Design of a Low Cost 3D Printable Single-Component Compliant Mechanism for FWMAV’s Wing Actuation
2021
Considering a modern approach to design, one of the viable options for developing innovative projects is the possibility of integrating the effectiveness of the solutions offered by nature and living beings with the latest design methods. With this in mind, the following research exploits the idea of reproducing the natural flexibility inherent in biological structures by combining the advantages of compliant mechanisms with the adaptability of additive manufacturing processes. In the specific, the authors intend to highlight the potential and critical aspects of a possible approach for the application of compliant mechanisms in the development of single-component structures suitable for th…
A Small Scale Resonant Coupling Wireless Power Transmission Prototype for EV Applications
2012
In this paper a low cost prototype of wireless power transfer system based on resonant coupling is presented. The system here proposed can be useful for electric vehicle (EV) battery charging systems: as a matter of fact, it consists mainly of two copper wire coils or windings, placed one in front of the other on the same axis. The inductor coil can easily be placed under the road surface (in a parking), while the other (the receiver coil) in the lower side of the vehicle. By exploiting the coils resonance coupling effect, electric energy can be transferred from the inductor coil to the receiver in order to charge the batteries. Low cost experimental tests carried out at DIEETCAM – Universi…
New Optimization and Security Approaches to Enhance the Smart Grid Performance and Reliability
2016
International audience; Nowadays, the Smart Grid (SG) is becoming smarter thanks to the integration of different information and communication technologies to enhance the reliability and efficiency of the power grid. However, several issues should be met to ensure high SG performance. Among these issues, we cite the problem of electric vehicles (EVs) integration into the SG to avoid electricity intermittence due to the important load that EVs can create. Another issue is the SG communication network security that can be attempted by malicious intruders in order to create damages and make the power grid instable. In this context, we propose at a first level a Bayesian game-theory model that …
Federated Learning for Zero-Day Attack Detection in 5G and Beyond V2X Networks
2023
Deploying Connected and Automated Vehicles (CAVs) on top of 5G and Beyond networks (5GB) makes them vulnerable to increasing vectors of security and privacy attacks. In this context, a wide range of advanced machine/deep learning-based solutions have been designed to accurately detect security attacks. Specifically, supervised learning techniques have been widely applied to train attack detection models. However, the main limitation of such solutions is their inability to detect attacks different from those seen during the training phase, or new attacks, also called zero-day attacks. Moreover, training the detection model requires significant data collection and labeling, which increases th…
Sub-optimal waypoints, UAV path planning and mosaicing application
2016
International audience; Create a complete system of video surveillance using camera mounted on a robot like UAV to maintain optimized vast area coverage and reconstruct an image by using mosaicing techniques. This paper demonstrated the efficiency of using one UAV to cover vast area using optimized positions.
Allocation des ressources dans l’informatique en brouillard le calcul du brouillard véhiculaire pour une utilisation optimale des véhicules électriqu…
2019
Abstract: Technological advancements made it possible for Electric vehicles (EVs) to have onboard computation, communication, storage, and sensing capabilities. Nevertheless, most of the time these EVs spend their time in parking lots, which makes onboard devices cruelly underutilized. Thus, a better management and pooling these underutilized resources together would be strongly recommended. The new aggregated resources would be useful for traffic safety applications, comfort related applications or can be used as a distributed data center. Moreover, parked vehicles might also be used as a service delivery platform to serve users. Therefore, the use of aggregated abundant resources for the …
A multi-agent based cooperative control model applied to the management of vehicles-trains
2017
The use of individual vehicles is becoming more and more important in inner cities, leading to many side problems such as traffic jam, air pollution and accidents. Intelligent vehicles have been studied so as to overcome these problems. Some solutions provided by these works are already available to the general public market such as city safety systems, lane assists,... Many research works are focusing on finding suitable and acceptable solutions to these problems and dealing with traffic jam management. The proposal can tackle the traffic jam problem whether on system level or on individual vehicle providing better control and perception systems aimed at reducing time response and/or at in…
Do you like driving? A critical view on car advertising and its environmental rhetoric
2018
Sustainable development, as well as other narratives within the framework of environmental conservation, is often used as an advertising resource to improve a brand image. In this paper, a teaching proposal based on a critical analysis of the discourse of a set of television commercials is presented. Specific attention is given to the car industry, due to its huge environmental implications and its impact in mass media and popular culture. This study highlights that persuasive discourses around automobile still persist, which are more emotional than rational, as a way to elude the true debates about today's social and environmental challenges. El desarrollo sostenible, así como algunos otro…
Connected vehicles : can V2V communication and internet connectivity improve safety?
2016
This study explores the possibilities of V2V communication on vehicles. Starting with a broad overview of the history of vehicle safety, leading up to current safety technologies and then adding digitalization. Many parts of the everyday life became digital in recent years and the most used transportation device–the car–is to some extend already part of it. The latest studies on the subject will be examined and how the car manufacturers picture the near future of cars that are connected. The possibilities are nearly endless; a car could be aware of an upcoming obstacle, also infrastructure such as traffic lights could send information to approaching cars. In addition, the regular Internet c…
