The User-PC computing system (UPC) has been devised to provide a very low-cost distributed computing platform to members of a group, using idling resources of their personal computers (PCs). Based on the master-worker model, the master PC accepts jobs from users and assigns them to available worker PCs. Unfortunately, an efficient job assignment method has not been implemented yet. In this paper, we propose a static job scheduling algorithm considering the CPU core utilization, for the UPC system. Given a set of independent jobs, this two-stage heuristic algorithm finds an assigned worker for each job in order to minimize the makespan. To efficiently utilize CPU cores in worker PCs, the first stage groups workers and jobs into several classes according to the number of available cores or threads. It then greedily sets up job-worker assignments in each class independently. The second stage improves the assignments with a local search method by randomly moving job-worker assignments between different classes. For evaluation, we conducted experiments using six worker PCs and up to 27 jobs. Our algorithm could reduce the makespan by up to 60% compared to three baseline scheduling algorithms. However, its performance gradually decreases as the number of jobs significantly increases.
用户- pc计算系统(UPC)的设计目的是利用个人计算机(pc)的空闲资源,为小组成员提供一个非常低成本的分布式计算平台。基于主-worker模型,主PC接受来自用户的作业,并将它们分配给可用的worker PC。不幸的是,一种有效的工作分配方法尚未实现。本文针对UPC系统,提出了一种考虑CPU内核利用率的静态作业调度算法。给定一组独立的作业,这个两阶段启发式算法为每个作业找到一个分配的工人,以最小化完工时间。为了有效地利用工作pc中的CPU内核,第一阶段根据可用内核或线程的数量将工作和作业分成几个类。然后,它贪婪地在每个类中独立地设置job-worker分配。第二阶段通过在不同类之间随机移动job-worker分配,使用局部搜索方法改进分配。为了进行评估,我们使用6台工人pc和多达27个工作岗位进行了实验。与三种基线调度算法相比,我们的算法可以将最大完工时间减少60%。但是,随着工作数量的显著增加,其性能逐渐下降。

Social and political activism is one of the pillars of a country's political culture and democratic health. The latest wave of the World Values Survey with a sample of 67,267 respondents in 46 countries, collects two sets of questions on unconventional political actions face-to-face and digitally. A typology of activism and two scales of face-to-face and digital activism (FUPAS and DUPAS) have been obtained. A democratic gap is found between those who participate and those who do not, and another digital gap between those who participate face-to-face and digitally. Its impact has been evaluated by age, more active and more digital young people, and by country, the most active and digital developed countries. Educating for digital citizenship becomes a priority to overcome the divides and improve democratic health.
社会和政治行动主义是一个国家政治文化和民主健康的支柱之一。最新一轮的《世界价值观调查》(World Values Survey)调查了46个国家的67267名受访者,收集了两组关于非常规政治行动的问题,分别是面对面的和数字化的。已经获得了行动主义的类型和面对面和数字行动主义的两个尺度(FUPAS和DUPAS)。参与和不参与的人之间存在民主差距,面对面参与和数字参与之间存在数字差距。它的影响是按年龄、更活跃、更数字化的年轻人和按国家、最活跃、最数字化的发达国家来评估的。数字公民教育成为克服分歧和改善民主健康的优先事项。

With the advent of the internet among people in recent times, usage of social media and expressing views online has become part of everyone's routine. People are sharing their opinions on social media through text, videos, images, etc. Due to the nature of data shared on social media, it could be used to effectively analyze the emotions of humans, understand and model various events. One such event that happened in recent times is a pandemic due to the Covid-19 virus. Through this paper, we try to compare the emotions and sentiments of people worldwide during four phases of complete and relaxed lockdown through tweets. The four phases of lockdown are defined as Constricted Phase, Semi Constricted Phase, Semi Relaxed Phase, Relaxed Phase. This work will enable the community to provide useful insights and show how people adjusted and how they fought themselves to the pandemic.
随着近年来互联网在人们中间的出现,使用社交媒体和在网上表达观点已经成为每个人日常生活的一部分。人们通过文字、视频、图片等在社交媒体上分享自己的观点。由于社交媒体上共享的数据的性质,它可以用来有效地分析人类的情绪,理解和模拟各种事件。最近发生的一个这样的事件是由Covid-19病毒引起的大流行。通过这篇文章,我们试图通过推特来比较世界各地人们在完全和放松封锁的四个阶段的情绪和情绪。封锁的四个阶段定义为紧缩阶段、半紧缩阶段、半放松阶段和放松阶段。这项工作将使社区能够提供有用的见解,并展示人们如何适应以及如何与大流行作斗争。

A literature review was conducted using journal articles and conference proceedings to examine emerging research practices, and applications of synthetic visual data over the past 5 years. The current research examined articles related to research trends in artificial intelligence training intended to improve computer vision and object detection. Search strings were developed and used to retrieve research articles from the ACM and IEEE databases. The resulting articles were examined for trends, general practices, disciplines where the greatest efforts have been made, advances, and relevant production processes. The research reveals that visual synthetic data encompasses filtering, augmentation, and object domain randomization techniques. Further, all of the research that included an evaluation of synthetic visual data suggest that there are noteworthy performance improvements in accuracy. Additionally, producing realistic synthetic data reduces the current limitations related to labeling, image quality, paucity of relevant data, and privacy issues.

With the development of online education, the mining and analysis of educational data has become especially important. In teaching, detecting students' typical errors is an extremely important factor for higher teaching efficacy. Most of the current researches use clustering or decision tree algorithms for partitioning. However, these algorithms more or less fail to recognize the connection between students and the errors they make, and cannot effectively and intuitively derive their typical errors. This paper proposes a framework that combines community detection and association rules to detect students' typical errors in English teaching. First, the framework adds the error auxiliary nodes and obtains the student's error communities and typical errors. Second, it calculates the errors' frequent itemsets, and mines the association rules between errors. And last, it combines the association rules with the error communities to supplement the potential errors, which effectively summarizes students' typical errors in their learning process.
随着在线教育的发展,对教育数据的挖掘和分析变得尤为重要。在教学中,发现学生的典型错误是提高教学效果的一个极其重要的因素。目前的研究大多采用聚类或决策树算法进行分区。然而,这些算法或多或少不能识别学生和他们所犯错误之间的联系,不能有效、直观地推导出他们的典型错误。本文提出了一个社团检测和关联规则相结合的框架来检测学生在英语教学中的典型错误。首先,该框架增加误差辅助节点,得到学生的误差群体和典型误差;其次,计算错误的频繁项集,挖掘错误之间的关联规则;最后,将关联规则与错误群落相结合,对潜在错误进行补充,有效地总结了学生在学习过程中的典型错误。

In the current era, many sectors have changed, including the education sector. With the support of the development of technology and information, it has resulted in changes in business processes in the world of education. Switch from traditional learning models to electronic learning models. Providing learning with the same learning method mechanism for all individuals will reduce the individual's right to receive learning. So that the electronic learning model has shifted to a personal and open learning system, namely learning with the Massive Open Online Course (MOOC). Based on these conditions, appropriate models and techniques are needed to achieve student-oriented learning. The purpose of this study is to identify and classify general criteria for adaptive learning system models in the MOOC system. The method used in this research is through literature studies on papers published in the last five years (2016–2020). The results showed a general model that is often used as a basis for developing adaptive learning, so that it can be used for further research and development.
在当今时代,许多领域都发生了变化,包括教育领域。在技术和信息发展的支持下,它导致了教育领域业务流程的变化。从传统学习模式转向电子学习模式。为所有个体提供相同的学习方法机制会降低个体接受学习的权利。因此,电子学习模式已经转变为个人和开放的学习系统,即大规模开放在线课程(MOOC)的学习。基于这些条件,需要适当的模式和技术来实现以学生为中心的学习。本研究的目的是识别和分类MOOC系统中自适应学习系统模型的一般标准。本研究采用的方法是通过对近五年(2016-2020)发表的论文进行文献研究。结果显示了一个通用模型,该模型经常被用作开发适应性学习的基础,因此它可以用于进一步的研究和开发。

Computer laboratories, or simply labs, are crucial in many fields including Information Technologies (IT), Management Information Systems (MIS), Computer Science (CS) and Software Engineering (SE). Labs play a vital role in helping students achieve the know-how and develop problem solving, communication and collaboration skills. Traditional labs comprising desktop computers organized into lines or U shapes have been around for almost forty years. Many of the contemporary labs look very different from their ancestors. They are designed to facilitate a myriad of learning activities including solo learning, testing and perhaps foremost, collaborative group work. This paper reviews some ergonomics issues and investigates examples of innovative labs being developed nowadays. We elaborate on the innovative labs' powerfulness in addressing the drawbacks of traditional labs as well in supporting innovative teaching methods, student creativity and interactions, and the education eco-system engagement. Further, we present several ergonomic tips as a lab proposal for Zayed University (ZU) and under the computing education research umbrella.
计算机实验室,或简单的实验室,在许多领域至关重要,包括信息技术(IT),管理信息系统(MIS),计算机科学(CS)和软件工程(SE)。实验室在帮助学生获得专业知识和发展解决问题、沟通和协作技能方面发挥着至关重要的作用。将台式电脑排成直线或U形的传统实验室已经存在了近40年。许多现代实验室看起来与它们的祖先大不相同。它们的设计是为了促进无数的学习活动,包括单独学习,测试,也许最重要的是,合作小组工作。本文综述了一些人机工程学问题,并对目前正在开发的创新实验室进行了实例研究。我们详细阐述了创新实验室在解决传统实验室的缺点以及支持创新教学方法,学生创造力和互动以及教育生态系统参与方面的强大功能。此外,我们提出了几个人体工程学技巧,作为扎耶德大学(ZU)和计算教育研究伞下的实验室建议。

We elaborate on the innovative labs' powerfulness in addressing the drawbacks of traditional labs as well in supporting innovative teaching methods, student creativity and interactions, and the education eco-system engagement. Further, we present several ergonomic tips as a lab proposal for Zayed University (ZU) and under the computing education research umbrella.","PeriodicalId":156688,"journal":{"name":"2021 9th International Conference on Information and Education Technology (ICIET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130119270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global pandemic and subsequent quarantine measures and restrictions have posed an array of challenges to the structure and procedure of higher education workflow, which influenced significantly the scope of individual experiences, projected outcomes and estimated quality of higher education in countries across the world. This study focus is the in-depth assessment of individual digital distance and blended learning experiences by relevant groups of stakeholders in Oriental (Mandarin Chinese, Japanese) and European (French, Italian, Spanish, English,) Languages university level programs in regions of Ukraine through the span of educational activities in the timeframe of COVID-19 quarantine measures of March 2020 to January 2021. The survey and analysis of different ICT tools is used to assess the parameters and challenges of individual quality and efficiency of translation of the real life Foreign Languages Acquisition practices into digital blended format, involving activation of interdisciplinary skills and cross-sectorial activities, assisted by ICT tools. The online survey of 14 universities in regional centers of Ukraine provides for disclosure of individual experiences and quality estimation of e-learning and hybrid learning in the framework of COVID-19 lockdown; assessment of individual experiences and quality of e-learning and hybrid learning in the framework of COVID-19 lockdown as compared to traditional, face-to-face learning formats for foreign languages; individual quality assessment of learning process design, programmed leaning outcomes and projected competences for university programs of Oriental and European languages in the framework of COVID-19 lockdown and quarantine measures.
