W. Terouzi, F. Kzaiber, A. Oussama
In order to remain competitive in a world where digital tools are dominant, the industry must continue to modernize its production tools, evolve its business models, its organization, and redesign its design and marketing modes. Thus, the industry of the future must be innovative, competitive, efficient, safe and attractive. It connects employees, production machines, service providers, and the territory. It knows how to respond to the economic, technological, organizational, environmental and societal challenges of the 21st century. The main objective of this work is to optimize and evaluate the efficiency of a new sustainable and digital analytical approach. This analytical technique, developed based on IR-ATR spectroscopy linked to multivariate analysis, was applied to samples of small green peas coming from very close geographical areas. The obtained results clearly show the robustness and the efficiency of the technique to be an analytical approach which meets the requirements of the future industry in a digital world.

COVID-19 is one of the most dangerous pandemics in human history. First emerged in Wuhan, China, in December 2019, it has become a concern to all countries of the world. This virus only needs a short distance to spread rapidly between humans, and even if we could locate all the infected individuals, this would not solve the problem. The real solution is to identify all the people who have come in contact with the virus carrier. This paper is a study on online monitoring, intelligent assisted diagnosis, and treatment assistance for covid-19 in terms of early identification, social distancing, and quarantine. While focusing on wireless healthcare networks, the internet of things, and cloud computing. A federated or hybrid approach leverages the strengths and mitigates the weaknesses of both Data Medical Technology and IOT to detect and alert people who have been exposed to covid-19.
COVID-19是人类历史上最危险的大流行病之一。2019年12月在中国武汉首次出现,已成为世界各国关注的问题。这种病毒只需要很短的距离就能在人与人之间迅速传播,即使我们能找到所有受感染的人,这也不能解决问题。真正的解决办法是找出所有与病毒携带者接触过的人。本文从早期发现、保持社交距离、隔离等方面对新型冠状病毒肺炎在线监测、智能辅助诊断和治疗辅助进行研究。同时专注于无线医疗网络、物联网和云计算。联合或混合方法利用数据医疗技术和物联网的优势并减轻其弱点,以检测和提醒已接触covid-19的人。

Hmamed Hala, Cherrafi Anass, B. Rajaa, Benghabrit Youssef, J. Garza‐Reyes
The world cannot overstate the importance of road traffic safety, as it is an integral part of life. As consequence, there has been recently a marked advance in the use of machine learning techniques for the assessment of road traffic crashes. This study inspects the use of machine learning to build road safety model, by recognizing many factors that lead to accident severity, related to drivers, infrastructures, vehicles…. Different classification algorithms have been conducted to predict the severity of accidents based on real dataset, Decision Tree, Naives Bayes, Support Vector Machine, K-Nearest Neighbors, and Multilayer Perceptron. We compared the performance of each algorithm using the accuracy and the Receiver Operating Characteristic (ROC), to ensure that the proposed model provides stable and reliable predictive decisions. The finding revealed that the most accurate models are Support Vector Machine, K-Nearest Neighbors and Multilayer Perceptron with respectively 91% 92% 94% against the others models.

Toward an assessment model of the impact of ICT Strategic Alignment Maturity and Information Systems Success on innovation and performance 信息通信技术战略一致性成熟度和信息系统成功对创新和绩效影响的评估模型
Salah Jadda, Nawfal Acha, Hafid Barka
There are several models for evaluating the contribution of Information and Communication Technologies (ICT) to the performance of organizations, while very little research has focused on the contribution of ICTs to innovation. Knowing that this is crucial for performance, Information Technology could improve the ability to detect innovation opportunities, and ICT Strategic Alignment (SA) could increase innovation. However, organizations can be confined to a particular way of “doing business” if they are not flexible in aligning their ICTs with business, which can negatively influence innovation. Likewise, if the Information System (IS) is not satisfactory, it would not positively impact innovation. This article aims to propose a conceptual model of the determinants of the maturity of the ICT Strategic Alignment and the quality of organizations' IS to assess the contribution of these two variables to innovation. This model was developed following a review of the literature which determined the factors for evaluating the strategic alignment maturity as well as the factors used to assess the Information System Success, innovation, and performance within organizations.
目前有几种评估信息通信技术(ICT)对组织绩效贡献的模型,而关注ICT对创新贡献的研究却很少。认识到这对绩效至关重要,信息技术可以提高发现创新机会的能力,信息通信技术战略协调(SA)可以增加创新。然而,如果组织不能灵活地将其信通技术与业务结合起来,就可能被局限于一种特定的"开展业务"的方式,这可能对创新产生负面影响。同样,如果信息系统(IS)不令人满意,它也不会对创新产生积极影响。本文旨在提出信息通信技术战略一致性成熟度和组织信息系统质量决定因素的概念模型,以评估这两个变量对创新的贡献。该模型是在回顾文献后开发的,该文献确定了评估战略一致性成熟度的因素,以及用于评估组织内信息系统成功、创新和绩效的因素。

Contribution to improving the conditions of access to very high speed 5G internet for online education in developing African countries 为改善非洲发展中国家使用超高速5G网络进行在线教育的条件做出贡献
L. Ndiaye, Samba Diouf, Kéba Gueye, S. Ouya, G. Mendy
ICT are experiencing a boom in the evolution of mobile networks. Today the advent of 5G offers major benefits in all sectors such as education, health, agriculture etc. 5G allows very high speed access, very low latency but also good bandwidth. This will result in faster access with a much smoother data processing turnaround time for the services offered. Developing African countries must prepare to face these opportunities despite their meager resources. In this article we use the robustness of free software like open5gs to set up a latest generation mobile network with an implementation of innovative services. This shows the relevance of having a reliable new generation mobile network infrastructure at a lower cost. This article is based on a mobile network infrastructure whose radio and network access parts are software because today it is possible to emulate mobile networks with computing, in particular NFVs. It will allow the developing country of Africa to understand the importance of having its own network, especially in the context of the covid-19 pandemic where all activities have become virtual. In this context, activities such as distance learning require internet access and good bandwidth.

Amri Omar, Fri Mohamed, Msaaf Mohammed, Belmajdoub Fouad
The neural network training algorithms or optimizers had already been a lively research topic for several years because they are a crucial part of the neural network structure. That is why; the choice of the training algorithm that can be used to optimize a neural network is one of the most important phases in the neural network's building. Therefore, it is necessary to choose the most adequate optimization algorithm for the desired application, in order to achieve a model that can deal with the best performances. In these papers, we are interested in the training algorithms used in supervised learning. Therefore, we present an overview and a comparative study between the most common algorithms employed to justify the choice of an optimizer, which can deal with high performances.

The Sebou Watershed, contains an area of 40000 km2, it represents a third of the surface flows of Morocco it is characterized by a varied topography from North to South, their extent and their lithology. This variation has a strong effect on the distribution of precipitation and the flow regimes of rivers. The current study is an attempt to delineate the hydrodynamic of the different aquifers and watercourses of this Watershed. In the Rif in the north of the basin, the slopes are steep, with significant hydrographic networks, characterized by a torrential water volume, on the other hand in the south by water tables which allows the retention of a very large quantity of water of precipitation and runoff.

Hardware Architecture of EKF-SLAM's Prediction Stage and its FPGA Implementation EKF-SLAM预测台硬件架构及FPGA实现
Slama Hammia, A. Hatim, A. Bouaaddi
Simultaneous Localisation and Mapping (SLAM) allows robot equipped with sensors to map its environment while locating itself in space. However, due to the computational complexity of SLAM algorithms, researches are focusing on reducing computation complexity and developing embedded systems on low resources and low complexity platforms to achieve real time requirements. Field-Programmable Gate Array (FPGA) is an attractive real-time platform for SLAM systems as they are low power and high performance. In this work, we present an EKF-SLAM (Extended Kalman Filter SLAM) prediction stage hardware architecture design and implementation on FPGA. We implemented the design using an FPGA Cyclone 2. The design can reach up to 114 MHz and uses 3507 logic elements, and it respect the real time requirements.
同时定位和测绘(SLAM)允许机器人装备传感器,在空间定位自己的同时绘制环境地图。然而,由于SLAM算法的计算复杂度,研究的重点是降低计算复杂度,在低资源、低复杂度的平台上开发嵌入式系统,以达到实时性要求。现场可编程门阵列(FPGA)以其低功耗、高性能的特点成为SLAM系统的实时平台。在这项工作中,我们提出了一个EKF-SLAM(扩展卡尔曼滤波SLAM)预测阶段的硬件架构设计和FPGA实现。我们使用FPGA Cyclone 2实现了该设计。该设计最高可达114mhz,使用3507个逻辑元件,符合实时性要求。

An overview on machine learning methods for ECG Heartbeat Arrhythmia Classification 心电图心律不齐分类的机器学习方法综述
Mohamed Sraitih, Y. Jabrane, Abdelghafour Atlas
The automated classifiers can assist cardiology experts in diagnosing heart-linked illnesses with the initial and well-predicted results of classified ECG signals and data of subjects. This work serves as a review of various research works on ECG data and signals classification using supervised machine learning approaches. We presented and reviewed, the performance and the strategies used to classify cardiac arrhythmias using five widely used classifiers, Support vector machine (SVM), Random forest (RF), Decision three (DT), Naïve Bayes (NB), and K-nearest neighbour (KNN). And we discussed a variety of limitations and revealed that there is still area for increase in the classification's performance, specially by minimizing the preprocessing and feature extraction step which can cause an important computational cost and different accuracy outcomes. Such a coordinated research review allows scientists to merge an unobstructed view on some aspects of ECG classification for the identification of the research issues unmet so far. We plan to consider the obstacles discussed and some limitations to further raise the classification performance of the automated classifiers for the applicability of such solutions in clinical diagnosis.
自动分类器可以帮助心脏病专家通过分类心电图信号和受试者数据的初始和良好预测结果来诊断心脏相关疾病。这项工作是对使用监督机器学习方法的ECG数据和信号分类的各种研究工作的回顾。我们介绍并回顾了使用支持向量机(SVM)、随机森林(RF)、决策三(DT)、Naïve贝叶斯(NB)和k近邻(KNN)这五种广泛使用的分类器对心律失常进行分类的性能和策略。我们讨论了各种限制,并揭示了分类性能仍有提高的空间,特别是通过最小化预处理和特征提取步骤,这可能会导致重要的计算成本和不同的精度结果。这样一个协调的研究综述使科学家能够对ECG分类的某些方面进行无阻碍的合并,以确定迄今为止尚未解决的研究问题。我们计划考虑所讨论的障碍和一些限制,以进一步提高自动分类器的分类性能,使这些解决方案在临床诊断中的适用性。
