The most interested point is to find the natural frequency of a nano-composites plate and its study analytically and numerically by ANSYS software. Very good mechanical properties of carbon nanotubes give them importance for reinforcing the composite plate to get acceptable property for a new material. The Polyprime EP epoxy as a matrix, which is strengthened via Multi-Walled Carbon Nanotubes (MWCNTs), has been analyzed. Three loading ratios (0.1, 0.5 and 1 wt.%) of MWCNTs have been added to epoxy using a magnetic stirrer, and then hardener was added and blended with them. Tensile tests were conducted upon unfilled, MWCNT-filled epoxy to find the materials' mechanical properties. A CNC machine was used to cut all samples. Scanning Electron Microscopy (SEM) was utilized to obtain the nanotubes' dispersal status into the base matrix. Higher Order Shear Deformation Plate Theory (HSDT) and ANSYS software were employed for finding the natural frequency for the three loading ratios. The results of tensile tests manifested an enhancement in the Young’s modulus for higher supplement percentages of MWCNT. And, the maximum tensile strength was obtained at 0.5 wt.% of MWCNT with the ratio 66.7%. The SEM images explicated that the sample of 0.1 wt.% MWCNT possesses less voids in comparison with the other samples. The effect of increasing loading ratio from 0.1 wt.% to 0.5 wt.% increased the frequency by 5.9%.
利用ANSYS软件对纳米复合材料板的固有频率进行分析和数值研究是本文研究的重点。碳纳米管具有良好的力学性能,这对增强复合材料具有重要意义。研究了以多壁碳纳米管(MWCNTs)为强化材料的Polyprime EP环氧树脂基体。采用磁力搅拌器将三种载荷比(0.1、0.5和1wt .%)的MWCNTs加入到环氧树脂中,然后加入硬化剂并与之混合。对未填充和mwcnt填充的环氧树脂进行拉伸试验,以确定材料的力学性能。使用数控机床切割所有样品。利用扫描电镜(SEM)观察了纳米管在基体中的分散状态。采用高阶剪切变形板理论(HSDT)和ANSYS软件计算了三种加载比下的固有频率。拉伸试验的结果表明,在杨氏模量的提高,较高的MWCNT补充百分比。当MWCNT含量为0.5 wt.%时,材料的抗拉强度达到最大值,比例为66.7%。SEM图像表明,与其他样品相比,0.1 wt.%的MWCNT样品具有更少的空隙。加载比从0.1 wt.%提高到0.5 wt.%的效果使频率提高了5.9%。

Developing a whole kidney model is important for effective diagnostic procedures and treating kidney diseases. The modeling of a multi-nephron network aids in developing the whole kidney model. The key aspect of any nephron model is understanding the pressure dynamics. The governing equations for pressure dynamics in the kidney depend on the number of nephrons and their interactions. There are mathematical models to analyze the local and global behaviors of single and coupled nephrons. It is difficult to formulate governing equations for a whole kidney model. This necessitates the development of simulation models. Even the simulation models have only been developed for 72 nephrons. The complexity is involved in incorporating both local and global behaviors of nephrons. In this paper, a cellular automata (CA) framework has been proposed to study the global behavior of nephrons. The advantage of the proposed CA framework is its scalability and its ability to capture global dynamics without formulating the corresponding governing equations. The limitation of the CA framework is its inability to compare point-to-point local behavior. But the clinical findings suggest that global behavior gives significant information about the kidney. We have developed CA rules for 8-nephron, 16-nephron, 72-nephron and 100-nephron network models considering both rigid and compliance tubules. The CA rules with various initialization schemes produce different evolutionary patterns similar to the emergent dynamical behavior of nephrons obtained from experimental and numerical findings. Evolutionary patterns of the CA framework are related to normotensive and hypertensive pressure dynamics. The in-phase and out-of-phase synchronizations have also been observed in the CA evolutionary patterns. The irregular rhythm of the cardiovascular system may give rise to shock waves in the pressure dynamics of the kidney. This behavior has also been observed in the proposed CA framework.
建立全肾模型对肾脏疾病的有效诊断和治疗具有重要意义。多肾元网络的建模有助于整个肾脏模型的建立。任何肾元模型的关键是理解压力动态。肾脏压力动力学的控制方程取决于肾单位的数量及其相互作用。有数学模型来分析单个和耦合肾元的局部和全局行为。对于整个肾脏模型,很难建立控制方程。这就需要开发仿真模型。即使是模拟模型也只开发了72个肾元。这种复杂性涉及到肾元的局部和全局行为。本文提出了一个元胞自动机(CA)框架来研究肾元的整体行为。所提出的CA框架的优点是其可扩展性和无需制定相应的控制方程即可捕获全局动态的能力。CA框架的局限性在于它无法比较点对点的本地行为。但临床研究结果表明,整体行为提供了有关肾脏的重要信息。我们已经开发了考虑刚性和顺应性小管的8肾元、16肾元、72肾元和100肾元网络模型的CA规则。不同初始化方案下的CA规则产生了不同的演化模式,这与实验和数值结果得出的肾元的紧急动力学行为相似。CA框架的进化模式与正常血压和高血压动态有关。在CA演化模式中也观察到相内同步和相外同步。心血管系统的不规则节律可能在肾脏压力动力学中引起冲击波。在提议的CA框架中也观察到了这种行为。

Utilities have been forced to raise the overall efficiency towards a better position in radial distribution systems (DS). From the literature, it has been proved that reactive power compensation performs well in minimizing the PLoss and enhancing the bus voltage profile within the permissible range in radial DSs. This work presents the salp swarm algorithm (SSA) to solve the problem efficiently. The merit of this technique is that it can offer a global or near-global optimum for capacitor siting and sizing. The main intention of this study is to obtain annual financial benefits using the placement and sizing of capacitors optimally. This can however be achieved by minimizing the objective function composed of cost-based power loss and capacitor cost on radial DS considering three different load levels. The proposed technique has been tested on standard IEEE 69 and modified 12 bus systems. Computational results are compared with the results obtained by the previous published work and proved that SSA can minimize the PLoss more effectively thereby financial benefit.
公用事业公司被迫在径向配电系统(DS)中提高整体效率。从文献中可以证明,无功功率补偿在减小漏损和提高径向DSs的母线电压分布在允许范围内有很好的效果。本文提出了salp swarm算法(SSA)来有效地解决这一问题。这种技术的优点是它可以为电容器的选址和尺寸提供全局或接近全局的最佳选择。本研究的主要目的是通过优化电容器的布局和尺寸来获得年度经济效益。然而,这可以通过最小化目标函数来实现,该目标函数由基于成本的功率损耗和考虑三种不同负载水平的径向DS上的电容器成本组成。该技术已在IEEE 69标准和改进的12个总线系统上进行了测试。将计算结果与前人的研究结果进行了比较,证明了SSA能更有效地减小PLoss,从而获得经济效益。

To solve the problem of pesticide misuse in judging common wheat diseases, we propose a wheat disease identification scheme combining the VGG convolutional neural network model with WeChat mini program technology. In the model training process, we continuously adjust the structure of the convolutional neural network VGG-16 to realize the real-time and accurate identification model of wheat disease. Specifically, the model parameters are optimized by locally adjusting the convolution layer of the VGG-16 network to achieve accurate maximization. Through the verification, the best accuracy rate of the wheat disease identification model is 85.1%. The mini program is compiled by the WeChat developer tool, which is developed based on WXML, WXSS and JavaScript. After building the wheat disease identification model, it is deployed on a cloud server that works continuously for working 24 h a day. In addition, the mini program posts HTTPS requests as the function of wheat disease identification. The implementation of this scheme can help users identify different types of wheat diseases and provide corresponding solutions according to the results, which is of great significance in underdeveloped agricultural areas.

The synthesis of precipitated calcium carbonate (PCC) using plant extracts as additives has been developed to modify the morphology, particle size, chemical purity, and stability of PCC to be used for a variety of potential applications. In this study, aloe vera ( Aloe barbadensis Miller ) was used as an additive for the synthesis of PCC. The synthesis of PCC was carried out using a tubular column reactor under the temperatures of 30, 50 and 100℃ and was performed without and with aloe vera extract concentrations of 3, 5, 8 and 10 vol%. Recycled carbon dioxide (CO 2 ) with a flow rate of 1 L/min was used which was obtained from the calcination process. The purity and morphology of synthesized PCC were analyzed using X-ray fluorescence and scanning electron microscope, respectively. The results demonstrated that the increase in the aloe vera concen tration from 3 to 10 vol% produced the aragonite crystals at 100℃. The agglomerated cluster was observed with a rhombohedral shape with 3 and 5 vol% of aloe vera extract under the temperature of 30℃. The obtained PCC yield was 91, 72 and 93% at 30, 50 and 100℃, respectively with 10 vol% of aloe vera extract.
以植物提取物为添加剂合成沉淀碳酸钙(PCC),可以改变PCC的形态、粒度、化学纯度和稳定性,具有多种潜在的应用前景。本研究以芦荟(aloe barbadensis Miller)为添加剂合成PCC。在30、50和100℃的条件下,在不含芦荟提取物和芦荟提取物浓度为3、5、8和10 vol%的条件下,采用管状塔式反应器进行PCC的合成。采用煅烧过程中获得的再生二氧化碳(co2),流量为1l /min。用x射线荧光显微镜和扫描电镜对合成的PCC进行了纯度分析和形貌分析。结果表明,当芦荟浓度从3%增加到10%时,在100℃下产生文石晶体。在30℃的温度下,芦荟提取物含量分别为3和5 vol%,观察到凝集团簇呈菱形。当芦荟提取物含量为10 vol%时,在30、50和100℃条件下PCC的产率分别为91%、72%和93%。

Deployment of CNN on colour fundus images for the automatic detection of glaucoma 在彩色眼底图像上部署CNN自动检测青光眼

Detection of glaucoma has become critical, as it has arisen as the subsequent essential driver of visual impairment, around the world. At present, most of the algorithms in use rely on pre-trained deep neural networks to produce the best results. However, the high computational time and complexity and the need of a large database, make glaucoma-detection arduous and difficult. Keeping these in mind, this paper proposes a new convolutional neural network architecture, in particular, ProspectNet, which has demonstrated to accomplish a better accuracy with lesser computational time and complexity when tested against two pre-trained networks: VGG16 and DenseNet121. The data set is an amalgamation of two publicly available datasets-DRISHTI-GS and Glaucoma Dataset (Kaggle), comprising ocular colour fundus images of glaucomatous as well as normal eyes. ProspectNet has accomplished a normal AUC (area under the curve) as 0.991, specificity, and precision as 0.98. Confusion matrices also plotted to illustrate the new architecture’s efficacy. These outcomes demonstrate that ProspectNet is a hearty option in contrast to other best in class calculations for a medium sized dataset. The paper suggests three distinct structures for glaucoma detection. One advantage of our approach is that no special feature selection, such as detailed measurements of particular traits like the structure of the optic nerve head, is necessary.
青光眼的检测已变得至关重要,因为它已成为世界各地视力损害的后续重要驱动因素。目前,大多数使用的算法依赖于预训练的深度神经网络来产生最佳结果。然而,青光眼检测的计算时间和复杂度较高,且需要庞大的数据库,这使得青光眼检测工作艰巨而困难。考虑到这些,本文提出了一种新的卷积神经网络架构,特别是ProspectNet,在对两个预训练网络(VGG16和DenseNet121)进行测试时,它已经证明可以以更少的计算时间和复杂性实现更好的准确性。该数据集是两个公开可用的数据集- drishti - gs和青光眼数据集(Kaggle)的合并,包括青光眼和正常眼睛的眼底颜色图像。ProspectNet的正常AUC(曲线下面积)为0.991,特异性为0.98,精密度为0.98。还绘制了混淆矩阵来说明新架构的有效性。这些结果表明,对于中等规模的数据集,与其他同类最佳计算相比,ProspectNet是一个不错的选择。本文提出了三种不同的青光眼检测结构。我们的方法的一个优点是不需要特殊的特征选择,比如对视神经头的结构等特定特征的详细测量。

Keeping these in mind, this paper proposes a new convolutional neural network architecture, in particular, ProspectNet, which has demonstrated to accomplish a better accuracy with lesser computational time and complexity when tested against two pre-trained networks: VGG16 and DenseNet121. The data set is an amalgamation of two publicly available datasets-DRISHTI-GS and Glaucoma Dataset (Kaggle), comprising ocular colour fundus images of glaucomatous as well as normal eyes. ProspectNet has accomplished a normal AUC (area under the curve) as 0.991, specificity, and precision as 0.98. Confusion matrices also plotted to illustrate the new architecture’s efficacy. These outcomes demonstrate that ProspectNet is a hearty option in contrast to other best in class calculations for a medium sized dataset. The paper suggests three distinct structures for glaucoma detection. One advantage of our approach is that no special feature selection, such as detailed measurements of particular traits like the structure of the optic nerve head, is necessary.","PeriodicalId":13778,"journal":{"name":"International Journal of Applied Science and Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77015996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
