Hamlet's Ghost on Screen : The paradox of the Seventh Art
The infinite possibilities offered by the cinema in terms of special effects, fully exploited since Méliès, should have enabled directors to show infinite... -
Continuity of representations of topological groups
Let L(X) be the algebra of all bounded operators on a Banach space X, and let t:G⇾L(X) be a representation of a topological group G in X. For every element g in the... -
Functional problems approximation : pseudospectrum of a differential operator...
Using functional and numerical methods, we localize the spectrum of a differential operator and we build approximate solutions for classes of Fredholm equations of the... -
Statistical description of the sea surface and colocalised microwave measurem...
More and more micro-wave data are available from spatial and airborne measurements over sea surface. An accurate backscattering model which is capable of taking the... -
The SNIFS integral field spectrograph : Simulation and results analysis.
By observing the low redshit type Ia supernovae, the mission of the SNIFS instrument is to help us to have a better knowledge and understanding of those objects. The... -

Two-dimensional FEM analysis of Brillouin gain spectra in acoustic guiding an...
The analysis of optical and acoustic properties of optical fibers is required for accurate Brillouin gain spectrum (BGS) determination. We present a full... -
Importance of residual stresses in the brillouin gain spectrum of single mode...
Residual stresses inside optical fibers can impact significantly on Brillouin gain spectrum. Based on a 2D-FEM modeling, theoretical results are compared with... -
In situ radiation influence on strain measurement performed by Brillouin sensors
A new approach is proposed to monitor in situ gamma radiation influence on Brillouin optical fiber extensometers. Experimental results are illustrated with two fiber... -

Development of an ultrasonic instrumentation for fluid velocity measurement b...
Doppler velocimetry by pulsed ultrasounds makes it possible to obtain the velocity profile of a fluid flow. The mean velocity estimation is carried out, for each... -
Contribution to the study of discrete Schrödinger operators
The domain of this thesis is included in the general theory of discrete one dimensional random operators. In Chapter 1, we provide interesting elements of the... -
Traffic noise spectrum analysis: dynamic modeling vs. experimental observations
This paper compares two traffic representations for the assessment of urban noise frequency spectrum: (i) a static one, based on mean vehicle speeds and flow rates,...
