Orientador: Salatiér Buzetti / Resumo: As áreas de cultivo do eucalipto têm ocupado novas regiões do Brasil, sendo que o estado do Mato Grosso do Sul lidera esta expansão. Nessas novas áreas, a condição edafoclimática é um fator limitante ao desenvolvimento dessa cultura, pois os solos do bioma Cerrado apresentam baixa fertilidade natural, com pouca disponibilidade de fósforo (P) e potássio (K), e baixo teor de matéria orgânica (M.O.), além disso, o clima é caracterizado pela presença de déficit hídrico acentuado e frequente. Portanto, a carência de nutrientes no solo aliado às condições climáticas influenciam no desenvolvimento da cultura. Neste contexto, objetivou-se avaliar a adubação nitrogenada, fosfatada e potássica dado à importância desses nutrientes na cultura do eucalipto, e a suas limitações no solo em estudo. O experimento foi conduzido na Fazenda Renascença, fundo agrícola administrado pela Cargill Agrícola S/A, localizado no município de Três Lagoas/MS, de setembro de 2011 a julho de 2017, em um NEOSSOLO QUARTZARÊNICO Órtico. Utilizou-se o delineamento em blocos casualizados com quatro tratamentos e cinco repetições. Os tratamentos foram constituídos de doses de nitrogênio (N) (0, 70, 105 e 140 kg ha-1), de P (0, 40, 70 e 100 kg ha-1 de P2O5) e de K (0, 90, 135 e 180 kg ha-1 de K2O). Cada parcela foi composta por 56 plantas, distribuídas em sete linhas de oito plantas cada, totalizando 420 m2. Nas linhas de plantio, as mudas do clone I144 (Eucalyptus urophylla) foram espaçadas em 2,5 m e nas entrelin...

In these new areas, the soil and soil conditions of the Cerrado biome have low natural fertility, with low availability of phosphorus (P) and potassium (K), and low organic matter (OM), in addition, the climate is characterized by the presence of accentuated and frequent water deficit. Therefore, the lack of nutrients in the soil combined with climatic conditions influence the development of the crop. In this context, the objective was to evaluate the nitrogen, phosphate and potassium fertilization given to the importance of these nutrients in the eucalyptus crop and its limitations in the soil under study. The experiment was conducted at Fazenda Renascença, an agricultural fund managed by Cargill Agrícola S / A, located in the municipality of Três Lagoas / MS, from September 2011 to July 2017, in a Entisols. A randomized block design with four treatments and five replications. The treatments were composed rates of nitrogen (N) (0, 70, 105 and 140 kg ha-1), P (0, 40, 70 and 100 kg ha-1 P2O5) and K (0, 90, 135 and 180 kg ha-1 K2O). Each plot was composed of 56 plants, distributed in seven lines of eight plants each, totaling 420 m2. In the planting lines, the seedlings of clone I144 (Eucalyptus urophylla) were spaced at 2.5 m and in between lines at 3.0 m. The following were evaluated: wood productivity; nutrient concentrations in leaves; fo... (Complete abstract click electronic access below) / Doutor

Initially, we use the quadratic transmutation maps to compose a new probability model: the transmuted log-logistic distribution. Transmutation maps are a convenient way of constructing new distributions, in particular survival ones. It comprises the functional composition of the cumulative distribution function of one distribution with the inverse cumulative distribution (quantil) function of another. Its comprehensive description of properties, such as moments, quantiles, order statistics etc., along with its survival study and the classical and Bayesian estimation methods, are also part of this work. Focusing on analysis of survival, the study included two practical situations commonly found: the presence of regression variables, through the transmuted log-logistic regression model, and the presence of right censorship. In a second moment, searching for a more flexible model than the transmuted, we present its generalization, the transmuted distributions of cubic rank. Using the methodology presented in this first generalization, two models were considered to compose the new cubic transmuted distributions: the log-logistic and Weibull models. Faced with problems presented in the transmutated class of quadratic and cubic orders (such as the restricted parametric space of the transmutation parameter λ), we propose in this work, a new family of distribution. This family, which we call e-transmuted or e-extended, is as simple as the transmuted model, because it includes a single parameter to the base model, but more flexible than the class of transmuted models, once the transmuted is a particular case of the proposed family. In addition, the nem family presents important properties such as, orthogonality between the baseline model parameters and the e-transmutation parameter, along with unrestricted parametric space for the ω e-transmutation parameter, which is dened on the real line. Simulation studies and real data applications were performed for all proposed models and generalizations. / Inicialmente, usamos os mapas de transmutação quadráticos para compor um novo modelo de probabilidade: a distribuição log-logística transmutada. Mapas de transmutação são uma forma conveniente de construção de novas distribuições, em especial de sobrevivência/confiabilidade, e compreendem a composição funcional da função de distribuição acumulada e da função de distribuição acumulada inversa (quantil) de um outro modelo. Uma descrição detalhada de suas propriedades, tais como, momentos, quantis, estatística de ordem, dentre outras estatísticas, juntamente com o estudo de sobrevivência e métodos de estimação clássico e Bayesiano, também fazem parte deste trabalho. Focando em análise sobrevivência, incluímos no estudo duas situações práticas comumente encontradas: a presença de variáveis regressoras, através do modelo de regressão transmutado log-logístico, e a presença de censura à direita. Em um segundo momento, buscando um modelo mais flexível que o transmutado, apresentamos uma generalização para esta classe de modelos, as distribuições transmutadas de rank cúbico. Usando a metodologia apresentada nesta primeira generalização, dois modelos foram considerados para compor as novas distribuições transmutadas cúbica: os modelos log-logístico e Weibull. Diante de problemas apresentados na classe transmutada de ordens quadrática e cúbica (tal como o espaço paramétrico restrito do parâmetro de transmutação λ), propomos neste trabalho, uma nova família de distribuição. Esta família, a qual chamamos e-transmutada ou e-extendida, é tão simples quanto o modelo transmutado, por incluir um único parâmetro ao modelo base, porém mais flexível do que a classe de modelos transmutados, sendo esta classe um caso particular da família proposta. Além disso, apresenta propriedades importantes, como ortogonalidade entre os parâmetros do modelo base e o parâmetro de e-transmutação, e espaço paramétrico não restrito para o parâmetro de etransmutação ω, que é definido em toda reta real. Estudos de simulação e aplicações a dados reais foram realizados para todos os modelos e generalizações propostas.

Neste trabalho propomos gráficos de controle tipo CUSUM para monitoramento de tempos de sobrevivência. Nossa proposta é desenvolver diferentes estatísticas para o escore do gráfico CUSUM de forma prospectiva. Inicialmente propomos um gráfico CUSUM não paramétrico para monitoramento de populações homogêneas que avalia a variação na estatística log-rank como forma de identificar se há uma mudança significativa no risco de falha ao longo do tempo. Algumas abordagens diferentes foram consideradas e em destaque colocamos o gráfico ZDiff CUSUM, que tem como escore o incremento na estatística Z do teste log-rank em relação à inspeção anterior. Foi constatado, via simulação, que este método é eficiente. Posteriormente investigamos abordagens que levam em conta heterogeneidade na população por meio do modelo de Cox, considerando medidas baseadas na razão de verossimilhanças e em resíduos martingal e deviance. Através de simulações, verificou-se que o método com base na razão de verossimilhanças se mostrou ágil para detectar alteração na taxa de falha, quando se conhece a intensidade da mudança e este valor é informado na construção do teste. Por outro lado, os gráficos CUSUM com base em resíduos são mais simples e se mostraram eficazes para identificar aumentos no padrão da sobrevivência. Estes três métodos e o ZDiff CUSUM foram aplicados a dados de um estudo conduzido no Instituto do Coração (InCor) envolvendo pacientes com insuficiência cardíaca. Foi detectado que ao longo do tempo estes pacientes apresentam sobrevida maior, o que pode estar ligado à melhoria no tratamento e procedimentos realizados no hospital. Como conclusão, sugerimos que os gráficos tipo CUSUM com resíduos do modelo de Cox e o método não paramétrico com teste log-rank podem ser alternativas para utilização na prática em monitoramento de dados de sobrevivência. / In this work we propose CUSUM control charts to monitor survival times. Our proposal is to develop different statistics for the CUSUM chart score in a prospective way, to take into account SA approaches. We initially consider a non-parametric approach to monitor homogeneous populations. This CUSUM evaluates the variation on the log-rank test statistics as a way to identify significant changes in the risk of failure. Some different expressions for this have been considered and, in particular, we propose a ZDiff CUSUM chart computed as the increment on the log-rank test statistics Z at each inspection point in relation to the previous one. Based on simulation studies it was found that this method is efficient. Subsequently we investigated approaches that take into account heterogeneity in the population through the Cox model, considering measures based on the likelihood ratio and on martingal and deviance residuals. Through simulations, it was verified that the method based on the likelihood ratio was agile to detect a change in the hazard rate, when the intensity of the change is known and this value is informed in the construction of the test. On the other hand, CUSUM methods based on residuals are simpler and have been shown to be effective in identifying increases in survival pattern. These three methods and the ZDiff CUSUM were applied to a dataset from a study conducted at the Heart Institute (InCor) on patients with heart failure. It has been found that, over time, these patients have greater survival, which may be linked to improved treatment and procedures performed at the hospital. As a conclusion, we suggest that the CUSUM methods based on Cox model residuals and the nonparametric method on the log-rank test may be alternatives for practice in monitoring survival data.

Η προσωποποίηση του ιστού είναι ένα πεδίο που έχει κερδίσει μεγάλη προσοχή όχι μόνο στην ερευνητική περιοχή, όπου πολλές ερευνητικές μονάδες έχουν ασχοληθεί με το πρόβλημα από διαφορετικές μεριές, αλλά και στην επιχειρησιακή περιοχή, όπου υπάρχει μία ποικιλία εργαλείων και εφαρμογών που διαθέτουν ένα ή περισσότερα modules στη διαδικασία της εξατομίκευσης. Ο στόχος όλων αυτών είναι, εξερευνώντας τις πληροφορίες που κρύβονται στα logs του εξυπηρετητή δικτύου να ανακαλύψουν τις αλληλεπιδράσεις μεταξύ των επισκεπτών των ιστότοπων και των ιστοσελίδων που περιέχονται σε αυτούς. Οι πληροφορίες αυτές μπορούν να αξιοποιηθούν για τη βελτιστοποίηση των δικτυακών τόπων, εξασφαλίζοντας έτσι αποτελεσματικότερη πλοήγηση για τον επισκέπτη και διατήρηση του πελάτη στην περίπτωση του επιχειρηματικού τομέα. Ένα βασικό βήμα πριν την εξατομίκευση αποτελεί η εξόρυξη χρησιμοποίησης από τον ιστό, ώστε να αποκαλυφθεί τη γνώση που κρύβεται στα log αρχεία ενός web εξυπηρετητή. Εφαρμόζοντας στατιστικές μεθόδους και μεθόδους εξόρυξης δεδομένων στα web log δεδομένα, μπορούν να προσδιοριστούν ενδιαφέροντα πρότυπα που αφορούν τη συμπεριφορά πλοήγησης των χρηστών, όπως συστάδες χρηστών και σελίδων και πιθανές συσχετίσεις μεταξύ web σελίδων και ομάδων χρηστών. Τα τελευταία χρόνια, γίνεται μια προσπάθεια συγχώνευσης του περιεχομένου του ιστού στη διαδικασία εξόρυξης χρησιμοποίησης, για να επαυξηθεί η αποτελεσματικότητα της εξατομίκευσης. Το ενδιαφέρον σε αυτή τη διπλωματική εργασία εστιάζεται στο πεδίο της εξόρυξης γνώσης για τη χρησιμοποίηση δικτυακών τόπων και πώς η διαδικασία αυτή μπορεί να επωφεληθεί από τα χαρακτηριστικά του σημασιολογικού ιστού. Αρχικά, παρουσιάζονται τεχνικές και αλγόριθμοι που έχουν προταθεί τα τελευταία χρόνια για εξόρυξη χρησιμοποίησης από τα log αρχεία των web εξυπηρετητών. Έπειτα εισάγεται και ο ρόλος του περιεχομένου στη διαδικασία αυτή και παρουσιάζονται δύο εργασίες που λαμβάνουν υπόψη και το περιεχόμενο των δικτυακών τόπων: μία τεχνική εξόρυξης χρησιμοποίησης με βάση το PLSA, η οποία δίνει στο τέλος και τη δυνατότητα ενοποίησης του περιεχομένου του ιστού και ένα σύστημα προσωποποίησης το οποίο χρησιμοποιεί το περιεχόμενο του ιστοτόπου για να βελτιώσει την αποτελεσματικότητα της μηχανής παραγωγής προτάσεων. Αφού αναλυθεί θεωρητικά το πεδίο εξόρυξης γνώσης από τα logs μέσα από την περιγραφή των σύγχρονων τεχνικών, προτείνεται το σύστημα ORGAN-Ontology-oRiented usaGe ANalysis- το οποίο αφορά στη φάση της ανάλυσης των log αρχείων και την εξόρυξη γνώσης για τη χρησιμοποίηση των δικτυακών τόπων με άξονα τη σημασιολογία του ιστοτόπου. Τα σημασιολογικά χαρακτηριστικά του δικτυακού τόπου έχουν προκύψει με τεχνικές εξόρυξης δεδομένων από το σύνολο των ιστοσελίδων και έχουν σχολιαστεί από μία OWL οντολογία. Το ORGAN παρέχει διεπαφή για την υποβολή ερωτήσεων σχετικών με την επισκεψιμότητα και τη σημασιολογία των σελίδων, αξιοποιώντας τη γνώση για το site, όπως αναπαρίσταται πάνω στην οντολογία. Περιγράφεται διεξοδικά ο σχεδιασμός, η ανάπτυξη και η πειραματική αξιολόγηση του συστήματος και σχολιάζονται τα αποτελέσματα του. / Web personalization is a domain which has gained great momentum not only in the research area, where many research units have addressed the problem form different perspectives, but also in the industrial area, where a variety of modules for the personalization process is available. The objective is, researching the information hidden in the web server log files to discover the interactions between web sites visitors and web sites pages. This information can be further exploited for web sites optimization, ensuring more effective navigation for the user and client retention in the industrial case. A primary step before the personalization is the web usage mining, where the knowledge hidden in the log files is revealed. Web usage mining is the procedure where the information stored in the Web server logs is processed by applying statistical and data mining techniques such as clustering, association rules discovery, classification, and sequential pattern discovery, in order to reveal useful patterns that can be further analyzed. Recently, there has been an effort to incorporate Web content in the web usage mining process, in order to enhance the effectiveness of personalization. The interest in this thesis is focused on the domain of the knowledge mining for usage of web sites and how this procedure can get the better of attributes of the semantic web. Initially, techniques and algorithms that have been proposed lately in the field of web usage mining are presented. After, the role of the context in the usage mining process is introduced and two relevant works are presented: a usage mining technique based on the PLSA model, which may integrate attributes of the site content, and a personalization system which uses the site content in order to enhance a recommendation engine. After analyzing theoretically the usage mining domain, a new system is proposed, the ORGAN, which is named after Ontology-oRiented usaGe ANalysis. ORGAN concerns the stage of log files analysis and the domain of knowledge mining for the web site usage based on the semantic attributes of the web site. The web site semantic attributes have resulted from the web site pages applying data mining techniques and have been annotated by an OWL ontology. ORGAN provides an interface for queries submission concerning the average level of visitation and the semantics of the web site pages, exploiting the knowledge for the site, as it is derived from the ontology. There is an extensive description of the design, the development and the experimental evaluation of the system.

This paper develops a new approach to the analysis of longitudinal paired comparison data, where comparisons of the same objects by the same judges are made on more than one occasion. As an alternative to other recent approaches to such data, which are based on Kalman filter- ing, our approach treats the problem as one of multivariate multinomial data, allowing dependence terms between comparisons over time to be incorporated. The resulting model can be fitted as a Poisson log-linear model and has parallels with the quadratic binary exponential distribution of Cox. An example from the British Household Panel Survey illustrates the approach. (author´s abstract) / Series: Research Report Series / Department of Statistics and Mathematics

There have been no studies analyzing the correlation between MAL Scales and sensorimotor impairment different levels in individuals post-stroke assessed by the Fugl-Meyer Scale. Objectives: To verify if there is a correlation between sensoriomotor impairment different levels of hemiparesis and the use of the paretic upper limb; to observe the differences between the MAL scales scores applied to individuals with varying degrees of impairment and to verify the dimensionality of the level of activity of scales MAL using Rasch analysis. Methods: Included 66 patients with chronic hemiparesis (n=49 - mild-moderate hemiparesis, n=17 - severe hemiparesis). All subjects were evaluated by Fugl-Meyer Scale, Mini Mental State Examination, and MAL (versions 30, 4/5 and MAL 50 – sum of the versions). The Pearson correlation test verified the correlation between the Fugl- Meyer for upper limb and the amount and quality of use scales of MAL. A one-way ANOVA for repeated measures with Bonferroni adjustment was used for each group to verify differences between MAL scales scores. In addition, the level of difficulty of the MAL activities was evaluated by the Rasch model. Results: There was high significant positive correlation between the scores of Fugl-Meyer scale and amount of use scale of MAL 30 (r = 0.76; p <0.001), MAL 4/5 (r = 0.78; p <0.001) and MAL 50 (r = 0.77; p <0.001). The amount of use and quality scale of the 3 results were different for mildmoderate hemiparesis (p <0.001). The MAL 4/5 showed the highest score compared to MAL 30 and MAL 50 in severe hemiparesis (p <0.001). The activities were ordered as the difficulty of execution, however, the MAL 4/5 activities were not the easiest. Conclusion: The higher the degree of motor impairment in hemiparesis, lower the use of the affected upper limb evaluated by MAL scale and the difficulty of the activities influences the amount of use and the quality of the affected upper limb in these individuals. The MAL 4/5, developed for individuals with severe motor impairment, does not present all the activities with less difficulty than the original scale. / A Motor Activity Log (MAL) avalia o uso espontâneo do membro superior afetado para realização das atividades diárias em ambientes reais em indivíduos hemiparéticos após Acidente Vascular Encefálico (AVE), refletindo a habilidade funcional desses indivíduos. Não foram encontrados estudos analisando a correlação entre as escalas MAL e os diferentes níveis de comprometimento sensoriomotor de pacientes pós-AVE avaliados na escala de Escala Fugl-Meyer. Objetivos: Verificar se há correlação dos diferentes níveis de comprometimento sensoriomotor da hemiparesia com o uso do membro superior parético; se há diferença entre as pontuações das escalas MAL aplicada a indivíduos com diferentes graus de comprometimento; e verificar a dimensionalidade dos níveis das atividades das escalas MAL usando a análise de Rasch. Métodos: Participaram 66 indivíduos com hemiparesia crônica (n=49-hemiparesia levemoderada, n=17-hemiparesia grave). Todos foram avaliados por meio da escala Fugl- Meyer, Mini Exame do Estado Mental, e MAL (versões 30, 4/5 e MAL 50-junção das versões). O teste de correlação de Pearson verificou a correlação entre a Fugl-Meyer para membro superior e as escalas de quantidade e qualidade da MAL. Uma ANOVA One-Way de medidas repetidas com ajuste de Bonferroni foi utilizada para cada grupo para verificar diferenças entre as pontuações nas escalas MAL. Além disso, o nível de dificuldade das atividades da MAL foi avaliado pelo modelo Rasch. Resultados: Houve alta correlação significativa e positiva entre as pontuações da escala Fugl-Meyer e da Escala de Quantidade de movimento da MAL 30 (r=0,76; p<0,001), MAL 4/5 (r=0,78; p<0,001) e MAL 50 (r=0,77; p<0,001). As pontuações das Escalas de Quantidade e Qualidade dos 3 resultados são diferentes entre si para o grupo hemiparesia levemoderada (p<0,001). A MAL 4/5 apresentou maior pontuação quando comparada com a MAL 30 e a MAL 50 no grupo hemiparesia grave (p<0,001). As atividades foram ordenadas conforme a dificuldade de execução, no entanto, as atividades da MAL 4/5 não são as mais fáceis. Conclusão: Quanto maior o grau de comprometimento sensoriomotor em hemiparéticos, menor o uso do membro superior afetado avaliado pela escala MAL, e dificuldade das atividades influencia na quantidade e qualidade do uso do membro superior afetado nesses indivíduos. A MAL 4/5, desenvolvida para indivíduos com grave comprometimento sensoriomotor, não apresenta todas as atividades com grau de dificuldade menor em relação à escala original.

The research problem was to see how productivity is affected by the adoption of environmental management practices by analyzing the interaction between the productivity factor and other environmental management factors. To do so, we estimated the linear type regression analysis, to obtain a mathematical equation which quantify the relationship between productivity and other variables. The survey was conducted in 60 shrimp farms located in CearÃ, on farms intended only for fattening phase. Were raised environmental management practices adopted by producers and created management indices,where these indices were aggregated into a single index that along with the variables that describe the productive characteristics and location of the farms originated econometric linlog semi-logarithmic models. Regression analysis showed that the yield is better explained by the storage density, intensive production system periodic servicing. Environmental management is not configured as a factor that influences productivity, justifying the low level of environmental management by shrimp farmers. / A carcinicultura vem se consolidando como uma das mais promissoras atividades econÃmicas da RegiÃo Nordeste, onde tambÃm tem sido apresentada como responsÃvel por elevados impactos negativos sobre o ambiente costeiro.
