Photolithography process is one of the most critical in the semiconductor industry since it drives the Moore’s law and the advances in microelectronics in general. Hard constraints on precision, throughput and image quality require software control algorithms and high precision measurements. In such strict environment and requirements, where quality and performance goals need to be met, the optimal design of the measurements is more than necessary. In this paper we propose an Optimal Design of Experiments Algorithm that will enable the process to be able to obtain G-optimal result in a highly competitive time fraction that will ensure at the same time the throughput optimality of the photolithography machines.
光刻工艺是半导体工业中最关键的工艺之一,因为它推动了摩尔定律和微电子技术的发展。对精度、吞吐量和图像质量的硬约束要求软件控制算法和高精度测量。在这样严格的环境和需求中,需要满足质量和性能目标,测量的最佳设计是非常必要的。在本文中,我们提出了一种实验优化设计算法,该算法将使该过程能够在高度竞争的时间分数内获得g -最优结果,同时确保光刻机的吞吐量最优。

In this paper, the concepts and techniques for global graph clustering are examined, or the process of locating related clusters of vertices within a graph. We introduce the construction of a graph clustering technique based on an eigenvector embedding and a local graph clustering method based on stochastic exploration of the graph. Then, the developed implementations of both methods are presented and assessed in terms of performance. In addition, the difficulties associated with assessing clusterings and benchmarking cluster algorithms are explored where PageRank and EigEmbed algorithms are utilized. The experiments show that the EigEmbed outperformed PageRank across all experiments as it detected more communities with the same number of clusters. Ultimately, we apply both algorithms to a real-world graph representing Twitter network and the followers and tweets therein.
本文研究了全局图聚类的概念和技术,即在图中定位相关顶点聚类的过程。介绍了一种基于特征向量嵌入的图聚类技术和一种基于图随机探索的局部图聚类方法。然后,介绍了这两种方法的开发实现,并从性能方面进行了评估。此外,在使用PageRank和EigEmbed算法的情况下,探讨了与评估聚类和对聚类算法进行基准测试相关的困难。实验表明,EigEmbed在所有实验中都优于PageRank,因为它用相同数量的集群检测到更多的社区。最后,我们将这两种算法应用于表示Twitter网络及其追随者和其中的tweet的现实世界图。

The present work aims to lay the foundations for the development of a modern web database application for storage, retrieval, manipulation and visualisation of biological data. The application also offers a data compression service. Although the set of operational requirements will initially be small, the goal is to implement the application following a modern software development methodology, to design with a modern architecture and to rely on a modern stack of technologies, so that our application is easily maintainable and scalable in the future. The latest design patterns will be used in the construction of the application, such as microservices, the model-view-controller technique and three-tier architecture. In the above context, a prototype of the application will be developed, initially in a local development environment, but with the prospect that it will be transferred in the future to a hosting environment so that it is accessible to all.
目前的工作旨在为现代网络数据库应用程序的发展奠定基础,用于生物数据的存储、检索、操作和可视化。该应用程序还提供数据压缩服务。虽然最初的操作需求集很小,但目标是按照现代软件开发方法实现应用程序,使用现代体系结构进行设计,并依赖于现代技术堆栈,以便我们的应用程序在将来易于维护和扩展。最新的设计模式将用于构建应用程序,例如微服务、模型-视图-控制器技术和三层体系结构。在上述上下文中,将开发应用程序的原型,最初是在本地开发环境中开发的,但将来可能会将其转移到托管环境中,以便所有人都可以访问它。

Gait analysis is a methodical study of how people move that can be applied to a range of settings, including sports, rehabilitation and clinical diagnosis. This paper describes a system for tracking the kinetic rehabilitation of hemiplegic patients with a combined use of gait analysis system and wearable devices. The concept is focused on training and extracting individualized knowledge from an intelligent information system during the patient’s stay in the rehabilitation facility. This knowledge can be utilized so that the patient may self-manage their rehabilitation regimen and monitor the improvement of their condition in their own place. Medical experts will then be able to monitor patients’ progress through a cloud-based platform.

The scheduling community has long been interested in educational timetabling. Particularly in academia, since timetabling dictates the day to day operation of Universities, great effort has been exercised to produce high quality schedules. Typically, timetabling problems are NP-Hard and several approaches have been tried in order to generate schedules that satisfy all stakeholders. A number of timetabling competitions have been organized through the last two decades focusing on problems stemming from educational operations. In this paper we use data from two such competitions, ITC2002 and ITC2007 about the post enrollment course timetabling problem. We propose a mathematical model that captures the problem in its entirety and we use it in order to construct feasible solutions initially, and then explore the prospect of optimization. We employ a pre-process stage that attempts to reduce the size of the model and then use an open source solver, that produces solutions in reasonable time for most of the cases. We also propose a simple decomposition of the problem in a day by day basis that can improve the initial feasible solutions.
排课界一直对教育排课感兴趣。特别是在学术界,由于时间表决定了大学的日常运作,因此一直在努力制定高质量的时间表。通常,时间表问题是NP-Hard的,为了生成满足所有涉众的时间表,已经尝试了几种方法。在过去的二十年中,组织了一些时间表竞赛,重点关注教育运作中产生的问题。本文采用了ITC2002和ITC2007这两个关于招生后课程排课问题的竞赛数据。我们提出了一个完整的数学模型,我们用它来构建可行的解决方案,然后探索优化的前景。我们采用一个预处理阶段,试图减少模型的大小,然后使用开源求解器,在合理的时间内为大多数情况生成解决方案。我们还提出了一个简单的逐日分解问题的方法,可以改进最初的可行解决方案。

Driving under the influence of alcohol is one of the most severe and critical problems in every country throughout the world. Driving is a difficult endeavor that demands a high degree of concentration and great visual processing. A system based on the Internet of Things can be utilized to measure drivers’ alcohol level and restrict their operation of motor vehicles. This technology is affordable but has a number of disadvantages, including the requirement for an internet connection, the transfer of data to other organizations, bandwidth and latency constraints, and security concerns. TinyML is an emerging technology that can overcome the aforementioned challenges by performing machine learning models locally and delivering real-time intelligence. In this work, the possibility of developing a TinyML-based system that can detect alcohol and alert the driver was investigated. The experimental findings demonstrate a high degree of accuracy, indicating that the technology under consideration may be utilized to develop compact, intelligent, and inexpensive devices capable of detecting alcohol and alerting the driver in real-time.
酒后驾车是世界上每个国家最严重和最关键的问题之一。驾驶是一项困难的工作,需要高度集中的注意力和出色的视觉处理能力。基于物联网的系统可以用来测量驾驶员的酒精含量,并限制他们驾驶机动车。这种技术经济实惠,但有许多缺点,包括需要互联网连接、向其他组织传输数据、带宽和延迟限制以及安全问题。TinyML是一项新兴技术,可以通过在本地执行机器学习模型并提供实时智能来克服上述挑战。在这项工作中,研究了开发一种基于tinyml的系统的可能性,该系统可以检测酒精并提醒驾驶员。实验结果显示了高度的准确性,表明正在考虑的技术可用于开发紧凑、智能和廉价的设备,能够检测酒精并实时提醒驾驶员。

Augmented Reality (AR) Technologies are gaining considerable attention due to their increased stability and reliability. Combined with the availability of smarter and cheaper devices, like smart-phones and tablets, AR technology greatly helps in enhancing the amount, relevance and ease of access of the available information. At the same pace, Internet of Things (IoT) technologies due to their pervasiveness, are paving the way towards a smarter interconnected world. Several industries, like entertainment, medicine and engineering, have developed and adapted IoT and AR technologies where the enrichment of the physical reality by the information and capabilities offered by AR proved useful for their business. The same approach should and could be the case in the education field. Nevertheless, the usage of IoT and AR technologies is still in its infancy, not following yet the path of many other industry fields. In this paper, after the presentation of contemporary AR and IoT technologies a proposal for utilizing these technologies to teach concepts that are required by the curriculum of the “Informatics Applications” course for the first class of senior high schools in Greece is presented.
增强现实(AR)技术由于其稳定性和可靠性的提高而受到越来越多的关注。与智能手机和平板电脑等更智能、更便宜的设备相结合,增强现实技术极大地帮助提高了可用信息的数量、相关性和易用性。与此同时,物联网(IoT)技术由于其普遍性,正在为更智能的互联世界铺平道路。娱乐、医药和工程等多个行业已经开发并适应了物联网和AR技术,AR提供的信息和功能丰富了物理现实,这对他们的业务很有用。同样的方法应该也可以应用于教育领域。然而,物联网和增强现实技术的使用仍处于起步阶段,尚未遵循许多其他行业领域的道路。在本文中,在介绍了当代AR和IoT技术之后,提出了利用这些技术教授希腊高中一年级“信息学应用”课程所需概念的建议。

Self-sovereign, verifiable, ubiquitous and privacy preserving public entity documents through the use of blockchain technology 通过使用区块链技术,实现自我主权、可验证、无处不在和保护隐私的公共实体文件

Nowadays, citizens tend to use digital services for their interaction with public entities and third party entities. In such cases, they are usually required to present personal public documents, to prove the validity of personal information. Each citizen shares all personal data included in such documents with multiple entities, in order to prove the validity of a subset of those. On top of that, such systems run the risk of documents being forged. In fact, citizens do not have complete control over their personal data management. In this work, a decentralized system for creating and handling documents is presented. We propose a blockchain-based system that enables citizens to actively take part into the creation and management of such documents. Through a granular access control mechanism for the fields of the document, privacy leakage for citizens is minimized. The system enables the seamless interaction between citizens and entities while ensuring privacy and integrity of citizen’s personal data.
如今,公民倾向于使用数字服务与公共实体和第三方实体进行互动。在这种情况下,他们通常被要求出示个人公开文件,以证明个人信息的有效性。每个公民与多个实体共享这些文件中包含的所有个人数据,以证明其中一个子集的有效性。最重要的是,这种系统存在文件被伪造的风险。事实上,公民对个人数据的管理并没有完全的控制权。在这项工作中,提出了一个用于创建和处理文档的分散系统。我们提出了一个基于区块链的系统,使公民能够积极参与这些文件的创建和管理。通过对文档字段的细粒度访问控制机制,将公民的隐私泄露最小化。该系统实现了公民与实体之间的无缝交互,同时确保了公民个人数据的隐私和完整性。

The system enables the seamless interaction between citizens and entities while ensuring privacy and integrity of citizen’s personal data.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"108 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87618669","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}

Our work focuses, on designing and proposing a force estimation sensor system for Geological phenomena data collection and analysis, based on Biomimetic. In this sense, biomimetic term, is used, as proposed by Schmitt in its classical sense, with regatd to the study of nature’s methods, processes and mechanisms. In particular, strain gauge sensors with force sensing resistor (FSR), formate a clustering to estimate ground stress and tension levels, as stated by natures’ mechanisms in earthworms to detect electrical signals. Our sensor system is proposed as a testbed to estimate geological landslide phenomena. Our experimental results from the data collection system is conducted in LabVIEW.
我们的工作重点是设计和提出一个基于仿生的地质现象数据收集和分析的力估计传感器系统。在这个意义上,仿生学术语,被用来研究自然的方法,过程和机制,正如Schmitt在其经典意义上提出的那样。特别是,带有力感电阻(FSR)的应变计传感器,形成一个集群来估计地应力和张力水平,正如蚯蚓检测电信号的自然机制所述。我们的传感器系统被提出作为评估地质滑坡现象的试验台。数据采集系统的实验结果是在LabVIEW中进行的。
