In order to meet the requirements of users in terms of speed, capacity, storage efficiency, and security, with the goal of improving data redundancy and reducing data storage space, an unbalanced big data compatible cloud storage method based on redundancy elimination technology is proposed. A new big data acquisition platform is designed based on Hadoop and NoSQL technologies. Through this platform, efficient unbalanced data acquisition is realized. The collected data are classified and processed by classifier. The classified unbalanced big data are compressed by Huffman algorithm, and the data security is improved by data encryption. Based on the data processing results, the big data redundancy processing is carried out by using the data deduplication algorithm. The cloud platform is designed to store redundant data in the cloud. The results show that the method in this paper has high data deduplication rate and data deduplication speed rate and low data storage space and effectively reduces the burden of data storage.

Objective. This research was to study the application value of real-time shear wave elastography (SWE) quantitative evaluation based on deep learning (DL) in the diagnosis of chronic kidney disease (CKD) in children. Methods. 60 children with pathological diagnoses of CKD were selected as a CKD group. During the same period, 45 healthy children for physical examination were selected as the control group. The application value of real-time shear-wave elastography based on DL in the evaluation of CKD in children was explored by comparing the differences between the two groups. Results. It was found that the elastic modulus values of the middle and lower parenchyma of the left kidney and right kidney in the case group were (22.02 ± 10.98) kPa and (21.99 ± 11.87) kPa, respectively, which were substantially higher compared with (4.61 ± 0.47) kPa and (4.50 ± 0.59) kPa in the control group. Young’s modulus (YM) of the middle and lower parenchyma of the left kidney in patients with CKD stages 3 to 5 was 13.27 ± 0.83, 24.21 ± 5.69, and 31.67 ± 3.82, respectively, and that of the right kidney was 17.26 ± 0.98, 26.76 ± 7.22, and 32.37 ± 4.27, respectively, and the difference was significant ( P  < 0.05). In patients with moderate and severe CKD, the YM values of the middle and lower parenchyma of the left kidney were 17.27 ± 0.83, 27.93 ± 6.49, and those of the right kidney were 17.26 ± 0.98, 29.56 ± 6.49, respectively, and the difference was statistically significant ( P  < 0.05). The serum creatinine (Scr) of the CKD group was substantially higher than that of the control group, and the estimated glomerular filtration rate (eGFR) level of the former was lower than that of the latter. However, there was no statistical difference between the YM values of the middle and lower parts of the left and right kidneys of the CKD group and the control group. Conclusion. The DL-based SWE is a new noninvasive, real-time, and quantitative detection method, which can effectively evaluate the stiffness of the kidney and help to better detect the progress of CKD as a clinical reference.
目标。本研究旨在探讨基于深度学习(DL)的实时横波弹性成像(SWE)定量评估在儿童慢性肾脏疾病(CKD)诊断中的应用价值。方法:选择病理诊断为CKD的儿童60例作为CKD组。同期选取健康儿童体检45例作为对照组。通过比较两组间的差异,探讨基于DL的实时剪切波弹性成像在儿童CKD评估中的应用价值。结果。结果发现,病例组左肾和右肾中下实质弹性模量分别为(22.02±10.98)kPa和(21.99±11.87)kPa,明显高于对照组的(4.61±0.47)kPa和(4.50±0.59)kPa。CKD 3 ~ 5期患者左肾中下实质杨氏模量(YM)分别为13.27±0.83、24.21±5.69、31.67±3.82,右肾杨氏模量分别为17.26±0.98、26.76±7.22、32.37±4.27,差异有统计学意义(P < 0.05)。中重度CKD患者左肾中下实质YM值分别为17.27±0.83、27.93±6.49,右肾中下实质YM值分别为17.26±0.98、29.56±6.49,差异有统计学意义(P < 0.05)。CKD组血清肌酐(Scr)显著高于对照组,且前者估算的肾小球滤过率(eGFR)水平低于后者。而CKD组左、右肾中、下段YM值与对照组比较,差异无统计学意义。结论。基于dl的SWE是一种新的无创、实时、定量的检测方法,可以有效地评估肾脏的硬度,有助于更好地检测CKD的进展,作为临床参考。

Several unexpected behaviors may occur during actual treatment of clinical pathways, which will have negative impact on the implementation and the future work. To increase the performance of current deviation detection algorithms, a method is presented according to business alignment, which can effectively detect the anomaly in the implementation of the clinical pathways, provide judgment basis for the intervention in the process of the clinical pathway implementation, and play a crucial role in improving the clinical pathways. Firstly, the noise in diagnosis and treatment logs of clinical pathways will be removed. Then, the synchronous composition model is constructed to embody the deviations between the actual process and the theoretical model. Finally, A ∗ algorithm is selected to search for optimal alignment. A clinical pathway for ST-Elevation Myocardial Infarction (STEMI) under COVID-19 is used as a case study, and the superiority and effectiveness of this method in deviation detection are illustrated in the result of experiments.

This study was to analyze the application value of a reconstruction algorithm in CT images of patients with coronary heart disease and analyze the correlation between epicardial fat volume and coronary heart disease. An optimized reconstruction algorithm was constructed based on compressed sensing theory in this study. Then, the optimized algorithm was applied to the image reconstruction of multislice spiral CT image data after testing its sensitivity, accuracy, and specificity. 60 patients with suspected angina pectoris were divided into lesion group (40 cases) and normal group (20 cases) according to whether there were coronary atherosclerotic plaques in cardiac vessels. The results showed that the sensitivity, specificity, and accuracy of the optimized reconstruction algorithm were 91.78%, 84.27%, and 95.32%, and the running time was (12.18 ± 2.49) s. The CT value of the liver and the CT ratio of the liver and spleen in the lesion group were (53.81 ± 5.91) and (3.88 ± 0.67), respectively. There was no significant difference between the two groups ( P > 0.05 ). The body mass index and epicardial fat volume in the lesion group were (31.93 ± 4.54) kg/m2 and (120.09 ± 22.01) cm3, respectively. The body mass index and fat volume in the lesion group were significantly higher than those in the normal group ( P < 0.05 ). The epicardial fat constitution increased with the increase of the number of coronary arteries involved, and there was a positive correlation between them. Among patients with different coronary atherosclerotic plaques, the epicardial fat volume in patients with mixed plaques was the largest ( P < 0.05 ). In summary, optimizing CT images under compressed a sensing reconstruction algorithm could effectively improve the diagnostic accuracy of doctors. Epicardial fat volume was positively correlated with coronary heart disease. Epicardial fat volume could be used as one of the important indexes to predict coronary heart disease.
本研究旨在分析一种重构算法在冠心病患者CT图像中的应用价值,分析心外膜脂肪体积与冠心病的相关性。本研究基于压缩感知理论构建了一种优化的重构算法。然后,将优化后的算法应用于多层螺旋CT图像数据的图像重建中,测试其灵敏度、准确性和特异性。将60例疑似心绞痛患者根据是否有冠状动脉粥样硬化斑块分为病变组(40例)和正常组(20例)。结果表明,优化后的重建算法的敏感性、特异性和准确性分别为91.78%、84.27%和95.32%,运行时间为(12.18±2.49)s。病变组肝脏CT值和肝脾CT比值分别为(53.81±5.91)和(3.88±0.67)。两组间差异无统计学意义(P > 0.05)。病变组体重指数为(31.93±4.54)kg/m2,心外膜脂肪体积为(120.09±22.01)cm3。病变组体重指数、脂肪体积明显高于正常组(P < 0.05)。心外膜脂肪构成随冠状动脉累及数的增加而增加,两者呈正相关。不同冠状动脉粥样硬化斑块患者中,混合性斑块患者心外膜脂肪体积最大(P < 0.05)。综上所述,利用感知重构算法对压缩后的CT图像进行优化,可以有效提高医生的诊断准确率。心外膜脂肪量与冠心病正相关。心外膜脂肪体积可作为预测冠心病的重要指标之一。

Decision support technology has become a key link in modern information strategy. With the deepening of research, introduced expert systems have been introduced into decision support systems. In this way, decision support systems gradually become more uncertain and capable of handling uncertainties. The development direction of decision support system is typically based on qualitative analysis. Intelligent decision support system is a system that combines decision support system with artificial intelligence technology. This study attempts to assess in an innovative way the relationship between financing constraints, entrepreneurship, and agricultural firms. The most recently proposed intelligent decision support system, AI-assisted Intelligent Decision Support System (AIIDSS), is used to predict the impact of entrepreneurship on corporate performance. The paper constructs an entrepreneurship index from five aspects: innovation, competitiveness, human capital accumulation, management capability, and adventurous spirit. The method intends to construct the Kaplan–Zingales (KZ) index to evaluate financing constraints. Through an empirical study, it was found that entrepreneurship can significantly promote the growth of listed agricultural companies. The study can drastically reduce the difficulties involved in financing constraints normally faced by agricultural companies. The impact paths include increasing agricultural company operating cash flow, improving stock liquidity, and increasing debt financing. The research suggests that if listed agricultural companies are to improve financing constraints, entrepreneurs must improve their own competitiveness and management capabilities. This will help in reasonably controlling research and development investment besides the impulse to take risks. As the growth of an enterprise relies on considering the determinants of financing constraints, this research provides an effective investigation technique. Moreover, the findings of the study will help entrepreneurs, particularly agricultural companies, to bear most of the risks and to avail most of the opportunities.
决策支持技术已成为现代信息战略的关键环节。随着研究的深入,引入专家系统已被引入到决策支持系统中。这样,决策支持系统的不确定性逐渐增强,处理不确定性的能力也逐渐增强。决策支持系统的发展方向通常是基于定性分析。智能决策支持系统是将决策支持系统与人工智能技术相结合的系统。本研究试图以一种创新的方式评估融资约束、创业精神和农业企业之间的关系。最近提出的智能决策支持系统,人工智能辅助智能决策支持系统(AIIDSS),用于预测创业对公司绩效的影响。本文从创新、竞争力、人力资本积累、管理能力和冒险精神五个方面构建了创业指数。该方法拟构建Kaplan-Zingales (KZ)指数来评价融资约束。通过实证研究发现,创业精神对农业上市公司的成长性有显著的促进作用。这项研究可以大大减少农业公司通常面临的融资限制所涉及的困难。影响路径包括增加农业公司经营性现金流、改善股票流动性和增加债务融资。研究表明,农业上市公司要改善融资约束,企业家必须提高自身的竞争力和管理能力。这将有助于合理控制研发投资,而不是冒险的冲动。由于企业的成长依赖于考虑融资约束的决定因素,本研究提供了一种有效的调查技术。此外,这项研究的结果将有助于企业家,特别是农业公司,承担大部分风险并利用大部分机会。

In order to obtain the complete equilibrium state of rural financial market and ensure the stable development of rural financial consumer market, this paper introduces CGE model and analyzes the dynamic trust mechanism of individual consumers in rural financial market. In this paper, the single variable evolutionary fuzzy clustering algorithm is used to analyze the orthogonal eigenvector solutions of individual consumers; the big data of individual consumers under the mode of perceived trust is automatically clustered, so as to obtain the fuzzy analogy function of individual consumers in the rural financial market; and finally the prediction value of consumer trust is obtained. The results show that trust, customer satisfaction, and service quality are positively correlated. Under the same sample expectation constraints, the dynamic CGE model is more robust, and the individual consumer trust mechanism of rural financial market in the study area has higher advantages.

The traditional centralized storage of traditional electronic medical records (EMRs) faces problems like data leakage, data loss, and EMR misplacement. The current protection measures for patients’ privacy in EMRs cannot withstand the fast-developing password cracking technologies and frequency cyberattacks. This paper intends to innovate the information sharing and privacy protection of electronic nursing records (ENRs) management system. Specifically, the signature interception technology was introduced to EMRs, the different phases of certificateless signature interception scheme were depicted, and the validation procedures of the scheme were designed. Then, the six phases of ENR information sharing protocol based on alliance blockchain were described in detail. Finally, an end-to-end memory neural network was constructed for ENR classification. The proposed management scheme was proved effective through experiments.

The world is undergoing great changes that have not been seen at present; colleges and universities can only adapt to social development with a more active and open attitude. Meanwhile, colleges and universities strive to obtain more social resources during the process of gradually embedding social funds into the operation system of universities. In such a backdrop, we establish an optimization model for university running efficiency under limited funds, where the objective function is quadratic and restraint condition is linear. With the help of optimization theory, we have obtained the optimal solution of this optimization model and put forward corresponding suggestions to improve the running efficiency of higher education.

Considering task dependencies, the balancing of the Internet of Health Things (IoHT) scheduling is considered important to reduce the make span rate. In this paper, we developed a smart model approach for the best task schedule of Hybrid Moth Flame Optimization (HMFO) for cloud computing integrated in the IoHT environment over e-healthcare systems. The HMFO guarantees uniform resource assignment and enhanced quality of services (QoS). The model is trained with the Google cluster dataset such that it learns the instances of how a job is scheduled in cloud and the trained HMFO model is used to schedule the jobs in real time. The simulation is conducted on a CloudSim environment to test the scheduling efficacy of the model in hybrid cloud environment. The parameters used by this method for the performance assessment include the use of resources, response time, and energy utilization. In terms of response time, average run time, and lower costs, the hybrid HMFO approach has offered increased response rate with reduced cost and run time than other methods.

Animation Design Based on 3D Visual Communication Technology 基于三维视觉传达技术的动画设计
Pub Date : 2022-01-05 DOI: 10.1155/2022/6461538
Feng Shan, Youya Wang
The depth synthesis of image texture is neglected in the current image visual communication technology, which leads to the poor visual effect. Therefore, the design method of film and TV animation based on 3D visual communication technology is proposed. Collect film and television animation videos through 3D visual communication content production, server processing, and client processing. Through stitching, projection mapping, and animation video image frame texture synthesis, 3D vision conveys animation video image projection. In order to ensure the continuous variation of scaling factors between adjacent triangles of animation and video images, the scaling factor field is constructed. Deep learning is used to extract the deep features and to reconstruct the multiframe animated and animated video images based on visual communication. Based on this, the frame feature of video image under gray projection is identified and extracted, and the animation design based on 3D visual communication technology is completed. Experimental results show that the proposed method can enhance the visual transmission of animation video images significantly and can achieve high-precision reconstruction of video images in a short time.
目前的图像视觉传达技术忽略了图像纹理的深度合成,导致视觉效果不佳。因此,提出了基于三维视觉传达技术的影视动画设计方法。通过3D视觉传播内容制作、服务器端处理、客户端处理,收集影视动画视频。通过拼接、投影映射和动画视频图像帧纹理合成,3D视觉传达动画视频图像投影。为了保证动画和视频图像相邻三角形之间比例因子的连续变化,构造了比例因子场。利用深度学习提取深度特征,并基于视觉传达重建多帧动画和动画视频图像。在此基础上,对灰度投影下视频图像的帧特征进行识别和提取,完成了基于三维视觉传达技术的动画设计。实验结果表明,该方法能显著增强动画视频图像的视觉传输能力,并能在短时间内实现视频图像的高精度重建。
