摘要: Mass based methods and systems for estimating soot load in a filter of an after-treatment system for exhaust stream are provided. The after-treatment system can comprise a sensor, a filter, and a processor configured to estimate soot load in the filter based on a mass based multi-layer model. An example system includes a virtual sensor comprising an estimator for providing information corresponding to a filter outlet NO2 concentration. An example method includes the steps of providing the mass based multi-layer model, passing the exhaust stream through the filter, and using the sensor to monitor a condition of the exhaust stream. The example method further includes the steps of calculating a total regeneration rate based on the multi-layer model by solving a second-order ordinary differential equation with a plurality of parameters using an analytical approach, and estimating the soot load based on the calculated total regeneration rate.

摘要: A method of controlling the operation of a particulate filter in an exhaust gas after-treatment system may comprise calculating a ratio of particulate loading rate to filter regeneration rate using a mass-based soot load estimation scheme and comparing the ratio of particulate loading rate to filter regeneration rate to a predetermined threshold value. The method may further comprise controlling operating conditions of the particulate filter to maintain the ratio of particulate loading rate to filter regeneration rate at a value above the predetermined threshold value.

摘要: A method for video playback switching in response to changing network conditions. The method includes accessing a server to retrieve respective index files for a low bit rate version and a high bit rate version of the video file, and instantiating a low bit rate media player and a high bit rate media. Playback of the video file is begun by the high bit rate media player streaming the high bit rate version from the server. Upon an indication of impeded network conditions, a transition point is selected, wherein the transition point indicates where downloading of the high bit rate version stops and where downloading of the low bit rate version begins. The low bit rate media player is then positioned to begin playback at the transition point. Playback of the video file is then switched to the low bit rate player upon encountering the transition point.

摘要: A system and process for capturing and rendering ink is described. An ink canvas object may contain none, one, or more objects or elements and may specify the z-order of the objects or elements. The ink canvas object may host a variety of objects or elements and, therefore, provide ink functionality to the objects or elements, even though the objects or elements themselves may not have ink functionality.

摘要: A system and method for erasing ink is described. Using an erasing contour, the system determines closest points which come close to or contacts the erasing contour when it encounters an ink stroke. Portions of an ink stroke may then be erased when the erasing contour contacts the ink stroke.

摘要: A system and process for capturing and rendering ink is described. An ink canvas object may contain none, one, or more objects or elements and may specify the z-order of the objects or elements. The ink canvas object may host a variety of objects or elements and, therefore, provide ink functionality to the objects or elements, even though the objects or elements themselves may not have ink functionality. The ink canvas object is attached to an ink editor that has an associated modifiable ink editor behavior, whereby ink specific behaviors are collected in the ink edit behavior.
