In this paper, we describe a novel local descriptor of image texture representation for visual recognition. The image features based on micro-descriptors such as local binary patterns (LBP) and local ternary patterns (LTP) have been very successful in number of applications including face recognition and texture analysis. Instead of binary quantization in LBP, LTP thresholds the differential values...
Power control of superconducting magnetic energy storage plays an important role in realizing its applications in power system. Taking current source converter and voltage source converter as research objects, this paper discusses a SPWM switching strategy , which realizes effective control of amplitude and phase of converter's AC current. On this basis, this paper presents a power control method...
Aiming at the uncertain information in the multi-objective assessment for aviation ammunition maintenance quality, the model adopts the deviation degree of the interval number to determine the attribute weight, and uses WAA operator to obtain the comprehensive attribute value of the scheme. According to the possibility matrix, it gains the sequencing vector, so as to get the assessment scheme. The...
The energy and defect mode properties of one dimensional ternary photonic crystals with left-handed medium (LHM) were investigated by transfer matrix method. It was demonstrated that the transmission became tunable, depending on the thickness and the refraction index of the slabs deeply: as the thickness of LHM slab in the structure became wider, the Bragg gap shifted toward higher frequency, in sharp...
Using the plastic-plate of rice seedling, we studied that phosphogypsum as acidifier in affected on the growth of rice seedling. It was shown that phosphogypsum could adjust soil pH value of into the pH range of rice seedling growing, which had increased effectively plant height, root length, dry weight, chlorophyll content and root activity of rice seedling. Phosphogypsum treatment mixed sulfuric...
This paper proposes a new environmental friendly evaluation criterion to assess the comprehensive performance of coal-fired power plant. The new evaluation criterion, which is called the comprehensive Index of Energy, Resources and Environment (IERE), can synthetically evaluate the thermal, economical and environmental performance of power plants. Based on the new criterion, the paper analyzes the...
A cluster of improved safety indices for the connection models in 10 kV distribution network is raised based on k(n-1+1) safety criterion. These indices apply to describe not only the security of radial connection mode but also ring-type connection mode, such as "N-1" connection, sub-liaison connection, 4??6 connection and so on. Among these indices, the severity index of faults depicts...
A method of load fusion is proposed to achieve the subregional and phased planning of best connection modes in 10 kV distribution system based on model design. The best connection mode of the medium-sized region is obtained before considering small corners, and then the load of these corners is fused into the main region by using the model presented in this paper; finally the best connection of the...
A new method of basic element is proposed to classify distribution network connection modes. Basic element is the smallest connection mode with characters of integrity and independent operation in distribution system. Then a dynamic and comprehensive evaluation criterion of basic element connection mode is raised based on fuzzy membership function, to achieve the dynamic and intelligent selection...
Existing network damage assessment method fall short because they either lack correlation adjustment among indexes or without conclusive evidence to demonstrated the degree does represent the real situation of the network. This paper proposed a method to adjustment index correlation based on Orthogonalization. The advantages of this method for evaluation damage degree of network have been demonstrated...
This paper describes one valid framework of integrating intensity discontinuity and edge continuity for image Straight-line Extraction. First, multiple "edge contours" are traced out from digital image by means of classic LOG algorithm and contour tracing principle. In this step, Zero-Cross points are detected without implementing traditional "edge labeling" procedure and thus,...
