Este trabalho apresenta um estudo de controladores repetitivos e ressonantes-repetitivos aplicados a fontes ininterruptas de energia (UPSs, do termo em inglês, Uninterruptible Power Supplies). Primeiramente, o desempenho dos controladores repetitivos é analisado a partir das exigências e dos procedimentos de testes definidos pela norma IEC 62040-3. A partir destes resultados, são discutidas as principais causas para o erro de seguimento de um sinal de referência e é avaliado o impacto de metodologias de correção aplicadas na função de transferência do controlador repetitivo. No contexto dos controladores ressonantes-repetitivos duas topologias são analisadas: a primeira é composta por um controlador ressonante sintonizado na frequência fundamental do sinal a ser seguido em paralelo com um controlador repetitivo sintonizado na mesma frequência; a segunda topologia é composta pelo mesmo paralelo entre os controladores ressonante e repetitivo, mas um filtro complementar é adicionado em série com o controlador repetitivo visando alocar a operação de cada controlador em faixas de frequências distintas. Então uma variação do controlador ressonante-repetitivo com filtro é proposta, na qual o filtro é utilizado para corrigir a fase do laço do controlador repetitivo e consequentemente aumentar a magnitude nas frequências de interesse. A partir desta estrutura proposta, uma representação no espaço de estados do sistema em malha fechada é obtida e o projeto do controlador é realizado através da solução de um problema de otimização com restrições na forma de Desigualdades Matriciais Lineares (do inglês, Linear Matrix Inequalities - LMIs). Resultados de simulação utilizando Matlab/PSIM são apresentados para demostrar a melhoria de desempenho do sistema com o controlador proposto. / This work presents a study of repetitive and resonant-repetitive controllers applied to Uninterruptible Power Supplies (UPSs). First, the performance of repetitive controllers is analyzed in terms of requirements and test procedures defined in the IEC 62040-3 standard. From these results the main causes of the reference tracking error are discussed and the impact of correction methodologies applied to repetitive controller transfer function is evaluated. In the context of the resonant-repetitive controllers two topologies are analyzed: the first is composed of a resonant controller tuned to the fundamental frequency of the signal to be followed in parallel with a repetitive controller tuned to the same frequency; the second topology is composed of the same parallel connection between the resonant and the repetitive controllers but a complementary filter is added in series with the repetitive controller aiming to restrict each controller action to different frequency bands. Then a variation of the resonant-repetitive controller with a filter is proposed, in which the filter is used to correct the phase of the repetitive controller loop and consequently increase the magnitude at the frequencies of interest. From this proposed structure, a state space model representing the closed loop system is obtained and the controller design is carried out by the solution of an optimization problem based on LMI (Linear Matrix Inequality) constraints. Simulation results in Matlab/PSIM are presented to demonstrate the improvement on system performance with the proposed controller.

A presente dissertação tem como objetivo apresentar um breve diagnóstico da litigiosidade repetitiva e como o sistema processual propôs alternativas para o seu gerenciamento. Inicialmente, verificou-se que a mudança de paradigma para que o acesso à justiça se tornasse coletivo contribuiu, de forma decisiva, para o aumento da litigiosidade, tornando-se necessária a distinção entre as demandas individuais e coletivas, que passaram a conviver com as demandas repetitivas, e com elas a dividir os mesmos instrumentos processuais, adaptando-os diante da ausência de um microssistema processual próprio. Neste contexto, buscou-se analisar os principais aspectos das ações coletivas, com ênfase naqueles que se apresentaram como óbices à sua eficiência em resolver os conflitos de massa, destacando-se a inexistência de litispendência entre as ações coletivas e individuais, a suspensão opcional do processo individual, a legitimação ope legis para a propositura de ações coletivas, a coisa julgada erga omnes secundum eventum probationis ou secundum eventum litis e as razões que levaram à proibição do uso das ações coletivas quanto a matérias naturalmente candidatas à litigiosidade repetitiva. Paralelamente às ações coletivas, verificou-se que o sistema também buscou gerenciar as demandas repetitivas através de mecanismos processuais, ao proporcionar técnicas de julgamentos que pudessem gerar efeitos a múltiplas demandas individuais que tratassem da mesma controvérsia fática ou jurídica, com o intuito de consolidar a jurisprudência, mas também acelerar os julgamentos, de modo a atingir os vetores valorativos da igualdade, efetividade e segurança jurídica. Buscou-se ainda, contextualizar a questão em uma perspectiva de direito comparado, apresentando as novas técnicas processuais que também surgiram como alternativas às ações coletivas, especificadamente o instituto de origem alemã, que inspirou o Incidente de Resolução de Demandas Repetitivas no Projeto do Novo Código de Processo Civil brasileiro, o Musterverfahren, assim como outros paradigmas nos sistemas norte-americano (Class Actions), inglês (Group Litigation Order), italiano (Azione Collettiva Risarcitoria) e português (Regime Processual Experimental).Por fim, buscou-se apresentar os principais aspectos do Incidente de Resolução de Demandas Repetitivas, enquanto novo instrumento processual que surge como mais uma tentativa de conter o avanço da litigiosidade de massa que sobrecarrega o Poder Judiciário. / The instant dissertation aims to present a brief diagnosis of repetitive litigation, and of how the civil procedure system proposed alternatives to contain it. At first, it was possible to verify that a change to paradigm in order to make the access to justice collective decisively contributed to an increase in litigation, which made the distinction between individual and collective claims necessary, once they coexisted with repetitive claims and shared the same procedural instruments, adapting them in view of the absence of an own procedural micro system. Hence, this study was intended to analyze the main aspects of collective lawsuits, emphasizing the ones presented as obstacles to its efficiency to solve mass conflicts, and highlighting the absence of lis pendens among collective and individual lawsuits, the optional suspension of the individual lawsuit, the ope legis legitimacy to file collective lawsuits, the res judicata erga omnes secundum eventum probationis or res judicata secundum eventum litis and the reasons which led to the prohibition to use collective lawsuits concerning matters naturally prone to repetitive litigation. In addition to collective lawsuits, it was possible to verify that the system also sought to manage repetitive claims through procedural mechanisms, while providing techniques for judgment, which could have effects on multiple individual claims concerning the same legal or factual controversy, with the aim of consolidating precedents, in addition to expediting the decisions, in order to attain equality, effectiveness and legal certainty. Furthermore, this work sought to contextualize the issue within a comparative law perspective, presenting the new procedural techniques which have also arisen as alternatives to collective lawsuits, specifically the German institute Musterverfahren - which inspired the Incidental Motion to Settle Repetitive Litigation (Incidente de Resolução de Demandas Repetitivas) in the Project for the New Brazilian Civil Procedure Code, as well as other paradigms in the North American (Class Actions), British (Group Litigation Order), Italian (Azione Collettiva Risarcitoria ) and Portuguese (Regime Processual Experimental) systems. Finally, this work sought to present the main aspects of the Incidental Motion to Settle Repetitive Litigation (Incidente de Resolução de Demandas Repetitivas), as a new procedural instrument arising as an additional attempt to contain the increase of the mass litigation that burdens the Judiciary.

O Incidente de Resolução de Demandas Repetitivas foi criado pelo Código de Processo Civil de 2015, com expectativa de prestigiar os princípios da segurança jurídica, isonomia e celeridade processual, impactando na melhora ao acesso à justiça. Diante disso, esse estudo visa a examinar se o IRDR é realmente compatível com os princípios processuais constitucionais apontados e se, de outro lado, não afronta outros princípios igualmente de alçada constitucional, verificando-se se este instrumento está apto a funcionar como uma verdadeira ferramenta capaz de contribuir para o desenvolvimento no Estado Democrático de Direito, considerando a necessidade de se expandir as liberdades individuais, aqui alinhadas ao acesso a uma ordem jurídica íntegra, estável e coerente, mas que respeite as garantias imprescindíveis ao devido processo. Nesse contexto, propõe-se uma sistematização do incidente, a partir das disposições pelo Código de Processo Civil, em cotejo com a teoria desenvolvida sobre o instituto, bem como com a análise de dados empíricos, coletados nos autos, acórdãos, andamentos e demais informações referentes a incidentes já julgados por diversos tribunais. Assim, dialogando teoria e prática, propõe-se a melhor compreender o contexto e a sistemática do IRDR, buscando estabelecer uma leitura crítica, mas que contribua para as discussões e para o próprio aprimoramento da aplicação do incidente. / The Incident of Resolution of Repetitive Demands was created by the Civil Procedure Code of 2015, with the expectation of respecting the principles of legal certainty, isonomy and celerity of procedure, impacting on the improvement of justice access. Therefore, this study aims to examine whether the IRDR is actually compatible with the constitutional mentioned procedural principles and if, on the other hand, it does not affront other equally constitutional principles, verifying if this instrument is able to function as a real tool capable of contributing to development in the Democratic State of Law, considering the need to expand individual freedoms, here aligned with access to an integral, stable and coherent legal order, but respecting the guarantees indispensable to due process. In this context, it is proposed to systematize the incident, based on the provisions of the Civil Procedure Code, in conjunction with the theory developed about the institute, as well as with the analysis of empirical data collected in the process, decisions, reports and other informations related of incidents already tried by various courts. Thus, discussing theory and practice, it is proposed to better understand the context and systematics of the IRDR, seeking to establish a critical reading, but that contributes to the discussions and to the improvement of the application of the incident.

Les connaissances actuelles de la physiopathologie de la migraine ne permettent pas encore de déterminer avec exactitude le processus pathologique à lorigine de lactivation du système trigémino-vasculaire conduisant à la céphalée migraineuse. Certains arguments sont en faveur danomalies fonctionnelles du cortex cérébral à même denclencher le processus de la crise de migraine. Parmi ces anomalies, une hypersensibilité sensorielle a été décrite de longue date et a conduit à un important travail en neurophysiologie clinique. Ainsi lutilisation des techniques de potentiels évoqués a abouti à divers résultats dont le plus reproductible consiste en un déficit dhabituation des réponses évoquées corticales lors de stimulations sensorielles répétées chez les migraineux en période intercritique. Comprendre lorigine du déficit dhabituation retrouvé chez les migraineux devrait permettre de préciser le rôle du cortex cérébral dans la cascade dactivation menant à la crise de migraine. Nous avons utilisé la stimulation magnétique transcrânienne répétitive (SMTr) chez les migraineux afin de moduler lexcitabilité des cortex visuel et moteur, en enregistrant ses effets respectivement sur les potentiels évoqués visuels et moteurs. La SMTr a ainsi permis détudier lorigine du déficit dhabituation des potentiels évoqués corticaux retrouvé en période intercritique chez les migraineux. Ce déficit dhabituation des réponses corticales semble provenir dun niveau réduit de préactivation corticale mais également dune activité réduite des interneurones inhibiteurs corticaux. Par ailleurs, ce déficit dhabituation ne semble pas être un élément pathogénique prépondérant dans la mesure où sa seule présence chez les sujets sains ne permet pas den faire des migraineux. Il pourrait correspondre soit à un épiphénomène, soit à un des éléments étiopathogéniques de la migraine, au même titre que la prédisposition génétique, les troubles du métabolisme mitochondrial, Il est vraisemblable que le poids relatif de chacun de ces éléments étiopathogéniques participe à lhétérogénéité des migraines.

Die Gattung Beta gehört zur Familie der Chenopodiaceae und wird in die vier Sektionen Beta, Corollinae, Nanae und Procumbentes unterteilt, wobei die Zuckerrübe der Sektion Beta zugeordnet wird. Aus dem Genom der Zuckerrübe und verwandter Wildarten konnten bereits eine Vielzahl von repetitiven DNA-Familien kloniert und untersucht werden. Mit der monosomen Fragmentadditionslinie PRO1 stand eine Chromosomenmutante zur Verfügung, die neben den 18 B. vulgaris-Chromosomen ein Chromosomenfragment der Wildrübe Beta procumbens enthält. Da dieses als Minichromosom bezeichnete Fragment mitotische Stabilität aufweist, muss es ein funktionelles Centromer besitzen, das auch im genetischen Hintergrund von Beta vulgaris aktiv ist. Mit der Erstellung einer BAC (bacterial artifical chromosome)-Bank von PRO1 wurde die molekulare Charakterisierung von Ty3-gypsy-Retrotransposons eines einzelnen Wildrüben-Centromers möglich. Die für die Wildrübe Beta procumbens spezifischen Satellitenrepeats pTS5 und pTS4.1 dienten der Selektion von BACs aus der Centromer-Region des PRO1-Minichromosoms. Die Identifizierung eines unikalen genomischen Locus, mit einer Verschachtelung von zwei nicht homologen LTR-Retrotransposons, ermöglichte die gerichtete Isolation der LTR-Retrotransposons Beetle1 und Beetle2. Das Retrotransposon Beetle1 hat eine Gesamtlänge von 6736 bp und wird von LTR-Sequenzen begrenzt, die eine Länge von 1091 bp (5’-LTR) bzw. 1089 bp (3’-LTR) aufweisen. Das LTR-Retrotransposon Beetle2 weist mit 6690 bp eine ähnliche Gesamtlänge wie Beetle1 auf. Es wird von deutlich kürzeren LTR-Sequenzen mit einer Länge von 774 bp begrenzt. Aufgrund der Reihenfolge der Polyproteingene lassen sich Beetle1 und Beetle2 in die Gruppe der Ty3-gypsy-Retrotransposons (Metaviridae) einordnen. Beide Retrotransposon-Familien besitzen ein einziges offenes Leseraster (open reading frame; ORF) mit fusionierten gag- und pol-Genen. Datenbankrecherchen zeigten hohe Homologien von Beetle1 und Beetle2 mit den centromerischen Ty3-gypsy-Retrotransposons CRM aus Zea mays, CRR aus Oryza sativa und cereba aus Hordeum vulgare. Diese centromerischen Retrotransposons (CRs) sind in den Poaceae stark konserviert und stellen neben Satellitenrepeats eine hochabundante Sequenzklasse der Centromere der Süßgräser dar. Da sie im 3’-Bereich des gag-pol-Polyproteins eine Chromodomäne aufweisen, werden sie der eigenständigen Gruppe der Chromoviren zugeordnet. Chromodomänen sind zur Bindung von Proteinen und DNA befähigt und spielen eine wichtige Rolle in der Chromatin-Modifikation und der Bildung von Heterochromatin-Regionen. Beetle1 und Beetle2 besitzen Motive einer Chromodomäne, die vermutlich für eine gerichtete Transposition in die Centromer-Region verantwortlich ist. Neben der geringen Divergenz von Beetle1- und Beetle2-Sequenzen sowohl im Genom von Beta procumbens als auch in den anderen Arten der Sektion Procumbentes spricht auch das junge Alter von 100 000 bis 350 000 Jahren und die Transkriptionsaktivität für eine Einordnung dieser Ty3-gypsy-Retrotransposons in die Gruppe der Chromoviren. Sowohl die Southern-Hybridisierung als auch die Fluoreszenz-in situ-Hybridisierung zeigten, dass Beetle1 und Beetle2 nur für die Sektion Procumbentes spezifisch sind und dort in hoher Kopienzahl vorkommen. Untersuchungen mit methylierungssensitiven Restriktionsendonukleasen veranschaulichten den hohen Grad an Cytosin-Methylierung von Beetle1 und Beetle2.

Master of Science / Department of Architectural Engineering and Construction Science / Sutton F. Stephens / Cold-formed steel has become a preferred building material for structural farming in many different types of structures, commonly for repetitive members such as floor joists, roof rafters, roof trusses and wall studs. For wood framed structures with repetitive members, a repetitive member factor increases the allowable bending stress from 1.00 to 1.50 times the reference design value, depending on both the type of material and the type of load. Currently, however, the bending strength of cold-formed steel repetitive members is not permitted to be increased, even though the method of framing is quite similar to that of wood except for the material properties. Typical light-frame wood construction consists of floor, roof, and wall systems, each with repetitive members connected by sheathing. A repetitive system is one of at least three members that are spaced not farther apart than 24-inches. These members must also be joined by a load distributing element adequate to support the design load. The behavior of the individual members, then, is affected by inclusion into this system. Additionally, the connected sheathing increases the bending capacity of bending members due to both composite action and load sharing. Composite action is a result of T-beam-like action between the repetitive member and connected sheathing, but is limited by nail slippage in the connection. Secondly, due to differential deflection between the members, sheathing is also able to distribute loads from weaker, more flexible members to the more rigid and stronger members. This effect is known as load-sharing. The same general principles of repetitive use should apply to cold-formed steel due to its similarity to wood construction. Accordingly, this paper conducts a preliminary study of the effects of both composite action and load-sharing in cold-formed steel assemblies and subsequently recommends using a repetitive member factor for cold-formed steel members.

Literature Review: Anhedonia, the loss of interest or pleasure in usually pleasurable activities, is a core symptom of depression and is associated with a reduction in positive affect (PA). Repetitive negative thought (RNT) is implicated in the development and maintenance of psychiatric disorders. It has been hypothesised that RNT causally contributes to anhedonia. The aim of this review was to explore this relationship to answer two questions: Is there a relationship between RNT and anhedonia? Does RNT causally contribute to anhedonia? Review inclusion criteria were: studies using standardised measures to report a relationship between RNT and anhedonia or reduced PA. Results suggest that cross-sectional and longitudinal studies identify a relationship between RNT and anhedonia. Preliminary evidence from experimental studies shows that RNT causally contributes to anhedonia. Limitations within the field are that anhedonia is rarely measured directly or behaviourally. Future research is warranted to explore the relationship between RNT and anhedonia with a particular focus on direct and behavioural measures of anhedonia. Empirical Paper: It is hypothesised that repetitive negative thought (RNT) causally contributes to anhedonia. There is cross-sectional and longitudinal evidence of this relationship, but it has not previously been investigated directly using experimental methods. In the present study, student participants were randomly assigned to an unresolved goal (RNT) manipulation (n = 43) or resolved goal (control) manipulation (n =41) prior to completing a reward sensitivity task. This task has been reliably found to train a response bias towards the stimuli that is differentially positively reinforced, with both depression and self-reported anhedonia associated with a reduced response bias. The unresolved goal versus resolved goal manipulation was effective, with the unresolved condition producing significantly higher levels of RNT during the reward sensitivity task relative to the resolved condition. Inconsistent with study predictions, there was no significant difference between the conditions on response bias, although there were trend findings, which tentatively suggest that RNT may influence anhedonia. Potential accounts for the null findings and future research are discussed.

The current study examined anxiety and its observable correlates in children with Autism Spectrum Disorders (ASD) across a broad range of levels of cognitive functioning that in the past have not been accurately explored. I sought to challenge the assumption that there is a positive linear relationship between anxiety and level of cognitive functioning by including individuals across a broad range of cognitive functioning in my analyses, and by developing a measure (The Somatic Anxiety Scale) appropriate for assessing anxiety symptoms in children with little to no communicative functioning. Sixty-seven parents of children with ASD aged 5 to 12 completed a battery of measures in an online study assessing their child’s anxiety, repetitive behaviours, sensory processing issues, and adaptive functioning. The Somatic Anxiety Scale was significantly correlated with an existing measure of anxiety designed for verbal children (when only highly verbal children were assessed), suggesting that it may provide a foundation to develop a measure of anxiety symptoms in non-verbal individuals. No clear predictive relationship was observed between level of cognitive functioning and anxiety. Both lower and higher-order repetitive behaviours predicted anxiety, although higher-order behaviours were more predictive. Finally, a cluster analysis indicated three patterns of anxious behaviour divided across three categorizations of level of functioning. I suggest that previous assumptions about the relationship between level of cognitive functioning and anxiety may be underestimating the complexity of the relationship and suggest future research to study this relationship further. / Thesis (Master, Psychology) -- Queen's University, 2013-10-30 10:25:56.049
