  • Patent number: 10417569
    Abstract: A method for detecting deviations between an event log and a process model includes converting the process model into a probability process model, the probability process model comprising multiple nodes in multiple hierarchies and probability distribution associated with the multiple nodes, a leaf node among the multiple nodes corresponding to an activity in the process model; detecting differences between at least one event sequence contained in the event log and the probability process model according to a correspondence relationship; and identifying the differences as the deviations in response to the differences exceeding a predefined threshold; wherein the correspondence relationship describes a correspondence relationship between an event in one event sequence of the at least one event sequence and a leaf node in the probability process model.

  • Patent number: 10417023
    Abstract: A GPU simulation method. An instruction sequence of a client GPU is intercepted in a kernel state simulator based on system virtualization and GPU using principle, and a mechanism is selected according to user configuration to accomplish simulation of the client GPU. In first mechanism, instruction translation is accomplished on low-level semantics based on a binary translation technology, and instructions are executed on a host GPU; in second mechanism, instruction conversion is accomplished using an existing GPU software stack, and instructions are executed on host GPU. The method provides an efficient simulated GPU for a virtual machine based on a host machine physical GPU, and solves the problem of slow GPU simulation. Based on a system virtualization technology and by virtue of a convenient condition provided by an existing GPU software stack, the GPU simulation speed is improved, and the implementation difficulty and complexity of the method are effectively controlled.

  • Patent number: 10419111
    Abstract: The present disclosure provides example data transmission methods and apparatuses. One example method includes obtaining a radio signal by using an input port. Based on a correspondence between an input port and a bearer channel, a bearer channel corresponding to the radio signal is determined. Code Division Multiple Access (CDMA) modulation and carrier modulation on the radio signal are performed according to a codeword and a frequency sub-band corresponding to the bearer channel, to obtain a modulated electrical signal. The modulated electrical signal is then modulated to an optical wavelength corresponding to the bearer channel to obtain a modulated optical signal, and the modulated optical signal is sent to an optical network.

  • Patent number: 10416704
    Abstract: A method and a structure for determining a global clock among systems are disclosed. When a standardized time reference is required among systems, a reference clock source may transmit a calibration signal, and a transmitting time Td (0) may be recorded. Each system may respectively record an arrival time Ta (n), transmit a return signal to a signal recording unit of the reference clock source, and record a transmitting time Tb (n), after receiving the calibration signal. Similarly, because of different distances, the signal recording unit may record arrival times Td (n) of the return signals subsequently, and determine time delays Delay (n) between systems and the reference clock source respectively. When all the systems are required to have a completely standardized time reference, a corresponding Delay (n) may be acquired and transmitted to each system.
