Environmental Design Space model assessment
… thesis uses multiple metrics to assess an EDS model of a Boeing 777 aircraft. Starting from a detailed description of the EDS framework, a description of EDS model creation is outlined. The aircraft and engine model is assessed by a comparison to an industry-developed model and changes to the …

A Model Assessment Tool for Classroom Technology Infrastructure in Higher Education
… first purpose is to establish a practical ideal model to assess current classroom technology infrastructure in higher education. Second, is to assess current classroom technology infrastructure at Texas State University. The final purpose is to provide recommendations for improving classroom …

NARCCAP Model Assessment and Future Projections For the Southeast United States
<p>Global climate models (GCMs) provide most climate change projections, but their coarse resolution must be downscaled to more local scales in order to conduct meaningful climate impact assessments. This dissertation investigates dynamically downscaled regional climate model (RCM) output from the …

Uncertainty Analysis of Biological Nonlinear Models Based on Bayesian Estimation
… based on realistic distribution for nonlinear models, especially biological models. Parameter estimation, random number generation, and uncertainty analysis are closely related in Monte Carlo simulation based model assessment. All three aspects are discussed in this study. Because of the …

Temporal examination of DNA methylation profile reprogramming in the promoter region of PGC-1α during the progression of insulin resistance and type 2 diabetes mellitus in rodent models
… copy number) alterations in C57/BL6 rodent models. These changes preceded overt disease onset, as classified by clinically utilized indices, which included the homeostatic model assessment for insulin resistance (HOMA-IR), the homeostatic model assessment for β-cell dysfunction (HOMA- β), …

Quantifying Uncertainty in Model Evaluation
As Machine Learning models have quickly evolved in the past decade, ways of measuring their potential haven’t. This proposal will pose that simple point estimate performance indicators are ill suited to describe models that exhibit inherent variability. Addressing classifier performance variability …

Application Of The Empirical Likelihood Method In Proportional Hazards Model
In survival analysis, proportional hazards model is the most commonly used and the Cox model is the most popular. These models are developed to facilitate statistical analysis frequently encountered in medical research or reliability studies. In analyzing real data sets, checking the validity of …

Estimating Non-homogeneous Intensity Matrices in Continuous Time Multi-state Markov Models
Multi-State-Markov (MSM) models can be used to characterize the behaviour of categorical outcomes measured repeatedly over time. Kalbfleisch and Lawless (1985) and Gentleman et al. (1994) examine the MSM model under the assumption of time-homogeneous transition intensities. In the context of …

A discrete RET Model for Micro- and Millimetre Wave Propagation through Vegetation
… on the availability of radiowave propagation models. In the particular case of land mobile radio systems and wireless fixed access systems, obstacles in the form of vegetation volumes, e.g formations of trees, are likely to influence radio propagation, giving rise to absorption and scattering …

Bayesian Model Selection in terms of Kullback-Leibler discrepancy
… article we investigate and develop the practical model assessment and selection methods for Bayesian models, when we anticipate that a promising approach should be objective enough to accept, easy enough to understand, general enough to apply, simple enough to compute and coherent enough to …

A Model-Based Planning and Control Framework for Parkour-Style Legged Locomotion
… a fundamental challenge. This thesis presents a model-based framework for parkour-style locomotion, enabling robots to execute highly dynamic maneuvers such as jumps, rolls, and flips with precision and robustness. A key challenge in planning these motions is selecting an appropriate dynamic …

Exploration and assessment of the environmental design space for commercial aircraft and future technologies
… impacts of a future noise reduction technology. Assessment of the EDS framework was accomplished with a probabilistic model assessment methodology. The assessment involved the selection of stochastic inputs and generation of output distributions through Monte Carlo simulations. A sensitivity …

Evaluation of GLEAMS considering parameter uncertainty
… from the GLEAMS nonpoint source pollution model. Assessment of both the procedure and model was made by comparing absolute and relative predictions made with both probabilistic and deterministic procedures. Field data used came from a study of pesticide fate and transport in both no-till …

Is Increased Water Consumption Among Older Adults Associated with Improvements in Glycemia?
… and fasting glucose, insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) may provide further insight into the relationship between dehydration and diabetes risk. To our knowledge, few investigations have addressed this relationship between dehydration, impaired glycemia, …
