Online event detection (OED) has seen a rise in the research community as it can provide quick identification of possible events happening at times in the world. Through these systems, potential events can be indicated well before they are reported by the news media, by grouping similar documents shared over social media by users. Most OED systems use textual similarities for this purpose. Similar documents, that may indicate a potential event, are further strengthened by the replies made by other users, thereby improving the potentiality of the group. However, these documents are at times unusable as independent documents, as they may replace previously appeared noun phrases with pronouns, leading OED systems to fail while grouping these replies to their suitable clusters. In this paper, a pronoun resolution system that tries to replace pronouns with relevant nouns over social media data is proposed. Results show significant improvement in performance using the proposed system.
在线事件检测(OED)在研究界兴起,因为它可以快速识别世界上可能发生的事件。通过这些系统,通过将用户在社交媒体上分享的类似文件分组,可以在新闻媒体报道之前很好地指出潜在事件。大多数OED系统使用文本相似度来达到这个目的。其他用户的答复进一步加强了可能表明可能发生事件的类似文件,从而提高了该组的潜力。然而,这些文档有时无法作为独立文档使用,因为它们可能会用代词替换之前出现的名词短语,导致OED系统在将这些回复分组到合适的集群时失败。本文提出了一种针对社交媒体数据,尝试用相关名词代替代词的代词解析系统。结果表明,使用所提出的系统,性能有了显著提高。

Just after the invention of electricity by Michael Faraday, there has been a revolution in the communication technology, which lead to the invention of radio, television, radar, satellite, and mobile. While these machines transformed our life high quality, safer and simpler, they have been associated with alarming probable health hazards owing to their electromagnetic radiation (EMR) emission. Couple of cases it has been reported by personals regarding various health related issues relating to exposure on electromagnetic field (EMF) and EMR. Although couple of persons showed light symptoms and respond by avoiding the electrical field (EF) and EMR fields as much as possible, some others are so much affected that they have changed their entire lifestyle. In this paper, empirical survey study has been carried out in the laboratories of Daffodil International University (DIU) main and permanent campus. It was found that some of the instrument had higher EMFs. The findings from this survey may be helpful for the students to take precautionary measurement who work for long duration in the various laboratories for their practical classes and for the users of the domestic appliances as well as office equipment and industrial instruments.
就在迈克尔·法拉第发明电之后,通信技术发生了一场革命,导致了无线电、电视、雷达、卫星和移动电话的发明。虽然这些机器使我们的生活变得更高质量、更安全、更简单,但由于它们的电磁辐射(EMR)排放,它们可能对健康造成惊人的危害。个人报告了几个案例,涉及接触电磁场和电磁辐射的各种与健康有关的问题。虽然有几个人表现出轻微的症状,并通过尽可能避免电场(EF)和EMR场来应对,但有些人受到的影响非常严重,以至于他们改变了整个生活方式。本文在水仙花国际大学(Daffodil International University, DIU)主校区和永久校区的实验室进行了实证调查研究。结果发现,其中一些仪器的电磁场较高。本调查结果可为长期在各种实验室实习的学生及使用家用电器、办公设备和工业仪器的学生提供预防措施。

This research describes the simple implementation of asynchronous distributed cellular automata and decentralized swarms of asynchronous distributed cellular automata built on top of inter-planetary file system’s publish-subscribe (IPFS PubSub) experimentation. Various publish-subscribe(PubSub) models are described. As an illustration, two distributed versions and a decentralized swarm version of a 2D elementary cellular automaton are thoroughly detailed to highlight the simplicity of implementation with IPFS and the inner workings of these kinds of cellular automata (CA). Both algorithms were implemented, and experiments were conducted throughout five datacenters of Grid’5000 testbed in France to obtain preliminary performance results in terms of network bandwidth usage. This work is prior to implementing a large-scale decentralized epidemic propagation modeling and prediction system based upon asynchronous distributed cellular automata with application to the current pandemic of SARS-CoV-2 coronavirus disease 2019 (COVID-19).

Agriculture plays a significant role in the development of a nation and provides the main source of food production, income, and employment to nations. It was the most practiced occupation in Nigeria and this formed the backbone of the economy in the early 1960s before the discovery of crude oil, which has led to the derail of sufficient food production, exportation, and the agricultural economy at large. Over time, the dry season has always been challenging with little or no rainfall and there are no irrigation facilities that incorporate different saving practices to adapt to these climate changes on their own. In this paper, a cost-effective internet of things irrigation system that is capable of reducing water wastage, manual labor, monitoring tank water level and that can be controlled remotely is designed. The system integrated Arduino UNO with a soil moisture sensor, HCSR04 ultrasonic sensor, and ESP8266 Wi-Fi module that gives the system capable of being controlled remotely via the internet, thus achieving optimal irrigation using the internet of things (IoT). Some of the challenges facing the existing irrigation system are water wastage, poor performance, and high cost of implementation. The design system helps to control water supply to crops when it is needed, and also monitors soil moisture, temperature, and water tank level. After carrying out the experiments for 15 days, the system saved approximately 49% of the water used in traditional irrigation method. The system is useful in large farming areas to minimize human effort and reduce the cost of hiring personnel.
农业在一个国家的发展中扮演着重要的角色,为国家提供粮食生产、收入和就业的主要来源。这是尼日利亚最常见的职业,在原油发现之前的20世纪60年代初,这是经济的支柱,这导致了充足的粮食生产、出口和整个农业经济的脱轨。随着时间的推移,旱季一直是一个挑战,降雨量很少或根本没有降雨,也没有灌溉设施结合不同的节约措施来适应这些气候变化。本文设计了一种具有成本效益的物联网灌溉系统,该系统能够减少水的浪费,减少人工劳动,监测水箱水位,并可以远程控制。该系统将Arduino UNO与土壤湿度传感器、HCSR04超声波传感器和ESP8266 Wi-Fi模块集成在一起,使系统能够通过互联网远程控制,从而利用物联网(IoT)实现最佳灌溉。现有灌溉系统面临的一些挑战是水资源浪费、性能差和实施成本高。该设计系统有助于在需要时控制作物的供水,并监测土壤湿度、温度和水箱水位。经过15天的试验,该系统节省了传统灌溉方法约49%的水。该系统在大型农业地区非常有用,可以最大限度地减少人力劳动,降低雇用人员的成本。

Women have progressed a lot in terms of social empowerment and economics. They are going for higher education, jobs, and many other similar endeavors, but harassment cases have also been on the rise. So, women’s safety is a big concern nowadays, especially in developing countries. Many previous studies and attempts were made to create a feasible safety solution for women. Out of various features to ensure women’s safety in critical situations, location tracking is a very common and key feature in most previously proposed solutions. This study found mechanisms of sending the location to different types of recipients in various women safety solutions. In addition, the advantages and drawbacks of location sending methods in women's safety solutions were analyzed.

Optical character recognition (OCR) is a recognition system used to recognize the substance of a checked picture. This system gives erroneous results, which necessitates a post-treatment, for the sentence correction. In this paper, we proposed a new method for syntactic and semantic correction of sentences it is based on the frequency of two correct words in the sentence and a recursive technique. This approach starts with the frequency calculation of each two words successive in the corpora, the words that have the greatest frequency build a correction center. We found 98% using our approach when we used the noisy channel. Further, we obtained 96% using the same corpus in the same conditions.

Tracking moving objects has been an issue in recent years of computer vision and image processing and human tracking makes it a more significant challenge. This category has various aspects and wide applications, such as autonomous deriving, human-robot interactions, and human movement analysis. One of the issues that have always made tracking algorithms difficult is their interaction with goal recognition methods, the mutable appearance of variable aims, and simultaneous tracking of multiple goals. In this paper, a method with high efficiency and higher accuracy was compared to the previous methods for tracking just objects using imaging with the fixed camera is introduced. The proposed algorithm operates in four steps in such a way as to identify a fixed background and remove noise from that. This background is used to subtract from movable objects. After that, while the image is being filtered, the shadows and noises of the filmed image are removed, and finally, using the bubble routing method, the mobile object will be separated and tracked. Experimental results indicated that the proposed model for detecting and tracking mobile objects works well and can improve the motion and trajectory estimation of objects in terms of speed and accuracy to a desirable level up to in terms of accuracy compared with previous methods.
运动物体的跟踪是近年来计算机视觉和图像处理领域的一个研究课题,而人类的跟踪使其成为一个更重大的挑战。这一类别具有多方面和广泛的应用,如自主推导、人机交互和人体运动分析。跟踪算法的难点之一是与目标识别方法的交互、可变目标的可变外观以及同时跟踪多个目标。本文介绍了一种利用固定摄像机成像的方法,与以往的方法相比,该方法具有高效率和更高的精度。该算法分四个步骤来识别固定的背景并去除其中的噪声。这个背景用于从可移动的物体中减去。然后,在对图像进行滤波的同时,去除拍摄图像中的阴影和噪声,最后利用气泡路由的方法对移动目标进行分离和跟踪。实验结果表明,所提出的运动目标检测与跟踪模型能够较好地提高运动目标和轨迹估计的速度和精度,达到较好的精度。

A convolutional neural network for skin cancer classification 用于皮肤癌分类的卷积神经网络
Pub Date : 2022-04-01 DOI: 10.11591/ijict.v11i1.pp76-84
Nur Nafi’iyah, A. Yuniarti
Skin diseases can be seen clearly by oneself and others. Although this disease is visible on the skin, sometimes we worry if this skin disease is not mild. Some people experience skin diseases directly and quickly go to a dermatologist to have their complaints and symptoms checked. This skin protects the body, especially from the sun, so it can lead to death if something goes wrong. One example of a skin disease that can be deadly is skin cancer or skin tumors. In this research, we classified skin cancer into Benign and Malignant using the convolution neural network (CNN) algorithm. The purpose of this research is to develop the CNN architecture to help identify skin diseases. We used a dataset of 3,297 skin cancer images which are publicly available on the Kaggle website. We propose two CNN architectures that differ in the number of parameters. The first architecture has 6,427,745 parameters, and the second architecture has 2,797,665. With both architectures, the accuracy of the first model is 93%, and the second model is 74%. The first model with the number of parameters 6,427,745 We save for use in the creation of the website. We created a web-based application with the Django framework for skin disease identification.
皮肤病能被自己和他人清楚地看到。虽然这种疾病在皮肤上是可见的,但有时我们担心这种皮肤病是否不轻微。有些人直接经历皮肤病,并迅速去皮肤科医生检查他们的抱怨和症状。这种皮肤可以保护身体,尤其是免受太阳的伤害,所以如果出现问题,它可能会导致死亡。皮肤癌或皮肤肿瘤可能是致命的皮肤病的一个例子。在本研究中,我们使用卷积神经网络(CNN)算法将皮肤癌分为良性和恶性。本研究的目的是开发CNN架构来帮助识别皮肤疾病。我们使用了Kaggle网站上公开的3297张皮肤癌图片的数据集。我们提出了两种参数数量不同的CNN架构。第一个体系结构有6,427,745个参数,第二个体系结构有2,797,665个参数。在这两种架构下,第一个模型的准确率为93%,第二个模型的准确率为74%。第一个模型的参数个数为6,427,745,我们将其保存以用于创建网站。我们用Django框架创建了一个基于web的皮肤病识别应用程序。

In developing countries such as India, with a large aging population and limited access to medical facilities, remote and timely diagnosis of myocardial infarction (MI) has the potential to save the life of many. An electrocardiogram is the primary clinical tool utilized in the onset or detection of a previous MI incident. Artificial intelligence has made a great impact on every area of research as well as in medical diagnosis. In medical diagnosis, the hypothesis might be doctors' experience which would be used as input to predict a disease that saves the life of mankind. It is been observed that a properly cleaned and pruned dataset provides far better accuracy than an unclean one with missing values. Selection of suitable techniques for data cleaning alongside proper classification algorithms will cause the event of prediction systems that give enhanced accuracy. In this proposal detection of myocardial infarction using new parameters is proposed with increased accuracy and efficiency of the existing model. Additional parameters are used to predict MI with more accuracy. The proposed model is used to predict an early diagnosis of MI with the help of expertise experiences and data gathered from hospitals.
在印度等发展中国家,由于人口老龄化严重,获得医疗设施的机会有限,远程和及时诊断心肌梗死有可能挽救许多人的生命。心电图是诊断或发现既往心肌梗死的主要临床工具。人工智能对各个领域的研究以及医学诊断都产生了巨大的影响。在医学诊断中,假设可能是医生的经验,它将被用作预测一种拯救人类生命的疾病的输入。我们观察到,一个正确清理和修剪的数据集比一个缺失值的不干净的数据集提供更好的准确性。选择合适的数据清理技术以及适当的分类算法将导致预测系统的事件,从而提高准确性。在此建议中,提出了使用新参数检测心肌梗死,提高了现有模型的准确性和效率。附加参数用于更准确地预测心肌梗死。该模型利用专家经验和从医院收集的数据来预测心肌梗死的早期诊断。
