This thesis focuses on the automatic recognition of human stress during stress-inducing interactions (public speaking, job interview and serious games), using audio and visual cues.In order to build automatic stress recognition models, we used audio cues computed from subjects' voice captured via a lapel microphone, and visual cues computed either form subjects' facial expressions captured via a webcam, or subjects' posture captured via a Kinect. Part of this work is dedicated to the study of information fusion form those various modalities.Stress expression and coping are influenced both by interpersonal differences (personality traits, past experiences, cultural background) and contextual differences (type of stressor, situation's stakes). We evaluated stress in various populations in data corpora collected during this thesis: social phobics in anxiety-inducing situations in interaction with a machine and with humans; apathologic subjects in a mock job interview; and apathologic subjects interaction with a computer and with the humanoid robot Nao. Inter-individual and inter-corpora comparisons highlight the variability of stress expression.A possible application of this work could be the elaboration of therapeutic software to learn stress coping strategies, particularly for social phobics.Key words: stress, social phobia, multimodal stress detection, stress audio cues, stress facial cues, stress postural cues, multimodal fusion

Oxidative stress is a biological phenomenon resulting from an imbalance between oxidant and antioxidant species which can be involved in the early stages of many pathologies such as cancer or neurodegenerative diseases. The detection of molecules involved in the oxidative stress is a major issue in terms of public health. Due to its simplicity, fast-response time and low cost, electrochemistry is a method of interest for the detection of dissolved oxygen and hydrogen peroxide, two precursors of more deleterious reactive species in a biological medium. In this work a study of the electrochemical behavior of O2 and H2O2 under neutral conditions was performed by cyclic and steady-state voltammetries, first on bulk unmodified materials (glassy carbon and gold). In order to be further used as a reference and fill a lack in the literature, the charge transfer coefficients were determined for O2 reduction and H2O2 oxidation using Tafel and Koutecky-Levich methods and were compared to those obtained in acidic and basic media. In a second part, gold nanoparticles functionalized glassy carbon electrodes were prepared by two ways: direct electrodeposition from a gold precursor and deposition by adsorption of colloidal gold solution synthesized in aqueous medium. To demonstrate the electrocatalytic properties of those gold nanoparticles, the charge transfer coefficients were determined for O2 reduction and H2O2 oxidation and compared with those obtained on bulk materials. From the different materials used, separate calibrations were made for the two target molecules, and then a simultaneous detection was proposed by cyclic voltammetry to achieve the proof of concept for future sensor

Water stress affect the yield and the crop quality. For more than twenty years, remote sensing allowed several tools developments to assess water stress detection using sensors and model such as Crop Water Stress Index (CWSI). Sparse crop can generate error in the interpretation of this index. The use of an imaging-radiometer combined to a high spatial resolution visible image help to remove this weakness. This study present a new water stress index based in the use of infrared thermography. A first dataset was taken from greenhouse experimental set up on potatoes species (Highlite and Chieftain) using an hand-held imaging-radiometer (ThermaCAM SC 2000). Repeated measurements were made for water-stress induced plants and for well irrigated plants at different growing stages. The study showed that an early detection of water deficit by infrared thermography is possible as well as the detection of the significant response of plant to heat stress and leaf area change based on water stress intensity. Temperature differences between crop canopy and air (Tc - Ta) are strongly correlated with the water stress. The study has permitted the development of a new index named Area Water Stress Index (AWSI) and the results obtained with this index for water stress detection are very encouraging.

Dendritic cells (DCs) are the most important antigen presenting cells. In response to inflammatory stimulation, DCs display a distinct pattern of differentiation that exhibits specific mechanisms to control the immune response. In this work the responses to dsRNA were analyzed. We have shown that in response to a mimic of dsRNA, polyriboinosinic:polyribocytidylic acid (poly I:C), DCs mount a specific integrated stress response during which the transcription factor ATF4 and the growth arrest and DNA damage-inducible protein 34 (GADD34), a phosphatase 1 (PP1) cofactor, are expressed. GADD34 is important to counteract phosphorylation of eIF2α by PKR. In contrast to murine embryonic fibroblasts (MEFs), DCs resist to protein synthesis inhibition induced in response to cytosolic dsRNA. Nevertheless, GADD34 expression does not have a major impact on global protein synthesis. Importantly, GADD34 was shown to be absolutely required for type I-IFN and IL-6 production by MEFs and DCs in response to dsRNA. This observation has important implications in linking pathogen detection with the integrated stress response pathways. The importance of this link is further underlined by the extreme susceptibility of GADD34-deficient fibroblasts and neonate mice to Chikungunya virus infection

This thesis deals with the using of accelerating data and regression model selection for high technology field: semiconductor chips. The accelerating trail gives us regression frameworks. The aim of the accelerating test consists on fitting the logarithm of the lifetime through the use of some function f, called the acceleration function. However, accelerating data may have misleading and complex comportment. In order to adapt the model with such data, we have proposed to detect the changes on the comportment of the acceleration function. We have considered a collection of piecewise acceleration models candidate to the estimation. For each model candidate we have estimated the least-squares estimation. And we have selected the final estimator using a penalized criterion. The penalized estimator is optimal approximation of the reality since the quadratic risk of penalized estimator is bounded by the minimal risk upon every least-squares estimators candidates. Moreover, this oracle inequality is non asymptotic. Furthermore, we have considered classical reliability cases: the Lognormal case associating with some fatigue failure, and the Weibull case associating with some choc failure. Lastly we have implemented model selection tools in order to realise survey study without a priori on the acceleration models and to use overstress trials

Lucerne (Medicago sativa) is an autotetraploid forage legume, whose breeding could beneficiate from allele mining. This strategy is based on the natural diversity and consists in seeking alleles with a potential effect on the phenotype. The interest of this approach was evaluated by studying five genes of agronomic interest: CAD1 and CCoaOMT (digestibility), CONSTANS-like (forage yield), NHX1 (salt tolerance) and WXP1 (drought tolerance). The diversity of these five genes was evaluated by sequencing 387 genotypes of cultivated accessions and 20 genotypes of wild accessions. The results confirmed a bottleneck during lucerne domestication and selection. CONSTANS-like and WXP1 were very variable whereas CAD1, CCoaOMT and NHX1 contained very few variants. Variants with a potential strong impact on the phenotype were identified in conserved parts of protein sequence within the Faboideae. The impact on phenotype was studied for two mutations of the CONSTANS-like gene: constans-634, causing a premature stop codon and constans-4111, located in a conserved region of the gene. Genotypes carrying one to three doses of the mutations (AAAB, AABB and ABBB) were polycrossed in order to obtain offsprings with every allele combination (AAAA, AAAB, AABB, ABBB and BBBB). KASPar markers were developed to determine the mutation doses in offspring progeny. No homozygous genotype was found for constans-634 in the 1505 offspring progeny. This mutation induced a premature flowering of three days for the genotypes carrying three doses of the mutation. The mutation constans-4111 induced an additive effect on stem height and the homozygous genotypes without the variant where on average 11.8 cm shorter than homozygous genotypes carrying three or four doses of the variant. The application of allele mining strategy in plant schemes of heterozygous autotetraploid species was discussed
