Systèmes à retards : platitude en génie des procédés et contrôle de certaines équations des ondes

Le travail presente s'inscrit dans le cadre de la platitude, theorie recente dans la domaine du controle des systemes. Nous presentons des realisations industrielles en genie des procedes et des contributions theoriques dans le domaine des equations aux derivees partielles. A partir d'applications industrielles realisees avec le groupe totalfinaelf et aujourd'hui en service dans les usines concernees, nous montrons l'interet pratique de la platitude dans le domaine du controle des procedes : gestion de grands transitoires, prise en compte explicite des non-linearites, des retards, des contraintes nous traitons ensuite un ensemble d'exemples physiques de systemes regis par des equations des ondes. En reecrivant ces equations aux derivees partielles et leurs conditions limites comme des equations a retards, nous exhibons une parametrisation de leurs trajectoires etablissant ainsi la propriete de platitude de ces systemes. Il est alors possible de prouver de maniere constructive la commandabilite de ces systemes en calculant des trajectoires entre differents etats. Tous ces exemples, ou les retards jouent des roles a chaque fois differents, nous permettent de mettre en valeur l'importance pratique et theorique de la propriete de platitude dans le domaine du genie des procedes et du controle des equations des ondes.
Détection de contours couleur par coopération de modèles statistiques et de mesures psychophysiques de perception

Parmi les facteurs influencant directement notre attention visuelle, la qualite des contours prend une part preponderante dans le resultat final. Des lors, une detection correcte et perceptuellement significative de ceux-ci est necessaire. Nous proposons un detecteur de contours couleur base sur une modelisation statistique de l'image et des mesures psychophysiques de perception. Les resultats obtenus permettent de conclure a un gain substantiel vis-a vis du rendu des contours pour des images de complexite relativement importante.
Staff stress in the care of the critically ill and dying child.

This chapter has provided a theoretical model of staff stress in the care of critically ill and dying children. The stress that staff members experience is a reflection of stressors inherent in the patient care environment as well as those mediating factors which the individual brings into the work setting from his or her personal life. These factors may either strengthen the individual in a stressful situation or may make the caregiver more vulnerable to a stress reaction. Stress may be manifested in physical or psychological symptoms or in difficulties in the person's social, family or occupational life. Specific suggestions were given for coming with some of these manifestations of stress.
Méthodes probabilistes d'analyse de fiabilité dans la logique combinatoire

Les circuits numeriques utilises dans des domaines aussi varies que le medical, spatial, automobile ou nucleaire ont besoin d'une tres forte fiabilite. La reduction progressive de la tension d'alimentation et l'integration croissante des produits electroniques affecte la sensibilite du systeme a l'apparition de fautes (permanentes ou transitoires). Les fautes transitoires ont ete largement dominants dans le taux total de SER (Soft Error Rate) des memoires et elements de sequentiels. Ainsi, les techniques de correction et prevention pour ces elements sont bien connues. Par contre, la contribution au SER due aux elements de logique combinatoire est en croissance, et il est prevue qu'elle devient dominante avec la reduction progressive de la taille de la technologie CMOS. Ainsi, il y a un reel besoin de pallier le manque de modeles et methodologies qui prennent en compte l'effet de la logique combinatoire dans la perte de fiabilite. Deux approches existe pour cette problematique : 1- Techniques d'injection de fautes 2 - Modeles analytiques Le travail presente dans cette these pour sur l'approche analytique, ou approche probabiliste. D'abord, une analyse en profondeur de l'etat de l'art est propose, mettant en evidence les limitations principales de ce type d'approche. Deuxiemement, des nouvelles approches sont proposees, ameliorant la performance des approches existants. Des nouvelles metriques concernant l'analyse FMDEA et durcissement selectif sont aussi proposees. Finalement, les approches sont validees en comparant leur performance avec les principales techniques deja existantes.
Reinforcement learning based scheduling in semiconductor final testing

Semiconductor test scheduling problem is a variation of reentrant unrelated parallel machine problem considering multiple resources constraints, intricate {product, tester, kit, component} eligibility constraints, and sequence-dependant setup times, etc. A multi-step reinforcement learning (RL) algorithm called Sarsa(λ,k) is proposed and applied to deal with it. Allowing enabler reconfiguration, the capacity of the test facility is expanded and scheduling optimization is performed at the component level. In order to apply Sarsa(λ,k), the scheduling problem is transformed into an RL problem by defining state representation, constructing actions and the reward function. Experiments show that Sarsa(λ,k) outperforms the scheduling method in industry and validate the effectiveness of Sarsa(λ,k) to solve the scheduling problem.
Glial progenitor cells of the nerve fiber layer of the olfactory bulb: Effect of astrocyte growth media

There are two morphologically distinct types of glial cells (i.e., ensheathing cells and astrocytes) in the nerve fiber layer (NFL) of the adult mammalian olfactory bulb. Ensheathing cells provide ensheathment for olfactory axons, whereas astrocytes occupy the interfascicular spaces of the olfactory NFL. During embryonic development, however, only one type of glial cell is found in this layer of the olfactory bulb, namely, the ensheathing cell. Even though ensheathing cells take up residence within the CNS, they are actually derived from the olfactory placode. Far less is known about the developmental origin of interfascicular astrocytes, which arise either from the glial progenitor cells that give rise to ensheathing cells or from astrocyte precursor cells that migrate into the NFL from deeper layers of the bulb primordium. In the present study, enriched populations of ensheathing cells were grown in vitro in media known to promote the growth and differentiation of astrocytes to determine whether ensheathing cell progenitors could differentiate into astrocytes. These media failed to induce the appearance of astrocytes in the ensheathing cell cultures. It was concluded that the astrocytes of the NFL most likely arise from progenitor cells that migrate into this layer from deeper parts of the developing bulb. © 1993 Wiley‐Liss, Inc.
Plasma homocysteine levels and mortality in patients with coronary artery disease.

BACKGROUND Elevated plasma homocysteine levels are a risk factor for coronary heart disease, but the prognostic value of homocysteine levels in patients with established coronary artery disease has not been defined. METHODS We prospectively investigated the relation between plasma total homocysteine levels and mortality among 587 patients with angiographically confirmed coronary artery disease. At the time of angiography in 1991 or 1992, risk factors for coronary disease, including homocysteine levels, were evaluated. The majority of the patients subsequently underwent coronary-artery bypass grafting (318 patients) or percutaneous transluminal coronary angioplasty (120 patients); the remaining 149 were treated medically. RESULTS After a median follow-up of 4.6 years, 64 patients (10.9 percent) had died. We found a strong, graded relation between plasma homocysteine levels and overall mortality. After four years, 3.8 percent of patients with homocysteine levels below 9 micromol per liter had died, as compared with 24.7 percent of those with homocysteine levels of 15 micromol per liter or higher. Homocysteine levels were only weakly related to the extent of coronary artery disease but were strongly related to the history with respect to myocardial infarction, the left ventricular ejection fraction, and the serum creatinine level. The relation of homocysteine levels to mortality remained strong after adjustment for these and other potential confounders. In an analysis in which the patients with homocysteine levels below 9 micromol per liter were used as the reference group, the mortality ratios were 1.9 for patients with homocysteine levels of 9.0 to 14.9 micromol per liter, 2.8 for those with levels of 15.0 to 19.9 micromol per liter, and 4.5 for those with levels of 20.0 micromol per liter or higher (P for trend=0.02). When death due to cardiovascular disease (which occurred in 50 patients) was used as the end point in the analysis, the relation between homocysteine levels and mortality was slightly strengthened. CONCLUSIONS Plasma total homocysteine levels are a strong predictor of mortality in patients with angiographically confirmed coronary artery disease.
K-REGULAR GRAPH WITH DIAMETER 2

A regular graph with vertices of degree k is called a k regular graph or regular graph of deree k . G is said to be strongly regular if there are also integers  and  such that: every two adjacent vertices have  common neighbours and every two non-adjacent vertices have  common neighbours. A graph of this kind is sometimes said to be an ( , , , ) SRG n k   . The length ( , ) ( , ) max u v d u v of the "longest shortest path" (i.e., the longest graph geodesic) between any two vertices ( , ) u v of a graph, where ( , ) d u v is a graph distance. k n denotes the maximum number of vertices in a k regular graph with diameter 2. We will prove that 2 5( 1) 1 k k n k     and determine k n for some special values of k .
Efficacy of Deferasirox as an Oral Iron Chelator in Paediatric Thalassaemia Patients.

INTRODUCTION Thalassaemia Major patients require frequent blood transfusion leading to iron overload. Excessive iron gets deposited in vital organs and leads to dysfunction of the heart, liver, anterior pituitary, pancreas, and joints. Our body has limited mechanism to excrete iron, so patients with iron overload and its complications need safe and effective iron chelation therapy. AIM To assess the efficacy of Deferasirox (DFX) as an iron chelator, with specific reference to reduction in serum ferritin level. MATERIALS AND METHODS This is a prospective; observational study done in 45 multitransfused Thalassaemia Major Children receiving DFX therapy at registered Thalassaemia society Raipur Chhattisgarh. DFX was given in an initial dose of 20 mg/kg/day and according to response increased to a maximum of 40 mg/kg/day. Serum ferritin level was estimated at time of registration and at every three monthly intervals (four times during study period). The primary end point of the study was change in serum ferritin level after 12 months of DFX therapy. RESULTS The mean serum ferritin before DFX therapy of all cases was 3727.02 ng/mL. After 12 months of mean dose of 38 mg/kg/day of DFX, the mean decline in serum ferritin was 1207.11 ng/mL (drop by 32.38%, p-value <0.001). CONCLUSION DFX monotherapy has a good safety profile and effectively chelates total body iron in Thalassaemia major patients.
Amyloid fibril protein nomenclature: 2010 recommendations from the nomenclature committee of the International Society of Amyloidosis

A system of amyloid fibril nomenclature based on the chemical identity of the amyloid fibril forming protein is recommended. This system has been in use for approximately 40 years, but current literature remains confused with clinical and histochemical designations used when the amyloid disease processes were poorly understood. To be designated an amyloid fibril protein, the protein must occur in tissue deposits and exhibit affinity for Congo red and green birefringence when viewed by polarisation microscopy. Furthermore, the protein must have been unambiguously characterised by protein sequence analysis (DNA sequencing in the case of familial diseases). Current nomenclature lists of 27 human and nine animal fibril proteins are provided together with a list of eight inclusion bodies that exhibit some of the properties of amyloid fibrils.
Skeleton Parsing in Chinese: Annotation Scheme and Guidelines

This paper presents my manual skeleton parsing on a sample text of approximately 100,000 word tokens (or about 2,500 sentences) taken from the PFR Chinese Corpus with a clearly defined parsing scheme of 17 constituent labels. The manually-parsed sample skeleton treebank is one of the very few extant Chinese treebanks. While Chinese part-of-speech tagging and word segmentation have been the subject of concerted research for many years, the syntactic annotation of Chinese corpora is a comparatively new field. The difficulties that I encountered in the production of this treebank demonstrate some of the peculiarities of Chinese syntax. A noteworthy syntactic property is that some serial verb constructions tend to be used as if they were compound verbs. The two transitive verbs in series, unlike common transitive verbs, do not take an object separately within the construction; rather, the serial construction as a whole is able to take the same direct object and the perfective aspect marker le. The skeleton-parsed sample treebank is evaluated against Eyes & Leech (1993)s criteria and proves to be accurate, uniform and linguistically valid.
Wake and Drag Manipulation of a Bluff Body Using Fluidic Forcing

La reduction de la trainee aerodynamique des vehicules terrestres est un defi actuel dans l’industrie automobile. La region de basse pression du sillage a l’arriere des voitures est responsable d’une part importante de la resistance a l’avancement. Cette etude porte sur le developpement de nouvelles strategies de manipulation de l’ecoulement autour de ces geometries dans le but de reduire la trainee. Afin d’atteindre ces objectifs, nous explorons experimentalement les effets d’un forcage fluidique sur le sillage et la trainee d’un corps au culot droit. Des jets periodiques emis aux bords de fuite du modele, tangentiellement a l’ecoulement principal et avec des frequences et amplitudes variables sont utilises pour forcer le sillage. Selon les conditions du controle, trois phenomenes sont principalement observes. Premierement, sur la plage des frequences comprenant celle du lâcher tourbillonnaire, les jets pulses sont convectes et modifient l’entrainement de fluide vers la region de recirculation ainsi que l’evolution des instabilites de la couche cisaillee. Cette dynamique complexe a comme consequence l’augmentation de la trainee du corps. De plus, une resonance subharmonique apparait quand les jets pulses sont emis avec des frequences voisines de deux fois la frequence du mode global. Une importante augmentation de la trainee est alors mesuree et correlee a une forte amplification des mouvements du sillage. Une augmentation de la frequence de pulsation se traduit par un effet de vectorisation des couches cisaillees. En outre, une diminution de l’intensite turbulente du sillage proche ainsi qu’une reduction de l’entrainement de fluide le long des couches cisaillees sont mesures, correspondant a une reduction globale de l’energie cinetique turbulente de l’ecoulement. Le couplage de ces effets est responsable d’une augmentation de la pression au culot et de la reduction de la trainee. Il est important de noter que ces trois regimes d’actuation sont independants des modes de brisure de symetrie existant dans ces ecoulements, qui sont analyses ici par des etudes parametriques de sensibilite aux perturbations. Les aspects physiques de ces phenomenes sont discutes par des mesures de la trainee, de la pression parietale et de la vitesse avec differentes conditions de l’ecoulement et du controle. L’addition d’une surface courbee au voisinage du jet pulse permet de profiter d’un effet Coanda et augmente les reductions de trainee jusqu'a 20%dans le regime instationnaires. De facon generale, l’effet Coanda amplifie non seulement la recuperation de la trainee mais preserve aussi les effets de la pulsation haute frequence sur l’ecoulement turbulent. Ces resultats encouragent le developpent des actionneurs fluidique pour l’utilisation en aerodynamique des vehicules et fournissent un complement pour notre comprehension sur la trainee des corps non profiles et sa manipulation.
Observation et commande de la machine asynchrone

Le travail de recherche effectu'e dans cette these a ete principalement consacre aux problemes d'observation et de commande des moteurs asynchrones sans capteurs mecaniques. Deux contributions principale ont ete faites en exploitant judicieusement le concept de grand gain. La premiere contribution est un observateur du type grand gain qui permet de realiser une estimation relativement pr'ecise des variables d'etat mecaniques et magnetiques des moteurs asynchrones a partir des mesures disponibles des courants et tensions statoriques. Le gain d'observation a ete judicieusement modifie pour des considerations de faisabilite des calculs lorsque le moteur est amene a fonctionner dans des conditions incompatibles avec sa condition d'observabilite. Cet observateur a ete particulierement utilise pour concevoir un asservissement des moteurs asynchrones sans capteur mecaniques a partir d'un systeme de commande avec retour d'etat du type grand gain. La seconde contribution est une synthese d'observateurs adaptatifs du type grand gain qui permettent d'estimer conjointement les variables d'etat et un ensemble de combinaisons des parametres d'un moteur asynchrone a partir des mesures des courants et tentions statoriques avec et sans mesure de la vitesse mecanique. Un observateur adaptatif a ete particulierement combine avec un systeme de commande avec retour d'etat du type grand gain pour concevoir un systeme de commande adaptative permettant de preserver les performances requises en asservissement des moteurs asynchrones sans capteurs magnetiques en depit d'une meconnaissance de leurs parametres.
Evolutionary Loss of Parasitism by Nematodes? Discovery of a Free-Living Filaroid Nematode

A cattle-drinking pool in nature reserve “Zwin” on the Belgian coast contained free-living third-stage infective filaroid juveniles. These juveniles clearly differ morphologically from all known nematodes. Morphological and molecular analyses indicate a position within the Filaroidea. The aberrant biology of this nematode, namely, a free-living stage in an aquatic environment, is unknown within this superfamily, and the evolution of the parasitic phenotype to a free-living state is generally thought to be unlikely. However, the obtained placement in the small subunit molecular phylogenetic tree suggests that this free-living stage is most likely a secondary adaptation. It is reasonable to assert that nematodes with complex life cycles still have the genetic potential for a reversion from parasitism to a (partial) free-living stage.

ScienceDirect 20 th International Conference on Knowledge Based and Intelligent Information and Engineering Systems Knowledge-based framework for intelligent emotion recognition in spontaneous speech

Automatic speech emotion recognition plays an important role in intelligent human computer interaction. Identifying emotion in natural, day to day, spontaneous conversational speech is difficult because most often the emotion expressed by the speaker are not necessarily as prominent as in acted speech. In this paper, we propose a novel spontaneous speech emotion recognition framework that makes use of the available knowledge. The framework is motivated by the observation that there is significant disagreement amongst human annotators when they annotate spontaneous speech; the disagreement largely reduces when they are provided with additional knowledge related to the conversation. The proposed framework makes use of the contexts (derived from linguistic contents) and the knowledge regarding the time lapse of the spoken utterances in the context of an audio call to reliably recognize the current emotion of the speaker in spontaneous audio conversations. Our experimental results demonstrate that there is a significant improvement in the performance of spontaneous speech emotion recognition using the proposed framework. c © 2016 The Authors.

High Expression of SOX2 and OCT4 Indicates Radiation Resistance and an Independent Negative Prognosis in Cervical Squamous Cell Carcinoma

Radiotherapy (RT) as a preoperative or postoperative adjuvant or primary treatment is the most common management modality for locally advanced cervical cancer. Radioresistance of tumor cells remains a major therapeutic problem. Consequently, we aimed to explore if the stem cell biomarkers SOX2 and OCT4 protein could be used to predict radioresistance in patients with locally advanced cervical squamous cell carcinoma (LACSCC). These 132 patients were divided into two groups (radiation-resistant and radiation-sensitive groups) according to progress-free survival (PFS). Using pretreatment paraffin-embedded tissues, we evaluated SOX2 and OCT4 expression using immunohistochemical staining. The percentage of overexpression of SOX2 and OCT4 in the radiation-resistant group was much higher than that in the radiation-sensitive group (p<0.001 and p <0.001, respectively). The patients with high expression of SOX2 and OCT4 showed a shorter PFS than those with low expression. Our study suggests that the expression of SOX2 and OCT4 in tumor cells indicates resistance to radiotherapy and that these two factors were important predictors of poor survival in patients with LACSCC (hazard ratio [95% CI], 2.294 [1.013, 5.195] and 2.300 [1.050, 5.037], respectively; p=0.046 and p=0.037, respectively).
