O monitoramento automático de pacientes é um recurso essencial em hospitais para o bom gerenciamento de cuidados médicos. Enquanto que alarmes devido a condições fisiológicas anormais são importantes para o rápido tratamento, estes também podem ser uma fonte de ruídos desnecessários devido a falsos alarmes causados por interferência eletromagnética ou movimentação de sensores. Uma fonte significativa de falsos alarmes é relacionada com a frequência cardíaca, o qual é disparado quando o ritmo cardíaco do paciente está muito rápido ou muito lento. Neste trabalho, a fusão de diferentes sensores fisiológicos é explorada para fazer uma estimativa robusta de frequência cardíaca. Um conjunto de algoritmos utilizando índice de variabilidade cardíaca, inferência bayesiana, redes neurais, lógica fuzzy e votador majoritário são propostos para fundir a informação do eletrocardiograma, pressão sanguínea e fotopletismograma. Três informações básicas são extraídas de cada sensor: variabilidade cardíaca, a diferença de frequência cardíaca entre os sensores e a análise espectral. Estas informações são usadas como entradas para os algoritmos. Quarenta gravações selecionadas do banco de dados MIMIC são usadas para validar o sistema. Finalmente, a frequência cardíaca calculada é comparada com as anotações do banco de dados. Resultados mostram que a fusão utilizando redes neurais apresenta a melhor redução de falsos alarmes de 89.33%, enquanto que a técnica bayesiana apresenta uma redução de 83.76%. A lógica fuzzy mostrou uma redução de 77.96%, o votador majoritário 61.25% e o índice de variabilidade cardíaca de 65.43%. Portanto, os algoritmos propostos mostraram bom desempenho e podem ser muito úteis em monitores de sinais vitais modernos. / Automatic patient monitoring is an essential resource in hospitals for good health care management. While alarms due to abnormal physiological conditions are important to deliver fast treatment, it can be also a source of unnecessary noise due to false alarms caused by electromagnetic interference or motion artifacts. One significant source of false alarms are those related to heart rate, which is triggered when the heart rhythm of the patient is too fast or too slow. In this work, the fusion of different physiological sensors is explored in order to create a robust heart rate estimation. A set of algorithms using heart rate variability index, bayesian inference, neural networks, fuzzy logic and majority voting is proposed to fuse information from electrocardiogram, arterial blood pressure and photoplethysmogram. Three basic informations are extracted from each source, namely, heart rate variability, the heart rate difference between sensors and the spectral analysis. These informations are used as inputs to the algorithms. Forty selected recordings from MIMIC database was used to validate the system. Finally, the calculated heart rate is compared with the database annotation. Results show that neural networks fusion presents the best false alarms reduction of 89.33%, while the bayesian technique presents an error reduction of 83.76%. Fuzzy logic showed an error reduction of 77.96%, majority voting 61.25% and the heart rate variability index 65.43%. Therefore, the proposed algorithms showed good performance and can be very useful for modern bedside monitors.

The optimized extraction condition for Jatropha gossypifolia was the binary mixture 1:1 chloroform:isopropanol, while to Jatropha multifida L. the mixture was ternary consisting of 2/3:1/6:1/6 ethanol:acetone:1,4-dioxane. The fingerprint chromatograms were runned using an exploratory gradient consisting of 5-100% of organic solvent, using a C-18 (5 µm) column, as stationary phase, and then the mobile phase was optimized, through the use of chemometrics for each species. In the case of Jatropha gossypifolia L. the phase consisted in a mixture of 68:32 MeOH:ACN, under a column temperature of 30 oC, injection volume of 30 µL and a flow of 2.0 mL.min-1. For Jatropha multifida L. was 1:1 MeOH:ACN, under column temperature of 40 oC, flow of 2,5 mL.min-1 and an injection volume of 30 µL. Some in vitro bioassays were performed, such as, reduction of the reagent DPPH (antioxidant action), inhibition of polymerization of the haematin bovine (antimalarial), enzymatic inhibition of the acetylcholinesterase (Alzheimer’s disease) and the assay of inhibition of the growth of phytopatogenic fungi. None of the crude extracts showed significant activities when compared to the used standards. The application of dereplication methods allowed the identification of some classes of compounds, already reported for Jatropha, such as terpenoids and flavonoids. The strategy developed to performed the dereplication, used an in silico approach through the matching and analysis of the spectrometric and spectroscopic data sets obtained using NMR and HPLC-HRMS(ESI)-MS2 with databases of high...

Following from its title, this diploma work discusses Gipsy culture and traditions, especially maps the level of knowledge comparing Gipsy and non-Gipsy inhabitants in the town of Tabor. The choice of the topic proceeds from a widely known fact involving the problematic common life of those too much different groups. Many members of the majority do not have any awareness of Gipsies being a specific group of inhabitants, having their own culture and traditions. On the other hand, the traditional life of the Gipsies has changed at all,rather has declined, especially in the field of language.Both these points of view may play an important role in one another understanding of the Gipsies and the majority. The target of my work was to map the knowledge of the Gipsy culture and traditions by the Gipsy commune and, as well, to map the knowledge of the majority. Within the framework of this, two main hypothesises were determined. The first main hypothesis assumed that the Gipsy commune in Tabor hadn´t known its tradition and culture any more. The second main hypothesis assumed that the majority hadn´t known the Gipsy tradition and culture. These two hypothesises weren´t proved because the decisive part of questioned people( both Gipsy and non-Gipsy) had known at least one element of Gipsy culture and tradition. Another important investigation was made in my work.They are specified in details in the part {\clqq}Discussion`` of my work. In consideration of the fact that nobody has ever occupied with this problem in the area of the town of Tabor, I suppose, that the points of my work may be useful for organizations that provide service for the Gipsy commune in Tabor.To make it possible, I am going to present my work on the web page of the town of Tabor.

Our Tyrannies. Tocqueville on Democratic Despotism”. Although thelexicon of tyranny” and despotism” is subject to historical changes in meaning,we still keep on using those terms to refer to some types of illegitimate, unjust orindecent political regimes. So does Tocqueville, when he describes the new waysof despotism emerging from modern democratic revolution. In this article, weexplore the uses of tyranny” and despotism” in Tocqueville’s thought, and wealso try to discover the concrete models or social prototypes which could inspireTocqueville’s prognosis concerning a tutelary democratic despotism. / Aunque el léxico de la tiranía” y el despotismo” está sujeto a cambios históricos de significado, seguimos utilizando esos términos para referirnos a algunos tipos de regímenes políticos ilegítimos, injustos o indecentes. También lo hace Tocqueville, cuando describe las nuevas vías del despotismo que surgen en la revolución democrática moderna. En este artículo, exploramos los usos de latiranía” y el despotismo” en el pensamiento de Tocqueville, y también intentamos descubrir los modelos concretos o los prototipos sociales que pudieron inspirarla prognosis de Tocqueville concerniente a un despotismo democrático tutelar.

Este trabalho procura compreender como funcionam as coalizões que sustentam o Executivo no Brasil, com um olhar direcionado ao processo legislativo, ou seja, à forma como leis são processadas no interior do Poder Legislativo. Acredito que a formação de coalizões implica na divisão de poder e de responsabilidade sobre o conjunto de políticas, ou seja, implica que todos os partidos que compõem a coalizão participam e influem no resultado final do processo decisório. Pretendo, através da análise do processo de produção das leis, identificar em que moldes se dá o acordo entre os partidos no tocante a políticas específicas. Privilegio as medidas introduzidas e vetadas pelo Executivo para, por meio destas, mostrar como se dá concretamente este acordo. / This work seeks to understand the coalitions that support the Executive Power in Brazil, focusing the legislative process, which means, focusing how the laws are produced inside the Legislative Power. The assumption is that forming coalitions implies sharing power and responsibilities over the broad set of policies. In other words, it implies that the parties composing the coalition participate and influence the results of the decisionmaking process. By analyzing the legislative process, the aim is to identify the terms of the parties agreement concerning policies. The emphasis is on the bills introduced and vetoed by the Executive, assuming that they reveal this agreement.

On the trails of this proposal there will be systematized 04 (four) analytical models, considered ideal types, and 02 (two) systematized models considered non-ideal types, besides; all presented as possible mechanisms to form parliamentary majority in pre sidential regimes. Such mechanisms will be compared to the grand allowance scandal experience with the aim to verify what of the Brazilian culture and sociability favors, that one of these mechanisms, the financial cooptation, presents itself as an alternative on the majority parliamentary formation, even if it is superimposed among the others. This study will be built up by bibliographic and documentary research. Taking those models as instruments for empirical analyses, there will be used a variety of r eading material with the purpose of understanding the parliamentary majority formation in Brazil in its most vast context, pursuing to reveal, for that, possible shades of the social and cultural structure of the country. For that, the research will use sc ientific works of sociology, political and historic science, appealing to the themes concerned to sociological and political theory, to Brazilian political culture and to the corruption / Ancorando-se empiricamente no episódio político que ficou conhecido como escândalo do mensalão , esta dissertação tem por proposta estudar o processo de formação de maioria parlamentar no Brasil atual. Nos trilhos desta proposta serão sistematizados 04 (quatro) modelos analíticos, tomados como tipos-ideais, além de outros 02 (dois) modelos sistematizados não como tiposideais; todos apresentados como mecanismos possíveis para se formar maioria parlamentar em regimes presidencialistas. Tais mecanismos serão contrapostos à experiência do esquema do mensalão com a finalidade de verificar o que da cultura e da sociabilidade brasileiras favorece que um desses mecanismos, a cooptação financeira, apresente-se como alternativa na formação de maioria parlamentar, mesmo que superposta às demais. O estudo será desenvolvido mediante pesquisa bibli ográfica e pesquisa documental. Tomando tais modelos como instrumentos pa ra análise empírica, serão utilizadas diversas obras com a proposta de compreender a formação de maioria parlamentar no Brasil a partir de seu contexto mais amplo, buscando desvelar, para isso, possíveis matizes da estrutura social e cultural do País. Para tanto, a pesquisa utilizará trabalhos nas áreas de Sociologia, Ciência Política e História, recorrendo aos temas vinculados à teoria política e sociológica, à cultura política brasileira e à corrupção

This thesis deals with selected institutes of the Act No. 340/2015 Coll, to Regulate the Register of Contracts (hereinafter as "the Act"). The unifying criterion is their impact on entrepreneurial entities stated in section 2 subsection 1 of the Act. Selected institutes of the Act are contracts and information published in the register of contracts, legal entities by section 2 subsection 1 paragraph n) of the Act, the business secret as an exception of an obligation of publication and an exception of an obligation to published contract by section 3 subsection 2 paragraph q) of the Act. The aim of this thesis is to characterize these institutes in more detail and to find out possible interpreting ambiguities that concern them. It also attemps to offer their solutions with regard to the relevant specialised literature. The thesis is systematically divided into an introduction, four parts and a conclusion. Parts are further subdivided into chapters, subchapters and subchapters's points. The first part discourses about contracts and information published in the register of contracts especially focusing on private law contracts. This part also analyses a term of metadata and a form of published contracts. The second part reports about legal entities stated in section 2 subsection 1 paragraph n) of the...

Sweden has one of the most sexually segregated labor markets in the world, which creates unbalanced working groups. In this paper we have analyzed women and men's experiences of a male dominated workplace in electricity industry. The purpose of the study was to analyze men and women's experiences of the male dominance in a workplace where women are in minority. The study also aimed to investigate the perceived organizational culture and whether the interviewees perceived that the workplace was equal. Previous research shows that male dominated workplaces create problematic working conditions for women in particular. Our study was based on semistructured interviews. Six people have been interviewed, of which as many women as men. The result of the study showed that the differences between men and women's experiences are relatively small. Both men and women was satisfied with their work situation, however it appears that women felt a greater need to prove themselves unlike men. Women and men agreed that the culture was perceived as hard and humorous, it differed depending on whether you worked in the office or out in the production.

The purpose of the present study is to investigate code-switching at a structural level among youths in Sweden speaking Persian. According to the theoretical framework of this essay code-switching occurs at certain places in sentences and follow certain grammatical rules. The aim of the conducted study is to demonstrate if there are word classes between which code-switches occur more frequently, whether or not it is possible to find out certain verbs that are borrowed from Swedish to Persian more often than others and if Persian compound verbs are often constructed with a Swedish main verb and the Persian light verb kardan. Eight students participated in the investigation and the ages of the participants varied from sixteen to nineteen years. The methods used consist of recorded interviews and elicitations and took place during a native language class. The result clearly showed that the most common word class from which switches from Swedishto Persian occurs is nouns. Among the verbs, the vast majority were compound verbs, constructed with a Swedish main verb and the Persian light verb kardan. Other light verbs used were raftan and xordan, however, these were only used one time each, implying that kardan is without doubtthe most common light verb used when building a Persian compound verb with a Swedish main verb. The present study does not indicate certain simple verbs used more often than others, on the contrary, it seems possible to choose almost any Swedish main verb in infinitive, or even a Swedish compound verb, and put it together with the Persian light verb kardan to form a Swedish/Persian compound verb.
