The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages.Alite is the main constituent of Portland Cement (PC), and is responsible ...
Despite being a powerful medical imaging technique which does not emit any ionizing radiation, magnetic resonance imaging (MRI) always had the major problem of long scanning times that can take up to an hour depending on the application. It also requires u ...
Compressed sensing is a new trend in signal processing for efficient sampling and signal acquisition. The idea is that most real-world signals have a sparse representation in an appropriate basis and this can be exploited to capture the sparse signal by ta ...
Bayesian estimation problems involving Gaussian distributions often result in linear estimation techniques. Nevertheless, there are no general statements as to whether the linearity of the Bayesian estimator is restricted to the Gaussian case. The two comm ...
Linear optimal gains Gopt(ω) are computed for the separated boundary-layer flow past a two-dimensional bump in the subcritical regime. Very large values are found, making it possible for small-amplitude noise to be strongly amplified and to destabi ...
This work connects of three domains of fiber optics : the fiber Bragg gratings (FBG), the optical low coherence reflectometry (OLCR) and the fiber optical sensors (using FBGs, the OLCR or a combination of both). Fiber Bragg gratings are fiber optic devices ...
Complex of general formula I in which R1, R2 and R3, which may be identical or different, represent separately a linear or branched alkyl radical of 1 to 5 carbon atoms, or, together with the nitrogen atom to which they are attached, a heterocyclic ...
