Application of Nitride based Semiconductors to High-speed Optoelectronics

Bandar Alshehri, Karim Dogheche, El Hadj Dogheche

III-nitrides materials are very promising ternary alloy system that receives a lot of attentions thanks to theirs tunable bandgap that varies from near infrared to near ultraviolet regions. Until now, InGaN/GaN materials have been widely used in various applications like high efficiency solar cells...

My heart is in my hands: The interoceptive nature of the spontaneous sensations felt on the hands

George A. Michael, Janick Naveteur, Marie-Agnes Dupuy, Laurence Jacquot

Somatic sensations may arise in the total absence of external stimuli, i.e., spontaneous sensations (SPSs). Because the background of body sensations has been mentioned as a possible contributor to interoceptive functions, such as the perception of the self and the conscious awareness of one's...

An ontology-based CBR approach for personalized itinerary search systems for sustainable urban freight transport

Amna Bouhana, Amir Zidi, Afef Fekih, Habib Chabchoub, Mourad Abed

This paper presents a novel information retrieval approach for personalized itinerary search in urbanfreight transport systems. The proposed approach is based on the integration of three techniques: CaseBase Reasoning, Choquet integral and ontology. It has the following advanced features: (1) user-...

Stability analysis of a class of uncertain switched systems on time scale using Lyapunov functions

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper deals with the stability analysis of a class of uncertain switched systems on non-uniform time domains. The considered class consists of dynamical systems which commute between an uncertain continuous-time subsystem and an uncertain discrete-time subsystem during a certain period of time...

Error analysis for a mixed DG method for folded Naghdi's shell, Analyse d'erreur pour une méthode de Galerkin discontinue mixte pour une coque de Naghdi pliée

Serge Nicaise, Ismail Merabet

In this Note, we perform some error analyses of a mixed discontinuous formulation for Naghdi's equations for thin linearly elastic shells. Using a combination between the a priori and the a posteriori techniques, we derive a quasi-optimal a priori error estimate and an efficient and reliable a..., Dans cette Note, nous fournissons des estimations d'erreur d'une méthode d'éléments finis discontinus mixte proposée pour résoudre les équations du modèle de Naghdi de coques linéairement élastiques. En utilisant une combinaison entre les techniques de l'analyse a priori et...

Numerical characterization of a γ-Stirling engine considering losses and interaction between functioning parameters

Houda Hachem, Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

In this work a numerical model was developed to optimize a kinematic Gamma Stirling engine. In this model thermal and mechanical losses are included to approximate experimental results. The influences of three operation parameters (filling pressure (3, 5, 10bar), hot end temperature (300, 400, 500°...

Stability of abstract–wave equation with delay and a Kelvin–Voigt damping

Kaïs Ammari, Serge Nicaise, Cristina Pignotti

In this paper we consider a stabilization problem for an abstract wave equation with delay and a Kelvin-Voigt damping. We prove an exponential stability result for appropriate damping coefficients. The proof of the main result is based on a frequency-domain approach.
