Recognition system

This paper aims to develop an effective method for reduction and decomposition on large matrices with low required computational resources and fast processing times. Our contribution is to design a PCA-SVD hybrid method that dividesthe feature extraction into two phases: PCA-based size reduction and SVD-based decomposition. In our method, PCA is first applied to a large matrix to extract its important components

This thesis attempts to address the problem of how best to remedy different types of channel distortions on speech when that speech is to be used in automatic speaker recognition and verification systems. Automatic speaker recognition is when a person's voice is analysed by a machine and the person's identity is worked out by the comparison of speech features to a known set of speech features. Automatic speaker verification is when a person claims an identity and the machine determines if that claimed identity is correct or whether that person is an impostor.

A high-affinity monoclonal antibody (M27), raised against the human thrombin–antithrombin complex, has been identifiedand characterized. The epitope recognizedbyM27 was located to the linear sequence FIREVP (residues 411– 416), located in the C-terminal cleavage peptide of anti-thrombin.This regionoverlaps, by two residues, theputative binding site of antithrombin for the serpin–enzyme complex receptor.

Molecular mechanics calculations on conformers of Ac-HGly-NHMe, Ac-b 2 -HAla-NHMe and Ac-b 3 -HAla-NHMe indicate that low-energy conformations of the b-amino acids backbone, corresponding to gauche rotamers around the Ca–Cbbond, may overlap canonical backbone conformers observed for a-amino acids. Therefore, Sub-stance P (SP) was used as a model peptide to analyse the structural and biological consequences of the substitution of Phe7andPhe8by(R)-b 2 -HPheandofGly9byHGly (R)-b 2 -HAla or (S)-b 3 -HAla....

Collectins are a family of collagenous calcium-dependent defense lectins in animals. Their polypeptide chains consist of four regions: a cysteine-rich N-terminal domain,a colla-gen-like region,ana-helical coiled-coil neck domain and a C-terminal lectin or carbohydrate-recognition domain. These polypeptide chains form trimers that may assemble into larger oligomers. The best studied family members are the mannan-binding lectin,which is secreted into the blood by the liver,and the surfactant proteins A andD,which are secreted into the pulmonary alveolar and airway lining fluid....

Bacterial lipoproteins⁄peptides are composed of di-O-acylated-S-(2,3-dihyd-roxypropyl)-cysteinyl residues N-terminally coupled to distinct polypep-tides, which can be N-acylated with a third fatty acid. Using a synthetic lipopeptide library we characterized the contribution of the lipid portion to the TLR2 dependent pattern recognition.

Ephrin receptor tyrosine kinase A3 (EphA3, EC 2.7.10.1) is a member of a unique branch of the kinome in which downstream signaling occurs in both ligand- and receptor-expressing cells. Consequently, the ephrins and ephrin receptor tyrosine kinases often mediate processes involving cell–cell con-tact, including cellular adhesion or repulsion, developmental remodeling and neuronal mapping.

The recognition of ubiquitylated substrates is an essential element of ubiqu-itin⁄26S proteasome-mediated proteolysis (UPP), which is mediated directly by the proteasome subunit RPN10 and⁄or RPN13, or indirectly by ubiquitin receptors containing ubiquitin-like and ubiquitin-associated domains. By pull-down and mutagenesis assays, we detected cross-species divergence of the major recognition pathways.

More than half of flowering plants have a sophisticated mechanism for self-pollen rejection, named self-incompatibility. In the Brassicaceae family, the recognition specificity of a self-incompatibility system is achieved by the interaction of the stigmatic S-receptor kinase and its ligand S-locus cys-teine-rich protein, which are encoded by two tightly linked polymorphic genes.
