Communicating with visitors in tourist areas is one of the best means of conveying tourist information to them and introducing and presenting these areas to end users. Therefore, the use and activation of a new technical and digital service will help to deliver appropriate and reliable information to end users even if they speak different languages. With the current rapid pace of the industrial revolution, there is an increasing need to create a space to deal consistently with tourism in general. Therefore, innovation is gaining importance when it comes to the creation and utilisation of emerging technologies to promote tourism goals. Augmented reality (AR) has revitalised many areas by delivering immersive experiences in the digital world and bringing them to life in the real world. This proposed study sought to enrich the experience of users by displaying various tourist spots in the Makkah region to them with the relevant multimedia information to enable them to build a better connection with the archaeological areas and sites in the city of Makkah, which is the religious capital of the Kingdom of Saudi Arabia (KSA) and is considered as the cradle of Islam. This was where the Islamic civilisation was launched and the call of the prophet, peace and blessings be upon him, began, and there are many areas that are rich in ancient history, where diverse situations and information can be presented in a beautiful and attractive way. This study proposed the use of electronic glasses linked to a smart device application based on the use of AR to review archaeological areas using deep learning (DL) and multimedia information that support visitors through a database that was previously fed by databases dedicated to this matter, as well as by using some websites and online videos for the same purpose. A convolutional neural network (CNN) was used by sensors attached to the glasses to correctly identify artifacts and thus, display information associated with the sites in question. To increase the level of accuracy, feedback was obtained through a questionnaire that carefully evaluated the presented information using relevant evaluation models through a place experience scale (PES) as well as the experience of using the triple interaction of the AR. The results of the study were discussed and evaluated comprehensively for its future development using statistical methods. The results of the study will serve to enhance competitiveness by showing the archaeological monuments in the Makkah region and providing visitors with reliable information about them through multiple media that will automatically identify what is presented to them according to the different languages of the visitors.
在旅游区与游客交流是向他们传递旅游信息以及向最终用户介绍和展示这些旅游区的最佳手段之一。因此,使用和激活新的技术和数字服务将有助于向终端用户提供适当和可靠的信息,即使他们说的是不同的语言。随着当前工业革命的迅猛发展,越来越有必要创造一个空间来持续处理整个旅游业。因此,在创造和利用新兴技术促进实现旅游业目标方面,创新正变得越来越重要。增强现实技术(AR)通过在数字世界中提供身临其境的体验,并将其带入现实世界,使许多领域焕发出新的活力。麦加市是沙特阿拉伯王国(KSA)的宗教之都,被视为伊斯兰教的摇篮,是伊斯兰文明的发源地。这里是伊斯兰文明的发源地,也是先知(愿主赐福之,并使其平安)号召的发源地,有许多地区都蕴含着丰富的古代历史,在这里,各种情况和信息都可以以一种美丽而有吸引力的方式展现出来。本研究建议使用与基于 AR 的智能设备应用程序相连的电子眼镜,利用深度学习(DL)和多媒体信息来回顾考古区域,这些信息可通过以前专门用于此问题的数据库提供给游客,也可通过一些网站和在线视频用于相同目的。眼镜上的传感器使用卷积神经网络(CNN)来正确识别文物,从而显示与相关遗址有关的信息。为了提高准确度,还通过问卷调查获得了反馈意见,该问卷通过场所体验量表(PES)以及 AR 三重交互的使用体验,使用相关评估模型对所显示的信息进行了仔细评估。使用统计方法对研究结果进行了讨论和全面评估,以促进其未来发展。研究结果将通过多种媒体展示麦加地区的考古遗迹,并为游客提供可靠的相关信息,根据游客的不同语言自动识别所展示的内容,从而提高竞争力。

The increasing risk of forest fires demands sophisticated detection systems in order to mitigate the environment effectively. The technology under consideration enhances real-time monitoring and reaction by functioning inside an Internet of Things (IoT) architecture. Even though Artificial Intelligence (AI) algorithms have improved fire detection systems, they are quite expensive and energy-intensive due to their high computing needs. With the use of creative methods for data augmentation and optimization as well as a shared feature extraction module, this research study offers a thorough fire detection model using an improved EfficientNet that tackles these issues. Three technical components are creatively combined in the realm of forest fire detection by this study. The first stage is the use of diagonal swap of random (DSRO) data annotation, which makes use of spatial connections in the data to improve the model’s understanding of complex aspects that are essential for precisely identifying possible fire breakouts. By adding a shared feature extraction module across three functions, the second stage solves difficulties in feature extraction and target identification. This greatly increases the model’s performance in complicated forest scenes while reducing false positives and false negatives. The third and final stage focuses on improving the EfficientNet model’s capacity for accurate forest fire categorization. When taken as a whole, these technical components upon creative combination improve the existing technology in forest fire detection and provide a thorough and practical strategy for reducing environmental hazards. For the purpose of hyperparameter tuning in the EfficientNet for the classification of forest fires, an improved Harris Hawks optimization (HHO) is used. By using the Cauchy mutation approach with adaptive weight, HHO expands the search space, boosts population diversity, and improves overall exploration. By including the sine-cosine algorithm (SCA) into the optimization process, the likelihood of local extremum occurrences is decreased. The proposed strategy is successful compared to other existing models, as shown by the experimental findings that show an improvement of 5% in accuracy compared to the standard existing model,  and an improvement of 2% compared to EfficientNet model in detecting forest fire.
森林火灾的风险与日俱增,需要先进的探测系统来有效缓解环境问题。我们正在考虑的技术通过在物联网(IoT)架构内运行来加强实时监控和反应。尽管人工智能(AI)算法已经改进了火灾探测系统,但由于其计算需求高,因此相当昂贵且能源密集。本研究利用创造性的数据增强和优化方法以及共享的特征提取模块,使用改进的 EfficientNet 提供了一个全面的火灾探测模型,以解决这些问题。本研究在林火检测领域创造性地结合了三个技术组件。第一阶段是使用随机对角交换(DSRO)数据注释,利用数据中的空间联系来提高模型对复杂事物的理解能力,这对精确识别可能的火灾爆发至关重要。通过在三个功能中增加一个共享特征提取模块,第二阶段解决了特征提取和目标识别方面的困难。这大大提高了模型在复杂森林场景中的性能,同时减少了误报和漏报。第三阶段也是最后一个阶段的重点是提高 EfficientNet 模型对森林火灾进行准确分类的能力。从整体上看,这些技术组件经过创造性的组合,改进了现有的森林火灾检测技术,为减少环境危害提供了全面而实用的策略。为了在用于林火分类的高效网络中进行超参数调整,使用了改进的哈里斯-霍克斯优化法(HHO)。通过使用具有自适应权重的考奇突变方法,HHO 扩展了搜索空间,提高了种群多样性,并改进了整体探索。通过在优化过程中加入正弦余弦算法(SCA),降低了局部极值出现的可能性。实验结果表明,与其他现有模型相比,所提出的策略是成功的。实验结果表明,与标准现有模型相比,所提出的策略在检测森林火灾方面的准确率提高了 5%,与 EfficientNet 模型相比提高了 2%。

The global changes caused by the health crisis of the COVID-19 coronavirus pandemic have significantly impacted education all over the world. Schools today have had to adopt distance learning models using digital tools to ensure the continuity of educational systems in different circumstances. For this reason and to ensure the continuity of education even in the event of future disruptions in Morocco (war, pandemic, natural disaster...). The Minister of National Education for Preschool and Sport has unveiled an initiative to establish digital classrooms within the educational institutions of the Kingdom. This innovative pedagogical approach, grounded in the utilization of digital tools, is specifically designed to bolster the instruction of science subjects, (Mathematics, Physics, and Life and Earth Sciences). This digital educational transformation has emerged as a highly suitable mode of learning, catering to a diverse array of social groups, including individuals with disabilities and refugees. The primary objective of this research is to assess the influence of digital classrooms on the performance of science educators operating within the Rabat Sale Kenitra region. The intention is to gauge how this technological implementation has affected their teaching methods and overall effectiveness. Furthermore, this study seeks to gauge the progression of this educational transformation and advocate for the wider adoption of digital pedagogy, extending its incorporation into the instructional strategies of other subjects. The ultimate goal is to promote inclusivity and level the playing field for all learners, ensuring equal educational opportunities for every student.
COVID-19 冠状病毒大流行造成的健康危机所引发的全球变化对全世界的教育产生了重大影响。如今的学校不得不采用利用数字工具的远程学习模式,以确保教育系统在不同情况下的连续性。因此,为了确保教育的连续性,即使在摩洛哥未来发生混乱的情况下(战争、大流行病、自然灾害......)。国家学前教育和体育部长提出了一项在王国教育机构内建立数字教室的倡议。这一创新的教学方法以利用数字工具为基础,专门用于加强理科科目(数学、物理、生命科学和地球科学)的教学。这种数字教育变革已成为一种非常适合的学习模式,可满足包括残疾人和难民在内的各种社会群体的需求。本研究的主要目的是评估数字课堂对拉巴特-萨利-凯尼特拉地区科学教育工作者工作表现的影响。目的是评估这一技术的实施如何影响了他们的教学方法和整体效率。此外,本研究还试图衡量这一教育变革的进展情况,并倡导更广泛地采用数字教学法,将其扩展到其他学科的教学策略中。最终目标是促进包容性,为所有学习者提供公平的竞争环境,确保每个学生享有平等的教育机会。

The lives of people are at risk from security and safety risks with Intelligent Transportation Systems (ITS), particularly Autonomous Vehicles. In contrast to manual vehicles, the Security of an AV’s computer and communications components may be penetrated using sophisticated hacking methods, preventing us from employing AVs in our daily lives. The Internet of Vehicles, which connects manual automobiles to the Internet, is vulnerable to cyber-attacks such as lack of service, spoofing, sniffer, widespread denial of service and repeat attacks. This paper presents a unique intrusion detection system for ITS, using Enhanced Cuttle Fish Optimized Multiscale Convolution Neural Network (ECFO-MCNN), that uses vehicles to identify networks and infrastructure and detects careful network activity of in-vehicle networks. The primary goal of the suggested strategy is to identify forward events emanating through AVs’ central network gateways. Two benchmark datasets, namely the UNSWNB15 dataset for external network communications and the car hacking dataset for in-vehicle communications, are used to assess the proposed IDS. The evaluation’s findings showed that the performance of our suggested system is superior to that of traditional intrusion detection methods.
智能交通系统(ITS),尤其是自动驾驶汽车的安全和安保风险危及人们的生命安全。与手动车辆相比,自动驾驶汽车的计算机和通信组件的安全性可能会被复杂的黑客手段攻破,使我们无法在日常生活中使用自动驾驶汽车。将手动汽车连接到互联网的车联网很容易受到网络攻击,如缺乏服务、欺骗、嗅探、大范围拒绝服务和重复攻击。本文介绍了一种独特的智能交通系统入侵检测系统,该系统采用增强型刀鱼优化多尺度卷积神经网络(ECFO-MCNN),利用车辆识别网络和基础设施,并检测车载网络的谨慎网络活动。建议策略的主要目标是识别通过自动驾驶汽车中央网络网关发出的前向事件。两个基准数据集,即用于外部网络通信的 UNSWNB15 数据集和用于车内通信的汽车黑客数据集,被用来评估所建议的 IDS。评估结果表明,我们建议的系统性能优于传统的入侵检测方法。

With the rise of machine translation systems, it has become essential to evaluate the quality of translations produced by these systems. However, the existing evaluation metrics designed for English and other European languages may not always be suitable or apply to other Indic languages due to their complex morphology and syntax. Machine translation evaluation (MTE) is a process of assessing the quality and accuracy of the machine-translated text. MTE involves comparing the machine-translated output with the reference translation to calculate the level of similarity and correctness. Therefore, this study evaluates different metrics, namely, BLEU, METEOR, and TER to identify the most suitable evaluation metric for Indic languages. The study uses datasets for Indic languages and evaluates the metrics on various translation systems. The study contributes to the field of MT by providing insights into suitable evaluation metrics for Indic languages. This research paper aims to study and compare several lexical automatic machine translation evaluation metrics for Indic languages. For this research analysis, we have selected five language pairs of parallel corpora from the low-resource domain, such as English–Hindi, English-Punjabi, English-Gujarati, English-Marathi, and English-Bengali. All these languages belong to the Indo-Aryan language family and are resource-poor. A comparison of the state of art MT is presented and shows which translator works better on these language pairs. For this research work, the natural language toolkit tokenizers are used to assess the analysis of the experimental results. These results have been performed by taking two different datasets for all these language pairs using fully automatic MT evaluation metrics. The research study explores the effectiveness of these metrics in assessing the quality of machine translations between various Indic languages. Additionally, this dataset and analysis will make it easier to do future research in Indian MT evaluation.
随着机器翻译系统的兴起,对这些系统产生的译文质量进行评估变得至关重要。然而,由于其他印度语言的形态和语法比较复杂,为英语和其他欧洲语言设计的现有评估指标可能并不总是适合或适用于这些语言。机器翻译评估 (MTE) 是对机器翻译文本的质量和准确性进行评估的过程。MTE 包括将机器翻译输出与参考译文进行比较,以计算相似度和正确性。因此,本研究评估了不同的指标,即 BLEU、METEOR 和 TER,以确定最适合印地语的评估指标。本研究使用了印度语的数据集,并对各种翻译系统的指标进行了评估。通过深入了解适合印度语的评价指标,本研究为 MT 领域做出了贡献。本研究论文旨在研究和比较针对印度语的几种词法自动机器翻译评估指标。为了进行研究分析,我们从低资源领域选择了五对语言的平行语料,如英语-印度语、英语-印度孟加拉语、英语-古吉拉特语、英语-马拉地语和英语-孟加拉语。所有这些语言都属于印度-雅利安语系,资源贫乏。本报告对最先进的 MT 进行了比较,并显示了哪种翻译器在这些语言对上效果更好。在这项研究工作中,使用了自然语言工具包标记化器来评估分析实验结果。这些结果是通过使用全自动 MT 评估指标对所有这些语言对的两个不同数据集得出的。这项研究探讨了这些指标在评估各种印度语言之间机器翻译质量方面的有效性。此外,该数据集和分析将使未来的印度语 MT 评估研究更加容易。

As advancements in healthcare technologies continue to emerge, the integration of AI-Technology has brought about significant transformations in various healthcare sectors. While substantial advancements have been made in applying AI to enhance physical health, its implementation in the field of mental health is still in its early stages. This descriptive study aims to address this gap by exploring the perspectives of mental health professionals (MHPs) on the acceptance and utilization of AI technology. Unified Theory of Acceptance and Use of Technology (UTAUT) was utilized to assess MHPs’ attitudes and beliefs towards AI implementation in psychotherapeutic practices. The sample was compromised of 349 MHPs. The findings reveal the task characteristic (TC) domain as the most influential domain, followed by Performance expectancy (PE), Behavioural intentions (BI), Personal innovativeness in IT (PT), Social influence (SI), Effort expectancy (EE), Perceived substitution crisis (PSC), Technology characteristic (TECH), and Initial trust (IT). The study also identifies statistically significant differences in AI usage based on gender variable, with females demonstrating a higher level of AI usage in comparison to males. Furthermore, the study highlights diverse applications of AI in the field of mental health, including AI-assisted assessments (AAA), chatbots for psychotherapy support (CPS), and data analytics for personalized treatment recommendations (DAPTR). By incorporating mental healthcare professionals’ (MHPs) perspectives, this research significantly contributes to a comprehensive understanding of the acceptance and utilization of AI technology in psychotherapy. The findings offer valuable insights into MHPs’ perceptions, concerns, and perceived advantages associated with integrating AI technology within clinical settings in the field of mental health.
随着医疗保健技术的不断进步,人工智能与技术的融合为各个医疗保健领域带来了重大变革。虽然在应用人工智能改善身体健康方面取得了长足进步,但其在心理健康领域的应用仍处于早期阶段。这项描述性研究旨在通过探讨精神卫生专业人员(MHPs)对接受和使用人工智能技术的看法来弥补这一不足。研究采用了 "技术接受与使用统一理论"(UTAUT)来评估精神卫生专业人员对在心理治疗实践中实施人工智能的态度和信念。样本由 349 名 MHPs 组成。研究结果显示,任务特征(TC)领域是最具影响力的领域,其次是绩效预期(PE)、行为意向(BI)、信息技术中的个人创新性(PT)、社会影响(SI)、努力预期(EE)、感知替代危机(PSC)、技术特征(TECH)和初始信任(IT)。研究还发现了基于性别变量的人工智能使用率统计上的显著差异,女性的人工智能使用率高于男性。此外,研究还强调了人工智能在心理健康领域的各种应用,包括人工智能辅助评估(AAA)、用于心理治疗支持的聊天机器人(CPS)以及用于个性化治疗建议的数据分析(DAPTR)。通过纳入心理保健专业人员(MHPs)的观点,本研究极大地促进了对心理治疗中接受和使用人工智能技术的全面理解。研究结果为了解心理保健专业人员对将人工智能技术整合到心理健康领域临床环境中的看法、关注点和感知到的优势提供了宝贵的见解。

Diseases of crop plants pose a serious danger to agricultural output and progress. Predicting the onset of a disease outbreak in advance can help public health officials better manage the pandemic. Precision agriculture (PA) applications rely heavily on current information and communication technologies (ICTs) for their contribution to long-term sustainability. Preventative measures against plant diseases require accurate early disease prediction in order to be effective. The current computer vision-based illness detection technology can only detect the disease after it has already manifested. This research intends to provide a deep learning (DL) method for early disease attack prediction using Internet of Things (IoT) directly sensed environmental factors from crop fields. There is a robust relationship between environmental factors and the life cycles of plant diseases. Disease incidence in plants can be forecast based on environmental variables in the crop field. In order to solve these issues, the research presented here suggests using a gated recurrent multi-attention neural network (GRMA-Net). The study uses multilevel modules to zero down on informative areas in order to extract additional discriminative features, as informative characteristics tend to appear at various levels in a network. In order to capture long-range dependence and contextual interaction, these characteristics are first organised as spatial sequences and then input into a deep-gated recurrent unit (GRU). Finally, an enhanced version of the Tunicate swarm optimisation model (ITSO) is used to pick the best values for the model’s hyper-parameters. Four public datasets representing a wide range of crop types are used to assess the model’s efficacy. Some of these databases cover numerous crop species, like PlantVillage (38 categories), while others focus on a single crop, such as Apple (4), Maize (4), or Rice (5). The experimental findings show that the system achieves 99.16% accuracy in identifying agricultural diseases, which is higher than the accuracy of other current deep-learning approaches.
作物病害对农业产量和进步构成严重威胁。提前预测疾病爆发可以帮助公共卫生官员更好地管理大流行病。精准农业(PA)应用在很大程度上依赖于当前的信息和通信技术(ICTs),以促进其长期可持续性。针对植物病害的预防措施需要准确的早期病害预测才能奏效。目前基于计算机视觉的病害检测技术只能在病害发生后才能检测到病害。本研究旨在提供一种深度学习(DL)方法,利用物联网(IoT)直接感知作物田的环境因素,进行早期病害侵袭预测。环境因素与植物病害的生命周期之间有着密切的关系。根据作物田间的环境变量可以预测植物的病害发生率。为了解决这些问题,本文介绍的研究建议使用门控递归多注意神经网络(GRMA-Net)。由于信息特征往往出现在网络的不同层次,因此该研究使用多层次模块将信息区域归零,以提取额外的判别特征。为了捕捉长程依赖性和上下文相互作用,这些特征首先被组织成空间序列,然后输入深度门控递归单元(GRU)。最后,使用增强版图纳特蜂群优化模型(ITSO)为模型的超参数选取最佳值。为评估该模型的功效,使用了代表多种作物类型的四个公共数据集。其中一些数据库涵盖众多作物种类,如 PlantVillage(38 个类别),而其他数据库则侧重于单一作物,如苹果(4 个)、玉米(4 个)或水稻(5 个)。实验结果表明,该系统识别农业疾病的准确率达到 99.16%,高于目前其他深度学习方法的准确率。

Stock trading is a popular and important profession that requires near-to-perfect data analytical skills, mathematical and statistical knowledge, and a broad understanding of buying and selling stocks. Often, due to the number of factors to consider and the intervention of human bias, traders and investors make wrong decisions that cost them millions of dollars. Therefore, automated algorithmic trading has gained traction in the marketplace due to its ability to process huge amounts of data, perform mathematical calculations and make quick and effective decisions. Most algorithmic trading strategies rely on a single technical indicator; however, it has been found that combining two or more indicators makes a trading strategy profitable. Therefore, this paper proposes a custom algorithmic trading strategy that combines important technical indicators such as the Exponential Moving Average and Relative Strength Index and utilizes sentiment analysis of financial news as well. This combination of technical indicators and sentiment analysis is not prevalent in existing research. The performance of the strategy was tested on fifteen stocks from different sectors of the US market using Python’s VectorBt library. The results showed that most of the stocks produced a higher win rate with the custom strategy as compared to other strategies, with the highest win rate of 88% for the S&P 500 index. To carry out sentiment analysis, a NLP model using BERT was developed which achieved an accuracy of 84%. Finally, to test the strategy on real-time data, paper trading was carried out on the Alpaca API and after six months the portfolio’s ROI is 6.26%.
股票交易是一个热门而重要的职业,需要近乎完美的数据分析技能、数学和统计知识,以及对买卖股票的广泛了解。由于需要考虑的因素众多,加上人为偏见的干预,交易员和投资者往往会做出错误的决定,从而损失数百万美元。因此,自动算法交易因其能够处理海量数据、进行数学计算并做出快速有效的决策而在市场上备受青睐。大多数算法交易策略依赖于单一的技术指标,然而,人们发现,将两个或更多的指标结合在一起会使交易策略有利可图。因此,本文提出了一种自定义算法交易策略,该策略结合了指数移动平均线和相对强弱指数等重要技术指标,同时还利用了金融新闻的情感分析。这种将技术指标和情感分析相结合的方法在现有研究中并不普遍。我们使用 Python 的 VectorBt 库在美国市场不同行业的 15 只股票上测试了该策略的性能。结果显示,与其他策略相比,定制策略在大多数股票上的胜率更高,其中标准普尔 500 指数的胜率最高,达到 88%。为了进行情绪分析,使用 BERT 开发了一个 NLP 模型,准确率达到 84%。最后,为了在实时数据上测试该策略,在 Alpaca API 上进行了纸面交易,六个月后,投资组合的投资回报率为 6.26%。
