—Stroke is an important health issue that affects millions of people globally each year. Early and precise stroke diagnosis is crucial for efficient treatment and better patient outcomes. Traditional stroke detection procedures, such as manual visual evaluation of clinical data, can be time-consuming and error-prone. Computer-aided diagnostic (CAD) technologies have emerged as a viable option for early stroke diagnosis in recent years. These systems analyze medical pictures, such as magnetic resonance imaging (MRI), and identify indicators of stroke using modern algorithms and machine learning approaches. The goal of this review paper is to offer a thorough overview of the current state-of-the-art in CAD systems for early stroke detection. We give an examination of the merits and limits of this technology, as well as future research and development directions in this field. Finally, we contend that CAD systems represent a promising solution for improving the efficiency and accuracy of early stroke diagnosis, resulting in better patient outcomes and lower healthcare costs.

Scientific and effective teaching quality evaluation (QE) is helpful to improve teaching mode and improve teaching quality. At present, calligraphy teaching (CT) QE methods are few in number and have poor evaluation effect. Aiming at these problems, deep learning (DL) is introduced to realize intelligent evaluation of CT quality. First, based on relevant research, the CTQE indicator system is constructed. Secondly, rough set and the principal component analysis (PCA) are used to reduce the dimension of the CTQE index system and extract four common factors. Then, the corresponding index data is input into the BP neural network (BPNN) model optimized by the improved sparrow search algorithm for fitting. Finally, combining the above contents, the improved sparrow search algorithm (ISSA) BPNN model is built to realize the intelligent evaluation of CT quality. The experimental results show that the loss value of ISSA-BPN model is 0.21, and the fitting degree of CT data is 0.953. The evaluation Accuracy is 95%, Precision is 0.945, Recall is 0.923, F1 is 0.942, and AUC is 0.967. These values are superior to the most advanced teaching QE model available. The SSA-BPNNCTQE model proposed in the study has excellent performance in CTQE. This is of positive significance to the improvement of teaching quality and students' calligraphy level. Keywords—Deep learning; calligraphy teaching; BPNN; intelligent evaluation; sparrow search algorithm
科学有效的教学质量评价有助于改进教学模式,提高教学质量。目前,书法教学(CT)量化教学方法数量较少,评价效果较差。针对这些问题,引入深度学习技术来实现CT质量的智能评价。首先,在相关研究的基础上,构建了CTQE指标体系。其次,利用粗糙集和主成分分析(PCA)对CTQE指标体系进行降维,提取出4个共同因子;然后,将相应的指标数据输入到经改进麻雀搜索算法优化的BP神经网络(BPNN)模型中进行拟合。最后,结合上述内容,建立了改进的麻雀搜索算法(ISSA) BPNN模型,实现了CT质量的智能评价。实验结果表明,ISSA-BPN模型的损失值为0.21,CT数据的拟合度为0.953。评价准确度为95%,精密度为0.945,召回率为0.923,F1为0.942,AUC为0.967。这些值优于最先进的教学QE模型。本文提出的SSA-BPNNCTQE模型在CTQE中具有优异的性能。这对提高教学质量和学生书法水平具有积极意义。Keywords-Deep学习;书法教学;摘要利用;智能评估;麻雀搜索算法

—As technology advances and cyber threats continue to evolve, cyber security professionals play a critical role in developing and implementing robust security measures, staying ahead of potential risks, and mitigating the impact of cyber incidents. Many studies have examined the impact of cyber security on banks, without focusing on electronic crimes. Despite its importance, to the best of our knowledge, there are no studies on the impact of cyber security on mitigating electronic crimes in the banking sector. Therefore, the purpose of this study is to ascertain how cyber security affects electronic crimes in the Jordanian banking industry. The study sample consisted of 270 senior Jordanian managers and employees who understand the importance of cyber security in the banking sector in 14 Jordanian commercial banks, listed on the Amman stock exchange. The study used SPSS to evaluate how banks can enhance network security infrastructure to prevent unauthorized access and data breaches and also to find out the role of cybersecurity in granting competitive advantage to banks. A relative importance index (RII) was conducted to rank the importance of variables’ statements and test the hypotheses. The results found the most important method through which banks can effectively mitigate the risk of electronic crimes and ensure the security of customers’ financial data is that banks utilize robust encryption technologies to ensure the protection of customer financial data while it is being transmitted and when it is stored (RII=0.740). About 81.5 % of the sample agree, also, banks that have a strong cyber security system provide a secure platform for digital financial services which increases the competitive advantage as they were ranked first for their relative importance at both the category level and overall ranking with (RII=0.754). The study recommended that the banking industry, must consistently educate its customers on information security techniques and how to avoid hacking into their accounts, and develop an alert system that can raise awareness for both banks and bank customers if there is any possible entry or access to the customer's account or organization confidential information.
-随着技术的进步和网络威胁的不断演变,网络安全专业人员在制定和实施强有力的安全措施、防范潜在风险和减轻网络事件影响方面发挥着关键作用。许多研究调查了网络安全对银行的影响,但没有关注电子犯罪。尽管网络安全很重要,但据我们所知,目前还没有关于网络安全对减轻银行业电子犯罪影响的研究。因此,本研究的目的是确定网络安全如何影响约旦银行业的电子犯罪。研究样本包括在安曼证券交易所上市的14家约旦商业银行的270名约旦高级管理人员和员工,他们了解网络安全在银行业的重要性。该研究使用SPSS来评估银行如何加强网络安全基础设施,以防止未经授权的访问和数据泄露,并找出网络安全在赋予银行竞争优势方面的作用。采用相对重要性指数(RII)对变量陈述的重要性进行排序,并对假设进行检验。结果发现,银行有效降低电子犯罪风险并确保客户金融数据安全的最重要方法是银行利用强大的加密技术来确保客户金融数据在传输和存储时得到保护(RII=0.740)。此外,约81.5%的受访者认为,拥有强大网络安全系统的银行为数字金融服务提供了一个安全的平台,这增加了竞争优势,因为它们在类别水平和总体排名上的相对重要性排名第一(RII=0.754)。该研究建议,银行业必须始终如一地教育其客户了解信息安全技术,以及如何避免黑客入侵他们的账户,并开发一个警报系统,以便在任何可能进入或访问客户账户或组织机密信息的情况下提高银行和银行客户的意识。

—This Mangrove forests in the United Arab Emirates (UAE) provide valuable ecosystem services such as coastal erosion protection, water purification and refuge for a wide variety of plants and animals. Therefore, the first step toward understanding the mangrove forests is the monitoring of this important ecological system. This paper proposes an original study to characterize the mangrove forest environment in the UAE by using polarimetric synthetic aperture radar (PolSAR) remote sensing. Free access C-band dual-PolSAR Sentinel 1 data have been exploited. The elements as of the covariance matrix as well as the entropy/alpha decomposition parameters have been studied. Results show that the VH intensity, the coherence between VV and VH polarimetric channels, the entropy and alpha angle provide the most pronounced signatures that discern mangrove forests. Thus, these parameters could be exploited to improve the accuracy of the remote sensing monitoring and mapping techniques of mangrove forests in the UAE.

—Cloud computing involves the dynamic provision of virtualized and scalable resources over the Internet as services. Different types of services with the same functionality but different non-functionality features may be delivered in a cloud environment in response to customer requests, which may need to be combined to satisfy the customer's complex requirements. Recent research has focused on combining unique and loosely-coupled services into a preferred system. An optimized composite service consists of formerly existing single and simple services combined to provide an optimal composite service, thereby improving the quality of service (QoS). In recent years, cloud computing has driven the rapid proliferation of multi-provision cloud service compositions, in which cloud service providers can provide multiple services simultaneously. Service composition fulfils a variety of user needs in a variety of scenarios. The composite request (service request) in a multi-cloud environment requires atomic services (service candidates) located in multiple clouds. Service composition combines atomic services from multiple clouds into a single service. Since cloud services are rapidly growing and their Quality of Service (QoS) is widely varying, finding the necessary services and composing them with quality assurances is an increasingly challenging technical task. This paper presents a method that uses the firefly optimization algorithm (FOA) and fuzzy logic to balance multiple QoS factors and satisfy service composition constraints. Experimental results prove that the proposed method outperforms previous ones in terms of response time, availability, and energy consumption.
云计算包括在互联网上作为服务动态提供虚拟化和可扩展的资源。根据客户的请求,可能会在云环境中交付具有相同功能但非功能特性不同的不同类型的服务,这些服务可能需要组合起来以满足客户的复杂需求。最近的研究集中在将独特的和松散耦合的服务组合到首选系统中。优化后的组合服务由以前存在的单个和简单服务组合而成,以提供最佳的组合服务,从而提高服务质量(QoS)。近年来,云计算推动了多供应云服务组合的快速增长,其中云服务提供商可以同时提供多个服务。服务组合可以满足各种场景下的各种用户需求。多云环境中的组合请求(服务请求)需要位于多个云中的原子服务(服务候选)。服务组合将来自多个云的原子服务组合为单个服务。由于云服务正在快速增长,其服务质量(QoS)变化很大,因此找到必要的服务并将其与质量保证组合在一起是一项越来越具有挑战性的技术任务。提出了一种利用萤火虫优化算法(FOA)和模糊逻辑来平衡多个QoS因素并满足服务组合约束的方法。实验结果表明,该方法在响应时间、可用性和能耗方面都优于现有方法。

Melanoma, a prevalent and formidable skin cancer, necessitates early detection for improved survival rates. The rising incidence of melanoma poses significant challenges to healthcare systems worldwide. While deep neural networks offer the potential for precise melanoma classification, the optimization of hyperparameters remains a major obstacle. This paper introduces a groundbreaking approach that harnesses the Manta Rays Foraging Optimizer (MRFO) to empower melanoma classification. MRFO efficiently fine-tunes hyperparameters for a Convolutional Neural Network (CNN) using the ISIC 2019 dataset, which comprises 776 images (438 melanoma, 338 non-melanoma). The proposed cost-effective DenseNet121 model surpasses other optimization methods in various metrics during training, testing, and validation. It achieves an impressive accuracy of 99.26%, an AUC of 99.56%, an F1 score of 0.9091, a precision of 94.06%, and a recall of 87.96%. Comparative analysis with EfficientB1, EfficientB7, EfficientNetV2B0, NesNetLarge, ResNet50, VGG16, and VGG19 models demonstrates its superiority.

Surveillance video is now able to play a vital role in maintaining security and protection thanks to the advancement of digital video technology. Businesses, both private and public, employ surveillance systems to monitor and track their daily operations. As a result, video generates a significant volume of data that needs to be further processed to satisfy security protocol requirements. Analyzing video requires a lot of effort and time, as well as quick equipment. The concept of a video summary was developed in order to overcome these limitations. To work past these limitations, the concept of video summarization has emerged. In this study, a deep learning-based method for customized video summarization is presented. This research enables users to produce a video summary in accordance with the User Object of Interest (UOoI), such as a car, airplane, person, bicycle, automobile, etc. Several experiments have been conducted on the two datasets, SumMe and self-created, to assess the efficiency of the proposed method. On SumMe and the self-created dataset, the overall accuracy is 98.7% and 97.5%, respectively, with a summarization rate of 93.5% and 67.3%. Furthermore, a comparison study is done to demonstrate that our proposed method is superior to other existing methods in terms of video summarization accuracy and robustness. Additionally, a graphic user interface is created to assist the user with summarizing the video using the UOoI.
由于数字视频技术的进步,监控视频现在能够在维护安全和保护方面发挥至关重要的作用。私营和公共企业都采用监视系统来监视和跟踪其日常运营。因此,视频会产生大量的数据,这些数据需要进一步处理才能满足安全协议的要求。分析视频需要大量的精力和时间,以及快速的设备。视频摘要的概念是为了克服这些限制而发展起来的。为了克服这些限制,视频摘要的概念出现了。在本研究中,提出了一种基于深度学习的自定义视频摘要方法。本研究使用户能够根据用户感兴趣的对象(User Object of Interest, UOoI),如汽车、飞机、人、自行车、汽车等,制作视频摘要。在SumMe和self-created两个数据集上进行了多次实验,以评估所提出方法的效率。在SumMe和自建数据集上,总体准确率分别为98.7%和97.5%,总结率为93.5%和67.3%。对比研究表明,本文提出的方法在视频摘要的准确性和鲁棒性方面都优于现有的方法。此外,还创建了图形用户界面,以帮助用户使用UOoI总结视频。
