Mechanistic models of oceanic nitrogen fixation
… employ simple analytical theories and numerical models of ecosystems and biogeochemical cycles, and closely refer to direct observations of the phytoplanktonic community and geochemical tracers of the marine nitrogen cycle. Time-series observations of geochemical tracers and abundances of …

Mechanistic models of recruitment variability in fish populations.
… This thesis presents simple stochastic, mechanistic larval growth models, developed and utilised to investigate recruitment probabilities and variability. The models are mechanistic in that they are based on consideration of the key ecological processes at work, and not on statistical …

Physiologically-Based Kinetics and Mechanistic Models to Assess Exposure to Chemicals
… testing alternative methods such as in silico models are increasingly being used. Also, increasing emphasis is being placed on understanding mechanisms and pathways of toxicity as well as quantifying exposure which leads to an adverse effect in individuals. Physiologically-based kinetic and …

Physics-informed Deep Learning and Differentiable Mechanistic Models for Multicomponent Transport Phenomena
… differential equation (PDE)-based continuum models that introduce a multitude of physical assumptions to improve computational tractability. These assumptions typically oversimplify the governing dynamics posing significant challenges to model generalization at new operating conditions. …

Mechanistic modelling of single-floor office environments
… order to deploy systems effectively, propagation models that can reliably and yet efficiently characterise radio propagation behaviour are needed. This thesis describes the philosophy, the logical development, and the performance of a mechanistic modelling approach which is intended for use in …

Vulnerability assessment of extended end-plate connections under mainshock-aftershock sequences
… understand the behavior of the joints, and models were developed in order to simulate their complex behaviors. The models included numerical finite element models, mathematical models, and mechanistic models. While all models have their limitations, mechanistic models have been shown to …

ANALYSIS AND BEHAVIOR OF SEGMENTED ENERGY ABSORBING STEEL PLATE SHEAR WALLS (SEA-SPSWs)
… the plate segments are optimized using simple mechanistic models and henceforth, the mechanistic models are validated by finite element analysis. A comparative study is then carried out to demonstrate the effectiveness of the proposed SEA-SPSW system against a conventional steel plate shear …

Interference Modelling for Indoor Wireless Systems using the Finite-Difference Time-Domain Method
… in the presence of interference, reliable models to predict signal strengths (and other channel parameters) are required. Currently, empirical models based on experimental measurements are widely used. However, these models inherently lack an electromagnetic or physical basis and can vary …

Modelling, Simulation and Optimisation of Multistage Humidification and Dehumidification Desalination Plant Using Solar Energy. Performance Evaluation and Improvement of the Humidification-Dehumidification Desalination Process through Modelling, Simulation and Optimisation Techniques
… aim of this research was to build the detailed mechanistic models with the increased capability to predict more accurately as well as to simulate and optimise the Multistage Humidification-Dehumidification (MHDH) desalination plant which is powered by solar energy. The poor prediction accuracy …

Modes and mechanisms of hfq mediated stress regulation in bacteria
… promote integrated response to stress. Current mechanistic models that are present to describe Hfq functions cannot explain the complexity at which Hfq performs gene regulation. In this work we have used a variety of biophysical, biochemical and biological approaches to understand the nature of …

The foraging behaviour of granivorous birds: a mechanistic perspective.
… is often central to behavioural-based population models that predict the effect of environmental changes on populations based on the assumption that each individual tries to maximise its fitness at all times. 2. The functional response is a well studied phenomenon for some groups of foragers and …

A tool for automated inference in rule-based biological models
Rule-based biological models help researchers investigate systems such as cellular signalling pathways. Although these models are generally programmed by hand, some research efforts aim to program them automatically using biological facts extracted from papers via natural language processing. …

AN EXAMINATION OF BINDING DIFFERENCES AMONG MISMATCH REPAIR RECOGNITION PROTEINS WITH MISMATCH AND CISPLATIN DAMAGED DNA
… effects of cisplatin treatment. Proposed mechanistic models for mismatch repair involvement require recognition of the damage site. To examine these models, E. coli MutS, S. cerevisae MSH2-MSH6, and MSH2-MSH3 were expressed to perform fluorescence anisotropy binding experiments and to …

Microstructural Heterogeneity and the Mechanical Behavior of Nanocrystalline Metals
… the in situ experiments, we have proposed simple mechanistic models to interpret these phenomena. Finally, we have shown that in nanoscale metal films with a homogeneous microstructure Bauschinger effect is substantially reduced.

Keeping it cool: mammal responses to microclimatic variation in disturbed Indonesian lowland forest.
… thesis combines field data and observations with mechanistic models of microclimate and biophysical models of animal bioenergetics to determine the impacts of forest edges and microclimate variation on mammals at a site of disturbed forest in the Sikundur region of Sumatra, Indonesia. First, I …

Effects of swelling on brain tissue mechanical properties by indentation
Constructing more in-depth models of the brain’s behavior has gained significant attention in recent years, particularly for the goal of modeling brain injury and function. Mechanical studies have improved in effectiveness with the development of more standard testing protocols and the contribution …

Mechanistic modeling of bacterial nutrient uptake strategies
… bacteria into microscale robots. Here I use toy, mechanistic models of single-cell metabolism that allow me to quantify the costs and benefits of various nutrient uptake strategies. I find that: (i) a sensing-uptake trade-off governs E. coli's regulation of maltose uptake and chemotaxis to …
