▼ The driving risk of novice teenagers is the highest during the initial period after licensure but decreases rapidly. This dissertation develops recurrent-event change-point models to detect the time when driving risk decreases significantly for novice teenager drivers. The dissertation consists of three major parts: the first part applies recurrent-event change-point models with identical change-points for all subjects; the second part proposes models to allow change-points to vary among drivers by a hierarchical Bayesian finite mixture model; the third part develops a non-parametric Bayesian model with a Dirichlet process prior. In the first part, two recurrent-event change-point models to detect the time of change in driving risks are developed. The models are based on a non-homogeneous Poisson process with piecewise constant intensity functions. It is shown that the change-points only occur at the event times and the maximum likelihood estimators are consistent. The proposed models are applied to the Naturalistic Teenage Driving Study, which continuously recorded textit{in situ} driving behaviour of 42 novice teenage drivers for the first 18 months after licensure using sophisticated in-vehicle instrumentation. The results indicate that crash and near-crash rate decreases significantly after 73 hours of independent driving after licensure. The models in part one assume identical change-points for all drivers. However, several studies showed that different patterns of risk change over time might exist among the teenagers, which implies that the change-points might not be identical among drivers. In the second part, change-points are allowed to vary among drivers by a hierarchical Bayesian finite mixture model, considering that clusters exist among the teenagers. The prior for mixture proportions is a Dirichlet distribution and a Markov chain Monte Carlo algorithm is developed to sample from the posterior distributions. DIC is used to determine the best number of clusters. Based on the simulation study, the model gives fine results under different scenarios. For the Naturalist Teenage Driving Study data, three clusters exist among the teenagers: the change-points are 52.30, 108.99 and 150.20 hours of driving after first licensure correspondingly for the three clusters; the intensity rates increase for the first cluster while decrease for other two clusters; the change-point of the first cluster is the earliest and the average intensity rate is the highest. In the second part, model selection is conducted to determine the number of clusters. An alternative is the Bayesian non-parametric approach. In the third part, a Dirichlet process Mixture Model is proposed, where the change-points are assigned a Dirichlet process prior. A Markov chain Monte Carlo algorithm is developed to sample from the posterior distributions. Automatic clustering is expected based on change-points without specifying the number of latent clusters. Based on the Dirichlet process mixture model, three clusters exist among the teenage drivers for… Advisors/Committee Members: Guo, Feng (committeechair), Deng, Xinwei (committee member), Kim, Inyoung (committee member), Hong, Yili (committee member).

▼ L'incorporation d'échangeurs de chaleur dans des géostructures conventionnelles comme les pieux peut extraire la chaleur du sol à des fins de chauffage et l'injecter dans le sol à des fins de refroidissement. Ces dernières années, des recherches ont été menées à l'échelle réelle et en laboratoire pour étudier l'effet de la température sur le comportement géotechnique de ces géostructures énergétiques ainsi que sur le sol environnant. En effet, ces géostructures énergétiques peuvent être soumises à des charges mécaniques cycliques et a des variations thermiques tout au long de leur durée de vie. L'objectif de cette étude était d'approfondir la compréhension du comportement du contact sable/argile-structure sous des charges thermomécaniques complexes. Un dispositif de cisaillement direct à température contrôlée permettant d'effectuer des essais monotones et cycliques à charge normale constante ou à rigidité normale constante a été mis au point. La réponse de l'interface aux effets thermiques sur le comportement mécanique des sols et l'interface sol-structure a été étudiée. Le sable de Fontainebleau et l'argile kaolin ont été utilisés comme substituts pour les sols sableux et argileux. Les résultats ont montré que les variations thermiques appliquées ont un effet négligeable sur la résistance au cisaillement de l'interface entre le sable et la structure du sol. Dans les échantillons d'argile, l'augmentation de la température a augmenté la cohésion et par conséquent la résistance au cisaillement, en raison de la contraction thermique pendant le chauffage. L'adhérence de l'interface argile-structure était inférieure à la cohésion des échantillons d'argile. Pour étudier les effets de la charge mécanique cyclique sur l'interface argile-structure à différentes températures, des essais de cisaillement direct monotone et cyclique à volume équivalent non drainé ont été réalisés sur l'interface argile-argile et argile-structure à différentes températures. Les résultats ont montré que le nombre de cycles jusqu'à la rupture pour l'essai d'interface argile-structure était inférieur à celui du cas argile-argile dans la même gamme de rapports de contraintes de cisaillement cycliques et moyennes. L'augmentation de la température a réduit le taux d'accumulation des contraintes et le nombre de cycles jusqu'à la rupture a été multiplié par 2 ou 3. Le taux de dégradation (paramètre de dégradation, t) a diminué de 16% avec un chauffage de 22 à 60 °C pour les différents rapports de contrainte cyclique testés. Un modèle d'interface sol-structure non isotherme basé sur la théorie de l'état critique a ensuite été développé. Le modèle non isotherme prend en compte l'effet de la température sur le taux de vide de l'interface avant le cisaillement. Le modèle est capable de saisir l'effet de la température sur l'interface sol-structure dans des conditions de charge normale constante et de rigidité normale constante pour les interfaces sableuses et argileuses. Les paramètres supplémentaires ont des significations physiques et peuvent être… Advisors/Committee Members: Masrouri, Farimah (thesis director), Cuisinier, Olivier (thesis director).

▼ Latent factor models are useful for summarizing information among multiple outcomes. In this thesis I apply semiparametric methods based on P-splines to latent factor models in order to estimate and test non-constant factor loadings, as well as estimate and test the nonlinear relationship between an observed continuous predictor and multiple observed outcomes that measure a latent factor. In the first chapter, I develop a modeling strategy that estimates non-constant factor loadings as functions of multiple covariates. A highlight of my algorithm is the optimization of a type of generalized cross-validation criterion within each iteration of the EM algorithm for estimating the smoothing parameters of the splines. Through simulation studies I show the advantage of correctly estimating the non-constant factor loadings in reducing bias for the estimated factor score. I apply my model to studying the correlation among four highly correlated PM2.5 constituents. In the second chapter I examine the use of likelihood ratio test (LRT) in assessing whether a factor loading is constant. In order to take into account the estimation of smoothing parameters in my testing procedure, I use maximum likelihood approach to smooth the P-splines, which treats the spline coefficients as random and I test the variance of the spline coefficients. importance sampling to compute the likelihood. I use a data-driven chi-square mixture approximation as the null LRT distribution. The method is applied to estimating the underlying lead exposure represented by four types of lead measurements on mothers from the ELEMENT study. In the third chapter I use P-splines to estimate and test deviations of the latent factor mean from a linear trend. I also make the connection between my semiparametric latent factor model to a class of linear mixed models that estimate an overall exposure effect for multiple outcomes. My algorithm is based on standard linear mixed model and is implemented by adapting PROC MIXED from SAS into an iterative procedure. I apply my model to studying the lead exposure effect on children's behaviors as measured by the psychometric battery BASC-2.

▼ A three part investigation of the seismic source spectra of earthquakes and explosions is described. First, two of the most widely used simple P wave spectral models of earthquakes and two leading models of explosions are reviewed to assess their implications for high frequency (>lHz) seismic discrimination of underground nuclear explosions from earthquakes. The models are then compared with North American events and a limited data set of Soviet Central Asian events. The earthquakes are consistent with a constant stress drop model which decays as cb~2 at high frequencies. The deeper (>700 m) Nevada Test Site (NTS) explosions also show a of2 fall off between 10 and 30 Hz, in contrast with the shallower explosion which have a steeper decay. Near regional recordings of the September 14, 1988 Soviet JVE explosion show a higher comer frequency and lower 1 to 4 Hz P wave spectral ratios than predicted by either explosion model, and then predicted for similarly sized earthquakes. This high corner frequency may be influenced by source complications such as spall and tectonic release. The second part describes some simple forward modeling to quantify both the moment and the mechanism of the tectonic release of the Soviet JYE. Using 10-20 second Love and Rayleigh wave data we find the tectonic release moment to be from one fifth to one tenth of the explosion moment. To resolve the ambiguity in tectonic mechanism, synthetics were computed to compare the relative amplitudes of the SH and SV parts of the SmS phase. Although the character of the SmS phases are not completely matched, the strike slip model comes closer to matching the observed relative amplitudes than the reverse faulting mechanism. The final part describes a spectral model for the seismic radiation of a circular crack failing in tension. The model shows smaller S/P spectral ratios than are expected for pure shear crack sources. This model may be a useful first approximation for modeling seismic sources with some volumetric component, such as magma injection or slip on a non-planar fault.

▼ Today, the main research field for the automotive industry is to find solutions for active safety. In order to perceive the surrounding environment, tracking nearby traffic objects plays an important role. Validation of the tracking performance is often done in staged traffic scenarios, where additional sensors, mounted on the vehicles, are used to obtain their true positions and velocities. The difficulty of evaluating the tracking performance complicates its development. An alternative approach studied in this thesis, is to record sequences and use non-causal algorithms, such as smoothing, instead of filtering to estimate the true target states. With this method, validation data for online, causal, target tracking algorithms can be obtained for all traffic scenarios without the need of extra sensors. We investigate how non-causal algorithms affects the target tracking performance using multiple sensors and dynamic models of different complexity. This is done to evaluate real-time methods against estimates obtained from non-causal filtering. Two different measurement units, a monocular camera and a LIDAR sensor, and two dynamic models are evaluated and compared using both causal and non-causal methods. The system is tested in two single object scenarios where ground truth is available and in three multi object scenarios without ground truth. Results from the two single object scenarios shows that tracking using only a monocular camera performs poorly since it is unable to measure the distance to objects. Here, a complementary LIDAR sensor improves the tracking performance significantly. The dynamic models are shown to have a small impact on the tracking performance, while the non-causal application gives a distinct improvement when tracking objects at large distances. Since the sequence can be reversed, the non-causal estimates are propagated from more certain states when the target is closer to the ego vehicle. For multiple object tracking, we find that correct associations between measurements and tracks are crucial for improving the tracking performance with non-causal algorithms.
