Three-color mixing for classifying agricultural products for safety and quality

A three-color mixing application for food safety inspection is presented. It is shown that the chromaticness of the visual signal resulting from the three-color mixing achieved through our device is directly related to the three-band ratio of light intensity at three selected wavebands. An optical visual device using three-color mixing to implement the three-band ratio criterion is presented. Inspection through human vision assisted by an optical device that implements the three-band ratio criterion would offer flexibility and significant cost savings as compared to inspection with a multispectral machine vision system that implements the same criterion. Example applications of this optical three-color mixing technique are given for the inspection of chicken carcasses with various diseases and for apples with fecal contamination. With proper selection of the three narrow wavebands, discrimination by chromaticness that has a direct relation with the three-band ratio can work very well. In particular, compared with the previously presented two-color mixing application, the conditions of chicken carcasses were more easily identified using the three-color mixing application. The novel three-color mixing technique for visual inspection can be implemented on visual devices for a variety of applications, ranging from target detection to food safety inspection.     

锅炉钢结构节点力学特性试验分析

大型电站锅炉钢结构是多层多跨的空间结构,梁、柱的承载形式也是多种多样。所以节点的力学特性对结构的模型建立和结构的应力分析结果起到决定性的作用。节点约束的假设合理与否直接关系到钢结构的安全性和经济性。所以对节点的力学特性的研究,无论从安全性考虑,还是从经济效益上考虑都是具有意义的。     

Highly efficient synthesis of Fe-containing mesoporous materials by using semi-fluorinated surfactant and their high activities in Friedel–Crafts alkylations

Fe-containing mesoporous materials (Fe-JLU-15) with various Si/Fe ratios (47–112) have been successfully synthesized by using semi-fluorinated surfactant of FSO-100 as a template. XRD, N₂ isotherm, and TEM techniques indicate that these samples have worm-like mesostructure with uniform pore size. UV–vis and ESR spectra suggest that Fe species in Fe-JLU-15 are mainly tetrahedrally coordinated. Interestingly, compared with Fe-SBA-15, the efficiency of incorporation of Fe species into Fe-JLU-15 is relatively high. Very importantly, catalytic data in benzylation of aromatic compounds such as benzene, toluene, and ethylbenzene with benzyl chloride shows that Fe-JLU-15 samples are very active and recycle catalysts.

光纤气体传感系统背景噪声的滤除

在光纤气体传感系统中,为提高检测的灵敏度,需要采取措施抑制系统的各类噪声。通过设计低噪声的前置放大器和光源驱动电路可有效地降低系统的噪声;但对于因光路变化和光在传输过程中偏振态发生变化引起的背景噪声的处理一直是光纤气体传感系统测量灵敏度提高的难点。提出一种基于最小二乘拟合的背景噪声滤除算法。利用参考光栅和法布里-珀罗标准具实现对输出信号的光谱重建。在此基础上,利用气体特征吸收峰两边的输出拟合整个输出曲线。将系统的输出与拟合曲线相除,实现系统输出的归一化,有效地滤除了系统的背景噪声,避免了当传感系统背景噪声发生变化时,需要重新采集背景气的繁琐工作,为测量带来方便。
