20080281659 | Method and Apparatus for Optimization in Workflow Management Systems - Activities within a workflow are either data management activities (DMAs) or non-DMAs. A workflow is typically carried out by a system by executing one activity after the other. This can, however, be very time consuming. A method and system are provided for optimizing a group of activities (GOA) comprising a DMA, whereby the GOA is comprised in the workflow to improve the overall performance. The method determines the DMAs, and for each DMA, a data level statement (DLS). The GOA is determined and a process graph model (PGM) is determined from the GOA so that the DLS is comprised in the PGM and the semantics of the PGM are identical to those of the GOA. The PGM is optimized for which an optimized GOA is determined. The semantics of the optimized GOA are identical to those of the GOA. In the workflow, the GOA is replaced by the optimized GOA. | 11-13-2008 |
20120227055 | Workflow Processing System and Method with Database System Support - Methods and apparatus, including computer program products, implementing and using techniques for automatic workflow processing in a workflow processing computer system. A data management system support module receives a data management activity description, determines a set of set references associated with the data management activity, determines a set of data sources associated with the set of set references within a data management system, determines whether the data management system includes infrastructure for accessing the references and for accessing the data sources, in response to determining that the infrastructure is not included, automatically creates the infrastructure from information in a metadata repository coupled to the data management system, replaces in the data management activity description references to set references and references to data sources by references to the infrastructure in the data management system, and delivers the data management activity description for execution by the system. | 09-06-2012 |

20110153664 | Selective Storing of Mining Models for Enabling Interactive Data Mining - Computerized methods, data processing systems, and computer program products for storing of data mining models (DMMs) are provided. A new DMM is created having at least one of the following characteristics: quality and complexity. The new DMM is handled as a candidate for storing in a storage device if a predefined criterion for the characteristics is met. The sum of the sizes of the new DMM and already stored DMMs is determined In response to the sum falling below a storage limit, the new DMM is stored in the storage device. In response to the sum exceeding the storage limit, a decision is taken based on priorities of the DMMs which DMMs to store in the storage device. The priorities depend at least on access frequencies of the DMMs. Upon a data mining request, a corresponding DMM is determined and a user is requested to confirm that data mining is to proceed if quality of the determined DMM does not fulfill a further predefined criterion. | 06-23-2011 |

20150040758 | METHOD AND APPARATUS FOR CRYOGEN-FREE CONCENTRATION OF A HYPERPOLARIZED GAS IN A CONTINUOUSLY FLOWING STREAM OF GAS, AND USE - The present disclosure refers to a method and an apparatus for cryogen-free concentration of a hyperpolarized noble gas in a continuously flowing stream of gas. The method comprises the following steps: providing a mixture of gases containing hyperpolarized noble gas and at least one process gas; passing the prepared gas mixture as a continuously flowing stream of gas through a gas separation device with a semipermeable membrane in order to separate the gases; and concentrating the hyperpolarized noble gas in the gas separation device, in which at least part of the at least one process gas or the hyperpolarized noble gas is separated from the continuously flowing stream of gas by means of the semipermeable membrane. It also provides for the use of a continuous stream of gas with concentrated hyperpolarized noble gas for magnetic resonance spectroscopy or magnetic resonance tomography. | 02-12-2015 |

20120085603 | Brake Disk - A brake disk for a motor vehicle is provided. The brake disk includes a brake disk chamber and a friction ring arranged coaxially thereto, an outer casing surface of the brake disk chamber having a profile, which for torque transmission, engages in a complementary profile of an inner casing surface of the friction ring, and the friction ring being arranged axially secured to the brake disk chamber. At least one tab for axial securing is formed on the outer casing surface of the brake disk chamber. | 04-12-2012 |
