Fuzzy logic inference system based quality prediction model for HD HEVC video streaming over wireless networks 基于模糊逻辑推理系统的无线网络高清HEVC视频流质量预测模型
Farouk Boumehrez, A. Sahour, N. Doghmane
Checking the quality of video transmitted over a wireless network is critical to improving network performance. In this paper, we evaluate the HEVC/H.265 video coding standard in terms of quantization parameters (QP), video content, and the degradation impact of transmission channels on quality. Additionally, studying Quality of Service (QoS) and Quality of Experience (QoE) will allow us to study multimedia applications in wireless ad hoc networks. This paper presents (1) the performance evaluation of QP value variation for different video contents on HEVC/H265, (2) the investigation of the impact of packet loss and jitter on the QoS of transmission sequences, and (3) the fuzzy logic model proposed to evaluate the performance of transmission sequences. The results show that using different QP values can counteract the effects of packet loss and jitter and improve the received video quality.
检查通过无线网络传输的视频质量对于提高网络性能至关重要。在本文中,我们评估了HEVC/H。265视频编码标准在量化参数(QP)、视频内容、传输信道退化等方面对质量的影响。此外,研究服务质量(QoS)和体验质量(QoE)将使我们能够研究无线自组织网络中的多媒体应用。本文提出(1)在HEVC/H265上对不同视频内容的QP值变化进行性能评价;(2)研究丢包和抖动对传输序列QoS的影响;(3)提出模糊逻辑模型对传输序列性能进行评价。结果表明,采用不同的QP值可以抵消丢包和抖动的影响,提高接收到的视频质量。

TDMA-CADH Cross-Layer Approach for IoT Performance Aspects 物联网性能方面的TDMA-CADH跨层方法
Raid Boudi, Z. Aliouat, Chirihane Gherbi
A network in which the items use a variety of different technologies is known as the Internet of Things (IoT). Wireless sensors networks are the most common objects in the IoT. It has numerous low-power sensors that detect environmental conditions, perform data processing. These sensors work together to perform complex tasks via wireless communication. In this context, we have proposed TDMA CADH (TDMA Cross-layer Approach Aware Delay in Heterogeneous WSN) approach based on routing information. The goal is to ensure the constraint of energy consumption and therefore, network lifetime. The main concept is to minimize delays and optimize distribution channel. In order to validate the improvements made by our approach, we carried out a simulation using a network simulator NS3 (Network Simulator NS3), in which the performances of our proposal are evaluated and compared with the already existing approaches, namely, Rand-LO (Random Leaves Ordering), Depth-LO (Depth Leaves Ordering) and Depth-ReLO (Depth Remaining Leaves Ordering).

Meriem Mouzai, Faiza Farhi, Zaid Bousmina, Aouache Mustapha, Ilyes Keskas
Retinal fundus images are images of color representing the inner surface of the human eye; they provide the anatomical structure of retinal blood vessels. Early diagnosis of eye-related diseases is crucial in order to take precautionary protocols to prevent major vision loss. In this study, a Machine learning-based approach for blood vessel segmentation is pro-posed. To this end, two different supervised Machine learning algorithms were implemented to analyze their performance and efficiency on blood vessel segmentation. These two algorithms are based on U-net modeling and ResNet50. A comparative analysis between the developed models and the state-of-the-art was conducted to determine a suitable solution for accurate blood vessel segmentation.

Graph Convolutional Networks for Designing Collaborative Filtering-Based Health Recommender Systems 基于协同过滤的健康推荐系统的图卷积网络设计
B. Boudaa, Imen Bestani, Noureddine Benadjrouda
Recommender systems provide useful item suggestions (products or services) to users as part of their decision-making processes. The effectiveness of recommender systems is now clearly confirmed in various fields of application (e.g., YouTube, Amazon, Facebook, ResearchGate). In the literature, many research works have addressed the application of recommendations in the field of health in what are called health recommender systems (HRS). HRS is an innovative alternative when it comes to providing information to help doctors in the diagnosis/treatment of diseases, as well as helping patients with recommendations on how to maintain their well-being. However, the proposed development approaches in this field are limited to traditional models that lack the accuracy and effectiveness, which are vital in healthcare. This paper presents a design model for collaborative filtering-based health recommender systems using graph neural networks (GNN) via its promising Graph Convolutional Network (GCN) architecture. In this model, the convolution layer works with a simplified and efficient GCN algorithm named LightGCN. GCN-based methods are among the new cutting-edge approaches in recommender systems, and LightGCN has proven its superiority in recommendation accuracy.
推荐系统为用户提供有用的项目建议(产品或服务),作为他们决策过程的一部分。推荐系统的有效性现在在各个应用领域得到了明确的证实(例如,YouTube, Amazon, Facebook, ResearchGate)。在文献中,许多研究工作已经解决了在所谓的健康推荐系统(HRS)的卫生领域的建议的应用。HRS是一个创新的选择,当涉及到提供信息,以帮助医生诊断/治疗疾病,以及帮助患者建议如何保持他们的健康。然而,该领域提出的开发方法仅限于缺乏准确性和有效性的传统模型,这在医疗保健中至关重要。本文提出了一种基于协同过滤的健康推荐系统的设计模型,该系统采用了图神经网络(GNN)及其有前途的图卷积网络(GCN)架构。在该模型中,卷积层使用了一种简化且高效的GCN算法LightGCN。基于遗传神经网络的推荐方法是推荐系统中新的前沿方法之一,LightGCN已经证明了其在推荐准确性方面的优势。

Cloud Computing Interoperability : An overview 云计算互操作性:概述
Messaouda Ayachi, Hassina Nacer, Hachem Slimani
At present, cloud computing has attracted a serious deal of research interest and attention in multiple domains. One of the core challenges in this environment is to achieve interoperability among heterogeneous cloud service providers (heterogeneous resources, APIs (Application Programming Interface), SLA(Service-level agreement) policy, etc.) to keep up with the increasing demand of cloud services and the growing requirements of user’s applications. For that, we provide in this paper an overview of the existing approaches and proposed solutions. In this setting, we aim to clarify: Who has posed the Cloud Computing Interoperability (CCI) problem? What does CCI mean? When and Why CCI is needed? Where does CCI problem arise? And the key question that is: How to resolve CCI problem? For this latter, we propose a taxonomy where we distinguish between the considered factors before resolving the CCI problem, and the obtained characteristics of the proposed solutions after resolving the CCI problem. Then we study existing works of CCI according to this proposed taxonomy, where we have generated three graphs allowing us to discuss CCI solution approach VS consumer-centric, CCI solution architecture VS consumer-centric, and CCI solution approach VS CCI solution type. We have concluded that: 1) the application service model is more highlighted in the literature then the management and platform levels, 2) the provider-centric solutions use generally model based approaches and are deployed as middleware or brokers, 3) the user-centric solutions are based on the adapting methodologies and deployed as brokers, 4) the hybrid solutions are based on the adapting methodologies and offer standard or broker architectures, 5) the type of CCI solution in model based approaches is mainly corresponding to framework products, 6) the final product of adapting methodologies can be a service or a library type.
目前,云计算已经在多个领域引起了广泛的研究兴趣和关注。这种环境下的核心挑战之一是实现异构云服务提供商(异构资源、api(应用程序编程接口)、SLA(服务水平协议)策略等)之间的互操作性,以跟上云服务日益增长的需求和用户应用程序日益增长的需求。为此,我们在本文中概述了现有的方法和提出的解决方案。在这种情况下,我们的目标是澄清:谁提出了云计算互操作性(CCI)问题?CCI是什么意思?何时以及为什么需要CCI ?CCI问题出现在哪里?关键问题是:如何解决CCI问题?对于后者,我们提出了一种分类法,在解决CCI问题之前,我们将考虑的因素与解决CCI问题后提出的解决方案所获得的特征区分开来。然后,我们根据提出的分类法研究CCI的现有作品,其中我们生成了三个图表,允许我们讨论CCI解决方案方法与以消费者为中心,CCI解决方案架构与以消费者为中心,以及CCI解决方案方法与CCI解决方案类型。我们的结论是:1)应用程序服务模型在文献中比管理和平台级别更突出,2)以提供者为中心的解决方案通常使用基于模型的方法并作为中间件或代理部署,3)以用户为中心的解决方案基于自适应方法并作为代理部署,4)混合解决方案基于自适应方法并提供标准或代理体系结构,5)基于模型方法的CCI解决方案类型主要对应于框架产品;6)适应方法的最终产品可以是服务类型或库类型。

Improving Self-Adaptation by Combining MAPE-K, Machine and Deep Learning 结合MAPE-K、机器和深度学习提高自适应能力
Sabah Lecheheb, Soufiane Boulehouache, Said Brahimi
Monitoring, Analyzing, Planning, and Execution share knowledge and build a favorable approach in the form of a loop (MAPE-K). However, this proposed reference model is not efficient for large self-adaptations. Moreover, the failure of the analyzer component to keep up with the current expansion of data is one of the reasons that making the MAPE-K loop consumes a lot of time and resources. We suggest a hybrid learning dataflow design for the analysis phase that combines Machine and Deep Learning techniques to enhance the accuracy of the Analyzer component in less time.

A Survey on Self-adaptation Planning Optimization Techniques 自适应规划优化技术综述
Roumaysa Bousselidj, Soufiane Boulehouache, Said Brahimi
Self-adaptation planning is a challenging task being time and resource consuming. It can be affected by multiple sources of uncertainty as it deals with frequently changing contexts. In addition, it requires real-time information, which is unpredictable at design time, to offer high quality adaptation solution. To deal with these issues, a wide range of studies proposed techniques to optimize the adaptation planning process regarding two aspects namely: planning timeliness and the quality of the provided adaptation solution. However, these two criteria are conflicting in nature i.e. improving the performance of the planning in terms of response time deteriorates the quality of the adaptation solution and vice-versa. Therefore, the adaptation research community witnesses the emergence of multiple studies of which the ultimate goal is to obtain a tradeoff between the two aspects. In this paper, we aim to highlight the key design objectives that affect the planning design and implementation. Moreover, we present the planning optimization techniques proposed in the literature and categorize them to give an understandable view of this specific area of Self-Adaptive Systems (SASs).
自适应规划是一项具有挑战性的任务,耗时耗力。在处理频繁变化的上下文时,它可能受到多种不确定性来源的影响。此外,它需要实时的信息,而这些信息在设计时是不可预测的,以提供高质量的自适应解决方案。针对这些问题,广泛的研究从规划及时性和提供的适应方案质量两个方面提出了优化适应规划过程的技术。然而,这两个标准在本质上是相互冲突的,即在响应时间方面提高规划的性能会降低适应解决方案的质量,反之亦然。因此,适应研究界出现了多种研究,其最终目的是在两者之间取得权衡。在本文中,我们旨在强调影响规划设计和实施的关键设计目标。此外,我们提出了文献中提出的规划优化技术,并对它们进行了分类,以便对自适应系统(SASs)的这一特定领域给出一个可理解的观点。

Real-Time Detection of Vehicle License Plates Numbers 实时检测车辆牌照号码
A. Amrouche, Nabil Hezil, Youssouf Bentrcia, Ahcène Abed
Object Detection (OD) techniques have emerged as the key to dealing with the most complex computer vision problems in recent years. Vehicle License Plate Detection (VLPD) is the most important stage of any vehicle license plate recognition system (VLPR) because changes in its size, orientation, color, and background, contrast, and resolution have a direct impact on the system’s robustness and accuracy. The purpose of this paper is to present an object detector for detecting vehicle license plates in real-world scenes. We developed a new dataset of vehicle license plate numbers and used it to train our custom model. In YOLO-v3 layers, we decreased the number of classes to one in order to improve the detector. When we evaluated the system, we achieved precision, recall, and overall accuracy metrics of 0.95, 0.96, and 92.83 percent, respectively.
近年来,目标检测技术已成为处理最复杂的计算机视觉问题的关键。车牌检测是车牌识别系统中最重要的阶段,车牌的大小、方向、颜色、背景、对比度和分辨率的变化直接影响到系统的鲁棒性和准确性。本文的目的是提出一种用于真实场景中车牌检测的目标检测器。我们开发了一个新的车辆车牌号码数据集,并用它来训练我们的定制模型。在YOLO-v3层中,我们将类的数量减少到一个,以改进检测器。当我们对系统进行评估时,我们分别达到了0.95、0.96和92.83%的精密度、召回率和总体准确度指标。

The purpose of this paper is to present an object detector for detecting vehicle license plates in real-world scenes. We developed a new dataset of vehicle license plate numbers and used it to train our custom model. In YOLO-v3 layers, we decreased the number of classes to one in order to improve the detector.

Towards a model driven approach for integrating NWN models in CINCO 在CINCO中整合NWN模型的模型驱动方法
Amel Dembri, M. Redjimi
In this paper, we propose a model driven approach to facilitate the integration of Nets within Nets (NWN) modeling language in CINCO modeling tool. Despite that, NWN has a sophisticated modeling-simulation tool called Renew, moving NWN models from a platform to another has been a challenge for programmers. The development of our tool is heavily benefits from being implemented with CINCO; a full generation of the application code is provided, a powerful tool is developed with a few efforts and facilities are provided to add semantic to the platform. Combine formal method with a sophisticated model driven tool simplifies the prototypical of domain specific systems, promotes the interoperability capabilities between different technologies and assists designer in the validation of the correctness of the modeled system.
在本文中,我们提出了一种模型驱动的方法来促进CINCO建模工具中网中网(NWN)建模语言的集成。尽管如此,NWN拥有一个名为Renew的复杂建模仿真工具,将NWN模型从一个平台转移到另一个平台对程序员来说是一个挑战。我们的工具的开发在很大程度上得益于CINCO的实施;提供了一个完整的应用程序代码生成,一个功能强大的工具,并提供了向平台添加语义的工具。将形式化方法与复杂的模型驱动工具相结合,简化了特定领域系统的原型,提高了不同技术之间的互操作性,并帮助设计者验证建模系统的正确性。
