Exploratory Assessment Of Roadway Infrastructure Adaptation To The Impacts Of Sea-Level Rise, Mostafa Batouli
Exploratory Assessment Of Roadway Infrastructure Adaptation To The Impacts Of Sea-Level Rise, Mostafa Batouli
FIU Electronic Theses and Dissertations
Transportation agencies in coastal urban areas face a significant challenge to enhance the long-term resilience of their networks to flooding and storm surge events exacerbated by sea level rise. The problem of sea-level rise adaptation is characterized by deep uncertainty that makes it complex to assess the value of adaptation investments. To enable informed adaptation decisions, the present study created a dynamic stochastic modeling framework based on the theoretical underpinnings of complex adaptive systems that integrates: (i) stochastic simulation of sea-level rise stressors based on the data obtained from downscaled climate studies pertaining to future projections of sea-level and precipitation; …
On Some Test Statistics For Testing The Population Skewness And Kurtosis: An Empirical Study, Yawen Guo
On Some Test Statistics For Testing The Population Skewness And Kurtosis: An Empirical Study, Yawen Guo
FIU Electronic Theses and Dissertations
The purpose of this thesis is to propose some test statistics for testing the skewness and kurtosis parameters of a distribution, not limited to a normal distribution. Since a theoretical comparison is not possible, a simulation study has been conducted to compare the performance of the test statistics. We have compared both parametric methods (classical method with normality assumption) and non-parametric methods (bootstrap in Bias Corrected Standard Method, Efron’s Percentile Method, Hall’s Percentile Method and Bias Corrected Percentile Method). Our simulation results for testing the skewness parameter indicate that the power of the tests differs significantly across sample sizes, the …
A System-Of-Systems Framework For Assessment Of Resilience In Complex Construction Projects, Jin Zhu
A System-Of-Systems Framework For Assessment Of Resilience In Complex Construction Projects, Jin Zhu
FIU Electronic Theses and Dissertations
Uncertainty is a major reason of low efficiency in construction projects. Traditional approaches in dealing with uncertainty in projects focus on risk identification, mitigation, and transfer. These risk-based approaches may protect projects from identified risks. However, they cannot ensure the success of projects in environments with deep uncertainty. Hence, there is a need for a paradigm shift from risk-based to resilience-based approaches. A resilience-based approach focuses on enhancing project resilience as a capability to cope with known and unknown uncertainty. The objective of this research is to fill the knowledge gap and create the theory of resilience in the context …
Simulation And Application Of Binary Logic Regression Models, Jobany J. Heredia Rico
Simulation And Application Of Binary Logic Regression Models, Jobany J. Heredia Rico
FIU Electronic Theses and Dissertations
Logic regression (LR) is a methodology to identify logic combinations of binary predictors in the form of intersections (and), unions (or) and negations (not) that are linearly associated with an outcome variable. Logic regression uses the predictors as inputs and enables us to identify important logic combinations of independent variables using a computationally efficient tree-based stochastic search algorithm, unlike the classical regression models, which only consider pre-determined conventional interactions (the “and” rules). In the thesis, we focused on LR with a binary outcome in a logistic regression framework. Simulation studies were conducted to examine the performance of LR under the …
