For the load affected by many factors and near the far smaller feature, a hybrid load forecasting method based on fuzzy support vector machine and linear extrapolation is proposed. The similar day is selected by the integrated effects of meteorology and time, and the fuzzy membership of the corresponding training sample is obtained by normalized similarity. Using the fuzzy support vector machine to...
In the three-dimensional sensor network scenarios, a three-dimensional positioning algorithm, according to the bounding cube algorithm, which is based on the intersection of the ball field for wireless sensor networks, is presented. Also, possible coordinates of the unknown nodes are determined. The principle of this algorithm is studied and realization method of simulation is experimented by MATLAB...
The naval gun is a traditional navy weapon, which takes warship as the carrier. In modern naval ships, the small and medium caliber naval guns, which have quick response and high launch rate, is the main attack weapons in naval vessels. The level degree of the naval gun platform has a great influence on the launch accuracy. This paper mainly studied a platform angle dynamic measurement system based...
Concrete composite wall system is an innovated composite structure system. Tow RC coupled composite walls were tested quasi-statically under low cyclic lateral loads. The characteristics including failure modes, bearing capacity, stiffness degradation, ductility and hysteretic characteristics are investigated. It is shown that on the elastic stage, the precast slabs and frame could work together very...
Based on the principle of Mahalanobis distance discriminant analysis, the discrimination of influential degree of the different index to optimization of supporting programs for deep foundation pit is taken into account, using the weights obtained by the analytic hierarchy process to modify the Mahalanobis distance, by the new calculation method of covariance matrix, the weighted distance discreminant...
In this report we have presented a spectroscopic and CW laser characterization of an efficient thulium doped GPNG bulk germanate glass pumped at 792 nm by Ti: Sapphire radiation. Laser characterization gave a maximum slope efficiency of 50 % comparable to the crystalline counterparts and we believe, to the best of our knowledge, this being the best for Tm-doped bulk glass lasers. The maximum output...
This paper presents an integration framework of wisdoms of experts with different field knowledge and experiences for complex system analysis . We call these experts as realm experts in the paper. Hall for workshop of meta-synthetic engineering (HWME), proposed by QIAN Xue-sen, is an accepted important method for complex system analysis. After briefly reviewing the research situation of complex system...
