Abstract: Existing program code, which is executable on one or more computers forming part of a distributed computer system, is analyzed. The analysis identifies log output instructions present in the program code. Log output instructions are those statements or other code that generate log messages related to service requests processed by the program code. A log model is generated using the analysis. The log model is representative of causal relationships among service requests defined by the program code. The log model can then be applied to logs containing log messages generated by execution of the program code, during its normal operation, to group log messages for improved analysis, including visualization, of the performance and behaviour of the distributed computer system.

Abstract: A luminaire is disclosed. The luminaire includes a light socket, at least one heat insulation sheet, and at least one light emitting module. The heat insulation sheet is arranged between the light socket and the light emitting module. Thus heat from a driver power in the light socket and heat from the light emitting module will not be affected by each other. The light socket further includes a main body and a case made from metal. The case is mounted on the main body for fixing the main body on the light emitting module and being subject to gravity force of the light emitting module. Thereby the problem of deformation of the main body caused by the gravity force of the light emitting module is solved when the luminaire is used at high temperature. Thus the service life of the luminaire is extended.

Abstract: Techniques are disclosed for a facial expression classification. In an embodiment, a multi-class classifier is trained using labelled training images, each training image including a facial expression. The trained classifier is then used to predict expressions for unlabelled video frames, whereby each frame is effectively labelled with a predicted expression. In addition, each predicted expression can be associated with a confidence score. Anchor frames can then be identified in the labelled video frames, based on the confidence scores of those frames (anchor frames are frames having a confidence score above an established threshold). Then, for each labelled video frame between two anchor frames, the predicted expression is refined or otherwise updated using interpolation, thereby providing a set of video frames having calibrated expression labels.
