Molteni, Jara María Cecilia. "Pertinencia cultural de los medios periodísticos nacionales en la región magallánica." Tesis, Universidad de Chile, 2004. http://repositorio.uchile.cl/handle/2250/146103.
Full textAbstract:
Seminario para optar a la Licenciatura en Comunicación Social<br>Este trabajo ha pretendido determinar la pertinencia cultural que la oferta informativa de los medios periodísticos nacionales presenta para los habitantes de la Región de Magallanes y Antártica Chilena, entendiendo como pertinencia cultural la manifestación de elementos sustantivos -en forma y contenido- que interpelan espontáneamente el modo de ser intrínseco de los sujetos que comparten una identidad.
En la base, se encuentra la pregunta acerca del modo y rango en que los medios de comunicación nacionales están respondiendo a las necesidades de información de quienes no viven en Santiago y de cómo están participando en la preservación una homogenización artificial de la chilenidad en desmedro de la diversidad cultural del país.
Debido a que el objetivo planteado sólo puede abordarse adecuadamente, mediante un estudio de orden cualitativo - ya que hablamos de consumo cultural e identidad- nos inscribimos en el enfoque epistemológico constructivista y utilizamos la técnica de los grupos de discusión.
Analizamos los distintos relatos, desde las perspectivas de los hábitos informativos, preferencias por medios regionales o nacionales, necesidad y valoración de la información, modos en que se representa a la región magallánica en los medios nacionales, elementos culturales de la oferta noticiosa que comparten y se consideran propios.
El resultado es significativo. Los magallánicos hacen una crítica profunda a los medios periodísticos nacionales, su calidad, contenidos y función social. A la vez, con excepción de escasos temas de orden político, económico y social, la información les resulta ajena, sin interés y culturalmente amenazante para el futuro del país.

Full textAbstract:
L’ouverture du secteur audiovisuel camerounais a consacré l’avancée du processus d’acquisition et de l’octroi des libertés individuelles commencé autour des années 1990. Le décret d’application d’avril 2003 a entériné une dizaine d’années plus tard, le dispositif enclenché par la loi n°90-052 du 19 décembre 1990 relative à la liberté de communication sociale. Depuis lors, organes de presse et audiovisuels se côtoient et se heurtent à des pesanteurs susceptibles de limiter leur efficacité, en tant qu’outils et moyens de communication de proximité. Leur jeunesse, les problèmes endogènes et exogènes au paysage médiatique camerounais justifierait une étude sur l’existence et la manière dont les organes de communication sociale produisent et diffusent informations et nouvelles en direction des populations ciblées. A ce sujet, la radio communautaire, tout en cherchant à les impliquer et à les faire participer à cet objectif de communication sociale, promeut par ses programmes, la propre image des populations à laquelle elle est destinée. Il ne reste qu’à garantir les modalités pratiques, les conditions nécessaires pour une participation transparente des différents acteurs à la gestion et au fonctionnement de la radio. Pour une grande part, les populations sont prêtes à soutenir les projets de radios communautaires qui s’installent dans les localités. Les différentes techniques d’appropriation et d’usage des médias permettent d’appréhender de l’extérieur les différents enjeux qui se tissent. Elles permettent d’observer les pratiques mises en place et les conditions d’engagement des acteurs sociaux pour garantir, une longue vie à la radio<br>The opening of the Cameroonian audiovisual sector dedicated the overhang of the process of acquisition and the granting of the personal freedoms begun around 1990s. The application decree of April, 2003 confirmed a decade later, the plan engaged by the law 90/052 of December 19th, 1990 relative to the freedom of social communication. Since then, newspapers and broadcasting mix and come up against gravities susceptible to limit their efficiency, as tools and means of communication of nearness. Their youth, the endogenous and exogenous problems in the Cameroonian media landscape justify a study on the existence and the way the organs of social communication produce and broadcast information and news in the direction of the targeted populations. For this subject, the community radio, while trying to imply them and to make them participate in this objective of social communication, promotes by its programs, the own image of the populations for which is intended. It remains only to guarantee the practical methods, the necessary conditions for a transparent participation of the various actors in the management and in the functioning of the radio. Mostly, the populations are ready of supporting the projects of community radios which settle down in villages. The various techniques of appropriation and uses of the media allow dreading from the outside the various stakes which weave. They allow observing the organized practices and the conditions of commitment of the civil society to guarantee, a long life on the radio

Full textAbstract:
Capturing Believers provides a history of the reception of American conservative evangelical missionary broadcasting from its inception in 1931 through the rise of the commercial era in 1970. The dissertation narrates accounts of two major Protestant stations, HCJB and ELWA, located in Ecuador and Liberia, respectively, as well as the U.S.-based project to build a custom transistor radio for the mission field. Employing a case-study approach, the thesis demonstrates the innovativeness of religious broadcasters who formulated a range of pragmatic responses to the drastic shortage of receiving sets in the southern hemisphere, including the use of social convention and the development of pretuned receiver technology. Missionary stations imported not only radios, but a constellation of American values into host countries through their reception activities. Overall, officials employed creative methods to construct a particular type of listener experience known as radio capture, characterized by regular listening in a domestic setting. By penetrating into the home or village and exposing listeners to proprietary broadcasts on a continual, even daily, basis, missionary receiver programs legitimized American conservative evangelicalism abroad and sowed seeds for a widespread revival of Protestantism in Latin America and Africa after 1970.

Full textAbstract:
Dans cette thèse, nous nous demandons comment les mouvements contreculturels ont trouvé de nouveaux lieux d’expression grâce à la plus grande accessibilité de l’audiovisuel, grâce aussi au combat des « radios libres ». Plus précisément, nous cherchons à savoir pourquoi et comment la société et l’audiovisuel français ont permis la constitution d’un média alternatif radiophonique comme Radio Ici et Maintenant (RIM) et comment cette radio a trouvé un modèle économique viable pour diffuser son idéologie. Nous verrons que l’existence et la persistance de RIM est due à la conjonction de deux phénomènes : d’une part la diminution du coût d’entrée dans la radiophonie grâce au développement et au combat des « radios libres » qui ont donné naissance aux radios associatives (avec leur modèle juridico-économique spécifique), et d’autre part la diminution du coût d’entrée dans le marché religieux avec le développement de la contreculture New Age française issue de la contreculture américaine, elle-même issue des pensées religieuses alternatives occidentales (liées à l’ésotérisme, au médiumnisme) et des religions orientales (l’hindouisme et le bouddhisme). Ainsi, le modèle juridico-économique spécifique des radios associatives a permis de faire vivre puis persister l’idéologie « radiolibriste » et New Age au sein de RIM. Mais ajoutons que ce modèle n’aurait pas été possible s’il n’avait pas été porté par des animateurs bénévoles, des invités militants et des auditeurs actifs dont nous analysons ici le profil sociologique. L’intérêt scientifique de ce sujet provient du fait qu’il s’agit principalement d’étudier RIM qui est une ancienne « radio libre ». Elle a été l’une des radios les plus importantes au sein du mouvement. C’est la plus ancienne des radios locales privées parisiennes. C’est aujourd’hui une radio associative de catégorie A. Cette catégorie correspond à un grand nombre de radios (environ 600), mais celles-ci sont peu étudiées. Enfin, c’est une radio New Age et l’un des seuls médias audiovisuels français New Age. Croisant histoire et sociologie du religieux, des médias, de la communication, de la politique, des sciences, cette thèse repose sur une écoute assidue, sur de nombreux entretiens et discussions informelles, sur l’étude de différents fonds d’archives (papier, audio, numérique) et sur de nombreuses observations de type ethnographique. Nous donnons dans une première partie les outils scientifiques pour pouvoir analyser ce phénomène. Nous verrons ensuite dans quel contexte historique, radiophonique, économique, social, juridique et politique RIM fait son apparition et continue d’exister aujourd’hui. Enfin, nous nous focalisons sur le modèle radiophonique proposé, et sur les acteurs de cette radio<br>In this thesis, we wonder how countercultural movement found new places of expression through the increased accessibility of audiovisual, thanks to "free radio" fight. Specifically, we want to know why and how society and the French media have enabled the establishment of an alternative media like Radio Ici et Maintenant (RIM) and how this radio has found a viable business model to spread its ideology. We shall see that the existence and persistence of RIM is due to the combination of two factors: firstly the reduction in the cost of entry into the radio broadcasting through the development and struggle of "free radio" that gave birth to associative radios (with their specific legal and economic model) and also the decrease in the cost of entering the religious market with the development of the French New Age counterculture issue of the American counterculture, itself the result of religious thoughts Western alternatives (related to the esoteric, the mediumship) and Eastern religions (Hinduism and Buddhism). Thus, the specific legal and economic model of associative radios allowed to live and persist "radiolibriste" and New Age ideology within RIM. But add that this model would not have been possible if it had not been worn by volunteer facilitators, invited activists and active listeners which we analyze the sociological profile. The scientific interest of this subject is the fact that it is mainly to study RIM which is an old "free radio". She was one of the most important radio stations in the movement. It is the oldest Parisian private local radio station. Today, it is a community radio (category A). This category corresponds to a large number of radio stations (about 600), but these are little studied. Finally, this is a New Age radio and one of the only French audiovisual media New Age. Crossing history and sociology of religion, media, communication, politics, science, this thesis is based on a constant listening, on numerous interviews and informal discussions on the study of different archives (paper, audio, digital) and numerous ethnographic observations. We give in the first part scientific tools to analyze this phenomenon. We will then see in which historical, radio, economic, social, legal and political context RIM appeared and continues to exist today. Finally, we focus on the proposed radio model and the actors of this radio

Full textAbstract:
In questa tesi studiamo il ruolo dei sistemi di radici nella classificazione delle algebre di Lie e delle superalgebre di Lie. L'interesse per le superalgebre di Lie nasce nei primi anni '70 quando una parte dei fisici si convinse che sarebbe stato più utile e molto più chiaro riuscire ad avere uno schema di riferimento unitario in cui non dovesse essere necessario trattare separatamente particelle fisiche come bosoni e fermioni. Una teoria sistematica sulle superalgebre di Lie fu introdotta da V. Kac nel 1977 che diede la classificazione delle superalgebre di Lie semplici su un campo algebricamente chiuso.

Full textAbstract:
One of the common failure modes of the diesel engine turbochargers is high-cycle fatigue of the turbine-wheel blades. Mistuning of the blades due to the casting process is believed to contribute to this failure mode. A laser vibrometer is used to characterize mistuning for a population of turbine wheels through the analysis of the blade-response to piezo-speaker induced noise. The turbine-wheel design under investigation is radial and is typically used in 6-12L diesel engine applications. FRFs and resonance frequencies are reviewed and summarized. The study includes test results for a paddle wheel that represents a perfectly tuned system and acts as a reference. A discrete mass-spring model is developed for the paddle wheel and the model suitability is tested against measured data. Density randomization is applied to model mistuning in the turbine wheels. Frequency mistuning and relative amplitude modelling for blade modes is found in good agreement with the data, however the mass-spring model over-predicts amplitude-amplification factors for a population of radial-turbine wheels, especially with regard to hub-dominant modes. A continuous twisted-blade model is developed in Matlab using finite-element techniques. Experimental data is shown to have good agreement with the twisted-blade model. Whitehead’s maximum amplitude-amplification prediction using RMS value for a tuned amplitude value is calculated, and the turbine-wheel response is found to fit within the theoretical limit. Different mistuning patterns are studied using the twisted-blade model. Maximum and minimum response patterns are identified and recommended.

La presente investigación se enmarca en el programa de Licenciatura de Comunicación Social en la Universidad Nacional Mayor de San Marcos, impartido por la Facultad de Letras y Ciencias Humanas de esta casa de estudios y pretende estudiar los efectos de programa radial Mi novela favorita en las capacidades comunicativas de los alumnos de la Institución Educativa Privada América International School de Lima. Un punto de partida para la realización de este estudio es el interés por conocer sobre las adaptaciones radiales y otro es la preocupación por el desarrollo de las capacidades comunicativas en los alumnos de secundaria. Diversos autores destacan la presencia de la literatura en la radio ya sea en programas educativos o en adaptaciones radiales, como en el caso a estudiar. Se trata del programa Mi novela favorita, producida por Radio Programas del Perú, con un equipo de primer nivel, además con la selección y presentación de nuestro Premio Nobel Mario Vargas Llosa. En otras investigaciones se han hecho referencia a las adaptaciones radiales, pero en este caso existe la particularidad de ser un proyecto netamente peruano y con un ambicioso objetivo: educar entreteniendo. El aprendizaje de las capacidades comunicativas de los estudiantes en nuestro país se encuentran disminuidas, diversos estudios así lo sustentan, y se dice también que la falta de estas capacidades mermará, en un futuro, el desarrollo integral del estudiante. También existe la necesidad de acercar al público, en especial al alumno, a la literatura, de la que progresivamente se ha ido alejando. Esta investigación consta de cuatro capítulos, en el primero se plantea el problema, para ello se realiza un diagnóstico del fenómeno a estudiar, dando por efecto la formulación del problema; a su vez, se explican la importancia, los alcances de la investigación y sus limitaciones. El segundo capítulo contiene el marco teórico, donde se presentan los antecedentes de la investigación, los fundamentos teóricos, las concepciones y enfoques sobre las variables y la definición de términos básicos. En el tercer capítulo se fundamentan y formulan las hipótesis; se identifica, clasifica y operacionaliza las variables. En el cuarto capítulo se enuncia la metodología el presente estudio, se trata de una investigación aplicada, el método es el deductivo-inductivo, el diseño de investigación es el cuasiexperimental – explicativo. Asimismo nos referimos a la población, muestra y los instrumentos de recolección de datos. El quinto capítulo desarrolla la estrategia utilizada para la prueba de hipótesis, se expone la presentación, análisis e interpretación de los datos a través de gráficos y datos comparativos entre el grupo experimental y el grupo control; así también, el proceso de prueba de hipótesis, la discusión de los resultados y la adopción de las decisiones; también se añade una interpretación cualitativa, realizada a través de una guía de observación sobre las capacidades comunicativas de los alumnos que corresponden a la muestra. Finalmente se presentan las conclusiones y se sugieren algunas recomendaciones de la investigación, acompañadas de las referencias bibliográficas y los anexos que ilustran y ayudan a su mejor comprensión. Se adjunta la matriz de consistencia, los instrumentos de recolección de datos entre ellos el resumen de la validación, las tablas utilizadas y la reseña histórica del centro educativo donde se realizó el estudio.<br>Tesis

Full textAbstract:
Understanding of plasma confinement modes is an essential component in development of a fusion reactor. Plasma confinement directly relates to performance of a fusion reactor in terms of energy replacement time requirements on other design parameters. Although a variety of levels of confinement have been achieved under different operating conditions in tokamaks, tokamak confinement is generally identified as being either Low (L-mode--poor confinement) or High (H-mode--good confinement)
In operation of a tokamak experiment, the plasma confinement condition generally changes from L-mode to H-mode over a few hundred milliseconds, sometimes quite sharply. Such a difference in transition period seems to be largely due to operating conditions of the plasma. Comparison of experimental data exhibits various distinctions between confinement modes. One noteworthy distinction between confinement modes is development of steep density and temperature gradients of electrons and ions in the plasma edge region of High confinement, H-modes, relative to Low-confinement, L-modes.
The fundamental reason for the change for L-mode to H-mode is not understood. Previous studies have suggested i) the development of reduced diffusive transport coefficients that require a steepening of the gradients in a localized region in the edge plasma, the "transport barrier" in H-mode confinement ii) the radial force balance between pressure gradient forces and electromagnetic (radial electric field and VxB) forces require radial particle fluxes to satisfy a pinch-diffusion relation. A recent study suggests that the major difference between L-mode and H-mode are associated with the electromagnetic forces in the "pinch velocity" and the pressure gradient, not in the diffusion coefficients that multiplies the pressure gradient.
The research will examine in detail the time evolution of the radial force balance and the particle and energy transport during the L-H transition. For the analysis, DIII-D shot #118897 is selected for transition between L- and H-mode confinements. Plasma conditions in L-mode, near the L-H transition and following the transition are selected for analysis of various parameter profiles.
The initial analysis will be based on the four principal equations for plasma: particle balance, momentum balance, force balance and heat conduction. Based on these equations, specific equations have been derived: toroidal and radial momentum balances, diffusion coefficient, pinch velocity and heat conduction relation for calculation of parameters. The analysis of these equations, using the measured data, will establish how various terms in the radial force balance (radial electric field, VXB (electromagnetic) force, and pressure gradient) and the diffusive transport coefficients evolve over the confinement mode transition.

<p>The demands for ride comfort quality in today's long haulage trucks are constantly growing. A part of the ride comfort problems are represented by internal vibrations caused by rotating mechanical parts. This thesis work focus on the vibrations generated from radial runout on the wheels. These long haulage trucks travel long distances on smooth highways, with a constant speed of 90 km/h resulting in a 7 Hz oscillation. This frequency creates vibrations in the cab, which can be found annoying. To help out with the vibration diagnosis when a truck enters a mechanical workshop, this work studies methods for radial runout detection using the wheel speed sensors.</p><p>The main idea is to represent the varying radius signal with a sinusoid, where the calculations are based on Fourier series. The estimated radial runout value is then the amplitude of the sinusoid. In addition to the detection part, the work also present results regarding how the relative phase difference between two wheels with radial runout effects the lateral motion of the cab.</p><p>This thesis work was performed at Scania CV AB in Södertälje, Sweden and all measurements have been full scale experiments on real trucks.</p>

Full textAbstract:
Syfte: Syftet med denna studie är att få en förståelse för och analysera hur kommunikation kan utgöra ett hjälpmedel vid radikal omorganisation i företag/organisation. Metod: I min undersökning har jag använt kvalitativ metod. Teoretisk data har samlats via böcker vilket i studien representerar sekundärdata. För att kunna samla information för empirin har jag använt intervjuer vilket i studien representeras av primärdata. Resultat & slutsats: För att göra en radikal omorganisation, drar jag slutsatsen att företag/organisation behöver utveckla sina kommunikativa färdigheter att gå framåt och göra en förändring. Speciellt när kommunikationen i företag/organisation är dålig, finns det ett behov att engagerar personaler för förändring som ska hända. Kommunikation spelar en central roll i omorganisationen, och fungera som ett verktyg för att hantera motstånd mot förändring och förbättra personalers engagemang på arbetsplatsen. Enligt informanterna kunde bekymmer minskas med hjälp av dialog och debatt. Om företag/organisation är tvingade till förändring till exempel genom statliga krav kan debatter och dialoger med de anställda kommer påverka motstånd till förändringen i sig. De anställda saknar mandat att påverka tvingande beslut. Förslag till fortsatt forskning: Hur kommer medarbetarna att uppfatta den nya organisationen, hur kommer att bli kommunikationen mellan medarbetarna och kommunikationen mellan ledare och medarbetarna i den nya organisationen, är frågor som jag ser till vidare undersökning. Uppsatsen bidrag: Genom den här underökningen fick jag nyare kunskap om kommunikation och omorganisation. Dessutom fick jag bättre förståelse och chefens - och ledarens roll vid kommunikation i förändringsprocessen. Vidare vill jag säga att genom den underökningen fick jag bra information om vilka kommunikationskanaler chefer och ledare använder vid förändringen. Och denna information fick jag från både litteraturen och verkligheten.

method. Solving the interpolant directly has a high computational cost for
large datasets, hence using numerical methods to approximate the interpolant
is necessary. We consider some recent numerical algorithms. Software to implement
radial basis function interpolation and to display the 3D interpolants
obtained, is developed. We present results obtained from using our implementation

In recent years, the Cognitive Radio and Cognitive Network paradigms have received significant attention by the research community. Cognitive Radios and Networks, in their initial formulation, are characterized by the addition of cognition capabilities such as reasoning and learning to wireless devices and networks, with the aim of providing enhanced adaptability and reconfigurability to cope with the ever-growing challenges of radio communications.
The concepts of Cognitive Radio and Network have actually been interpreted in several different ways. In this thesis, we will first of all provide an overview of the different interpretations of Cognitive Radios and Networks, as appeared in the recent literature.
We will then focus on the cognitive adaptation and reconfiguration of devices and networks by means of Artificial Intelligence (AI) techniques. In this respect, we will discuss how two well-known AI techniques, i.e., Fuzzy Logic and Neural Networks, can be used within a cross-layer and cross-device knowledge representation and reasoning architecture to become major enabling technologies for Cognitive Radios and Networks. For each technology we will discuss how it can be effectively adopted to implement key functionalities of cognitive systems, and we will present and discuss example applications such as cross-layer parameter optimization, wireless network access selection and channel assignment. For all the discussed applications, we will present performance evaluation results showing the advantages that the proposed techniques provide with respect to state-of-the-art approaches.

Full textAbstract:
Syfte: Syftet med denna uppsats är att undersöka hur publikmedverkan förändrats i public service-radion i och med digitaliseringen. Publikmedverkan ska undersökas ur flera aspekter men med ett särskilt fokus på nya medieformer. Teori: Då en enskild relevant teori saknas för området publikmedverkan inom public service-radion har tidigare forskning från flera närliggande områden sammanställts i en för uppsatsens syfte unik analysmodell. Denna modell konceptualiserar infrastrukturen för publikmedverkan i public service-radion. Den beskriver hur den tekniska utvecklingen och public service-uppdraget påverkar publikmedverkan och att det främst är nya medier som används för publikmedverkan. Metod: Uppsatsens empiriska undersökning består av en kvantitativ innehållsanalys som mäter utrymmet för publikmedverkan (mängd publikgenererat innehåll i sändning och antal uppmaningar till publikmedverkan) samt vilka medieformer som används för publikmedverkan vid två tillfällen. Undersökningen består av 20 sändningstimmar 1995 och 20 sändningstimmar 2010, jämnt fördelade mellan radiokanalerna P1 och P3. Resultat: Den empiriska undersökningen visar att utrymmet för publikmedverkan har ökat i och med digitaliseringen. Publikmedverkan har även blivit mer kvalitativ, mer spridd över olika ämnen och fått hela programformer som bygger på publikmedverkan. Det visar sig också att public service-uppdraget har en större roll att spela i denna utveckling än digitaliseringens tekniska möjligheter. De nya medierna används nämligen inte i den utsträckning som analysmodellen påvisade. Det förekommer användning av nya medier vilket visar på att public service-radion medvetet förändrar medieformerna för publikmedverkan och det påverkar i sin tur kommunikationen mellan radion och publiken. Det mest använda mediet är dock telefonen som procentuellt ökade användarmässigt mellan mätåren 1995 och 2010. Detta förmodligen på grund av public service-uppdraget och mediets dialogfokuserade utformning. Nyckelord: Publikmedverkan, interaktion, public service, radiojournalistik, nya medier

Full textAbstract:
The adjacency matrix of a graph is a (0, 1)-matrix indexed by the vertex set of the graph. And the signless Laplacian matrix of a graph is the sum of its adjacency matrix and its diagonal matrix of vertex degrees. The eigenvalues and the signless Laplacian eigenvalues of a graph are the eigenvalues of the adjacency matrix and the signless Laplacian matrix, respectively. These two matrices of a graph have been studied for several decades since they have been applied to many research field, such as computer science, communication network, information science and so on. In this thesis, we study k-connected graphs and focus on their spectral radius and signless Laplacian spectral radius. Firstly, we determine the graphs with maximum spectral radius among all k-connected graphs of fixed order with given diameter. As we know, when a graph is regular, its spectral radius and signless Laplacian spectral radius can easily be found. We obtain an upper bound on the signless Laplacian spectral radius of k-connected irregular graphs. Finally, we give some other results mainly related to the signless Laplacian matrix.

Full textAbstract:
Cette recherche présente une analyse historique de la naissance et de l’évolution des radios libres en Italie et en France à partir du début des années soixante-dix jusqu’à la fin des années quatre-vingt au XXe siècle. Le caractère comparatif de la recherche illustre les similitudes et les divergences soit des processus sociaux-historiques, soit des différents systèmes politiques, qui ont déterminé l’apparition et l’évolution de ces formes de communication en dehors du monopole d’Etat et leur intégration à l’intérieur de systèmes médiatiques spécifiques, aux réalités nationales singulières. L’étude s’insère dans l’histoire des médias des deux Pays. Le parcours des radios libres montre de quelle façon on est passé des revendications originelles de la prise de parole libre, d’une communication décentrée, de la réalisation de médias démocratiques, à l’affirmation dans les années quatre-vingt du modèle de la radio commerciale, influencé par la domination de la télévision et de la publicité. L’évolution des radios libres contribue à redéfinir le paysage audiovisuel en décrétant la fin du monopole public du service audiovisuel. Les radios libres, en exprimant le point de vue de groupes politiques, culturels, religieux et de communautés locales, ont représenté un moment d’ouverture et de démocratisation du secteur des médias et d’élargissement de l’espace de la sphère publique. Même si ces objectifs pendant les années quatre-vingt ont été en partie remplacés par l’affirmation des radios à vocation musicale, à cause de situations politique, sociale et économique différentes, l’expérience des radios communautaires, favorisant une communication de proximité sans but lucratif, ont constitué les héritières directes de la période des radios libres. Bien qu’elles n’occupent qu’une place réduite dans les systèmes médiatiques de l’Italie et de la France, ces radios ont démontré l’importance sociale des moyens de communications alternatifs et locaux, au niveau soit des contenus, soit de l’organisation radiophonique, en anticipant en partie des formes d’interactivité qui se développeront dans les décennies suivantes avec la naissance des webradios<br>The thesis presents an historical analysis of the birth and evolution of free radios in Italy and France between the beginning of ‘70s (seventies) and the end of ‘80s (eighties) of the 20th century. The comparative character of the study highlights the similarities and divergences of both the historical-social processes and the various political systems which determined the emergence and transformation of such from-the-ground means of communication, out of the central monopoly of the State as well as their insertion in the proper frame of national media. The study finds its place in the historical context of the two countries. The route of free radios shows how one passed from the original claim of ‘taking-the-word’, of off-centred communication, of realization of democratic media, to the affirmation in the Eighties of the model of commercial radio, influenced by the centrality of the television and the commercials. The evolution of free radios contributes to redefine the audio-visual landscape of the two countries, causing the end of the public monopoly of the radio and TV broadcast. Free radios, expressing the point-of-new of political, cultural and religious groups of local communities, represented a moment of opening and democratization of the media sector and of widening of spaces of the public sphere. Although these objectives in the Eighties, thanks also to a changed political, social and economic frame, were substituted by the affirmation of the music radios, communitary radios, which favored non-profit forms of communication of proximity, constituted the direct heir of free radios. Despite they occupied a reduced space in the media system of the two countries, they proved the social importance of alternative and local means of communication, with respect to the radiophonic contents and the organization, partially anticipating certain features of interactivity which will be recovered years later with the rise of the web-radios

Full textAbstract:
Acidification of low acid vegetables reduces their pH level to below 4.5 thereby facilitating their processing below 100 degrees Celsius, thus reducing thermal damage, and yielding better product quality. We sought to determine the acidification kinetics of turnip and radish in acetic or citric acid solutions, specifically the time for the treated tissue to reach pH 4.5, and the concurrent percent acidity of the tissue. The two vegetables' response to acidification with citric acid were compared. Experiments followed a central composite rotatable design, with three process variables (temperature, acid concentration and sample: solution ratio), each at five levels. All process variables showed significant effects (P ≤ 0.05) on both time to pH 4.5 and concurrent tissue acidity. Higher acid concentration, temperature or solution: sample ratio resulted in a shorter response time, and higher sample acidity. Optimum processing conditions (shortest time to reach pH 4.5) and the corresponding acidity were determined using a response surface methodology. This acidification process was successfully completed in practice.<br>L'acidification de légumes hypoacides réduit leur pH en dessous de 4.5, facilitant ainsi leur transformation à des températures n'excédant pas 100degrees celsius, réduisant les dommages thermiques, et donnant un produit de plus grande qualité. Nous avons étudié la cinétique d'acidification avec acide acétique ou acide citrique de morceaux de navet ou de radis, en particulier le temps requis pour que les tissues atteignent un pH de 4.5, ainsi que le pourcentage d'acidité à ce moment. La réponse des deux légumes à une acidification par acide citrique fut comparée. Les expériences suivirent un plan central composé rotatif avec trois variables de transformation (température, teneur en acide, et rapport échantillon:solution), chacun à cinq niveaux. Toutes les variables de transformation eurent un effet significatif (P ≤ 0.05) sur le temps pour atteindre un pH de 4.5, ainsi que l'acidité des tissus à ce moment. Une concentration en acide, température, ou rapport échantillon:solution plus élevé donna un temps de réponse plus court, et une acidité du tissus plus élevé. Les conditions de transformation idéales (temps le plus court pour atteindre pH = 4.5) et l'acidité correspondante des tissus, furent déterminés grâce à une méthode de surface de réponse. Cette transformation par acidification fût mise en pratique.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>Este trabalho apresenta o estudo do escoamento transiente em difusores radiais com fronteira móvel alimentados axialmente. O problema é resolvido acoplando-se a modelagem do fluido à dinâmica do movimento da palheta. Admite-se o comportamento Newtoniano para o fluido de trabalho (ar). O escoamento é considerado incompressível, laminar e isotérmico numa geometria axisimétrica. As equações de conservação são resolvidas pelo método dos volumes-finitos utilizando-se um código numérico comercial, o FLUENT, adaptado de modo a permitir que o posicionamento da fronteira móvel faça parte da solução do problema. Analise-se os casos de movimentação súbita imposta à palheta e de fluxo mássico de alimentação periódica. Resultados do comportamento temporal da força axial do fluido sobre a palheta são apresentados. Determina-se também o campo de geração de entropia para o escoamento bem como sua variação para diversos instantes de tempo.<br>This work presents the study of unsteady flow in a axially fed radial flow between parallel disks on a situation in which the frontal disk can move. The problem is solved coupling the fluid flow modeling and the valve dynamics movement. The fluid (air) is assumed to have a Newtonian behavior. The flow is incompressible, laminar and isothermal in an axisymmetric geometry. The governing equations are solved by finite volume methodology using a commercial software, FLUENT, which have been modified to admit boundary movement as part of the solution. The flow characteristics presented herein relate to situations where: I. the frontal disk is suddenly moved to a new location and ii. prescribed mass flux at the inlet orifice. Results for the behavior of the axial force in the frontal disk can be seen. Another important parameter analyzed is the entropy generation and its time variation.

Full textAbstract:
This thesis presents a performance evaluation system for cognitive radio. It considers per-
formance as a complex, multi-dimensional function. Typically such a function would take
some record of actions as an argument; however, a key contribution of this work is the
addition of background information to the domain of the performance function. Including
this information generalizes the performance function across many radios and applications,
with the additional cost of complicating the domain. Thus the presented evaluation system
organizes the domain information into sets. These sets are divided into two categories, one
capturing necessary information that is external to the radio and on capturing necessary
information that internal to the radio. These categories highlight the fact that neither the
true actions nor the true performance is directly observable at the onset of evaluation. This
arises because a cognitive radio can only express its actions in terms of the available knobs
and meters, which together form the radioâ s language. Some understanding of this language
and its limitations is required to fully understand the radioâ s expression of its actions. This
parallelism of actions and performance suggests implementing the evaluation method as a
composite form of the performance function. The composite performance function is made
up of two sub-functions, one of which producing action information and one of which pro-
ducing performance information. Specifically, the first sub-function is used to determine
general measures of the actionsâ influence on performance; these are labeled Measures of Effectiveness. The second sub-function uses these Measures of Effectiveness to determine
application specific performance values, called Measures of Performance. This work covers
both these measures in detail. Each measure is determined as the result of a neural network
based interpolation. This thesis also provides an examination of artificial neural networks
in the scope of performance evaluation. Once these concepts are explored, a walk-through
evaluation is presented. The four phases are the Setup Phase, the Logging Phase, the Train-
ing Phase, and the Evaluation Phase. Each phase is structured to provide the information
necessary to determine the final performance. These phases detail the process of evaluation
and discuss the realization of concepts explored earlier. This work concludes with a compar-
ative evaluation example that proves the worth of the presented approach. A full evaluation
system is outlined by this thesis and the foundational details for the system are explored in detail.<br>Master of Science

This dissertation introduces the concept of an artificial society based on the use of an action based social language combined with the behavior-based approach to the construction of multi-agent systems to address the problem of developing decentralized, self-organizing networks that dynamically fit into their environment. In the course of accomplishing this, social language is defined as an efficient method for communicating coordination information among cognitive radios inspired by natural societies. This communication method connects the radios within a network in a way that allows the network to learn in a distributed holistic manner. The behavior-based approach to developing multi-agent systems from the field of robotics provides the framework for developing these learning networks. In this approach several behaviors are used to address the multiple objectives of a cognitive radio society and then combined to achieve emergent properties and behaviors. This work presents a prototype cognitive radio society.
This society is implemented, using low complexity hardware, and evaluated. The work does not focus on the development of optimized techniques, but rather the complementary design of techniques and agents to create dynamic, decentralized self-organizing networks<br>Ph. D.
