Dispersion curves of 2D rods with complex cross-sections: double orthogonal polynomial approach

J.G. Yu, Jean-Etienne Lefebvre, Ch. Zhang, Faniry Emilson Ratolojanahary

Orthogonal polynomial series approach has been used to analyze the guided wave propagation in structures for about 20 years. These structures have always one infinite dimension in the waveguiding direction and, sometimes a regular finite cross-section (axially infinite solid or hollow cylinder for…

The Multidimensional Wave Equation with Generalized Acoustic Boundary Conditions II: Polynomial Stability

Z. Abbas, Serge Nicaise

We study the wave equation on a domain of ℝd, d ≥ 2, with dynamical boundary control applied on a part of the boundary and a Dirichlet boundary condition on the remaining part. We prove the polynomial stability of our model by two different methods: the resolvent and multiplier methods. Some…

Towards Ontology Matching Based System Through Terminological, Structural and Semantic Level

Aroua Essayeh, Mourad Abed

Ontology is a new paradigm introduced with the semantic web to describe in an explicit and formal way the various aspects of knowledge of a specific field. For this purpose, a single ontology may not be comprehensive to represent all due to the lack of a common and shared ontology between…

Observability and Observer Design of Partially Observed Petri Nets

Fayssal Arichi, Petreczky Mihaly, Mohamed Djemai, Brahim Cherki

This paper investigates observability and observer design of partially observed Petri nets (POPN). By using methods for descriptor systems, two major contributions are presented. First, a novel algebraic condition for POPN observability is presented. Second, an asymptotic observer is constructed…

Approximation of the two-dimensional Dirichlet problem by continuous and discrete problems on one-dimensional networks

Maryse Bourlard-Jospin, Serge Nicaise, Juliette Venel

We show that the solution of the two-dimensional Dirichlet problem set in a plane domain is the limit of the solutions of similar problems set on a sequence of one-dimensional networks as their size goes to zero. Roughly speaking this means that a membrane can be seen as the limit of rackets made…

A dispersive estimate for the Schrödinger operator in star-shaped networks

Felix Ali Mehmeti, Kaïs Ammari, Serge Nicaise

We prove the time decay estimates L1(R)→L∞(R), where R is an infinite star-shaped network, for the Schrödinger group eit(−d2dx2+V) for real-valued potentials V satisfying some regularity and decay assumptions. Further we show that the solution for initial conditions with a lower cutoff frequency…

Non-contact ultrasonic non-destructive techniques : state of the art and their use in civil engineering

Mariusz Kaczmarek, Bogdan Piwakowski, Radoslaw Drelich

Ultrasonic methods of testing of civil engineering materials in air where both transmission of waves into materials and reception of signals are contactless are reviewed. Short history, technical details and examples of applications of currently available methods are discussed. Keywords: ultrasound…
