By an analysis of current situation of Jatropha in panzhihua studied to fully understand current defects and problems in development of Jatropha in panzhihua, targeted the corresponding solutions, provided for the development of Jatropha in panzhihua century strategies. Using a mathematical method to quantify the lack of Jatropha development described, identify the major contradictions. By hierarchical...
In order to study ground grids with varied aspect ratio impact on grounding impedance, this paper considers the characteristics of the transient electromagnetic conductors and compares frequency characteristic curve of grounding impedance, after the simulation and calculation based on the CDEGS, which is famous for measuring the grounding resistance in the world. The results show the inductive component...
The grounding system is an important measure to maintain reliable operation of power systems and ensure the safe of equipment and human body. Grounding resistance is an important parameter to judge whether the grounding system meets the requirements. This paper aims to study the frequency characteristics of grounding resistance in non-uniform soil regions. By using the software CDEGS, a three-layered...
Biomedical Named Entity Recognition (Bio-NER) plays a fundamental role in biomedical text mining. The improvement of the Bio-NER module's performance always brings notable enhancement to the entire text mining system. Treating the Bio-NER task as a sequence labeling problem, this paper proposes a generative approach to address it. By adopting the spirit of Sequence Memoizer, our approach gives reasonable...
In this paper, fault diagnosis model based on the fusion of hybrid neural network (HNN) and ant colony optimization algorithm (ACOA) is presented. The associated rules are extracted based on rough set theory and are used as the theoretic basis of the connection mechanism of higher-order NN, which was composed with the feedforward NN, the hybrid NN model is constructed. ACOA was used to optimize solving...
Distributed denial of service (DDoS) attack is among the hardest network problems. Among several countermeasures, packet marking scheme is promising. In these schemes, every router marks a passing packet with a probability, so that the convergence time for an attacking path can be achieved in little time, and the attack can be found in attack path reconstruction using IP traceback. In this paper,...
