The Method of Separation of Tongue Coating and Tongue Texture in the Process of Tongue Diagnosis Informatization

应用计算机分析舌像,在舌像信息辅助下推断中医证型的过程中,实现舌质、舌苔区域的自动化分离是前提条件,分离结果直接影响到后续舌质、舌苔颜色分类识别的质量,最终影响证型推断的准确性。在质苔分离实验中采用两种方法,即基于HSV色彩空间的最佳阈值迭代算法和基于彩色特征组合的分割方法,根据两者各自特点,综合叠加运用这两种方法,有效的解决质苔分离问题。The separation of the coating and the texture of the tongue is crucial and prerequisite for the TCM-diagnosing from the information of the tongue which derived from the analysis of the tongue picture with the computer. The qualify of the separation will directly affect the classification and recognition of the color of the tongue coating and tongue texture in the following step, at last, the accuracy of syndrome differentiation. Hence, this article concentrates on analysis of the automatic separation of coating and the texture of the tongue. Two methods are comprehensive applied in the separation,first is Optimal Threshold Iterated Algorithm based on HSV color space, and second is based on the color characteristics.Through comprehensive use of the two methods according to their own characteristics, we achieve the purpose of the perfect separation.国家自然科学基金(编号:60601025);; 卫生部联合基金(编号:WKJ2005-2-001);; 厦门市科技计划(编号:3502Z20055003

厦门同安湾红树林及临近光滩沉积物孔隙水中溶解活性磷和亚铁分布特征的对比分析

为了解红树林与光滩磷、铁地球化学行为的差异,借助薄膜扩散梯度技术（ZrO-Chelex DGT）,对厦门同安湾红树林及临近光滩孔隙水中溶解活性磷（DRP）、Fe2+浓度进行了原位测量,并采集了相应沉积物柱状样进行测定分析。结果表明:（1）Fe2+与DRP呈现较好的线性正相关,说明磷的吸附/解吸与铁氧化还原循环有关;（2）在不同深度,光滩孔隙水中DRP浓度均高于对应深度红树林。在浅层,由于溪水的补给造成光滩的磷富集;在深层,红树植物根部吸收导致磷浓度下降,光滩有机质含量较多,矿化释放DRP使其浓度较高;（3）孔隙水中的Fe2+浓度分布表明,红树林区域随着深度的增加,逐渐由好氧环境进入厌氧环境;而光滩沉积物氧化还原环境可能受到红树林的影响,孔隙水Fe2+在垂向上波动分布。国家自然科学基金项目(41672226; 41372242)~

Rolling contact fatigue investigation and experimental simulation for plastic film used for full - opening and partially - opening automatic ventilation greenhouses

The green house is widely used to add the quality and value of agricultural products. Newly developed full opening type green house has a lot of attracted attention because the roof opens and closes automatically in order to control the inside temperature. However, since the roof opens and closes very often, the cover sheet can be used only for 3-4months. This is because the plastic film is damaged between the support and rolling pipes during opening-closing affected by fatigue and wear. In this study, by using Scanning Electronic Microscope (SEM) and roughness test machine, the damage mechanism is investigated for the several plastic films. Then, FEM analysis is performed to evaluate the mechanical damage of plastic film between the pipes under different conditions and film materials. Also rolling fatigue experiments are performed to investigate the damage under different film materials. Then the results are compared with the FEM analysis. It is found that the thickness reduction of the film obtained under static contact analysis is the most important factor to control the damage of the film

Drag reduction using riblets downstream of a high Reynolds number inclined forward step flow

Micro-riblet is an efficient passive method for controlling turbulent boundary layers, with the potential to reduce frictional drag. In various applications within the transportation industry, flow separation is a prevalent flow phenomenon. However, the precise drag reduction performance of riblets in the presence of flow separation remains unclear. To address this, an inclined forward step model is proposed to investigate the interaction between riblet and upstream flow separation. The large eddy simulation (LES) method is applied to simulate the flow over geometries with different step angles and riblet positions. The results show riblets still reduce wall frictional resistance when subjected to the upstream flow separation. Remarkably, as the angle of the step increases from 0 degrees to 30 degrees, the drag reduction experiences an increment from 9.5% to 12.6%. From a turbulence statistics standpoint, riblets act to suppress the Reynold stress in the near-wall region and dampen ejection motions, thus weakening momentum exchange. Quadrant analysis reveals that with the augmentation of flow separation, the Q2 motion within the flow field intensifies, subsequently enhancing the riblet-induced drag reduction. Moreover, the position of the rib lets has a significant impact on the pressure drag. Riblets close to the point of separation enhance flow separation, altering the surface pressure distribution and thus increasing the resistance. The results reveal that when the riblets are positioned approximately 160 riblet heights away from the step, their effect on the upstream flow separation becomes negligible. The precise performance of riblets under complex flow conditions is important for their practical engineering application
