Public clouds enable storing and sharing data with efficient cost and high availability. Nevertheless the benefits, cloud providers are recurrently breached by malicious users exposing sensitive user content. To mitigate the lack of security guarantees, users can impose...

In this thesis we are interested to the study of spectral accumulation phenomena of some opeators coming from quantum physics, namely Schrödinger, Paul and Dirac operators. Typically, these operators appear in the modeling of some physical problems in the form of evolut...

In this manuscript, we present a shape optimization method based on CAD parameters such as lengths, angles, etc. We rely on gradient-based optimization techniques. The sensitivity of the objective function, with respect to the mesh nodes position, is provided by an adjo...

Vegetable oils like camelina and sunflower oils are sources of healthy polyunsaturated fatty acids that are however highly susceptible to oxidative degradation. This work aimed at enhancing the oxidative stability of edible oils, mostly camelina oil by incorporating phe...

Despite their remarkable success, the first widely spread versions of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 Wireless Local Area Network (WLAN) standard, IEEE 802. 11 a/b/g, featured low spectral efficiencies that are becoming insufficient t...

IgA nephropathy is the most frequent glomerulonephritis worldwide. It features mesangial immunoglobulin (Ig)A deposits and proteinuria, hematuria and glomerular histological lesions. In 25% patients, it evolves, within 20 years, towards the end stage renal disease. Micr...

Hyperstreams are collections of streams with references. The hope is that structured data on a hyperstream can be monitored with lower latency than when communicated on a stream, since data on hyperstreams may be received in parallel rather than in a purely sequential m...

The human genome consists mainly of DNA, a macromolecule consisting of a long linear sequence of bases, tightly packed to fit in the relatively small nucleus. The packing gives rise to multiple hierarchical organizational levels. Recent research has shown that, along wi...

This thesis is devoted to the unmixing issue in hyperspectral images, especiallyin presence of small sized objects. Hyperspectral images contains an importantamount of both spectral and spatial information. Each pixel of the image canbe assimilated to the reflection spe...

Let k be an algebraically closed field with char(k) = 0 and let be polynomials F1,..., Fn such that k[X1,...,Xn]/ is a complete intersection k-algebra. The Bezoutian of F1,..., Fn gives a dualizing form acting on k[X1,...,Xn]/ called Kronecker symbol. It is an algebraic...
