Abstract:

The problem of identifying connections between nodes in a network model is of fundamental importance in the analysis of brain networks because each node represents a specific brain region that can potentially be connected to other brain regions by means of functional relations; the dynamical behavior of each node can be quantified by adopting a correlation measure among time series. In this contest, the whole set of links between nodes in a network can be represented by means of an adjacency matrix with high dimension, that can be obtained by performing a huge number of simultaneous tests on correlations. In this regard, the Thesis has dealt with the problem of multiple testing in a Bayesian perspective, by examining in depth the “Bayesian False Discovery Rate” (FDR), already defined in Efron, and by introducing the “Bayesian Power” (BP). The behavior of the FDR and BP estimators has been analyzed both with asymptotic theory and with Monte Carlo simulations; furthermore, it has been investigated the robustness of the proposed estimators by simulating specific pattern of dependencies among the p-values associated to the multiple comparisons. Such a multiple testing approach, that allows to control both FDR and BP, has been applyied to a dataset provided by the Milan Center for Neuroscience (NeuroMi). Once selected a sample of 70 participants, classified properly into young subjects and elderly subjects, subject by subject network models have been constructed in order to verify two alternative theories about changes in the pattern of functional connectivity as time goes by, namely the de-differentiation hypothesis versus the localization hypothesis. This objective has been achieved by selecting some proper network measures in order to verify the original hypotheses about the pattern of functional connectivity in the elderly’s group and in the group of young subjects, and by constructing some ad-hoc measures.

A presente dissertação tem por objetivo propor e avaliar cinco técnicas de detecção de ruídos impulsivos para a melhoria da transmissão digital de dados via redes de energia elétrica (do inglês, Power Line Communications) (PLC). As técnicas propostas contemplam a detecção de ruídos impulsivos no domínio do tempo discreto, no domínio da transformada wavelet discreta (do inglês, Discrete Wavelet Transform) (DWT) e no domínio da transformada discreta de Fourier (do inglês, Discrete Fourier Transform) (DFT). Tais técnicas fazem uso de métodos de extração e seleção de características, assim como métodos de detecção de sinais baseados na teoria de Bayes e redes neurais. Análises comparativas explicitam as vantagens e desvantagens de cada uma das técnicas propostas para o problema em questão, e ainda indicam que estas são bastante adequadas para a solução do mesmo.
This dissertation aims to propose and evaluate ﬁve techniques for impulsive noise detection in order to improve digital communications through power line channels. The imput signals for the proposed detection techniques are impulsive noise signals on discrete-time domain, on the Discrete Wavelet Transform domain and on the Discrete Fourier Transform domain and it makes use of feature extraction and selection techniques, as well as detection techniques supported on Bayes Theory and Multi-layer Perceptron Neural Networks. Comparative analysis show some advantages and disadvantages of each proposed technique and the relevance of them to solve the impulsive noise detection problem.

Abstract:

Les travaux présentés dans cette thèse concernent l'analyse statistique de cas particuliers du processus de Cox. Dans une première partie, nous proposons une synthèse des résultats existants sur le processus power-law (processus d'intensité puissance), synthèse qui ne peut être exhaustive étant donné la popularité de ce processus. Nous considérons une approche bayésienne pour l'inférence des paramètres de ce processus qui nous conduit à introduire et à étudier en détails une distribution que nous appelons loi H-B. Cette loi est une loi conjuguée. Nous proposons des stratégies d'élicitation des hyperparamètres et étudions le comportement des estimateurs de Bayes par des simulations. Dans un deuxième temps, nous étendons ces travaux au cas du processus d’intensité exponentielle (exponential-law process). De la même façon, nous définissons et étudions une loi conjuguée pour l'analyse bayésienne de ce dernier. Dans la dernière partie de la thèse, nous considérons un processus auto-excité qui intègre une covariable. Ce travail est motivé, à l'origine, par un problème de fiabilité qui concerne des données de défaillances de matériels exposés à des environnements sévères. Les résultats sont illustrés par des applications sur des données d'activités orageuses collectées dans deux départements français. Enfin, nous donnons quelques directions de travail et perspectives de futurs développements de l'ensemble de nos travaux
The work presented in this PhD dissertation concerns the statistical analysis of some particular cases of the Cox process. In a first part, we study the power-law process (PLP). Since the literature for the PLP is abundant, we suggest a state-of-art for the process. We consider the classical approach and recall some important properties of the maximum likelihood estimators. Then we investigate a Bayesian approach with noninformative priors and conjugate priors considering different parametrizations and scenarios of prior guesses. That leads us to define a family of distributions that we name H-B distribution as the natural conjugate priors for the PLP. Bayesian analysis with the conjugate priors are conducted via a simulation study and an application on real data. In a second part, we study the exponential-law process (ELP). We review the maximum likelihood techniques. For Bayesian analysis of the ELP, we define conjugate priors: the modified- Gumbel distribution and Gamma-modified-Gumbel distribution. We conduct a simulation study to compare maximum likelihood estimates and Bayesian estimates. In the third part, we investigate self-exciting point processes and we integrate a power-law covariate model to this intensity of this process. A maximum likelihood procedure for the model is proposed and the Bayesian approach is suggested. Lastly, we present an application on thunderstorm data collected in two French regions. We consider a strategy to define a thunderstorm as a temporal process associated with the charges in a particular location. Some selected thunderstorms are analyzed. We propose a reduced maximum likelihood procedure to estimate the parameters of the Hawkes process. Then we fit some thunderstorms to the power-law covariate self-exciting point process taking into account the associated charges. In conclusion, we give some perspectives for further work

Abstract:

Mit der Liberalisierung des Strommarkts, den unsicheren Aussichten in der Klimapolitik und stark schwankenden Preisen bei Brennstoffen, Emissionsrechten und Kraftwerkskomponenten hat bei Kraftwerksinvestitionen das Risikomanagement an Bedeutung gewonnen. Dies äußert sich im vermehrten Einsatz probabilistischer Verfahren. Insbesondere bei regulativen Risiken liefert der klassische, häufigkeitsbasierte Wahrscheinlichkeitsbegriff aber keine Handhabe zur Risikoquantifizierung. In dieser Arbeit werden Kraftwerksinvestitionen und -portfolien in Deutschland mit Methoden des Bayes'schen Risikomanagements bewertet. Die Bayes'sche Denkschule begreift Wahrscheinlichkeit als persönliches Maß für Unsicherheit. Wahrscheinlichkeiten können auch ohne statistische Datenanalyse allein mit Expertenbefragungen gewonnen werden. Das Zusammenwirken unsicherer Werttreiber wurde mit einem probabilistischen DCF-Modell (Discounted Cash Flow-Modell) spezifiziert und in ein Einflussdiagramm mit etwa 1200 Objekten umgesetzt. Da der Überwälzungsgrad von Brennstoff- und CO2-Kosten und damit die Höhe der von den Kraftwerken erwirtschafteten Deckungsbeiträge im Wettbewerb bestimmt werden, reicht eine einzelwirtschaftliche Betrachtung der Kraftwerke nicht aus. Strompreise und Auslastungen werden mit Heuristiken anhand der individuellen Position der Kraftwerke in der Merit Order bestimmt, d.h. anhand der nach kurzfristigen Grenzkosten gestaffelten Einsatzreihenfolge. Dazu wurden 113 thermische Großkraftwerke aus Deutschland in einer Merit Order vereinigt. Das Modell liefert Wahrscheinlichkeitsverteilungen für zentrale Größen wie Kapitalwerte von Bestandsportfolien sowie Stromgestehungskosten und Kapitalwerte von Einzelinvestitionen (Steinkohle- und Braunkohlekraftwerke mit und ohne CO2-Abscheidung sowie GuD-Kraftwerke). Der Wert der Bestandsportfolien von RWE, E.ON, EnBW und Vattenfall wird primär durch die Beiträge der Braunkohle- und Atomkraftwerke bestimmt. Erstaunlicherweise schlägt sich der Emissionshandel nicht in Verlusten nieder. Dies liegt einerseits an den Zusatzgewinnen der Atomkraftwerke, andererseits an den bis 2012 gratis zugeteilten Emissionsrechten, welche hohe Windfall-Profite generieren. Dadurch erweist sich der Emissionshandel in seiner konkreten Ausgestaltung insgesamt als gewinnbringendes Geschäft. Über die Restlaufzeit der Bestandskraftwerke resultiert ab 2008 aus der Einführung des Emissionshandels ein Barwertvorteil von insgesamt 8,6 Mrd. €. In ähnlicher Dimension liegen die Barwertvorteile aus der 2009 von der Bundesregierung in Aussicht gestellten Laufzeitverlängerung für Atomkraftwerke. Bei einer achtjährigen Laufzeitverlängerung ergäben sich je nach CO2-Preisniveau Barwertvorteile von 8 bis 15 Mrd. €. Mit höheren CO2-Preisen und Laufzeitverlängerungen von bis zu 28 Jahren würden 25 Mrd. € oder mehr zusätzlich anfallen. Langfristig erscheint fraglich, ob unter dem gegenwärtigen Marktdesign noch Anreize für Investitionen in fossile Kraftwerke gegeben sind. Zu Beginn der NAP 2-Periode noch rentable Investitionen in Braunkohle- und GuD-Kraftwerke werden mit der auslaufenden Gratiszuteilung von Emissionsrechten zunehmend unrentabler. Die Rentabilität wird durch Strommarkteffekte der erneuerbaren Energien und ausscheidender alter Gas- und Ölkraftwerke stetig weiter untergraben. Steinkohlekraftwerke erweisen sich selbst mit anfänglicher Gratiszuteilung als riskante Investition. Die festgestellten Anreizprobleme für Neuinvestitionen sollten jedoch nicht dem Emissionshandel zugeschrieben werden, sondern resultieren aus den an Grenzkosten orientierten Strompreisen. Das Anreizproblem ist allerdings bei moderaten CO2-Preisen am größten. Es gilt auch für Kraftwerke mit CO2-Abscheidung: Obwohl die erwarteten Vermeidungskosten für CCS-Kraftwerke gegenüber konventionellen Kohlekraftwerken im Jahr 2025 auf 25 €/t CO2 (Braunkohle) bzw. 38,5 €/t CO2 (Steinkohle) geschätzt werden, wird ihr Bau erst ab CO2-Preisen von 50 bzw. 77 €/t CO2 rentabel. Ob und welche Kraftwerksinvestitionen sich langfristig rechnen, wird letztlich aber politisch entschieden und ist selbst unter stark idealisierten Bedingungen kaum vorhersagbar.
Power plant investors face large uncertainties due to ongoing liberalization, climate policy, and long investment horizons. This study provides a probabilistic appraisal of power plant investments within the framework of Bayesian decision theory. A Bayesian influence diagram is used for setting up a discounted cash flow model and analysing the profitability of power plants. As the study explicitly models merit order pricing, the pass-through of random fuel and carbon costs may be analysed. The study derives probabilistic statements about net present values of single investments and company portfolios and explores the sensitivity of profits to variations of select input variables. In the majority of cases, an increase in the price of emission allowances also increases the net present value of existing power plant portfolios. A substantially increased carbon prices also is the prerequisite to diversify power plant portfolios by gas and CCS plants. For the currently prevailing German electricity market, we argue that investors may lack incentives for new investments in fossil generation, a finding that holds true also with implementation of CCS. Our estimates are conservative, as profitability will further deteriorate with the build-up of renewables.

Abstract:

The objective of this study is to compare Bayesian and parametric approaches to determine the best for estimating reliability in complex systems. Determining reliability is particularly important in business and medical contexts. As expected, the Bayesian method showed the best results in assessing the reliability of systems. In the first study, the Bayesian reliability function under the Higgins-Tsokos loss function using Jeffreys as its prior performs similarly as when the Bayesian reliability function is based on the squared-error loss. In addition, the Higgins-Tsokos loss function was found to be as robust as the squared-error loss function and slightly more efficient. In the second study, we illustrated that--through the power law intensity function--Bayesian analysis is applicable in the power law process. The power law intensity function is the key entity of the power law process (also called the Weibull process or the non-homogeneous Poisson process). It gives the rate of change of a system's reliability as a function of time. First, using real data, we demonstrated that one of our two parameters behaves as a random variable. With the generated estimates, we obtained a probability density function that characterizes the behavior of this random variable. Using this information, under the commonly used squared-error loss function and with a proposed adjusted estimate for the second parameter, we obtained a Bayesian reliability estimate of the failure probability distribution that is characterized by the power law process. Then, using a Monte Carlo simulation, we showed the superiority of the Bayesian estimate compared with the maximum likelihood estimate and also the better performance of the proposed estimate compared with its maximum likelihood counterpart. In the next study, a Bayesian sensitivity analysis was performed via Monte Carlo simulation, using the same parameter as in the previous study and under the commonly used squared-error loss function, using mean square error comparison. The analysis was extended to the second parameter as a function of the first, based on the relationship between their maximum likelihood estimates. The simulation procedure demonstrated that the Bayesian estimates are superior to the maximum likelihood estimates and that the selection of the prior distribution was sensitive. Secondly, we found that the proposed adjusted estimate for the second parameter has better performance under a noninformative prior. In the fourth study, a Bayesian approach was applied to real data from breast cancer research. The purpose of the study was to investigate the applicability of a Bayesian analysis to survival time of breast cancer data and to justify the applicability of the Bayesian approach to this domain. The estimation of one parameter, the survival function, and hazard function were analyzed. The simulation analysis showed that the Bayesian estimate of the parameter performed better compared with the estimated value under the Wheeler procedure. The excellent performance of the Bayesian estimate is reflected even for small sample sizes. The Bayesian survival function was also found to be more efficient than its parametric counterpart. In the last study, a Bayesian analysis was carried out to investigate the sensitivity to the choice of the loss function. One of the parameters of the distribution that characterized the survival times for breast cancer data was estimated applying a Bayesian approach and under two different loss functions. Also, the estimates of the survival function were determined under the same setting. The simulation analysis showed that the choice of the squared-error loss function is robust in estimating the parameter and the survival function.

Abstract:

Despite its critical role in counselor training, empirical research on clinical supervision is generally limited (Bernard & Goodyear, 2003; Ellis & Ladany, 2007). This is also applied to an area of power dynamics in supervision. This study tested the relationship between the two aspects of power dynamics; namely, supervisors' power bases (i.e., sources of influencing others) and supervisory styles (i.e., typical ways of shaping supervision), based on the system's approach to supervision model (Holloway, 1995). This research was a correlational design. Students in masters' and doctoral counseling programs were asked to respond to an online questionnaire packet via Survey MonkeyTM. Of those who responded, 492 students who took supervision with professor or doctoral student supervisors constituted the sample. Varied numbers of participants were used for each analysis after missing or extreme data were deleted. Supervisors' usage of power bases and supervisory styles were measured by the adopted version of Interpersonal Power Inventory (Raven, Schwarzwald, & Koslowsky, 1998) and Supervisory Style Inventory (SSI; Friedlander & Ward, 1984), respectively. In part 1, results of factor analyses revealed four first-order power factors and two higher-order power factors (Soft & Harsh). Schmeid-Leiman's (1957) solution was also applied. In part 2, result of correlation analysis in revealed that supervisors' usage of Soft or Soft-type power factor (Idealized Expert) was moderately positively correlated to all three supervisory styles but that usage of Harsh or Harsh-type factors (Compensatory Obligation, Relational Power, & Collaborative Alliance) was only weakly correlated to supervisory styles, for majority of supervisors. Similarly, results of regression analyses revealed that supervisory styles did not significantly predict supervisors' usage of Harsh factor, but both supervisory styles and usage of ix Harsh factor significantly predicted usage of Soft factor at moderate and strong level, respectively. The interpersonally-sensitive styles predicted Soft factor slightly more strongly than the other styles. It was concluded that supervisors who engaged in supervision with any one of three supervisory styles also tended to use more Soft or Soft-type factor when there are disagreements, but rarely used Harsh or Harsh types.

This study aimed at analyzing the mediating power of organizational values in the relation between the power bases and life quality at work. In order to do so, we propose an analysis model that investigates the influence of the organizational values in the relation between the power bases and life quality at work. We counted on the participation of 227 workers of four organizations a public one, philanthropic one and two private ones. The instruments used in order to collect the data were: an organizational values inventory, a scale of perception of the power bases and the scale of perception of life quality at work. The collected data were analyzed with the use of SPSS - Statistical Package for the Social Sciences, version 12.0. The results of the analysis show that only the organizational value conservation mediates the relation between the power bases of legal prerogatives and resources control and life quality at work. Among the biographical values, only the gender influenced life quality at work.

Delivering electrical power to remote military bases can be an expensive and dangerous task. The idea of delivering renewable power to remote military bases through space-based solar power has existed for many years, but has not yet materialized. This research sought to examine existing studies and leverage their findings to determine a systems architecture and subsequent design alternatives that could deliver space-based solar power to a military base in Afghanistan. Three design alternatives were created and were based on the defined systems architecture. The system attributes vary by design alternative, to include transmitter size, rectenna size, power transmitted, mass of components, and number of launches required. The design attributes were weighted accordingly to stakeholder objectives. In turn, the entire design alternative was given a Measure of Effectiveness score. This score was used to determine the most effective design alternative among the designs presented in this research. The result is one of the three designs conclusively meets stakeholder requirements and is more effective than the others, yet further research should be done to improve the design and address other concerns, such as the extremely high cost of the system and the potential environmental and safety issues of the high-power microwave beam.

Abstract:

The purpose of this study was to describe staff nurses' perceptions of their power bases in their work environment. Power, the capacity to set conditions, make decisions and take action that influences others, is an increasingly important issue within the nursing profession. In the nursing literature, nurses have been encouraged to consider the power to influence nursing care as an attainable goal and a necessary element in the change process. Empowering staff nurses may become a strategy for coping with the nursing manpower shortage. However, research about nursing power has focused on the nurse manager and little is written about staff nurses' perception of their power. A grounded theory research design was used to collect and analyze data. Data were collected through interviews of nine staff nurses in a 369 bed British Columbia community hospital. A comparative content analysis was used to analyze the data. The findings showed that the staff nurse participants were able to recognize certain factors in their work environment that impacted on their sense of power. The nature of nurses' work and the communication of information were found to be the most significant factors. The communication of information was perceived to positively influence nurses' sense of power, while the nature of nurses' work was found to limit nurses' sense of power. Nurses' lack of control over client care was found to contribute to a sense of powerlessness and was linked to units using team nursing. The eight power bases outlined in Randolph's framework, were useful as a basis for describing the staff nurses' perceptions of their organizational power bases. The staff nurses studied were found to have the most affinity for referent, expert, information, and connection power bases. These nurses were found to have the least affinity for reward, coercion, legitimate, and resource power bases. Primary nursing was found to enhance legitimate power while team nursing was found to enhance connection power. The source of power most frequently mentioned by the nurse participants was personal power in relation to oneself. This did not fit into Randolph's framework and was not well defined. This has implications for nursing since support for the professional nature of nurses' work was found to strenghthen nurses' sense of personal power. Knowledge about the perceptions described by the subjects in this investigation provides information to assist nurses' to identify power bases that they may not recognize. As well, increased understanding about staff nurses' perceptions of power should enable nursing administration to identify strategies for retaining nurses and enhancing client care.

Reconstituição da trajetória política de Ney Braga, procurando compreender as bases de poder explicativas de sua longa permanência na política. O militar Ney Braga tornou-se uma das maiores expressões do cenário político contemporâneo paranaense. Entra na política nos anos 1950, quando foi prefeito de Curitiba, mantendo-se na cena política durante a democracia populista. Apóia o golpe de Estado de 1964, consolidando seu poder político, e mantém seu exercício político no decorrer do regime autoritário, com alguns momentos de fragilização, quando do governo de Costa e Silva e parte do governo Médici (ambos ligados ao grupo da ala dura do exército). O processo de abertura política vai marcar o declínio político de Ney Braga.

Abstract:

A eletricidade é um insumo cujo impacto nos custos dos serviços públicos municipais varia de acordo com a maneira como ela é utilizada e a forma como é adquirida da empresa fornecedora. A gestão de seu uso resulta em economia e em aprimoramento da eficiência e da qualidade na prestação dos serviços, incluindo a iluminação pública, além de mitigar impactos ambientais e desenvolver ações de orientação da sociedade sobre padrões de consumo eficientes de energia. O setor público representa parcela significativa do consumo final de eletricidade no Brasil, com tendência de aumento, mas identifica-se nas prefeituras municipais potencial de redução do consumo e aumento da eficiência energética. O objetivo deste trabalho é identificar conceitos e estabelecer diretrizes que possam servir de bases para uma política pública de gestão da energia elétrica no âmbito da administração municipal. Este documento relata o desenvolvimento de estudos teóricos e pesquisas empíricas sobre o uso eficiente da energia elétrica em serviços públicos em cidades de diferentes países e analisa os resultados da aplicação de modelos que vão sucessivamente se aprimorando na realidade de municípios da região metropolitana de São Paulo. Conclui que cabe à municipalidade um papel muito mais relevante que o de um mero consumidor institucional de eletricidade, propondo bases para uma intervenção na realidade do município.
Electricity is an input whose impact on the costs of the municipal public services varies according to the manner it is used and to the way it is obtained from the supplying company. The management of its use results in savings and in greater efficiency and quality of the delivered services - including the public lighting - besides, it softens environmental impacts and develops actions to orientate society towards energy-efficient consumption habits. The public sector has a significant share in the electricity final consumption in Brazil, trending to increase, but a room for consumption reduction and increase in energy efficiency can be seen in the municipalities. The purpose of this thesis is to identify concepts and set parameters that can be the basis of a public policy on electrical power management at the ambit of municipality. This paper reports a series of theoretical studies and empirical researches concerning the efficient use of electrical power in public services in cities of different countries and analyses the results reached from the application of models that successively work in the reality of cities from the Sao Paulo metropolitan area. It concludes that the municipality must play a role much more relevant than being a simple institutional electricity consumer, by proposing the basis for an intervention in the municipal reality.

Full text

Abstract:

We introduce a notion of Gröbner reduction of everywhere convergent power series over the real or complex numbers with respect to ideals generated by polynomials and an admissible term ordering. The presented theory is situated somewhere between the known theories for polynomials and formal power series. Our main theorem states the existence of a formula for the division of everywhere convergent power series over the real or complex numbers by a finite set of polynomials. If the set of polynomials is a Gröbner basis then the remainder of that division depends only on the equivalence class of the power series modulo the ideal generated by the polynomials. When the power series which shall be divided is a polynomial the division formula leads to a usual Gröbner representation well known from polynomial rings. Finally, the results are applied to prove the closedness of ideals generated by polynomials in the ring of everywhere convergent power series and to give a very simple proof of the affine version of Serre's graph theorem.

Abstract:

Florida reformed its civil service system with the passage of the Service First Initiative of 2001, resulting in a unique organizational setting by altering the employer-employee relationship, yet little academic research explored the power tactics used by politicians and political appointees in order to gain subordinate compliance in unique organizational environments. Using French and Raven’s bases of social power theory and Raven’s interpersonal power interaction model as the foundation, the primary purpose of this stratified cross-sectional study of politicians and political appointees in Florida was to explore whether certain demographic factors are predictors of the extent to which French and Raven’s “hard” and “soft” power tactics are used. Survey data were collected using the interpersonal power inventory, political predisposition measure, and a self-developed demographic information form from 354 political appointees and state employees and were analyzed using simple multiple linear regression. Findings indicated the usage of the power tactics is consistent Ravens original research with influence agents preferring the soft power tactics over hard. Findings also showed that age and race (notably African American) are statically significant predictors of usage of soft power tactics of expert, referent, informational, the legitimacy of dependency, personal reward and harsh power tactics of personal coercion, legitimacy of reciprocity and equity (p <.05). Positive social change implications resulting from this study include recommendations regarding development of leadership programs to reduce the reliance on the use of harsh power tactics in order to increase organizational and personal outcomes within Service First Initiative organizations.

Cryptography is defined to be the practice and studying of hiding information and is used in applications present today; examples include the security of ATM cards and computer passwords ([34]). In order to transform information to make it unreadable, one needs a series of algorithms. Many of these algorithms are based on elliptic curves because they require fewer bits. To use such algorithms, one must find the rational points on an elliptic curve. The study of Algebraic Number Theory, and in particular, rare objects known as power bases, help determine what these rational points are. With such broad applications, studying power bases is an interesting topic with many research opportunities, one of which is given below. There are many similarities between Cyclic and Dihedral fields of prime degree; more specifically, the structure of their field discriminants is comparable. Since the existence of power bases (i.e. monogenicity) is based upon finding solutions to the index form equation - an equation dependant on field discriminants - does this imply monogenic properties of such fields are also analogous? For instance, in [14], Marie-Nicole Gras has shown there is only one monogenic cyclic field of degree 5. Is there a similar result for dihedral fields of degree 5? The purpose of this thesis is to show that there exist infinitely many monogenic dihedral quintic fields and hence, not just one or finitely many. We do so by using a well- known family of quintic polynomials with Galois group D₅. Thus, the main theorem given in this thesis will confirm that monogenic properties between cyclic and dihedral quintic fields are not always correlative.

Abstract:

This article explores the role of financial intelligence in the context of intelligence studies. Reviewing relevant literature, the field of intelligence studies is divided into a public, and a private sphere, which is directly related to businesses and organizations. Consequently, this context is clarified before financial intelligence could be placed in a theoretical framework and further defined in a content-related way. The recent lack of a useful definition, that addresses several aspects, was emphasized by providing an appropriate explanation of financial intelligence. For illustration purposes, a link to the theory on organizational power (bases of power) is made to show how organizational power can be promoted by financial intelligence. Thus, financially intelligent individuals have good opportunities to increase their expert power and informational power for example. In fact, it is advantageous for both individuals and organizations. Within our line of argumentation, we assume that financial intelligence is a good source for power, because finance in general is recognized as essential for organizations and business success. In a nutshell, there are good reasons for focusing financial intelligence in future studies and in practice.

This study intended to analyze to what point the use of different power bases of hierarchical superiors predict the levels of engagement at work and the resilience of workers, contributing to increase the knowledge about the behavior of municipal civil servants as to the levels of engagement at work and resilience presented. Started from the definition of power from French e Raven (1959): power is the potential influence that the agent O could cause on subject P; it was adopted the concept of engagement at work from Schaufeli and Bakker (2003), that define engagement at work as a positive motivational construct, characterized by vigor, dedication and absorption, always related to work, what implies a feeling of accomplishment, involves positive cognitive state, is persistent in time, presenting, that way, motivational and social nature, and at last, used the concept of Grotberg (2005) that defined resilience as the human capacity to face, overcome, and even be strengthened by experiences of adversity . For that, it was defined as the general goal to test the predictive capacity of the social power bases of bosses over the resilience and the engagement at work in municipal civil servants of Diadema SP. Participated on this study 95 municipal civil servants of the Diadema City, SP, with a small majority of feminine individuals (51,6%), with larger percentage of age between 25 and 40 years old (38,9%). The majority of participants (60%) declared to have a completed superior education (39,9%) or post-graduation (24,2%). The instruments used were: Bases Scale of Power of Supervisors (EBPS Escala de Bases de Poder do Supervisor), scale developed by Martins and Guimarães (2007); Resilience Evaluation Scale (EAR Escala de Avaliação da Relisiência), scale formed by Martins, Siqueira and Emilio (2011) and the UTRECHT Work Engagement Scale (UWES) that had their indicators of validity and dependability refined on this study. As a result it was partially verified the existence of association between engagement at work and resilience, because engagement at work correlated to three of the five factor of resilience: positive adaptation to changes, personal competence and persistence upfront difficulty. It was verified that the dimensions that compose the variable resilience obtained averages around the forth point of the resilience scale (frequently is true), indicating that the participants frequently notice themselves as capable of facing the adversities of life due to the high perception of persistence, capable of adapting to changes, with a good level of personal competence and spirituality. Verified that the averages on the dimensions that compose the variable of engagement at work were too close of the forth point of the engagement scale (a few times a week), indicating that the notice on themselves a high level of engagement at work, meaning they have vigor, are dedicated and let themselves get absorbed by work. Verified yet that the workers realize the Power of expertise as the most applied by their hierarchical superiors with an average of 4,46 (SD = 0,71). At last, the results conquered pointed that the part and the positioning of the command didn t provoke significant impact in none of the consequent variable, ergo, power bases don t explain resilience for the participant workers of this research as also don t predict engagement at work.
Este estudo teve a intenção de analisar até que ponto o uso de diferentes bases de poder dos superiores hierárquicos predizem os níveis de engajamento no trabalho e de resiliência dos trabalhadores, colaborando para aumentar o conhecimento sobre o comportamento dos servidores públicos municipais, quanto aos níveis de engajamento no trabalho e resiliência apresentados. Partiu-se da definição de poder de French e Raven (1959): poder é a influência potencial que o agente O poderia causar no sujeito P; adotou-se o conceito de engajamento no trabalho de Schaufeli e Bakker (2003), que definem engajamento no trabalho como um construto motivacional positivo, caracterizado por vigor, dedicação e absorção, sempre relacionado ao trabalho, o qual implica sentimento de realização, envolve estado cognitivo positivo, é persistente no tempo, apresentando, assim, natureza motivacional e social e por fim utilizou-se o conceito de Grotberg (2005) que define resiliência como a capacidade humana para enfrentar, vencer e ser fortalecido ou transformado por experiências de adversidades . Para isto, definiu-se como objetivo geral testar a capacidade preditiva das bases de poder social dos chefes sobre a resiliência e o engajamento no trabalho, em servidores públicos municipais de Diadema - SP. Participaram deste estudo 95 servidores públicos municipais do município de Diadema, SP, com pequena maioria de indivíduos do sexo feminino (51,6%), com maior percentual de idade entre 25 e 40 anos (38,9%). A maioria dos participantes (60%) declarou possuir nível superior completo (35,8%) ou pós-graduação (24,2%). Utilizou-se os instrumentos: Escala de Bases de Poder do Supervisor (EBPS), escala desenvolvida por Martins e Guimarães (2007); Escala de Avaliação da Resiliência (EAR), escala construída por Martins, Siqueira e Emilio (2011) e a Escala de Engajamento no Trabalho de UTRECHT (UWES) que tiveram seus indicadores de validade e fidedignidade apurados neste estudo. Como resultado constatou-se parcialmente a existência de associação entre engajamento no trabalho e resiliência, pois engajamento no trabalho correlacionou-se com três dos cinco fatores de resiliência: adaptação positiva à mudanças, competência pessoal e persistência diante de dificuldade. Verificou-se que as dimensões que compõem a variável resiliência obtiveram médias ao redor do ponto quatro da escala de resiliência (frequentemente é verdade), indicando que os participantes frequentemente percebem a si mesmos como capazes de enfrentar as adversidades da vida em função da sua alta percepção de persistência, capazes de adaptar-se às mudanças, com bom nível de competência pessoal e de espiritualidade. Constatou-se que as médias nas dimensões que compõem a variável engajamento no trabalho ficaram muito próximas do ponto quatro da escala de engajamento (algumas vezes na semana), indicando que eles percebem em si um alto grau engajamento no trabalho, ou seja, que possuem vigor, são dedicados e deixam-se absorver pelo trabalho. Verificou-se ainda que os trabalhadores percebem o poder de perícia como o mais empregado pelos seus superiores hierárquicos com média de 4,46 (DP= 0,71). Por fim, os resultados obtidos apontaram que o papel e o posicionamento da chefia não provocaram impacto significativo em nenhuma das variáveis consequentes, portanto, bases de poder não explicam resiliência para os trabalhadores participantes desta pesquisa como também não predisseram engajamento no trabalho.

Abstract:

The social power typology originally identified by French and Raven (1959) and later modified by Raven (1965, 1992) was used to examine factors related to school psychological consultation. Specifically, this dissertation investigated whether the gender and amount of relevant professional experience of psychologists (i.e., consultants) and teachers (i.e., consultees) influenced how likely psychologists were to use soft power bases when consulting with teachers. In addition, this study examined whether consultants? use of soft power bases was related to their self-evaluations of effectiveness during consultation. Two instruments were employed: the Interpersonal Power Inventory (IPI), which was modified to examine school consultants? likelihood of use of social power bases when consulting with teachers; and the Consultant Evaluation Form (CEF), which was modified to assess psychologists? self-evaluations of effectiveness during teacher consultation. The IPI and CEF were mailed together to 1,000 Nationally Certified School Psychologists, and a total of 352 usable protocols were returned. Results indicated that when consulting with female teachers, female consultants were not more likely to use positive referent power than the other four soft power bases combined; however, male psychologists were more likely to use positive expert power than the other four soft power bases combined. Additional results indicated that consultants? likelihood of use of soft power bases was not related to their years of professional experience, although results of a secondary set of analyses using a slightly different constellation of soft power bases did yield a significant relationship between the two variables. Findings also revealed a significant relationship between consultees? years of experience and consultants? use of soft power bases, in that school consultants were less likely to use soft power with more experienced teachers. Finally, results indicated a significant, positive relationship between consultants? likelihood of use of soft power bases and their self-evaluations of effectiveness during consultation. Findings of this study suggest that the experience level of teachers plays a significant role in determining the influence strategies used by psychologists during consultation. Results also imply that consultants? use of soft power is related to perceptions of more effective school consultation.

This study sought to identify the feasibility of utilizing a radioisotope thermal (thermoelectric/stirling) generator to provide power to a deployed USMC Expeditionary Force. The conceptual system architecture was constructed through use of the systems engineering process, identifying necessary subsystems and integration boundaries. Radioisotope comparison was then performed, utilizing weighted design factors. It was determined that Sr-90, Cs-137, and Cm-244 would be the most effective fuel sources for this mission area. By analyzing current thermoelectric technology, it was determined that maximum system efficiency is limited to 1015 percent when utilizing available lead telluride thermoelectrics. Barriers to development of identified physical subsystem components were then identified, including health and environmental hazards of potential isotopes, as well as shielding criteria. The system development was found to be feasible and additional design work and development work is proposed.

Abstract:

Ser eficiente é um requisito para a sustentabilidade das empresas concessionárias de distribuição de energia elétrica no Brasil. A busca pela eficiência deve estar em harmonia com a melhoria contínua da qualidade, da segurança e da satisfação dos consumidores e das partes envolvidas. O desafio de atender múltiplos objetivos requer que as empresas do setor desenvolvam soluções inovadoras, com a mudança de processos, tecnologia, estrutura e a capacitação das pessoas. Desenvolver um modelo operacional eficiente e uma gestão rigorosa dos custos são fatores-chave para o sucesso das empresas, considerando o contexto regulatório de revisão tarifária que incentiva a melhoria do desempenho. O modelo operacional é definido a partir da organização logística dos recursos para atendimento da demanda de serviços, que define também os custos fixos e variáveis de pessoal (salário, horas extras, refeições), infraestrutura (manutenção de prédios, ferramentas e equipamentos) e deslocamentos (manutenção de veículos, combustível), por exemplo. A melhor alocação e o melhor dimensionamento de bases operacionais possibilitam a redução dos custos com deslocamento e infraestrutura, favorecendo o aproveitamento da força de trabalho em campo, a melhoria do atendimento dos clientes e da segurança dos colaboradores. Este trabalho apresenta uma metodologia de otimização de custos através da alocação de bases e equipes operacionais, com o modelamento matemático dos objetivos e restrições do negócio e a aplicação de algoritmo evolutivo para busca das melhores soluções, sendo uma aplicação de Pesquisa Operacional, no campo da Localização de Instalações, em distribuição de energia elétrica. O modelo de otimização desenvolvido possibilita a busca pelo ponto de equilíbrio ótimo que minimiza o custo total formado pelos custos de infraestrutura, frota (veículos e deslocamentos) e pessoal. O algoritmo evolutivo aplicado no modelo oferece soluções otimizadas pelo melhoramento de conjuntos de variáveis binárias com base em conceitos da evolução genética. O modelo de otimização fornece o detalhamento de toda a estrutura operacional e de custos para uma determinada solução do problema, utilizando premissas de produtividade e deslocamentos (velocidades e distâncias) para definir as abrangências de atuação das bases operacionais, recursos (equipes, pessoas, veículos) necessários para atendimento da demanda de serviços, e projetar todos os custos fixos e variáveis associados. A metodologia desenvolvida neste trabalho considera também a projeção de demanda futura para a aplicação no estudo de caso, que evidenciou a efetividade da metodologia como ferramenta para a melhoria da eficiência operacional em empresas de distribuição de energia elétrica.
Being efficient is a requirement for the sustainability of electricity distribution companies in Brazil. The quest for efficiency must be in harmony with the continuous improvement of quality, safety and satisfaction of customers and all stakeholders involved. The challenge of attending multi-objectives requires companies in the sector to develop innovative solutions with the change of processes, technology, structure and enabling their professionals to drive this. Developing an efficient operational model and a strict cost management are keys for companies to achieve success, considering the regulatory context of tariff reviewing that encourages performance improvement. The operational model is defined from the logistics organization of resources to meet the demand of services, which also defines fixed and variable costs with people/teams (payments, overtime, meals), infrastructure (maintenance of building, tools and equipments) and fleet (maintenance of vehicles and fuel costs), for example. The best allocation and the best design of operational facilities (or operational bases) will reduce infrastructure costs and truck rolls, releasing workforce to attend customers and reducing displacements risks. This work presents a cost optimization methodology through the allocation of operational bases and teams, with the mathematical modelling of business objectives, constraints and using Evolutionary Algorithm to find the best solution, as an application of Operations Research in the field of Facility Location in electricity distribution. The optimization model enables the search for the optimal balance point that minimizes the total cost formed by infrastructure, fleet and people. The Evolutionary Algorithm applied in the model offers optimized solutions through the improvement of sets of binary variables based on genetic evolution concepts. The optimization model also gives detailed information about the operational structure and costs for a given allocation solution, using productivity and displacements (speed, distances) information to define the service regions for each operational base and resources (people, vehicles) needed to attend the demand of services, defining all fixed and variable costs for this. The methodology presented in this paper also considers the future demand of services (forecast), used in a case study that showed the effectives of this methodology as a tool for the improvement of operational efficiency in electricity distribution companies.

Esse estudo materializa a tese de doutoramento em que se discute, que as bases de sustentação política de Getúlio Vargas, no período que vai de 1930 a 1934, estavam assentadas no Nordeste. Para esse espaço regional foram direcionadas as ações, que promoveram a estruturação política do Estado que emergiu com a revolução de 1930. No Nordeste, a ação política do Governo Provisório agenciou o alinhamento político e de poder de Getúlio Vargas pelo discurso factual de poder, cujo fim foi justificar a realização da revolução de 1930 e identifica-la como necessária ao reordenamento político do Brasil. Com o objetivo de desterritorializar a influência política e de poder do entorno paulista, Getúlio Vargas empreendeu uma serie de ajustes que fizeram emergir uma nova territorialidade de poder a partir do Nordeste. Sustentado pelos militares, a consolidação das interventorias neste espaço regional, contribuiu para que as demandas econômicas e os ajustamentos de poder no Nordeste garantisse ao Governo Provisório o apoio em bloco, frente aos interesses de poder do entorno paulista.

Abstract:

In recent years special education administrators have frequently found themselves in conflict with parents of handicapped children regarding such issues as: (1) private school placement of handicapped children; (2) transportation of handicapped children; (3) the provision of related services for handicapped children; and (4) due process hearings requested regarding the evaluation and placement of handicapped children. The problem this study investigated is whether the power base used by the special education administrator to influence conflicts with parents is affected by the socioeconomic status of the parents, the race of the child and the parents, and/or the handicapping condition of the child. In order to examine how special education administrators use social power to influence conflicts with parents seven bases of social power were studied. The original five power bases developed by French and Raven (1959)--expert, referent, legitimate, reward, and coerci ve--were used, plus two additional bases--information power developed by Raven and Kruglanski (1970) and connection power developed by Hersey, Blanchard and Natemeyer (1979). In addition three variables (the socio-economic status of the parents, the race of the parents and the child, and the handicapping condition of the child) were examined through the use of scenario questions. The scenario questions were developed by the researcher and were tested to establish their reliability and validity. The study examined five primary research questions, secondary research questions, and a research hypothesis. While no definite pattern of responses emerged, it was found that (1) administrator's decision making appeared to be sensitive to the context in which it was made; (2) administrators relied on reward power to influence conflicts; and (3) administrators used information power to resolve conflicts with white, high SES parents.

Abstract:

This thesis aims to explain how British naval power was sustained in the Indian Ocean during the French Revolutionary and Napoleonic Wars. To improve efficiency and economy, the Admiralty had to reorganise the management of shore support services, as well as to rationalise the bases available to the navy to meet the enemy it faced. The basic proposal of this thesis is that British naval power was projected overseas by the Admiralty's effective reconciliation of two competing demands, the naval demand for strategic deployment and the domestic demand for reform. The thesis argues that British naval power in the Indian Ocean was increased by the acquisition of the Cape of Good Hope and Trincomalee and the naval bases built at these locations. The removal of the navy from complete dependence on the East India Company for support services was part of a long term policy of increasing Admiralty control of facilities in the east. In 1793 Bombay was the main naval base but Madras quickly became another hub supporting naval activities in the east. Other locations were considered. Calcutta was used and investigations were made into developing Penang as a navy base before Trincomalee became part of Britain’s long-term naval infrastructure. At the Cape a separate naval command was given responsibility for part of the Indian Ocean. Following the capture of Mauritius in 1810 this island was used temporarily as a forward support base. Admiralty control of the naval support services delivered to the squadrons at the Cape and in the East Indies was dramatically improved by the appointment overseas of resident commissioners from 1809. This resulted from the implementation of the recommendations of the Commission of Naval Revision, first suggested by the Commissioners on Fees in 1788. Resident commissioners ensured Admiralty instructions and policies were implemented and executed, resulting in improved efficiency and reduced costs.

Studiens hypoteser har formulerats med grund i resursberoendeteorin, upper echelon-teorin, teorin om tokens samt tidigare forskning. Hypoteserna syftar till att testa studiens inflytandeindex. Slutsats: Studien finner att det konstruerade indexet kan fånga individers och gruppers inflytande i en styrelse på ett mer teoretiskt grundat sätt gentemot de traditionella måtten andel och kritisk massa. Det framkom genom indexet att styrelseledamöternas inflytande inte har någon betydelse för bolagsprestationer.
Background: Previous studies have conducted its research on the premise that a membership on the board means that you have a certain impact on the results of the company. Further on, it remains a dilemma whether it’s possible to determine if a member of the board has this impact regardless of which person it is and which role they have on the board. Purpose: The study aims to explain the influence of board members and board groups on company performance through the development of an index of influence. Method: The method used is a cross-sectional study with a deductive approach. The hypothesis of the study has been formulated based on resource dependence theory, the upper echelon-theory, the theory of tokens and previous studies. The purpose of the hypothesis is to test the index of influence of the study. Conclusion: The study finds that the constructed index can capture the influence of individuals and groups on a board in a more theoretically grounded way compared to the traditional measures of proportion and critical mass. It emerged from the index that the board members' influence has no significance for company performance.

Abstract:

Muitos grupos de pesquisa já trabalharam com o desenvolvimento de conjuntos de bases, no intuito de obter melhores resultados em tempo e custo de cálculo computacional reduzidos. Para tal finalidade, o tamanho e a precisão são fatores a ser considerados, para que o número de funções do conjunto gerado proporcione uma boa descrição do sistema em estudo, num tempo de convergência reduzido. Esta dissertação tem como objetivo apresentar os conjuntos de bases obtidos pelo Método da Coordenada Geradora, para os átomos Na, Mg, Al, Si, P, S e Cl, e avaliar a qualidade de tais conjuntos pela comparação da energia eletrônica total, em nível atômico e molecular. Foi realizada uma busca para a obtenção do melhor conjunto contraído e do melhor conjunto de funções de polarização. A qualidade do conjunto gerado foi avaliada pelo cálculo DFT-B3LYP, cujos resultados foram comparados aos valores obtidos por cálculos que utilizam funções de bases conhecidas na literatura, tais como: cc-pVXZ do Dunning e pc-n do Jensen. Pelos resultados obtidos, pode-se notar que os conjuntos de bases gerados neste trabalho, denominados MCG-3d2f, podem representar sistemas atômicos ou moleculares. Tanto os valores de energia quanto os de tempo computacional são equivalentes e, em alguns casos, melhores que os obtidos aqui com os conjuntos de bases escolhidos como referência (conjuntos de Dunning e Jensen).
Many research groups have been working with the development of basis sets in order to get the best results in reduced time and cost of computational calculation. It is known that for such purpose, size and accuracy are the primary factors to be considered, so that the number of the generated set of functions allows a good description of the system being studied in a small convergence time. This essay aims to present the basis sets obtained by the Generator Coordinate Method for the atoms Na, Mg, Al, Si, P, S and Cl, as well as evaluating the quality of such clusters by comparing the electron energy at atomic and molecular levels. A research was also performed to obtain the best set contracted as well as the best set of polarization functions. The quality of the generated set was evaluated by calculating DFT-B3LYP results, which were compared to values obtained through calculation using basis functions such as cc-pVXZ of Dunning and pcn of Jensen. It can be noted, from the results obtained, that the basis sets generated in this study, named MCG-3d2f, may well represent atomic or molecular systems. Energy values and the computational time are equivalent and in some cases, even better than those obtained with the sets of bases chosen here as reference sets (Dunning and Jensen).

Abstract:

This thesis presents work around 3 themes: dark energy, gravitational waves and Bayesian inference. Both dark energy and gravitational wave physics are not yet well constrained. They present interesting challenges for Bayesian inference, which attempts to quantify our knowledge of the universe given our astrophysical data. A dark energy equation of state reconstruction analysis finds that the data favours the vacuum dark energy equation of state $w {=} -1$ model. Deviations from vacuum dark energy are shown to favour the super-negative ‘phantom’ dark energy regime of $w {< } -1$, but at low statistical significance. The constraining power of various datasets is quantified, finding that data constraints peak around redshift $z = 0.2$ due to baryonic acoustic oscillation and supernovae data constraints, whilst cosmic microwave background radiation and Lyman-$\alpha$ forest constraints are less significant. Specific models with a conformal time symmetry in the Friedmann equation and with an additional dark energy component are tested and shown to be competitive to the vacuum dark energy model by Bayesian model selection analysis: that they are not ruled out is believed to be largely due to poor data quality for deciding between existing models. Recent detections of gravitational waves by the LIGO collaboration enable the first gravitational wave tests of general relativity. An existing test in the literature is used and sped up significantly by a novel method developed in this thesis. The test computes posterior odds ratios, and the new method is shown to compute these accurately and efficiently. Compared to computing evidences, the method presented provides an approximate 100 times reduction in the number of likelihood calculations required to compute evidences at a given accuracy. Further testing may identify a significant advance in Bayesian model selection using nested sampling, as the method is completely general and straightforward to implement. We note that efficiency gains are not guaranteed and may be problem specific: further research is needed.

Abstract:

Dissertação de mestrado em Comportamento Organizacional
As organizações confrontam-se com envolventes cada vez mais competitivas e turbulentas. Neste cenário, os modos do saber fazer e os conhecimentos empíricos cruzam-se no dia a dia, sempre na procura da rentabilização e das melhores práticas de gestão. Procurámos neste estudo contribuir para esta sustentação, recorrendo a várias dimensões (poder, confiança e compromisso), as quais são operacionalizadas na organização através da função e centradas nas competências dos indivíduos que as executam. Pretende-se, pois, verificar se para funções diferentes, devem ser aplicadas práticas de gestão de recursos humanos diferentes. Com base no conceito de função que se pode traduzir na especificação formal ou informal das actividades executadas pelos trabalhadores, incluindo tanto aspectos de estrutura como interpessoais; considerando necessidades e exigências da organização e dos indivíduos, utilizámos o modelo das "características do desempenho da função" descrito por Ríos e Sánchez (1997), com o intuito de formalizar a pesquisa, a qual tem por base as diferenças individuais e a adequação à realidade do sector em estudo. Se por um lado, através da função, identificámos o meio de alcançar o objectivo a que nos propomos, por outro é necessário disponibilizar as ferramentas fundamentais, como sejam o poder, o compromisso e a confiança para conduzir os indivíduos ao caminho certo. Sendo o sector em estudo, sector automóvel, caracterizado pelo trabalho em equipa, foi necessário adequar estas dimensões tão importantes ao alcance do desempenho. Na abordagem à variável poder as relações entre as chefias e os subordinados, a confiança na chefia e o equilíbrio entre os princípios da equipa e a chefia revelam-se fundamentais para os resultados da organização. A par deste, o compromisso da equipa é um factor decisivo para a estabilidade e cooperação no seio organização. Tendo como base uma amostra de 162 indivíduos, procurámos neste estudo analisar o problema acima mencionado em quatro organizações do sector automóvel, o qual se caracteriza por uma diversidade de funções (comercial, administrativos, chefias e pós-venda) sendo o trabalho em equipa a chave para o seu sucesso. Cabe, pois, a cada uma reunir os instrumentos de gestão adequados, de forma a aplicá-los no melhor sentido da sua rentabilização. Foram utilizados três instrumentos a fim de medir a percepção dos colaboradores em relação a cada uma das variáveis. O questionário do poder foi utilizado com base no modelo de French e Raven, tendo sido validado por Munduate e Dorado (1993). A confiança na chefia foi avaliada através de um questionário apresentado por Dirks (2000). A variável compromisso da equipa foi medida através do questionário de forma completa (15 itens) de Organizational Commitment Questionaire (Porter, Steers, Mowday & Boulian, 1974). O tratamento dos dados foi elaborado em três momentos. No primeiro procedeu-se ao estudo da fidelidade; em continuidade foi testada a significância das diferenças entre as várias áreas funcionais e as variáveis dependentes, tendo-se recorrido à análise de variância multivariada - Manova. Finalizando o tratamento estatístico utilizou-se o coeficiente de correlação de Pearson a fim de verificar quais as relações entre as variáveis de interesse e como se comportam. Como resultado da análise, verificaram-se diferenças significativas entre as variáveis em estudo, a saber: - Na variável poder coercivo, as funções que apresentam diferenças são a função comercial e chefia. Na variável poder de experiência, a função que percepciona diferenças é a função do pós-venda. - Na variável confiança na chefia, as funções nas quais foram encontradas diferenças foram os comerciais e pós-venda. - No compromisso da equipa, as funções nas quais foram encontradas diferenças foram os comerciais e chefias. Desta análise, resultou que, nas variáveis estudadas a função administrativa não apresentou diferenças significativas em relação aos restantes grupos funcionais. Daqui resulta que é necessário preparar os gestores e as equipas de forma a adoptar as estratégias adequadas e necessárias a cada uma das funções, caso a caso e não de forma indiferenciada. Assim, podemos concluir que neste sector e utilizando as variáveis de intervenção - poder, compromisso da equipa e a confiança na chefia, devem-se utilizar práticas diferenciadas de gestão de recursos humanos com vista a encontrar soluções de eficácia na organização.

Abstract:

This study examines the power bases of school district chief executive officers using a modified version of a conceptual framework of power proposed by French and Raven (1959). Their bases or sources of power are coercive, reward, legitimate, expert and referent. These five bases are extended to include information power and connection power. Significant differences exist among the three self-perceived power profiles, and among the perception-of-other power profiles for five of the independent variables. In the self-perceived power profiles, superintendents perceive themselves to use significantly more coercive power in their working relationships with school principals. In the perception-of-other power profiles, significant differences are found when data are classified according to (i) superintendents' years of experience in their current positions, (ii) age of subordinate personnel, (iii) age of superintendents, (iv) size of school districts, and (v) career-bound and place-bound superintendents who have 10 years or less experience. No significant differences exist for the independent variables (i) type of subordinate personnel, (ii) experience of subordinate personnel, (iii) gender of subordinate personnel, (iv) distance from central office, and (v) type of school district (Catholic or Integrated). No significant differences exist among the three self/other power profiles that compare the superintendent's self-perception with the perceptions of the three subordinate groups. The more experienced superintendents receive a significantly lower rating for legitimate power. The youngest superintendents receive a significantly lower rating for the information power, the older superintendents receive a significantly lower rating for the legitimate power, and the medium age superintendents in comparison to the younger receive a significantly lower rating for expert power. The oldest subordinates perceive superintendents to have significantly more legitimate power but significantly less referent power. Superintendents in the larger districts are perceived to use significantly less connection power and significantly more legitimate power. When district size is based on the number of schools, superintendents in the larger districts use significantly less connection power and significantly more expert power. For the perceived power bases of career-bound and place-bound superintendents with 10 years or less experience, the career-bound superintendents use significantly more coercive power. Expert and legitimate power bases always receive ratings that are higher than any of the other five power bases; the three intermediate bases are information, referent and reward power; and coercive and connection power always receive the lowest ratings.

Abstract:

Les bases aériennes sont des éléments incontournables de la puissance aérienne car sans infrastructures dédiées, l’aviation militaire est inopérante. La répartition géographique des bases aériennes répond à des stratégies politiques, militaires mais également économiques. Elles en sont les traductions spatiales. De fait, organisées en réseaux, les bases aériennes concourent à définir la géostratégie aérienne. L’analyse spatiale et historique du réseau des bases aériennes françaises depuis le début du XXe siècle démontre la place prégnante de ce maillage dans la stratégie française et constitue le reflet de la perception de la France de son espace environnant. D’abord, le réseau illustre, dans la stratégie territoriale française, la prééminence d’une posture défensive du sanctuaire métropolitain, à l’origine d’une « France différenciée » dont le découpage territorial s’effectue selon la répartition des types de bases aériennes. Ensuite, le réseau des bases aériennes extra-métropolitaines, à la différence de sa consœur métropolitaine, n’est pas seulement régi par une stratégie de défense. Dans un premier temps, dans le cadre de sa politique coloniale, la France utilise son réseau comme instrument d’exploration, de contrôle et conservation de territoires ; puis, dans le cadre de sa politique étrangère, elle s’en sert comme d’un moyen de préservation de ses intérêts vitaux dans les pays étrangers et les territoires français d’outre-mer
Air bases are inescapable elements of air power because without dedicated infrastructures, military aviation is ineffective. The geographical distribution of air bases answers political, military but also economic strategies. Air bases are the spatial translation of these strategies. In fact, air bases organized in networks contribute to define the air geostrategy. The spatial and historical analysis of the French air bases network since the beginning of the XXth century demonstrates the prominence of this web in the French strategy and reflects the French perception of its surrounding space. First the network illustrates the superiority of a defensive posture of the metropolitan sanctuary in the French territorial strategy, at the origin of a “differentiated France” sub-divided according to the distribution of various air base types. Then, the overseas air bases network, unlike its metropolitan counterpart, is not governed solely by a defense strategy. Within the colonial policy framework, France uses its network as instrument of exploration, control and preservation of territories. In addition, within the foreign policy framework, France uses it as of a means of conservation of its vital interests in foreign countries and French overseas territories

O objetivo central desse trabalho Ã reconstruir a trajetÃria polÃtica de quatro deputados estaduais que possuem a regiÃo dos Inhamuns como principal circunscriÃÃo eleitoral informal e o municÃpio de TauÃ como principal colÃgio eleitoral. Foi analisada a trajetÃria polÃtica de JÃlio GonÃalves RÃgo e Antonio Gomes da Silva CÃmara no perÃodo em que eles foram hegemÃnicos, de 1975 a 1994, e de Domingos Gomes de Aguiar Filho e Idemar Loiola CitÃ no perÃodo de 1995 a 2010. A pesquisa teve por finalidade compreender como esses deputados sÃo recrutados, como conquistam e mantÃm o poder local em TauÃ, como se relacionam com sua base eleitoral, como estabelecem relaÃÃes com deputados federais, governadores, prefeitos e vereadores, quais suas estratÃgias de conquista de votos e quem sÃo seus cabos eleitorais nos municÃpios. O recorte temporal da pesquisa Ã de quatro dÃcadas. Para a realizaÃÃo desse estudo foram realizadas entrevistas formais e informais com atores polÃticos qualificados, pesquisas em jornais locais e em ÃrgÃos como IBGE, TRE-CE e IPECE, alÃm de pesquisas bibliogrÃficas.
The main goal of this paper is to reconstruct the political trajectory of four state representatives who have the region of the Inhamuns as main informal electoral circumscription and the city of TauÃ as main electoral college. We analyzed the political career of Julio RÃgo GonÃalves and Antonio Gomes da Silva CÃmara in the period in which they were hegemonic, from 1975 to 1994, and Domingos Gomes de Aguiar Filho and Idemar Loyola CitÃ, from 1995 to 2010. The research was aimed at understanding how these members are recruited, how they win and keep local power in TauÃ, how they relate to their electoral base and establish relations with congressmen, governors, mayors and councilors, what are their strategies for winning votes and who are their canvassers in the cities. The time frame of this research is four decades. To achieve this study, formal and informal interviews were conducted with qualified political actors as well as researches in local newspapers, institutions such as IBGE, TRE-CE and IPECE, and also literature searches.

Abstract:

La tesis propone el concepto de poder creador como un concepto que nos permite abordar la propuesta emancipatoria de Marx. Para ello, la tesis ha realizado el rastreo de las bases antropológicas y ontológicas en la obra temprana y tardía de Marx que puedan permitir elaborar dicho concepto. La hipótesis principal postula que el concepto que Marx desarrolla como “trabajo vivo” es un concepto bisagra entre su concepción ontológica y antropológica, por un lado, y sus reflexiones sobre los intereses emancipatorios, por otro lado. En ese sentido, el poder creador aparece como el potencial inherente que caracteriza al trabajo vivo. Potencial que el capital extrae del trabajo vivo para enajenarlo y direccionarlo constantemente hacia sus fines, pero que, a pesar de la determinación que el capital le impone al trabajo vivo para desarrollarse, no anula en este la posibilidad de una reapropiación de su propia potencialidad. La presente tesis se plantea como pregunta principal: ¿cuáles son las formas en que la ontología comprendida en el poder creador se articula con las circunstancias objetivas del modo de producción capitalista para desarrollar una disposición hacia su emancipación frente a aquellas mismas circunstancias? La tesis plantea como conclusión que las circunstancias objetivas del modo de producción capitalista son una realidad mistificada por el capital; realidad que, sin embargo, no es capaz de suprimir la prioridad ontológica del trabajo vivo como “existencia no-objetivada”. La alteridad del trabajo vivo permanece irreductible frente al capital y por ello su enajenación es solo una forma histórica de su actividad, una forma susceptible de ser superada.

Resumo: Este trabalho apresenta ferramentas e procedimentos para a consolidação de dados de usinas hidrelétricas brasileiras. O objetivo é melhorar a qualidade dos dados que servem como entrada aos modelos computacionais utilizados no planejamento e na programação da operação energética. Como ferramentas de suporte à aplicação da metodologia, são descritos: o gerenciador de dados HydroData, o construtor de consultas HydroConsulta e o simulador da operação de usinas hidrelétricas HydroSim. A seqüência de procedimentos está dividida em duas etapas: análise da coerência da base de dados e consolidação efetiva das funções. No estudo de caso a metodologia foi aplicada a uma usina hidrelétrica que faz parte do Sistema Interligado Nacional e cuja operação está sob a coordenação e controle do Operador Nacional do Sistema Elétrico. A fim de avaliar os procedimentos, foram feitos estudos de reprodução da operação hidrelétrica, para o curtíssimo e curto prazo, alternando dados oficiais e dados consolidados de acordo com a técnica apresentada. Os resultados mostram que a melhoria da qualidade dos dados, obtida com a aplicação da metodologia proposta, aproxima a operação simulada da operação real. Dessa forma, ela contribui para a eficiência, confiabilidade e análise de desempenho dos modelos computacionais em uso no setor elétrico brasileiro.
Abstract: This work presents tools and procedures for the data consolidation from Brazilian hydroelectric plants. The objective is to improve the quality of the input data to the computational models used in the mid and short term operation planning. As support tool to the application of the methodology, are described: the data manager HydroData, the queries builder HydroConsulta and the simulator of the hydroelectric plants operation HydroSim. The procedures sequence is divided into two steps: analysis of the database coherency and effective consolidation of the functions. In the case study the methodology was applied to a hydroelectric plant which is part of the National Interconnected System and whose operation is under the coordination and control of the Independent System Operator. In order to evaluate the procedures, were made studies of hydroelectric operation reproduction, to the mid and short term, alternating official data and consolidated data in accordance with the technique presented. The results show that the improvement of the data quality, obtained with the application of the proposed methodology, brings the simulated and real operation closer. This way, it contributes to the efficiency, reliability and performance analysis of the computational models in use in the Brazilian electric sector.

O presente trabalho traz como objetivo identificar, analisar e propor alternativa para a coibição da poluição sonora causada pela aglomeração de pessoas no entorno de bares, restaurantes e similares. Esta se caracteriza pela perturbação do sossego público por meio de ruídos ou barulhos provenientes de inúmeras fontes urbanas. A poluição sonora pode decorrer do exercício de atividades econômicas ou mesmo da prática do lazer. Algumas fontes poluidoras como as provocadas pela circulação de veículos, construção civil, templos religiosos, casas noturnas, bares e lanchonetes com música ao vivo ou mecânica, apitos, sirenes, entre outros, já se encontram devidamente regulamentadas por leis, resoluções ou atos normativos em geral, no Município de Santos. A dificuldade encontra-se na caracterização da responsabilidade pela poluição sonora provocada pela aglomeração de pessoas no entorno de bares, lanchonete, restaurantes e similares, atualmente a fonte poluidora urbana mais presente na rotina das cidades.

Uma vez que o desempenho geral das organizações parece estar atrelado à sua capacidade de flexibilidade e mudança, ao desempenho do seu capital humano e ao desenvolvimento de práticas e competências integradas, coerentes e facilitadoras da estratégia organizacional, o setor público, após passar por um modelo de Estado patrimonialista e burocrático, tem buscado disseminar o modelo gerencialista, promovendo, por meio de decretos e atos normativos, reformas e ações que possibilitem a melhora da qualidade e eficiência neste setor. Tomados aqui como proposta de mudança organizacional, estes decretos e atos normativos contam com a influência dos gestores para sua consecução e aplicação eficaz. Percebendo o poder e sua dinâmica como inerentes aos atos de influência social que ocorrem nos processos organizacionais, fez-se neste trabalho um estudo também sobre este tema. Assim, inicialmente se aborda os Modelos de Gestão no Brasil (patrimonialista, burocrático e gerencial) e a Gestão Estratégica de Pessoas no setor público, em seguida trata-se de Mudança Organizacional e suas tipologias, e por fim, de Poder nas Organizações. Metodologicamente este trabalho está estruturado em um estudo principal, que foi realizado por meio de levantamento de opiniões. Foram aplicados dois instrumentos de pesquisa, o primeiro identificou as bases de poder utilizadas pelos gestores e o segundo identificou o tipo de mudança organizacional percebida pelos funcionários. Assim, a partir de regressões múltiplas padrão, foi possível atingir o objetivo geral a que o trabalho se propõe, qual seja analisar a influência das bases de poder usadas pelos gestores de linha de recursos humanos na percepção de funcionários de organizações públicas a respeito da mudança - transformacional ou transacional – supostamente decorrente da publicação da Política Nacional de Desenvolvimento de Pessoal. A partir dos resultados, foi possível perceber que essa influência é ínfima. Desta forma, por fim discutem-se as possíveis causa desta constatação. ______________________________________________________________________________ ABSTRACT
Since the overall performance of organizations seems to be tied to its ability to change and flexibility, the performance of its human capital and the development of practical skills and integrated, coherent and facilitators of organizational strategy, the public sector, after passing through a model State patrimonial and bureaucratic, has sought to spread the managerialist model, promoting, through decrees and normative acts, reforms and actions that facilitate the improvement of quality and efficiency in this sector. Taken here as a proposed organizational change, these decrees and normative acts have the influence of managers for their achievement and effective implementation. Realizing the power and dynamics as inherent to acts of social influence that occur in organizational processes, it is also in this paper a study on this topic. Thus, initially covers the Management Models in Brazil (patrimonial, bureaucratic and managerial) and the Strategic Management of People in the public sector, then it is Organizational Change and its typologies, and finally Power in Organizations. Methodologically this work is structured in a major study that will be conducted by surveying opinions. Be applied two survey instruments, the first will identify the bases of power used by managers and the second will identify the type of organizational change perceived by employees. Thus, you can achieve the overall goal that the work is proposed, which is to analyze the influence of the power bases used by line managers in human resource perception of public officials about the change - transformational or transactional - supposedly due the publication of the National Staff Development.

Abstract:

El trabajo muestra la evolución de la trama política general, española mediante el análisis en una zona concreta de la Región de Murcia en el período 1891-1910. La primera parte indaga en la estructura de la propiedad presentando a los grupos sociales. La segunda parte atiende expresamente a la política, mostrando la relación entre la dinámica de los poderes locales y del estado a través de la organización de las elecciones. La tesis demuestra que en el período estudiado no se produce ni una sola elección libre y democrática. Finalmente expone información sobre las revueltas sociales que se produjeron y la contundente represión en una aparente contradicción entre actitudes de paternalismo y de violencia, las dos caras definitorias del sistema caciquil.
The study is centred upon the small boroughs which formed three separately named districts, in the period 1891-1910, and which formed societies of a rural charachter, in the midst of the general transformation towards capitalistic norms. These district were characterised by the unequal distribution of property, - concentrated in few hands: - those of the descendants of the established oligarchy, and those of a reduced number of merchants and landowners, these latter two grown richer by the forming of matrimonial ties with the former. Only between a quarter and a half of the individuals who comprised these rural-societes had access to the ownership ofland. The rest was made up of tenant- farmers, casual-workers, and the poor. All undergoing a new breed of property, that property associated with work, - a 'structural-proverty'; into which this study has attempted to penetrate. The division has been found to have been underlined, due to the inexistence of associations capable of representing collective interests, - the first of such movements oniy appeared during this same periodo it was within this context that universal-suffrage for men first appeared, which, in the three districts studied was so denaturalised as not to have produced a single democratic election whose voting resulted in its electors being representad by any freely- appointed parliamentarian. This being so, it has been necessary to investigase the totality of electoral resuits and returns of the three main groups, Conservative, Liberal, and Republican. In order to be able to exert such control over the popular vote, it was essential for the grand-propietors to create social-restrictions, managed by the local, party-bosses, who embodied the oligarchic sectors of the societies and who, via paternalistic measures, administered a goverment of authoritarian, repressive, charachter whose essence was the domination of local-counciis, and channels of communication with the word outside.

mestrado em Engenharia Eletrónica e Telecomunicações
O conceito de Smart City surge da combinação do paradigma de Internet of Things (IoT) sobre contextos urbanos aliado à exploração de soluções de Tecnologias de Informação e Comunicação (TIC). O típico cenário de Smart City tem de lidar com desafios, tais como as elevadas quantidades de sensores e geradores de dados, dos quais alguns são colocados em dispositivos de grande mobilidade, visando a recolha e geração de todo o tipo de informações e levando ao aumento do número de dispositivos comunicantes. Esta dissertação foca o desenvolvimento e implementação de uma plataforma heterogénea de sonorização ambiental com o objectivo de servir de infraestrutura para aplicações no âmbito das Smart Cities. Esta pretende tirar proveito da utilização de múltiplas tecnologias de comunicação, nomeadamente tecnologias de longo e curto alcance. Para al em disto, visto que a plataforma visa ambientes urbanos, esta tira proveito de uma rede oportunista e tolerante a atrasos, Delay Tolerant Network (DTN), através de entidades m oveis que circulam pela cidade, nomeadamente bicicletas. Assim sendo, esta dissertação propõe: (1) o desenho e desenvolvimento da rede e dos seus constituintes; (2) uma extensão a um protocolo de controlo de acesso ao meio, Medium Access Control (MAC), para a tecnologia LoRa com o objectivo de o dotar compatível para ambientes de gateways múltiplas; (3) novas estratégias de encaminhamento para a rede tolerante a atrasos, tendo em consideração a topologia e as características apresentadas por esta. As avaliações realizadas permitiram concluir que o protocolo MAC para LoRa em ambientes de gateways múltiplas proposto contribui para um aumento da escalabilidade da rede, bem como para uma melhoria do seu desempenho. Relativamente às estratégias de encaminhamento propostas para a DTN, os testes realizados permitiram avaliar o impacto que cada estratégia tem sobre o comportamento da rede, nomeadamente a taxa de entrega dos pacotes de dados, a sobrecarga da rede, o número de pacotes transmitidos, entre outros. Com estes resultados foi possível perceber as in- suficiências que as funcionalidades propostas têm sobre a solução geral, e identificar as caraterísticas necessárias de uma solução escalável para a recolha de dados massivos num ambiente de IoT.
The Smart City concept is the combination of the Internet of Things (IoT) paradigm under an urban context with the exploitation of Information and Communication Technologies (ICT) solutions. The typical Smart City scenario has to deal with an extensive amount of sensors and data generators, some of them placed in high mobile devices, deployed to collect and generate all type of information which will increase the number of communicating machines. This dissertation focuses on the development and implementation of a heterogeneous environmental sensing platform to serve as an infrastructure for Smart City applications. It aims to take advantage of the use of multiple communication technologies, namely long and short range. Being within an urban environment, the platform bene ts from an opportunistic and Delay Tolerant Network (DTN) through mobile entities that travel over the city, such as bicycles. Therefore, this dissertation proposes: (1) the design and development of the network and its elements; (2) an extension to a LoRa Medium Access Control (MAC) protocol in order to endow it with capabilities to operate in multi-gateway environments; and lastly, (3) new forwarding strategies for the opportunistic network that takes into consideration the network topology. The performed evaluations showed that the proposed multi-gateway LoRa MAC protocol contributes to increase the LoRa network scalability, as well as its performance. The performed tests to the proposed DTN forwarding strategies evaluate the impact of each strategy on the network behavior, namely the delivery ratio, network overhead, number of transmitted packets, among others. As a result, it is possible to perceive which are the in- uences introduced by the proposed functionalities on the overall solution, and identify the characteristics of a scalable solution to collect massive data in an IoT environment.

Abstract:

Les processus métier font l’objet d’une standardisation. Les voies empruntées pour cette standardisation, à savoir la domination, la confrontation et l’incorporation, puisent leur origine tant dans les méthodes que sont l’Organisation Scientifique du Travail ou le reengineering que dans les outils de type progiciel de gestion. Or, il s’avère que la prescription et la standardisation des processus métier, telles qu’elles sont réalisées, posent des problèmes dans les organisations, aux niveaux stratégique, fonctionnel et opérationnel. Notre recherche s’attache à déterminer d’une part la nature d’une autre voie de standardisation et d’autre part les conditions pouvant faciliter son émergence.Convaincus que le changement ne peut plus se définir comme l’imposition d’un modèle a priori, un standard promulgué, nous nous interrogeons sur la capacité des pratiques à reconcevoir la nature du travail de standardisation, pour aboutir à un standard pratiqué. Afin de trouver des solutions aux problèmes rencontrés avec les voies actuelles de standardisation, nous proposons un modèle conceptuel qui place les pratiques au cœur d’une spirale de création de connaissances organisationnelles. Dans le cadre d’une recherche action, nous analysons les effets de la mise en place d’un outil matérialisant notre modèle conceptuel sur des terrains qui mobilisent différemment les conditions requises pour le changement, à savoir un institut bancaire public et un groupe de presse nationale. Les résultats obtenus, variant très fortement d’un terrain à l’autre, font ressortir deux enseignements majeurs qui nous éclairent sur l’avènement du standard pratiqué comme nouvelle voie de standardisation. Nous constatons tout d’abord que le standard pratiqué se nourrit du standard promulgué pour ancrer les processus métier dans toute l’organisation. Ensuite, l’émergence et le développement d’un standard pratiqué mettent en lumière des logiques particulières à l’œuvre dans l’organisation, à savoir un processus de création de sens, le soutien d’une structure de pouvoir parallèle au pouvoir officiel et un processus d’innovation organisationnelle
Business processes undergo standardization. This standardization is achieved through domination, confrontation and incorporation, means that have their origins in methods like Taylorism, reengineering or the implementation of tools such as ERP systems. Prescription and standardization of business processes, however, create problems for organizations, at the strategic, functional and operating levels. Our research attempts to uncover on one hand novel ways of standardizing processes and on the other the conditions facilitating the emergence of these new ways.Convinced that change cannot be defined any more as the imposition of an a priori model or a promulgated standard, we investigate how work practices may contribute to the creation of standards, and result in “practiced” standards. To find solutions to the problems met with current ways of standardizing, we propose a model, which places practice at the heart of a spiral of creation of organizational knowledge. Through an action research project, we analyze the effects of the implementation of this model in two different settings, namely a public banking institute and a conglomerate of national press, requiring different conditions for change.Our findings, which differ considerably from one case to the other, highlight how the “practiced” standard emerges as a novel way of standardizing. First, we notice that the “practiced” standard feeds on the promulgated standard to anchor business processes in the whole organization. Second, the emergence and the development of the “practiced” standard bring to light specific processes that operate in the organization, namely a process of sensemaking, the support of a structure of power parallel to the official one, and a process of organizational innovation

Abstract:

Ces travaux de thèse concernent l'analyse de la robustesse (stabilité et performance) de systèmes linéaires incertains de grande dimension avec une structure hiérarchique. Ces systèmes sont obtenus en interconnectant plusieurs sous-systèmes incertains à travers une topologie hiérarchique. L'analyse de la robustesse de ces systèmes est un problème à deux aspects : la robustesse et la grande dimension. La résolution efficace de ce problème en utilisant les approches usuelles est difficile, voire impossible, à cause de la complexité et de la grande taille du problème d'optimisation associé. La conséquence de cette complexité est une augmentation importante du temps de calcul nécessaire pour résoudre ce problème d'optimisation. Afin de réduire ce temps de calcul, les travaux existants ne considèrent que des classes particulières de systèmes linéaires incertains de grande dimension. De plus, la structure hiérarchique de ces systèmes n'est pas prise en compte, ce qui montre, de notre point de vue, les limitations de ces résultats. Notre objectif est d'exploiter la structure hiérarchique de ces systèmes afin de ramener la résolution du problème d'analyse de grande taille à la résolution d'un ensemble de problèmes d'analyse de faible taille, ce qui aura comme conséquence une diminution du temps de calcul. De plus, un autre avantage de cette approche est la possibilité de résoudre ces problèmes en même temps en utilisant le calcul parallèle. Afin de prendre en compte la structure hiérarchique du système incertain de grande dimension, nous modélisons ce dernier comme l'interconnexion de plusieurs sous-systèmes incertains qui sont eux-mêmes l'interconnexion d'autres sous-systèmes incertains, etc.. Cette technique récursive de modélisation est faite sur plusieurs niveaux hiérarchiques. Afin de réduire la complexité de la représentation des systèmes incertains, nous construisons une base de propriétés de dissipativité pour chaque sous-système incertain de chaque niveau hiérarchique. Cette base contient plusieurs éléments qui caractérisent des informations utiles sur le comportement de systèmes incertains. Des exemples de telles caractérisations sont : la caractérisation de la phase incertaine, la caractérisation du gain incertain, etc.. L'obtention de chaque élément est relaxée comme un problème d'optimisation convexe ou quasi-convexe sous contraintes LMI. L'analyse de la robustesse de systèmes incertains de grande dimension est ensuite faite de façon hiérarchique en propageant ces bases de propriétés de dissipativité d'un niveau hiérarchique à un autre. Nous proposons deux algorithmes d'analyse hiérarchique qui permettent de réduire le temps de calcul nécessaire pour analyser la robustesse de ces systèmes. Un avantage important de notre approche est la possibilité d'exécuter des parties de ces algorithmes de façon parallèle à chaque niveau hiérarchique ce qui diminuera de façon importante ce temps de calcul. Pour finir et dans le même contexte de système de grande dimension, nous nous intéressons à l'analyse de la performance dans les réseaux électriques et plus particulièrement «l'analyse du flux de puissances incertaines dans les réseaux électriques de distribution». Les sources d'énergies renouvelables comme les éoliennes et les panneaux solaires sont influencées par plusieurs facteurs : le vent, l'ensoleillement, etc.. Les puissances générées par ces sources sont alors intermittentes, variables et difficiles à prévoir. L'intégration de telles sources de puissance dans les réseaux électriques influencera les performances en introduisant des incertitudes sur les différentes tensions du réseau. L'analyse de l'impact des incertitudes de puissances sur les tensions est appelée «analyse du flux de puissances incertaines». La détermination de bornes sur les modules des différentes tensions est formulée comme un problème d'optimisation convexe sous contraintes LMI
This PhD thesis concerns robustness analysis (stability and performance) of uncertain large scale systems with hierarchical structure. These systems are obtained by interconnecting several uncertain sub-systems through a hierarchical topology. Robustness analysis of these systems is a two aspect problem: robustness and large scale. The efficient resolution of this problem using usual approaches is difficult, even impossible, due to the high complexity and the large size of the associated optimization problem. The consequence of this complexity is an important increase of the computation time required to solve this optimization problem. In order to reduce this computation time, the existing results in the literature focus on particular classes of uncertain linear large scale systems. Furthermore, the hierarchical structure of the large scale system is not taken into account, which means, from our point of view, that these results have several limitations on different levels. Our objective is to exploit the hierarchical structure to obtain a set of small scale size optimization problems instead of one large scale optimization problem which will result in an important decrease in the computation time. Furthermore, another advantage of this approach is the possibility of solving these small scale optimization problems in the same time using parallel computing. In order to take into account the hierarchical structure, we model the uncertain large scale system as the interconnection of uncertain sub-systems which themselves are the interconnection of other uncertain sub-systems, etc.. This recursive modelling is performed at several hierarchical levels. In order to reduce the representation complexity of uncertain systems, we construct a basis of dissipativity properties for each uncertain sub-system at each hierarchical level. This basis contains several elements which characterize different useful information about uncertain system behaviour. Examples of such characterizations are: uncertain phase characterization, uncertain gain characterization, etc.. Obtaining each of these elements is relaxed as convex or quasi-convex optimization problem under LMI constraints. Robustness analysis of uncertain large scale systems is then performed in a hierarchical way by propagating these dissipativity property bases from one hierarchical level to another. We propose two hierarchical analysis algorithms which allow to reduce the computation time required to perform the robustness analysis of the large scale systems. Another key point of these algorithms is the possibility to be performed in parallel at each hierarchical level. The advantage of performing robustness analysis in parallel is an important decrease of the required computation time. Finally and within the same context of robustness analysis of uncertain large scale systems, we are interested in robustness analysis of power networks and more precisely in "the uncertain power flow analysis in distribution networks". The renewable energy resources such as solar panels and wind turbines are influenced by many factors: wind, solar irradiance, etc.. Therefore, the power generated by these resources is intermittent, variable and difficult to predict. The integration of such resources in power networks will influence the network performances by introducing uncertainties on the different network voltages. The analysis of the impact of power uncertainties on the voltages is called "uncertain power flow analysis". Obtaining the boundaries for the different modulus of these voltages is formulated as a convex optimization problem under LMI constraints
