Cloud computing is rapidly expanding because it allows users to save the development and implementation time on their work. It also reduces the maintenance and operational costs of the used systems. Furthermore, it enables the elastic use of any resource rather than estimating workload, which may be inaccurate, as database systems can benefit from such a trend. In this paper, we propose an algorithm that allocates the materialized view over cloudbased replica sets to enhance the database system's performance in stock market using a Peerto-Peer architecture. The results show that the proposed model (MVCRS) improves the query processing time and network transfer cost by distributing the materialized views over cloudbased replica sets. Also, it has a significant effect on decision-making and achieving economic returns.
云计算正在迅速扩展,因为它允许用户节省开发和实现工作的时间。它还降低了使用系统的维护和操作成本。此外,它允许弹性地使用任何资源,而不是估计工作负载,这可能是不准确的,因为数据库系统可以从这种趋势中受益。在本文中,我们提出了一种基于点对点架构的算法,该算法将物化视图分配到基于云的副本集上,以提高数据库系统在股票市场中的性能。结果表明,该模型(MVCRS)通过将物化视图分布在基于云的副本集上,提高了查询处理时间和网络传输成本。此外,它对决策和实现经济回报也有显著的影响。

The main objective of any educational institution is to provide its students with the best educational knowledge and experience so, they can be employed to meet the labor market demands. Due to the rapidly changing in the technology industry and the expanding need for information technology (IT) professionals. The mismatch between IT graduates and the needs of the labor market leads to their inability to employ and job misplacement. Therefore, this paper aims to identify the most significant factors affecting IT graduates' employability and their ability to compete in the local, regional, and international labor markets through a detailed literature review and by conducting two surveys, one for IT graduates and the other for IT employers. Then, data were collected and analyzed by Statistical Package for Social Sciences (SPSS) 28.0 to build our proposed framework which will integrate all factors and parties involved to enhance graduates’ employability to match the labor market demands. The proposed model will assist all parties in improving their plans for producing graduates who are skilled, knowledgeable, and meet the labor market demands.
任何教育机构的主要目标都是为学生提供最好的教育知识和经验,以便他们能够就业以满足劳动力市场的需求。由于技术行业的快速变化和对信息技术(IT)专业人员的需求不断扩大。资讯科技毕业生与劳动力市场的需求不匹配,导致他们无法就业和工作错位。因此,本文旨在通过详细的文献综述,并通过对IT毕业生和IT雇主进行两项调查,确定影响IT毕业生就业能力和他们在本地、区域和国际劳动力市场竞争能力的最重要因素。然后,利用社会科学统计软件包(SPSS) 28.0对数据进行收集和分析,构建我们提出的框架,该框架将整合所有相关因素和各方,以提高毕业生的就业能力,以满足劳动力市场的需求。所提出的模式将有助于各方改进其培养有技能、有知识、符合劳动力市场需求的毕业生的计划。

Crow search algorithm with time varying flight length Strategies for feature selection 基于时变飞行长度的乌鸦搜索算法特征选择策略
Pub Date : 2022-12-31 DOI: 10.54623/fue.fcij.7.2.1

Feature Selection (FS) is an efficient technique use to get rid of irrelevant, redundant and noisy attributes in high dimensional datasets while increasing the efficacy of machine learning classification. The CSA is a modest and efficient metaheuristic algorithm which has been used to overcome several FS issues. The flight length (fl) parameter in CSA governs crows' search ability. In CSA, fl is set to a fixed value. As a result, the CSA is plagued by the problem of being hoodwinked in local minimum. This article suggests a remedy to this issue by bringing five new concepts of time dependent fl in CSA for feature selection methods including linearly decreasing flight length, sigmoid decreasing flight length, chaotic decreasing flight length, simulated annealing decreasing flight length, and logarithm decreasing flight length. The proposed approaches' performance is assessed using 13 standard UCI datasets. The simulation result portrays that the suggested feature selection approaches overtake the original CSA, with the chaotic-CSA approach beating the original CSA and the other four proposed approaches for the FS task.
Feature Selection (FS)是一种有效的技术,用于去除高维数据集中不相关、冗余和噪声的属性,同时提高机器学习分类的效率。CSA是一种适度而高效的元启发式算法,已被用于克服几个FS问题。CSA中的飞行长度(fl)参数决定了乌鸦的搜索能力。在CSA中,fl设置为固定值。结果,CSA在局部最小值上被蒙蔽的问题困扰着。本文通过引入CSA中线性减小飞长、s型减小飞长、混沌减小飞长、模拟退火减小飞长和对数减小飞长五个新的时间相关飞长概念来解决这一问题。使用13个标准UCI数据集评估了所提出方法的性能。仿真结果表明,建议的特征选择方法优于原始的CSA方法,其中混沌-CSA方法优于原始的CSA方法,而其他四种建议的方法用于FS任务。

One of the most prosperous domains that Data mining accomplished a great progress is Food Security and safety. Some of Data mining techniques studies applied several machine learning algorithms to enhance and traceability of food supply chain safety procedures and some of them applying machine learning methodologies with several feature selection methods for detecting and predicting the most significant key performance indicators affect food safety. In this research we proposed an adaptive data mining model applying nine machine learning algorithms (Naive Bayes, Bayes Net Key -Nearest Neighbor (KNN), Multilayer Perceptron (MLP), Random Forest (RF), Support Vector Machine (SVM), J48, Hoeffding tree, Logistic Model Tree) with feature selection wrapper methods (forward and backward techniques) for detecting food deterioration’s key performance indicators. Therefore, results before and after applying wrapper feature selection methods have been compared, analyzed, and interpreted. In conclusion the proposed model applied effectively and successfully detected the most significant indicators for meat safety and quality with the aim of helping farmers and suppliers for being sure of delivering safety meat for consumer and diminishing the cost of monitoring meat safety.

The e-learning and assessment systems became a dominant technology nowadays and distribute across the globe. With severe consequences of COVID19-like crises, the key importance of such technology appeared in which courses, quizzes and questionnaires have to be conducted remotely. Moreover, the use of Learning Management Systems (LMSs), such as blackboard, eCollege, and Moodle, has been sanctioned in all respects of education. This paper presents an open-source interactive Quiz Maker and Management System (QMMS) that suits the research, education (under-grad, grad, or post-grad), and industrial organizations to perform distant quizzes, training and questionnaires with an integration facility with other LMS tools such as Moodle. The proposed system supports three basic levels: 1) administration, 2) instructors, and 3) learners at the micro-level teaching. The proposed system is adopted using .Net framework integrated with SQL-Server database engine that compromise between performance, security and stability. The proposed QMMS is described through different phases of Software Development Life Cycle (SDLC) including detailed analysis, design, implementation, testing, verification, and maintenance in order to exploit the importance of the analysis and design of LMS from the software engineering point of view. A comparative analysis, among the proposed system and a recent list of challenging ones, is presented in different aspects that shows the effectiveness, reliability and validity of proposed tool. Moreover, the proposed QMMS shows an enhancement ratio of up to 42.19% in response time perspective as compared to Moodle system in the case of massive concurrent transactions.

Steganography is one of the most important tools in the data security field as there is a huge amount of data transferred each moment over the internet. Hiding secret messages in an image has been widely used because the images are mostly used in social media applications. The proposed algorithm is a simple algorithm for hiding an image in another image. The proposed technique uses QR factorization to conceal the secret image. The technique successfully hid a gray and color image in another one and the performance of the algorithm was measured by PSNR, SSIM and NCC. The PSNR for the cover image was in the range of 41 to 51 dB. DWT was added to increase the security of the method and this enhanced technique increased the cover PSNR to 48 t0 56 dB. The SSIM is 100% and the NCC is 1 for both implementations. Which improves that the imperceptibility of the algorithm is very high. The comparative analysis showed that the performance of the algorithm is better than other state-of-the-art algorithms
隐写术是数据安全领域最重要的工具之一,因为互联网上每时每刻都有大量的数据传输。在图片中隐藏秘密信息已经被广泛使用,因为这些图片主要用于社交媒体应用程序。该算法是一种简单的图像隐藏算法。该方法利用QR分解来隐藏秘密图像。该技术成功地将一幅灰度和彩色图像隐藏在另一幅图像中,并通过PSNR、SSIM和NCC对算法的性能进行了测试。封面图像的PSNR在41 ~ 51 dB之间。增加了DWT以提高方法的安全性,这种增强的技术将覆盖PSNR提高到48到56 dB。这两种实现的SSIM为100%,NCC为1。这提高了算法的隐蔽性。对比分析表明,该算法的性能优于其他先进算法
