Mycoremedial Approach for Biodegradation of Textile Dyes 生物降解纺织品染料的菌核疗法
Sakshi Suman, Yamini Agrawal, Aarti Yadav, Nitin Chauhan
Mycoremediation, a form of bioremediation facilitated by fungi, has been employed for the biodegradation of azo dyes, including congo red, acid red, and basic blue. In this study, four fungal isolates, namely Aspergillus niger, Aspergillus piperis, Penicillium oxalicum, and Penicillium chrysogenum, obtained from dye effluent were used. Four biodegradation methods were selected, including solid media dye accumulation, liquid media methods under stationary and shaking conditions at 28°C, and biosorption using dead biomass. For the first time, we report the involvement of the isolated fungal species A. piperis, derived from textile effluent, in the biodegradation of textile dyes. Comparative spectrophotometric analysis revealed more than 90% of dye decolourization in the fungus-inoculated medium supplemented with dyes, compared to control. Higher percentage of decolorization were obtained under shaking conditions compared to the stationary method. Dead fungal biomass exhibited effective dye absorption, resulting in a noticeable color change during dye degradation. The seed germination bioassay revealed that treated dye solutions promoted germination; however, untreated inhibited it. Further, untreated dye effluent hindered microbial growth. The excellent performance of A. piperis in the biodegradation of textile azo dyes with diverse chemical structures highlights and reinforces the bioremediation potential of these fungi for environmental decontamination.
菌核修复是一种由真菌促进的生物修复形式,已被用于对包括刚果红、酸性红和碱性蓝在内的偶氮染料进行生物降解。本研究使用了从染料废水中分离的四种真菌,即黑曲霉、哌啶曲霉、草青霉和蛹青霉。我们选择了四种生物降解方法,包括固体培养基染料累积法、28°C 固定和振荡条件下的液体培养基法以及利用死亡生物质的生物吸附法。我们首次报道了从纺织污水中分离出的真菌 A. piperis 参与纺织染料的生物降解。分光光度法比较分析表明,与对照组相比,在真菌接种的培养基中,染料脱色率超过 90%。与固定法相比,摇动法的脱色率更高。死亡的真菌生物量能有效吸收染料,从而在染料降解过程中产生明显的颜色变化。种子萌发生物测定显示,处理过的染料溶液能促进种子萌发;而未经处理的染料溶液则会抑制种子萌发。此外,未经处理的染料废水阻碍了微生物的生长。A. piperis 在生物降解具有不同化学结构的纺织品偶氮染料方面的优异表现,凸显并加强了这些真菌在环境净化方面的生物修复潜力。

Effect of Input Layer Signal Polarization on the Dynamics of Optical Neural Networks 输入层信号极化对光神经网络动力学的影响
None Mariam R. Dhyaa, None Ayser A. Hemed
The polarization encoding-based optical validation and security verification approach is provided in this paper. This technique involves simulating information optically and bonding it to a polarization-encoded mask, such as a biological order or a reaction. The linear polarizers that make up the polarization-encoded mask are positioned at random. The polarization-encoded signal is the name given to this composite signal. In this simulation study, a primary optical neural network adapting a light brain technology is proposed theoretically based on a feed-forward model. Calibration of the nonlinear behavior in such a network is assumed by a semiconductor laser of the Distributed Feedback (DFB) type. Four laser networks are constructed as three influencers, followed by one embedding laser followers. Each of the influencer’s lasers has a different wavelength frequency and polarization (30-60–90) degree, respectively, and then combines the signal with WDM for the last laser. With each value, from the last values, of the polarization effect after this effect, the results indicated that these values would present the greatest weight of spikes and chaotic behavior for the uploaded virtual message.
提出了一种基于偏振编码的光学验证和安全验证方法。该技术涉及光学模拟信息,并将其与偏振编码掩模结合,例如生物顺序或反应。构成偏振编码掩模的线性偏振器是随机定位的。偏振编码信号就是这个复合信号的名称。在仿真研究中,基于前馈模型,从理论上提出了一种适应光脑技术的初级光神经网络。在这种网络中,非线性行为的校准由分布式反馈(DFB)型半导体激光器承担。构建了四个激光网络,分别作为三个影响者和一个嵌入的激光追随者。每个影响者的激光器分别具有不同的波长频率和偏振度(30-60-90),然后将信号与波分复用相结合,形成最后一个激光器。对于该效应后极化效应的每个值,从上一个值来看,结果表明这些值对上传的虚拟消息表示最大的峰值权重和混沌行为。

Simulation Studies of Three-Way Unbalanced Design on Fixed, Random, and Mixed Model 固定、随机和混合模型下的三向不平衡设计仿真研究
None Amalia Nailul Husna, None Muhammad Nur Aidi, None Indahwati, None Fitrah Ernawati
Analysis of Variance (ANOVA) is a statistical technique used to compare means from various samples. Generally, a balanced design is used in ANOVA, but in some conditions, an unbalanced design can happen when the sample size is different in each treatment. This design will have the calculation of the F-test is different from usual for fixed, random, and mixed models. In this research, a simulation study will be carried out to see the differences in the results of the F-test decision in a three-way ANOVA with an unbalanced design based on a fixed, random, and mixed model. Simulation data is generated based on several scenarios, small sample size and large sample size, e~Normal (0,1) and e~Gamma (2,3), and applied to 8 models, that combine fixed effects and random effects in a 3-factor design. The simulation shows that sample size, error distribution, and the used model can affect F-test decisions. Designs with large sample sizes and e~Normal (0,1) produce more significant F-test decisions than small sample sizes and e~Gamma (2,3), and model 1 or the fixed model has more significant F-test decisions than other models in each scenario.
方差分析(ANOVA)是一种用于比较不同样本均值的统计技术。一般来说,在方差分析中使用平衡设计,但在某些情况下,当每次处理的样本量不同时,可能会出现不平衡设计。这种设计将有不同于通常的固定、随机和混合模型的f检验计算。在本研究中,将进行模拟研究,以了解基于固定,随机和混合模型的不平衡设计的三向方差分析中f检验决策结果的差异。模拟数据基于小样本量和大样本量、e~Normal(0,1)和e~Gamma(2,3)几种场景生成,应用于固定效应和随机效应相结合的8个模型,采用3因素设计。仿真结果表明,样本量、误差分布和使用的模型都会影响f检验的决策。具有大样本量和e~Normal(0,1)的设计比具有小样本量和e~Gamma(2,3)的设计产生更显著的f检验决策,并且模型1或固定模型在每个场景中比其他模型具有更显著的f检验决策。

People Identification Through Facial Recognition and Anti-Spoofing Using Deep Learning 人脸识别与深度学习反欺骗识别
None Fathima Jameera. B, None G. Suresh, None S. Hemalatha, None S. Vilma Veronica
This research effort uses cutting-edge anti-spoofing techniques in conjunction with deep learning approaches to address the issue of spoofing assaults on facial recognition systems. A diversified dataset containing real facial photos and several spoofing attack scenarios is compiled as the project's first step. Then, data pretreatment methods are used to guarantee data consistency and the best model performance. The research makes use of MobileNet and VGG-16, two well-known deep-learning architectures, to build reliable facial recognition models. A thorough evaluation using well-established metrics including classification reports, accuracy scores, and confusion matrices is undertaken after thorough training and validation. It's significant because this research incorporates real-time anti-spoofing capabilities, which go beyond traditional facial recognition jobs. Webcam functionality is added to the deployed models to assess real-time images in comparison to reference passport-size photos. Dynamically shifting boundary box colors—blue for real faces and red for detected fake images—indicate the anti-spoofing technology. The project's conclusion contains a thorough comparison of the MobileNet and VGG-16 models that identifies and compares each model's advantages and disadvantages. Real-time demos also highlight the anti-spoofing methodology's effectiveness in practice.
这项研究工作将尖端的反欺骗技术与深度学习方法相结合,以解决面部识别系统的欺骗攻击问题。该项目的第一步是编译包含真实面部照片和几种欺骗攻击场景的多样化数据集。然后,采用数据预处理方法保证数据一致性和最佳模型性能。本研究利用MobileNet和VGG-16这两种知名的深度学习架构,构建可靠的面部识别模型。彻底的评估使用完善的指标,包括分类报告,准确性分数,和混淆矩阵进行彻底的培训和验证后。这项研究意义重大,因为它结合了实时反欺骗能力,超越了传统的面部识别工作。网络摄像头功能被添加到部署的模型中,以评估与参考护照大小的照片相比的实时图像。动态变化的边界框颜色——真实人脸为蓝色,检测到的假图像为红色——表明了抗欺骗技术。该项目的结论包含了对MobileNet和VGG-16模型的全面比较,确定并比较了每种模型的优缺点。实时演示也突出了反欺骗方法在实践中的有效性。

Investigation of Erosion Effect on Surface of Basalt Fibre Reinforced Polymer Composites 玄武岩纤维增强聚合物复合材料表面侵蚀效应研究
None Sunil Nayak, None M. Prasanna Kumar
In the present study the erosion behavior of basalt fibre reinforced composite was studied. Slurry pot erosion test were conducted on the composite samples with 30%, 40% 50% and 60% reinforcement. Slurry concentration, speed and contact angle were considered as the parameters. The sand particles from the range of 212, 425 and 600µm were suspended in the water. The results revels that the slurry erosion was found to be increased with slurry concentration and the turning speed. The impact angle with 900 has the major influence on the erosion. The highest mass loss due to erosion is found in the sample with 30% reinforcement and the minimal mass loss due to erosion is found in the sample with 60% reinforcement.
本文对玄武岩纤维增强复合材料的侵蚀性能进行了研究。分别对30%、40%、50%和60%配筋的复合材料试样进行了砂浆罐冲试验。考虑了料浆浓度、速度和接触角等参数。212、425和600µm范围内的沙粒悬浮在水中。结果表明,浆液侵蚀随浆液浓度和转速的增加而增大。900的冲击角对冲蚀影响最大。由于侵蚀造成的最大质量损失出现在补强率为30%的样品中,而由于侵蚀造成的最小质量损失出现在补强率为60%的样品中。
