Voorkoms van stres by huismoeders in diens van 'n kinderhuis

Erasmus, Magdalena 11 1900 (has links)
The research posed two questions, namely (a) how much stress, if any, is experienced by house mothers in a childrens' home, and (b) which factors cause such stress. The methodology employed is descriptive research. It covered the total population of ten house mothers in a childres' home. Measuring instruments employed were; the Heimler scale for Social Functioning, the Glazer Stress Control Life Style Questionnaire, the Stress Questionnaire, and a self-formulated questionnaire. The results are as follows: 70% reported average to high stress, but are inclined to deny stress. 30% reported normal stress levels, Possible causes of stress are the work context of the childrens' home, age, period of service, and personality. / Die studie soek antwoorde op twee vrae, naamlik (a) hoeveel sires, indien enige, beleef huismoeders in 'n kinderhuis, en (b) wat veroorsaak sulke sires? Die metode wat gebruik was, is beskrywende navorsing. Die totale populasie van tien huismoeders in die spesifieke kinderhuis is betrek. Die klein omvang maak hierdie studie nie veralgemeenbaar nie. Die volgende meetinstrumente is benut ; die Heimlerskaal vir Maatskaplike Funksionering, die "Glazer Stress Control Life Style Questionnaire'', die "Stress Questionnaire", en 'n selfgeformuleerde vraelys. Die resultate is soos volg: 70% van die huismoeders in die studie vermeld gemiddelde tot hoe mates van stres, maar is geneig om stres te ontken. Dertig persent van die respondente vermeld normale hoeveelhede stres. Moontlike oorsake van sires is aangetoon as: die werkskonteks binne die kinderhuis, ouderdom, tydperk van diens, en persoonlikheid / Social Work / M.A. (Social Work: Mental Health)

A correção e a fundamentação de decisões jurídicas, em bases pragmático-universais, na aplicação do direito de igualdade geral

Leivas, Paulo Gilberto Cogo January 2009 (has links)
A fundamentação e a correção de decisões jurídicas na aplicação do direito de igualdade geral exigem o cumprimento das regras e formas do discurso jurídico fundado em bases pragmático-universais. As viradas lingüística e pragmática, por obra de Frege, Wittgenstein e Peirce, fundaram os alicerces de uma teoria dos atos de fala, de Austin e Searle, de uma teoria da argumentação, de Toulmin, e de uma teoria comunicativa e discursiva da verdade e correção, em Habermas. A ética procedimentalista e cognitivista habermasiana reconstrói o princípio da universabilidade em trajes discursivos. Alexy enuncia um conceito não-positivista e inclusivo da moral fundamentado na pretensão de correção jurídica e argúi a tese do discurso jurídico como caso especial do discurso prático geral. Uma decisão jurídica correta deve ser justificada com base nas regras e formas da justificação interna e externa do discurso. A fundamentação das decisões por meio de argumentos de princípios coloca a exigência da aplicação do preceito da proporcionalidade. As dogmáticas e jurisprudências alemã e brasileira, na aplicação do direito de igualdade geral, utilizam inicialmente uma fórmula da proibição da arbitrariedade ou correlação lógica, da qual resulta uma vinculação fraca do legislador, e passam a adotar uma fórmula baseada na proporcionalidade, com uma vinculação severa do legislador, especialmente quando há tratamento desigual de indivíduos com características especiais elencadas na Constituição. A racionalidade de uma decisão que se utiliza da estrutura da proporcionalidade depende da justificação externa de cada uma das premissas usadas na justificação interna. Há uma relação necessária entre discurso jurídico, proporcionalidade e dogmáticas dos direitos fundamentais. / The justification and correction of legal decisions in the application of general equality principle demands the fullfilment of rules and forms of legal discourse founded on a universal-pragmatic basis. The linguistic and pragmatic turn, by Frege, Wittgenstein, and Peirce, established the foundations of a theory of speech acts, by Austin and Searle, of a theory of reasoning, by Toulmin, and a communicative and discoursive theory on truth and correctness in Habermas. The habermasian proceduralism and cognitivism ethics reconstructs the principle of universability in discoursive ways. Alexy states a non-positivistic and moral inclusive concept of law grounded in the claim to legal correction and argues that the legal discourse must be understood as a special case of general practical discourse. A correct legal decision must be justified on the rules and forms of internal and external justification of discourse. The justification for the decisions by means of arguments of principle sets the demand of applying the partial requirements of proportionality. German and Brazilian legal theory and jurisprudence, in applying the right to general equality, apply initially a formula of prohibition of arbitrary and correlational logic, where there is a weak attachment of the legislature, and start adopting a formula based on proportionality, where there is severe attachment of the legislature, especially in the case of discrimination against individuals with special features listed in the Constitution. The rationality of a decision which uses the structure of proportionality depends on the external justification of each of the premises used in the internal justification. There is a necessary link between proportionality, legal discourse and fundamental rights legal theory.

La fonction administrative contentieuse en Côte d'Ivoire / The contentious administrative function in Ivory Coast

Ambeu, Akoua Viviane Patricia 12 September 2011 (has links)
D’une manière générale, la fonction administrative contentieuse peut être appréhendée comme l’ensemble des juridictions chargées de connaître des litiges résultant de l’activité des autorités administratives. Elle represente l’activité juridictionnelle en matière administrative. Par conséquent, la fonction administrative contentieuse doit s’appréhender tant sous l’angle d’une juridiction, que sous celle de son juge. L’institution d’une fonction administrative contentieuse en Côte d’Ivoire remonte à l’époque coloniale. Cependant, à l’instar de la plupart des ex-colonies françaises, ce n’est qu’au lendemain de l’indépendance en 1960, que la fonction administrative contentieuse ivoirienne s’est affirmée en tant que fonction juridictionnelle autonome à l’égard du système français. La procédure administrative non contentieuse, comme la procédure administrative contentieuse dont il est question dans l’étude ont connu de grands progrès tant en France que dans les pays francophones d’Afrique pour lesquels le système de juridiction administrative comme le droit qu’il vise à contrôler ont longtemps constitué, selon la belle formule de Jean RIVERO, un bon « produit d’exportation » français. La Côte d’ivoire n’échappe pas à ce constat. Aussi l’étude de la fonction administrative contentieuse en Côte d’Ivoire a pour objet de dessiner la physionomie générale de la justice administrative ivoirienne un demi siècle après son institution afin d’en souligner les éléments de permanence ou de changement. / Generally speaking, the contentious administrative function can be arrested as all the jurisdictions asked to know disputes resulting from the activity of the authorities. She represente the jurisdictional activity in administrative subject. Consequently, the contentious administrative functio has to dread as long under the angle of a jurisdiction, that under that of his judge. The institution of a contentious administrative function (office) in Ivory Coast goes back up to the colonial time. However, following the example of most of the French ex-colonies, it is that after the independence in 1960, that the Ivory Coast contentious administrative function asserted itself as autonomous jurisdictional office towards the French system. The not contentious administrative procedure, as the contentious administrative procedure question of which it is in the study knew big progress both in France and in the French-speaking countries of Africa for which the system of jurisdiction administrative as the right at which it aims at checking constituted for a long time, according to the Jean RIVERO's beautiful formula, a voucher " produced by export " French. Ivory Coast does not escape this report. So, the study of the contentious administrative office in Ivory Coast has for object to draw the general face of the Ivory Coast administrative justice half a century after her institution to underline the elements of durability or change.

Nové verze zásobníkových automatů / New Versions of Pushdown Automata

Genčúrová, Ľubica January 2019 (has links)
This thesis investigates multi pushdown automata and introduces their   new modifications based on deep pushdown.  The first modification is Input driven multi deep pushdown automata, which has several deep pushdown lists and the current input symbol determines whether the automaton performs a push operation, a pop operation, an expansion operation or does not touch the stack. The second introduced modification is Regulated pushdown automata by deep pushdown. In addition to ordinary pushdowns, this version contains deep pushdown, which is used to generate the control language. This thesis proves, that the acceptance power of the described variants  is equal to the accepting power of Turing machines.  This thesis also contains view on program realisation of theoretical models, which were described in the theoretical part and introduces a library for the syntax analysis, which is based on it.

Contribution au Diagnotic des Défauts de la Machine Asynchrone Doublement Alimentée de l'Eolienne à Vitesse Variable. / Fault diagnosis of a Doubly Fed Induction Generator (DFIG) in a variable speed wind turbine

Idrissi, Imane 21 September 2019 (has links)
Actuellement, les machines Asynchrones à Double Alimentation (MADA) sont omniprésentes dans le secteur éolien, grâce à leur simplicité de construction, leur faible coût d’achat et leur robustesse mécanique ainsi que le nombre faible d’interventions pour la maintenance. Cependant, comme toute autre machine électrique, ces génératrices sont sujettes aux défauts de différent ordre (électrique, mécanique, électromagnétique…) ou de différents types (capteur, actionneur ou composants du système). C’est pourquoi, il est primordial de concevoir une approche de diagnostic permettant de manière anticipée, de détecter, localiser et identifier tout défaut ou anomalie pouvant altérer le fonctionnement sain de ce type de machine. Motivés par les points forts des méthodes de diagnostic de défauts à base d’observateurs, nous proposons d’une part, dans cette thèse, une approche de détection, localisation et identification des défauts de la MADA d’une éolienne à vitesse variable, à base des observateurs de Kalman, performants et largement utilisés. Les erreurs d’estimation d’état du filtre de Kalman linéaire et de ses variantes non-linéaires, à noter : le Filtre de Kalman Etendu (EKF) et le Filtre de Kalman sans-Parfum (UKF), sont utilisés comme résidus sensibles aux défauts. En vue d’éviter les fausses alarmes et de découpler les défauts des perturbations et des bruits, l’analyse des résidus générés est réalisée par des tests statistiques tels que : Test de Page Hinkley (PH) et Test DCS (Dynamic Cumulative Sum). Pour la localisation des défauts multiples et simultanés, la Structure d’Observateurs Dédiés (DOS) et la Structure d’Observateurs Généralisés (GOS) sont appliquées. De plus, l’amplitude du défaut est déterminée dans l’étape d’identification de défaut. Les défauts capteurs, actionneurs et composants de la MADA, sont traités dans ce travail de recherche. D’autre part, une étude comparative entre les différents observateurs de Kalman, est élaborée. La comparaison porte sur les critères suivants : le temps de calcul, la précision et la vitesse de convergence des estimations. / Actually, the Doubly Fed Induction Generators (DFIG) are omnipresent in the wind power market, owing to their construction simplicity, their low purchase cost and their mechanical robustness. However, as any other electrical machine, these generators are subject to defects of different order (electrical, mechanical, electromagnetic ...) or of different type (sensor, actuator or system). That’s why, it is important to design an effective diagnostic approach, able to early detect, locate and identify any defect or abnormal behavior, which could undermine the healthy operation of this machine On the one hand, motivated by the observer-based fault diagnosis methods strengths, we proposed, in this thesis, a diagnostic approach for the faults detection, localization and identification of the DFIG used in variable speed wind turbine. This approach is based on the use of the efficient and widely used Kalman observers. The state estimation errors of the linear Kalman filter and the non-linear Kalman filters, named: The Extended Kalman Filter (EKF) and the Unscented Kalman Filter (UKF) are used as faults sensitive residuals. In order to avoid false alarms and to decouple faults from disturbances and noises, the faults detection is carried out by the analysis of the residuals generated, by the mean of statistical tests such as: Hinkley Page Test (PH) and DCS Test (Dynamic) Cumulative Sum). For the localization step in case of multiple and simultaneous faults, the Dedicated Observer scheme (DOS) and the Generalized Observer scheme (GOS) are applied. In addition, the fault level is determined in the fault identification step. Sensor faults, actuator and system faults of DFIG, are treated in this research work. On the other hand, a comparative study between the three Kalman observers proposed is performed. The comparison was done in terms of (1) the computation time, (2) the estimation accuracy, and (3) the convergence speed.

Transient Avalanche Oscillation of IGBTs Under High Current

Hong, Tao 11 March 2015 (has links)
Radio frequency oscillations up to several hundreds of MHz were observed during turn-off the high-current conducting IGBTs. They are described in this work as Transient Avalanche oscillations. Other than PETT oscillations that happen in the tail current phase, this oscillation appears during the rise of collector-emitter voltage VCE and during the fall of the collectoremitter current ICE. The turn-off process of IGBTs are investigated with the help of measurements, the circuit- and device-simulations to reveal the working mechanisms of transient high-frequency oscillations. For the first time the Transient Avalanche Oscillation is successfully reproduced with computer simulation, which allows the further investigation on the influences of individual parameters. The participation of IMPATT mechanism in Transient Avalanche oscillation is demonstrated. The interaction between IMPATT mechanism und PETT mechanism during the setting up of depletion region in IGBTs was investigated. Measures to suppress such oscillation are discussed on the levels of chip design, module design and the driver concept. Supplying electron current during critical phase is found to be an effctive method to avoid the dynamic avalanche and the TA-oscillation. / Radio Frequenz Oszillationen bis zu mehreren hundert MHz wurden während des Abschaltens von Hochstrom leitenden IGBTs beobachtet. Sie werden in dieser Arbeit als Transient Avalanche Oscillationen beschrieben. Anders als PETT Oszillationen, die in der Tail-Strom Phase vorkommen, erscheint diese Oszillation während des Anstiegs der Kollektor-Emitter-Spannung VCE und des Fallens des Kollektor-Emitter Stroms ICE. In dieser Arbeit werden die Abschaltvorgänge von IGBTs mit Hilfe von Messungen, Schaltungs- bzw. Device-Simulationen untersucht, um die Wirkungsmechanismen der transient erscheinenden hochfrequenten Oszillationen zu erklären. Es ist erstmals gelungen solche Transient Avalanche Oszillationen mit der Simulation zu reproduzieren und anschließend die Einflüsse einzelner Parameter zu untersuchen. Die Beteiligung des IMPATT Mechanismus an der Transient Avalanche Oszillation wurde nachgewiesen. Die Interaktion von IMPATT und PETT während Aufbau der Raumladungszone im IGBT wurde untersucht. Maßnahmen zur Unterdrückung der Oszillation werden auf den Ebenen von Chip-Design, Modulauslegung und der Treiberschaltung diskutiert. Das Zuführen des Elektrostromes während der kritischen Phase wird als ein effective Methode zur Vermeidung der TA-Oscillation nachgewiesen.

Gottesoffenbarung angesichts des Anderen / Revelation of God in face of the other

Schwarz, Jonathan 11 1900 (has links)
Text in German, summaries in German and English / Diese Masterarbeit handelt von Transzendenzmomenten angesichts des Anderen und nimmt damit Bezug auf einen der einflussreichsten Philosophen der Gegenwart, Emmanuel Levinas. Philosophiegeschichtlich bildet der linguistic turn den Kontext dieses Diskurses. So wird der Wandel im Denken, der mit dem linguistic turn einhergeht, anhand verschiedener philosophischer und theologischer Essays reflektiert und auf das Problem der Gewalt im Prozess des Erkennens hin zugespitzt. In Diskussion mit den Schriften Dietrich Bonhoeffers leistet diese Arbeit hinfort einen Beitrag zum systematisch-theologischen Diskurs über Gottesoffenbarung in zwischenmenschlichen Beziehungen und über Ethik. In Auseinandersetzung mit Levinas und Bonhoeffer baut diese Arbeit eine Brücke zwischen postmodernem, dekonstruktivistischem Denken und der fortwährenden theologischen Aufgabe, Gottes Sein mittels menschlicher Sprache Ausdruck zu verleihen. / This master thesis is about moments of transcendence in face of the other by means of one of the most important philosophers in our days, Emmanuel Levinas. The philosophically based historical context is represented by the term linguistic turn which marks a change of thinking within the 20th century. To outline this change the thesis brings several philosophical and theological essays up for discussion which leads to the problem of power in the process of recognition. Bringing up Dietrich Bonhoeffer’s writings, this research will make a contribution to the systematic-theological discourse about God revealing himself within relationships and about ethics. Furthermore it builds a bridge between postmodern anti-constructivist thinking and the continual theological task of using human language to explore God’s being. / Philosophy, Practical and Systematic Theology / M.

GIS-based Episode Reconstruction Using GPS Data for Activity Analysis and Route Choice Modeling / GIS-based Episode Reconstruction Using GPS Data

Dalumpines, Ron 26 September 2014 (has links)
Most transportation problems arise from individual travel decisions. In response, transportation researchers had been studying individual travel behavior – a growing trend that requires activity data at individual level. Global positioning systems (GPS) and geographical information systems (GIS) have been used to capture and process individual activity data, from determining activity locations to mapping routes to these locations. Potential applications of GPS data seem limitless but our tools and methods to make these data usable lags behind. In response to this need, this dissertation presents a GIS-based toolkit to automatically extract activity episodes from GPS data and derive information related to these episodes from additional data (e.g., road network, land use). The major emphasis of this dissertation is the development of a toolkit for extracting information associated with movements of individuals from GPS data. To be effective, the toolkit has been developed around three design principles: transferability, modularity, and scalability. Two substantive chapters focus on selected components of the toolkit (map-matching, mode detection); another for the entire toolkit. Final substantive chapter demonstrates the toolkit’s potential by comparing route choice models of work and shop trips using inputs generated by the toolkit. There are several tools and methods that capitalize on GPS data, developed within different problem domains. This dissertation contributes to that repository of tools and methods by presenting a suite of tools that can extract all possible information that can be derived from GPS data. Unlike existing tools cited in the transportation literature, the toolkit has been designed to be complete (covers preprocessing up to extracting route attributes), and can work with GPS data alone or in combination with additional data. Moreover, this dissertation contributes to our understanding of route choice decisions for work and shop trips by looking into the combined effects of route attributes and individual characteristics. / Dissertation / Doctor of Philosophy (PhD)
