Extraction en phase solide (SPE) : théorie et applications

Solid-Phase Extraction (SPE): Principles and Applications in Food Samples.

Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large amount of solvent, extended operation time/procedure steps, potential sources of error, and high ...

Problème de décidabilité et d'effectivité en théorie de complexité

Ondelettes et applications en imagerie et en calcul de surfaces

This thesis is a theorical and numerical contribution to wavelet transform in image processing and surface computing. Group theory approach, multiresolution approach and lters banc approach of wavelets basis are reviewed. The wavelet transform applications concern image compression, discrete curve representation and surface approximation by radial functions. We begin by reviewing di erent image...

Approximate String Matching: Theory and Applications (La Recherche Approchée de Motifs : Théorie et Applications)

The approximate string matching is a fundamental and recurrent problem that arises in most computer science fields. This problem can be defined as follows : Let D = {x1, x2, . . . xd} be a set of d words defined on an alphabet Σ, let q be a query defined also on Σ, and let k be a positive integer. We want to build a data structure on D capable of answering the following query : find all words i...
