On-Site and Remote Crowdsourcing of Accessibility Data for People with Mobility Impairments: A Case Study in Zurich’s District 1 行动障碍人士无障碍数据的现场和远程众包:苏黎世1区的案例研究
Lina Witzel, Sophy Chhong, H. Hutter, Alireza Darvishy
Collecting accurate accessibility data systematically for pathways is a time-consuming task that typically requires expert knowledge. However, it is a prerequisite to enable reliable and trustworthy accessible routing. The development of Capture & Go, a mobile application to report barriers for people with mobility impairments, facilitates the on-site collection of crowdsourced accessibility data. Several other mapping tools contain accessibility data, although they have not been developed explicitly for this purpose. In contrast to Capture & Go, they allow data collection to be performed remotely. Using quantitative and qualitative approaches, we analyzed several such applications and examined their efficiency in capturing barriers in a case study of District 1 in Zurich. The remotely collected data was compared to the data of the barriers captured on-site using Capture & Go. Overall, the remote tools were less efficient than Capture & Go in terms of effort, coverage, and accuracy of the barriers, as well as usability.
系统地收集路径的准确可达性数据是一项耗时的任务,通常需要专业知识。但是,这是启用可靠和可信的可访问路由的先决条件。Capture & Go是一款移动应用程序,用于报告行动障碍人士的障碍,它的开发促进了现场收集众包无障碍数据。其他几个映射工具包含可访问性数据,尽管它们没有为此目的明确开发。与Capture & Go相比,它们允许远程执行数据收集。使用定量和定性方法,我们分析了几个这样的应用程序,并以苏黎世1区为例研究了它们在捕获障碍方面的效率。将远程收集的数据与现场使用Capture & Go捕获的障碍物数据进行比较。总的来说,远程工具在工作、覆盖范围、障碍的准确性以及可用性方面不如Capture & Go有效。

Bulgaria's Digital Transformation 保加利亚的数字化转型
L. Bower
For over three decades, Bulgaria has been advancing the level of technology in the country. The strategy has evolved from e-government into digital transformation. In the beginning, the country’s e-Government program was focused primarily on developing and upgrading infrastructure elements and main systems. However, the existing regulatory framework was able to accommodate e-Government, but it did not stimulate it. In addition, difficult to achieve high efficiency achieve high efficiency due to a lack of a systematic approach to e-Government development. Some agencies had progressed significantly in implementing electronic administrative services, but in general, e-services were limited.The government forged a strategic framework to implement e-government, and a new e-government agency was established to guide the process. Tis strategy has been successfully implemented: the government has gone paperless, citizens have mobile access to government services, and schools receive curriculum materials electronically. e-Government system, part of an end-to-end solution to provide e-Government services The main components of Bulgaria’s e-Government infrastructure include portals, networks, eIdentificatin/e/Authorization, and knowledge management. The legal framework includes legislation, freedom of information, data protection/privacy, e-commerce, e-communications, and e-procurement.Bulgaria has obtained significant benefits from this program. In particular, it has contributed to a tangible reduction of the administrative burden on citizens and business. Going paperless by itself has saved hundreds of tons of paper and humdreds of thousands of dollars annually. In addition, government processes have been optimized, and systems are more reliable and secure.The program continues with Digital Bulgaria 2025. This program has a vision beyond government operations and seeks to bring the benefits of digital technology to all sectors of the economy and society. The goal is to create an environment to foster the widespread use of information and telecommunications technologies (ICT), along with new technologies for businesses and citizens. Continued progress in e-government is an important part of the program, as well as modernizing education, improving the digital ICT skills of the workforce, and increasing the number of highly qualified ICT specialists. Significant benefits are expected from the implementation of this strategy.It encompasses achievements so far and the new European strategic and programming guidelines for achieving a smart, sustainable and inclusive digital growth. The goal is widespread implementation of intelligent solutions in all areas of the economy and society, and modernizing information and communications technologies (ICT
三十多年来,保加利亚一直在提高本国的技术水平。该战略已从电子政务演变为数字化转型。一开始,该国的电子政务计划主要侧重于发展和升级基础设施要素和主要系统。然而,现有的规管架构能够容纳电子政府,但并没有促进电子政府的发展。此外,由于缺乏系统的电子政务发展途径,难以实现高效率的实现。有些机构在实施电子行政服务方面取得了重大进展,但总的来说,电子服务是有限的。政府制定了实施电子政务的战略框架,并成立了一个新的电子政务机构来指导这一进程。这一战略已成功实施:政府已实现无纸化,公民可以通过移动设备获得政府服务,学校以电子方式接收课程材料。保加利亚电子政务基础设施的主要组成部分包括门户、网络、电子认证和知识管理。法律框架包括立法、信息自由、数据保护/隐私、电子商务、电子通信和电子采购。保加利亚从这一方案中获得了重大利益。特别是,它有助于切实减轻公民和企业的行政负担。无纸化本身每年就节省了数百吨纸张和数十万美元。此外,政府流程得到优化,系统更加可靠和安全。该计划将在数字保加利亚2025年继续进行。该计划的愿景超越了政府运作,并寻求将数字技术的好处带给经济和社会的所有部门。目标是创造一种环境,促进信息和电信技术的广泛使用,同时为企业和公民提供新技术。电子政务的持续发展,以及教育现代化、提高劳动力的数字信息通信技术技能和增加高素质信息通信技术专家的数量,都是该计划的重要组成部分。预计实施这一战略将带来重大利益。它涵盖了迄今为止取得的成就,以及为实现智能、可持续和包容性数字增长而制定的新的欧洲战略和规划指南。目标是在经济和社会的各个领域广泛实施智能解决方案,并实现信息和通信技术(ICT)的现代化

New technologies sustainability: monitoring and evaluation of results of interventions for the promotion of cultural heritage and the human landscape 新技术的可持续性:监测和评估促进文化遗产和人文景观的干预措施的结果
P. Dantonio, C. Fiorentino, Vincenzo Nunzio Scalcione, Francesca Vera Romano, Francesco Toscano
The relationship between the development of technologies and the history of the cultural and agricultural landscape is linked to the concepts of "cultural landscape", understood as a space in continuous construction that changes with the change of individual, collective, social and cultural relationships of the inhabitants of the territory, or of the "cultural inhabitants", citizens who are producers of culture, rather than users. A vision of the "future as an open place" emerges, understood as a place of usability and sharing of all human, material and immaterial productions.Technologies, within a similar perspective, are presented as the historical evolution of téchne, whose degree of development today allows an extension of the level of human action.This study, in agreement with the scientific literature based on the use of recently developed digital models, demonstrates that the mainly agricultural territory of Basilicata, historically the site of complex social relations, has created a traditional rural society in which the concept of neighborhood and the spatial connotation also had the symbolic value of sharing knowledge and practices, relationships based on inclusiveness and sustainability. The diffusion of 5G technology is generating important cultural transformations. What used to be the neighborhood community in Matera (IT) - also following the activities launched with the CTEMT project and the social consequences of the Covid-19 pandemic - is now becoming a virtual community for sharing knowledge and practices , beliefs and values, including the use and management of cultural heritage, which takes place through the network, and therefore using applications that promote a transformative intervention of the landscape, such as to make it functional to human needs, and, at the same time, sustainable with respect to the perpetuation of ecosystem relationships.The diffusion of 5G technology, is generating important cultural transformations. What in the past was, in Matera (IT), the neighbourhood community - also as a result of the activities launched with the CTEMT project and the social consequences of the Covid-19 pandemic - now becomes a virtual community, sharing knowledge and practices, beliefs and values, including the use and management of cultural heritage, occurs through the network with the use of applications that promote accessibility and sustainability in both the urban and agricultural landscape. As argued by the International Union for Conservation of Nature (IUCN), the attention to the dynamic conservation of the landscape should not be placed so much to the "culture itself" or to the "nature itself" but rather to the relationship between these two dynamic components has been established, but also from the holistic mentioned many times, attentive to the values of identity and comforted by the knowledge and decoding of the intangible heritage, from which we deduce the active role, shared soc
技术的发展与文化和农业景观的历史之间的关系与“文化景观”的概念联系在一起,文化景观被理解为一个持续建设的空间,随着领土上居民的个人、集体、社会和文化关系的变化而变化,或者“文化居民”,作为文化生产者而不是使用者的公民。“未来是一个开放的地方”的愿景出现了,被理解为一个可用性和共享所有人类、物质和非物质产品的地方。从类似的角度来看,技术被视为人类的历史演变,其发展程度今天允许人类行动水平的扩展。本研究与基于使用最新开发的数字模型的科学文献一致,表明巴西利卡塔的主要农业领域,历史上是复杂社会关系的场所,创造了一个传统的农村社会,在这个社会中,邻里概念和空间内涵也具有共享知识和实践的象征价值,以及基于包容性和可持续性的关系。5G技术的传播正在产生重要的文化转型。马泰拉曾经的邻里社区(IT)——也是在CTEMT项目启动的活动和2019冠状病毒病大流行的社会后果之后——现在正在成为一个虚拟社区,通过网络分享知识和实践、信仰和价值观,包括文化遗产的使用和管理,因此使用应用程序促进景观的变革性干预。例如,使其能够满足人类的需要,同时在生态系统关系的永续方面具有可持续性。5G技术的传播正在产生重要的文化转型。在马泰拉(IT),过去的邻里社区——也是由于CTEMT项目开展的活动和Covid-19大流行的社会后果——现在成为了一个虚拟社区,通过使用促进城市和农业景观可达性和可持续性的应用程序,通过网络分享知识和实践、信仰和价值观,包括文化遗产的使用和管理。正如国际自然保护联盟(IUCN)所主张的那样,对景观动态保护的关注不应过多地放在“文化本身”或“自然本身”上,而应放在这两个动态组成部分之间已经建立起来的关系上,而且要从多次提到的整体性出发,关注身份的价值,并以非物质遗产的知识和解码为安慰,从中我们推断出积极的作用。共同的社会行为、知识传播机制和跨代意识也得益于复杂而迷人的用途、传统、仪式和仪式,这些都是有意识地管理景观及其文化的重要工具。人工智能的自觉使用是人文主义与技术良性关系的具体体现。对于生物多样性来说,它是对物种,特别是本地物种的认可的支持,它允许人们在文化上认识自己,并在生物多样性中找到属于社区和景观的集体和文化。因此,由于新技术的使用,生物多样性成为一个地区知识和实践的历史人类学档案,新技术成为保护文化遗产的有力工具。

The Course Glancer - Leveraging Interactive Visualization for Course Selection 课程浏览-利用交互式可视化课程选择
Christian Spletter, Martin J. Eppler
Lifelong learning requires the consistent and continued development of one’s knowledge, skills, and competencies. However, due to the extensive choice of courses offered at today’s institutions of higher learning, students face a risk of choice overload in their selection of (elective) courses. As current findings in choice overload literature do not refer to student samples in educational settings nor do they consider the use of interactive visualization formats, the use of interactive visualization in higher education organizations seems a promising way to support course selection that fits educational needs. All the more as previous visualization approaches to overcome table-based visualizations or online course catalogues primarily aim at communicating curricular content and structure to different university stakeholders, while disregarding students. We thus introduce our work-in-progress on an interactive visualization tool called the Course Glancer. The Course Glancer supports students’ decision-making ability when confronted with a variety of learning offers while taking electives of a bachelor’s degree program in business administration. The tool provides support for gaining an overview on all available courses and their categories, and for rapidly comparing course alternatives. In doing so, it can help to clarify course preferences and finally to foster students’ confidence of not having overlooked an important course option. This is in line with Shneiderman’s information-seeking mantra as a must-have for effective cognitive processing: Overview first, zoom and filter, then details-on-demand. We use this mantra in connection with Norman’s usability principles of discoverability, affordances, feedback, constraints, mapping, and consistency. An example of how we use constraints is that course comparison is limited to juxtaposing two courses only. This functionality considers latest evidence from using eye-tracking studies that revealed that human beings tend to distribute their attention in an unbalanced manner and focus mainly on the two options that seem the most promising alternatives. To enrich the empirical research on choice overload, we plan to focus on psychological effects in the use of the Course Glancer. These include subjective, moderating factors (e.g., decision style) and behavior-related measures. The latter refer to subjective states (choice satisfaction, decision regret, decision confidence) or behavioral outcomes (e.g., choice deferral, option selection). Beyond these, group-related effects should also be analyzed in future research, for example, if interacting with our tool can stimulate information exchange processes within expert groups of higher education organizations (e.g., in the context of accreditation procedures or curriculum planning).
终身学习需要一个人的知识、技能和能力的持续发展。然而,由于当今高等院校提供的课程选择范围广泛,学生在选择(选修)课程时面临着选择过载的风险。由于目前关于选择超载的研究结果并没有涉及教育环境中的学生样本,也没有考虑使用交互式可视化格式,因此在高等教育机构中使用交互式可视化似乎是一种很有前途的方式,可以支持适合教育需求的课程选择。更重要的是,之前的可视化方法克服了基于表格的可视化或在线课程目录,主要目的是将课程内容和结构传达给不同的大学利益相关者,而忽视了学生。因此,我们介绍了我们正在开发的交互式可视化工具,称为Course Glancer。课程浏览器支持学生在选修工商管理学士学位课程时,面对各种学习机会时的决策能力。该工具提供了对所有可用课程及其类别的概述,以及快速比较课程选择的支持。这样做,它可以帮助澄清课程偏好,并最终培养学生的信心,没有忽视一个重要的课程选择。这与施耐德曼的信息寻求咒语是一致的,它是有效认知处理的必备条件:首先概述,放大和过滤,然后按需查看细节。我们将这个咒语与Norman的可用性原则(可发现性、可视性、反馈、约束、映射和一致性)联系在一起。我们如何使用约束的一个例子是,课程比较仅限于并列两个课程。这项功能考虑了眼球追踪研究的最新证据,这些研究表明,人类倾向于以一种不平衡的方式分配注意力,主要集中在两个看起来最有希望的选择上。为了丰富关于选择过载的实证研究,我们计划关注课程浏览者在使用过程中的心理效应。这些包括主观的、调节因素(例如,决策风格)和与行为相关的措施。后者是指主观状态(选择满意、决策后悔、决策自信)或行为结果(如选择延迟、选择)。除此之外,在未来的研究中还应该分析群体相关的影响,例如,如果与我们的工具交互可以刺激高等教育组织专家组内部的信息交换过程(例如,在认证程序或课程规划的背景下)。

E. Conceicao, Mª Inês Conceição, Mª Manuela Lúcio, João Gomes, H. Awbi
In this work a DSF system (Double Skin Facade) is used to improve the thermal comfort level that the occupants are subjected in an experimental chamber. The DSF system, build with three unities, is equipped in a south facade of the experimental chamber. The study, made in winter conditions, uses the solar radiation to heated the air, injected in the occupied space with 6 people, to improve the thermal comfort conditions. The experimental chamber is build with wood and isolating material. The DSF system is build with two glass façades, equipped with 15 lamellas. This system, subjected to solar radiation, is connected to the interior with a duct system connected with two ventilators. The numerical study consider a software that simulates the building and the DSF thermal response. The numerical model, that considers buildings with complexes topologies, uses energy and mass balance integral equations for the opaque surfaces, transparent surfaces and internal air. The software also considers the solar radiation simulator, the radiative and convective coefficients evaluation, the glass radiative properties and the thermal comfort and internal air quality simulator. In accordance with the obtained results the thermal comfort level, using the PMV (Predicted Mean Vote), during the occupation time, in general, is in accordance with the international standards.

Framework of Future Industrial Worker Characteristics 未来产业工人特征框架
Päivi Heikkilä, S. Aromaa, Hanna Lammi, T. Kuula
The ways of working are changing in the manufacturing industry due to new technologies and the merging of physical and virtual environments (e.g., Industry 4.0 [1], Metaverse [2]). Already, work tasks are changing from physical and routine tasks towards intellectual and social activities which often include the use of ICT tools [3]. The pandemic has changed attitudes and ways of working towards hybrid arrangements and therefore, expectations related to flexibility in work may become more pertinent also for manufacturing workers [4]. Novel technologies are being developed to support the industrial worker in the future [5], which can be called augmentation or empowerment of workers [6-8].The World Manufacturing Forum has identified the top ten skills that will be needed in future manufacturing work [9]. In our study, we wanted to add understanding of the skills and characteristics needed in future industrial work and present the results in a format that would support designers of technological tools to consider the perspective of future workers. Our goal was to create a framework of worker characteristics that could guide the design of technological tools to assist workers in work tasks requiring new skills and characteristics. To understand the transformation of work and to create a framework, we conducted a literature review and 10 expert interviews, focusing on the ways emerging technologies are expected to change the nature of industrial work. Based on the results, a framework of future industrial worker characteristics (FIW) was created. The applicability of the framework was tested by applying it in a European research project that develops software solutions for the context of modern, flexible, and data-rich manufacturing. Altogether, 19 novel software solutions that are being developed to support industrial work were mapped using the characteristics of the framework. The mapping experiment provided understanding of the relevance of the worker characteristics and the ways to support them in practice.According to the FIW framework, future industrial work will require smarter operations, which emphasizes worker capabilities in terms of mastering complexity, solving problems, making proactive decisions, and considering sustainability. Transforming work requires resilience that can be strengthened by capabilities such as creativity, the ability to lead oneself, flexibility, and continuous learning. Being interactive will be a vital part of work and can be fostered by communication, collaboration, supporting inclusiveness and interculturality, as well as sharing a safety-oriented mindset and work practices. In addition, health and well-being will have a central role in the future work. A healthy worker can be characterized as feeling motivated, balanced, capable, and focused.The FIW framework can be used by designers and industrial companies to guide the design and acquirement of novel technology solutions to su
由于新技术以及物理和虚拟环境的融合(例如,工业4.0 [1],Metaverse[1]),制造业的工作方式正在发生变化。工作任务已经从体力和日常任务转变为智力和社会活动,其中往往包括使用信息和通信技术工具。大流行病改变了人们对混合安排的态度和工作方式,因此,对工作灵活性的期望可能也更适用于制造业工人。新技术正在发展,以支持未来的产业工人,这可以被称为增强或赋予工人权力[6-8]。世界制造业论坛已经确定了未来制造业工作中需要的十大技能。在我们的研究中,我们希望增加对未来工业工作所需的技能和特征的理解,并以一种格式呈现结果,以支持技术工具的设计者考虑未来工人的观点。我们的目标是创建一个工人特征的框架,可以指导技术工具的设计,以帮助工人完成需要新技能和特征的工作任务。为了理解工作的转变并创建一个框架,我们进行了文献综述和10位专家访谈,重点关注新兴技术有望改变工业工作性质的方式。在此基础上,构建了未来产业工人特征(FIW)框架。通过在一个欧洲研究项目中应用该框架来测试其适用性,该项目为现代、灵活和数据丰富的制造业开发软件解决方案。总共有19个正在开发的支持工业工作的新型软件解决方案使用框架的特征进行了映射。映射实验提供了对工人特征相关性的理解以及在实践中支持它们的方法。根据FIW框架,未来的工业工作将需要更智能的操作,这强调了工人在控制复杂性、解决问题、做出积极决策和考虑可持续性方面的能力。转变工作需要弹性,而弹性可以通过创造力、自我领导能力、灵活性和持续学习等能力来加强。互动将是工作的重要组成部分,可以通过沟通、协作、支持包容性和跨文化,以及分享以安全为导向的思维方式和工作实践来培养。此外,健康和福祉将在今后的工作中发挥核心作用。一个健康的员工可以被描述为感觉积极、平衡、有能力和专注。设计师和工业公司可以使用FIW框架来指导设计和获取新的技术解决方案,以支持未来工业工作的特征,总的来说,从工人技能和特征的角度增加对工业工作转型的理解。在未来,最好将该框架应用于其他研究案例和行业环境中,以找出可能的开发需求和将框架嵌入设计或评估过程的方法。参考文献bbb10 Henning Kagermann, Wolfgang Wahlster和Johannes Helbig. 2013。实施工业4.0战略倡议的建议:确保德国制造业的未来。82.[2]朴相民、金永嘉,2022。元verse:分类、组件、应用程序和开放的挑战。IEEE Access [3]Eurofound。2018. 2030年欧洲就业工资和任务概况。2023年Gartner[4]。2023年的未来工作趋势。可用:gartner.com/en/articles/9-future-of-work-trends-for-2023[2023年2月15日访问]。[5]大卫·罗梅罗,约翰·斯塔雷,托尔斯滕·韦斯特,奥维迪乌·诺兰,彼得·伯努斯,Åsa Fast-Berglund和多米尼克·戈雷基。2016。迈向操作员4.0类型:以人为中心的第四次工业革命技术视角。2016年第46届计算机与工业工程国际学术会议。[10]Eija Kaasinen, Franziska Schmalfuß, Cemalettin Özturk, Susanna Aromaa, Menouer Boubekeur, Juhani Heilala, Päivi Heikkilä, Timo Kuula, Marja Liinasuo和Sebastian Mach。2020。通过运营商4.0解决方案增强和吸引产业工人。计算机与工业工程139,105678。[7]Roope Raisamo, Ismo Rakkolainen, Päivi Majaranta, Katri Salminen, Jussi Rantala和Ahmed Farooq. 2019。人类增强:过去,现在和未来。国际人机研究学报,131,131-143。[8]弗朗西斯科·贝蒂和托马斯·博纳,2022。增强劳动力:赋予人们权力,改变制造业。世界制造业论坛。2019。未来制造业的技能。

Prevention of Work-Related Musculoskeletal Disorders supported by Artificial Intelligence 人工智能支持下的与工作相关的肌肉骨骼疾病预防
Firdaous Sekkay
In the industry 4.0 era, industrial production is designed to be more efficient, more flexible, and with higher quality. Besides, it is characterized by greater automation and computerization. However, in the industrial field, workers are still involved in many jobs requiring them to lift and move heavy items and other production activities that expose them to the associated risk factors for developing work-related musculoskeletal disorders (WMSDs). In physical ergonomics, studies have shown potential for preventing WMSDs through artificial intelligence (AI). In this regard, this literature review aims to establish the current state of art regarding the use of AI to reduce the risk of developing WMSDs. A literature review was carried out in two databases, and through the combination of keywords, 188 articles were found. Twenty-eight papers were retrieved and analyzed based on dimensions related to WMSDs risk factors, ergonomic criteria, and AI applications.

Identification of airspaces with increased coordination effort based on radar data 根据雷达数据加强协调工作以识别空域
Sören Holzenkamp, M. Jung
Artificial intelligence (AI) systems can be beneficial in various disciplines such as medicine, space travel or air transport. The Project “Collaboration of aviation operators and AI systems” (LOKI) of the German Aerospace Center (DLR) aims to develop guidelines for a human-centered design of communication and also collaboration between users and AI systems. The Project focusses on areas of activity in air traffic management where operators work together collaboratively. To identify the potential for AI support of air traffic controllers as well as pilots, information about the coordination effort of aircrafts for air traffic controllers in the European airspace is needed. The aim of this paper is to identify areas of increased coordination effort for air traffic controllers based on four-dimensional radar data. Here, AI could be advantageous for air traffic management.For this purpose, we used flight tracking data from a network of ADS-B receivers. The data includes all flights in the upper European airspace in September 2019 and has a resolution of one data point per minute. First, the data was pre-processed and visualized. Afterwards three criteria for detecting possible communications between pilots and controllers were applied to the data. The first criterion examines the frequency of climbs and descents in the course of a flight. The second one analyses the changes in flight direction in the flight trajectories. The third criterion identifies aircraft that fall below a minimum vertical and lateral separation between each other. The Python programming language and various data science libraries were used to apply the criteria to the data. The result is a spatio-temporal cadastre with entries of possible controller communication which shows that relatively large areas with a high coordination effort for air traffic management controllers exist in Europe. These areas are mostly located in Central Western Europe and UK, but also in Spain, Portugal and Russia, inter alia. In reality, the coordination effort is probably even higher than in this model. Against this background, it is reasonable to conclude that the potential for using AI in air traffic management is rather high and that the use of AI can be beneficial for ATM operations in Europe.
人工智能(AI)系统可以在医学、太空旅行或航空运输等各个学科中发挥作用。德国航空航天中心(DLR)的“航空运营商和人工智能系统的协作”项目(LOKI)旨在制定以人为中心的通信设计以及用户和人工智能系统之间的协作指南。该项目侧重于空中交通管理活动领域,运营商可以在这些领域协同工作。为了确定人工智能支持空中交通管制员和飞行员的潜力,需要有关欧洲空域空中交通管制员的飞机协调工作的信息。本文的目的是根据四维雷达数据确定空中交通管制员增加协调努力的领域。在这方面,人工智能可能对空中交通管理有利。为此,我们使用了来自ADS-B接收器网络的航班跟踪数据。该数据包括2019年9月欧洲上空的所有航班,分辨率为每分钟一个数据点。首先,对数据进行预处理和可视化。随后,三个检测飞行员和管制员之间可能通信的标准被应用于数据。第一个标准是考察飞行过程中爬升和下降的频率。第二部分分析了飞行轨迹中飞行方向的变化。第三个标准是指飞机之间的垂直和横向距离低于最小距离。Python编程语言和各种数据科学库用于将标准应用于数据。结果是一个包含可能的管制员通信条目的时空地籍图,这表明欧洲存在相对较大的空中交通管理管制员高度协调努力的区域。这些地区主要位于西欧中部和英国,但也包括西班牙、葡萄牙和俄罗斯等。在现实中,协调工作可能比这个模型还要高。在这种背景下,我们可以合理地得出结论,在空中交通管理中使用人工智能的潜力相当高,人工智能的使用可以有利于欧洲的ATM操作。

Tutorial: Conceptualizing intelligence amplification in human-centred AI applications using the design canvas 教程:使用设计画布在以人为中心的AI应用程序中概念化智能放大
Jean Paul Sebastian Piest, Maria Eugenia Iacob, Marcel Johanna Theodoor Wouterse
Designing applications that enhance the cognitive abilities of their users is complex and requires involvement of stakeholders from different disciplines. The intelligence amplification design canvas aims to ease and support initial design processes. Currently, a step-by-step tutorial for practitioners is lacking. Extending earlier work regarding the organization of a design canvas workshop, the objective of this paper is to provide such a tutorial. Leveraging the comprehensive design approach for intelligence amplification from earlier work, participants of this tutorial will detail a self-defined idea or existing application using the 13 elements of the intelligence amplification design canvas in four short iterations. Following its four design principles, participants use the intelligence amplification design canvas to emphasize and define human-centred design aspects, the embodiment in the form of a software agent, the use of data driven approaches and computational intelligence, and incorporation of human in the loop. This way, the tutorial contributes to the initiation of new human-centred AI projects as well as the analysis and improvement of existing applications. Furthermore, this tutorial aspires to form a group of researchers and practitioners to collaboratively develop and evaluate human-centred AI applications and case studies. The tutorial can be planned as a half-day or full-day session depending on the target audience. The tutorial requires a room for 4-8 pairs of workshop participants, a large screen or beamer, and laptop for the tutorial presentation. The intelligence amplification design canvas can best be printed on A3 paper for each participant and can be filled in using a pen or post-its. The target audience of the tutorial includes, but is not limited to practitioners, researchers, and students active in the fields of computer science, information systems research, systems design and engineering and human-computer interaction.
设计增强用户认知能力的应用程序是复杂的,需要来自不同学科的利益相关者的参与。智能放大设计画布旨在简化和支持初始设计过程。目前,缺乏针对从业者的分步教程。扩展早期关于设计画布研讨会组织的工作,本文的目的是提供这样一个教程。利用早期工作中智能放大的综合设计方法,本教程的参与者将在四个简短的迭代中使用智能放大设计画布的13个元素详细介绍自定义的想法或现有的应用程序。遵循其四个设计原则,参与者使用智能放大设计画布来强调和定义以人为中心的设计方面,以软件代理的形式体现,使用数据驱动方法和计算智能,以及将人纳入循环。通过这种方式,本教程有助于启动新的以人为中心的人工智能项目,以及分析和改进现有应用程序。此外,本教程渴望形成一组研究人员和实践者,共同开发和评估以人为中心的人工智能应用和案例研究。根据目标受众的不同,教程可以计划为半天或全天。该教程需要一个可容纳4-8对研讨会参与者的房间,一个大屏幕或投影仪,以及用于教程演示的笔记本电脑。每个参与者最好将智能放大设计画布打印在A3纸上,并可以使用钢笔或便利贴填写。本教程的目标读者包括但不限于从事计算机科学、信息系统研究、系统设计与工程以及人机交互领域的从业人员、研究人员和学生。

Data Analysis for the Projection of Flexible Composite Materials to Naval Transport Scenarios 柔性复合材料在海上运输场景中的投影数据分析
Alexandra Gabriela Ene, C. Mihai, M. Jomir, Constantin Jomir
Accidental spills of oil or other types of hydrocarbons represent a problem of utmost importance, but, in the situation where a multi-criteria approach to the phenomenon is desired, it is necessary a quickly intervention for mitigate the effects of their spread, and for isolation, collection, transportation and storeage for reprocessing. In case of oil recovering, trapped oil can be pumped out to holding tanks (shuttles) for transporting to shore. The functional characteristics required for naval transport are represented by the: operational in strong sea currents oil spill recovery (min. 4bf), transport and storage (at min. 2kt); rapid response in an emergency (possibility to be used in max. 1 h in conjunction with oil spill recovery equipment: vessel, booms, skimmers etc). Although it could be considered that the tear resistance on the longitudinal and transversal system for any composite structure including a textile matrix based on woven structure, could be influenced by the physical-mechanical characteristics of the textile reinforcement (the nature of the raw material and the diameter of the threads), in the situation of usage the flexible elements (narrow fabrics) to join the panels, the correlation between the above mentioned parameters could be made only by mathematical approaches. This assumption is based on the fact that in the textile field, the mechanism of deformation of threads and implicitly of planar structures is not fully explained (as in the field of constructions). The paper presents the analysis of the data collection, with the help of multiple regression, each of the 6 dependent variables (tear resistance values assessed according to three accredited methods in longitudinal and transversal systems) being modeled with the help of 5 independent variables (resistance to maximum force breaking strength, knot resistance, loop for two types of sewing thread and the breaking resistance of composite material fabrics). For the 3500 values obtained as a result of the experiments carried out, the initial hypotheses were related to: i) the experience matrix (u observations for q variables) is fixed, it is not stochastic, and the number of experiences is greater than the number of variables and ii ) the matrix of measured values for the independent variables has linearly independent columns, so it forms a basis of a q-dimensional space. The main problems followed were related to the model parameters, measurement errors, adjustment precision and the choice of the prediction model.

石油或其他类型碳氢化合物的意外泄漏是一个极其重要的问题,但是,在需要对该现象采取多标准方法的情况下,有必要迅速采取干预措施,以减轻其扩散的影响,并对其进行隔离、收集、运输和储存,以便进行后处理。在石油回收的情况下,被困的石油可以被泵出到储罐(穿梭船),以便运输到岸上。海上运输所需的功能特征表现为:在强海流中作业,溢油回收(最少4bf),运输和储存(最少2kt);在紧急情况下的快速反应(可能在最多使用。1小时与溢油回收设备(船、围油栏、撇油器等)配合使用。尽管可以认为,任何复合材料结构(包括基于机织结构的纺织基体)的纵向和横向系统的抗撕裂性可能受到纺织增强材料的物理机械特性(原材料的性质和螺纹的直径)的影响,但在使用柔性元件(窄织物)连接面板的情况下,上述参数之间的相关性只能通过数学方法来确定。这一假设是基于这样一个事实,即在纺织领域,线的变形机制和隐含的平面结构没有得到充分的解释(如在建筑领域)。本文对收集的数据进行分析,借助多元回归,将6个因变量(根据纵向和横向系统中三种认可的方法评估的抗撕裂值)中的每一个变量与5个自变量(抗最大力断裂强度,抗结性,两种缝纫线的环和复合材料织物的抗断裂性)进行建模。对于实验所得的3500个值,初始假设涉及:1)经验矩阵(q个变量的u个观测值)是固定的,不是随机的,经验的数量大于变量的数量;2)自变量的实测值矩阵具有线性独立的列,因此它构成了一个q维空间的基。接下来的主要问题与模型参数、测量误差、平差精度和预测模型的选择有关。所建立的概率模型解释了因变量变化的55-80%,因此需要引入以下类型的附加变量(例如,对于含有45/55% PES/对芳纶基体的复合材料):织物的图案、经纬纱密度、涂层厚度。此外,为t检验获得的值确定了多变量回归方程中预测因子的重要性。
{"title":"Data Analysis for the Projection of Flexible Composite Materials to Naval Transport\u0000 Scenarios","authors":"Alexandra Gabriela Ene, C. Mihai, M. Jomir, Constantin Jomir","doi":"10.54941/ahfe1002940","DOIUrl":"https://doi.org/10.54941/ahfe1002940","url":null,"abstract":"Accidental spills of oil or other types of hydrocarbons represent a problem of\u0000 utmost importance, but, in the situation where a multi-criteria approach to the\u0000 phenomenon is desired, it is necessary a quickly intervention for mitigate the effects\u0000 of their spread, and for isolation, collection, transportation and storeage for\u0000 reprocessing. In case of oil recovering, trapped oil can be pumped out to holding tanks\u0000 (shuttles) for transporting to shore. The functional characteristics required for naval\u0000 transport are represented by the: operational in strong sea currents oil spill recovery\u0000 (min. 4bf), transport and storage (at min. 2kt); rapid response in an emergency\u0000 (possibility to be used in max. 1 h in conjunction with oil spill recovery equipment:\u0000 vessel, booms, skimmers etc). Although it could be considered that the tear resistance\u0000 on the longitudinal and transversal system for any composite structure including a\u0000 textile matrix based on woven structure, could be influenced by the physical-mechanical\u0000 characteristics of the textile reinforcement (the nature of the raw material and the\u0000 diameter of the threads), in the situation of usage the flexible elements (narrow\u0000 fabrics) to join the panels, the correlation between the above mentioned parameters\u0000 could be made only by mathematical approaches. This assumption is based on the fact that\u0000 in the textile field, the mechanism of deformation of threads and implicitly of planar\u0000 structures is not fully explained (as in the field of constructions). The paper presents\u0000 the analysis of the data collection, with the help of multiple regression, each of the 6\u0000 dependent variables (tear resistance values assessed according to three accredited\u0000 methods in longitudinal and transversal systems) being modeled with the help of 5\u0000 independent variables (resistance to maximum force breaking strength, knot resistance,\u0000 loop for two types of sewing thread and the breaking resistance of composite material\u0000 fabrics). For the 3500 values obtained as a result of the experiments carried out, the\u0000 initial hypotheses were related to: i) the experience matrix (u observations for q\u0000 variables) is fixed, it is not stochastic, and the number of experiences is greater than\u0000 the number of variables and ii ) the matrix of measured values for the independent\u0000 variables has linearly independent columns, so it forms a basis of a q-dimensional\u0000 space. The main problems followed were related to the model parameters, measurement\u0000 errors, adjustment precision and the choice of the prediction model. The built\u0000 probabilistic models explain between 55-80% of the variation of the dependent variable,\u0000 so it would be indicated to introduce additional variables (e.g. for composite material\u0000 with 45/55% PES/p-aramida matrix) of the type: pattern of the fabric, yarn density in\u0000 warp and weft, coating thickness.
