Design and experimental analysis of a high force piezoelectric linear motor

Sofiane Ghenna, Yves Bernard, Laurent Daniel

In this paper, the design and experimental analysis of a piezo-motor for applications requiring compact size, high blocking and driving forces are presented. Mechanical design addresses difficulties associated with high integration flexibility and high blocking force for the motor. The technology…

Multifractal analysis for improved osteoporosis classification

Ouardia Bouzeboudja, Boualem Haddad, Abdelmalik Taleb-Ahmed, Soltane Ameur, Mohammed El Hassouni, Rachid Jennane

Osteoporosis is characterized by decrease of bone mineral density and alterations of the bone microarchitecture, leading to bone fragility and an increased risk of fractures. Discrimination between osteoporotic and healthy subjects using X-ray images presents a major challenge for medical image…

Visual soft landing of an autonomous quadrotor on a moving pad using a combined fuzzy velocity control with model predictive control

Oussama Bouaiss, Raihane Mechgoug, Abdelmalik Taleb-Ahmed

Autonomous landing is a vital option for Unmanned Aerial vehicles (UAV), as it can be a fail-safe in many critical cases. This paper demonstrates a complete solution for the soft landing application of a fully autonomous quadrotor on a moving pad considering external disturbance, model…

Bound states in the continuum in circular clusters of scatterers

Marc Martí-Sabaté, Bahram Djafari-Rouhani, Daniel Torrent

ABSTRACTIn this work we study the localization of flexural waves in highly symmetric clusters of scatterers. It is shown that when the scatterers are placed regularly in the perimeter of a circumference, the quality factor of the resonances strongly increases with the number of scatterers in the…

Modeling and control of conducting polymer actuator

Lingxiao Xun, Gang Zheng, Sofiane Ghenna, Alexandre Kruszewski, Eric Cattan, Christian Duriez, Sebastien Grondel

Conducting polymer (CP) actuator has nonlinear dynamic characteristics during its charge process. In this study, we proposed an electromechanic model and an optimal controller for a type of ionic electroactive polymer (IEPA) actuator with submillimeter scale, which can produce large deformation…

Fabrication of a novel electrochemical biosensor based on a molecular imprinted polymer-aptamer hybrid receptor for lysozyme determination

Tavoos Beiki, Ghasem Najafpour-Darzi, Maedeh Mohammadi, Mohsen Shakeri, Rabah Boukherroub

In this work, a novel, sensitive, and rapid electrochemical biosensor was employed to detect lysozyme (Lys) using a double receptor of molecular imprinted polymer (MIP)-aptamer. First, a glassy carbon electrode (GCE) was modified with a nanocomposite consisting of multi-wall carbon nanotubes (…

Three-in-one ITO-Cu-ITO based backplane circuit strategy for micro-LED display

Jingxuan Pei, Zhiqiang Zhang, Xiang Yu, Lei Yang, Jing Zhang, Rabah Boukherroub, Yayun Liu

A three-in-one ITO-Cu-ITO multilayer wire strategy is developed to reliably fabricate large-size backplane circuit for micro-LED display. The multilayered wire was prepared by magnetron sputtering and electroplating, and presented a sandwich structure of ITOtransitional layer /Cuseed layer /…

Functionalized reduced graphene oxide as a useful and efficient base catalyst for the preparation of 4 H‐pyran and pyran‐like tacrine compounds and their antibacterial activity

Maryam Mirza-Aghayan, Marzieh Mohammadi, Rabah Boukherroub, Katayoon Ravanavard

An easy, effective and eco-friendly one-pot process for the preparation of 4H-pyran compounds has been established by using a catalytic amount of reduced graphene oxide functionalized with diethylenetriamine (rGO-DETA) in water under mild conditions. The functionalized catalyst was very effective…

Over the past decade, we have seen that a large and growing number of people usetheir own vehicles as their main mode of transportation. This situation has an impact on traffic conditions that are increasingly unpredictable. Traffic jams and accidents are increasing from year to year. To try to…, Durant cette dernière décennie, on constate qu’un nombre important et de plus en plus croissant de personnes utilisent leur véhicule personnel comme mode de transport principal. Cette situation a un impact sur les conditions de circulation qui sont de plus en plus imprévisibles, les embouteillages…
