3D Reconstructions are being appreciated across various fields as a more informative means of visualisation that offers great insight about the qualitative characteristics of the objects or scene under consideration. Hence more research is being carried out in this area as 3D are proving to be of great help to fields such as medicine, for improving the diagnostic accuracy and surgical precision of the medical procedure. It has also found applications in fields such as intelligent robot navigation by reproduction of the depth map of a scene, object recognition and so on. We present a unique proposition to synthesize volumetric reconstructions from a singular or multiple positions of view, based on RGB images/videos. The project aims at rapidly generating all the different parts of the indoor environment, without having to actually observe them in reality.

The University library is one of the parts and parcels of the universities that can assist students and teachers teaching and learning work by providing necessary services related to in-formation sharing, book search, book borrow, research document access, and reading room facilities, among others. A vast amount of the literature works related to library facilities emphasize providing services via offline mode rather than online mode. Most of the existing works on online-based library services focus on a single or limited number of library facilities and resources. The existing research works on university library facilities do not consider multiple library resources, different types of users, and multiple features at the same time. Thus, the existing university library related works mainly suffer from the shortage of library resources along with higher time and cost wastage. To tackle with the existing challenges, this paper presents a mobile application featuring next-generation library facilities for university students in Bangladesh. Our proposed limitless mobile application provides several features for students like book or research document search, borrow, order and access, payment and checkout, course enrollment, reading room allocation, request or donate a book, history, notifications, track order, complaint, among others. By using our proposed application, one member of the university library can access the resources of other university libraries via the membership/join feature. Our review result indicates that the majority of the student users are satisfied with the usefulness and necessity of the proposed mobile application features.
高校图书馆是高校辅助师生教学工作的重要组成部分,为师生提供信息共享、图书检索、图书借阅、研究文献查阅、阅览室设施等服务。大量与图书馆设施相关的文献作品强调通过线下方式而不是线上方式提供服务。现有的基于在线的图书馆服务的大部分工作都集中在单一或有限数量的图书馆设施和资源上。现有的高校图书馆设施研究工作没有同时考虑到多种图书馆资源、不同类型的用户和多种特征。因此,现有高校图书馆相关工作面临的主要问题是图书馆资源短缺,时间和成本浪费较大。为了应对现有的挑战,本文提出了一个为孟加拉国大学生提供下一代图书馆设施的移动应用程序。我们提出的无限移动应用程序为学生提供了几个功能,如书籍或研究文件搜索,借阅,订购和访问,付款和结账,课程注册,阅览室分配,请求或捐赠书籍,历史,通知,跟踪订单,投诉等。通过使用我们提出的应用程序,大学图书馆的一个成员可以通过会员/加入特性访问其他大学图书馆的资源。我们的审查结果表明,大多数学生用户对拟议的移动应用程序功能的有用性和必要性感到满意。

The hard shading caused by dirt accumulation on the PV surface, shadows caused by near structures, trees, and even unwanted materials at the surface of the panels degrades the performance of the PV panels, significantly reducing the power output and its efficiency. However, the detection of shading of the solar panel is a complex and challenging process since the panel's power conversion varies and is affected by several factors such as solar irradiance, temperature, the position of the sun, location of shading, etc. This project created an Artificial Neural Network (ANN) model that detects the hard shading and its coverage to PV panels. The optimum ANN model developed in this study can detect solar panel hard shading coverage with 99.98 % accuracy. The best ANN network topology is 3-60-1 (input-hidden neurons-output) model which provides an excellent generalization ability. This model utilized the tan Sigmoid transfer function for both input-hidden and hidden-output layer, and for the optimization process, Levenberg Marquardt outperformed other algorithms. The optimum ANN model has the lowest MSE value of 0.000020333 and with highest R-values of 0.99992, 0.99989, 0.9999, and 0.99992 for training, validation, testing, and overall, respectively. Based on the sensitivity analysis result, the open-circuit voltage significantly contributes to the solar panel shading detection.
由于光伏板表面的污垢堆积造成的硬遮阳,以及面板表面附近的建筑物、树木甚至不需要的材料造成的阴影,都会降低光伏板的性能,大大降低了输出功率和效率。然而,太阳能电池板遮阳的检测是一个复杂而具有挑战性的过程,因为太阳能电池板的功率转换是不同的,并且受太阳辐照度、温度、太阳位置、遮阳位置等多种因素的影响。该项目创建了一个人工神经网络(ANN)模型,用于检测硬阴影及其对光伏板的覆盖。本研究开发的最优人工神经网络模型可以以99.98%的准确率检测太阳能电池板的硬遮阳覆盖率。最佳的人工神经网络拓扑是3-60-1(输入-隐藏神经元-输出)模型,该模型具有良好的泛化能力。该模型在输入隐藏层和隐藏输出层都使用了tan Sigmoid传递函数,在优化过程中,Levenberg Marquardt优于其他算法。最优ANN模型在训练、验证、测试和总体上的MSE最低为0.000020333,r值最高为0.99992、0.99989、0.9999和0.99992。灵敏度分析结果表明,开路电压对太阳能板遮阳检测有显著影响。

Human health is severely endangered by the novel coronavirus (COVID-19). It is viewed as the worst global health threat humans have faced since the second world war and the WHO recognized it as a pandemic on March 11, 2020. This pandemic led several nations to adopt statewide lockdowns, while the industrial, construction, and transportation activities in several nations were disrupted, which lead to a significant shift in air pollutants. The lockdown, however, significantly impacted the environment and air quality in distinct cities. There are numerous ground stations deployed by pollution control organizations to monitor and collect the air pollutants data, but it is not feasible to set up a ground station in every city. In places where ground stations are not available for data collection, Google Earth Engine (GEE) satellite captured data can be used for data analysis. This study aimed to analyze the changes in air pollutants during the different lockdowns in India, such as nitrogen dioxide(NO2), sulfur dioxide(SO2), and carbon monoxide(CO) that contribute significantly to air pollution. In India, lockdowns were imposed during different periods of 2020, 2021, and 2022, according to COVID-19 waves. The air pollutants data during different waves have been analyzed and compared with the pre-COVID year (2019) data for the same duration. According to the study results, $N$ O2 and $S$ O2 were drastically reduced, but only a minor reduction in CO. Delhi, Jaipur, Ahmedabad, and Mumbai were among the major cities that saw the largest reduction, which was up to 60%.
新型冠状病毒(COVID-19)严重危害人类健康。它被视为自第二次世界大战以来人类面临的最严重的全球健康威胁,世界卫生组织于2020年3月11日将其认定为大流行。这次大流行导致几个国家采取了全州范围的封锁措施,而几个国家的工业、建筑和交通活动被中断,导致空气污染物发生了重大变化。然而,封锁对一些城市的环境和空气质量产生了重大影响。污染控制组织部署了许多地面站来监测和收集空气污染物数据,但不可能在每个城市都建立一个地面站。在没有地面站收集数据的地方,谷歌地球引擎(GEE)卫星捕获的数据可用于数据分析。本研究旨在分析印度不同封锁期间空气污染物的变化,如二氧化氮(NO2)、二氧化硫(SO2)和一氧化碳(CO),这些污染物对空气污染有重要影响。在印度,根据新冠肺炎疫情,分别在2020年、2021年和2022年的不同时期实施了封锁。分析了不同时间段的空气污染物数据,并将其与covid - 19前一年(2019年)相同时间段的数据进行了比较。根据研究结果,N$ O2和S$ O2大幅减少,但CO的减少幅度很小。德里、斋浦尔、艾哈迈达巴德和孟买是减少幅度最大的主要城市,减少幅度高达60%。

The advent of Machine Learning and development in statistics has made it possible to gain crucial insights from immense data obtained from surveys. It has made it easy to interpret huge numbers and made it possible to make predictions with extreme accuracy in a myriad of fields. Healthcare is one such field in which this technology can be extensively applied to make early and precise predictions of diseases based on the medical information of the patient. Arteriosclerosis of the human heart is a major concern worldwide as it is responsible for the majority of deaths. Early signs of arteriosclerosis of human heart prediction based on the health and lifestyle parameters of a patient can prove lifesaving. This research aims to create and train a machine learning model which can predict whether an individual faces a risk of arteriosclerosis. The highest prediction accuracy obtained was 86.8293% by logistic regression.

Because of the nature and characteristics of conveying significant level road security and enhanced traffic the executives, vehicular networks are turning into a key report subject under the intelligent transportation system (ITS). Weighty correspondence gear is introduced under vehicles, which requires a powerful stock, an on-board handling system, and information stockpiling gadgets. To keep up with and further develop the traffic signal system, an assortment of remote correspondence advances is utilized. The ITS can offer types of assistance to traffic specialists as well as security precautionary measures for drivers and travelers. Multiple ways for discussing security and protection issues for vehicle ad hoc networks (VANETs). In this paper, novel routing protocol called Secure VANET communications using Hybrid Trust (SVC-HT) is proposed to protect the communications from the malicious vehicles in the network. We integrated the hybrid trust approach with the clustering mechanism to improve the VANET performances. The proposed SVC-HT consists of two phases such as attacker detection with Cluster Head (CH) selection and reliable route formation for secure data transmission. The experimental outcomes of SVC-HT protocol are compared with three recent VANET protocols in terms of average throughput, Packet Delivery Ratio (PDR), delay, and overhead. The results of SVC-HT outperformed the existing protocols.
由于具有显著的道路安全保障和增强交通管理能力的性质和特点,车辆网络正成为智能交通系统(ITS)下的一个重点研究课题。沉重的通信设备被引入车辆,这需要一个强大的库存,一个车载处理系统和信息存储设备。为了跟上和进一步发展交通信号系统,采用了各种远程通信技术。智能交通系统可以为交通专家提供各种协助,并为司机和旅客提供安全预防措施。讨论车辆自组织网络(vanet)的安全和保护问题的多种方法。本文提出了一种新的路由协议——基于混合信任的安全VANET通信(SVC-HT),以保护网络中的通信免受恶意车辆的攻击。为了提高VANET的性能,我们将混合信任方法与聚类机制相结合。提出的SVC-HT包括两个阶段,即攻击者检测和簇头(CH)选择和可靠的路由形成,以保证数据的安全传输。将SVC-HT协议的实验结果与最近的三种VANET协议在平均吞吐量、分组传输比(PDR)、延迟和开销方面进行了比较。SVC-HT的结果优于现有的协议。

A software Requirements Specification (SRS) document is an NL (Natural Language) written textual specification that documents the functional and non-functional requirements of the system and various expectations of clients in a software development project. To understand the different requirements of the system, developers make use of this SRS document. In this paper, we apply Naive Bayes classifiers - Multinomial and Gaussian over different SRS documents and classify the software requirement entities (Actors and Use Cases) using Machine Learning based methods. SRS documents of 28 different systems are considered for our purpose and we define labels for the entities Actor and Use Case. Multinomial Naive Bayes is a popular classifier because of its computational efficiency and relatively good predictive performance. Out of the classifiers tried out, the Multinomial Naive Bayes recognizes Actors and Use Cases with an accuracy of 91%. Actors and Use Cases can be extracted with high accuracy from the SRS documents using Multinomial Naive Bayes, which then can be used for plotting the Use Case diagram of the system. Automated UML (Unified Modeling Language) model generation approaches have a very prominent role in an agile development environment where requirements change frequently. In this work, we attempt to automate the Requirement Engineering (RE) phase that can improve and accelerate the entire Software Development Life Cycle (SDLC).
软件需求规范(SRS)文档是一种NL(自然语言)编写的文本规范,它记录了软件开发项目中系统的功能和非功能需求以及客户的各种期望。为了了解系统的不同需求,开发人员使用了这个SRS文档。在本文中,我们在不同的SRS文档上应用朴素贝叶斯分类器-多项和高斯分类器,并使用基于机器学习的方法对软件需求实体(参与者和用例)进行分类。我们考虑了28个不同系统的SRS文档,并为实体Actor和Use Case定义了标签。多项朴素贝叶斯因其计算效率和相对较好的预测性能而成为一种流行的分类器。在测试过的分类器中,多项朴素贝叶斯识别参与者和用例的准确率为91%。使用多项式朴素贝叶斯可以从SRS文档中高精度地提取参与者和用例,然后可以用于绘制系统的用例图。自动化UML(统一建模语言)模型生成方法在需求频繁变化的敏捷开发环境中具有非常突出的作用。在这项工作中,我们尝试自动化需求工程(RE)阶段,它可以改进并加速整个软件开发生命周期(SDLC)。

Vehicle ad-hoc network is an intelligent transport system. We investigate trifles of the ad-hoc networking system and discovered there are a number of inconclusive issues that could lead to the network collapse. In this paper we tried to ameliorate the road management system and solve the traffic jam issue in real time. VANET applications enable vehicles to connect to the internet to obtain real time news, traffic and weather reports. In real-time VANET is a scheme system, where assorted volatile vehicles and connecting devices come in concretion with a wireless medium. Vehicle to vehicle (V2V) communication is a wireless network, which exchange information about the speed and location of contiguous vehicles, shows great assurance to help fudge accidents, diminish traffic congestion and flourish the ambience. Recent studies have showed that routing protocols may redact on vehicle networks developed using dynamic road traffic information for select the most suitable forwarding path or node.
车载自组网是一种智能交通系统。我们调查了自组织网络系统的琐事,发现有许多不确定的问题可能导致网络崩溃。本文试图改进道路管理系统,实时解决交通堵塞问题。VANET应用程序使车辆能够连接到互联网以获取实时新闻、交通和天气报告。在实时情况下,VANET是一个方案系统,其中各种各样的易挥发车辆和连接设备与无线介质结合在一起。车对车(V2V)通信是一种无线网络,可以交换相邻车辆的速度和位置信息,对避免事故、减少交通拥堵和美化环境有很大的保证。最近的研究表明,在使用动态道路交通信息开发的车辆网络上,路由协议可能会被修改,以选择最合适的转发路径或节点。

The task of Text-to-Face synthesis is quite intricate and there hasn't been much research done on it, until recently. This is mainly due to the complex nature of human face and it's features, which vary widely over different situations. That being said, the field of Text-to-Image synthesis has gathered considerable interest quite late. In earlier research, generation is mainly done using reconstruction of visuals which correlate to the given words. Due to the rise of generative models in the field of deep learning, there has been a departure from these traditional computer vision based retrieval methods. One of the most significant factors for this change is the introduction of GANs. The idea of learning and reproducing the image as a whole, helped in producing better images. The introduction of attention based mechanisms, helped in synthesizing more detailed images which manages to show several facial features like eye brows, hair color, nose shape etc. In this survey, we discuss and summarize some of the methods used for the purpose of image & face generation and their development over the years.
文本到人脸合成的任务非常复杂,直到最近才有很多研究。这主要是由于人脸的复杂性及其特征,在不同的情况下差异很大。话虽如此,文本到图像的合成领域在相当晚的时候才引起了相当大的兴趣。在早期的研究中,生成主要是通过重建与给定单词相关的视觉效果来完成的。由于生成模型在深度学习领域的兴起,这些传统的基于计算机视觉的检索方法已经有所不同。造成这种变化的最重要因素之一是gan的引入。学习和复制整个图像的想法有助于产生更好的图像。引入基于注意力的机制,有助于合成更详细的图像,这些图像能够显示出几个面部特征,如眉毛、头发颜色、鼻子形状等。在本调查中,我们讨论和总结了一些用于图像和人脸生成的方法及其多年来的发展。
