxidation, and in that the proportion of platinum, at least in a subregion of the catalytic coating of the components, is less than 50% of the overall mass of all the catalytically active substances in this sub region of the coating. | 05-17-2012 |

20130089258 | METHOD AND APPARATUS FOR REMOVING A VISUAL OBJECT FROM A VISUAL DATA STREAM - Methods and apparatuses for removing a visual object from a visual data stream. A live visual data stream containing present and subsequent images is received. A visual object is selected by defining a contour. A binary mask based on said contour is determined. Starting at the coarsest layer, regions outside the mask for replacing a region within the mask are selected. The region within the mask is replaced by content of the selected regions. The selecting and the replacing are successively repeated at each of the finer layers of the resolution pyramid finishing at the finest layer. The repeated replacing is also based on the content replaced at the next coarser layer. The step of determining a binary mask, calculating a resolution pyramid, and repeated selecting and repeated replacing are repeated for the received subsequent image. The repeated replacing is also based on the content replaced in the preceding image. | 04-11-2013 |
