The lockdown imposed in many countries due to the deadly effects of COVID-19 caused a huge backlog in offices. A lot of employees have a shift in their working hours and changes in their schedule which makes the manual attendance system less efficient. Employees are preoccupied with the workload so much that it becomes difficult to maintain social distancing in the office space. During these times, where a safe and healthy work environment should be promoted, a mistake from a single person can do irreparable damage to his/her peers. In order to tackle the above problems, we have implemented an automated attendance system to record attendance via QR Scanner, a violation tracker implemented using Internet of Things and Machine Learning which tracks the total number of social distancing and mask violations, a website and an app to display the results. Our software provides a clean and easy to use user-interface which gives the ability to the user to login, view his work calendar, take a note of important announcements made at his/her workplace, keep a track of user’s attendance, and generate a QR code which is unique just to the user.
由于COVID-19的致命影响,许多国家实施了封锁,导致办公室大量积压。很多员工的工作时间会发生变化,日程安排也会发生变化,这使得人工考勤系统的效率降低。员工们忙于工作,很难在办公空间保持社交距离。在需要促进安全和健康的工作环境的时候,一个人的错误可能会对他/她的同事造成无法弥补的伤害。为了解决上述问题,我们实施了一个通过QR扫描仪记录考勤的自动考勤系统,一个使用物联网和机器学习实现的违规跟踪器,跟踪社交距离和口罩违规总数,一个网站和一个应用程序来显示结果。我们的软件提供了一个干净易用的用户界面,使用户能够登录,查看他的工作日历,记下他/她工作场所的重要公告,跟踪用户的出勤情况,并生成用户独有的QR码。

with the increasing integration of automobiles in our daily lives, the number of four-wheelers on the road has seen a substantial jump in the tally. Furthermore, the number of drivers has also increased. Moreover, people nowadays have a slightly higher chance to opt for a taxi for daily commute. With this statistic, a coinciding fact that the number of Parkinson’s Disease cases have also increased cannot be overlooked. Also, the advancement in the technology of machine learning has enabled us to accurately detect Parkinson’s Disease with unorthodox testing techniques like voice analysis. With these things in mind, we have attempted to use machine learning to predict whether a person has Parkinson’s disease or not using their voice samples whilst designing the model to assign higher weights to features that help accurately classify the voice sample. For Example, pitch being a critical factor to determine if the person is showing an excited emotional state. Once the model reaches the desired generalization ability, it can be integrated into the recruiting process of organizations like uber.
随着汽车日益融入我们的日常生活,道路上的四轮车数量大幅增加。此外,司机的数量也有所增加。此外,现在人们选择出租车上下班的可能性也有所增加。有了这个统计数据,一个巧合的事实是,帕金森氏症病例的数量也在增加,这一点不容忽视。此外,机器学习技术的进步使我们能够通过语音分析等非常规测试技术准确检测帕金森氏症。考虑到这些,我们尝试使用机器学习来预测一个人是否患有帕金森病,同时设计模型,为有助于准确分类语音样本的特征分配更高的权重。例如,音调是决定一个人是否表现出兴奋情绪的关键因素。一旦模型达到预期的泛化能力,就可以整合到uber等组织的招聘过程中。

Electric Vehicles (EV) are gaining popularity from the transportation sector, as it causes less harm to the environment. The battery inside the EV can be refilled using battery charging or battery swapping. As battery swapping method is found to be advantageous over battery charging, Battery Swapping Stations (BSS) is presently the hot topic of research. Forecasting of EV arrivals helps in optimal planning of BSS. Back Propagation Neural Network (BPNN) is frequently used in forecasting. BPNN trained with traditional algorithms such as Levenberg Marquardt (LM) gets stuck at the local optima. This problem can be overcomed using metaheuristic algorithms such as Genetic Algorithm (GA). Thus, in this present work a comparative study on forecasting the EV arrivals at BSS is carried out using LM-BPNN and GA-BPNN. The two models have been simulated using MATLAB/Simulink environment and their performance is analysed using metrics such as Mean Square Error (MSE) and simulation time.
电动汽车(EV)因其对环境的危害较小,在交通运输领域越来越受欢迎。电动汽车内部的电池可以通过电池充电或电池交换来重新充满。由于电池换热比充电更有优势,电池换热站成为当前研究的热点。电动汽车到达量的预测有助于BSS的优化规划。反向传播神经网络(BPNN)是一种常用的预测方法。用Levenberg Marquardt (LM)等传统算法训练的bp神经网络会陷入局部最优状态。这个问题可以使用元启发式算法,如遗传算法(GA)来克服。因此,本文采用LM-BPNN和GA-BPNN进行了EV到达BSS的预测对比研究。在MATLAB/Simulink环境下对两种模型进行了仿真,并利用均方误差(MSE)和仿真时间等指标对其性能进行了分析。

Recognition of human activity plays an important role in computer-human interaction, surveillance, reconnaissance, robotics for humans, and understanding interpersonal behaviour relationships. These activities can be recorded as a sequence of still images but only using vision to solve the HAR poses a major task due to problems like scale variation, wide change, in contrast, lighting, viewpoint and occlusions. Thus to address this our work is concentrated on developing and training two deep learning pipelines one Spatiotemporal based and the other being skeletal based on publicly available human activity classification datasets. Moreover, we merge the two pipelines using late fusion and provide a comparison between the three with the existing state of the art algorithms for various activities in the dataset. Finally, we present the future work for the same problem.
人类活动识别在人机交互、监视、侦察、人类机器人以及理解人际行为关系等方面发挥着重要作用。这些活动可以记录为一系列静止图像,但由于尺度变化、宽变化、对比度、照明、视点和遮挡等问题,仅使用视觉来解决HAR是一项主要任务。因此,为了解决这个问题,我们的工作集中在开发和训练两个深度学习管道,一个是基于时空的,另一个是基于公开可用的人类活动分类数据集的骨骼。此外,我们使用后期融合将两个管道合并,并将这三个管道与数据集中各种活动的现有最先进算法进行比较。最后,对今后的工作进行了展望。

This paper presents Zika Virus Analysis. Zika virus infection during pregnancy causes neurological disorder, Guillain-Barre syndrome, and birth defects in newborns. No cure or vaccine is available. The study of genome replication will bring some insight into the Zika virus. One of the important tasks in the cell is Genome replication. The daughter cells inherit its own copy of the genome, and then the cell divides in the process of genome replication. Ori is the position in the genome where the genome replicates. Finding the position of ori is a complicated task even for biologists. This task can be performed using Genome analysis. This paper presents the Genome analysis of Zika virus using innovative programming techniques instead of using a laboratory. Identifying the position ori will help the biologist in finding the position where the genome replication occurs.

The highly volatile nature of the stock market has made stock price prediction as challenging as weather forecasting. Consequently, as a hint of this dread, people don’t invest in the stock market. In this paper, we have discussed hybrid networks and a stacked LSTM network for stock price prediction. Additionally, it also focuses on portfolio optimization done using six different techniques, which focuses on creating best performing portfolios categorized on the basis of sectors. One hybrid neural network consists of 1D-Convolutional layers and LSTM layers, and the other is a combination of GRU and LSTM layers. The stock prices of SBI, Indian Bank, Bank of India are predicted using stacked LSTM and Hybrid Neural Networks and compared using the sliding window of time steps with variable width. The neural networks predict the following day’s closing price using a variable sliding window. The RMSE, MSE, and MAE are used to evaluate the efficiency of these neural networks. The hybrid network is proving to be more competent in various situations.

The different mutated variants of Corona Virus (SARS-CoV-2), affected a large percentage of the world population so far. On this light, any study on understanding the virus’s immunity to vaccines and medicines has greater relevance. Studies on Angiotensin-converting enzyme 2 (ACE2), the main entry receptor for the SARS-COV-2 S protein is significantly important in understanding SARS-COV-2 infection in host cells. The functional implications of various motifs found in the spike glycoprotein and its conformational changes had been studied previously to better understand the pathogenesis. The computational study, described herein, have focused on the disease transmission mechanisms of the virus especially on the receptor recognition mechanisms during viral infection. This study used different computational techniques to identify significant motif of the SARS-CoV-2 S Glycoprotein. Different corona viral genomes were compared against the reference genome (Wuhan seafood market isolate) and the possible intermediate hosts of the virus has been proposed based on the similarity in the motifs which are critical for viral infections. Previous studies on S protein motifs of proteolytic cleavage site are revisited here using computational techniques to suggest the possible intermediate hosts of infection.
迄今为止,冠状病毒(SARS-CoV-2)的不同突变变体影响了世界上很大一部分人口。从这个角度来看,任何了解病毒对疫苗和药物免疫的研究都具有更大的意义。血管紧张素转换酶2 (Angiotensin-converting enzyme, ACE2)是SARS-COV-2 S蛋白的主要进入受体,研究ACE2对了解宿主细胞中的SARS-COV-2感染具有重要意义。在刺突糖蛋白中发现的各种基序的功能意义及其构象变化已经被研究,以更好地了解其发病机制。本文所描述的计算研究集中于病毒的疾病传播机制,特别是病毒感染期间的受体识别机制。本研究使用不同的计算技术来鉴定sars - cov - 2s糖蛋白的重要基序。将不同的冠状病毒基因组与参考基因组(武汉海鲜市场分离物)进行了比较,并根据病毒感染关键基序的相似性提出了病毒可能的中间宿主。本文利用计算技术重新回顾了先前对蛋白水解裂解位点S蛋白基序的研究,以提示可能的感染中间宿主。

The world of the Internet of Things (IoT) has exploded and expanded rapidly in recent years. IoT is made up of several connected devices and sensors that communicate by exchanging data through the internet. With exponential growth in the number of installed devices and sensors, conservation of energy is a buzzing topic in the field. IoT facilitates the conservation of energy by enabling the management of data collected from various sensors. The paper presents an implementation of Energy-aware Smart University focusing on Smart Lighting, Air-conditioning, and Ventilating system, whose scope can be expanded to any electrical appliances. This paper attempts to make a low-cost, energy-efficient system. The proposed solution uses Message Queuing Telemetry Transport (MQTT) Client protocol, an IEEE 802.3 standard Ethernet connectivity shield for internet publishing, and a set of sensors such as PIR Sensor and 5 Megapixel infrared camera supported by the raspberry pi for obtaining real-time data. The electrical appliances are turned on only when motion sensors detect movement, and the presence of humans is confirmed using image processing on pictures captured by the Pi Camera. As a result, a significant amount of energy is saved by preventing the continuous operation of the appliances.

近年来,物联网(IoT)世界迅猛发展。物联网由几个连接的设备和传感器组成,它们通过互联网交换数据进行通信。随着安装的设备和传感器数量呈指数级增长,能量守恒成为该领域的热门话题。物联网通过管理从各种传感器收集的数据来促进能源节约。本文介绍了以智能照明、空调和通风系统为重点的节能智能大学的实施,其范围可以扩展到任何电器。本文试图制造一种低成本、节能的系统。提出的解决方案使用消息队列遥测传输(MQTT)客户端协议,用于互联网发布的IEEE 802.3标准以太网连接屏蔽,以及树莓派支持的一组传感器,如PIR传感器和500万像素红外摄像机,用于获取实时数据。只有当运动传感器检测到运动,并且通过Pi相机拍摄的图像处理确认有人存在时,才会打开电器。因此,通过防止电器的连续运行,可以节省大量的能源。数据使用MySQL数据库存储,可以使用Android应用程序远程访问,这将使其成为一个易于访问和操作的自动化系统。

The dominant causes of visual impairment worldwide are Cataract, Glaucoma, and retinal diseases among patients. The alarming cases of these diseases call for an urgent intervention by early diagnosis. The proposed system is designed and developed to easily facilitate the detection of cataract, glaucoma and retinal diseases among patients. The Logistic Regression, Random Forest, Gradient Boosting and Support Vector Machine algorithms are used for detection. The proposed system will help people to get the proper treatment of the aforementioned diseases at an early stage thus reducing the percentage of blindness being caused. The proposed system evaluates the effectiveness and safety of cataract surgery in eyes with age-related degeneration along with glaucoma and retinal diseases detection. This paper shows the accuracy of algorithms and SVM classifiers based upon the glaucoma, retina, cataract and normal eye’s fundus images. The idea of classifying the images based on its fundus and extracting features is widely known now-a-days and also it plays a vital role in the final outcome. This paper talks about the multiclass built models of these classifiers and on the basis of the ROC curves plotted it predicts the output of the images. As far as the algorithms are concerned, the efficiency of algorithms helps it stand best out of many and in our case Gradient boosting proves to give best results for the eye with cataract with 90% accuracy. Then the supervised algorithms logistic regression and random forest gives the accuracy of 89% and 86% respectively.
