Mazzacchi, Francesco. "Evaluation of the TAU CFD solver for steady and unsteady turbulent flow analysis of a supercritical wing." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2017. http://amslaurea.unibo.it/13370/.
Full textAbstract:
The present work is part of a long-term project aimed at the validation and development of the code in DLR-TAU CFD solver in order to predict the steady and unsteady flow fields, forced and unforced motion and aeroelastic response.
The strategy to validate these methods consists of the identification and quantification of errors in the computational models and the evaluation of the calculation results with the experimental data.
The experimental data were obtained from NASA Langley Transonic Dynamics Tunnel.
The aim is to assess the state-of-the-art Computational Aeroelasticity methods for the prediction of dynamic and static aeroelastic phenomena.
All of this is based on the first and second AIAA Aeroelastic Prediction Workshops, where the (BSCW) Benchmark Supercritical Wing has been chosen as a reference point for these workshops.
The BSCW has a simple geometrical structure, with a rectangular planform and it is considered to be a rigid structure. Three different Test Cases have been determined with different and pre-fixed angles of attack.
The simulations were carried out in the transonic range with Mach numbers between 0.70 $\div$ 0.85 where different flow phenomena may occur and cause serious problems, such as aeroelastic flutter, buffet, and limit cycle oscillations.
The author used the DLR-TAU code implemented by Reynolds-averaged Navier-Stokes (RANS) equations. Several computational setups are implemented and two different types of turbulence models: (SA) Spalart-Allmaras and the (k-$\omega$ SST) Shear Stress Transport.
At the end of this work two different approaches have been compared; the RANS simulations from DLR-Tau and the hybrid from SU2. The latter was carried out by another participant. Both approaches can resolve the largest turbulent structures, but only the hybrid approach can provide significant solutions.

El marco general de esta tesis ha sido el Proyecto EDUTODOS: Progresos y limitaciones de la Educación para Todos: la política de la agenda educativa, la tendencia de las desigualdades educativas y la calidad de la democracia en América Latina, del Grupo Interdisciplinar sobre Políticas Educativas de la Universidad Autónoma de Barcelona y la Universidad de Barcelona. Específicamente, se estudió la relación entre el primero de los Objetivos de la Educación Para Todos, la Atención y Educación para la Primera Infancia (AEPI) y la reducción de las desigualdades sociales en México. Actualmente, la Educación Inicial No Escolarizada (EINE) es la principal estrategia de AEPI aplicada en ese país. El objetivo general del trabajo fue elaborar un perfil de indicadores de buenas prácticas en AEPI en contextos de desigualdad social en el Estado de Puebla, México. A partir de la revisión de la bibliografía más relevante en la temática, se describió el estado actual de la AEPI en el mundo y su relación con la disminución de las desigualdades sociales. Se elaboró una propuesta de indicadores de AEPI en contextos de desigualdad social que se denominó Modelo de Indicadores de Buenas Prácticas en Atención y Educación Para la Primera Infancia (MIBP-AEPI). Finalmente, a partir de la propuesta de indicadores, y como resultado del trabajo de campo, se detectaron factores comunes en experiencias de buenas prácticas de AEPI en Puebla y se elaboró un perfil de indicadores de buenas prácticas en AEPI en contextos de desigualdad social. Se concluye que las buenas prácticas estudiadas se insertan en contextos caracterizados por las desigualdades en los ámbitos demográficos, económicos y socioculturales, y que algunas de estas desigualdades son compensadas por las buenas prácticas del programa de EINE.The general framework of this thesis was the EDUTODOS Project. Progress and limitations of the Education for All: policy of educational agenda, the trend of educational inequalities, and the quality of democracy in Latin America, of the Interdisciplinary Group on Educational Policy (Autonomous University of Barcelona and University of Barcelona). Specifically, it was studied the relationship among the first of the Objectives of Education For All, the Early Childhood Care and Education (ECCE), and the reduction of social inequalities in Mexico. Currently, the Non-schooled Initial Education (NSIE) is the main ECCE strategy applied in that country. The aim of this research was to develop a profile of indicators of good practice in ECCE in contexts of social inequality in the State of Puebla, Mexico. After reviewing the most relevant literature on the subject, it was described the status of ECCE in the world and its relationship with the reduction of social inequalities. It was developed a proposal of indicators of ECCE in contexts of social inequality that was called Model of Indicators of Good Practice in Early Childhood Care and Education. Finally, based on the proposed indicators, and as a result of the fieldwork, common factors were found in experiences of good practice in ECCE in Puebla and it was developed a profile of indicators of good practice in ECCE in contexts of social inequality. It was concluded that good practices are embedded in contexts characterized by inequalities in demographic, economic and socio-cultural areas, and that some of these inequalities are compensated by the good practices of the NSIE program.

Full textAbstract:
Previously, social movement theory has focused on constructs of identity, such as race/ethnicity, gender and sexual preference, for collective identity construction. Prochansky (1983:59) introduces the concept of place identity, situating it along with the other components of identity, such as the ones mentioned above. In addition, literature on Appalachia has shown land to be an important construct of Appalachian peoples identity. This paper analyzes, through content analysis, the collective identities of writers who wrote letters to the U.S. Forest Service in opposition to a proposed AEP power line. This power line was to run through lands in Appalachia, such as various private properties, the Jefferson and George Washington National Forests, and across the New River. Collective identities based on place-identity, specifically including land, were the main target of analysis, due to the importance of land for Appalachian people. This analysis suggests that land, as a type of place identity, does serve as a basis for collective identity.Master of Science

Introduction. For hardware used in radar systems of today, technology is evolving in an increasing rate. For existing software in radar systems, relying on specific drivers or hardware, this quickly becomes a problem. When hardware required is no longer produced or outdated, compatibility problems emerges between the new hardware and existing software. This research will focus on exploring if the virtualization technology can be helpful in solving this problem. Would it be possible to address the compatibility problem with the help of hypervisor solutions, while also maintaining high performance? Objectives. The aim with this research is to explore the virtualization technology with focus on hypervisors, to improve the way that hardware and software cooperate within a radar system. The research will investigate if it is possible to solve compatibility problems between new hardware and already existing software, while also analysing the performance of virtual solutions compared to non-virtualized. Methods. The proposed method is an experiment were the two hypervisors Xen and KVM will analysed. The hypervisors will be running on two different systems. A native environment with similarities to a radar system will be built and then compared with the same system, but now with hypervisor solutions applied. Research around the area of virtualization will be conducted with focus on security, hypervisor features and compatibility. Results. The results will present a proposed virtual environment setup with the hypervisors installed. To address the compatibility issue, an old operating system has been used to prove that implemented virtualization works. Finally performance results are presented for the native environment compared against a virtual environment. Conclusions. From results gathered with benchmarks, we can see that the individual performance might vary, which is to be expected when used on different hardware. A virtual setup has been built, including Xen and KVM hypervisors, together with NAS communication. Running an old operating system as a virtual guest, compatibility has been proven to exist between software and hardware using KVM as the virtual solution. From the results gathered, KVM seems like a good solution to investigate more.

Full textAbstract:
Based on data from 2083 wind turbines installed in Sweden since 1988, the annual energy production (AEP) predictions considered at the project planning phases of the wind turbines in Sweden have been compared to the wind-index-corrected production data. The production data and the predicted AEP data are taken from Vindstat, a database that collects information directly from wind turbine owners in Sweden. The mean error for all analyzed wind turbines was 11.9%,which means that, overall, the predicted AEP has been overestimated. There has been improved accuracy with time and error in prediction decreasing from 12% to 6.3% for wind turbines installed in the 2000s and 2010s, respectively. However, the overall improvement in accuracy seems to have stagnated around 2005 despite the refinement of forecasting methods and better data availability. From the results analyzed for effects of terrain, the error is smaller for wind turbines in forest areas than in open terrain, indicating that the complexity of forest terrain is not the reason behind the error. Also, there is no apparent increase of error with wind farm size, which could have been expected if the wind farm blockage effect was a primary reason for the overestimations. Comparison between significant wind turbine manufacturers Vestas and Enercon in the Swedish context, the error was more prominent for Enercon.

Taiby, Awrang. "WIDEBAND, LOW-LOSS, HIGH-POWER HANDLING DIPLEXER FOR AIRBORNE EARLY WARNING (AEW) SYSTEMS." DigitalCommons@CalPoly, 2012. https://digitalcommons.calpoly.edu/theses/745.
Full textAbstract:
Airborne Early Warning (AEW) systems rely on rotary couplers (RC) to interface rotating antenna elements on aircraft exteriors with stationary onboard systems. The demand for additional channels in new generation AEW systems increases the complexity of rotary couplers significantly. On the other hand, if signals in separate frequency bands use the same channel, existing AEW designs could incorporate additional channels with only minor changes. Passive RF diplexers can accomplish this task. Required characteristics include low-loss (<0.5dB), wideband (4.4:1), and high-power (>6kW) handling capability. Two diplexer candidates are synthesized and characterized with the aid of a commercial circuit simulation package that includes a 3D full-wave EM solver. A semi-lumped coaxial and a digital elliptic diplexer are proposed, both of which have theoretically low-loss and acceptable VSWR characteristics. However, only the latter diplexer meets operating requirements without the excessive tuning or analysis required by the former. Further studies of the semi-lumped diplexer characteristics may make it useful in other applications.
This thesis defines diplexer design goals, provides a brief introduction to filter theory, and compares performance characteristics of the semi-lumped and digital elliptic diplexers. Simulation results for both designs demonstrate that the digital elliptic diplexer is an optimum solution.

Full textAbstract:
Près de 25% de la population mondiale est alimentée par de l’eau en provenance d’aquifères karstiques. La compréhension et la protection de ces derniers apparait donc comme essentielle dans le cadre d’une augmentation des besoins en eau potable. De plus, une contamination des forages d'alimentation en eau potable par une eau turbide peut s'avérer fortement dommageable car entrainant une possible contamination des populations desservies. Dans le cas de la Normandie, des coupures régulières son nécessaires afin de préserver la santé des habitants. La modélisation et la prédiction des augmentations de turbidité apparaissent comme un travail difficile du fait des nombreux phénomènes et paramètres régissant la turbidité ainsi que la non-linéarité de la réponse entre les précipitations et la turbidité. Peu de modèles à l'heure actuelle ont été proposés pour représenter la relation liant la turbidité avec les précipitations. C'est ainsi, en s'intéressant au forage AEP d'Yport responsable de l'alimentation en eau potable de la ville du Havre, que nous proposons une application des réseaux de neurones pour la prévision de la turbidité. Durant les travaux de thèse, nous avons mis en avant la nécessité d'effectuer des campagnes d'échantillonnages des produits phytosanitaires afin de permettre l'identification des éventuels proxies des produits phytosanitaires tel que la turbidité, les précipitations ou bien la conductivité. Par la suite, les travaux effectués dans cette thèse nous ont permis (i) de monter que les modèles par réseaux de neurones permettent de prévoir à 12h et 24h les variations de turbidité, (ii) de tester plusieurs voies d'amélioration de ces modèles, (iii) d'intégrer l'analyse multirésolution aux modèles par réseaux de neurones et pour finir (iiii) d'identifier un semi proxy des contaminations en produits phytosanitairesApproximately 25% of the world's population is supplied by water from karstic aquifers. The understanding and protection of these appears to be essential in the context of drinking water needs increasing. In addition, contamination of drinking water by turbid water can be highly damaging by resulting in possible contamination of the served populations. In the case of Normandy, regular drinking water cut-off are necessary to preserve the health of the inhabitants. The modeling and prediction of turbidity event appears as a challenging work because of the number of phenomenon and parameters involves in turbidity variation as well as the non-linearity of the link between rainfall and turbidity. Actually, few models have been proposed to represent the relationship between turbidity and rainfall. In this context, by focusing on Yport's pumping well which is responsible for Half of Le Havre city drinking water supply, we propose an application of neural networks for turbidity prediction. During this thesis work, we emphasized the need to carry out sampling campaigns for phytosanitary products to enable the identification of possible phytosanitary product proxies such as turbidity, rainfall or conductivity. Subsequently, the work carried out in this thesis enabled us to (i) designed neural network models allow to predict at 12h and 24h the turbidity variations, (ii) test several ways to improve these models, (iii) integrate multiresolution analysis into neural networks models and finally (iiii) identify a semi proxy for phytosanitary product contamination

Resumo: A presente dissertação propõe-se a realizar uma meta-avaliação de uma das linhas de avaliação instituídas pela Controladoria-Geral da União - CGU/PR, intitulada Avaliação da Execução de Programas de Governo - AEPG, utilizando como estudo de caso a avaliação do Programa Estratégia da Saúde da Família (ESF). A pesquisa teve como objetivos específicos: a) identificação e avaliação dos critérios que ensejaram a seleção do Programa para realização da AEPG; b) verificação e discussão quanto aos critérios seletivos estabelecidos para indicação da amostra dos municípios para realização da AEPG, verificando a objetividade dos parâmetros e a proporcionalidade da distribuição nacional, regional e estadual; c) a partir do cotejamento das questões estratégicas estabelecidas para a fiscalização, determinar a aptidão da AEPG para identificar desajustes que importem na melhoria estruturante do ESF; e d) considerando as providências adotadas pelos gestores federais diante das impropriedades e irregularidades consignadas no Relatório de Avaliação - Rav, aferir a resolutividade resultante da AEPG no ESF. A meta-avaliação sobre a AEPG do ESF demonstrou que: i) a designação do Programa ESF para a realização da avaliação efetivamente se deu mediante hierarquização, a partir de critérios objetivos, no caso, materialidade, relevância e criticidade; ii) não foi utilizada inferência estatística objetiva na definição dos municípios fiscalizados, utilizando-se como parâmetro a disponibilidade de servidores da CGU/PR em cada um dos Estados da Federação; iii) as questões estratégicas definidas para verificação na AEPG do ESF pela CGU atuaram sobre pontos estratégicos da política pública; iv) as medidas e providências adotadas pelo Ministério da Saúde em questões estruturantes da referida ação governamental importaram no incremento da efetividade da referida política pública. Por outro lado, constatou-se prejuízos no tocante ao potencial gerencial dos diagnósticos apresentados e omissão de dados e informações que comprometeram a transparência da avaliação. Palavras-chave: Meta-avaliação. Estratégia de Saúde da Família - ESF. Controladoria-Geral da União - CGU/PR. Avaliação da Execução de Programas de Governo - AEPG. Avaliação de resultados e impactos.
Abstract: The present dissertation proposes to conduct a meta-evaluation of one of the evaluation lines instituted by the General Union Controller - CGU / PR, entitled Evaluation of Government Programs Execution - AEPG, having as a case study the evaluation of the Family Health Strategy Program (ESF). The research has as specific objectives: a) identification and evaluation of the criteria that led to select the Program ESF as evaluating target of the AEPG; b) verification and discussion regarding the selective criteria established to compose the sample of municipalities for the realization of AEPG, verifying the objectivity of the parameters and the proportionality of the national, regional and state distribution; c) from the comparison of strategic issues established for the inspection, one intended to determine the ability of the AEPG to identify mismatches that affect the structural improvement of the ESF Program; and d) considering the measures taken by the federal managers in face of the improprieties and irregularities recorded in the Evaluation Report - Rav, it was conducted an assessment of the resolution resulting from the AEPG regarding the ESF Program. The ESF meta-evaluation demonstrated that: i) the designation of the ESF Program to carry out the evaluation was effectively based on objective criteria, like materiality, relevance and criticality; ii) no objective statistical inference was used in the definition of the municipalities inspected, using as a parameter the availability of CGU / PR servers in each of the States of the Federation; iii) the issues defined for verification in the AEPG of the ESF Program by the CGU acted on strategic points of public policy; iv) the measures and arrangements adopted by the Ministry of Health have contributed to increase the effectiveness of the ESF policy. On the other hand, there were losses regarding the managerial potential of the diagnoses presented by the AEPG and resulting from the omission of data and information that compromised the transparency of the evaluation. Keywords: Metaevaluation. Family Health Strategy Program - ESF. General Union Controller - CGU/PR. Evaluation of the Execution of Government Programs - AEPG. Evaluation of results and impacts.

Full textAbstract:
The research aimed to increase understanding of the adverse life experiences young people attending AEP have been exposed to. The impact of exposure was captured quantitatively - in relation to PTSD and related symptoms scores ~ and qualitatively by accessing Pupil Voice through semi~structured interviews. Sample: The original sample screened comprised 45 young people (25 males; 20 females) attending AEP. The mean age of participants was 15.82 years. Method: Screening measures were employed to identify young people who had been exposed to potentially traumatic events and whether or not they had been affected by this exposure. A subsample of participants were identified and interviewed in relation to the impact of exposure to trauma. Results: Adolescents in AEP settings have been exposed to a wide range of adverse events and have been significantly impacted as a result. Cognisance was taken of Northern Ireland's post~conflict status in an effort to contextualise the results. Conclusion: Adverse life events can have a widespread impact on the lives of young people, extending beyond clinical levels of PTSD and related disorders. School based educators and professionals are well placed to provide support to trauma exposed youth. Support efforts must holistically consider the wider impact of trauma and its manifestations both within and outside the learning environment

Fundamento: Los servicios de urgencia constituyen una de las principales puertas de acceso al sistema sanitario. La preocupación por el aumento de la demanda urgente y por su uso indiscriminado, estimula la necesidad de revisar la utilización y organizar áreas alternativas a la hospitalización convencional.Objetivo: Evaluar la aplicabilidad específica de los procedimientos de revisión de la utilización en la atención de las urgencias. Diseñar un protocolo AEP adaptado a las áreas de observación de urgencias (AOSU). Cuantificar el porcentaje de admisión y estancias inadecuadas, identificando sus motivos, y las variables que se encuentran asociadas.
Material y método: Diseño de un protocolo adaptado con mínimas modificaciones del AEP original. Se analizó la concordancia en la utilización del instrumento intra e interobservadores que obtuvo índices de kappa del 0,80 y 0,68, respectivamente. Tras un análisis descriptivo, se utilizó el paquete estadístico SPSS que permitió un análisis bivariante, cálculo de odds ratio y análisis de regresión logística múltiple.
Resultados: Estudio concurrente de 4.700 pacientes ingresados consecutivamente en AOSU del Hospital Mútua de Terrassa (Barcelona) durante 18 meses. El 55% de los pacientes eran hombres y la edad media global 63,9 años (+/-20,0). Ingresaron para observación de Medicina (78,5%), Cirugía (11%) y Trauma (9%). La estancia media global fue 29,3 horas (+/-17,5), siendo el 35,5% de las altas a domicilio, y el 62% de los pacientes ingresaron. La proporción de ingresos inadecuados en AOSU representó el 5,5% de las admisiones, debido principalmente al acceso directo del paciente a urgencias, priorización de pruebas y atención que podía prestarse a nivel ambulatorio. Las variables independientes significativamente asociadas con una mayor probabilidad de admisión inadecuada han sido la estación del año (verano, primavera y otoño), presión de urgencias <85%, complejidad de la patología <0,6 (según GRD) y sexo mujer. La proporción de estancias inadecuadas fue del 16,9%, motivadas principalmente por déficit de camas hospitalarias convencionales para el adecuado drenaje de pacientes. Se asoció a la edad >64 años, estación (otoño e invierno), duración de la estancia >24 horas, ingreso hospitalario al alta de AOSU, complejidad >0,6, especialidad de medicina y admisión inadecuada previa.
Conclusiones: La utilización de un servicio de urgencias se ve influenciado por características del enfermo (edad, sexo, complejidad), el modelo organizativo y de gestión (especialidad, estancia, presión de urgencias) además de factores ambientales (estacionalidad, día de la semana, horario) y puede optimizarse si se potencia el funcionamiento protocolizado de áreas de observación previos a la admisión definitiva. La monitorización periódica de la adecuación ha de ser un componente esencial del Plan de Calidad de los centros.

Full textAbstract:
Les relations commerciales entre l’Union européenne (UE) et les Etats d’Afrique, des Caraïbes et du Pacifique (ACP) ont longtemps été caractérisées par un régime préférentiel non réciproque. Ce régime a finalement été dénoncé en raison de son incompatibilité avec les règles de l’Organisation mondiale du commerce (OMC). Pour se mettre en conformité avec les exigences de l’OMC, l’UE a voulu que ses relations commerciales avec les Etats ACP soient désormais régies par des Accords de partenariat économique (APE) qui doivent être négocié avec les groupements régionaux ACP. Après plus de 12 ans de négociations, les pays de la Communauté économique des États de l'Afrique de l'Ouest (CEDEAO) ont signé les APE avec l’UE ; sur fond de controverses quant aux réels bénéfices attendus d’un tel accord. Aussi, notre thèse s’est proposée de réévaluer l’impact (en termes de création ou de détournement de commerce) des APE sur les économies des pays de l’Afrique de l’Ouest, et plus particulièrement le Burkina Faso. Cette étude est basée sur un modèle d’équilibre général calculable (MEGC) construit à partir du modèle PEP-1t de Decaluwé et al. (2013) et calibré avec la Matrice de Comptabilité sociale (MCS) du Burkina version 2012. Nos résultats montrent que les APE donnent un avantage compétitif à l’UE avec des effets de détournement de commerce qui se traduisent par une augmentation des importations en provenance de l’UE, ce qui contraste avec l’absence d’un effet d’accroissement réel des exportations du Burkina Faso vers l’UE et la CEDEAO. Toutefois, les APE améliorent sensiblement le bien-être des populations, mais ne permet pas de réduire la pauvreté et les inégalitésEconomic relations between the European Union (EU) and the African, Caribbean and Pacific Group of States (ACP) have been characterized by non-reciprocal preferential trade agreements. These trade agreements have been continuously criticized for being incompatible with WTO rules. In order to conform to the norms of international trade, the EU has required that its economic relations with the ACP states are governed by the Economic Partnership Agreements (EPA), which are negotiated with three African Regional Economic Communities. After more than twelve years of negotiations, the countries of the Economic Community of West African States (ECOWAS) have signed the EPA with the EU, despite differing opinions on the real benefits that can be expected from such agreements. The aim of this thesis is to evaluate the impact of the EPA on the economies of the ECOWAS (in terms of trade creation and diversion), in particular Burkina Faso. The study uses a modified version of the computable general equilibrium model developed in Decaluwé et al. (2013). The static baseline model is calibrated using a social accounting matrix (SAM) for Burkina Faso’s economy of 2012. Our results show that the APE give the EU a competitive advantage. Burkina Faso’s imports originating from the EU increase, manifesting trade diversion. The trade agreements have no significant effect on Burkina Faso’s exports to the EU or the ECOWAS. Furthermore, while the APE considerably improve population well-being, they do not lower poverty or social inequalities

Full textAbstract:
As we move into the twenty-first century, the renewal of our lifelines or deterioration of infrastructure becomes a topic of critical importance. The structures may have to carry larger loads, require change in building use, suffer steel corrosion problems, or errors made during the design or construction phases so that the structure may need to be repaired or strengthened before it can be used. The use of fiber reinforced polymers (FRP) in the last few years in various engineering application, forums and configuration offers an alternative design approach for the construction of new concrete structures and the rehabilitation of existing ones. The use of FRP materials for external strengthening of reinforced concrete (RC) structures has emerged as one of the most exciting and promising technologies in material and structural engineering. Externally bonded FRP reinforcement is relatively unprotected against impact, vandalism or severe environmental conditions. Their structural performance can be greatly affected by these drawbacks. But if the composite material is placed in slots inside the concrete cover some of these drawbacks can be overcome. This method is designated by Near Surface Mounted (NSM) method. Therefore, the presented work is carried out using this advantageous strengthening technique utilizing the non-corrodible FRP materials. My research involved both experimental and analytical investigations on the use of FRP systems for strengthening concrete structures using NSM techniques. The main objectives of my research were to (1) develop/utilize an NSM system composed of FRP bars and adhesives, (2) investigate the bond performance for the proposed NSM system, (3) investigate the effect of freeze and thaw cycles on the of the new proposed system, (4) study the flexural behaviour of RC beams strengthened with NSM FRP bars, (5) develop an analytical model using non-linear finite element analysis (ADINA) taking into consideration the interfacial behaviour between the concrete and FRP bars and (6) establish design recommendations for the use of FRP bars for the NSM method. To achieve these objectives, the research program was divided into two parts. The first part included the experimental work while the second part included the analytical work. The first part consisted of two phases. The first phase included the pullout testing of 76 C-shape concrete blocks including 16 conditioned blocks. The second phase included testing 20 flexural strengthened concrete beams using the NSM method. The second part included developing an analytical model to be used in a non-linear finite element program and to analyze and predict the behaviour of concrete beams strengthened for flexure using NSM FRP bars. The efficiency and accuracy of the model was verified by comparing its results to the experimental results. The developed analytical model was used to study the effect of different parameters. Test results are presented in terms of deflection, strain in the concrete, steel and FRP and modes of failure. Test results showed the superior performance of the proposed NSM FRP/adhesive system. The NSM system is able to increase both the stiffness and flexural capacity of concrete beams by approximately 100% over the unstrengthened one. The FEM was able to predict of the behaviour of the strengthened beams in flexure with NSM. Based on the experimental and analytical study, useful conclusions and recommendations for flexural strengthening with NSM FRP were provided.||Alors que nous entrons dans le XXIème siècle, la dégradation des infrastructures devient un sujet d'une importance cruciale. Les structures doivent supporter des charges plus grandes et subir des changements d'utilisation. En plus de cela s'ajoute les problèmes de corrosion de l'acier, des erreurs de conception et de construction, ce qui souvent nécessitent que la structure soit réparée ou renforcée, des fois même avant sa mise en service. L'utilisation de polymères renforcés de fibres (PRF) dans les dernières années dans divers domaines d'ingénierie a permis une avancée technologique, et leur utilisation dans la construction de nouvelles structures en béton ainsi que la réhabilitation des anciennes. L'utilisation de matériaux en PRF pour le renforcement externe des structures en béton armé est une technologie des plus prometteuses dans l'ingénierie structurale ou de matériaux. Cependant le renforcement par collage externe de PRF n'offre pas une bonne protection contre les chocs, le vandalisme ou les conditions environnementales sévères, ce qui pourraient affecter les performances structurales des éléments réhabilités. Ces inconvénients peuvent être surmontés si le PRF est inséré dans des rainures réalisées dans le recouvrement de béton. Cette méthode est appelée « mise en place d'Armatures Encastrées Près de la surface (AEPS)». Le présent travail s'articule autours de cette technique de renforcement utilisant des matériaux non corrodables. Mes travaux de recherches se focalisent sur l'utilisation des AEPS en PRF pour le renforcement des structures, et cela d'un point de vue expérimental et analytique. Les principaux objectifs de mes recherches sont: (1) développer/utiliser un système d'AEPS composé de barres en PRF et d'adhésif, (2) étudier les performance d'adhérence du système proposé, (3) étudier l'effet des cycles gel-dégel sur le système proposé, (4) l'étude du comportement en flexion de poutres en béton armé, renforcées avec des barres d'AEPS en PRF, (5) développer un modèle analytique utilisant des méthodes non-linéaires d'analyse par éléments finis (logiciel ADINA) en tenant compte du comportement de l'interface béton-barres en PRF, et (6) mettre en place des recommandations de calcul pour l'utilisation des barres en PRF comme AEPS. Pour atteindre ces objectifs, le programme de recherche a été divisé en deux parties. La première partie comprenait les travaux expérimentaux tandis que la deuxième comprenait des travaux d'analyse. La première partie elle même était constituée de deux phases. La première phase comprenait des essais d'arrachement direct de blocs de béton en forme de «C», dont 16 blocs conditionnés dans une chambre environnementale. Alors que la deuxième phase comportait des essais de flexion 20 poutres en béton armé, renforcés par des AEPS en PRF. La deuxième partie a consisté au développement d'un modèle analytique non-linéaire par éléments finis de façon à pouvoir analyser et prédire le comportement en flexion de poutres en béton armé, renforcées par des AEPS en PRF. L'efficacité et la précision du modèle ont été vérifiées en comparant ses résultats analytiques aux résultats expérimentaux. Le modèle analytique développé a été utilisé pour étudier l'effet de différents paramètres. Les résultats des tests sont présentés en termes de déflexion, de contraintes dans le béton, l'acier et le PRF et les modes de rupture. Les résultats des essais ont démontré les bonnes performances du système armatures PRF/adhésif proposé, ce dernier a permit d'augmenter à la fois la rigidité en flexion et la résistance des poutres en béton d'environ 100% par rapport à la poutre non renforcée. L'analyse par éléments finis a été en mesure de prédire le comportement en flexion des poutres renforcées avec des AEPS en PRF. Basé sur ces travaux, des conclusions et des recommandations utiles concernant le renforcement en flexion avec des AEPS en PRF ont été fournis.

Full textAbstract:
In considering methods of reducing the emission of carbon dioxide; there is a growing interest for use of wind power at domestic building in U.K. But the technology of wind turbines development in building environment is more complicated than in open areas. Small wind turbines in suburban areas have been reported as having unsatisfactory energy output, but it is not clear whether this is due to insufficient wind resource or low turbine efficiency. The aim of this research is to discover whether the wind resource in suburban areas is large enough for small wind turbines to produce a useful energy output.Historical wind data and manufacturers' turbine characteristics were used to estimate the hourly wind speed and energy output for different U.K. cities, terrain zones and turbines. It was found that for turbines at 10 m height in suburban areas and depending on city, the annual wind energy conversion efficiency ranged from about 20 to 40%, while the number of turbines required to produce the annual average electricity consumption of a UK dwelling ranged from about 6 for the smallest turbine (5.3 m² rotor area) to about 1 for the largest (35.26 m² rotor area).This analysis was based on average conditions, but the wind speed near buildings can vary considerably from one point to another. In order to predict the performance of wind turbines more accurately, the atmospheric boundary layer (ABL) of suburban areas was simulated in both CFD and wind tunnel models, and models of groups of semi-detached and terraced houses were set in this ABL. It was found that at 10 m height in the area of the houses, the turbulence intensity was too high for satisfactory operation of wind turbines (19 to 35%) while the mean velocity at different points ranged from 86 to 108% of the 10m reference velocity. At 30m height the turbulence intensity was satisfactory (less than 19 %), while the mean velocity ranged from 92 to 103 % of the 30 m reference velocity. It is concluded that for wind turbines in suburban areas, at 10 m height the wind speed is too low and the turbulence is too high for satisfactory performance, while at 30 m height the wind speed is much higher and the turbulence is low enough.

Full textAbstract:
The overarching research problem for this study was the need to improve
upon rational models of policy analysis and delivery, to suit complex postmodern
implementation environments. A theoretical model suited to implementing and
evaluating major education reform initiatives was devised. Called the 'Multiple Discourse Model', it was grounded in systems theory, containing elements
reminiscent of social systems, organisational and structural functionalist research,
especially that of Hoy and Miskel (1982)1. However the model was also designed
to incorporate a parallel naturalistic analysis reminiscent of postmodern critical
pragmatic approaches, such as those explored by Cherryholmes (1994)2. Over a
period of five years, this model was developed through an evaluation of the
implementation of the National Aboriginal and Torres Strait Islander Education Policy (AEP) in the Australian Capital Territory government secondary schools
sector.
The distinguishing feature of the study's methodology was its multiperspective
analysis, an approach suggested by Mclaughlin (1987)3 to take account
of the differing communities of discourse which exist in a reformist policy
implementation environment.
To operationalise the research problem, dimensions of policy effectiveness
were articulated. These were addressed through a comprehensive set of research
indicators, extracted from the AEP's national policy goals and the local strategic and
operational plans. Data aimed at judging the effectiveness of implementation were
collected from multiple sources using multiple research instruments. These data
were analysed in three stages using a purpose-designed computer program which
could cross-reference between the four interacting dimensions of research
indicators, research instruments, data sources, and potential variables modifying
policy/program outcomes.
It was found that this model produced clear conclusions about the
effectiveness of AEP implementation in the delimited sector, within the framework
of the AEP's own policy assumptions. The model also provided insights into critical
issues which are generalisable to the national context, such as the power of cultural
hegemony and the socio-political predicament of Aboriginal and Torres Strait
Islander dispossession. As a methodology, the model was found to have a number
of technical advantages, including its capacity for focussing on selected areas of the
implementation environment, its provision of access to multiple levels of detail
amongst data and its possession of mechanisms for monitoring its own internal
validity.
The evaluation case study, used as the vehicle for the Multiple Discourse
Model's development, demonstrated that best-practice administration was in place
which enhanced short and medium-term policy/program outcomes. However, the
study's findings also suggested that a fundamental disjuncture existed between the
AEP's policy/administration paradigm and the conflicting assumptions of the primary
target communities, reinforcing the findings of Sykes (1986)4. The research results
suggested that despite measurable successful inputs, the planned long-term
outcomes of the AEP will not necessarily be achieved. No significant administrative
structures or actions were apparent which could resolve this lack of synchrony at the
interface between government delivery systems and 'grass roots' Aboriginal and
Torres Strait Islander community values. This raised doubts about whether any
systems approach, however well refined, could be socially useful not only for
evaluation, but also as a basis for reform policy and public administration in a
postmodern pluralist democratic setting. The evaluation was therefore used as a
locus for theoretical reflection as well.
A new policy paradigm is suggested, based on a power-sharing 'theory of
community', more in keeping with Aboriginal and Torres Strait Islander peoples'
aspirations for self determination and more likely to alleviate the so far unresolved
destructive effects of cultural and political dispossession.

Full textAbstract:
This project is conducted in cooperation with Hexicon AB, which is a Swedish design and engineering company developing floating two-turbine platforms for offshore wind power.The study aims to investigate the optimal placement of Hexicon AB’s platforms in an offshore wind farm with respect to the Annual Energy Production (AEP). Wind farm layout optimization is a complex problem and it has been approached by the development of calculation and optimization programs in Matlab. The analytical Jensen wake model has been utilized for calculation of AEP and important inputs to the program have been turbine parameters and site specific conditions. The optimization strategy used is a multi-stage algorithm where the gradient-based local search algorithm Fmincon has been used in combination with a version of the heuristic genetic algorithm. The developed programs have been tested and evaluated through a case study. Included in the case study is also a brief financial evaluation regarding how different scenarios in electricity export price and costs for cabling could affect the feasibility of the optimized layouts. Concluded from the project is that the developed programs can be used to investigate the optimal placement of floating two-turbine platforms with respect to AEP. In the case study it was found that the optimized layout obtained a wind farm efficiency of around 4% more than for the conventional staggered layout that was tested. What is also emphasized is that the feasibility of the optimized layouts obtained from the program is quite sensitive toward changes in future electricity export price and costs for cabling and installation. Hence, it is important to perform a careful financial analysis in order to draw conclusions regarding what layout is the better option for a specific situation.Dagens utbyggnad av vindkraft sker i allt större utsträckning genom etablering av vindkraftparker. De främsta fördelarna med att placera vindkraftverken i parker är att de höga fasta kostnaderna fördelas på flera kraftverk samt att man kan beställa ett flertal enheter samtidigt och därigenom minska kostnaden per installerad Megawatt (MW). För att ytterligare kunna öka vinsten på investeringen är det viktigt att undersöka optimal inbördes placering av vindkraftverken för att erhålla en så hög energiproduktion som möjligt. Det finns många studier gjorda inom området och ett flertal programvaror utvecklade. Dock finns det endast ett fåtal studier som har inriktat sig specifikt på flytande vindkraftverk. Detta arbete är utfört i samarbete med Hexicon AB, vilket är ett Stockholmsbaserat ingenjörsföretag som utvecklar en patenterad teknik för plattformar avsedda för flytande vindkraft. Det unika med Hexicon ABs patenterade teknik är att två vindkraftverk är placerade på en gemensam plattform. Denna teknik gör det möjligt för plattformen att anpassa sig till vindriktningen vilket ger en ökning av kraftverkens energiutbyte. Då det inte finns några utvecklade optimeringsmetoder för flytande plattformar som kan anpassa sig efter vindriktning är syftet för denna studie att undersöka den optimala inbördes placeringen av Hexicon ABs plattformar i en vindkraftpark. Eftersom vindkraftsoptimering är ett komplicerat problem som bland annat är icke-linjärt och icke-konvext så finns det ingen exakt lösning tillgänglig för problemet. Komplexiteten gör även många förenklingar och antaganden nödvändiga för att kunna bearbeta problemet. I detta projekt har sambandet mellan årlig elproduktion och inbördes placering av plattformarna undersökts genom att ett kalkylerings- och optimeringsprogram utvecklats i programvaran Matlab. För att kunna undersöka den optimala inbördes placeringen av vindkraftverken är det viktigt att förstå hur vindkraftverken påverkas av att placeras tillsammans i en park. För att göra detta så behövs en modell för att beskriva den så kallade vaken som uppstår bakom respektive vindkraftverk. Detta gjordes genom att använda den analytiska Jensen vakmodellen, vilket är den vanligaste modellen att använda för optimeringssyften. Beräkningen av elproduktion gjordes baserat på given information angående turbinparametrar samt specifika förhållanden på platsen för vindparken. För det utvecklade optimeringsprogrammet användes en tvåstegsalgoritm där den gradientbaserade algoritmen Fmincon utgjorde den centrala delen. Fmincon är en effektiv algoritm för lokal optimering som finns tillgänglig i Matlab. För att generera bra startgissningar till den lokala optimeringen användes en version av en heuristisk genetisk algoritm som komplement till Fmincon. Denna algoritm bygger på samma princip som processen för naturligt urval i evolutionssammanhang där de bäst lämpade individerna för vidare sina egenskaper till nästa generation. För att ytterligare förbättra algoritmen kompletterades den även med ett moment av slumpmässighet. För att testa och utvärdera de utvecklade programmen genomfördes en fallstudie. I denna studie optimerades 50 stycken olika heuristiska startgissningar. De 20 bäst presterande konfigurationerna valdes ut för vidare analys där de blev utvärderade med avseende på olika scenarion för elpris samt kostnad för elektrisk infrastruktur. Detta för att undersöka hur den optima placeringen eventuellt skulle kunna påverkas av osäkerheter i dessa faktorer. Den genomförda fallstudien indikerade att de utvecklade programmen kan användas för att undersöka den inbördes optimala placeringen av vindkraftverk med avseende på elproduktion. Den ekonomiska utvärderingen indikerade även att den optimala placeringen var känslig för olika scenarion där elpris och kostnader för infrastruktur varierades och att detta kunde påverka lönsamheten för investeringen. Det ska därför betonas att det anses vara viktigt att utföra en mer noggrann ekonomisk utvärdering av de optimerade konfigurationerna för att undersöka vilken positionering som är mest lämplig för en viss situation.

Greenhow, Danielle. "Hearing and Echolocation in Stranded and Captive Odontocete Cetaceans." Scholar Commons, 2013. http://scholarcommons.usf.edu/etd/4682.
Full textAbstract:
Odontocetes use echolocation to detect, track, and discriminate their prey, as well as negotiate their environment. Their hearing abilities match the frequency of greatest sensitivity to the higher frequencies used for foraging and navigation. Hearing and echolocation together provide odontocetes with a highly developed biosonar system. This dissertation examines the hearing ability of several odontocete species to understand what signals they can perceive during echolocation. The variability in hearing ranges between species is examined in the context of phylogenetic and ecological differences among taxa. An autonomous hydrophone array is also developed that could be used in an expanded form in field deployments to study echolocation signals in a wider range of species.
Methods for measuring hearing sensitivity include both psychophysical and electrophysiological procedures. Behavioral methods require a large time commitment, for both training and data collection, and can only be performed on captive dolphins. Auditory evoked potential (AEP) methods are non-invasive, rapid measurements of the brain's response to sound stimuli and allow for audiograms to be collected on stranded, high risk dolphins. By determining the hearing abilities of odontocetes either in captivity or during stranding, data can be collected about inter- and intraspecies variability, and the occurrence of hearing impairment. It can also be used as another diagnostic tool to determine the releasability of a stranded animal.
A juvenile male short-finned pilot whale (Globicephala macrorhynchus) that stranded in Curacao had severe hearing impairment at all frequencies tested. Four female short-finned pilot whales tested had the best sensitivity at 40 kHz. The juveniles had greater high frequency sensitivity than the adult pilot whales. Cutoff frequencies were between 80 and 120 kHz.
Hearing sensitivity was determined for the two mother/calf pairs of Risso's dolphins (Grampus griseus) before and after antibiotic treatment in order to measure any potential effects of antibiotic treatment. Greatest sensitivity occurred at 40 kHz and cutoff frequencies were around 120 kHz for all dolphins tested. Changes in hearing sensitivity after antibiotic dosage were 12 dB or less in all cases except one. The adult female Betty showed a threshold shift at 120 kHz of 54 dB from May to June, which partially demonstrates the presence of an ototoxic effect at one frequency. Dosages of antibiotics during drug treatment detailed in this study should be considered safe dosages of antibiotics for Risso's dolphins.
AEP and behavioral methods were used to collect audiograms for three Stenella spp. dolphins. The frequency of best hearing for the Atlantic spotted dolphin and the spinner dolphin was 40 kHz, and their upper cutoff frequencies were above 120 kHz. The pantropical spotted dolphin had the greatest sensitivity at 10 kHz, and had severe high frequency hearing loss with a cutoff frequency between 14 and 20 kHz.
Comparisons of high frequency hearing sensitivities among the species tested show two distinct groups. Short-finned pilot whales and Risso's dolphins have a cutoff frequency below 120 kHz, whereas Stenella spp. dolphins have cutoff frequencies above 120 kHz. Expanding the comparison to include other species, killer whales, pygmy killer whales, false killer whales, and long-finned pilot whales also have cutoff frequencies below 120 kHz. Common bottlenose dolphins, white-beaked dolphins, Indo-Pacific humpback dolphins, rough-toothed dolphins, and common dolphins have cutoff frequencies above 120 kHz. Genetic evidence exists for two subfamilies within Delphinidae (Vilstrup et al., 2011) and those species with cutoff frequencies below 120 kHz belong to the subfamily Globicephalinae and those species with cutoff frequencies above 120 kHz belong to the subfamily Delphininae.
An autonomous, field-deployable hydrophone array was developed to measure free-swimming echolocation. The array contained 25 hydrophones, two cameras, and a synchronization unit on a PVC frame. The distinct click train was used to time-align all 25 channels, and the light was used to synchronize the video and acoustic recordings. Echolocation beam patterns were calculated and preliminary evidence shows a free-swimming dolphin utilizes head movement, beam steering and beam focusing.
Among all areas of cetacean biology more research is necessary to gain a clearer picture of how odontocetes have adapted to function in their acoustic environment. The array system developed can be used to study how dolphins use echolocation in the wild, the impacts of anthropogenic sound on echolocation production, and the potential consequences of high frequency hearing loss.

Full textAbstract:
Power electronics applications in high power are normally large, expensive, spatially distributed systems. These systems are typically complex and have multiple functions. Due to these properties, the control algorithm and its implementation are challenging, and a different approach is needed to avoid customized solutions to every application while still having reliable sensor measurements and converter communication and control.
This thesis proposes a synchronous digital control architecture that allows for the communication and control of devices via a fiber optic communication ring using digital technology. The proposed control architecture is a multidisciplinary approach consisting of concepts from several areas of electrical engineering. A review of the state of the art is presented in Chapter 2 in the areas of power electronics, fieldbus control networks, and digital design. A universal controller is proposed as a solution to the hardware independent control of these converters. Chapter 3 discusses how the controller was specified, designed, implemented, and tested. The power level specific hardware is implemented in modules referred to as hardware managers. A design for a hardware manager was previously implemented and tested. Based on these results and experiences, an improved hardware manager is specified in Chapter 4. A fault tolerant communication protocol is specified in Chapter 5. This protocol is an improvement on a previous version of the protocol, adding benefits of improved synchronization, multimaster support, fault tolerant structure with support for hot-swapping, live insertion and removals, a variable ring structure, and a new network based clock concept for greater flexibility and control. Chapter 6 provides a system demonstration, verifying the components work in configurations involving combinations of controllers and hardware managers to form applications. Chapter 7 is the conclusion. VHDL code is included for the controller, the hardware manager, and the protocol. Schematics and manufacturing specifications are included for the controller.

Previous issue date: 2011-03-02Starting from the premise that language is a form of social action, the main aim of this study is to examine how students of an Adults Education Program (AEP), from a public school located in a peripheral neighborhood of a city in Minas Gerais, build and take their social identities. Grounded in theories of Ethnomethodological Conversation Analysis (ECA) and in Interactional Sociolinguistics (IS), we analyze the linguistic and discursive choices of these students, observed from the talk-in-interaction in a focus groups, to identify how these students demonstrate membership in certain social categories. To collect the data, we used a focus group, through which students narrated their experiences of living in a peripheral neighborhood. After a detailed transcript of the data generated in the meetings with students, which was done according to the proposal from ECA, we analyzed it based on the concept of Sacks‟ Membership categorization (1992). Since the categorization processes are in use and in constant negotiations, we revealed, thus, students' discursive action, during interactions with one another, to build their identities through self-categorization and categorization. The results of this research indicate participants‟ orientation throughout the interaction, building, through speech, the identity of outsiders, ratifying the label assigned to them by those who occupy prestigious positions of power and by those who recognize themselves as the "good society", as Elias e Scotson (2000). By categorizing themselves as deviant, the participants seem to perceive their place in the city surveyed, but, they do not often accept this label passively: this generates reports of a conflictual relationship between these young people and the members of the so-called "good society". Thus, we conclude that through membership categorization, students build and assume the identity of outsiders, and that a description and categorization work is quite relevant to the study of the construction of social identities.
Partindo da premissa básica de que a linguagem é uma forma de ação social, o objetivo central deste estudo é analisar como alunos da Educação de Jovens e Adultos (EJA) de uma escola pública localizada em um bairro periférico de uma cidade do interior de Minas Gerais constroem e assumem as suas identidades sociais. Embasados em teorias da Análise da Conversa Etnometodológica (ACE) e da Sociolinguística Interacional (SI), analisamos as escolhas linguístico-discursivas desses alunos, observadas a partir da fala-em-interação em grupos focais, para verificar como esses estudantes demonstram pertencimento a determinadas categorias sociais. Para coleta de dados, utilizamos a técnica do grupo focal, através da qual os discentes narram a experiência de morar em um bairro periférico. Após uma minuciosa transcrição dos dados gerados nos encontros com os estudantes, feita de acordo com a proposta da ACE, fizemos uma análise baseada no conceito de Categorização de Membros, de Sacks (1992). Uma vez que os processos de categorização estão em uso e negociações constantes, revelamos, assim, a ação discursiva dos estudantes, durante interações entre si, para a construção de suas identidades por meio de autocategorização e categorização. Os resultados desta pesquisa apontam a orientação dos participantes durante a interação, os quais constroem, através da fala, a identidade de outsiders, ratificando o rótulo que lhes é atribuído por aqueles que ocupam posições de prestígio e poder e que se reconhecem como a boa sociedade , os quais chamaremos de estabelecidos, assim como Elias e Scotson (2000). Ao se categorizarem como desviantes, os estudantes de EJA demonstram perceber o lugar deles na cidade pesquisada, mas, muitas vezes, não aceitam passivamente tal rótulo, o que gera relatos de uma relação conflituosa entre esses jovens e os estabelecidos. Assim, ao concluir que, através da categorização de membros, os estudantes constroem e assumem a identidade de outsiders, demonstramos que o trabalho de descrição e de categorização de membros é bastante pertinente para o estudo da construção de identidades sociais.

Abstract
Purpose: To compare the frequency specific Cortical Auditory Evoked Potential
(CAEP) and the chirp-evoked 40 Hz Auditory Steady State Response (ASSR) with
equivalent residual noise levels for behavioural threshold prediction in adults with normal hearing and with SNHL.
Method: The study tested 23 adults with normal hearing and 20 adults with SNHL. The participants were aged between 18–65 years. A repeated measures within-
participant descriptive design was used to collect the quantitative data. The participants underwent behavioural pure tone, CAEP and ASSR testing on the same day.
Results: Similar CAEP difference scores across frequencies for the participants with normal hearing (mean=12.32-14.40 dB) and with SNHL (mean=10.00-16.47 dB) were measured. However, for the ASSR difference scores across frequencies slightly smaller difference scores were measured for the participants with SNHL
(mean=10.17-17.30 dB) than for the participants with normal hearing (mean=11.74- 17.14 dB). CAEP thresholds were significantly closer to the behavioural pure tone thresholds at 500 (p=0.028; mean absolute difference 14.40 dB) and 2000 (p=0.016; mean absolute difference 12.56 dB) Hz for participants with normal hearing. In participants with sensorineural hearing loss, CAEP and ASSR thresholds were measured at similar sensation levels and were not statistically different (p>0.05).
Conclusion: For the purpose of threshold estimation, representing the auditory
function to the level of the auditory cortex the CAEP was closer to the behavioural
hearing thresholds than the 40 Hz ASSR at all frequencies except at 4000 Hz, regardless of the hearing sensitivity.

Full textAbstract:
Les antennes présentes dans la plupart des systèmes communicants comme les véhicules automobiles, les avions et les trains se multiplient et sont soumises à une contrainte d’intégration de plus en plus sévère. De nombreuses techniques de miniaturisation d’antennes existent et passent toutes par un compromis entre la taille et les performances (bande passante et/ou rendement de rayonnement). Pour les systèmes cités ci-dessus, les antennes sont souvent placées devant ou à proximité d’un réflecteur métallique (toit de véhicule, carlingue d’aéronef). Dans ce cas, l’épaisseur de système antennaire est une contrainte majeure et les métamatériaux de type Conducteur Magnétique Artificiel (CMA) ouvrent des perspectives intéressantes grâce à leurs propriétés électromagnétiques non conventionnelles. Cependant, pour les applications sub-GHz (RFID, LTE, PMR…), les CMA sont limités par les dimensions des cellules unitaires nécessaires à leur mise en œuvre (λg/4) ainsi que leur bande réduite de fonctionnement. Réduire leurs dimensions permet de rendre leur utilisation compatible avec le contexte des antennes miniatures intégrées. Ajouter l’agilité fréquentielle permet de palier le problème de la bande passante réduite dans le cas des antennes et des CMA miniaturisés en ajustant le fonctionnement du système antennaire sur une large bande passante. Cette thèse de doctorat propose d’étudier et de développer un nouveau système antennaire à faible profil composé d’une antenne miniature associée à une métasurface compacte reconfigurable en fréquence et compatible avec le standard NB-IoT dans la bande basse LTE (700 MHz – 960 MHz)Antennas are now very integrated in several connected systems like cars, airplanes and trains. Many antenna miniaturization techniques exist and all go through a compromise between size and performance (bandwidth and/or radiation efficiency). For the systems mentioned above, the antennas are often placed near a metallic reflector (vehicle roof, aircraft cabin). Within this context, Artificial Magnetic Conductors (AMC) present an attractive reflector for low profile antennas which can take advantage of intrinsic zero reflection phase response to boost antenna performance without the need for thick quarter wave backplane. However, for sub-GHz applications (RFID, LTE, PMR ...), AMC are limited by the size of the unit cells necessary for their implementation (λg/4) as well as their reduced operating bandwidth. AMC miniaturization makes their use compatible with small antennas. Adding tunability restores the possibility of adjusting the operating frequency over a large bandwidth. This PhD thesis proposes to study and develop a new electrically small, low-profile antenna based on miniaturized and tunable AMC for the NB-IoT standard in low LTE band (700 MHz – 960 MHz)

A ce jour, six millions de français sont atteints de troubles de l'audition. Face à ce problème de santé publique, des outils performants d'exploration de la fonction auditive sont indispensables. La Speech ABR (Speech Auditory Brainstem Response ou Réponse du tronc cérébral auditif à la parole) est un outil prometteur, comme marqueur électrophysiologique fin de l'encodage neuronal de la parole. Cependant, sa méthodologie reste peu développée, son origine neuronale incertaine et elle n'a jamais été enregistrée chez le malentendant porteur d'aides auditives. Le premier axe de cette thèse porte sur les générateurs neuronaux de la Speech ABR. Le développement d'une méthodologie de recueil topographique de cette réponse jusqu'alors décrite comme strictement sous-corticale, a d'abord suggéré la possibilité d'un générateur cortical. Une étude en stéréo-électroencéphalographie a ensuite confirmé l'existence d'une activité Speech ABR dans les cortex auditifs primaires bilatéraux. Ce résultat apporte un éclairage nouveau sur la représentation des sons de parole par système nerveux auditif. Le second axe concerne l'étude de la Speech ABR chez le malentendant appareillé. Après avoir développé une méthodologie de stimulation acoustique directement au travers des aides auditives, nous avons étudié la plasticité neuronale induite par le port d'aides auditives. Les résultats montrent une amélioration de l'identification des phonèmes amplifiés, liée à une représentation corticale modifiée et à un encodage fréquentiel rééquilibré. Ces toutes premières preuves de plasticité neuronales dès les 4 premiers mois d'utilisation des aides auditives ouvrent de nouveaux espoirs thérapeutiquesTo date, six million French are hearing impaired. To address this public health issue, efficient tools for exploration of the hearing function are essentials. Speech ABR (Speech Auditory Brainstem Response) is a promising tool, being a fine electrophysiological marker of the neuronal encoding of speech. Though, its methodology remains underdeveloped, its neural origin is still uncertain, and it has never been recorded in hearing aid users. The first axis of this thesis focuses on the neural generators of Speech ABR. The development of a methodology for recording topographies of this response, up to now described as strictly subcortical, first suggested the possibility of a cortical generator. A stereo-electroencephalography study then confirmed the existence of Speech ABR activity in bilateral primary auditory cortices. This result sheds a new light on the representation of speech sounds within the auditory nervous system. The second axis concerns the study of Speech ABR in hearing aid users. After having developed a methodology of acoustic stimulation directly through hearing aids, we investigated neural plasticity induced by hearing aid use. Results show an improvement in the identification of amplified phonemes, linked to an altered cortical representation and a rebalanced frequency encoding. This very first evidence of neural plasticity as soon as the first four months of hearing aid use opens up new therapeutic hopes

Full textAbstract:
Relatório de estágio de mestrado em Educação (área de especialização em Formação, Trabalho e Recursos Humanos)A gestão da formação é um processo crucial que se reflecte nas práticas formativas. A literatura académica não é unânime na definição de formação, nem tão pouco na forma como esta deve ser gerida. Pode-se, contudo, como neste estudo se procura mostrar, identificar algumas abordagens centrais face a esta problemática. Muitas destas abordagens apresentam um cariz tecnicista, concebendo a formação como um elemento essencial para cumprir com os requisitos do desenvolvimento de competências técnicas que sirvam para um bom desempenho no posto de trabalho. Simultaneamente, exclui-se do campo da formação dimensões relacionais, individuais e contextuais, centrais para a formação do indivíduo. Outras abordagens apresentam um conjunto de visões, de um pendor mais humanista, centradas no envolvimento dos actores no processo formativo, perspectivando a formação não só como elemento favorecedor do trabalho e da economia mas também, e sobretudo, como uma fonte de satisfação e de melhoria das condições pessoais e sociais. Neste trabalho, e perante estas perspectivas, traçou-se um percurso investigativo de forma a constatar quais são os sentidos dados à formação quando esta é posta em prática, no caso concreto numa Associação Empresarial. Estes “sentidos” são dados por todos aqueles que colaboram no processo formativo, nomeadamente por aqueles que gerem a formação e que acompanham o seu desenvolvimento no decorrer do tempo – os técnicos/consultores de formação. Estes actores do processo formativo são os “responsáveis” pelas acções de formação e, por isso, pela boa execução das tarefas de concepção, preparação, desenvolvimento e avaliação da formação/acção. Este trabalho afigura-se como um contributo para um melhor entendimento das práticas de gestão da formação e sobre a forma como elas são congruentes, ou não, com as diversas perspectivas teóricas. Nele se conclui que as práticas de desenvolvimento da formação e da sua gestão se inserem numa perspectiva neo-taylorista de actuação, consolidando uma concepção de formação essencialmente tecnicista, tanto no seu conteúdo como na sua forma de gestão.
The management training is a crucial process that is reflected in training practices. The academic literature is not unanimous on the definition of training, nor on how this should be managed. You can, however, as this study attempts to show, to identify some core approaches address this problem. Many of these approaches have a technicist nature, conceiving education as an essential element to comply with the requirements of the development of technical skills that will serve for a good performance on the job. At the same time, is excluded from the training field relational dimensions, individual and contextual, central to the formation of the individual. Other approaches have a number of visions of a more humanistic bent, centered on the involvement of actors in the training process, viewing the formation not only as element to facilitate the work and the economy but also and especially as a source of satisfaction and improvement of personal and social conditions. In this work, and before these prospects, was drawn up an investigative journey in order to see what are the directions given to the training when it is put into practice, in this case a Business Association. These "senses" are given by all those who collaborate in the formation process, particularly by those who manage training and accompanying its development over time - the technical / training consultants. These “actors” in the training process are responsible for training and, therefore, the proper execution of the tasks of design, preparation, development and evaluation of training / action. This work appears as a contribution to a better understanding of management practices and training on how they are congruent or not with the various theoretical perspectives. It concludes that the development of training practices and its management are part of a neo - Taylorist action, consolidating a design essentially technical training, both in its content as in its management.

Full textAbstract:
Protein synthesis in archaebacteria and the cytoplasm of eukaryotes is initiated using the initiator methionyl-tRNA (Met-tRNA[subscript i][superscript Met]). In contrast, formylated methionyltRNA (fMet-tRNA[subscript i][superscript Met][subscript f]) is found in eubacteria, and in chloroplasts and mitochondria of eukaryotes, and this formylated initiator tRNA was widely believed to be required for initiation of protein synthesis in those systems. However, the fact that initiation of protein synthesis in yeast mitochondria can occur with unformylated initiator tRNA has changed our perspective about the initiation of mitochondrial protein synthesis. This dissertation is composed of two parts. Part I describes an investigation of the yeast AEP3 gene which was isolated by a genetic screening system in Saccharomyces cerevisiae. The main goal of this part was to discover new accessory factor(s) that might be involved in initiation of protein syntheis of yeast mitochondria when there is no formylation of initiator tRNA and determine how they support the initiation process in Saccharomyces cerevisiae. The synthetic petite genetic screen identified the AEP3 gene. Protein-protein binding assays as well as protein-initiator tRNA binding assays indicate that Aep3p is associated with the initiation process in yeast mitochondrial protein synthesis. This discovery is important because it suggests the possible mechanism by which initiation of protein synthesis in yeast mitochondria occur under conditions where there is no formylation of initiator tRNA. Part II describes a study of the TRM5 gene encoding a tRNA methyltransferase in S. cerevisiae. The TRM5 gene encodes a tRNA (guanine-N1-)-methyltransferase (Trm5p) previously known to methylate guanosine at position 37 (m¹G37) in certain cytoplasmic tRNAs in S. cerevisiae. The main goal of this part was to investigate whether Trm5p is also responsible for m¹G37 modification of mitochondrial tRNAs. Full-length Trm5p, purified as a fusion protein with maltose-binding protein, exhibited robust methyltransferase activity with tRNA isolated from a [Delta]trm5 mutant strain, as well as with a synthetic mitochondrial tRNA[superscript Met][subscript f] and tRNA[superscript Phe]. High pressure liquid chromatography analysis showed the methylated product to be m¹G. Analysis of subcellular fractionation and immunoblotting revealed that the enzyme was localized to both cytoplasm and mitochondria. Our data including the analysis of N-terminal truncation mutants suggest that this tRNA modification plays an important role in reading frame maintenance in mitochondrial protein synthesis.text

Full textAbstract:
The purpose of this research was to ascertain the characteristics of dropouts, their rationale for reentry, and what constituted effective practices within a Texas alternative education program (AEP). While, a number of studies have been conducted to explain why students drop out of school, more research was needed in the area of students that reenter to complete their studies (Fernandez, Paulsen & Hiranko-Nakanishi, 1996; Krashen, 1998; NCES, 1981; Pirog & Magee, 1997; Ramsey, 1988; Rumberger, 1995; Warren, 1996; White & Kaufman, 1997). The study utilized qualitative methodology with a case-study approach by utilizing small groups within the context of an organization (Miles and Huberman, 1994). The study site was purposely selected (Kuzel, 1992; Morse, 1989) using low-socio-economic criteria, ethnic representation, an AEIS rating of Commended, and a high graduation rate. Site participant selection included comprehensive sampling (Goetz and LeCompte, 1984) of the AEP personnel and random sampling of the student participants and their respective parents. The primary data was collected using a modified three-interview method (Dolbeare and Schuman, 1982) with corroborating document review and focus groups. Findings indicated that research participants could identify seventeen different characteristics for returning high school students. Some of the characteristics describing these students also reflect their motivation or rationale for returning back to complete their high school studies. The study revealed four major practices within the AEP that supported the program and its students towards their mission of graduating. These were: hiring the right personnel, monitoring academic progress, providing student support services, and maintaining a safe school climate. A resultant theme indicated that there was a need to promote a positive image of the value of the AEP. Since only ten participants and five students were included in the study, the findings can only be tentatively generalized. Finally, suggestions are made for AEP programs to be designed to entice students not only to return back to school, but to remain until their goal to graduate is realized.text
