To encourage sustainable progress, it is suggested that in a world connected by virtual platforms, modern society should merge big data, artificial intelligence, machine learning, information and communication technology (ICT), as well as the “Internet of Things” (IoT). When real-life problems are considered, the above technology processes are essential in solving the issues. Food is an essential need of human beings. Food supply has become crucial, and it is very important to increase the adequate cultivation of plants for large populations due to huge population growth. At the same time, farmers are struggling with a variety of food plant diseases that significantly affect the harvesting and production in agricultural fields. Nevertheless, the agricultural productivity of rural areas is directly involved with the increase in the economic growth of developing countries such as Sri Lanka, India, Myanmar and Indonesia. Early identification of crop disease, using a well-established modern technique, is vital. It necessitates a number of processes observing large-scale agricultural fields as a disease can infect different parts of the plant such as leaf, roots, stem and fruit. Most diseases appear in plant leaves and have the potential to spread them all over the field within a very short time. This paper reviews several state-of-the-art methods that can be used for plant leaf disease recognition with a special reference to deep learning based methods.
为了鼓励可持续发展,建议在虚拟平台连接的世界中,现代社会应该融合大数据,人工智能,机器学习,信息和通信技术(ICT)以及“物联网”(IoT)。当考虑到现实生活中的问题时,上述技术过程对于解决问题至关重要。食物是人类的基本需求。粮食供应变得至关重要,由于人口的巨大增长,为大量人口增加足够的植物种植是非常重要的。与此同时,农民正在与各种严重影响农业收获和生产的粮食植物病害作斗争。然而,农村地区的农业生产力直接关系到斯里兰卡、印度、缅甸和印度尼西亚等发展中国家经济增长的增加。利用成熟的现代技术及早发现作物病害至关重要。由于一种疾病可以感染植物的不同部分,如叶、根、茎和果实,因此需要对大规模农田进行一系列观察。大多数病害出现在植物叶片上,并有可能在很短的时间内传播到整个田地。本文综述了几种可用于植物叶片病害识别的最新方法,并特别提到了基于深度学习的方法。

Automated inspection of surface defects is beneficial for casting product manufacturers in terms of inspection cost and time, which ultimately affect overall business performance. Intelligent systems that are capable of image classification are widely applied in visual inspection as a major component of modern smart manufacturing. Image classification tasks performed by Convolutional Neural Networks (CNNs) have recently shown significant performance over the conventional machine learning techniques. Particularly, AlexNet CNN architecture, which was proposed at the early stages of the development of CNN architectures, shows outstanding performance. In this paper, we investigate the application of AlexN et CNN architecture-based transfer learning for the classification of casting surface defects. We used a dataset containing casting surface defect images of a pump impeller for testing the performance. We examined four experimental schemes where the degree of the knowledge obtained from the pre-trained model is varied in each experiment. Furthermore, using a simple grid search method we explored the best overall setting for two crucial hyperparameters. Our results show that despite the simple architecture, AlexN et with transfer learning can be successfully applied for the recognition of casting surface defects of the pump impeller.
表面缺陷的自动化检测在检测成本和时间方面有利于铸造产品制造商,最终影响整体经营绩效。具有图像分类能力的智能系统作为现代智能制造的重要组成部分,在视觉检测领域得到了广泛的应用。卷积神经网络(cnn)执行的图像分类任务最近显示出比传统机器学习技术显著的性能。特别是在CNN架构发展的早期阶段提出的AlexNet CNN架构,表现出了出色的性能。在本文中,我们研究了基于AlexN et CNN架构的迁移学习在铸件表面缺陷分类中的应用。我们使用了包含泵叶轮铸造表面缺陷图像的数据集来测试性能。我们检查了四个实验方案,其中从预训练模型中获得的知识程度在每个实验中都是不同的。此外,使用简单的网格搜索方法,我们探索了两个关键超参数的最佳总体设置。结果表明,尽管结构简单,但结合迁移学习的AlexN网络可以成功地用于泵叶轮铸件表面缺陷的识别。

The apparel industry is considered as one of the most labor-intensive industries where Production Planning and Control (PPC) is considered as an important function, because of its involvement from scheduling each task in the process to the delivery of customer demand. Line planning is a sub-process within PPC, through which the production orders are allocated to production lines according to their setting and due dates of production completion. The decisions that address line planning functions still heavily rely on the expertise of the production planner. When production planners are required to select production lines for the production of a particular type of product, little emphasis has been placed on ways to apportion certain production orders to the most appropriate production system. In this research, a framework is developed using Analytical Network Process (ANP) which is a Multi-Criteria Decision Making (MCDM) method, enabling the incorporation of all the planning criteria in the selection of a production line. The weighted scores obtained by the best alternative production lines are used in a Linear Programming model to optimize the resource allocation in an apparel firm.
服装行业被认为是最劳动密集型的行业之一,生产计划和控制(PPC)被认为是一个重要的功能,因为它涉及到从调度过程中的每个任务到交付客户需求。生产线计划是PPC中的一个子过程,根据生产线的设置和生产完成的截止日期,将生产订单分配到生产线上。解决生产线计划功能的决策仍然严重依赖于生产计划人员的专业知识。当生产计划人员被要求为生产一种特定类型的产品选择生产线时,很少强调如何将某些生产订单分配给最合适的生产系统。在本研究中,使用分析网络过程(ANP)开发了一个框架,这是一种多标准决策(MCDM)方法,可以将所有规划标准纳入生产线的选择中。利用最佳备选生产线的加权得分,建立线性规划模型,对服装企业的资源配置进行优化。

Detection, and classification of medical images have become a trending field of study during the last few decades. There is a considerable amount of vital challenges to be overcome. Ample work has been carried out to provide proper solutions for those key challenges. This study was carried out to extend one such medical image classification process to classify the stages of Diabetic Retinopathy (DR) images from colour fundus images. The study proposes a novel Convolutional Neural Network (CNN) architecture which is considered to be one of the most trending and efficient forms of classification of DR stages. Initially, the preprocessing techniques were employed to the DR fundus images with Green channel extraction and Contrast Limited Adaptive Histogram Equalization (CLAHE). The data augmentation strategy was utilised to increase training images from the DR images. Finally, Feature extraction and classification were carried out by using the proposed CNN architecture. It consists of a 14 layered CNN model, which continues three main classifications. In this proposed classification, the images were classified into a tree structure based binary classification as No_DR and DR at the beginning, and then the DR images were again classified into two classes, namely Pre_Intermediate and Post_Intermediate. Moreover, those two classes were again separately classified into Mild, Moderate, and Proliferate_DR, Severe, respectively. The Kaggle is one of the benchmark dataset repositories which was used in this study. The proposed model was able to achieve accuracies of 81 %, 96%, 84%, and 97% for the above-mentioned classifications, respectively.
在过去的几十年里,医学图像的检测和分类已经成为一个趋势研究领域。有相当多的重大挑战需要克服。已经进行了大量工作,为这些关键挑战提供适当的解决办法。本研究旨在扩展一种医学图像分类过程,从彩色眼底图像中对糖尿病视网膜病变(DR)图像进行分期分类。该研究提出了一种新颖的卷积神经网络(CNN)架构,被认为是最流行和最有效的DR阶段分类形式之一。首先,采用绿色通道提取和对比度有限自适应直方图均衡化(CLAHE)技术对DR眼底图像进行预处理。利用数据增强策略从DR图像中增加训练图像。最后,利用本文提出的CNN架构进行特征提取和分类。它由一个14层的CNN模型组成,该模型延续了三个主要分类。在本文提出的分类中,首先将图像分为基于树结构的二值分类No_DR和DR,然后将DR图像再次分为Pre_Intermediate和Post_Intermediate两类。此外,这两个类别再次分别被分为轻度,中度和增殖,严重。Kaggle是本研究中使用的基准数据库之一。对于上述分类,所提出的模型分别能够达到81%、96%、84%和97%的准确率。

The world is facing an extreme crisis due to the COVID-19 pandemic. The COVID-19 virus interrupts the world's economy and social factors; thus, many countries fall into poverty. Also, they lack expertise in this field and could not make an effort to perform the necessary polymerase chain reaction (PCR) or other expensive laboratory tests. Therefore, it is important to find an alternative solution to the early prediction of COVID-19 infected persons with a low-cost method. The objective of this study is to detect COVID-19 infected individuals through their breathing sounds. To perform this task, twenty-two (22) acoustic features are extracted. The optimum features in each COVID-19 infected breathing sound is identified among these features through a feature engineering method. This proposed feature engineering method is a hybrid model that includes; statistical feature evaluation, PCA, and k-mean clustering techniques. The final results of this proposed Optimum Acoustic Feature Engineering (OAFE) model show that breathing sound signals' Kurtosis feature is more effective in distinguishing COVID-19 infected individuals from healthy individuals.
当前,世界正面临新冠肺炎大流行带来的极端危机。新冠肺炎疫情干扰世界经济和社会因素;因此,许多国家陷入贫困。此外,他们缺乏这一领域的专业知识,无法努力进行必要的聚合酶链反应(PCR)或其他昂贵的实验室测试。因此,寻找一种低成本方法替代COVID-19感染者早期预测的解决方案非常重要。本研究的目的是通过呼吸声音检测COVID-19感染者。为了完成这项任务,提取了22个声学特征。通过特征工程方法,从这些特征中识别出每个COVID-19感染呼吸声的最佳特征。提出的特征工程方法是一个混合模型,包括;统计特征评估,PCA和k-均值聚类技术。该最优声学特征工程(OAFE)模型的最终结果表明,呼吸声信号的峰度特征可以更有效地区分COVID-19感染者和健康个体。

Billions of people use social networks, and they playa significant role in people's lifestyles in the current world. At the same time, due to globalization and other factors, the use of these social platforms is expanding daily, and a variety of activities take place inside these platforms. These networks are centralized, allowing social network-owned companies to track and observe the activities of their users. Therefore, this has been challenged to the privacy of the data of users. Also, these companies tend to sell them to third parties keeping huge profits without users' permission. Since data is the most valuable asset in today's and tomorrow's world, many have pointed out this issue. Even though decentralized, community-driven applications have come to playas a solution to this problem, there is still no successful application that competes with centralized social network platforms. Therefore, this study attempted to develop a decentralized social network architecture with the basic functionalities of a social media platform to assure the privacy of the users' data.
数十亿人使用社交网络,它们在当今世界人们的生活方式中扮演着重要的角色。同时,由于全球化等因素,这些社交平台的使用日益扩大,各种各样的活动在这些平台内发生。这些网络是集中的,允许社交网络所有的公司跟踪和观察用户的活动。因此,这对用户数据的隐私性提出了挑战。此外,这些公司往往在未经用户允许的情况下将其出售给第三方,以获取巨额利润。由于数据是当今和未来世界中最有价值的资产,许多人都指出了这个问题。尽管去中心化的、社区驱动的应用程序已经成为解决这个问题的一种方法,但仍然没有一个成功的应用程序可以与中心化的社交网络平台竞争。因此,本研究试图开发一种具有社交媒体平台基本功能的分散社交网络架构,以确保用户数据的隐私性。

Coronavirus disease was first discovered in December 2019. As of July 2021, within nineteen months since this infectious disease started, more than one hundred and eighty million cases have been reported. The incubation period of the virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can be defined as the period between exposure to the virus and symptom onset. Most of the affected cases are asymptomatic during this period, but they can transmit the virus to others. The incubation period is an important factor in deciding quarantine or isolation periods. According to current studies, the incubation period of SARS-CoV-2 ranges from2 to 14 days. Since there is a range, it is difficult to identify a specific incubation period for suspected cases. Therefore, all suspected cases should undergo an isolation period of 14 days, and it may lead to unnecessarily allocation of resources. The main objective of this research is to develop a classification model to classify the incubation period using machine learning techniques after identifying the factors affecting the incubation period. Patient records within the age group 5–80 years were used in this study. The dataset consists of 500 patient records from various countries such as China, Japan, South Korea and the USA. This study identified that the patients' age, immunocompetent state, gender, direct/indirect contact with the affected patients and the residing location affect the incubation period. Several supervised learning classification algorithms were compared in this study to find the best performing algorithm to classify the incubation classes. The weighted average of each incubation class was used to evaluate the overall model performance. The random forest algorithm outperformed other algorithms achieving 0.78 precision, 0.84 recall, and 0.80 F1-score in classifying the incubation classes. To fine-tune the model AdaBoost algorithm was used.
冠状病毒病于2019年12月首次发现。截至2021年7月,在这种传染病开始以来的19个月内,已报告了超过1.8亿例病例。严重急性呼吸综合征冠状病毒2型(SARS-CoV-2)病毒的潜伏期可以定义为接触病毒和出现症状之间的一段时间。大多数受影响的病例在此期间无症状,但他们可以将病毒传播给他人。潜伏期是决定检疫或隔离期的一个重要因素。根据目前的研究,SARS-CoV-2的潜伏期为2至14天。由于存在一个范围,因此难以确定疑似病例的具体潜伏期。因此,所有疑似病例都应经历14天的隔离期,这可能导致不必要的资源分配。本研究的主要目的是在确定影响潜伏期的因素后,利用机器学习技术开发一个分类模型,对潜伏期进行分类。本研究使用了5-80岁年龄组的患者记录。该数据集由来自中国、日本、韩国和美国等不同国家的500例患者记录组成。本研究发现,患者的年龄、免疫功能状态、性别、与患者的直接/间接接触以及居住地点对潜伏期有影响。本研究比较了几种监督学习分类算法,以寻找表现最佳的孵化类分类算法。每个孵化班的加权平均值用于评估模型的整体性能。随机森林算法在分类孵化类方面优于其他算法,准确率为0.78,召回率为0.84,f1得分为0.80。采用AdaBoost算法对模型进行微调。

As of July 2021, within nineteen months since this infectious disease started, more than one hundred and eighty million cases have been reported. The incubation period of the virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can be defined as the period between exposure to the virus and symptom onset. Most of the affected cases are asymptomatic during this period, but they can transmit the virus to others. The incubation period is an important factor in deciding quarantine or isolation periods. According to current studies, the incubation period of SARS-CoV-2 ranges from2 to 14 days. Since there is a range, it is difficult to identify a specific incubation period for suspected cases. Therefore, all suspected cases should undergo an isolation period of 14 days, and it may lead to unnecessarily allocation of resources. The main objective of this research is to develop a classification model to classify the incubation period using machine learning techniques after identifying the factors affecting the incubation period. Patient records within the age group 5–80 years were used in this study. The dataset consists of 500 patient records from various countries such as China, Japan, South Korea and the USA. This study identified that the patients' age, immunocompetent state, gender, direct/indirect contact with the affected patients and the residing location affect the incubation period. Several supervised learning classification algorithms were compared in this study to find the best performing algorithm to classify the incubation classes. The weighted average of each incubation class was used to evaluate the overall model performance. The random forest algorithm outperformed other algorithms achieving 0.78 precision, 0.84 recall, and 0.80 F1-score in classifying the incubation classes. To fine-tune the model AdaBoost algorithm was used.","PeriodicalId":319650,"journal":{"name":"2021 International Research Conference on Smart Computing and Systems Engineering (SCSE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115369442","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}

With the continuous progress in technology during the past few decades, cloud computing has become a fast-growing technology in the world, making computerized systems widespread. The emergence of Cloud Computing has evolved towards microservice concepts, which are highly demanded by corporates for enterprise application level. Most enterprise applications have moved away from traditional unified models of software programs like monolithic architecture and traditional SOA architecture to microservice architecture to ensure better scalability, lesser investment in hardware, and high performance. The monolithic architecture is designed in a manner that all the components and the modules are packed together and deployed on a single binary. However, in the microservice architecture, components are developed as small services so that horizontally and vertically scaling is made easier in comparison to monolith or SOA architecture. SOA and monolithic architecture are at a disadvantage compared to Microservice architecture, as they require colossal hardware specifications to scale the software. In general terms, the system performance of these architectures can be measured considering different aspects such as system capacity, throughput, and latency. This research focuses on how scalability and performance software quality attributes behave when converting the SOA system to microservice architecture. Experimental results have shown that microservice architecture can bring more scalability with a minimum cost generation. Nevertheless, specific gaps in performance are identified in the perspective of the final user experiences due to the interservice communication in the microservice architecture in a distributed environment.
在过去的几十年里,随着技术的不断进步,云计算已经成为世界上一项快速发展的技术,使计算机化系统广泛存在。云计算的出现已经对microservice概念,高要求的企业对企业应用程序的水平。大多数企业应用程序已经从传统的软件程序统一模型(如单片体系结构和传统SOA体系结构)转向微服务体系结构,以确保更好的可伸缩性、更少的硬件投资和高性能。单片架构的设计方式是将所有组件和模块打包在一起,并部署在单个二进制文件上。然而,在微服务体系结构中,组件被开发为小型服务,因此与单体或SOA体系结构相比,横向和纵向扩展更容易。与微服务体系结构相比,SOA和单片体系结构处于劣势,因为它们需要庞大的硬件规范来扩展软件。一般来说,可以从系统容量、吞吐量和延迟等不同方面衡量这些体系结构的系统性能。本研究的重点是在将SOA系统转换为微服务架构时,可伸缩性和性能软件质量属性的表现。实验结果表明,微服务架构能够以最小的成本带来更大的可扩展性。然而,由于分布式环境中微服务架构中的服务间通信,从最终用户体验的角度确定了性能上的具体差距。

Over half of all electrical fires in installations are caused by arcing due to poorly connected equipment or wiring system failures. Therefore, it is essential to detect arcs and interrupt them using a suitable protective device. This paper provides a modelling simulation and experimental approach to obtain arc voltage and current. The parameters for the theoretical model were turned based on the experimental results. A realistic case study was done to obtain the arc current under parallel and series arcs. As seen from the results, a parallel arc creates a current much higher than the load current, whereas a series arc current is often lower than the load current. Even though a parallel arc current may be detected by an overcurrent device, as it is often intermittent, it may not sustain to be captured by existing protection devices. Therefore, both parallel and series arc detection and interruption demand a reliable protection device.
超过一半的电气火灾是由设备连接不良或布线系统故障引起的电弧引起的。因此,检测电弧并使用合适的保护装置中断电弧是至关重要的。本文提供了一种模型仿真和实验方法来获得电弧电压和电流。根据实验结果对理论模型参数进行了反演。通过实际算例计算了并联和串联电弧下的电弧电流。从结果可以看出,并联电弧产生的电流远高于负载电流,而串联电弧产生的电流通常低于负载电流。即使平行电弧电流可以被过流装置检测到,因为它通常是间歇性的,它可能无法被现有的保护装置捕获。因此,无论是并联还是串联的电弧检测和中断都需要可靠的保护装置。
