Abstract (sommario):

In the present dissertation, we investigate two different nonparametric models; empirical Bayes model and functional deconvolution model. In the case of the nonparametric empirical Bayes estimation, we carried out a complete minimax study. In particular, we derive minimax lower bounds for the risk of the nonparametric empirical Bayes estimator for a general conditional distribution. This result has never been obtained previously. In order to attain optimal convergence rates, we use a wavelet series based empirical Bayes estimator constructed in Pensky and Alotaibi (2005). We prop

Abstract (sommario):

Nous étudions dans cette thèse l'influence de la grande dimension dans des problèmes de test et d'estimation. Notre analyse porte sur la dépendance en la dimension de la vitesse de séparation d'un test de proximité et du risque quadratique de l'estimation multiples de vecteurs. Nous complétons les résultats existants en étudiant ces dépendances dans le cas de distributions non isotropes. Pour de telles distributions, le rôle de la dimension est alors joué par des notions de dimension effective définies à partir de la covariance des distributions. Ce cadre permet d'englober des données de dimen

Abstract (sommario):

This thesis presents a timing error detector (TED) used in the symbol timing synchronization subsystem for digital communications. The new timing error detector is designed to minimize the probability of symbol decision error, and it is called minimum symbol error rate TED (MSERTED). The new TED resembles the TED derived using the maximum likelihood (ML) criterion but gives rise to faster convergence relative to MLTED. The new TED requires shorter training sequences for symbol timing recovery. The TED operates on the outputs of the matched filter and estimates the timing offset. The S-curve is

This work deals with the numerical-optimisation methods employed for assessing the minimum-lap-time of race vehicles.

Three vehicle models are proposed for the implementation in steady-state and dynamic simulations.

Abstract (sommario):

It is known that a matched filter is optimal for a signal corrupted by Gaussian noise. In a wireless environment, the received signal may be corrupted by Gaussian noise and a variety of other channel disturbances: cochannel interference, multiple access interference, large and small-scale fading, etc. Adaptive filtering is the usual approach to mitigating this channel distortion. Existing adaptive filtering techniques usually attempt to minimize the mean square error (MSE) of some aspect of the received signal, with respect to the desired aspect of that signal. Adaptive minimization of MSE

This is well above pre-crisis rates, 11.8% in 2007. According to the OECD, the modest increase in GDP forecasted for 2013 (1.2%) and the subsequent slow recovery in 2014 (2.3%) will be insufficient to create employment and reduce unemployment in a substantial way.It is particularly alarming that one every 11 young people are now unemp

The mean bait station visitation rate during 1999 - 2002 was 15.3% (SE = 2.89, n = 4).

This thesis examines the organizing strategies and successes of Afro-Argentine civil society organizations (CSO) in Buenos Aires.

Afro-Argentines are a highly understudied population due to the common belief that they do not exist in Argentina as a group. This thesis not only dispels that myth with a histo

An extended family of AlNiCo alloys was studied in this dissertation that consists of eight elements, and hence it is important to determine composition-property relationship between each of the alloying

The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. This has been contradicted by recent analyses estimating that the tick-borne flaviviruses emerged at least before 16,000 years ago. It has also been argued that the Powassan virus was introduced into North America at the time between the opening and splitting of the Beringian land bridge. Su

Abstract (sommario):

This thesis examined the ability to predict the emergence of bacteria resistant to antibiotics using genetic markers in the bacteria. Bacteria containing the genetic markers were able to become resistant to antibiotics, whereas bacteria that did not have the genetic markers remained susceptible. Existing techniques can identify the presence of resistance by looking at the characteristics of the bacteria during growth. However, having the ability to predict antibiotic resistance before it emerges could improve the preservation of currently available antibiotics and minimise treatment failure.

Abstract (sommario):

The content of this dissertation is divided into two main topics: 1) nonlinear profile monitoring and 2) an improved approximate distribution for the T^2 statistic based on the successive differences covariance matrix estimator. (Part 1) In an increasing number of cases the quality of a product or process cannot adequately be represented by the distribution of a univariate quality variable or the multivariate distribution of a vector of quality variables. Rather, a series of measurements are taken across some continuum, such as time or space, to create a profile. The profile determines the p

Abstract (sommario):

Dans cette thèse, nous nous intéressons au problème d'estimation de densité dans le modèle de convolution. Ce cadre correspond aux modèles avec erreurs de mesures additives, c'est-à-dire que nous observons une version bruitée de la variable d'intérêt. Pour mener notre étude, nous adoptons le point de vue de l'estimation non-paramétrique adaptative qui repose sur des procédures de sélection de modèle développées par Birgé & Massart ou sur les méthodes de Lepski. Cette thèse se divise en deux parties. La première développe des méthodes spécifiques d'estimation adaptative quand les variables

Abstract (sommario):

Uvod: Primarna fokalna hiperhidroza (PFH) je poremećaj nepoznate etiologije koji se karakteri&scaron;e prekomernim znojenjem na predilekcionim mestima. Podjednako se javlja kod osoba mu&scaron;kog i ženskog pola tokom dvadesetih i početkom tridesetih godina života, pri čemu se smatra da je učestalos PFH oko 2,8% u ukupnoj populaciji. Nastaje kao posledica hiperaktivnosti simaptičkog nervnog sistema ka znojnim žlezdama. Karakteristično je za PFH da se ne javlja noću, &scaron;to sugeri&scaron;e da emocionalni stimulus igra bitnu ulogu u nastanku ovog poremećaja. Bilateralna torakoskopska simpate

Abstract (sommario):

The dissertation deals with the issue of poverty in the Czech Republic, especially with its economic, political and historical context of development, theory and practice of its measurement and possible international comparability, both in scale and in terms of the effectiveness of social transfers system. The effectiveness is understood as reducing the extent of poverty represented by the at-risk-of-poverty rate used e.g. in Europe 2020 Strategy. The aim of the dissertation is to analyze the problem of income poverty and its development in the Czech Republic with a special focus on the effect

Abstract (sommario):

In this paper, I analyze the effectiveness of state level Earned Income Tax Credit programs on improving of poverty levels. I conducted this analysis for the years 1991 through 2011 using a panel data model with fixed effects. The main independent variables of interest were the state and federal EITC rates, minimum wage, gross state product, population, and unemployment all by state. I determined increases to the state EITC rates provided only a slight decrease to both the overall white below-poverty population and the corresponding white childhood population under 18, while both the overall a

Orientador: Claudio Alexandre Gobatto<br>Banca: Eduardo Kokubun<br>Banca: Herbert Gustavo Simões<br>Resumo: O limiar anaeróbio (LAN) tem sido muito utilizado como preditor da capacidade aeróbia na avaliação e prescrição do treinamento. Dentre os protocolos de determinação do LAN, o método do lactato mínimo (LM) parece ser um dos mais precisos, determinando de certa forma, individualmente os valores do LAN. Um outro modelo utilizado na avaliação do parâmetro aeróbio é o método não invasivo de determinação de potência crítica (PC), sendo que esse modelo possibilita também a quantificação das res
