Resumo: A teoria local de curvas da Geometria Diferencial no plano e no espaço euclidiano é bem conhecida (vide referências como [4] e [13]). Este trabalho consiste de uma generalização desta teoria usando métricas arbitrárias. Tal generalização é feita substituindo a matriz identidade que define o produto interno usual por outra matriz quadrada, simétrica e positiva definida. Com este novo produto interno, são estudados conceitos como vetor tangente, vetor normal, vetor binormal, fórmulas de Frenet, curvatura e torção
Abstract: The local theory of curves of the Differential Geometry in the Euclidean plane and euclidean space is well known (see references as [4] and [13]). This work consists of a generalization of this theory using arbitrary metrics. Such generalization is made replacing the identity matrix which defines the usual inner product with another square matrix, symmetrical and positive defined. With this new inner product, concepts like tangent vector, normal vector, binormal vector, Frenet's formulas, curvature and torsion are studied

Full textThe purpose of this thesis is to investigate protein folding, by means of the general concepts of gauge invariance and universality. The gauge structure emerges in the Frenet equation which is utilized to describe the shape of protein backbone. The gauge invariance principle leads us an effective energy functional for a protein, which bas been found to catch the universal properties of folded proteins in their collapse phase,characterized by the scaling law of gyration radius on the tertiary level of proteinstructure. In this thesis, the existence of wide universality on the secondary level of protein structure is investigated. The synthesis of the gauge-invariant energy functional with the discrete Frenet equation leads to a soliton solution, which is identified as the helix-loop-helix motif in protein

This paper proposes to make use of GeoGebra Software as a tool in the study of flat curves. The Software was chosen because it is a powerful tool in teaching learning at all levels of Mathematics because it works with Algebra and Geometry, allowing the user to perform algebraic and graphical operations in the same interface. The topics covered include the parameterized flat curves up to the study of the Frenet benchmark, making Geogebra an important tool for the study and visualization of the concepts covered. With the help of the Software we can better analyze the curves through their graphs.

O objetivo deste trabalho é explorar os potenciais teóricos do conceito de aceleração social desenvolvido por Hartmut Rosa, no sentido do diagnóstico que este elabora sobre a experiência do tempo na contemporaneidade, derivando daí um modelo crítico particular. Deste diagnóstico busca-se ressaltar uma nova formação subjetiva, cujas tendências imanentes convergem para a crescente difusão de psicopatologias, que, por sua vez, reconfiguram o mal-estar na cultura. O caminho entre a teoria da aceleração social e o delineamento destas tendências se faz em três capítulos. No primeiro, o conceito de estabilização dinâmica é tomado como ordenador expositivo das categorias analíticas utilizadas por Rosa para constituir sua teoria fundamental e, com ela, fundar uma nova leitura do conceito de modernidade. No segundo são expostos os fenômenos que indicam, para Rosa, o ponto de viragem da modernidade para a modernidade tardia, e a partir deles elabora-se a base fenomênica das novas modalidades de integração social e das novas estratégias subjetivas que as acompanham. Por fim, no terceiro capítulo realiza-se uma reflexão sociológico-filosófica acerca do conceito de alienação derivado da teoria da aceleração social, e que denota uma estrutura patológica da subjetividade contemporânea. Da exposição deste conceito, elaborada em três instâncias, constituem-se os traços para um modelo crítico fundado no sofrimento implicado pela predicação das ações pela lei da aceleração social.
This work aims at exploring the theoretical potentials of the concept of social acceleration developed by Hartmut Rosa, towards the current time experience diagnosis he has elaborated, deriving from this a particular critical model. Departing from this diagnosis a new subjectivity formation is attempted to be highlighted, whose inner trends points to the spreading diffusion of psychopathologies which, by its turn, reset the culture discontent. The way between the theory of social acceleration and the drawing of these new tendencies is made by three chapters. In the first one, the concept of dynamic stabilisation is taken as an exposition organizer of the analytical categories used by Rosa in order to build its base theory and, with it, to ground a new reading of the modernity concept. In the second, there are exposed the phenomena that indicates, in Rosa’s view, the turning point between modernity and late-modernity, and from them the phenomenological base of new social integration modalities and its following subjective strategies is elaborated. Finally, at the third chapter, a sociological-philosophical reflection on the concept of alienation derived from the social acceleration theory, which denotes a pathological structure of the contemporary subjectivity, is operated. From this concept exposition, detailed in three dimensions, the traces of a critical model, grounded on the suffering caused by the prediction of the actions by the social acceleration law, is constituted.

Phua, Gailene. "Estimation of geometric properties of three-component signals for condition monitoring." Thesis, Université Grenoble Alpes (ComUE), 2016. http://www.theses.fr/2016GREAT004.
Full textMost methods for condition monitoring are based on the analysis and characterization of physical quantities that are three-dimensional in nature. Plotted in a three-dimensional Euclidean space as a function of time, these quantities follow a trajectory whose geometric characteristics are representative of the state of the monitored system. Usual techniques of condition monitoring study the measured quantities component by component, without taking into account their three-dimensional nature and the geometric properties of their trajectory. A significant part of the information is thus ignored. In this research work, we would therefore like to develop a method for the analysis and processing of three-component quantities capable of highlighting the special geometric features of such data and providing complementary information for condition monitoring. The proposed method has been applied to two different cases: voltage dips monitoring in three-phase power networks and bearing faults monitoring in rotating electrical machines. In this two cases, the results obtained are promising and show that the estimated geometric indicators lead to complementary information that can be useful for condition monitoring

A teoria local de curvas da Geometria Diferencial no plano e no espaço euclidiano é bem conhecida (vide referências como [4] e [13]). Este trabalho consiste de uma generalização desta teoria usando métricas arbitrárias. Tal generalização é feita substituindo a matriz identidade que define o produto interno usual por outra matriz quadrada, simétrica e positiva definida. Com este novo produto interno, são estudados conceitos como vetor tangente, vetor normal, vetor binormal, fórmulas de Frenet, curvatura e torção

Full textThe main aim of this work is a study about twistings points and Darboux vertices of n-space curves. We define the concept of twisting of a n-space curve as flattening point of its tangent indicatrix and show that is equivalent to having higher order of contact with some generalized helix. In the three dimensional case we establish a relation between twisting points and Darboux vertices. We also obtain a version of the four vertex theorem for space closed curves involving such points.
O presente trabalho destina-se a um estudo sobre pontos helicoidais (twistings) e vértices de Darboux de curvas no espaço euclidiano n-dimensional. Pontos helicoidais são pontos de aplainamento (flattening) da indicatriz tangente da curva. Mostramos que nestes pontos a curva tem maior contato com alguma hélice generalizada. No caso de curvas no espaço tridimensional, estabelecemos uma relação entre pontos helicoidais e vértices de Darboux. Obtemos também uma versão do teorema dos quatro vértices para curvas fechadas no espaço envolvendo tais pontos.

The oromaxillofacial complex is frequently envolved by diseases and variations from normality, some of which closely related to ethnical and racial groups. Studies on the distribution of oral diseases and variations from normality in Indian communities are generally directed mainly to the study of dental caries in the children and periodontal diseases in the adults, disregarding a wide range of other oral diseases. Thus, the aim of this study was to evaluate the oral health conditions of eight ethnic groups living in the Umutina Indian Reservation, in the State of Mato Grosso, Brazil. The total of 291 Indians, of both generes, with ages ranging from 1 to 96 years, were examined and were found between them 132 abnormalities and/or oral diseases, evidencing a high occurrence of ankyloglossia, which was present in 108 cases (37.11%), followed by benign migratory glossitis in 5 cases (1.72%); mandibular torus and candidosis in 3 cases (1.03%) among others. No malign lesion was identified in that population. Even thought the high frequency of the ankyloglossia in the ethnicities living in the Umutina Indian reservation, it does not seem to be responsible for alterations associated to phonation, mastication, presence of diastema and periodontal problems, since those alterations were observed with a low frequency and were not reason for complaint from the population. The dental conditions were evaluated with the aim to identify the prevalence of dental caries and the need of dental treatment in children from Umutina Village using a transversal epidemiological study. To analyze dental caries prevalence the decayed, missing, and filled teeth (DMFT) or decayed, extracted, and filled teeth (deft) indexes were used for, respectively, permanent or primary dentition and the need of treatment index.

Full textThe aim of this study was to validate the lingual frenulum Protocol for infants. Based on the results from the sample size calculation, the protocol was administered to 100 healthy full-term infants, who were being exclusively breastfeed, at 30 days of life. The validation process included the analysis of content validity, criterion validity, construct validity, reliability, sensitivity, specificity, positive predictive value, negative predictive value. The content validity was determined by the judgment of three experts, who rated the clarity of each item, and by a Content Validity Index (CVI) determination. By consensus, the examiners suggested some modifications for the final version. The criterion validity was measured by comparing the Lingual Frenulum Protocol for Infants and the Bristol Tongue Assessment Tool (BTAT). The construct validity was performed by comparing the scores of the protocol of the control group and of the experimental group before and after surgery. The assessments were performed by two Speech Language Pathologists, experienced in Orofacial Motricity (A1 and A2), who were trained and calibrated. Analyses of the images collected during the administration of the protocol and the clinical history were performed in order to verify the agreement between the examiners as well as the definition of sensitivity, specificity, positive predictive value, and negative predictive value. Intra-rater agreement analysis was performed by comparing data from assessment and re-assessment of 20% sample conducted by A2. Regarding statistical treatment, the Intraclass Correlation Coefficient (ICC) and calculation of error of method were used. The Wilcoxon test and Mann-Whitney were used for the analysis of the construct validity. The significance level of 5% (p<0.05) was adopted in all analyses. The agreement percentage for content validation was 100%. The criterion validity demonstrated strong correlation of the corresponding items of the lingual frenulum Protocol for infants and BTAT (Spearmans value = -0.997). The results demonstrated very good inter and intra-rater agreement with low values of random error and p>0.05 (indicating that there is no difference between the analysis of the evaluators) and Intraclass Correlation Coefficient was greater than 0.75. Moreover, the results indicated that the protocol clinical history, anatomo-functional evaluation, nutritive and non-nutritive suction has a significant capacity to assess changes after lingual frenotomy (p<0.05). Comparison of the results from the assessment of infants with lingual frenulum alteration (experimental group) and without lingual frenulum alteration (control group) at 30 and 75 days demonstrated the difference in both, the partial scores and total scores of clinical examination and full protocol. The values of sensitivity, specificity, positive predictive value, negative predictive value were 100%. Lingual frenulum alteration occurrence in this research was 21%. The study concluded that the lingual frenulum Protocol for Infants has demonstrated to be a valid and reliable assessment tool, ensuring accuracy to diagnose lingual frenulum alterations within the investigated parameters. It may be administered by other professionals provided that they are qualified and trained to administer the protocol.

Full textFocused on the theme of the “heroic frenzy” developed in Giordano Bruno’s last opus written in Italian language, De gli eroici furori (1585), this work explores a double issue from two perspectives. On the one hand, from an historical point of view, what are the philosophical schemes that may be considered as conditions of possibility for the emergence of the Furioso’s figure, the philosopher-poet whose poems and their commentary lead through a path of affects and knowledge in his own intellectual pursuit of a natural and rational bonding with the infinite principle of reality? Following an archeological method, specific and exemplary traces of these fundamental schemes are found within layers of philosophical culture, throughout works of authors of Antiquity, Middle Ages or Renaissance who set, relayed and modified them. On the other hand, from a conceptual point of view, the process of the Furioso’s psychological experience is studied. His both noetic and loving encounter with the Principle is never completely fulfilled because of the disproportion between “the subject” and “the object”. Nevertheless, it is presented as a dissolution of self by ending the distinction between the subject and the object. How does this experience paradoxically implements a constitution of self?

Full textThis thesis consists of two parts: a creative project, entitled Frenzy: The Story of the Mount Rennie Outrage, and a dissertation, entitled No end of a yarn: Reading the Mount Rennie Outrage. The first part is a narrative history of events that occurred in Sydney over a period of four months, from 9th September 1886, when 16-year-old Mary Jane Hicks was raped by members of a larrikin mob near Waterloo, until 8th January 1887, when four of the teenage rapists were hanged. Most of the material I have researched to write this history is derived from three key sources: original records of the crime and subsequent trial held at State Records in Western Sydney; original records from the archives of the New South Wales Department of Corrective Services at Silverwater Jail; and contemporary newspaper reports held in various forms at the State Library of New South Wales. My dissertation is a study of how the Outrage has been interpreted, both directly and indirectly, by participants, journalists, politicians, novelists and others. It suggests the existence of two contradictory impulses - a desire to sensationalise the facts and a contrary desire to suppress them – that, to varying degrees, have shaped every reading of the Outrage. It examines these impulses in the light of social and sexual anxieties of the period as reflected, especially, in journalism and popular fiction. It proposes two “authorised” readings of the case — as the tragedy of Mary Jane Hicks or, alternatively, as the tragedy of the youths hanged or imprisoned for raping her — and asks whether other, more flexible, interpretations are possible. It ends with some reflections about the wider processes by which history is read and written.

Full textObjectives To deepen the knowledge of the use of the laser in dental medicine / pediatric dentistry. The main focus is the frenectomy using the laser, comparing it with the conventional technique. Material and Methods The literature review was based on a bibliographical research of articles published in scientific journals available in electronic databases. We included articles that related the use of the laser in frenectomy, published between 2000 and 2018 only in Spanish, English and Portuguese. Development The laser was introduced in dentistry with the aim of overcoming some of the disadvantages imposed by conventional methods. Laser therapy is an innovative resource for an effective preventive and therapeutic strategy in pediatric dentistry. The oral braces often present changes in shape, constitution and insertion, and in these cases, sometimes, a frenectomy is necessary. Laser is a good alternative to conventional surgery.

Full textThis work was developed with the aim to study the local properties of curves and surfaces, in the euclidean space, through their parametrizations. We described the shape of a curve through its curvature and torsion. Next, we analysed several methods of obtaining new curves from an original curve, namely the evolute, involute, pedal, cissoid and conchoid of a curve. Concerning surfaces, its shape is described by Gaussian and mean curvatures. Additionally, concerning curves contained in surfaces, its shape is described through normal, geodesic and principal curvatures. Geodesics are approached as curves contained in a surface, minimizing the distance between two points on the surface. It should also be pointed out that due to the difficulty and scarcity of visualization of such parametrizations in the literature, it was intended throughout this work to exemplify each case graphically.

Full textINTRODUÇÃO: A estética pessoal assume atualmente um papel importante nos aspetos sociais, emocionais e profissionais. A presença de diastemas nos dentes anteriores pode estar associada a um impacto negativo na estética do sorriso e na fonação. O conhecimento detalhado da morfologia dentária e periodontal associada aos diastemas é fundamental para a elaboração e previsibilidade do eventual plano de tratamento.OBJECTIVO: Caracterização do morfotipo dentário e periodontal associado à presença de diastemas no 2º sextante de jovens adultos, particularmente na correlação da presença de diastemas com a morfologia dos tecidos periodontais.METODOLOGIA: Foram selecionados 22 pacientes, 11 com diastemas (Grupo 1) e 11 sem diastemas nem apinhamento (Grupo 2). Em todos foi realizado um exame oral completo, uma história clinica, um protocolo fotográfico, impressões convencionais e digitais, radiovisiografias e uma tomografia de feixe cónico de modo a determinarem-se alguns dos componentes da morfologia dentária e periodontal destes pacientes. Além das medições analógicas directas e digitais, foram também efetuadas medições com recurso a programas informáticos de integração, análise e coorelação de dados digitais. Foi utilizado o IBM SPSS Statistics 23.0 para executar a análise estatística. A normalidade da distribuição foi avaliada pelo teste de Shapiro-Wilk e as diferenças médias entre os grupos avaliados com o t-test. A correlação de Pearson foi usada para avaliar a correlação entre as variáveis escalares. O nível de significância foi fixado em 0,05.RESULTADOS: No grupo 1, a distância média entre a crista óssea e a papila no diastema mediano foi de 4,18mm± 0,64 e a distância média entre a papila e o zenith é 4,49mm±0,81. No grupo 2, a distância média entre a crista óssea e a papila no diastema mediano foi 3,75mm± 0,38 e a distância média entre a papila e o zenith de 3,97mm±0,63. Em ambos, 90% dos pacientes apresentaram um padrão regular ascendente de distribuição vertical das papilas no 2º sextante. Para estas 3 variáveis analisadas não se verificaram diferenças estatisticamente significativas entre os dois grupos.DISCUSSÃO e CONCLUSÕES: Dentro das limitações deste estudo, pode deduzir-se que, apesar das diferenças nas relações interdentárias nos pacientes com diastemas, o morfotipo periodontal não parece ter alterações relevantes relativamente aos pacientes sem diastemas. A posição e disponibilidade dos tecidos de suporte periodontais na zona dos diastemas não parece ser prejudicada pela existência de espaços interdentários.PALAVRAS-CHAVE: “Diastemas” , “Papila dentária”, “Osso alveolar”, “Dente anterior”, “Interdentária”, “Maturação da sutura média palatina”, “Freio Labial”
INTRODUCTION: Personal aesthetics nowadays play an important role in social, emotional and professional aspects. The presence of diastema in the anterior teeth may be associated with a negative impact on smile aesthetics and phonation. The detailed knowledge of the dental and periodontal morphology associated with diastemas is fundamental for the elaboration and predictability of an eventual treatment plan.OBJECTIVE: Description of the dental and periodontal morphotypes associated with the presence of diastema in the 2nd sextant of young adults, particularly in the correlation of the presence of diastema with periodontal tissue morphology.METODOLOGY: Were selected 22 patients, 11 with diastema (Group 1) and 11 with no diastemas or crowding (Group 2).. All participants were realized a full oral examination and filled a clinical history. Data collection was done using a digital photographic protocol, conventional prints, intra-oral fingerprints, radiovisiographies, and a conical beam tomography to determine some of the components of the dental and periodontal morphology of these patients through various analytical processes. Furthermore to direct and digital-analog measurements in some of the analysis methods, measurements were also made using digital data integration, analysis, and co-data processing software. IBM SPSS Statistics 23.0 was used to perform the statistical analysis. Normality of distribution was assessed with Shapiro-Wilk test and mean differences between groups evaluated with the t-test. Pearson correlation was used to assess correlation between scalar variables. Significance level was set at 0.05.RESULTS: In group 1, the mean distance between the crestal bone and the papilla in the median diastema was 4,18mm±0,64 and the mean distance between the papilla and the zenith was 4,49mm±0,81. In group 2, the mean distance between the bone crest and the papilla in the median diastema was 3,75mm± 0,38 and the mean distance between the papilla and the zenith was 3,97mm±0,63. In both groups, 90% of the patients had the regular ascending pattern of the vertical distribution of the papillae in the 2nd sextant.DISCUSSION and CONCLUSION: Within the limitations of this study, it can be deduced that, despite differences in interdental relationships in patients with diastemas, the periodontal morphotype does not appear to have relevant alterations regarding patients without diastema. The position and availability of periodontal support tissues in diastemas does not appear to be affected by the existence of interdental spaces.KEY – WORDS : “Diastema”, “Dental Papilla”, “Alveolar bone”, “Anterior teeth”, “Interdental”, “Midpalatal suture maturation”, “Labial frenum”
