Deafness and voice impairment have been persistent disabilities throughout history, hindering individuals from engaging in verbal communication and leading to their isolation from the predominantly vocally communicating society. Sign language has emerged as the primary mode of communication for people with these disabilities. However, it presents a language barrier as it is not commonly understood by those who can hear. To address this issue, various methods for recognizing sign language have been proposed. This paperaims to develop a machine learning-based system that can recognize sign language in real-time. The paper involved the acquisition of a dataset consisting of 44,654 images representing the static American Sign Language (ASL) alphabet signs. The HandDetector module was utilized to detect and capture images of the signer's hand forming each sign through a PC webcam. The dataset was split into three sets: training data (20,772 cases), validation data (8,903 cases), and test data (14,979 cases). Image pre-processing techniques were implemented on the images and a convolutional neural network (CNN) model was trained and compiled. The CNN utilized in the paper comprised of three convolutional layers and a SoftMax output layer and it was compiled using the Adam optimizer and categorical cross-entropy loss function. The performance of the system was evaluated using the test dataset. Notably, the system achieved remarkable accuracy rates, having a training accuracy of 99.86%, a validation accuracy of 99.94%, and a test accuracy of 94.68%. The results obtained from this study demonstrated significant advancements in sign language recognition, surpassing previous findings in the literature.
耳聋和声音障碍是历史上一直存在的残疾,阻碍了个人进行语言交流,并导致他们与以语言交流为主的社会隔离。手语已经成为这些残疾人的主要交流方式。然而,它呈现出语言障碍,因为那些能听到的人通常听不懂。为了解决这个问题,人们提出了各种识别手语的方法。本文旨在开发一种基于机器学习的实时手语识别系统。该论文涉及到一个由44,654张代表静态美国手语(ASL)字母符号的图像组成的数据集的获取。HandDetector模块用于通过PC网络摄像头检测和捕获签名者的手形成每个手势的图像。数据集分为三组:训练数据(20,772例)、验证数据(8,903例)和测试数据(14,979例)。对图像进行预处理,训练并编译卷积神经网络(CNN)模型。本文使用的CNN由三个卷积层和一个SoftMax输出层组成,使用Adam优化器和分类交叉熵损失函数进行编译。使用测试数据集对系统的性能进行了评估。值得注意的是,该系统取得了显著的准确率,训练准确率为99.86%,验证准确率为99.94%,测试准确率为94.68%。这项研究的结果表明,在手语识别方面取得了重大进展,超过了以往的文献研究结果。

IF 4.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2023-08-03 DOI: 10.1109/icABCD59051.2023.10220532

Ocular cataract is among diseases that result in blindness if not treated in time. It affects people worldwide, primarily in underdeveloped countries. This health problem affects the quality of patients' lives. However, early diagnosis avoids blindness and allows the patient to have appropriate treatment. Developing countries, especially those with low income, have a precarious health system, even in the ophthalmology sector, where equipment is lacking. This research aims to develop a deep learning-based model to detect ocular cataracts based on retinal images. We collect 1000 retinal images from Kaggle, which are then equally divided into two classes: with and without cataracts. We then use several neural architectures to correctly classify these images, including ResNet18, ResNet34, InceptionResNetV2, and InceptionV4. We demonstrate that ResNet18 outperforms the other architectures, reaching 95.5% accuracy score. Our results suggest that deep convolutional neural networks can achieve a significant performance in ocular cataracts classification using retinal images.
如果不及时治疗,白内障是导致失明的疾病之一。它影响全世界的人,主要是在不发达国家。这一健康问题影响到患者的生活质量。然而,早期诊断可以避免失明,并使患者得到适当的治疗。发展中国家,特别是低收入国家,卫生系统不稳定,甚至在缺乏设备的眼科部门也是如此。本研究旨在开发一种基于视网膜图像的深度学习模型来检测白内障。我们从Kaggle收集了1000张视网膜图像,然后将其平均分为两类:有白内障和没有白内障。然后,我们使用几种神经结构来正确分类这些图像,包括ResNet18, ResNet34, InceptionResNetV2和InceptionV4。我们证明ResNet18优于其他架构,达到95.5%的准确率得分。我们的研究结果表明,深度卷积神经网络在利用视网膜图像进行白内障分类方面可以取得显著的效果。

Spatiotemporal Convolutions and Video Vision Transformers for Signer-Independent Sign Language Recognition 基于时空卷积和视频视觉变换的独立手语识别
IF 4.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2023-08-03 DOI: 10.1109/icABCD59051.2023.10220534

Sign language is a vital tool of communication for individuals who are deaf or hard of hearing. Sign language recognition (SLR) technology can assist in bridging the communication gap between deaf and hearing individuals. However, existing SLR systems are typically signer-dependent, requiring training data from the specific signer for accurate recognition. This presents a significant challenge for practical use, as collecting data from every possible signer is not feasible. This research focuses on developing a signer-independent isolated SLR system to address this challenge. The system implements two model variants on the signer-independent datasets: an R(2+ I)D spatiotemporal convolutional block and a Video Vision transformer. These models learn to extract features from raw sign language videos from the LSA64 dataset and classify signs without needing handcrafted features, explicit segmentation or pose estimation. Overall, the R(2+1)D model architecture significantly outperformed the ViViT architecture for signer-independent SLR on the LSA64 dataset. The R(2+1)D model achieved a near-perfect accuracy of 99.53% on the unseen test set, with the ViViT model yielding an accuracy of 72.19 %. Proving that spatiotemporal convolutions are effective at signer-independent SLR.
手语是聋人或重听人交流的重要工具。手语识别(SLR)技术可以帮助弥合聋人与正常人之间的沟通差距。然而,现有的单反系统通常依赖于签名者,需要来自特定签名者的训练数据才能准确识别。这对实际使用提出了重大挑战,因为从每个可能的签名者那里收集数据是不可行的。本研究的重点是开发一个独立于签名者的隔离单反系统来解决这一挑战。该系统在签名无关的数据集上实现了两种模型变体:R(2+ I)D时空卷积块和视频视觉变压器。这些模型学习从LSA64数据集的原始手语视频中提取特征,并在不需要手工制作特征、显式分割或姿势估计的情况下对标志进行分类。总体而言,在LSA64数据集上,R(2+1)D模型体系结构在与签名者无关的SLR方面明显优于ViViT体系结构。R(2+1)D模型在未见的测试集上实现了近乎完美的99.53%的准确率,而ViViT模型的准确率为72.19%。证明了时空卷积在与签名无关的单反中是有效的。

The millimeter-wave (mmWave) frequency band is rapidly becoming utilized in wireless technologies due to its large bandwidth and high data throughput. Wireless technology is increasingly becoming the backbone of the Internet of Things (IoT). This has resulted in increased applications of the radio frequency (RF) spectrum and congestion of the microwave band. This can be solved by utilizing more bandwidth at higher frequency bands. One notable application of IoT pertains to radar sensing, which has experienced increased popularity across various domains such as autonomous vehicles, gesture recognition, drones, and health monitoring. Radar sensors have been employed in these applications to perform tasks including proximity sensing, direction detection, speed measurement, target localization, and capturing physiological indicators such as heartbeat and breathing. Several factors have an impact on the performance of radar sensors, encompassing the maximum range for target detection, measurement precision, capability to differentiate between multiple targets, and ability to operate effectively in environments with high levels of noise. This paper presents the design of a 45 nm complementary metal-oxide-semiconductor (CMOS) low noise amplifier (LNA) for a mmWave Ka-band wireless transceiver for radar sensors. The LNA was designed to operate at 0.6V and 700 μA for low power consumption. The LNA consists of an inductive degenerated common source (CS) and a common gate (CG) diode-connected load. The LNA achieves a power gain of 31.19 dB and a noise figure (NF) of 0.133 dB at 30 GHz consuming 0.42 mW of power.
毫米波(mmWave)频段由于其大带宽和高数据吞吐量而迅速应用于无线技术。无线技术正日益成为物联网(IoT)的支柱。这导致了射频(RF)频谱的应用增加和微波频段的拥塞。这可以通过在更高的频带上利用更多的带宽来解决。物联网的一个值得注意的应用是雷达传感,它在自动驾驶汽车、手势识别、无人机和健康监测等各个领域越来越受欢迎。雷达传感器已在这些应用中用于执行任务,包括接近感测、方向检测、速度测量、目标定位以及捕获心跳和呼吸等生理指标。有几个因素会影响雷达传感器的性能,包括目标探测的最大距离、测量精度、区分多个目标的能力,以及在高噪声环境中有效操作的能力。本文设计了一种45 nm互补金属氧化物半导体(CMOS)低噪声放大器(LNA),用于雷达传感器的毫米波ka波段无线收发器。LNA的工作电压为0.6V,电压为700 μA,功耗低。LNA由一个电感退化共源(CS)和一个共门(CG)二极管连接负载组成。该LNA在30 GHz时的功率增益为31.19 dB,噪声系数(NF)为0.133 dB,功耗为0.42 mW。

A Deep Learning Model for Predicting Under-Five Mortality in Zimbabwe 预测津巴布韦五岁以下儿童死亡率的深度学习模型
IF 4.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2023-08-03 DOI: 10.1109/icABCD59051.2023.10220453

The death of children before they reach five years old (under-five mortality or U5M) is a global scourge that has attracted the attention of many governments, including the World Health Organisation and the United Nations. Children under-five in Sub-Saharan Africa are disproportionately susceptible to death, with a fifteen-fold likelihood of death compared to their counterparts in developed countries. Regardless of the numerous efforts by the Zimbabwean Government to improve child health, such as free access to care, provision of nutritional supplements, immunisation programmes and prevention of mother-to-child transmission, the country still has high under-five mortality rates (U5MRs). Zimbabwe's failure to reduce U5MRs to acceptable levels suggests that the current methods must be complemented. Identifying contextual risk factors and children at risk of death could help paediatricians to make timely and targeted interventions and policymakers to review existing and craft new policies to save children's lives. Therefore, this study applied deep learning to Zimbabwe's 2019 Multiple Indicator Cluster Survey data to predict under-five mortality and identify its associated risk factors. The study used a deep neural network with four hidden layers, k-fold cross-validation and the stochastic gradient descent (SGD) optimiser. All layers used the Rectified Linear Unit activation function except the output layer, which used the sigmoid activation for binary classification. The model produced a 90.04% accuracy, 92.39% precision, 87.30% recall and 95.04% area under the curve. Though the model predicts under-five mortality, it does not prescribe the appropriate interventions to save lives, a gap that future studies could fill.
五岁以下儿童死亡(五岁以下儿童死亡或U5M)是一个全球性的灾难,已引起包括世界卫生组织和联合国在内的许多政府的关注。撒哈拉以南非洲五岁以下儿童特别容易死亡,其死亡可能性是发达国家儿童的15倍。尽管津巴布韦政府为改善儿童健康作出了许多努力,例如免费获得护理、提供营养补充、免疫方案和预防母婴传播,但该国五岁以下儿童死亡率仍然很高。津巴布韦未能将5岁以下儿童死亡率降低到可接受的水平,这表明必须补充当前的方法。确定环境风险因素和面临死亡风险的儿童可以帮助儿科医生及时采取有针对性的干预措施,也可以帮助决策者审查现有政策并制定新的政策,以挽救儿童的生命。因此,本研究将深度学习应用于津巴布韦2019年的多指标聚类调查数据,以预测五岁以下儿童死亡率并确定其相关风险因素。该研究使用了具有四个隐藏层的深度神经网络,k-fold交叉验证和随机梯度下降(SGD)优化器。除了输出层使用sigmoid激活进行二值分类外,所有层都使用了Rectified Linear Unit激活函数。该模型的准确率为90.04%,精密度为92.39%,召回率为87.30%,曲线下面积为95.04%。虽然该模型预测了五岁以下儿童的死亡率,但它并没有规定适当的干预措施来挽救生命,这是未来研究可以填补的空白。

Inconsistencies, unclear processes, and procedures in most democratic countries' election management, particularly vote-counting, cause mistrust and dispute in election results. This study explores the perceptions and expectations of electoral stakeholders on vote counting and validation processes in different African countries. Employing thematic analysis and using the Activity Theory as a lens, the research identifies key themes, such as technical aspects, accuracy, speed, efficiency, transparency, security, challenges, improvements, and the roles of observers and Election Management Bodies (EMBs). The findings highlight various challenges, such as poor network coverage, insufficient staff training, and corruption, informing the formation of a requirement specification for vote counting and validation systems. Despite potential drawbacks and challenges associated with technology solutions, the study proposes a set of ideal requirements specifications for an accurate, efficient, transparent, and secure election vote counting and validation process. The study contributes to ongoing discussions on transparency, accessibility, and the use of electronic voting systems to enhance electoral accuracy and integrity.

A web-based communication interface for home automation enables users to remotely control and monitor their home appliances and devices using a web browser. This technology has the potential to improve energy efficiency and convenience of homes, but also raises security and privacy concerns. This paper focus on the development of a web-based home automation communication interface employing the ThingSpeak platform as the cloud interfacing service, an Arduino board as the microcontroller, and the ESP8266 as the internet module. The subsystem components were tested using hardware testing circuits and a software code written using Arduino IDE to determine the standard operating procedure and results show that they all conform to the operating standards. When the PIR sensor was tested a voltage of 0 V was measured on the digital pin 2 of the Arduino when no motion is detected and a voltage of 3.25 V when motion is detected. The MQ7 sensor gave a reading of 1.73 V on the analog data pin when not exposed to CO (carbon monoxide) and a reading of 3.25 V when exposed to CO.
基于网络的家庭自动化通信接口使用户可以使用网络浏览器远程控制和监控他们的家用电器和设备。这项技术有可能提高能源效率和家庭的便利性,但也引起了安全和隐私方面的担忧。本文以ThingSpeak平台为云接口服务,以Arduino板为微控制器,以ESP8266为互联网模块,重点开发基于web的家庭自动化通信接口。采用硬件测试电路和Arduino IDE编写的软件代码对子系统组件进行了测试,确定了标准的操作程序,结果表明它们都符合操作标准。在测试PIR传感器时,Arduino的数字引脚2在没有检测到运动时测量到0 V电压,在检测到运动时测量到3.25 V电压。当不暴露于CO(一氧化碳)时,MQ7传感器在模拟数据引脚上的读数为1.73 V,暴露于CO时的读数为3.25 V。

Gamification, a concept that describes the use of game design elements in non-game scenarios, inan attempt to induce fun and motivation in non-game scenarios, has found application in a variety of contexts. In education, popular gamification elements that have been introduced to make learning fun includes the use of points, levels, missions, leaderboards, badges, and avatars. New gamification such as the use of social robots is now in vogue. Despite the enormous potential of these gaming concepts, researchers have unearthed some challenges that face the adoption of gamification in educational systems of Higher Education Institutions. In this study's systematic literature review, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework was used to explore the difficulties encountered when using gamification in training and education at colleges and universities and tosuggest potential solutions. Several researches that employed gamification were elicited from databases such as google scholar, Scopus and research gate. The shortcomings encountered during the deployment of gamification in these studies were summarized. The study's findings reveal that he difficulties encountered when adopting gamification in education and training in higher education institutions can be divided into three categories: design concerns, issues with short-term engagement, and problems with user adaptability. Likewise, potential fixes for the issues were mapped out for future designers of educational gamified systems to follow.
游戏化是一个描述在非游戏场景中使用游戏设计元素的概念,它试图在非游戏场景中引入乐趣和动机,并在各种情境中得到应用。在教育领域,为使学习变得有趣而引入的流行游戏化元素包括使用点数、关卡、任务、排行榜、徽章和化身。新的游戏化,如社交机器人的使用,现在很流行。尽管这些游戏概念具有巨大的潜力,但研究人员发现了在高等教育机构的教育系统中采用游戏化所面临的一些挑战。在本研究的系统文献综述中,使用PRISMA(系统评价和荟萃分析的首选报告项目)框架来探索在高校培训和教育中使用游戏化时遇到的困难,并提出潜在的解决方案。一些使用游戏化的研究是从google scholar、Scopus和research gate等数据库中提取出来的。总结了在这些研究中部署游戏化过程中遇到的缺点。研究结果显示,高等教育机构在教育和培训中采用游戏化时遇到的困难可以分为三类:设计问题、短期参与问题和用户适应性问题。同样,我们也为未来的教育游戏化系统设计师列出了潜在的修复方法。
