Context aware human machine interface for decision support
Humans are often impacted by the presentation of choices in a digital environment. But they differ in their characteristics, behaviours, skills, limitations, and act differently in the same environment. Therefore, Influencing users choices through adaptive human-machine interfaces is crucial in context-aware technologies characterizing the industry 5.0. Our research efforts therefore focus on developing a reference […]

Numerical analysis of repaired wall loss defect pipelines for optimum composite wrap thickness
This paper presents the numerical analysis of failure pressure of wall loss defect metallic pipelines and validate it with experimental results. An optimization study is carried out using developed numerical model to propose the optimum composite repair thickness for cost effective repair system. A nonlinear explicit FE code with constitutive models for metallic steel and […]

Rechargeable Battery State Estimation Based on Adaptive-Rate Processing and Machine Learning
The generalization of the use of electronic systems and their integration in industrial systems and different aspects of modern life (internet of things, electric vehicles, robotics, smart grids), give rise to new challenges related to the storage and optimized management of energy. Lithium-on batteries perfectly meet this objective due to their good qualities such as […]

The NP-completeness of quay crane scheduling problem
This paper discusses the computational complexity of the quay crane scheduling problem (QCSP) in a maritime port. To prove that a problem is NP-complete, there should be no polynomial time algorithm for the exact solution, and only heuristic approaches are used to obtain near-optimal solutions but in reasonable time complexity. To address this, first we […]

Localized buried P‑doped region for E‑mode GaN MISHEMTs
A new design for an enhancement mode Gallium Nitride (GaN)-based High Electron Mobility Transistor (HEMT) is proposed along with a novel fabrication technique. Normally-off operation is achieved through the introduction of a localized P-region below the AlGaN/GaN interface underneath the gate electrode. Since achieving high hole concentration through ion implantation is experimentally challenging, the effect […]

Distance project-based learning during lockdown and learner’s motivation
During the first lockdown due to Covid-19 pandemic, project-based learning (PBL) had to be implemented remotely. To gain knowledge on this learning context, we monitored motivation (in Self-Determination Theory framework), flow, social identification and self-rated performance during a 10-day project conducted with 281 engineering students. Final grades were also collected as objective performance indicators. Results […]

A Survey of Artificial Intelligence Based WSNs Deployment Techniquesand Related Objectives Modeling
Recent advances in hardware and communication technologies have accelerated the deployment of billions of wireless sensors. This transformation has created a wide range of applications adapted to the evolving trends of our daily life requirements. Wireless sensor networks (WSNs) could be deployed in several target areas including buildings, forests, oceans, and smart cities. Nevertheless, finding […]

Guide pratique de la pédagogie de l’alternance
Ces itérations peuvent prendre différences formes. Elles peuvent être potentialisées par une pédagogie qui permet, grâce aux pratiques pédagogiques mobilisées, 1 de se positionner sur l’apprentissage d’un métier (employabilité), 2 qui cherche à réduire les écarts entre la pratique et la théorie (réflexivité), 3 s’appuie sur l’expérience de formation (individualisation), 4 construit des parcours soutenants […]

GUEZ_Système d’instruments et environnement capacitant
Cet article s’intéresse au cours à distance en temps de pandémie. Nous proposons une analyse de dix entretiens d’explicitation avec des enseignants qui exercent dans l’enseignement supérieur pour répondre à deux objectifs : 1) identifier les instruments privilégiés et leurs usages pour assurer une continuité pédagogique à distance ; 2) distinguer les freins et leviers […]

Collaborative Mobile Robotics for Semantic Mapping A Survey
Ensuring safety in human–robot collaboration is one of the main challenges in mobile robotics today. Semantic maps are a potential solution because they provide semantic knowledge in addition to the geometric representation of the environment. They allow robots to perform their basic tasks using geometric representation, mainly localization, path planning and navigation, and additionally allow […]

Building Occupancy Detection using Machine Learning-based Approaches: Evaluation and Comparison
Building occupants and systems have huge impact on total energy use of the building due to their interaction with the building envelope and systems. The human factor and their behavior play a significant role in this process, and their influence must be considered. As a result, occupant behavior analysis and their detection, estimation, and prediction […]

View Selection for Industrial Object Recognition
The last industrial revolutions and the digital transformation have led to a rise of robotics and to the emergence of the concept of digital twin. A major challenge falls within the update of this virtual representation, so that the supervision operator and the system itself can take appropriate decisions. One way to achieve that is […]
