The cost-optimal trend in global competitive environment has led to lean, complex and consequently vulnerable supply chains. This vulnerability is high due to the presence of increasing dependency in lean supply chain networks. Hence, it is essential for companies to regulate the supply chain network structure and information sharing strategies so as to be more resilient to disruptions/risks. In order...
In this paper, the three active components in Scutellaria Extract were rapidly determinate by near-infrared reflectance spectroscopy (NIRS). 100 samples of Scutellaria Extract from 12 different pharmaceutical factories were divided into a calibration set (80 samples) and a validation set (20 samples). In combination with the partical least square (PLS), the quantitative calibration models were established,...
Raised chest is main body feature of female, and the rational design of chest makes a direct impact on garment aesthetics and fitness. In pattern design, the difference of chest chiefly displays in the front and back waist length. Based on 3D point-cloud data, this paper probes the relationship of the front and back waist length and human body style, and its determining method. Read and optimize the...
In this research, Point-cloud diagrams can be obtained by using 3D body scanner and then characteristic positions of the body (such as waist, abdomen and buttocks) can be confirmed. Then height of characteristic positions can be measured from diagrams by the software of Image-ware. The correlation relationship between height of characteristic positions and height can be analyzed by the software SPSS16...
First, the false peak of Burg Spectrum estimation is introduced. In this paper, a new method of eliminating false peak based on Empirical Mode Decomposition is proposed. Secondly, this new method is used in the Line spectrum analysis of ship radiated noise simulation signal. Compared with traditional Linear Spectrum analysis, it is a better method for signal analysis and processing.
Compared to the traditional laboratorial measure method, the spectroscopy method is more excellent and non-destructive to measure the content of chlorophyll. The aim of the paper was to determine the contents of chlorophyll in winter wheat by reflective spectroscopy. Pretreatment method of orthogonal signal correction (OSC) was used to reject uncorrelated variables in the original spectrums before...
Taking daily data of Shanghai metro passenger flow as research object, an index of `n-day' average passenger flow volume is introduced to construct “time-series”,the change rate of daily volume against `7-day' average was used for analyzing the characteristics of working day passenger flow.On this basis, the research constructs ARIMA forecast model for Daily Passenger Flow of Shanghai Metro is constructed...
To identify the photosynthetic mechanism of nitrogen (N) absorption and utilization in different rice (Oryza sativa L.) genotypes, relationships between photosynthetic characteristics of flag leaf and N use efficiency were investigated in 6 N-efficient and 6 N-inefficient rice genotypes with variable N use efficiency. The abilities of seed setting of the genotypes were also analyzed. The N application...
Combining the human visual system with the image local properties, this paper proposes a novel watermarking algorithm based on ridgelet transform and fuzzy c-means (FCM) clustering. In order to obtain a sparse representation of the image, especially for straight edge singularity, the image is first partitioned into small pieces and the ridgelet transform is applied for each piece. The image pieces...
Two new DOA (Direction Of Arrival) estimation methods based on orthogonal joint diagonalization using Jacobi rotation are proposed. Through processing spatio-temporal correlation matrices and high-order cumulant matrices by the new technique, the spatial spectrum can be redefined by the joint diagonalization matrix and a set of diagonal matrices. At the same time, these methods are also justified...
3D watermarking methods have been proposed to protect the copyright of 3D models. Commonly-used irregular triangle mesh blocks the development of 3D watermarking techniques. In this paper, a novel non-blind 3D watermarking method is proposed based on geometry image, which is a regular 2D grid representation of 3D models. A color image watermarking algorithm in DCT transform domain is applied during...
Effective customer satisfaction evaluation is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we establish the power customer satisfaction evaluation index system based on previous studies. Then we prove the validity of this method through field investigations by using AMOS. Finally, path coefficient analysis is conducted to get key factors to improve...
