Competition within random growth models
… with introducing competition into random models. It can be observed that there are two natural mechanisms for the evolution of a random model; either by growth or by self interactions. What we do is look at two types of models and introduce competition within them. The first model, the …

Bifurcation Analysis of Endogenous Growth Models
… the dynamics of the Uzawa-Lucas endogenous growth model. We examine the stability properties of both centralized and decentralized versions of the model and locate Hopf and transcritical bifurcation boundaries. In an extended analysis, we investigate the existence of Andronov-Hopf …

Analysis and numerical simulation of tumor growth models
… we focus on the numerical analysis of tumor growth models. Due to the difficulty of developing physically meaningful approximations of such models, we divide the main problem into more simple pieces of work that are addressed in the different chapters. First, in Chapter 2 we present a new …

A study on endogenous growth models and trade
In this study we look at the effects on economic growth of the continuous introduction of intermediate goods. Our theoretical framework enhances the endogenous growth theory, by allowing for participation in international trade. Furthermore, we test the behavior of the proposed theoretical model …

Nucleation and growth: models for faceted and layered materials
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-19 without embargo terms

Macroscopic order from reversible and stochastic lattice growth models
… is the use of physically motivated microscopic models of discrete systems which incorporate the constraints of locality, uniformity, and exact conservation laws. The features studied include: stochastic nonequilibrium fluctuations; use of pseudo-randomness in dynamical simulations; the …

Risk Sharing and Asset Returns in Stochastic Endogenous Growth Models
… cycle implications of a stochastic endogenous growth model with heterogeneous agents and incomplete markets are analyzed. The asset market structure of the economy is incomplete in the sense that households in the model economy can trade shares in a stock company and a risk free bond in …

The Effects of Fixed Factors of Production in Optimal Growth Models
… the effect of the fixed factor upon economic growth, I go on to further examine properties of the optimal growth path. Assuming a specific C.E.S. form for utility and fixing the amount of land available and an AK type production function (that is, for the model of chapter 2), we may calculate …

Sensitivity of two forest growth models to simulated pollution stress modifications
Two mathematical models (TASS and PT AEDA2) were applied to the study of long-term interactions of air pollution stress and forest growth and yield. TASS was previously developed to examine the dynamics and yield of Douglas-fIr, and PTAEDA2 was previously developed to examine individual tree growth …

Growth Models and Mortality Functions for Unthinned and Thinned Loblolly Pine Plantations
Effects of thinning, such as increased diameter growth and decreased mortality in the residual stand, have been recognized by foresters for many years. These effects are largely the result of increased tree vigor which is induced by a decreased level of competition. These relationships are …

Development of Urban Tree Growth Models Based on Site and Soil Characteristics
… trees from reaching their genetic potential for growth, longevity, and ecosystem function. To overcome these limitations, greater understanding of tree growth in the urban environment is needed. The goal of this research project was therefore to characterize a broad suite of soil characteristics …

The consequences of ignoring assessment date heterogeneity within waves for latent growth models
In traditional latent growth modeling, researchers assume that assessment dates within waves from longitudinal studies are homogeneous, although they are nearly always heterogeneous. In this study, we present a pedagogical illustration of assessing the consequences of ignoring time-point …

A NUMERICAL METHOD FOR ESTIMATING THE VARIANCE OF AGE AT MAXIMUM GROWTH RATE IN GROWTH MODELS
… outcome measure. The PHV is often derived from growth models such as the triple logistic model fitted to the stature (height) data. The age at PHV is sometimes ordinalized to designate an individual as an early, average or late maturer. In theory, age at PHV is the age at which the rate of …

Reducing Corn Yield Variability and Enhancing Yield Increases Through the Use of Corn-Specific Growth Models
Crop simulation models (CSMs) are used to evaluate management and environmental scenarios on crop growth and yields. Two corn (Zea Mays L.) crop growth simulation models, Hybrid-Maize, and CERES-Maize were calibrated and validated under Virginia conditions with the goal of better understanding corn …

Mirando Hacia el Futuro: Using Multilevel Growth Models to Examine the Achievement Gap Between White and Hispanic Students
… differences in math achievement. A multilevel growth curve model was used to examine the initial levels of, and changes in, achievement for White and Hispanic students within schools and how this varies across schools. In addition, a series of growth models examined trajectories of math …
