Seepage through longitudinal drainage trenches
… objective of this study was to determine how the longitudinal drain system works under laboratory conditions. In this study, a bench-scale model was constructed to assess the flow patterns caused by a trench drain in a slope. The experimental variables include the trench spacing (w), seepage depth …

Response Generation in Longitudinal Dialogues
Longitudinal Dialogues (LD) are the most challenging type of conversations for human-machine dialogue systems. LDs include the recollections of events, personal thoughts, and emotions specific to each individual in a sparse sequence of dialogue sessions. Dialogue systems designed for LDs should …

Heterogeneity modeling and longitudinal clustering
… in various personalization applications for longitudinal data. In the first application, we propose a personalized drug dosage recommendation scheme. Specifically, we model patients' heterogeneity using subject-specific random effects, and propose an adaptive procedure to estimate new …

Longitudinal dispersion in vegetated flow
… impacts. In this thesis, the focus is on longitudinal dispersion, which traditionally has been modeled by drawing analogy to rough boundary layers. This approach is inappropriate in many cases, as the vegetation provides a significant dead zone, which may trap scalars and augment …

Longitudinal misalignment based strain sensor
… measures strain by monitoring strain induced longitudinal misalignment in a novel fiber interconnection. This interconnection is created by aligning fibers within a segment of hollow core fiber. Related splice loss mechanisms are investigated for their effect on resolution. The effect of gauge …

Sorority Eating Patterns: A Longitudinal Investigation
… women and their eating patterns by conducting a longitudinal study, consisting of five assessments over the course of one academic year, to assess whether the sorority women who are engaging in maladaptive eating behaviors and thought processes had these problems before joining a sorority or …

Computational Support for Longitudinal Well-Being
… are still far from understanding our high-level, longitudinal behaviors, such as mental well-being. Early research about longitudinal behavior modeling and intervention is still facing a set of deployability challenges before being ready for real-world deployment. For behavior modeling, these …

Canonical Correlation Analysis for Longitudinal Data
… at multiple occasions or conditions leads to longitudinal multivariate data for a CCA. We address the problem of canonical correlation analysis on longitudinal data when the data have a Kronecker product covariance structure. Using structured correlation matrices we model the dependency of …

Semiparametric analysis of multivariate longitudinal data
… OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Longitudinal studies are conducted widely in fields such as agriculture and life sciences, business and industry, demography and other social sciences, medicine and public health. In longitudinal studies, individuals are measured repeatedly over …

Bayesian Analysis of Discrete Longitudinal Data
This thesis explores a Bayesian hierarchical model to compare treatment effectiveness for menopausal symptom relief. Specifically, this model recognizes the discrete nature of the data, as well as its time dependency. Bayesian analysis is used to make inference on each individual profile, as well …

Longitudinal analysis of platelet count data
… count dynamics and product failures. Using longitudinal data from the South African National Blood Service (SANBS), I employed linear mixed-effect models to analyse platelet count trajectories and latent class mixed models to uncover donor clusters with distinct patterns. The findings reveal …

Longitudinal air permeability of lodgepole pine
The longitudinal air permeabilities of the wood of 1116 specimens from 279 trees, two sapwood and two heartwood replicates, representing two varieties of lodgepole pine (Pinus contorta, vars. latifolia and murrayana) were measured with a steady state apparatus. It was found that the mean ratio of …

Longitudinal Slab Splitting in Composite Girders
Longitudinal slab splitting in composite hot rolled girders and joist girders was investigated. Two different type of framing configurations were studied with two tests conducted per configuration. The framing configurations were designated as either flush-framed or haunched, which describes the …

The analysis of longitudinal ordinal data
Longitudinal data, in which a series of observations is collected on a typically large number of experimental units is one of the most frequent and important sources of quantitative information in forestry. The dependencies among repeated observations for an experimental unit must be accounted for …

Sensitivity analysis of ship longitudinal strength
… (ULTSTR) for a sensitivity analysis of ship longitudinal strength, where this program was originally developed for calculating the collapse moment. Since the program is efficient it can be used to obtain ultimate strength variability for various values of parameters which affects the …

Longitudinal Trends in Early Childhood Napping Behaviours
This thesis explored longitudinal changes in nap behaviours among preschool-aged children, addressing inter- and intra-child variability. Using data from a large, nationally representative sample of Canadian children aged 1-6 years, Study One employed a generalized linear model to examine nap …
