Contribution à la détection des défauts statoriques des actionneurs à aimants permanents : Application à la détection d'un défaut inter-spires intermittent et au suivi de vieillissement

Grâce a leurs avancees techniques en termes de poids, performances et fiabilite, les machines synchrones sont de plus en plus utilisees dans le domaine de transport et en particuliers dans l’aeronautique. Les strategies de maintenances de ces systemes electriques sont alors indispensables afin d'eviter des surcouts lies a des temps d'arret non planifies. Ce document propose une analyse des consequences d'un defaut inter-spires intermittent naissant dans l'enroulement statorique d'une Machine Synchrone a Aimants Permanents (MSAP). Ce type de defaut correspond a l'etat peu avance d'un futur court-circuit permanent. Jusqu'a present, les etudes menees se sont limitees a la detection de courts-circuits inter-spires permanents. L'objectif de cette analyse est de definir une methode de detection de ce type de defaut qui soit facile a mettre en œuvre. A partir d'une etude analytique du courant statorique d'une MSAP controlee en courant en presence de court-circuit intermittent, nous avons etudie l'impact des differentes grandeurs influencant la perturbation du courant. Nous avons constate que la forme de la perturbation creee par le defaut etait toujours la meme et qu'elle etait la signature du defaut intermittent dans le courant. Par la suite cette etude analytique a ete validee experimentalement. Dans la partie suivante nous avons etudie la sensibilite des methodes de detection des courts-circuits inter-spires permanents appliquees au cas du court-circuit intermittent. Ces methodes se sont revelees inadaptees pour la detection du defaut etudie dans ce travail. Nous avons donc propose une methode dediee qui est basee sur la detection de la signature du defaut et qui utilise une transformation en ondelette adaptee. Il s'agit d'une methode de detection de forme qui permet non seulement de detecter le defaut intermittent mais aussi de le distinguer des autres types de defauts. La performance de la methode a ete validee par les resultats de simulation et de manipulation. Dans une derniere partie, une etude plus generale sur le suivi de vieillissement des enroulements est proposee. Elle est basee sur le suivi de l'evolution des courbes d'admittance hautes frequences d'un bobinage au cours du temps en utilisant les fonctions de transfert de ce dernier.
Context parallelism in an indexical programming language

Indexical programming languages enrich conventional programming languages by allowing the meanings of program constructs to depend on an implicit context. In an indexical program, values at different contexts can potentially be evaluated an parallel, resulting in context parallelism. This paper formally defines context parallelism in the indexical language mLucid, by a variable-value dependency graph (VDG) derived from the denotational semantics of the language. Based on different abstractions of the VDG, three levels of context parallelism: fine, medium, and coarse parallelism are defined, which reflect different levels of parallel computations specified by the indexical program. <<ETX>>
MODELO CONCEITUAL A PARTIR DAS TEORIAS BORDAS-SCRIPT APLICADO A UM EVENTO TURÍSTICO

Na industria do turismo, a competitividade entre os destinos geralmente nao esta centrada apenas no produto turistico (ambiental, transporte, recursos, hospitalidade, servicos turisticos, etc.), mas no destino turistico como um conjunto integrado de clusters que propiciam uma experiencia memoravel para o turista, a partir da co-criacao de valor. Este estudo propoe que a popularidade dos destinos turisticos pode ser reforcada por uma combinacao de fatores como: competividade, satisfacao e lealdade a partir de uma experiencia autentica do consumidor de turismo, ou seja, do valor percebido a partir da logica de servico dominante (SDL – Service Dominant Logic). O objetivo desta pesquisa foi apresentar um modelo conceitual baseado no modelo de Bordas e na teoria de Script para avaliar os fatores de competitividade e experiencia emocional dos consumidores em um evento turistico. Procurou-se discutir neste estudo como a competitividade dos clusters, baseada no modelo de Bordas, na teoria de Script e na logica de servico dominante, pode proporcionar uma experiencia memoravel que implique na satisfacao do turista e sua consequente lealdade para com o destino turistico.
Performance Optimization of the Multi-Pumped Raman Optical Amplifier using MOICA

In order to achieve the best gain profile for multi pump distributed Raman amplifiers in Wavelength Division Multiplexing (WDM) transmission systems, the power and wavelength of pumps, the type of pumping configuration and the number of pump signals are the most important factors. In this paper, using a Multi-Objective Imperialist Competition Optimization Algorithm (MOICA) with lowest power consumption and lowest number of pumps, we propose the most uniform gain profile for two types of pumping configurations in S- band and compare the results. Considering the design conditions including the type of pumping configuration, fiber length, fiber type and number of pump signals and using the multi-objective algorithm, we propose a method which can be used to achieve a gain level in which the amplifier has the lowest power consumption and lowest gain ripple. According to this, we can design a powerful WDM transmission system by Distributed Raman Amplifier (DRA) with a good performance and efficiency.
[A reinterpretation of period fertility by birth order in Italy from 1950 to 1990, taking into consideration the parity structure].

A comparative analysis of the evolution of Italian fertility during the period 1950-1990 was conducted, and the procedure of indirect estimation was used by means of the probability of age-specific fertility and parity-specific fertility of the mother. The total fertility rate (TFR) was the indicator constructed from the quotient specific to age, and the total fertility rate for parity (TFRP) was the indicator for age and parity that was constructed via the quotient specific to age and parity. During 1950-1990 the TFR changed from 2606.9 children to 1278.6 children per 1000 women. The TFR stayed above 2300 per 1000 women up to 1975. Between 1965 and 1990 the TFR decreased by 55.2%, while the TFR for parity decreased by 46.9%, which meant that the average number was 1397.4 children per 1000 women, while the TFRP was 1221.7 children per 1000 women. This meant that the TFR for age was amplified by 175 children, while the parity-specific TFR was lower. The TFR for first-order births increased up to 1975; and this increase was higher for age than for age and parity. As of 1975-76 the first-order TFR and first-order TFR for parity declined with differing velocity. The TFR for age underwent a veritable collapse down to 600 children per 1000 women, while the TFR for age and parity dropped only slowly to 800 children per 1000 women by 1990. Over the years, there were more women who had no children, especially towards the end of the 1970s. By 1963-1964 the baby boom had exerted its behavioral and structural influence, and the decline of fertility relevant to age and parity began. First-order births were rapidly dropping until the 1980s, when the equilibrium of the present day was established. During 1985-1995 first-order births stabilized, and average age did not increase any more with respect to age and parity, demonstrating that the recent forceful decline of parity and fertility has diminished.
Patterns of Health Insurance Coverage among Rural and Urban Children

Despite the potential for the State Children’s Health Insurance Program to improve the health care coverage of rural children, the expansion of public health insurance to children in rural areas may be hampered by a lack of understanding about the patterns of insurance coverage they experience. This study uses the Census Bureau’s 1993-1996 panel of the Survey of Income and Program Participation to evaluate differences in the duration of, and in their entry into and exit from, uninsured spells. While the average duration of newspells was shorter for rural children and most regained coverage quickly, rural children were also more likely than urban children to experience protracted spells of uninsurance. Moreover, rural children were more likely than urban children to move between public and private coverage. These findings have important implications for designing insurance expansion programs and outreach strategies to effectively enroll and retain rural children.
Human herpesvirus 6 induces interleukin-1 beta and tumor necrosis factor alpha, but not interleukin-6, in peripheral blood mononuclear cell cultures

The human herpesvirus 6 (HHV-6) is known to interact intimately with cells of the immune system. Here we report that HHV-6 is a potent inducer of interleukin-1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF-alpha) in cultures of peripheral blood mononuclear cells. In contradistinction, HHV-6 has no effect on IL-6 synthesis. Maximal IL-1 beta and TNF-alpha gene transcription, as detected by polymerase chain reaction amplification analysis, is observed at 12 and 6 h postinfection, respectively. Release of IL-1 beta and TNF-alpha into the culture supernatants peaked at 24 h and gradually decreased with time. Heat-inactivated virus was unable to stimulate IL-1 beta and TNF-alpha syntheses, whereas UV-irradiated virus retained the full monokine-inducing potential of the native particle. Preincubation of viral preparation with neutralizing anti-HHV-6 antibody resulted in the abrogation of this cytokine-inducing effect, whereas treatment of cells with phosphonoacetic acid (an inhibitor of viral DNA polymerase activity) had no effect on the ability of the virus to stimulate monokine release. These results indicate that HHV-6 can exert a strong immunomodulatory effect by stimulating the cells of myeloid lineage to produce these cytokines.
Monitoring soil erosion in South Africa at a regional scale: review and recommendations

Loss of topsoil is one of the principal soil degradation problems confronting agriculture throughout South Africa and receives special attention by policy-makers. For effective prevention and remediation, the spatial extent of the problem has to be established and monitored. Recent developments in the application of remote sensing and GIS to the study of soil erosion offer considerable potential in this regard. This paper outlines key technologies available for monitoring, and highlights the problems to be solved at a regional scale. The status of the technologies used in South Africa are reviewed and the more recent studies related to soil erosion are presented in a comparative context. Spatial, temporal and measurement variabilities are major constraints in erosion assessment. Previous erosion studies conducted in South Africa at the regional scale have disregarded important erosion factors and have overvalued less important ones. Different processes and interactions are likely to emerge as dominant when crossing scale boundaries. Such considerations highlight the need to establish a methodological framework to guide and standardize future regional soil loss monitoring efforts.
Same-sex attraction disclosure to health care providers among New York City men who have sex with men: implications for HIV testing approaches.

BACKGROUND While the Centers for Disease Control and Prevention recommends at least annual human immunodeficiency virus (HIV) screening for men who have sex with men (MSM), a large number of HIV infections among this population go unrecognized. We examined the association between disclosing to their medical providers (eg, physicians, nurses, physician assistants) same-sex attraction and self-reported HIV testing among MSM in New York City, New York. METHODS All men recruited from the New York City National HIV Behavioral Surveillance (NHBS) project who reported at least 1 male sex partner in the past year and self-reported as HIV seronegative were included in the analysis. The primary outcome of interest was a participant having told his health care provider that he is attracted to or has sex with other men. Sociodemographic and behavioral factors were examined in relation to disclosure of same-sex attraction. RESULTS Among the 452 MSM respondents, 175 (39%) did not disclose to their health care providers. Black and Hispanic MSM (adjusted odds ratios, 0.28 [95% confidence interval, 0.14-0.53] and 0.46 [95% confidence interval, 0.24-0.85], respectively) were less likely than white MSM to have disclosed to their health care providers. No MSM who identified themselves as bisexual had disclosed to their health care providers. Those who had ever been tested for HIV were more likely to have disclosed to their health care providers (adjusted odds ratio, 2.10; 95% confidence interval, 1.01-4.38). CONCLUSIONS These data suggest that risk-based HIV testing, which is contingent on health care providers being aware of their patients' risks, could miss these high-risk persons.
Analyse à granularité fine de la subjectivité

Avec l’essor du web social, les internautes sont davantage enclins a partager et affirmer leurs opinions. Devant l’ampleur du phenomene, les opinions exprimees sur internet sont devenues des donnees strategiques qu’il faut pouvoir suivre en temps reel et caracteriser finement. Notre demarche nous amene a recadrer le terme d’opinion dans les theories linguistiques sur la subjectivite et l’evaluation. Nous nous interessons a delimiter automatiquement les passages subjectifs d’un texte et a en categoriser plusieurs aspects semantiques et enonciatifs : ont-ils une modalite logique ou axiologique ? quelle est leur polarite ? le locuteur dissimule t-il sa subjectivite ? quel est l’objet cible ? Notre premiere contribution pour aborder ces questions consiste en la distribution de deux ressources : le corpus Blogoscopie contient 5 900 passages evaluatifs et 6 900 objets annotes. Il est le premier corpus francophone de ce type ; le lexique de l’evaluation represente 4 000 mots ou expressions evaluatifs du francais structures gramaticalement et semantiquement. A partir de ces ressources, nous proposons des methodes pour resoudre trois problematiques liees a l’analyse de la subjectivite. La premiere methode combine des caracteristiques lexicales, grammaticales et semantiques pour delimiter et desambiguiser les evaluations d’un texte. Puis, nous evaluons deux methodes s’appuyant sur des hypotheses semantiques et morphologiques pour apprendre du vocabulaire evaluatif habituellement absent des ressources existantes. Enfin, nous experimentons une nouvelle methode, fondee sur la saillance d’un objet, ameliorant l’existant sur la tâche d’identification de la cible d’une evaluation.
Elaboração de um modelo tridimensional personalizado de um paciente reabilitado com protocolo inferior - análise em elementos finitos

The present study had the objective of elaborating a customized threedimensional model of a patient rehabilitated with a mandibular protocol. The model was used in the finite element method to evaluate the influence, from a biomechanical point of view, of chewing forces on peri-implant bone remodeling. The use of a computerized tomography of an edentulous jaw allowed the construction of the customized 3D model and the evaluation of the stress distribution. We used stereolithography . STL files, interactive image processing software and Marc / Mentat Finite Element software. The data were analyzed comparatively at predefined points in the model.
Is hepatic resection justified after chemotherapy in patients with colorectal liver metastases and lymph node involvement?

PURPOSE For patients with colorectal liver metastases (CLM), regional lymph node (RLN) involvement is one of the worst prognostic factors. The objective of this study was to evaluate the ability of a multidisciplinary approach, including preoperative chemotherapy and hepatectomy, to improve patient outcomes. PATIENTS AND METHODS Outcomes for a consecutively treated group of patients with CLM and simultaneous RLN involvement were compared with a cohort of patients without RLN involvement. Univariate and multivariate analysis of clinical variables was used to identify prognostic factors in this high-risk group. Results Of the 763 patients who underwent resection at our institution for CLM between 1992 and 2006, 47 patients (6%) were treated with hepatectomy and simultaneous lymphadenectomy. All patients had received preoperative chemotherapy. Five-year overall survival (OS) for patients with and without RLN involvement were 18% and 53%, respectively (P < .001). Five-year disease-free survival rates were 11% and 23%, respectively (P = .004). When diagnosed preoperatively, RLN involvement had an increased 5-year OS compared with intraoperative detection, although the difference was not significant (35% v 10%; P = .18). Location of metastatic RLN strongly influenced survival, with observed 5-year OS of 25% for pedicular, 0% for celiac, and 0% for para-aortic RLN (P = .001). At multivariate analysis, celiac RLN involvement and age >or= 40 years were identified as independent poor prognostic factors. CONCLUSION Combined liver resection and pedicular lymphadenectomy is justified when RLN metastases respond to or are stabilized by preoperative chemotherapy, particularly in young patients. In contrast, this approach does not benefit patients with celiac and/or para-aortic RLN involvement, even when patients' disease is responding to preoperative chemotherapy.
Analysis of loss of heterozygosity in atypical and negative bile duct brushing cytology specimens with malignant outcome: are "false-negative" cytologic findings a representation of morphologically subtle molecular alterations?

CONTEXT Conventional cytologic evaluation of bile duct brushings for neoplasia has high specificity but relatively low sensitivity. OBJECTIVE The aim of this pilot study was to examine whether K-ras mutations and loss of heterozygosity for multiple microsatellite markers in bile duct brushings would contribute to the detection of malignancy in cases initially reported as "negative" or "atypical. " DESIGN Bile duct brushing specimens with a negative or an atypical cytologic result (9 cases) had a benign result on the surgical pathology specimen, and 9 additional negative or atypical cases demonstrated adenocarcinoma on the resected surgical specimen. Cells from representative cytopathology and histology slides were microdissected and analyzed for K-ras mutations and for loss of heterozygosity with a panel of 15 polymorphic markers on chromosomes 1p, 3p, 5q, 9p, 9q, 10q, 17p, and 22q. RESULTS Among cytology cases with malignant outcome, loss of heterozygosity or K-ras mutation was detected in 8 (88.8%) of 9 cases. In the corresponding 9 surgical pathology specimens with adenocarcinoma, K-ras mutations and/or allelic losses were detected in all (100%). Loss of heterozygosity or K-ras mutation was not detected in cytology cases that had a benign surgical outcome. The fractional allelic loss of these 9 cytology specimens ranged from 0 to 0.25 (mean, 0.14). This compared with the fractional allelic loss ranging from 0.15 to 0.42 (mean, 0.27) for the corresponding surgical specimens. CONCLUSIONS This pilot study suggests that low-level fractional allelic loss or K-ras mutation in the negative/atypical cytology samples with malignant outcome is a representation of morphologically subtle molecular alterations.
The Thiamine Kinase (YcfN) Enzyme Plays a Minor but Significant Role in Cobinamide Salvaging in Salmonella enterica

ABSTRACT Cobinamide (Cbi) salvaging is impaired, but not abolished, in a Salmonella enterica strain lacking a functional cobU gene. CobU is a bifunctional enzyme (NTP:adenosylcobinamide [NTP:AdoCbi] kinase, GTP:adenosylcobinamide-phosphate [GTP:AdoCbi-P] guanylyltransferase) whose AdoCbi kinase activity is necessary for Cbi salvaging in this bacterium. Inactivation of the ycfN gene in a ΔcobU strain abrogated Cbi salvaging. Introduction of a plasmid carrying the ycfN+ allele into a ΔcobU ΔycfN strain substantially restored Cbi salvaging. Mass spectrometry data indicate that when YcfN-enriched cell extracts were incubated with AdoCbi and ATP, the product of the reaction was AdoCbi-P. Results from bioassays confirmed that YcfN converted AdoCbi to AdoCbi-P in an ATP-dependent manner. YcfN is a good example of enzymes that are used by the cell in multiple pathways to ensure the salvaging of valuable precursors.
Critical analysis of the integration of residual municipal solid waste incineration and selective collection in two Italian tourist areas

Municipal solid waste management is not only a contemporary problem, but also an issue at world level. In detail, the tourist areas are more difficult to be managed. The dynamics of municipal solid waste production in tourist areas is affected by the addition of a significant amount of population equivalent during a few months. Consequences are seen in terms of the amount of municipal solid waste to be managed, but also on the quality of selective collection. In this article two case studies are analyzed in order to point out some strategies useful for a correct management of this problem, also taking into account the interactions with the sector of waste-to-energy. The case studies concern a tourist area in the north of Italy and another area in the south. Peak production is clearly visible during the year. Selective collection variations demonstrate that the tourists’ behavior is not adequate to get the same results as with the resident population.
