Cuer, Michel ; Duffet, Carole ; Ivorra, Benjamin ; Mohammadi, Bijan | 2005Reflection tomography allows the determination of a velocity model that fits the traveltime data associated with reflections of seismic waves in the subsurface. The resulting nonlinear optimization problem is solved classically by a Gauss-Newton[...]![]()

In this paper we reformulate global optimization problems in terms of boundary value problems (BVP). This allows us to introduce a new class of optimization algorithms. Indeed, current optimization methods, including non-deterministic ones, can [...]![]()

Ivorra, Benjamin ; Mohammadi, Bijan ; Redont, Patrick ; Dumas, Laurent ; Durand, Olivier | Inderscience | 2006A new global optimization algorithm is presented and applied to the design of high-channel-count multichannel filters based on sampled Fiber Bragg Gratings. We focus on the realization of particular designs corresponding to multichannel filters [...]![]()

Isebe, Damien ; Azerad, Pascal ; Bouchette, Frederic ; Ivorra, Benjamin ; Mohammadi, Bijan | John Wiley & Sons Ltd. | 2008-05-21This paper describes how to tackle new challenging coastal engineering problems related to beach erosion with a shape optimization approach. The method modifies the shape of the sea bottom in order to reduce beach erosion effects. Global optimiz[...]![]()

Debiane, L. ; Ivorra, Benjamin ; Mohammadi, Bijan ; Nicoud, F. ; Ern, A. ; Poinsot, T ; Pitsch, H. | 2004-07We apply control theory for PDEs to flame control. The targeted flame is calculated with complex chemistry. For pollutant control in flames we study both the control of temperature distribution in the flame and flame length at given fuel rate in[...]
