Digitalization has been on the rise in the professional, educational, commercial, financial, and basically every major relevant field of the world for much of this century. As every institution race towards ensuring an online presence and accessibility, people have become reliant on digital utilities, sometimes more so than their physical versions. Among the many facilities that are being digitalized, one of them is very relevant to students, employees and organizations which handle mass numbers of people, the attendance system. This is one facility that is still plagued by many errors and loopholes despite its recent development. There is a lack of a secure, robust, userfriendly, automated, and live attendance collection system. This research paper aims to capitalize on this problem and provide a possible solution that addresses these issues.Method: Face recognition system is one such model, which is used to detect real-time human faces. These are used to look for front and side-looking faces and detect them using some technique. They are functioned on the basis of different algorithms. One such algorithm is the LBPH algorithm which this research paper will be talking about. It was earlier used only for text-recognition. But with time, it has evolved and now is able to detect faces with the help of some linking algorithms.Results: This research paper helped us to get an overview on how face recognition system which is in every way a robust, secure and contact-less system can be made. Also, how LBPH algorithm best suits in making such model can be seen through this paper.
在本世纪的大部分时间里,数字化在专业、教育、商业、金融以及世界上几乎所有主要相关领域都在兴起。由于每个机构都在竞相确保在线存在和可访问性,人们已经变得依赖数字设施,有时甚至比实体设施更依赖。在许多正在数字化的设施中,其中一个与学生,员工和处理大量人员的组织非常相关,即考勤系统。尽管这是一个最近发展起来的设施,但仍然存在许多错误和漏洞。缺乏一个安全的、健壮的、用户友好的、自动化的、实时的考勤系统。这篇研究论文的目的是利用这个问题,并提供一个可能的解决方案,解决这些问题。方法:人脸识别系统就是这样一个模型,用于实时检测人脸。这些是用来寻找正面和侧面的脸,并使用一些技术来检测它们。它们的功能基于不同的算法。其中一种算法是LBPH算法,这篇研究论文将讨论它。它以前只用于文本识别。但随着时间的推移,它已经进化,现在能够在一些链接算法的帮助下检测人脸。结果:这篇研究论文帮助我们对人脸识别系统如何在各个方面都是一个强大的、安全的、非接触式的系统进行了概述。通过本文可以看出LBPH算法如何最适合于制作这样的模型。

In this work, LRSPR sensor for detection of macro biomolecules in near infrared range is presented. Using a buffer layer of dielectric with low refractive index between the prism and metal, a long-range surface plasmon resonance (LRSPR) biosensor that exhibits large detection accuracy as well as high figure of merit is proposed. Two-dimensional (2D) material graphene is used to attach biomolecules through carbon-carbon pi-stacking forces. First, the theoretical simulations for optimizing the thicknesses of dielectric buffer layer (Cytop) and gold (Au) metal layer has been carried out. Then, performance parameters DA and FOM were analyzed. The highest FOM of 847.4 RIU−1 is accomplished for the proposed LRSPR sensor with the use of 1500nm thickness of Cytop. We believe that the proposed LRSPR sensor with high DA and FOM could provide potential applications in medical and biosensing field.

With the increasing rise in global power demand, it is becoming necessary to integrate renewable energy sources into conventional radial distribution systems (RDS). IEEE 33 bus RDS is considered in this study, with solar PV sources incorporated for power loss reduction, voltage fluctuation, and improve the system efficiency. For the purpose of charging and discharging, some electric vehicles (EV) are incorporated into the test system. The objective of the study is to analyze how EVs and Renewable energy sources (RES) affect the voltage profile in the RDS. As RES is introduced in the test system, the voltage profile is improved. To decrease voltage fluctuations, the usage of the hull moving average (HMA) is recommended, which avoids the lag problem associated with the commonly used moving average approaches. The genetic algorithm (GA) is used to solve the optimization problem accurately. The simulation results show that the suggested strategy is effective at smoothing voltage fluctuations while taking into account EV battery degradation and charging plans.
随着全球电力需求的不断增长,将可再生能源纳入传统的径向配电系统(RDS)已成为必要。本研究考虑IEEE 33总线RDS,加入太阳能光伏电源,以减少功率损耗,降低电压波动,提高系统效率。为了达到充放电的目的,一些电动汽车(EV)被纳入了测试系统。该研究的目的是分析电动汽车和可再生能源(RES)如何影响RDS中的电压分布。在测试系统中引入RES后,电压分布得到了改善。为了减少电压波动,建议使用船体移动平均(HMA),避免了与常用移动平均方法相关的滞后问题。采用遗传算法(GA)精确求解优化问题。仿真结果表明,该策略可以有效地平滑电压波动,同时考虑到电动汽车电池退化和充电计划。

Multilevel inverters are capable of attaining a staircase output voltage waveform with reduced harmonic content. In this paper, cascaded H bridge 5 level and 7 level inverters are simulated in MATLAB/SIMULINK. The power quality analysis has been carried out for both the designs with and without filters. Filters used at the output of the inverters are low pass filters and second order filters. The amount of deviation of output waveforms from the pure sinusoidal waveforms has been measured as total harmonic distortion. Comparison of both the inverter topologies with and without filters has been done on the basis of Total Harmonic Distortion (THD).

In this fast-developing world digital dependency has taken up great heights. With its immense usage comes the concept of revealing false information of an image to feed the dreadful intention which is called nothing but Image Forgery. The duplicated or forged image is operated in a way that detecting the tampered regions can be an exhaustible task. The paper exactly deals with such alterations in the structure of the image. It offers a Hashing technique, which as best described, helps to detect and locate the tampered regions of the image. A comparison of various Hash Functions like MD5 and SHA-2, in particular, is put into effect with its implementation highlighting the desired tampered region of the image which is facilitated by the sliding window approach.

Family physicians rarely see a malignant bone cancer because it is hard to find, and most of the time, bone cancer is benign. It is very time-consuming and complicated for the pathologist to classify Osteosarcoma histopathological images. Typically Osteosarcoma classifies into viable, Non-viable, and Non-tumor classes, but intra-class variation and inter-class similarity are complex tasks. This paper used the Random Forest(RF) machine learning algorithm, which efficiently and accurately classifies Osteosarcoma into Viable, Non-viable, and Non-tumor classes. The Random Forest method gives a classification accuracy of 92.40%, a sensitivity of 85.44%, and specificity 93.38% with AUC=0.95.

A Comparative Analysis of DC - DC Boost Converter Voltages for Renewable Electrolysis 可再生电解用DC - DC升压变换器电压的比较分析

The process that is responsible for changing a particular DC voltage to another DC voltage is termed as DC- to-DC voltage conversion. There are three types of DC-to-DC power converters. They are Buck Converter, Boost Converter and Buck-Boost Converter. Buck converter steps down voltage from its input to its output while a buck-boost converter maintains higher or lower output, which depends on the source voltage. A boost converter is a system where voltage at the output terminal is higher than the source voltage. It is generally referred by the name "step-up" converter because of its source voltage stepping up capability. Since, power must always be conserved; current at the output terminal is lower than the current at the input terminal. Power requirement for the boost converter can be fulfilled using some efficient DC source, such as batteries, PV panels and DC generators. Boost converter finds application in consumer electronics, DC motor drives, photovoltaic systems and so on. This paper presents a detailed analysis of DC-to-DC boost converter voltages for renewable electrolysis. The paper presents two circuit topologies of the boost converter viz. one with transformer and the other without transformer. A comparative analysis of these circuit topologies is done and MATLAB simulation results are obtained. It has been proved that the topology using a voltage-matching transformer of high frequency is better. In the analysis, the topology with transformer is proved better for renewable electrolysis due to its regulated output voltage and ripple-free characteristic.
将一个特定的直流电压转换为另一个直流电压的过程称为DC- DC电压转换。dc - dc电源转换器有三种类型。它们是降压转换器,升压转换器和降压-升压转换器。Buck变换器从输入端降压到输出端,而Buck -boost变换器则根据源电压的不同,保持较高或较低的输出。升压变换器是一种输出端电压高于源电压的系统。由于它具有源电压升压能力,因此通常称为“升压”变换器。因为,权力必须永远被保存;输出端的电流小于输入端的电流。升压变换器的功率需求可以通过一些高效的直流电源来满足,如电池、光伏板和直流发电机。升压变换器在消费电子、直流电机驱动、光伏系统等领域有广泛的应用。本文详细分析了用于可再生电解的dc - dc升压转换器电压。本文介绍了升压变换器的两种电路拓扑结构,即带变压器和不带变压器。对这两种电路拓扑结构进行了对比分析,并给出了MATLAB仿真结果。实验证明,采用高频电压匹配变压器的拓扑结构效果较好。分析表明,带变压器的拓扑结构具有稳压输出和无纹波特性,更适合再生电解。

Information Security is a unified piece of information technology that has emerged as vibrant technology in the last two decades. To manage security, authentication assumes a significant part. Biometric is the physical unique identification as well as authentication for the third party. We have proposed the security model for preventing many attacks so we are used the innermost layer as a 3DES (Triple Encryption standard) cryptography algorithm that is providing 3- key protection as 64-bit and the outermost layer used the MD5 (Message Digest) algorithm. i. e. providing 128-bit protection as well as we is using fingerprint identification as physical security that is used in third-party remote integrity auditing. Remote data integrity auditing is proposed to ensure the uprightness of the information put away in the cloud. Data Storage of cloud services has expanded paces of acknowledgment because of their adaptability and the worry of the security and privacy levels. The large number of integrity and security issues that arise depends on the difference between the customer and the service provider in the sense of an external auditor. The remote data integrity auditing is at this point prepared to be viably executed. In the meantime, the proposed scheme is depending on identity-based cryptography, which works on the convoluted testament of the executives. The safety investigation and the exhibition assessment show that the planned property is safe and productive.
信息安全是一种统一的信息技术,在过去的二十年里,它已经成为一种充满活力的技术。为了管理安全性,身份验证扮演了重要的角色。生物特征是对第三方的物理唯一识别和认证。我们提出了防止许多攻击的安全模型,因此我们使用最内层作为3DES(三重加密标准)加密算法,该算法提供64位的3个密钥保护,最外层使用MD5(消息摘要)算法。即提供128位保护,我们还使用指纹识别作为第三方远程完整性审计中使用的物理安全。为了保证存储在云中的信息的正确性,提出了远程数据完整性审计。云服务的数据存储由于其适应性和对安全和隐私级别的担忧,扩大了识别的步伐。在外部审计员的意义上,出现的大量完整性和安全性问题取决于客户和服务提供者之间的差异。此时,远程数据完整性审计已准备好执行。与此同时,提议的方案依赖于基于身份的密码学,它适用于高管的复杂遗嘱。安全调查和展览评估表明,规划的物业是安全的和生产的。

Type 2 diabetes is a long-lived condition that prevents the insulin human system properly using. Insulin sensitivity is a condition that affects patients with type 2 diabetes. This type of diabetes seems to be more common among people in their early and middle years of life. In the proposed hybrid model is the combination of cascaded feed forward neural network (CFFNN) and Lasso Regression method. Lasso regression has always been a kind of regression in deep learning, which participate in training with the decision of functions. The absolute magnitude of the regression coefficient is prohibited. For the simulation of proposed method utilize MATlab (r2018b). For the analysis Diabetes Type2 Patient use Pima Indian and UCI data sets. The proposed hybrid approach shows better outcomes as compare to other recently presented methods in terms of accuracy and other performance parameters.
2型糖尿病是一种长期存在的疾病,它阻碍了人体胰岛素系统的正常使用。胰岛素敏感性是一种影响2型糖尿病患者的疾病。这种类型的糖尿病似乎更常见的人在他们的早期和中年的生活。所提出的混合模型是级联前馈神经网络(CFFNN)和Lasso回归方法的结合。Lasso回归一直是深度学习中的一种回归,它与函数的决策一起参与训练。回归系数的绝对值是禁止的。利用MATlab (r2018b)对所提出的方法进行仿真。对于2型糖尿病患者的分析,使用Pima Indian和UCI数据集。与最近提出的其他方法相比,所提出的混合方法在准确性和其他性能参数方面显示出更好的结果。
