With respect to the continuous growth of computing systems, the energy-efficiency requirement of their processes becomes even more important. Different configurations, implying different energy-efficiency of the system, could be used to perform the process. A configuration denotes the choice among different hard- and software settings (e.g., CPU frequency, number of threads, the concrete algorithm, etc.). The identification of the most energy-efficient configuration demands to benchmark all configurations. However, this benchmarking is time- and energy-consuming, too. This thesis explores (a) the effect of dynamic voltage and frequency scaling (DVFS) in combination with dynamic concurrency throttling (DCT) on the energy consumption of (de)compression, DBMS query executions, encryption/decryption and sorting; and (b) a generic approach to reduce the benchmarking efforts to determine the optimal configuration. Our findings show that the utilization of optimal configurations can save wavg. 15.14% of energy compared to the default configuration. Moreover, we propose a generic heuristic (fractional factorial design) that utilizes data mining (adaptive instance selection) together with machine learning techniques (multiple linear regression) to decrease benchmarking effort by building a regression model based on the smallest feasible subset of the benchmarked configurations. Our approach reduces the energy consumption required for benchmarking by 63.9% whilst impairing the energy-efficiency of performing the computational process by only 1.88 pp, due to not using the optimal but a near-optimal configuration.

Les formes d'organisations industrielles sont en évolution en raison d'une désintégration verticale de l'entreprise. Ces évolutions rendent indispensables des formes de régulation de la relation client/fournisseur. En parallèle, les entreprises sont incitées à se positionner par rapport à des enjeux environnementaux et sociaux.<br />L'éthique de l'entreprise satisfait une demande de repérage et d'affirmation de règles communes relatives à la sphère économique. La formalisation de l'éthique permet à la firme de l'intégrer à ses politiques. Les normes éthiques, outils spécifiques de formalisation, établissent un compromis entre la recherche d'une attitude responsable, un état de la technique et les contraintes économiques. L'intérêt porté aux normes éthiques se justifie par le fait qu'elles représentent des modes de régulation originaux des relations inter-entreprises sur le plan de la coordination et des échanges. Trois caractéristiques de ces normes sont à mettre en perspective : elles sont de nature hétérogène, en plein foisonnement et traduisent une régulation de la sphère privée par elle-même. Dans ce contexte l'éthique de l'entreprise est loin d'être neutre en termes de régulation des fournisseurs et des sous-traitants et plus généralement en termes de rôle de l'entreprise dans la société. L'utilisation de ces normes éthiques révèle une segmentation entre des fournisseurs primaires et secondaires. Les normes éthiques créent de la confiance pour certains et instrumentent la dépendance pour d'autres. Ces pratiques sont confirmées dans une perspective institutionnelle par les modes de construction des normes et les zones d'influence qu'elles créent. Les entreprises, les Etats et les organisations internationales interviennent dans la structuration de l'architecture internationale de la normalisation éthique. Cette architecture révèle le pouvoir structurel de la normalisation en tant que moyen de régulation des relations inter-firmes et du capitalisme.

Business process automation improves organizations’ efficiency to perform work. In existing business process management systems, process instances run independently from each other. However, synchronizing instances carrying similar characteristics, i.e., sharing the same data, can reduce process execution costs. For example, if an online retailer receives two orders from one customer, there is a chance that they can be packed and shipped together to save shipment costs. In this paper, we use concepts from the database domain and introduce data views to business processes to identify instances which can be synchronized. Based on data views, we introduce the concept of batch regions for a context-aware instance synchronization over a set of connected activities. We also evaluate the concepts introduced in this paper with a case study comparing costs for normal and batch processing. / Die Automatisierung von Geschäftsprozessen unterstützt Unternehmen, die Ausführung ihrer Prozesse effizienter zu gestalten. In existierenden Business Process Management Systemen, werden die Instanzen eines Prozesses völlig unabhängig voneinander ausgeführt. Jedoch kann das Synchronisieren von Instanzen mit ähnlichen Charakteristiken wie z.B. den gleichen Daten zu reduzierten Ausführungskosten führen. Zum Beispiel, wenn ein Onlinehändler zwei Bestellungen vom selben Kunden mit der gleichen Lieferanschrift erhält, können diese zusammen verpackt und versendet werden, um Versandkosten zu sparen. In diesem Papier verwenden wir Konzepte aus dem Datenbankbereich und führen Datensichten für Geschäftsprozesse ein, um Instanzen zu identifizieren, welche synchronisiert werden können. Auf Grundlage der Datensichten führen wir das Konzept der Batch-Regionen ein. Eine Batch-Region ermöglicht eine kontext-bewusste Instanzen-Synchronisierung über mehrere verbundene Aktivitäten. Das eingeführte Konzept wird mit einer Fallstudie evaluiert, bei der ein Kostenvergleich zwischen der normalen Prozessausführung und der Batchverarbeitung durchgeführt wird.

In this work we developed rule-based algorithms for multiple-instance learning and one-class learning problems, namely, the mi-DS and OneClass-DS algorithms. Multiple-Instance Learning (MIL) is a variation of classical supervised learning where there is a need to classify bags (collection) of instances instead of single instances. The bag is labeled positive if at least one of its instances is positive, otherwise it is negative. One-class learning problem is also known as outlier or novelty detection problem. One-class classifiers are trained on data describing only one class and are used in situations where data from other classes are not available, and also for highly unbalanced data sets. Extensive comparisons and statistical testing of the two algorithms show that they generate models that perform on par with other state-of-the-art algorithms.

Resume Title of this thesis: Proceedings for administrative infractions in the first instance. The thesis deals with administrative infraction proceedings in the first instance, mainly about the steps of administrative office before instituting the administrative proceedings. It is based on the new scholarly literature, incorporates new judicature and takes account of methodologies of Ministry of the Interior and practical problems. In the chapter I there are defined administrative infraction proceedings, its relation to Administrative proceedings Act and the infraction and there is also described the basic character of the proceedings for administrative infractions in the first instance. In the chapter II there is described competence of administrative office in administrative infraction proceedings, namely subject-matter jurisdiction, local jurisdiction and function competence. It deals with the changes of these competences too. Furthermore, in this context the thesis deals with professional competence of persons in authority and with contracts under public law. In the last part there are mentioned the reasons for exclusion of administrative persons, above all from bias. In the chapter III there is explained the purpose of steps before instituting the administrative proceedings. First, it describes the...

A sequência de protestos em junho de 2013 sacudiu o cenário político brasileiro como um terremoto - foram manifestações que começavam e terminavam nas telas. Além de matéria-prima para imagens, as passeatas também como imagens sociais (dependem do olhar social) e itinerantes (para adquirir valor e significado), fundando uma nova visibilidade. Para apreender a dimensão desses eventos na instância da imagem ao vivo, foi analisada a edição especial do Jornal Nacional do dia 20 de junho daquele ano. Nos resultados, obtidos por meio da técnica da análise de conteúdo, é notório o adestramento do olhar que, insensível, olhou a multidão de uma perspectiva superior. / The series of protests in June 2013 has changed Brazilian political scenery in an abrupt way as an earthquake - the demonstrations began and ended on the television screens. More than base for images, the riots constitute social images (which depend on the social point of view) and are itinerant (to form value and meaning). To comprehend the dimension of these events in the context of instance of the live image, this work studies, by content analyses approach, the special edition of Jornal Nacional in the 20th June 2013. The results show that the point of view of the imagetic speech is cold, unsympathetic and arrogant towards the protesters.

Aprendizado múltipla instância (MIL) é um paradigma de aprendizado de máquina que tem o objetivo de classificar um conjunto (bags) de objetos (instâncias), atribuindo rótulos só para os bags. Em MIL apenas os rótulos dos bags estão disponíveis para treinamento, enquanto os rótulos das instâncias são desconhecidos. Este problema é frequentemente abordado através da seleção de uma instância para representar cada bag, transformando um problema MIL em um problema de aprendizado supervisionado padrão. No entanto, não se conhecem abordagens que apoiem o usuário na realização desse processo. Neste trabalho, propomos uma visualização baseada em árvore multi-escala chamada MILTree que ajuda os usuários na realização de tarefas relacionadas com MIL, e também dois novos métodos de seleção de instâncias, chamados MILTree-SI e MILTree-Med, para melhorar os modelos MIL. MILTree é um layout de árvore de dois níveis, sendo que o primeiro projeta os bags, e o segundo nível projeta as instâncias pertencentes a cada bag, permitindo que o usuário explore e analise os dados multi-instância de uma forma intuitiva. Já os métodos de seleção de instãncias objetivam definir uma instância protótipo para cada bag, etapa crucial para a obtenção de uma alta precisão na classificação de dados multi-instância. Ambos os métodos utilizam o layout MILTree para atualizar visualmente as instâncias protótipo, e são capazes de lidar com conjuntos de dados binários e multi-classe. Para realizar a classificação dos bags, usamos um classificador SVM (Support Vector Machine). Além disso, com o apoio do layout MILTree também pode-se atualizar os modelos de classificação, alterando o conjunto de treinamento, a fim de obter uma melhor classificação. Os resultados experimentais validam a eficácia da nossa abordagem, mostrando que a mineração visual através da MILTree pode ajudar os usuários em cenários de classificação multi-instância. / Multiple-instance learning (MIL) is a paradigm of machine learning that aims at classifying a set (bags) of objects (instances), assigning labels only to the bags. In MIL, only the labels of bags are available for training while the labels of instances in bags are unknown. This problem is often addressed by selecting an instance to represent each bag, transforming a MIL problem into a standard supervised learning. However, there is no user support to assess this process. In this work, we propose a multi-scale tree-based visualization called MILTree that supports users in tasks related to MIL, and also two new instance selection methods called MILTree-SI and MILTree-Med to improve MIL models. MILTree is a two-level tree layout, where the first level projects bags, and the second level projects the instances belonging to each bag, allowing the user to understand the data multi-instance in an intuitive way. The developed selection methods define instance prototypes of each bag, which is important to achieve high accuracy in multi-instance classification. Both methods use the MILTree layout to visually update instance prototypes and can handle binary and multiple-class datasets. In order to classify the bags we use a SVM classifier. Moreover, with support of MILTree layout one can also update the classification model by changing the training set in order to obtain a better classifier. Experimental results validate the effectiveness of our approach, showing that visual mining by MILTree can help the users in MIL classification scenarios.

The aim of my thesis is to demonstrate the potential of eXtensible Business Reporting Language in the field of corporate reporting and data exchange. XBRL is still little known in the Czech Republic; that is why the first part of the work focuses primarily on the explanation of the basic principles on which this language is founded. Further, the functionality of applications for working with XBRL will be described, followed by an analysis of the benefits that this language can bring to its users. The thesis also covers various approaches that the reporting companies can use when implementing XBRL and analyzes the areas suitable for the introduction of XBRL in the Czech Republic. The last part of the work describes the practical experience with the creation and subsequent use of XBRL instance documents.

Qualification work is focused on problematic of injuries, occurring in the population, and their influence regarding amount of costs covered by the public health care. The aim of this thesis is to determine, based on available information, expenses trends in health care and also costs, related to health care, of individual health insurance companies. Identification of injuries occurrence throughout the population and determination of their costs and complexity is furthermore important segment of the thesis. Based on these data, the objective of this thesis is to identify the portion of this amount contributing to the overall costs of public health care. The practical part of the thesis also contains analysis of recommendations, which might influence or cause change from current situation.

Un justiciable mécontent lève un rideau, sans doute usé. Une robe noire apparaît alors et énonce: « Donne moi le fait, je te donnerai le droit ! ». Ce juge s’écarte ensuite afin d’écouter les échanges des parties. Il reprend la parole, reformule le cas échéant certaines répliques et démêle l’intrigue en retenant, voire aménageant, une des fins proposées par les parties. Voici la trame, désormais classique, de l’instance dressée par les principes directeurs du procès civil. Les plaideurs auraient ainsi pour rôle de délimiter la matière litigieuse et, partant, la saisine du juge. Ce dernier devrait, dans les limites ainsi tracées, lui appliquer le droit afin de satisfaire à sa fonction juridictionnelle. La question des rôles respectifs du juge et des parties sur les éléments de l’instance ne saurait toutefois être appréhendée dans sa complexité et son dynamisme par ces seules règles. La distinction du fait et du droit, parce qu’elle ne correspond qu’imparfaitement aux éléments de l’instance réellement opérant, la prétention et le moyen, offre une assise peu opportune à la détermination des activités judiciaires et leur exercice. Par ailleurs, lorsqu’ils sont confrontés à la réforme permanente de la matière, la stabilité de ces principes interpelle, et étonne même.En considérant les éléments de l’instance et leur traitement au-delà des dispositions préliminaires du code, et au-delà du code lui-même, il pourra être énoncé que ces principes directeurs tendent à devenir davantage aveuglants qu’éclairants. En effet à la lecture de l’article 12 du Code de procédure civile, fondement des pouvoirs et devoirs du juge sur le droit, il est par exemple établi que le juge tranche le litige conformément aux règles de droit qui lui sont applicables. On ignore ainsi que, depuis 2008, le juge n’a pas l’obligation de rectifier le fondement juridique erroné de la demande, comme on ne se doute pas plus que son obligation de statuer se limitera, depuis 2017, aux seules prétentions contenues dans le dispositif des dernières conclusions, certes rédigées par avocat. On n’anticipe encore moins que, en dépit de tous ces phénomènes de réduction de ce qui devra être tranché, l’autorité de chose jugée va, quant à elle, au contraire, s’étendre pour couvrir le litige entendu comme tout ce qui aurait dû être tranché. Les parties recueillent ainsi la charge du droit initialement dévolue au juge. La procédure civile offre dès lors un nouveau visage au principe dispositif : la responsabilisation des parties et la déresponsabilisation de la justice dans la réalisation des droits.L’accélération du traitement des affaires rapproche l’instance civile du théâtre par l’exigence de l’unité de temps. Elle s’en éloigne en revanche s’agissant de la règle de l’unité de lieu, les politiques judiciaires affichant clairement leur volonté de promouvoir le règlement amiable des litiges. Il n’y a plus qu’à espérer que la distribution soit à la hauteur du programme. / A displeased person answerable to the law raises a curtain, most likely worn out. A black robe appears and announces: ‘Give me the facts, I will give you the law!” This judge then steps aside in order to listen to the exchanges between various parties. He speaks again, change when required some turn of sentences, untangle the plot by retaining, even rearranging one of the ending proposed by the parties. Here is the context, now classic, of the instance established by the guidelines of civil trial. The role of the litigant is thus to delimit the litigious matter and hence, the referral to the judge. The latter should, within the limits, apply to him the law in order to satisfy his jurisdictional function. The question of the respective roles of the judge and the parties over the elements of the case cannot, however, be apprehended in its complexity and dynamism by these rules alone. The distinction between fact and law, because it corresponds only imperfectly to the elements of the actual operative instance, the claim and the plea, provides an unfavourable basis for the determination of judicial activities and their exercise. On the other hand, when confronted with the permanent reform of matter, the stability of these principles challenges, and even astonishes.By considering the elements of the case and their treatment beyond the preliminary provision of the Code, and beyond the Code itself it may be stated that these guiding principles tend to become more blinding than enlightening. Indeed, in reading Article 12 of the Code of Civil Procedure, the basis of the powers and duties of the judge on the law, it is for example established that the judge settle the dispute in accordance with the rules of law that apply to it. It is thus not known that since 2008 the judge has no obligation to rectify the erroneous legal basis of the claim, the same way we do not conceive that his obligation to rule will, since 2017, be limited to the claims contained in the device of the conclusions, admittedly written by lawyers. It is even less anticipated that, in spite of all these phenomena of reduction of what will have to be settled, res judicata will, on the contrary, extend to cover the dispute understood as all that should have been decided. The parties thus collect the burden of the right initially devolved on the judge. Civil procedure therefore offers a new face to the operative principle: the responsibility of the parties and the disempowerment of justice in the realization of rights.The acceleration of the treatment of the cases brings the civil authority closer to the theatre by the requirement of the unit of time. On the other hand, it departs from the rule of unity of place, as judicial policies clearly reflect their desire to promote the amicable settlement of disputes. There is more to hope that the distribution is up to the programme
