Στην παρούσα διδακτορική διατριβή, με βάση την ηλεκτρομαγνητική θεωρία,παρουσιάζεται μία μεθοδολογία για τη μοντελοποίηση πολύθυρων κεραιών κατά την κατάσταση εκπομπής και λήψης τους, δύο στοχαστικές μεθοδολογίες για την αξιολόγησή τους κατά τη λειτουργία τους σε συστήματα διαφορισμού λήψης και μία στοχαστική μεθοδολογία για την περίπτωση που αυτές λειτουργούν σε συστήματα πολλαπλών εισόδων πολλαπλών εξόδων.Οι πολύθυρες κεραίες μοντελοποιούνται στις καταστάσεις εκπομπής και λήψης τους χρησιμοποιώντας είτε τον πίνακα διανυσμάτων ενεργών μηκών ή τον πίνακα αποτελεσματικών ενεργών μηκών. Ο πρώτος τρόπος είναι προσαρμοσμένος για ανάλυση με Ζ-παραμέτρους ενώ ο δεύτερος για ανάλυση με S-παραμέτρους.Η αξιολόγηση των πολύθυρων κεραιών κατα τη λειτουργία τους σε συστήματα διαφορισμού επιτυγχάνεται είτε με τη μέθοδο του πίνακα συνδιασποράς ή με μία υβριδική στοχαστική-ηλεκτρομαγνητική μεθοδολογία. Η πρώτη μεθοδολογία έχει χρησιμοποιηθεί αρκετά στη διεθνή βιβλιογραφία, ενώ η δεύτερη προτείνεται στην παρούσα διατριβή. Και οι δύο μέθοδοι λαμβάνουν υπόψη τους τόσο τις χαρακτηριστικές ιδιότητες των κεραιών όσο και τις ιδιότητες του περιβάλλοντος διάδοσης.Η αξιολόγηση των πολύθυρων κεραιών κατα τη λειτουργία τους σε συστήματα πολλαπλών εισόδων πολλαπλών εξόδων επιτυγχάνεται χρησιμοποιώντας μία γενική μεθοδολογία που βασίζεται σε βασικές αρχές ηλεκτρομαγνητισμού και κυκλωματικής ανάλυσης. Η συγκεκριμένη μεθοδολογία είναι προσαρμοσμένη για ανάλυση με S- παραμέτρους αλλά μπορεί να επεκταθεί και για ανάλυση με Ζ-παραμέτρους. Παρουσιάζεται, επιπλέον, η εφαρμογή της μεθοδολογίας σε κεραίες οι οποίες έχουν κοινό κέντρο φάσης. / Ιn this thesis a method for modeling multi-port antenna structures at both their transmitting and receiving operational modes and methods for their performance evaluation when operating in diversity and MIMO systems is demonstrated under the perspective of electromagnetics combined with stochastic analysis. The method for modeling multi-port antenna structures at both their transmitting and receiving operational modes is achieved using either the effective length matrix or the realized effective length matrix. The former way is convenient for Z-parameter analysis while the latter for S-parameter analysis. Two stochastic methodologies for the performance evaluation of diversity systems are presented. The first one is based on the covariance matrix of the received signals and has been used by many researchers worldwide. The second one, which has been developed in this thesis, combines electromagnetic modeling of multi-port antennas’ the reception mode with a stochastic model. A stochastic methodology for the performance evaluation of MIMO systems is also presented. The methodology has been developed in this thesis in order to be used for Sparameter analysis. Moreover this methodology is applied to model multiport antenna systems with common phase center.

Master work deals with the measurement of fluid flow (particularly air) pipe, with orifice and multiport averaging probe. The theoretical part is followed by practical, which verifies the properties of the measured system. In a next part of semestral work are verifies the properties of multiport averaging probes Vavra s.r.o. MQS-011 and Rosemount Annubar 485. Measured values from probes are compared.

It is seen that this issue is of paramount importance, since the introduction of the term reasonable in adjudication as a constitutional principle brings a commitment of the state to the citizen in order to give greater effectiveness to the process and ensure the fundamental right of access to justice . To reach this conclusion, we used literature search, legislative, administrative and judicial, with theoretical frameworks in several authors, starting with Barroso and converging into arguments which support the applicability of this Amendment, from a historical analysis (ontological) and evaluative (axiological). Then, there was the jurisprudential research on the subject in the main Brazilian courts, celing in the Superior Courts, to then undertake a comparative analysis with the bibliographic material. The importance of the principle stands out as a precondition for full citizenship in Democratic States of law, guaranteeing citizens the realization of their rights are constitutionally guaranteed. The principles of speed and duration of the process should be applied with observation of the principles of reasonableness and proportionality, ensuring that the process does not extend beyond the reasonable deadline, nor will compromise other principles such as defense and full of contradiction. It is certain, however - and for the benefit of people who need an effective justice - that Constitutional Amendment 45/04 (which among other novelties inserted explicitly the principle of reasonable duration of the process) seeks to reform the judiciary means for ensuring that become more agile and stronger, which is essential in a society like ours so devoid of enforcing rights to citizens. The current concern guiding procedures and the right to a speedy and effective duration of the process, summons us to an analysis of the role of the National Council of Justice - CNJ and programs, like the "Update" in the Goiás FONAJE and Process Judicial E-EO, as these tools, among others, that result in responses necessary for today's social and economic problems. On the other hand, alternative means of conflict resolution, complementary to the formal judicial process, even because of its informality and adaptability, suggest the solution many cases, in the antechambers of mediation and conciliation (consensus building). It would be a paradigm shift, erecting alternative model judicialization as a counter-archetype adjunct to mitigate the culture of demanda.Daí the idea of the Courts or adoptive Forums Multiport as promoting integrative means for the settlement of disputes. The traditional process would be for more complex cases, adapting to the American experience to our reality, given the similarity. / O presente estudo tem por objeto a analise da Emenda Constitucional nº 45/2004, que inseriu o princípio da razoável duração do processo dentro das garantias fundamentais asseguradas a cada indivíduo e está insculpido no inciso LXXVIII, do art. 5º, da Constituição Federal de 1988, na perspectiva de que a tutela jurisdicional deve ser efetiva, tempestiva e adequada. Vê-se que tal questão é de suma importância, vez que a introdução do prazo razoável na prestação jurisdicional como princípio constitucional traz um compromisso do Estado para com o cidadão a fim de dar maior efetividade ao processo e garantir o direito fundamental de acesso à Justiça. Para chegar a essa conclusão, utilizou-se pesquisa bibliográfica, legislativa, administrativa e jurisprudencial, com marcos teóricos em diversos autores, iniciando-se com Barroso e confluindo para argumentos que sirvam de suporte à aplicabilidade da referida Emenda, a partir de uma análise histórica (ontológica) e valorativa (axiológica). Em seguida, foi feita a pesquisa jurisprudencial relativa ao tema nos principais tribunais brasileiros, máxime nos Tribunais Superiores, para então proceder a uma análise comparativa com o material bibliográfico. A importância do princípio se destaca como pressuposto para o exercício pleno da cidadania nos Estados Democráticos de Direito, garantindo aos cidadãos a concretização dos direitos que lhes são constitucionalmente assegurados. Os princípios da celeridade e da duração do processo devem ser aplicados com observação aos princípios da razoabilidade e da proporcionalidade, assegurando que o processo não se estenda além do prazo razoável, nem tampouco venha comprometer outros princípios como o da plena defesa e do contraditório. É certo, porém e para benefício da população que necessita de uma justiça efetiva que pela Emenda Constitucional 45/04 (que dentre outras novidades inseriu expressamente o princípio da duração razoável do processo) procura-se reformar o Poder Judiciário garantindo meios para que se torne mais ágil e fortalecido, o que é fundamental em uma sociedade como a nossa tão carente da efetivação de direitos aos cidadãos. A preocupação atual que norteia os procedimentos e o direito a uma rápida e eficaz duração do processo, nos convoca a uma análise do papel do Conselho Nacional de Justiça CNJ e de Programas, a exemplo do Atualizar , em Goiás do FONAJE e do Processo Judicial Eletrônico PJE, estes como ferramentas, dentre outras, que resultam em repostas necessárias aos problemas sociais e econômicos hodiernos. De outro lado, os meios alternativos de solução dos conflitos, complementares ao processo judicial formal, em razão mesmo da sua informalidade e adaptabilidade, sugerem a solução de muitos casos, nas antecâmaras de mediação e conciliação (consensus building). Seria uma mudança de paradigmas, erigindo alternativa ao modelo de judicialização como um contra-arquétipo coadjuvante para mitigar a cultura da demanda.Daí a idéia adotiva dos Tribunais ou Fóruns Multiportas, como promoção de meios integrativos para a solução das controvérsias. O processo tradicional ficaria para os casos de maior complexidade, adaptando-se a experiência norteamericana à nossa realidade, dada a similitude.

Les travaux menés dans cette thèse concernent les problèmes d'ordonnancement sur des plates-formes de calcul dynamiques et hétérogènes et s'appuient sur le modèle de communication "multi-port" pour les communications. Nous avons considéré le problème de l'ordonnancement des tâches indépendantes sur des plates-formes maîtres-esclaves, dans les contextes statique et dynamique. Nous nous sommes également intéressé au problème de la redistribution de fichiers répliqués dans le cadre de l'équilibrage de charge. Enfin, nous avons étudié l'importance des mécanismes de partage de bande passante pour obtenir une meilleure efficacité du système. / The results presented in this document deal with scheduling problems on dynamic and heterogeneous computing platforms under the "multiport" model for the communications. We have considered the problem of scheduling independent tasks on master-slave platforms, in both offline and online contexts. We have also proposed algorithms for replicated files redistribution to achieve load balancing. Finally, we have studied the importance of bandwidth sharing mechanisms to achieve better efficiency.
