Business processes change over time in response to changing circumstances, it is crucial for process managers to discover and understand such changes from event logs. While existing techniques in process mining cannot efficiently detect and locate concept drifts in uncompleted event logs. Hence, an appropriate method, which could prompt to unravel the process evolution, may greatly assist organizations...
During the design of the second-phase extension project of a fuel electric plant in China, in order to meet the technological requirements, a typical oval steel coal scuttle with double funnels was proposed. This kind of scuttle has a complicated geometrical shape and is difficult to be designed and built. To evaluate the mechanical behavior of this scuttle, the 3D finite element structural analysis...
In this letter, an efficient direction-of-arrival (DOA) estimation method is proposed with a uniform linear array when uncorrelated and coherent signals coexist. The method can effectively eliminate the possible false DOA estimates of uncorrelated signals, and only the true DOA estimates can be retained. After estimating the DOAs and power of uncorrelated signals, the information in them can be eliminated...
