The apparatus comprises a defining module configured for defining a normal-condition data set may comprise data values of the variables when the industrial process is operating under a normal condition and for defining an abnormal-condition data set may comprise data values of the variables when the industrial process is operating under an abnormal condition; a modelling module configured for modelling a normal-condition model from the normal-condition data set and modelling an abnormal-condition model from the abnormal-condition data set; a plotting module configured for plotting a normal-condition plot from the normal-condition model and plotting an abnormal-condition plot from the abnormal-condition model; and an analysis module configured for analysing live data values of the variables for simultaneous display with the normal-condition plot and the abnormal-condition plot.11-11-2010
20130151219MULTI-PARAMETER BIT RESPONSE MODEL - A method of generating a directional response of a drill bit based on one or more drilling parameters includes performing actual or simulated tests with a drill bit in a test material having a strength under different experimental drilling parameters and recording the results of the plurality of tests. A representation of an expected directional response of the drill bit is formed based on the results. Current drilling parameters are receiving current drilling parameters at a computing device and the directional response is generated based on the current drilling parameters by utilizing the representation.06-13-2013
20130151220MULTI-ECU SIMIULATION BY USING 2-LAYER PERIPHERALS WITH LOOK-AHEAD TIME - A method and system where a plurality of ECU is rapidly executed while avoiding deadlock by performing conservative event synchronization. The simulation system is provided with 4 layers, namely a processor emulator which is an ECU emulator, a plant simulator, a external peripheral scheduler, and a mutual peripheral scheduler. The external peripheral scheduler performs advanced execution of the plant simulator only during processor emulator reaction delay time (or the time until the next event). The notification to perform advanced execution of the processor emulator is provided until the actual plant simulator stop time. The mutual peripheral scheduler provides notification to the processor emulator to perform advanced execution only during communication delay timing between processor emulators (or the time until the next event). The processor emulator conservatively processes until the earliest time of the notification times. Each peripheral proceeds with processing until the earliest time of the accepted events.06-13-2013
20120029892CONDITION MONITORING OF WINDTURBINES - A method for monitoring a wind turbine is provided. The method includes defining at least one subsystem of the wind turbine and providing a simulation model for the at least one subsystem. During normal operation of the wind turbine at least an input parameter of the at least one subsystem is determined A behavior of the at least one subsystem is simulated using the at least one input parameter as an input of the simulation model. Based on the simulated behavior, it is determined, if the at least one subsystem operates within a given specification.02-02-2012
