Abstract:

This thesis lays out the development, analysis, integration and testing of a camber morphing concept for control surfaces dealing with fluidic dynamics, with specific focus on replacing the outboard aileron of fixed-wing aircraft in an effort to increase associated fuel efficiency. Core to the development of the morphing concept was a zero Poisson's ratio (O-v) honeycomb. The state-of-the-art was studied, modified for compatibility with the application intended, was subjected to topological optimization to improve relevant performance charactelistics, and was validated through experimental studies. Mass was reduced by 20% and energy for morphing by 42-55% without affecting load-carrying capability; but fatigue life was reduced by 18%. A near-term performance study was conducted. The outboard aileron of a state-of-the-art A320 wing was replaced with the morphing equivalent, demonstrating higher efficiency and increasing aircraft range by 0.8-0.9% depending on weather conditions in a medium fidelity flight simulation (Heathrow to Amsterdam). A first-iteration long-term study, unrestricted by current design constraints, indicated a significant increase in aerodynamic efficiency; towards 50% for high control surface deflections. Coupled to a pre-stressed hyper-elastic surface skin and an an-ay of micro-linear actuators for morphing, the O-u honeycomb was integrated into a 1.05m span wing for wind-tunnel testing. The generated morphed shapes successfully met the overarching geometric objectives; significant reduction in chordwise and spanwise geometric discontinuities and pressure gradients. Comparison between FE and hammer-testing showed modal frequencies agreed with an average en-or of 8%. Comparison between CFD and wind-tunnel studies showed CL agreement with an average error of 0.07 CL. A methodology for whole wing conformal shape optimisation, based on modified Class Shape Transformations and Bemstein Polynomials, enabled by integration of the O-u honeycomb structure generated coupled to cellular micro-linear actuators, was developed and proposed as a logical step forward to explore the full potential of the morphing system proposed.

When fluctuations in the speed of rotation of the drive pulley are transmitted to the driven pulley via the metal V-belt, the transmitted fluctuations become attenuated as friction force approaches a state of saturation. The research discussed in this paper focused on these fluctuations in the speed of rotation and developed an index for the slip state between the belt and the pulleys.

Abstract:

Les anticorps monoclonaux (mAb) sont d’importants agents thérapeutiques largement utilisés dans le traitement de cancers. Ces protéines recombinantes complexes sont généralement produites dans des lignées cellulaires de mammifères et l’industrie pharmaceutique a développé des procédés robustes permettant d’obtenir de grandes quantités d’anticorps monoclonaux de qualité constante. Une tendance générale observée aujourd’hui est d’éviter l’utilisation de produits d’origine animale dans ces procédés. En effet, ces composés représentent un risque de contamination du médicament par des agents infectieux et les autorités règlementaires renforcent leurs exigences pour leur retrait des procédés de fabrication. Ces composés sont par ailleurs mal définis et posent des problèmes de variabilité des procédés de production. L’objectif de ce projet était de développer un milieu sans dérivés animaux pour la culture d’une lignée cellulaire Sp2/0 utilisée par la société Merck Serono pour exprimer un anticorps monoclonal thérapeutique. Le procédé de fabrication actuel contient de la sérum albumine bovine (BSA) et de l’EX-CYTE (concentré commercial de lipoprotéines et acides gras) extraits de sérum bovin. Le retrait des deux composés du milieu de culture a entrainé une diminution de la productivité du procédé de 87% et il a été observé que l’EX-CYTE et la BSA étaient essentiels pour la survie de notre lignée cellulaire Sp2/0. La BSA a permis à elle seule de remplacer l’EX-CYTE dans le procédé et a été utilisée comme modèle pour le développement d’un remplacement sans dérivés animaux. Une étude de caractérisation de la préparation de BSA a été effectuée afin d’identifier les facteurs responsables de son activité promotrice pour la croissance cellulaire. Les lipides représentaient une partie importante de cette activité mais un rôle significatif d’autres protéines contaminantes a été révélé. Enfin, un supplément lipidique sans dérivés animaux a été développé. Ce supplément était constitué d’un mélange de quatre acides gras (les acides oléique, linoléique, palmitique et stéarique) couplés à de la sérum albumine humaine recombinante (rHSA). Le supplément acides gras-rHSA a permis de remplacer l’EX-CYTE et la BSA et un milieu sans composés d’origine animale a finalement été obtenu
Monoclonal antibodies (mAbs) are important therapeutics widely used for cancer therapy. Mammalian cell lines are usually employed to produce these complex recombinant proteins and the pharmaceutical industry has developed robust processes that deliver large quantities of mAbs with a sustained quality. A general trend observed today is to avoid the use of animal-derived components in such processes. Indeed, these compounds represent a potential risk of contamination of the final drug product with infectious agents and regulatory authorities are putting pressure for their removal from manufacturing processes. Such compounds are also ill defined and source of variability for the production processes. The goal of this project was to develop an animal-derived component free (ADCF) medium for the culture of an Sp2/0 cell line used by the company Merck Serono to express a therapeutic mAb. The manufacturing process currently used contains bovine serum albumin (BSA) and EX-CYTE (a commercial concentrate of lipoproteins and fatty acids) sourced from bovine serum. The removal of both components from the cell culture medium decreased the productivity of the process by 87%. EX-CYTE and BSA were found to be essential for the survival of our Sp2/0 cell line. BSA, which was found to replace EX-CYTE in the process, was used as a model for the development of an animal-derived component free replacement. A characterization of the BSA preparation was carried out to identify the factors responsible for its growth-promoting activity. Lipids accounted for a major part of the activity of the BSA preparation but a significant role of other protein contaminants was revealed. Finally, an animal-derived component free lipid supplement was developed. This supplement consisted in a mixture of four fatty acids (FA) (oleic, linoleic, palmitic and stearic acids) complexed with recombinant human serum albumin (rHSA). The FA/rHSA supplement could substitute for EX-CYTE and BSA and an ADCF medium was finally obtained

Abstract:

Dans le but de trouver de nouveaux catalyseurs d’oxydation du butane en anhydride maléique, de nouvelles phases appartenant au système V. P. Mo. 0 ont été synthétisées et caractérisées par différentes méthodes d’'analyse physico-chimiques (diffraction X ; spectroscopies IR, UV, RPE ; microscopie électronique ; analyses thermiques différentielles et gravimétriques). Le montage d’un test catalytique (réacteur intégra à lit fixe, analyse chromatographique en ligne des effluents) a permis de déterminer l’activité et la sélectivité de ces phases. Pour corréler les propriétés catalytiques et physico-chimiques, il a été nécessaire également d’examiner à la fois les propriétés électroniques (conductivité électrique, résonance paramagnétique électronique) et la mobilité de l'oxygène à l'intérieur du réseau cristallin de ces phases (analyses thermiques). Les différences et les analogies existant entre les propriétés structurales, thermodynamiques, cinétiques et catalytiques des systèmes V. P. O et V. P. Mo. 0 ont permis ainsi de mieux comprendre les mécanismes réactionnels et les réactions solide-solide et solide-gaz intervenant avec ces systèmes. L'ensemble de ces résultats contribue à l'amélioration des procédés de fabrication de l'anhydride maléique partir du butane.

O uso da Metodologia Seis Sigma nas organizações tornou-se economicamente viável para a maioria das empresas que buscam sustentabilidade, lucratividade e dominância no mercado competitivo. A maior parte das empresas que possuem a metodologia difundida e implementada, estão mais preocupadas com relação ao processo de seleção e priorização de projetos no Gerenciamento de Portfólios de Projetos Seis Sigma. O Processo de Seleção e Priorização de Projetos Seis Sigma é considerado uma parte crítica no Processo de Gerenciamento de Portfólios de Projetos, que de certa forma, influencia positivamente ou negativamente na estratégica da organização. A Seleção e Priorização de projetos, para a maioria das empresas, são realizadas por meio de julgamento subjetivo do decisor ou empregada de certas ferramentas que não garantem a integridade na escolha de potenciais projetos para compor a carteira de investimentos. Diante do cenário observado foi proposto um framework detalhado do Processo de Seleção e Priorização de Projetos Seis Sigma, abrangendo o PROMETHEE V, um modelo híbrido de Decisão Multicritério e Programação Combinatória Discreta. O uso do Método PROMETHEE II favoreceu uma pré – ordem completa dos projetos de forma decrescente, a partir de então, foi empregado o uso do Problema da Mochila 0 – 1, para maximizar os projetos que tenham maiores scores em certas condições de investimento e disponibilidade de recursos. Os projetos identificados são os que irão fazer parte da carteira de investimentos. A partir dos resultados obtidos na aplicação do modelo no ambiente empresarial, foi constado que o mesmo satisfaz as condições e necessidades da empresa que pretende obter o Processo de Seleção e Priorização de Projetos Seis Sigma eficiente.

Le deuxième point majeur de cette étude concerne les capteurs élémentaires dont le choix a été fortement influencé par l'application finale du système : la radiogoniométrie sur porteur mobile. Ces antennes ont ensuite été associées en réseau de manière à obtenir une couverture radioélectrique omnidirectionnelle.

Abstract:

L'effet photorefractif consiste en un changement local de l'indice de refraction sous une illumination non uniforme, dans certains cristaux photoconducteurs et electrooptiques. Notre objectif etait de contribuer a le comprendre d'un point de vue microscopique par l'identification des niveaux presents dans la bande interdite et des mecanismes de transfert de charge associes, et alors d'etablir le lien avec l'approche macroscopique de cet effet. Les methodes de caracterisation que nous avons utilisees sont l'absorption, le dichroisme circulaire magnetique (dcm), et la detection optique de la resonance paramagnetique. A partir de l'examen de plusieurs echantillons cd 1 xzn xte:v, nous avons identifie les ions v 2 + et v 3 + en site cd. Par l'etude des effets d'eclairements secondaires, nous avons observe la photoneutralisation de v 3 + a 1. 55 micron et la photoionisation de v 2 + a 1. 06 micron. Le niveau donneur v 2 + / 3 + a ete localise a 0. 9 ev en dessous de la bande de conduction. Il a ete montre que c'est le principal niveau implique dans l'effet photorefractif. Grace au photo-dcm, nous avons determine pour la premiere fois le rapport des concentrations de v 2 + et v 3 + dans les echantillons. Cette technique originale combinee a la resonance paramagnetique, nous a permis de doser leurs quantites. Dans le cas de bi 1 2mo 2 0:al (m = ge, si), l'illumination dans l'ultraviolet induit une bande d'absorption tres large et complexe vers 1. 5 micron. Son analyse montre des processus du type : al mo 4 0 + e v al mo 4. L'aluminium s'insere en site tetraedrique de m et peut exister sous deux formes : al mo 4 decrit al 3 + et al mo 4 0 decrit al 3 + habille d'un trou plus ou moins delocalise sur les atomes d'oxygene. Dans le domaine visible et proche infrarouge, le dcm est interprete selon un modele d'orbitales moleculaires. Nous suggerons enfin que bi 1 2mo 2 0:al pourrait presenter un gain photorefractif interessant a 1. 55 micron, sous un eclairement secondaire ultraviolet.

Ce travail de thèse est consacré à l’étude de la cristallochimie particulière des matériaux cristallisés à base d’oxyde de tellure VI (tellurates), candidats potentiels dans les technologies LTCC. L’estimation de la susceptibilité d’optique non linéaire d’ordre 3, des phases cristallisées du système TeO2-TeO3, par calculs ab initio, a montré des résultats prometteurs ouvrant des perspectives intéressantes pour l’élaboration de verres à base d’oxyde de tellure VI. Le composé TeO3-β est le plus simple des matériaux à base d’oxyde de tellure VI. L’étude vibrationnelle de sa structure spécifique met en évidence une structure de type tridimensionnelle semblable à la famille des pérovskites cubiques et très différentes du composé élémentaire à base d’oxyde de tellure IV, TeO2-a, de structure de type ilot. Cette étude a servi de base à l’analyse vibrationnelle de composés tellurates complexes

The estimation of the 3rd order nonlinear optical susceptibility, by ab initio calculations, of the crystalline phases of the system TeO2-TeO3 showed promising results openning interesting perspectives for the development of tellurium VI oxide based glasses. The TeO3-βcompound is the simplest tellurium oxide VI based material. The vibrational study of its specific structure reveals a three-dimensional type structure similar to the cubic perovskite family and very different to the elemental tellurium oxide IV TeO2-a, island type structure. This study was the basis for the vibrational analysis of complex tellurate compounds

Rotational energy transfer (RET) among the SH (A2Σ+, v′=0) and (X2Π, v〃=0) ro-vibrational levels by collisions with Ar has been studied in both theoretical and experimental manners. The SH (A2Σ+) state is probed using a laser-induced dispersed fluorescence technique, following photodissociation of H2S at 248 nm. The Ar pressure is adjusted appropriately to allow for significant observation of RET process in single collision condition. The spin-resolved rate constants are then evaluated with the aid of a kinetic model: Firstly, a set of rate constants is determined from experimental data by assuming single collision approximation. Then such initial guess values are substituted into rate equation and an iterative process is performed in order to obtain converged rate constants which incorporated the multi collision effect. The theoretical counterparts of both SH (A2Σ+ v′=0) and (X2Π v〃=0) can be calculated by using quantum scattering method with newly fitted potential energy functions based on ab initio potential energy surfaces. Although the Λ doublet resolved rate constants of SH (X2Π, v〃=0) are merely determined via theoretical calculation, experimental time resolved rotational populations are measured via laser induced fluorescence (LIF) technique and compared with simulation in order to examine the reliability of theoretical data. For the SH (A2Σ+ v=0) case, the experimental and theoretical kinetic results are essentially consistent in the trend of N (spinless angular momentum quantum number) and ΔN dependence. The principle of microscopic reversibility is also examined for both experimental and theoretical kinetic data, showing that translational energies of the RET collisions are close to thermal equilibrium at room temperature. Fine structure conserving propensity is found in the fine structure resolved rate constants. Such propensity can be rationalized according to angular momentum vector model. For the SH (X2Π, v〃=0) results, RET rate constants of Λ doublet levels are determined theoretically. In order to examine the reliability of theoretical data, experimental time resolved SH (X2Π, v〃=0) rotational populations are measured via LIF technique and compared with theoretical simulation. Several propensity rules are found in the Λ resolved rate constants, either favor the final level with certain reflection symmetry or tend to conserve the parity. Explanations are given for these propensity rules, basing on both the high collision energy limit and the interference effect in interaction potentials.

Abstract:

In the Czech Republic, about one per cent of children grow up outside their own families, mainly children under the age of three. For this reason the Czech Republic has lately received several important challenges concerning a fundamental reform of the children at risk care system. The aim of my thesis was to carry out an analysis of the development and changes in the comprehensive care and in the situation of the children in the Children?s Centre Jihlava and in the Children?s Home Kamenice nad Lipou in the years 2005, 2010 and 2011 in chosen aspects. The research was focused on changes over time in the situation of concrete children?s homes, further on the changes in the provided care depending on the children?s characteristics and specific needs, and finally on the changes in the cooperation with the biological families and in the circumstances how the stay of children is terminated. To achieve these goals of my thesis, a secondary data analysis and SWOT analysis was carried out. Two files were analysed recording the situation in the Children?s Centre and in the Children?s Home during the the years 2005, 2010 and 2011.

We report the results of a study of the exclusive charmless semileptonic decays, B^+--> êta^(') l^+v and B^0--> pi^- l^+v, undertaken with approximately 464 million BBbar pairs collected at the Upsilon(4S) resonance with the BABAR detector. The analysis uses events in which the signal B decays are reconstructed with a loose neutrino reconstruction technique. We obtain partial branching fractions for B^+--> êta l^+v and B^0--> pi^- l^+v decays in three and twelve bins of q^2, respectively, from which we extract the f_+(q^2) form-factor shapes and the total branching fractions B(B^+--> êta l^+v) = (3.39 +/- 0.46_stat +/- 0.47_syst) x 10^-5 and B(B^0--> pi^- l^+v) = (1.42 +/- 0.05_stat +/- 0.08_syst) x 10^-4. We also measure B(B^+--> êta' l^+v+) = (2.43 +/-0.80_stat +/- 0.34_syst) x 10^-5. We obtain values for the magnitude of the CKM matrix element |V_ub| using three different QCD calculations.

Abstract:

This thesis is concerned with the level of parents´ awareness and attitudes to above-standard vaccination of children from 0-3 years in Příbram. Among the optional vaccination of children from 0-3 years belong vaccination against pneumococcal disease, rotavirus infections, meningococcal invasive disease (caused by meningococcal of group C, A+C, or A, C, W 135 and Y, now also of group B), tick-borne encephalitis, varicella smallpox, influenza and hepatitis A (or a combination of type A + B). The first part deals with the issue in a theoretical perspective. It foreshadows the basic characteristics of the diseases against which the premium vaccination of children from 0-3 years is offered. Further it is focused on vaccines against these diseases, which can occur in the Czech Republic. The survey is summarized in the research. There were parents of children attending one of the 12 kindergartens in Příbram in the sample of the research. tely 40% of the parents (or mothers) of these children in each kindergarten.The results were summarized in schedules of absolute and relative frequencies, or graphs. It was set three basic goals that were met with five hypotheses. The first of these was to monitor the attitudes of parents to above-standard vaccination of children from 0-3 years in Příbram. To this target relate hypothesis H1: Parents are interested in above-standard vaccination of children from 0-3 years in Příbram, H2: Parents with higher educational level have significantly higher interest in above-standard vaccination of children from 0-3 years and H3: Parents are statistically significantly more interested in vaccination against tick-borne encephalitis than other extra vaccination of children from 0-3 years, due to an endemic area of tick-borne encephalitis in Příbram. These hypotheses were not confirmed statistically. The second aim investigated the main reason for the possible lack of interest in extra vaccination of children from 0-3 years in Příbram. The target was filled with hypothesis H4: The main reason for the possible lack of parents´ interest in extra vaccination of children from 0-3 years is high price of vaccines, which was statistically refuted. The third goal was to explore parents' knowledge about diseases against which the extra vaccination of children from 0-3 years is offered. To this goal was set the hypothesis H5: Parents have sufficient information about the diseases against which the extra vaccination of children from 0-3 years is offered. This hypothesis was confirmed. The hypotheses were verified by ?chi-square? test at a significance level of 5%, which is an instrument of verification or falsification of hypotheses. This work may be used in practice as a preview to the parents´ awareness and interest in extra vaccination of children from 0-3 years. As well as cumulative information materials for professionals and the public about the above-standard vaccination of children from 0-3 years.

Willi Jäger (jaeger@iwr.uni-heidelberg.de) Institut für Angewandte Mathematik, Universität Heidelberg Abstract: Synovial fluid is a polymeric liquid which generally behaves as a viscoelastic fluid due to the presence of polysaccharide molecules called hyaluronan. In this thesis, we study the biological and biochemical properties of synovial fluid, its complex rheology and interaction with synovial membrane during filtration process. From the mathematical point of view, we model the synovial fluid as a viscous incompressible fluid for which we develop a novel generalized power-law fluid model wherein the power-law exponent depends on the concentration of the hyaluronan. Such a model is adequate to describe the flows of synovial fluid as long as it is not subjected to instantaneous stimuli. Moreover, we try to find a suitable linear viscoelastic model...

Tese de mestrado em Química Inorgânica Biomédica (Aplicações em Diagnóstico e Terapia), apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2008
O trabalho descrito nesta tese incidiu sobre a síntese, caracterização e avaliação biológica de complexos de Ga(III) e oxocomplexos de Re(V) com ligandos tridentados- (N,N',O) derivados do pirazolo. Era esperado obter complexos de Ga(III) com interesse potencial para o desenvolvimento de agentes antitumorais e oxocomplexos mistos de Re(V) do tipo 3+2 com características adequadas para ser usados como compostos modelo no desenvolvimento de radiofarmacos-99mTc. Sintetizou-se uma nova família de bases de Schiff (L1H-L4H) por condensação de N-(2-aminoetil)pirazolo com derivados de salicilaldeído contendo diferentes substituintes no anel aromático. A redução de L1H, L2H e L4H com NaBH4 permitiu obter ligandos relacionados (L5H-L7H) que apresentam uma amina central como grupo coordenante. L1H-L7H permitiram obter complexos homolépticos (1-7) do tipo GaL2 + em que as bases de Schiff (L1-L4) se encontram coordenadas de modo tridentado e meridional (complexos 1-4) e os derivados amina (L5-L7) de modo tridentado e facial (complexos 5-7). A avaliação in vitro dos diferentes compostos em linhas celulares cancerígenas de origem humana (MCF-7 e PC-3) revelou que os complexos 4 e 7, estabilizados com ligandos (L4 e L7) que contem substituintes Cl nas posições 3 e 5 do anel fenolato, sao aqueles que apresentam maior actividade citotóxica. Na linha celular PC-3, a actividade citotóxica de 4 e 7 e significativamente superior a observada para a cisplatina L1H e L5H foram ainda usados para estabilizar a unidade [Re=O]3+, tendo permitido a síntese dos oxodicloretos mer-[Re(O)(Cl)2(L1)] (8) e fac-[Re(O)(Cl)2(L5)] (9). O estudo da reactividade de 8 e 9 face a diferentes substratos potencialmente bidentatos (1,2-etanodiol, ácido oxálico, ácido malónico, 1,2-mercaptoetanol, 1,2- etanoditiol) apenas conduziu com êxito à síntese dos oxocomplexos mistos 3+2 fac- [Re(O)(L5)(OCH2CH2O))] (10) e fac-[Re(O)(L5)(C2O4))] (11). O complexo 10 reage rapidamente com glutationa o que sugere que estes compostos mistos de Re(V) não apresentam estabilidade suficiente para ser explorados no desenvolvimento de radiofármacos
The work described in this thesis deals with the synthesis, characterization and biological evaluation of Ga(III) complexes and 3+2 mixed-ligand Re(V) oxocomplexes anchored by tridentate-(N,N',O) pyrazolyl-containing ligands, aiming at their use in the design of novel antitumor drugs and 99mTc-radiopharmaceuticals, respectively. A new family of pyrazolyl-containing Schiff bases (L1H-L4H) were synthesized by reaction of N-(2-aminoethyl)pyrazole with adequate salicylaldehyde derivatives containing different substituents at the aromatic ring. Reduction of L1H, L2H and L4H with NaBH4 afforded a series of related ligands (L5H-L7H) bearing a central amine as coordinating group. L1H-L7H were used to prepare homoleptic complexes of the type GaL2 +. In these complexes the Schiff bases (L1-L4) act as tridentate and meridional chelators (complexes 1-4) while the corresponding amine derivatives (L5-L7) coordinate to the metal in a tridentate and facial fashion (complexes 5-7). The in vitro evaluation of the different compounds in human tumor cell lines (MCF-7 and PC-3) has shown that complexes 4 and 7, anchored by L4 and L7 which contain Cl substituents at the 3 and 5 positions of the phenolate ring, display the highest cytotoxic activity. In the PC-3 cell line, 4 and 7 are considerably more cytotoxic than cisplatin. L1H and L5H were also used to stabilize the [ReO]3+ core affording the oxodichlorides mer-[Re(O)(Cl)2(L1)] (8) and fac-[Re(O)(Cl)2(L5)] (9). The reactivity of 8 and 9 was evaluated towards a variety of potentially bidentate substrates (1,2- ethanediol, oxalic acid, malonic acid, 1,2-mercaptoethanol, 1,2-ethanedithiol). These reactivity studies allowed uniquely the synthesis of the 3+2 mixed-ligand complexes fac-[Re(O)(L5)(OCH2CH2O))] (10) and fac-[Re(O)(L5)(C2O4))] (11). Complex 10 reacts promptly with glutathione suggesting that these mixed-ligand Re(V) complexes do not display enough stability to be further explored in radiopharmaceutical research

Abstract:

This diploma thesis deals with the validation of spectral average cross-sections (SACS) of 55 Mn(n,2n)54 Mn, 90 Zr(n,2n)89 Zr, 127 I(n,2n)126 I reactions in well-defined LR-0 reactor spectrum. The measurement of SACS for selected reactions is of high interest because they are used for the practical reactor dosimetry. Various experiments for description of neutron field in reactor and detector characterization, which are necessary for validation, are described. The spectral average cross-sections are derived from Net Peak Areas of irradiated samples measured using a semiconductor high purity germanium detector. Obtained result were compared with MCNP6 calculations using ENDF/B-VII.0, ENDF/B-VII.1, JEFF-3.1, JEFF-3.2, JENDL-3.3, JENDL-4, ROSFOND-2010, CENDL-3.1 and IRDFF nuclear data libraries. Notable discrepancies were found in 90 Zr(n,2n)89 Zr and 127 I(n,2n)126 I reactions. This thesis also contains a theoretical basis for the interaction of neutrons with matter.

Abstract:

L'objet de ce mémoire est de présenter le travail effectué au cours de cette thèse qui était de caractériser électriquement et de modéliser le transport électrique de trois architectures de transistors MOS pour des filières 50nm et en deçà : CMOS Si à oxyde ultrafin, nMOS Si:C et pMOS SiGe. Afin d'étudier les effets de canaux courts sur ces dispositifs nous avons proposé et/ou optimisé plusieurs procédures d'extraction de paramètres ainsi que plusieurs modèles physiques analytiques décrivant le comportement des principaux paramètres électriques de ce type de transistors aux longueurs de grille décananométriques. Ainsi, une méthode expérimentale complète et un modèle pour la partition du courant de grille ont été validés pour les transistors à oxyde ultrafin. Une optimisation de la méthode Split C-V pour les canaux courts a été validée donnant de précieux renseignements sur la mobilité des transistors MOS ultracourts. Un modèle a été validé pour le bruit 1/f des transistors à canal enterré SiGe sub-0,1μm. Toutes ces méthodes nous ont permis de montrer que les transistors à oxyde ultrafins gardaient de très bonne propriétés de transport électrique jusqu'à 30nm de longueur de grille, que les nMOS Si:C était une alternative fiable au fort dopage canal pour contrôler les effets de canaux courts des nMOS sub-0,1μm et que les pMOS SiGe avaient un niveau de bruit 1/f plus faible en forte inversion même aux longueurs de grille décanamométriques
