Brain tumor detection and diagnosis using ANFIS classifier

In this article, the segmented brain tumor region is diagnosed into mild, moderate, and severe case based on the presence of tumor cells in the brain components such as Gray Matter (GM), White Matter (WM), and cerebrospinal fluid (CSF). The modified spatial fuzzy c mean algorithm is used to segment brain tissues. The feature Local binary pattern is extracted from segmented tissues, which is trained and classified by ANFIS Classifier. The performance of the proposed brain tissues segmentation system is analyzed in terms of sensitivity, specificity, and accuracy with respect to manually segmented ground truth images. The severity of brain tumor is diagnosed into mild case if the segmented brain tumor is present in the grey matter. The severity of brain tumor is diagnosed into moderate case if the segmented brain tumor is present in the WM. The severity of brain tumor is diagnosed into severe case if the segmented brain tumor is present in the CSF region. The immediate surgery is required for severe case and medical treatment is preferred for mild and moderate case.     

Tooth—A natural biocomposite

The inorganic content of human tooth is predominantly hydroxyapatite. The content varies in enamel and dentin. A reversible thermal transformation at 157 C is observed and has correspondence in the dielectric measurements. The dental decay is related to the piezoelectric property of tooth, which is similar to a polar glassceramic. The toughness of tooth is higher than hotpressed hydroxyapatite and owes it to the microstructure signifying the importance of a weak, pliable interface. The hardness is graded, higher for enamel in the crown and very much lower for dentin, to suit their function and environment. The relevance of biomimics in designing materials for advanced performance is discussed.

The impurity mechanism proposed earlier is used to interpret the magnetic properties of hightemperature superconductors.

The irreversibility line is obtained and its new interpretation as the line of thresholds of appearance of infinite nonsuperconductive cluster is given. The relaxation time of the magnetic susceptibility in alternating magnetic fields is calculated. The decrease of the Meissner fraction with increase in magnetic field and decrease in doping, and other magnetic properties are explained.     

基于生成对抗网络的行人异常行为图像去模糊算法研究

为解决在行为异常检测中遇到的运动模糊问题,提出一种基于DeblurGAN改进的快速去运动模糊算法。使用3个3 3的卷积替换原生成器中的7 7的卷积,并舍弃原算法上采样时使用的转置卷积,对需要上采样的特征图进行双线性插值。将原算法生成器结构中的残差单元替换成密集残差块(RRDB),然后将得到的残差特征缩放到0 1之间的值,避免训练不稳定。在原生成器的损失函数中添加梯度图像的L1损失,增加图像的边缘信息使重建后的图像边缘更明显,克服了DeblurGAN重建图像边缘细节不够清晰的缺陷。经实验验证,并和文献[14]、文献[18]进行比较,结果显示：优化后的模型与DeblurGAN相比,峰值信噪比提高0.94,结构相似度和速度相当,并解决了重建后图像棋盘格子的问题,细节边缘更加突出,模型性能优于相关算法。     

The Kinetics of Oxidation of Zirconium Iodide in an Air-Argon Mixture at High Temperatures

The thermogravimetric method is used to investigate the kinetics of oxidation of zirconium iodide in an air-argon mixture in the temperature range from 1380 to 1968 K. The high-frequency induction heating is used to attain high temperatures. The temperature is measured by a precision optical monochromatic pyrometer using a black-body model located in the sample being investigated. The increment of sample mass is measured continuously using a spring balance. One sample is investigated, whose temperature is successively increased in jumps with stops on isotherms. The transition of tetragonal modification of oxide film to a mixture of tetragonal and cubic modifications is registered at 1745 K. The obtained results are used to calculate the Arrhenius equation for tetragonal modification of oxide film in the range from 1380 to 1730 K. The activation energy is 180.7 kJ/mol. The obtained results are compared to available literature data.

Texture Evolution in Severe Plastic Deformation by Equal Channel Angular Extrusion

The majority of the techniques of severe plastic deformation calls for simple shear deformation mode. This is why a special interest is given in this paper to textures that develop in simple shear. The evolution of texture in Equal Channel Angular Extrusion (ECAE) is also discussed in detail. The classical “simple shear model” of ECAE is examined as well as a new, more precise flow field which uses an analytical flow function. The proposed function is inspired from finite element calculations. The velocity gradient that follows from the analysis is incorporated into the self consistent viscoplastic polycrystal code. The evolution of deformation texture is predicted up to two passes in the A‐route ECAE deformation of copper polycrystal when the extrusion angle is 90°.
