Abstract: A vehicle body part (60) has a perforated grid portion (61) secured in an aperture in a non-perforated portion (601,602), an edge portion of the grid portion defining part of the edge of the body part. A support member (8) extends along the edge portion of the grid portion (60) and supported from the non-perforated portion (601,602), and a seal (9) for contact with an adjacent body part extends around at least said part of the edge of the body part. The seal has a cross-section which includes a first lobe (9c) which covers the edge portion of the grid (61) to protect a vehicle operator from injury by this edge portion and improving styling. The seal cross-section also has a second lobe (9d) which extends between the grid (61) and the support member (8) to prevent vibration of the grid and damage of the paint finish of these components. The seal cross-section also includes a U-shaped channel portion (9a) which encloses the edge of the support member (8).

Abstract: For migrating process instances, first input information describing changes between a first process template and a second process template is received. Second input information describing grouping of said changes is also received. A set of combinations of the first process template and the second process template is determined by applying the changes to the first process template in complete groups as defined by the second input information.

Abstract: Transactions within a process model are determined by grouping a set of individual process activities into a single transaction. This effectively reduces the processing overhead, and, therefore, improves the overall throughput and latency of the execution of the process model. The transaction is determined by performing an optimization procedure that takes into account the structure of the process model as well as various properties of the single process activities of the process model. Analysis of the properties of the process activities as well as application of the optimization procedure is performed dynamically during execution of the process model by a workflow engine.

Abstract: The present invention provides a method, a data processing system as well as a computer program product for optimizing process properties for workflows with failing activities. The invention makes use of monitoring occurrence of failure of each activity of a process model of a workflow and further monitoring properties that are associated to compensating activities that are required in order to repair the failure of an activity. The method makes explicit use of determining alternative execution sequences and selecting one of the plurality of alternative execution sequences of the process model, that optimizes the process property in case of failure of an activity of the process model. The process model itself remains unaffected and need not to be remodeled.

Abstract: The present invention relates to a micro cell system (1) with a membrane electrode assembly (MEA) (2) which in each case is covered on the cathode-side and anode-side with a current collector foil (3, 4). The current collector foils in each case comprise at least one gas-permeable opening (5, 6). On at least one of the current collector foils (3, 4) on a side facing the MEA (2) there are arranged diffusion channels (7, 8) These replace e.g. porous or fleece-like gas diffusion layers and thus alone ensure the micro-diffusion of gas on the MEA (2) The diffusion channels for this are connected to the gas-permeable opening (5, 6) for leading through gas, and the webs (9, 10) of the diffusion channels are provided with an electrically conductive surface (11, 12) for contacting the MEA.
