The Roman Pantheon : scale-model collapse analyses
… analytical and experimental results on a 1:100 scale model of the variable thickness, hemispherical dome. The model is created using additive manufacturing for accuracy. This thesis, using a physical scale model, quantifies the safety of the Roman Pantheon against the two most probable causes of …

Testing of the suspended vehicle system scale model
A 1/24th scale model of the SVS (Suspended Vehicle System) guideway was constructed, instrumented, and tested. The model simulated five 250-ft-spans of the cable-stayed guideway for high-speed mass transportation type vehicles. Model vehicles consisting of single bogeys and single cars were …

Bivariate Log Location-Scale Model For Interval-Censored Data
… In this thesis, I consider a selected bivariate model concerning censored data. I rst review three basic univariate models, leading to corresponding bivariate models, in more complicated forms. Also I will discuss the properties of an actual, selected bi- variate model with interval-censored …

A scale model study of displacement ventilation with chilled ceilings
… increase the cooling capacity of the system. A scale model study was carried out to determine comfort levels at different conditions, to establish maximum cooling loads and to observe flow patterns in a typical office room with displacement ventilation and a chilled ceiling. Refrigerant R114 was …

A GIS-Based Landscape Scale Model for Native Bee Habitat
… in agriculture occur because of a lack of large scale analysis methods for native bees, regional species lists and management knowledge. This research explores the use of GIS in modeling native bee habitat to provide a landscape scale analysis method for native bees and develop a systematic …

Scale Model Shake Table Testing of Underground Structures in Soft Clay
… filling that empirical gap through the use of scale model shake table testing. Underground seismic soil-structure interaction (USSSI) effects were investigated for a stiff rectangular tunnel cross-section embedded within soft clay. San Francisco Young Bay Mud was used as a prototype soil for …

Scale-model investigation of brittle tunnel failure using a true-triaxial device
… focused on (1) developing an analog brittle rock model, (2) performing a series of tunnel model tests using a true-triaxial cell, a mock miniature tunnel boring machine (TBM), and acoustic emission (AE) monitoring, and (3) proposing more robust analytical methods and predictive models for brittle …

Scale Model Shake Table Testing of Seismic Earth Pressures in Soft Clay
<p>This research consists of scale model shake table tests to investigate the development of seismic earth pressures in soft clay. The soft clay was modeled after prototype San Francisco Bay Mud consisting of a mixture of kaolinite, bentonite, class C fly ash and water. A flexible walled testing …

Scale Model Shake Table Testing of Shallow Embedded Foundations in Soft Clay
… research involves shake table testing of 1g scale models that mimic the coupled seismic response of a structure on a shallow mat foundation and foundation soil (known as soil-foundation-structural-interaction or SFSI). In previous research, SFSI effects have been quantified through analytical …

How the Heart Grows: From Multi-scale Data to a Multi-scale Model
… of the entire looping process) using a multi-scale and multi-disciplinary approach. First, an experimental pipeline was developed to obtain data at different biological scales from cell to organism in a single embryo. Utilising the pipeline on embryos at different time-points resulted in a …

A cross-scale model for the evolution of influenza within a single season
In this thesis we develop a mathematical cross-scale model for the evolution of influenza within a single season. We model evolution as the emergence and spread of a mutant strain in a population that is already invaded by a parent resident strain. This allows us to investigate both the emergence …

A quantitative framework For large-scale model estimation and discrimination In systems biology
Using models to simulate and analyze biological networks requires principled approaches to parameter estimation and model discrimination. We use Bayesian and Monte Carlo methods to recover the full probability distributions of free parameters (initial protein concentrations and rate constants) for …

Testing the Assumption of Sample Invariance of Item Difficulty Parameters in the Rasch Rating Scale Model
<p>Rasch is a mathematical model that allows researchers to compare data that measure a unidimensional trait or ability (Bond & Fox, 2007). When data fit the Rasch model, it is mathematically proven that the item difficulty estimates are independent of the sample of respondents. The purpose of this …
