Streszczenie:
Profile monitoring is a relatively new approach in quality control best used where the process data follow a profile (or curve) at each time period. The essential idea for profile monitoring is to model the profile via some parametric, nonparametric, and semiparametric methods and then monitor the fitted profiles or the estimated random effects over time to determine if there have been changes in the profiles. The majority of previous studies in profile monitoring focused on the parametric modeling of either linear or nonlinear profiles, with both fixed and random effects, under the assumption

Streszczenie:
Linear mixed-effects (LME) models are frequently used for modeling longitudinal data. One complicating factor in the analysis of such data is that samples are sometimes obtained from a population with significant underlying heterogeneity, which would be hard to capture by a single LME model. Such problems may be addressed by a finite mixture of linear mixed-effects (FMLME) models, which segments the population into subpopulations and models each subpopulation by a distinct LME model. Often in the initial stage of a study, a large number of predictors are introduced. However, their associations

With the introduction of different forms of adaptive and actuated signal control, there is a need for effective evaluation tools that can capture the intricacies of real-life applications.

Alternatively, several microscopic simulation softwares are currently available for the evaluation of signalized intersections. The objective of this dissertation is fourfold.

Panel data analysis has become an important tool in applied econometrics and the respective statistical techniques are well described in several recent textbooks.

Of special importance is the choice between so-called fixed and random coefficient models. This choice can have a crucial effect on the interpretation of the analyzed phenomenon, which is demonstrated by an application on research and development spillover.

However, this survey was criticized and many different suggestions for improvement came from the scientific community. Some of them were selected and analysed and finally led to a new model.

The goal of this research is to expand the field of conformal predictions using Random Survival Forests. The standard Conformal Random Survival Forest can predict with a fixed certainty whether something will survive up until a certain time point. This research is the first to show that there is little practical use in the standard Conformal Random Survival Forest algorithm. It turns out that the confidence guarantees of the conformal prediction framework are violated if the Standard algorithm makes predictions for a user-controlled fixed time point.

Streszczenie:
In conventional tracking algorithms the targets are usually considered as point source objects. However, in realistic scenarios the point source assumption is often not suitable and estimating the states of an object extension characterized by a collectively moving ballistic object group (cluster) becomes a very critical and relevant problem which has applications in the defense area. Recently, a Bayesian approach to extended object tracking using random matrices has been proposed. Within this approach, ellipsoidal object extensions are modeled by random matrices and t

A especificação e metodologia adotadas no trabalho são as de Goldar e Aggawal (2004), que fazem uma análise de dados em painel para efeitos fixos e randômicos para as indústrias de transformação indianas como um todo e, posteriormente, aplicando os mesmos

Streszczenie:
In this thesis we study mean field interacting particle systems and their McKean-Vlasov limiting processes, in particular we focus on three different interaction mechanisms, mainly emerging from biological modelling. The first type of interaction is given by the so called simultaneous jumps. We consider a system of interacting jump-diffusion processes that interact by means of the discontinuous component: each particle performs a main jump and it simultaneously induces in all the other particles a simultaneous jump whose amplitude is rescaled with the size of the system. This peculiar interact

Streszczenie:
Elliptic curves were first proposed as a basis for public key cryptography in the mid 1980's. They provide public key cryptosystems based on the difficulty of the elliptic curve discrete logarithm problem (ECDLP) , which is so called because of its similarity to the discrete logarithm problem (DLP) over the integers modulo a large prime. One benefit of elliptic curve cryptosystems (ECCs) is that they can use a much shorter key length than other public key cryptosystems to provide an equivalent level of security. For example, 160 bit ECCs are believed to provide about the same level of security

Dans cette thèse, on construit un grand nombre de solutions globales pour de nombreuses équations de Schrödinger sur-critiques. Le principe consiste à rendre la donnée initiale aléatoire, selon les mêmes méthodes que Nicolas Burq, Nikolay Tzvetkov et Laurent Thomann afin de gagner de la dérivabilité.On considère d'abord l'équation de Schrödinger cubique en dimension 3. En partant de variables aléatoires gaussiennes et de la base de L^2(R^3) formée des fonctions d'Hermite tensorielles, on construit des ensembles de solutions globales pour des données initiales qui sont moralement dans L^2(R^3).

It also can offer the information for other tracking procedures such as data association and maneuvering adaptive procedure, etc. Two kinds of filters which are fixed parameters and random parameters, are analyzed in this thesis. Moreover, we also apply both filtering techniques to radar target tracking systems. According to the computer simulation results, the filter with random parameters has better performanc
