During the coal cutting process in mines, the drill stem is easy to be deflected in virtue of the complicated geological conditions. The deviation control of drill stems is of great significance for the production efficiency and service life of drill stems. Based on analyzing influence factors of the deflection of drills, this paper builds up a model to describe deflecting forces of the coal seam...
Home energy management attracts more and more attention in both academic and power system. Comfort requirements of occupants are necessary to be considered, which are directly affected by the human behavior. Thus profiling the unpredictable comfort requirements of occupants is one of the challenging problems. In this paper, a human behavior cognition method is proposed to predict the users' occasional...
Fuzzy C-Means (FCM) clustering is the most well-known clustering method according to fuzzy partition for pattern classification. However, there are some disadvantages of using that clustering method, such as computational complexity and execution time. Therefore, to solve these drawbacks of FCM, the two-phase FCM procedure has been proposed in this study. Compared with the conventional FCM, the usage...
Bad data injection is one of most dangerous attacks in smart grid, as it might lead to energy theft on the end users and device breakdown on the power generation. The attackers can construct the bad data evading the bad data detection mechanisms in power system. In this paper, a novel method, named as Adaptive Partitioning State Estimation (APSE), is proposed to detect bad data injection attack. The...
We address the problem of Chinese semantic dependency parsing. Dependency parsing is traditionally oriented to syntax analysis, which we denote by syntactic dependency parsing to distinguish it from semantic dependency parsing. In this paper, firstly we compare Chinese semantic dependency parsing and syntactic dependency parsing systematically, showing that syntactic dependency parsing can potentially...
When modeling the complex economic systems, a target system often need to be categorized into a certain clusters by FCM. The optimal cluster number often is dependent of the selected cluster validity function, but there are so many validity functions proposed, it is difficult to get the optimal cluster number in real target system. A method to get the optimal cluster number of FCM in real systems...
