Developing viable and robust software is an inescapable artifact of graduate research. The challenges lie in the complexities of developing, deploying, and securing software to support the research objectives. Combined with the transitive nature of students, the management of the software development and launch process is an arduous task. A standardized framework for developing and launching complex software is required. Within a university, individual departments do not typically possess the expertise, resources, software and infrastructure to translate research results to a viable product or tool. Extending upon the research of Hilton et al., [5] we designed a software development pipeline in an integrated multi-disciplinary research context. The integrated and collaborative software pipeline formulated from the onset of the project streamlines the development phase and provides an iterative feedback and testing environment. This approach is applied to the development of automated insulin delivery systems, with the synergistic efforts of interdisciplinary teams yielding a mobile application and server software solutions, and a framework for the iterative advancement of the software capabilities into the future.
开发可行且健壮的软件是研究生研究不可避免的产物。挑战在于开发、部署和保护软件以支持研究目标的复杂性。结合学生的传递性,软件开发和启动过程的管理是一项艰巨的任务。开发和启动复杂软件需要一个标准化的框架。在一所大学中,单个院系通常不具备将研究成果转化为可行产品或工具的专业知识、资源、软件和基础设施。在Hilton等人的研究基础上,我们在集成的多学科研究环境中设计了一个软件开发管道。从项目开始制定的集成和协作的软件管道简化了开发阶段,并提供了迭代反馈和测试环境。这种方法被应用于自动化胰岛素输送系统的开发,跨学科团队的协同努力产生了移动应用程序和服务器软件解决方案,并为软件功能的迭代进步提供了框架。

The use of mobile devices for Internet usage has been rapidly increasing and thus the demand for wireless networks. There have been plenty of scenarios and cases that mobile consumers and businesses get into areas that do not have a reliable wireless coverage because of terrain, buildings and distance. Most of us had been a situation where we need Internet access desperately and the cellular network coverage is non-existent. For businesses using machine-to-machine communication, deploying an infrastructure network can be costly or be faced with too many regulatory issues. This can slow down deployment of machine-to-machine devices or stop it all together. When it comes to machine-to-machine communication or IoT devices, CatM was created as an LTE standard to address the needs of low data throughput at a cheap price point. The current implemented version of CatM is inefficient considering bandwidth utilization, and cellular carriers are already hard pressed for spectrum. Once a CatM device is activated, even when it is not transmitting, 17% of the available spectrum is reserved. Due to this spectrum reservation, this reduces overall speed for other users and reduces the number of users that can actively use the network. Then the issues everyone experiences, lack of coverage and a clean signal, due to terrain, buildings, regulations, costs and running backhaul, deploying cell sites everywhere is challenging. This is the reason why cellular coverage has dead spots or weak signal strength. With cellular spectrum costing billions of dollars, there is a more cost-effective way to utilize existing bandwidth. To improve upon already established ad-hoc networks, this paper will explores using nodes with an LTE connection and then sharing that LTE connection using BATMAN-Adv to nodes outside the coverage area of the cell site. An application for this could be smart meters located in the basements of houses. A meter might be outside the coverage of a local cell site but could communicate to another meter that is wirelessly visible. This would artificially expand the coverage of the cell site without having to invest in deploying more cell sites for a handful of nodes. The next step the paper will explore is redundancy. This is a critical issue, since missed data can be costly and frustrating. By allowing multiple nodes to share their cellular connection, this creates redundancy for when a node unexpectedly drops or if the local cell site has an outage. BATMAN-Adv is just one of many ad-hoc routing protocols available to be deployed. It was chosen because of its ability to run on Linux kernels out of the box without any modifications required. With the testing that was performed it is evident that BATMAN-Adv can support acceptable latency with solid throughput numbers. Further testing showed that in the event of a node or gateway failure, the protocol can reroute the traffic over another path. Layer 3 connections will drop and must be re-established, this is
移动设备对互联网的使用一直在迅速增加,因此对无线网络的需求也在迅速增加。由于地形、建筑和距离的原因,移动消费者和企业进入没有可靠无线覆盖的地区的情况很多。我们大多数人都有这样的情况:我们迫切需要互联网接入,而蜂窝网络覆盖却不存在。对于使用机器对机器通信的企业来说,部署基础设施网络可能成本高昂,或者面临太多的监管问题。这可能会减慢机器对机器设备的部署速度,或者完全停止部署。当涉及到机器对机器通信或物联网设备时,CatM是作为LTE标准创建的,以廉价的价格满足低数据吞吐量的需求。考虑到带宽利用率,目前实现的CatM版本效率低下,而且蜂窝运营商已经面临频谱压力。一旦CatM设备被激活,即使它不发射,也会保留17%的可用频谱。由于这种频谱预留,这降低了其他用户的总体速度,并减少了可以积极使用网络的用户数量。由于地形、建筑、法规、成本和回程等因素,每个人都会遇到的问题是,缺乏覆盖和清晰的信号,在任何地方部署蜂窝基站都是具有挑战性的。这就是蜂窝信号覆盖出现盲点或信号强度较弱的原因。由于蜂窝频谱耗资数十亿美元,有一种更经济有效的方法来利用现有的带宽。为了改进已经建立的自组织网络,本文将探索使用具有LTE连接的节点,然后使用BATMAN-Adv将LTE连接共享到蜂窝站点覆盖区域外的节点。这种技术的应用可能是安装在房屋地下室的智能电表。一个仪表可能在本地小区站点的覆盖范围之外,但可以与另一个无线可见的仪表通信。这将人为地扩大小区站点的覆盖范围,而不必为少数节点投资部署更多的小区站点。本文将探讨的下一步是冗余。这是一个关键问题,因为丢失的数据可能代价高昂且令人沮丧。通过允许多个节点共享它们的蜂窝连接,这可以在节点意外丢失或本地蜂窝站点中断时创建冗余。BATMAN-Adv只是众多可部署的自组织路由协议之一。之所以选择它,是因为它能够在不需要任何修改的情况下在Linux内核上开箱运行。通过执行的测试,很明显BATMAN-Adv可以支持可接受的延迟和可靠的吞吐量数字。进一步的测试表明,在节点或网关发生故障的情况下,该协议可以在另一条路径上重新路由流量。第3层连接将会断开,必须重新建立,这是预料之中的,因为没有运行该网络的基础设施。最后,将该协议与蜂窝调制解调器配对,使该网络具有可移植性。由于只有一个节点需要蜂窝上行链路和两个冗余链路,这意味着该网络可以部署在传统网络无法部署的地方,而且成本较低,因为不需要昂贵的路由硬件。然后,通过优化硬件,这些设备可以在电池或太阳能上运行,这进一步增强了网络的可移植性。ad-hoc网络有其局限性,并且应该预料到它永远不会像传统基础设施网络那样快速或可靠。考虑到这一点,如果在ad-hoc网络上运行正确类型的流量,则可以利用节省的成本和快速部署。对于机器对机器网络,当蜂窝覆盖有限时,使用自组织路由协议可以允许网络扩展,在许多情况下,不可能增加额外的蜂窝覆盖,或者根本不可能。

The world was hit by the Covid-19 pandemic in the beginning of 2020, which forced many educational institutions to shift their classroom-based or face-to-face courses to remote or online mode. Students, instructors and institutions had little time to prepare for this sudden, unanticipated shift. Students who prefer learning face-to-face with instructor in a classroom are more likely to face challenges in learning remotely. To understand the experiences of such students, the author conducted a pilot survey of students whose face-to-face courses were moved to remote learning. This paper reports on the results of the analysis of participant responses. Participants experienced a mix of benefits and challenges due to the unanticipated move to remote learning. Based on the findings, this paper makes some suggestions on the design of remote learning.
2020年初,全球遭受新冠肺炎大流行的打击,许多教育机构被迫将课堂教学或面对面教学转变为远程或在线教学模式。学生、教师和机构几乎没有时间为这种突如其来的、意想不到的转变做好准备。喜欢在课堂上与老师面对面学习的学生更有可能在远程学习中面临挑战。为了了解这些学生的体验,笔者对面对面课程转为远程学习的学生进行了试点调查。本文报告了参与者反应分析的结果。由于意外地转向远程学习,参与者经历了各种好处和挑战。在此基础上,本文对远程学习的设计提出了一些建议。

The important role that technology will play in the future requires that IT literacy, IT fluency, and interest in IT careers, in particular, increase significantly in the near future. This study investigates relationships between a variety of student attributes (e.g., general educational interests, classroom behavior, and gender) and engagement with a set of introductory CS-based educational activities. The goal of the study is to gain a better understanding of how to design CS-based educational content that appeals to broader student populations. Among other findings, the study revealed (unsurprisingly) that interest in math played a significant role in the level of engagement for males having STEM-related interests, while interest in reading played a significant role in the level of engagement for females having non-STEM related interests. The most significant finding of the study was that females having non-STEM related interests engaged more extensively than all other student populations.
技术在未来将扮演的重要角色要求在不久的将来,IT素养、IT流畅性和对IT职业的兴趣,特别是,显著增加。本研究调查了学生的各种属性(如一般教育兴趣、课堂行为和性别)与参与一系列介绍性的基于cs的教育活动之间的关系。这项研究的目的是为了更好地理解如何设计基于计算机科学的教育内容,以吸引更广泛的学生群体。在其他发现中,研究显示(毫不奇怪),对数学的兴趣在具有stem相关兴趣的男性的参与水平中起着重要作用,而对阅读的兴趣在具有非stem相关兴趣的女性的参与水平中起着重要作用。该研究最重要的发现是,拥有非stem相关兴趣的女性比其他所有学生群体更广泛地参与其中。

Assistance of Student by Web Services based on Annotations 基于注解的Web Services对学生的帮助
Pub Date : 2020-10-07 DOI: 10.1145/3368308.3415414

We focus in our research on the annotative activity of learner because annotation practice is very common and omnipresent. While reading, learner usually uses comments, highlights, circles sections and posts it to annotate the consulted resources. So, we propose an approach of recommendation of web services from the learner's annotative activity to assist him in his learning activates. This process of recommendation is based on two preparatory phases: the phase of modelling learner's personality profile through analysis of annotation digital traces in learning environment realized through a profile constructor module and the phase of discovery of web services which can meet the goals of annotations made by learner via the web service discovery module. The evaluation of these two main modules (web service discovery module and profile constructor module) through empirical studies realized on groups of learners based on the Student's t-test showed significant results
我们之所以把研究重点放在学习者的注释活动上,是因为注释实践是非常普遍和无所不在的。在阅读过程中,学习者通常会使用评论、亮点、圈出部分,并将其贴出来作为参考资料的注解。因此,我们提出了一种从学习者的注释活动中推荐web服务的方法,以帮助学习者的学习活动。该推荐过程基于两个准备阶段:通过分析通过profile constructor模块实现的学习环境中的注释数字痕迹来建模学习者的个性轮廓阶段和通过web服务发现模块发现能够满足学习者标注目标的web服务阶段。基于Student’st检验,通过对学习者群体实现的实证研究对这两个主要模块(web服务发现模块和profile constructor模块)进行了显著性评价

The swift advancement of computerization has resulted in an increased need for individuals skilled in a variety of highly technical fields. This demand is currently inadequately met by the United States? domestic workforce and rural areas are underserved by technological resources and opportunities. Due to political and legislative volatility, fixing this workforce shortage is not feasible. Instead, the long-term solution is the cultivation of domestic workforce with high technical expertise. Therefore, we propose a software engineering curriculum that follows the 2 + 2 educational model to meet the needs of community college students in North Carolina as a model for similar initiatives on a regional and national scale. In this paper, we discuss the current status of computer science and software engineering education in North Carolina community colleges, including the current degree programs and relevant curriculum content. Finally, we discuss our proposed curriculum for a 2 + 2 articulation program in software engineering.
计算机化的迅速发展导致对各种高技术领域的熟练人才的需求增加。这一要求目前没有得到美国的充分满足。国内劳动力和农村地区缺乏技术资源和机会。由于政治和立法的不稳定,解决劳动力短缺问题是不可行的。相反,长期的解决办法是培养具有高技术专长的国内劳动力。因此,我们提出了一个遵循2 + 2教育模式的软件工程课程,以满足北卡罗莱纳州社区大学学生的需求,并将其作为区域和全国范围内类似举措的模型。本文讨论了北卡罗来纳州社区学院计算机科学与软件工程教育的现状,包括目前的学位课程和相关课程内容。最后,我们讨论了我们建议的软件工程2 + 2衔接课程。

The formula for engaging students in a discipline is often a mix of internal and external drives. This poster offers an overview of the solution that our team created as a capstone project, in response to the NASA SUITS Design Challenge. The system became an evolving platform that continues to engage undergraduate and graduate students in Information Technology and related fields.

Baccalaureate IT programs are revisiting their curriculum in response to the ACM/IEEE IT curricular recommendations in the IT2017 report. Consequently, two-year colleges will likely need to update their lower division IT transfer programs as well. IT-Transfer2020 uses the same methodology of competencies as IT2017 and IT2yr2014, and it organizes its 27 essential and 29 supplemental competencies within the ten essential and nine supplemental IT competency domains defined in IT2017. IT-Transfer2020 includes an analysis of congruence between its competencies and the IT2yr2014 learning outcomes to assist institutions looking to offer both transfer and applied two-year IT programs with structuring their course offerings. Two-year programs which follow either IT-Transfer2020 or IT2yr2014 are substantially congruent and would likely only need to differ by one or two courses to prepare students for entry-level positions after two years of study or analyst-level positions upon earning a bachelor's degree. IT-Transfer2020 echoes the IT2017 recommendations regarding mathematics and science content and contains an IT Transfer Articulation Worksheet to facilitate communication between transfer partner institutions as well as assessment rubrics to help with continuous assessment of an IT transfer program's quality. The ACM Committee for Computing Education in Community Colleges invites institutions to highlight their IT transfer program by submitting a program example at ccecc.acm.org/correlations.
为了响应ACM/IEEE在IT2017报告中的IT课程建议,学士学位IT课程正在重新审视他们的课程。因此,两年制大学可能也需要更新他们的低年级IT转学课程。it - transfer2020使用与IT2017和IT2yr2014相同的能力方法,并在IT2017中定义的10个基本和9个补充it能力领域中组织其27个基本和29个补充能力。IT- transfer2020包括对其能力与it2y2014学习成果之间一致性的分析,以帮助那些希望提供转学和应用两年制IT课程的机构构建他们的课程。遵循IT-Transfer2020或it2y2014的两年制课程基本上是一致的,可能只需要一到两门不同的课程,就可以为学生在学习两年后的入门级职位或获得学士学位后的分析师级别职位做好准备。IT- transfer2020响应了IT2017关于数学和科学内容的建议,并包含一个IT转移衔接工作表,以促进转移合作机构之间的沟通,以及评估规则,以帮助持续评估IT转移计划的质量。ACM社区大学计算机教育委员会邀请各大学通过在ccecc.acm.org/correlations上提交程序示例来突出其IT转学课程。
