Learning platforms provide educational tools and strategies to impart the necessary knowledge, skills and attitudes to learners. Effectiveness and the ability to deliver tangible benefits to learners largely depend on how they are designed, delivered and assessed. Smart tutoring systems are a solution to overcome the difficulties of learners by allowing them to have personalized learning and follow-up. This article presents a critique of the effectiveness of these platforms and proposes a generic architecture independent of the learning subject and which offers the learner Machine / Human monitoring.

The objective of this article is to study the views of secondary and high school physics-chemistry teachers regarding the use of PhET(Physics Education Technology) simulations in the teaching and learning of students. A qualitative research method was used in this study. We examined around 78 responses to a survey of physics teachers (38 middle schools and 40 high schools) working in public schools, to give an overview of who uses the PhET simulations, with which student populations, towards which educational objectives and with what scientific approaches. The data collected was analyzed by Statistical Package for the Social Sciences (SPSS) software. The results of this survey reveal, firstly, that most of the teachers questioned use simulations according to the investigation method in teaching physical sciences to achieve the objectives of multiple and flexible learning, secondly they highlight the presence of a set of factors that hinder the use of simulations in the classroom.

Portfolio management is a financial problem that has been the subject of much research over the years. It is a planning task where an agent constantly redistributes resources across a set of assets in order to achieve investment objectives and thereby maximize return. However, it remains difficult to obtain an optimal strategy in an environment as complex and dynamic as the financial market. Our article focuses on solving this stochastic control problem in order to obtain an optimal strategy that would allow us to make profitable decisions by interacting directly with the environment. To do this, we explore the power of deep reinforcement learning which differs from traditional Machine Learning by combining the task of predicting stock behavior and analyzing the optimal course of action in a single unit, thus aligning the problem of Machine Learning with the investor's objectives. As a method, we propose to use the Deep Deterministic Policy Gradient which is an off-policy algorithm and is used for environments with continuous action spaces. The obtained results demonstrate that the model achieves a higher rate of return than the strategy of “Uniform Buy and Hold” stocks and the strategy of “Buy Best Stock in last month”.

This position paper describes the results of our meetings with terminologists aimed at capturing missing functionalities concerning term extraction. These experts lack an online tool to allow them the evaluation, modification and creation of terminologies from corpora in different languages. The result is an open-access online website where terminologists can extract automatically terminologies and can upload terminologies created by third parties. The tool also allows them to polish collaboratively the terminologies. Additionally, this tool provides a quality metrics based on the changes made to the terminology, as well as a way to compare two terminologies for the same corpus but created with different methods. We have tested the tool with terminologies in English and Spanish, with corpora from several domains: bio (covid19), legal and scientific papers. Our preliminary results point out the utility of this tool for terminologists.

In this article, we propose the implementation of innovative solutions in an IMS (Internet Multimedia System) network environment. These solutions are implemented in an Asterisk AS (Application Server) server, which we will initially couple with an IMS network core. The core network used here is Clearwater with an outsourced HSS (Home Subscriber Server) from OpenIMSCore. In a second time, to couple with two IMS network cores (Clearwater). The users of each IMS network must be able to benefit from the same telephone services from the HSS. In a fourth generation context, some of our African countries are asking the telecom operators to interconnect. For this reason, we carried out the interconnection between two IMS networks allowing the users of the two IMS networks to be able to communicate with each other and benefit at the same time from the same telephone services implemented in the SA. The IMS occupies an important place in the 4G network as far as voice management is concerned. In this article, we highlight the importance of developing innovative services for the subscribers of a telecom operator. Today some countries are already starting to deploy even 5G which will offer broadband access to users. Voice is managed by the IMS network in 5G. Today, implementing services in IMS would be an advantage for tomorrow's telecom networks. Operators in African countries need to prepare themselves to take a place in the implementation of innovative services for their subscribers.
在本文中，我们提出了在IMS (Internet多媒体系统)网络环境中实现创新的解决方案。这些解决方案是在Asterisk AS (Application Server)服务器中实现的，我们最初将把它与IMS网络核心耦合在一起。这里使用的核心网络是Clearwater，带有OpenIMSCore外包的HSS (Home Subscriber Server)。第二次，与两个IMS网络核心(Clearwater)耦合。每个IMS网络的用户必须能够从HSS获得相同的电话服务。在第四代的背景下，我们的一些非洲国家要求电信运营商相互连接。因此，我们在两个IMS网络之间进行了互连，使两个IMS网络的用户能够相互通信，并同时受益于SA中实现的相同电话服务。在4G网络中，IMS在语音管理中占有重要地位。在本文中，我们强调了为电信运营商的用户开发创新服务的重要性。今天，一些国家已经开始部署5G，为用户提供宽带接入。在5G环境下，语音由IMS网络管理。今天，在IMS中实现服务将是未来电信网络的一个优势。非洲国家的运营商需要做好准备，在为其用户实施创新服务方面占有一席之地。

Content based image retrieval (CBIR) systems can find similar images to a query image in a large image database. This technique is based on the visual features of the image. In this work we propose a CBIR system based on the three descriptors of the image which are the color, texture and shape features. This study extracts robust features from all dataset images and the query image with the same manner. The image descriptors are extracted from the color histogram, gray level co-occurrence matrix and the Hu moments. Then, a classification technique based on the support vector machine is applied to the features database to create four image classes in the purpose of reducing the query time and limiting the search interval. Meanwhile, the image retrieval is performed based on an efficient meta-heuristic algorithm which is the genetic algorithm. The precision and recall measurements are computed based on the obtained results to validate the efficiency of our CBIR system.

Every day, new scientific documents (textual data) and new domain ontologies are published. It requires putting evolving information systems in order to exploit these massive amounts of textual data and ontologies. Hence, the need for data integration is to collect and combine them so we can provide a unified view, which analyze and visualize them for the different analytical needs of scientific researchers. In this sense, we find the Extract Transform Load (ETL) tool. It is one of the most popular approaches for data integration (DI). However, it does not take into consideration semantic data. This requirement gives birth to the Semantic ETL or ETL based on ontologies, which extends traditional ETL. Mostly known as an issue of interest to most researchers, but the latter found it difficult because of the complexity and the processing of Big Data that are characterized by 5V (Volume, Variety, Velocity, Veracity, Value). Succinctly, this paper attempts to discuss two questions such as: (1) What is the capacity of the existing Semantic ETL to manage Big Data and are they relevant in the present? (2) What is our proposal for a Semantic ETL for Big Data to overcome previous works?

In this paper, we present a hybrid classification approach using a weighted contribution of feature point-based and convolutional neural network (CNN) methods to improve classification and recognition of handwritten Tamil vowels. We explore different feature point methods, including BRISK, ORB, and KAZE, such that we featurize input images with a visual bag-of-words representation before applying standard machine learning classifiers including a multi-layer perceptron. We also consider different CNN configurations for this classification task. We find that since feature point methods and CNNs learn different representations of underlying input images, our hybrid classifier outperforms the individual feature point and CNN classifiers with respect to accuracy, precision, recall, and F1 score.

Recently, most research has focused on energy recovery and storage. One of the materials allowing the recovery of dissipated energy is the piezoelectric material. Piezoelectric (PE) materials are functional materials, which fulfill this role in both directions, transforming electrical energy into mechanical and vice versa. In this paper, we are interested in recovering the vibratory energy, otherwise dissipated via conventional shock absorbers, in suspension systems by using piezoelectric materials and reuse it. We propose a physical model integrating a piezoelectric actuator in the vehicle suspension system. This energy is used for the operation of accessories (windows, mirrors …). The idea is to integrate renewable energy sources to optimize the performance of the vehicle. We proposed a multi-physic model of the system under a software used to this type of modeling (LMS.AMESim). The simulation results of the system and its various sub-systems are presented for studying the piezo-actuator response in order to reduce consumption and increase energy performance in a vehicle.

The monitoring of vital signs is essential in the clinical setting, including temperature, respiratory, and heart rates. Remote monitoring devices, systems, and services are emerging as vital signs monitoring must be performed daily. Different types of sensors can be used to monitor breathing patterns and frequency. However, the respiratory rate remains the least measured vital sign in many scenarios due to the intrusiveness of most of the sensors adopted. This is not the case with Covid-19, which directly infects the respiratory system. In this paper, we present a state of the art on the different applications that monitor temperature, heart rate, and restorative rate, as well as the evaluation of an algorithm that extracts the heart rate from an RGB camera.
