With the arrival of the most recent coronavirus pandemic, it was a must to find solutions to detect this dangerous virus. Analyzing X-ray images was among the exploited techniques to control this disease. However, the doctor's subjectivity in analyzing X-rays was the first obstacle in detecting this virus accurately. Applying new deep learning techniques to x-ray images can be a potential solution to reduce this subjectivity. This paper aims to conduct a comparative study between six different CNN architectures (VGG16, VGG19, Inception, Xception, DenseNet, and ChexNet) for COVID-19 detection from X-rays. The obtained results based on the transfer learning strategy confirm the efficiency of the VGG 16, where its achieved 98.69 % of accuracy on the COVID-19 Radiography Dataset.
随着最新冠状病毒大流行的到来,必须找到检测这种危险病毒的解决方案。分析x射线图像是控制这种疾病的常用技术之一。然而,医生在分析x射线时的主观性是准确检测这种病毒的第一个障碍。将新的深度学习技术应用于x射线图像可能是减少这种主观性的潜在解决方案。本文旨在对六种不同的CNN架构(VGG16、VGG19、Inception、Xception、DenseNet和ChexNet)进行COVID-19 x射线检测的比较研究。基于迁移学习策略获得的结果证实了VGG 16的有效性,其在COVID-19放射学数据集上的准确率达到了98.69%。

Networks are becoming more sophisticated with time, and stability issues have become more prevalent. In general, the problem of voltage instability increases as various energy sources, such as solar, wind, etc., are connected to the grid. The most notable issue is grid control. Controlling the flow of reactive power in the grid is essential for optimizing power system performance. When a system fails, is overloaded, and the voltage varies, unbalanced reactive power occurs. Connecting a device to the transmission line that can inject or absorb reactive power, depending on the system requirements, can restore reactive power balance. D-FACTS (Distributed Flexible AC Transmission System) is one of the most useful sources of reactive power. Distributed Static Var Compensation (D-SVC) and Distributed Static Synchronous Compensation (D-STATCOM) are the famous compensation methods of the D-FACTS families. The influence of D-SVC and D-STATCOM on increasing the dynamic voltage stability of distribution networks with distributed wind generation and variable load is investigated in this paper. Simulations using MATLAB/Simulink were used to observe the dynamic behavior of both devices. This article provides a comparison of simulation results between grids without D-FACTS and grids with D-FACTS.
随着时间的推移,网络变得越来越复杂,稳定性问题变得越来越普遍。一般来说,随着各种能源(如太阳能、风能等)接入电网,电压不稳定问题也会增加。最显著的问题是网格控制。控制电网无功潮流是优化电力系统性能的关键。当系统发生故障、过载、电压变化时,会产生不平衡的无功功率。根据系统需要,在输电线上接入能注入或吸收无功功率的设备,可以恢复无功功率的平衡。分布式柔性交流输电系统是最有用的无功电源之一。分布式静态无功补偿(D-SVC)和分布式静态同步补偿(D-STATCOM)是D-FACTS系列中著名的两种补偿方法。本文研究了D-SVC和D-STATCOM对提高分布式风力发电和变负荷配电网动态电压稳定性的影响。利用MATLAB/Simulink进行仿真,观察两种器件的动态行为。本文提供了不带D-FACTS和带D-FACTS网格的仿真结果比较。

This study is an attempt to contribute to the design, development, and production of a myoelectric hand prosthesis. This prosthetic device is controlled by an EMG signal captured using surface electrodes on a stump's muscle. The realization of customized electronics allowed us to operate the prosthesis's five fingers with five servo motors. Force sensors on the tip of each finger made this prosthesis tactile, allowing the intelligent system in place to grab or drop an object as the amputee desired.

Detection and classification of vehicle types is one of the most important applications in field of road safety. In this paper, we propose a deep learning process to detect and classify vehicles by using Single shot Detector (SSD) for detection and Di-lated Multi-Column Convolutional Neural Network (DMCCNN) for classification. Rather than using a fixed-scale convolutional layer, the second model we use is capable to extract features from various scales of an image employing different dilated filters to improve the performance classification, especially for similar-looking vehicles like Suv and Sedan. An embedded Raspberry Pi vehicle detection and classification system is developed using a built-in Pi camera. The results are comparable with desktop-based results in the literature yielding an accuracy of 95.93 % on BIT dataset.

Challenges in Real-time Scheduling for Energy Harvesting Embedded Systems 嵌入式能量采集系统实时调度的挑战
Pub Date : 2022-11-02 DOI: 10.1109/EDiS57230.2022.9996470

The recent and rapid development of the Internet of Things (IoT’) leads to the need for embedded devices that comprise one or more resource-constrained computing elements and sensors. Energy Harvesting (EH) technology provides the ability for any low-power embedded device to operate thanks to the generation of electricity from the energy available in the device's immediate surroundings such as light or motion. Energy neutrality is the central requirement of autonomous real-time computing systems that should be designed to correctly function for long times with no possible manual intervention to charge or replace batteries. Unfortunately, most of environmental energy sources are fluctuating and not controllable. It means that a stable power supply cannot be relied upon that makes challenging the issue of compliance with hard real-time constraints. Specific power management and scheduling solutions have to be conceived in order to prevent energy starvation and guarantee real-time responsiveness. Task scheduling should take into account not only the timing parameters of the deadline constrained tasks such as worst-case execution times but also energy consumptions, profile of the energy source and capacity of the energy storage unit. The classical greedy scheduler Earliest Deadline First (EDF) or Rate Monotonic (RM) used in battery powered devices should be revisited for this novel operational context. This keynote discusses the state of the art as well as our findings in real-time scheduling and dynamic processor management for autonomous embedded systems. Short biography: Maryline Chetto is currently a full professor in computer engineering with Nantes Université, France and researcher with CNRS. She received the degree of Docteur de 3ème cycle in control engineering and the degree of Habilitee á Diriger des Recherches in Computer Science from the University of Nantes, France, in 1984 and 1993, respectively. From 1984 to 1985, she held the position of Assistant professor of Computer Science at the University of Rennes, while her research was with the Institut de Recherche en Informatique et Systemics Aléatoires (IRISA), Rennes. In 1986, she returned to Nantes and has been from 2002 a full professor with the University of Nantes. She is conducting her research at Laboratoire des Sciences du Numérique de Nantes (LS2N, UMR CNRS no 6004) in the Real Time System group.
物联网(IoT)最近的快速发展导致对嵌入式设备的需求,这些设备包括一个或多个资源受限的计算元件和传感器。能量收集(EH)技术为任何低功耗嵌入式设备提供了运行的能力,这要归功于从设备的直接环境(如光或运动)中可用的能量发电。能量中立性是自主实时计算系统的核心要求,该系统应被设计为在不需要人工干预充电或更换电池的情况下长时间正常运行。不幸的是,大多数环境能源是波动的,不可控的。这意味着不能依赖稳定的电力供应,这使得符合硬实时约束的问题具有挑战性。必须构思特定的电源管理和调度解决方案,以防止能源短缺并保证实时响应。任务调度不仅要考虑受最后期限约束的任务的最坏情况执行时间等时序参数,还要考虑能量消耗、能源分布和储能单元容量等因素。在这种新的操作环境中,应该重新审视电池供电设备中使用的经典贪婪调度程序最早截止日期优先(EDF)或速率单调(RM)。本主题讨论了自主嵌入式系统在实时调度和动态处理器管理方面的最新进展。简介:Maryline Chetto目前是法国南特大学计算机工程专业的正教授,也是法国国家科学研究中心的研究员。她分别于1984年和1993年在法国南特大学获得控制工程博士学位和计算机科学研究博士学位。从1984年到1985年,她担任雷恩大学计算机科学助理教授,同时她的研究在雷恩信息与系统研究所(IRISA)进行。1986年,她回到南特,自2002年起担任南特大学正教授。她在实时系统组的Nantes numsamrique科学实验室(LS2N, UMR CNRS no 6004)进行研究。

Creating an Edge-to-Cloud Computing Continuum: Status and Perspective 创建边缘到云计算连续体:现状和观点
Pub Date : 2022-11-02 DOI: 10.1109/EDiS57230.2022.9996495
Fulvio Risso
The creation of a computing (and storage) continuum that spans across multiple infrastructures has been recently proposed with the aim at breaking the barriers of current cloud computing silos. While the potential of this vision is clear, such as possible energy efficiency improvements, application transparency, better quality of service, the problems in realizing this vision are challenging. In fact, the necessity (a) to consider WAN latencies, network bottlenecks and possible network outages, (b) to support different administrative boundaries (hence, security), (c) to define novel orchestration algorithms are only a first portion of the ingredients required to create this continuum. Even more important are the necessity to achieve an economic sustainability and the necessity to migrate applications to the new paradigm, which are often not considered by the current research efforts. Starting from the experience achieved in the open-source liqo.io project, this talk will introduce the potentials and the challenges in the creation of the edge-to-cloud computing continuum, and it will present what are the major blocking points along our way.
最近有人提议创建跨越多个基础设施的计算(和存储)连续体,目的是打破当前云计算竖井的障碍。虽然这一愿景的潜力是明确的,例如可能的能源效率改进、应用程序透明度、更好的服务质量,但实现这一愿景的问题是具有挑战性的。事实上,需要(a)考虑WAN延迟、网络瓶颈和可能的网络中断,(b)支持不同的管理边界(因此是安全性),(c)定义新的编排算法,这些只是创建这个连续体所需成分的第一部分。更重要的是实现经济可持续性的必要性和将应用程序迁移到新范式的必要性,这些通常没有被当前的研究工作所考虑。从在开源liqo中获得的经验开始。IO项目,本演讲将介绍在创建边缘到云计算连续体的潜力和挑战,并将介绍我们前进道路上的主要障碍。

Visual sensor networks (VSN) have a wide range of applications in real-world scenarios. As a result, deployment, coverage, energy harvesting, and many other challenges are tough to deal with. The cost of deploying VSNs to cover targets with particular constraints, such as targets coverage, barrier walls and capture quality, are explored in this study. For a Mixed Integer mathematical formulation, an exact and an approximation solution were presented. Exact resolution of appropriate size instances is difficult because this is an NP-hard problem. Several studies attempt to solve these issues by providing approximation methods, heuristics, and metaheuristics. The Particle Swarm Optimization (PSO) metaheuristic is a well-known based metaheuristic which we adopt in this paper. While dealing with difficult optimization problems, this technique provided excellent results. According to experiments and results, the proposed PSO method performed efficiently in both small and large instances of the problem.
视觉传感器网络(VSN)在现实场景中有着广泛的应用。因此,部署、覆盖、能量收集和许多其他挑战都很难处理。本研究探讨了部署vns覆盖具有特定约束条件的目标的成本,如目标覆盖、屏障墙和捕获质量。对于一个混合整数数学公式,给出了精确解和近似解。准确地解决适当大小的实例是困难的,因为这是一个np困难问题。一些研究试图通过提供近似方法、启发式和元启发式来解决这些问题。粒子群优化(PSO)元启发式算法是本文采用的一种知名的基于元启发式算法。在处理困难的优化问题时,该技术提供了极好的结果。实验和结果表明,所提出的粒子群算法无论在大实例还是小实例中都能有效地解决问题。

While dealing with difficult optimization problems, this technique provided excellent results. According to experiments and results, the proposed PSO method performed efficiently in both small and large instances of the problem.","PeriodicalId":288133,"journal":{"name":"2022 3rd International Conference on Embedded & Distributed Systems (EDiS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129993104","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}

Beekeeping or modern Apiculture is the act of rearing beehives for the purpose of cultivating honey, a nutrient that is also used in several industries, and its derivatives. Smart apiculture is a relatively new domain seeking to improve modern beekeeping using novel technologies. In this paper we seek to shed light on both the intricacies of modern beekeeping, the used technologies in intelligent apiculture and survey the challenges and issues that face them as a basis for building better solutions. The aim is to offer a full-fledged and summarized survey of the domain thus opening the door for future solution adaptation and/or proposal.

Blockchain-Based Conditional Privacy-Preserving Authentication Mechanism for Vehicular Fog Networks 基于区块链的车载雾网络条件隐私保护认证机制

With the emergence of vehicular fog networks (VFC), the transportation system is increasingly improving traffic management and road safety. However, secure and reliable data transmissions have become crucial to ensure a better quality of service (QoS). In this direction, several conditional privacy-preserving authentication schemes have been proposed. In the literature, most schemes suffer from key escrow problems. Even the schemes that reside in this concern, they have the problem of storage and centralization; since the trusted authority (TA) must register for each vehicle all the pseudonyms that will be used. Likewise, the vehicle must store all the pseudonyms and the keys that will be used in its memory. To address all these problems, we propose a conditional privacy-preserving authentication mechanism for vehicular fog networks that allows the vehicle to generate its own private/public keys with its pseudonym when needed, and without being stored at the TA. The proposal uses elliptic curve cryptography for authentication and blockchain technology for storing registration and authentication results. The performance evaluation and security analysis show that our proposed mechanism provides improved security features compared to related work with reduced computational and communication overhead. Our mechanism has reduced the registration time of vehicles to only 0.024 ms.
随着车雾网络(VFC)的出现,交通系统正日益改善交通管理和道路安全。然而,安全可靠的数据传输已成为确保更好的服务质量(QoS)的关键。在这个方向上,已经提出了几种条件隐私保护认证方案。在文献中,大多数方案都存在关键的托管问题。即使是存在于这个问题中的方案,它们也存在存储和集中的问题;因为受信任的权威机构(TA)必须为每辆车注册将要使用的所有假名。同样,车辆必须在其内存中存储将使用的所有假名和密钥。为了解决所有这些问题,我们为车载雾网络提出了一种有条件的隐私保护认证机制,该机制允许车辆在需要时使用其假名生成自己的私钥/公钥,而无需存储在TA中。该提案使用椭圆曲线加密进行身份验证,使用区块链技术存储注册和身份验证结果。性能评估和安全分析表明,与减少计算和通信开销的相关工作相比,我们提出的机制提供了改进的安全特性。我们的机制将车辆登记时间缩短至0.024毫秒。
